[dpdk-dev] [PATCH 0/9] prepare for rte_device / rte_driver

[dpdk-dev] [PATCH 0/9] prepare for rte_device / rte_driver

[David Marchand]

Following discussions with Jan [1] and some cleanup I started on pci code,
here is a patchset that reworks pdev drivers registration and hotplug api.

The structures changes mentioned in [1] are still to be done, but at least,
I think we are one step closer to it.

Before this patchset, rte_driver .init semantics differed whether it
concerned a pdev or a vdev driver:
- for vdev, it actually meant that a devargs is given to the driver so
  that it creates ethdev / crypto objects, so it was a probing action
- for pdev, it only registered the driver triggering no ethdev / crypto
  objects

Patches 1 to 3 convert all existing pdev drivers into pci drivers and move
their registration in constructors.

Patch 4 might be of interest to Chelsio guys, following a regression they
reported [2].

Patches 5 and 6 align pci drivers and vdev drivers init.

Patches 7 to 9 move hotplug where it belongs.
I did not test patch 8 on FreeBSD (did not even compile it, for now).

[dpdk-dev] [PATCH 1/9] pci: no need for dynamic tailq init

[David Marchand]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH 2/9] pci: register all pdev as pci drivers

[David Marchand]

pdev drivers are actually pci drivers.
Wrappers for ethdev and crypto pci drivers, that assume a 1 to 1
association between pci device and upper device, have been added so that
current drivers are not impacted.

Re: [dpdk-dev] [PATCH 2/9] pci: register all pdev as pci drivers

It took me a while to find out what's going on in this patch. I could
see several not-so-related changes down the e-mail. I'd suggest to split
it this way:

1) separate coding style fixes
2) rename init/uninit to probe/remove (preserve the 'static' there)
3) remove rte_eth_driver_register invocations
4) separate VDEV and PDEV for cryptodev
5) play with the NEXT_ABI (remove those 'static' keywords?)

A more detailed commit log would help too. But this would
be automatically solved by the separation, I think.

See comments below...

Regards
Jan

I believe that you are making the driver independent on the exact
location of the pci_drv member in the rte_cryptodev_drivers struct. Is
it true? Why is that important?

So, I finally discovered that this change somehow separates the PCI
(PDEV) and VDEV initialization. Is that correct?

Here, I think you are trying to remove calls to the
rte_eth_driver_register as it does not do anything important.

Similar below (snipped)...

Coding style fixes should be in a separate patch. More occurences below
(snipped).

As I've suggested at the beginning, what about "first just rename then
make it public (non-static)"? I don't see the connection between the
rename and the NEXT_ABI conditional.

Yes, I rushed for this patchset to still be in the proposal window ...
Sorry, I will split for next version.

Globally, all my answers are "Yes, will do and it will be easier with
smaller patches".
Just added some comments where appropriate.

Yes, plus all other drivers are doing this, there were little
exception to this convention, so I just aligned here.

Yes.
I will separate crypto updates from netdev updates since crypto
framework has a slight different way of initialising.

I don't think we need NEXT_ABI checks here.
I am not breaking anything here, just adding a new symbol.

I will introduce this new symbol, then convert all existing
pdev/eth_driver to pdev/pci_driver in a second patch.

[dpdk-dev] [PATCH 3/9] drivers: no more pdev drivers

[David Marchand]

Now that pdev drivers have been converted to pci drivers, there is nothing
left in their init functions that can't go in a constructor.
pdev / vdev drivers init order is changed by this commit, but I can't see
why we would need to preserve it.

The only problem here, is that rte_qad_pmd is a crypto structure (same
problem with ethdev), so I can't just pass it to eal.
I can't just pass the pci driver, for the cases where multiple drivers
are registered in a single file (look at ixgbe driver).

So, how about :

In rte_pci.h :

#define RTE_EAL_PCI_REGISTER(name, d)\
void pciinitfn_ ##name(void);\
void __attribute__((constructor, used)) pciinitfn_ ##name(void)\
{\
        rte_eal_pci_register(d);\
}

Then, in qat driver :
RTE_EAL_PCI_REGISTER(qat, &rte_qat_pmd.pci_drv);

I meant
	rte_eal_pci_register(&(d)->pci_drv);\

Perhaps, my assumption that a PCI driver is always referred as pci_drv is wrong...

However, I think that this is a detail. Passing rte_pci_driver is good.

Well, I suppose we will always have a pci driver embedded in some
other internal pmd structure.
So we can always expect it to be called pci_drv ...

Btw, for drivers like mlx or virtio that need to do some more stuff in
their constructor (the iopl stuff for virtio is the most interesting
case, since the pci register happens only if iopl succeeded), we might
need some RTE_MODULE_INIT for those.

But in such a case, I think having RTE_MODULE_INIT in all pmds would
make more sense, and RTE_EAL_PCI_REGISTER looks unneeded ?

The Linux Kernel solves this by allowing both ways. You can do it by
hand and for most cases you can use just a simple oneliner.

So, we can have the RTE_(EAL_)MODULE_INIT for the general case. And then
eg. RTE_EAL_PCI_MODULE_INIT that makes the most common glue code to
register a single driver and who finally calls the RTE_EAL_MODULE_INIT.

[dpdk-dev] [PATCH 4/9] eal/linux: move back interrupt thread init before setting affinity

[David Marchand]

Now that virtio pci driver is initialized in a constructor, we only need to
move the interrupt thread init after loading the plugins.
This way, chelsio driver should be happy again [1].

Thank you for this patch.  I've tested it and it does improve the perf.
back when there is a queue on master lcore in l3fwd app.

Did you test the whole series ? or just this specific patch ?

Anyway, great, but this is still too fragile.

As discussed in the same thread as the problem you reported, there is
some work over there to be done so that interrupts are "distributed"
in a more flexible way.
Did someone look at this ?
Plans to work on this ? (post 2.3, I suppose)

I've tested only this particular patch, not the whole series.

[dpdk-dev] [PATCH 5/9] eal: get rid of pmd type

[David Marchand]

Now that we only have vdev drivers, there is no need for a pmd type in
rte_driver.
rte_driver is now purely a vdev thing, and could be renamed later
(then .init would become .probe, .uninit would become .remove).

What about something like:

#define	RTE_PMD_SET_TYPE(t)
#else
#define	RTE_PMD_SET_TYPE(t) .type = PMD_##t
#endif

and then just:

	RTE_PMD_SET_TYPE(VDEV),

Move this to a separate commit? Is it just a forgotten doc comment?

I cannot see the point why it is enclosed in the RTE_NEXT_ABI. Is it
such a serious breakage?

[dpdk-dev] [PATCH 7/9] pci: add a helper for device name

[David Marchand]

eal is a better place than ethdev for naming resources.
Add a helper here, and make use of it in ethdev hotplug code.

"size_t size" (or unsigned int) seems to be better to me.

The return value is not checked (below). I think, such functions
are usually missing error checking as nobody expects them to fail.
Wouldn't it be better to panic here?

What about pci_reload_device or pci_reload_device_info? I don't mind
too much, only the word 'refresh' reminds me other associations.

Just courious who provides this special file... is a DPDK-specific

I don't know whether this is a convention in DPDK, anyway, I don't
like to restrict errors to just negatives. You cannot write

if ((err = pci_refresh_device(...)) /* < 0 */) {
	handle_error(err);
}

as the check for < 0 is required (easy to be avoided).

Or maybe pci_update_device ?
I added pci_add_device in my other pci patchset, so update sounds better to me.

I don't know, just took the bsd pci code and plugged myself in it.
So for me this is a special bsd device.

This is mainly copy/paste.
Look at rte_eal_pci_scan() from lib/librte_eal/bsdapp/eal/eal_pci.c.

Well, as said above, this is copy/paste code.
But, anyway, when I write functions with goto statements, I prefer
having a minimal number of return statements, matter of taste.
Another way is to add two label error_close: error: but this is a bit
overkill here.

It is a remnant of a lot of code in eal that tries to have 0 for
success, < 0 for errors, > 0 for special cases.

All of them are OK. As for me, I prefer to not hide simple returns.

[dpdk-dev] [PATCH 9/9] eal: relocate hotplug code from ethdev

[David Marchand]

hotplug which deals with resources should come from the layer that already
handles them, i.e. eal.

[dpdk-dev] [PATCH v2 00/17] prepare for rte_device / rte_driver

[David Marchand]

Following discussions with Jan [1] and some cleanup I started on pci code,
here is a patchset that reworks pdev drivers registration and hotplug api.

The structures changes mentioned in [1] are still to be done, but at least,
I think we are one step closer to it.

Before this patchset, rte_driver .init semantics differed whether it
concerned a pdev or a vdev driver:
- for vdev, it actually meant that a devargs is given to the driver so
  that it creates ethdev / crypto objects, so it was a probing action
- for pdev, it only registered the driver triggering no ethdev / crypto
  objects

>From my pov, eal hotplug api introduced in this patchset still needs more
work so that it does not need to know about devargs. So a new devargs api
is needed.

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[1] http://dpdk.org/ml/archives/dev/2016-January/031390.html

[dpdk-dev] [PATCH v2 01/17] pci: no need for dynamic tailq init

[David Marchand]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v2 04/17] eal: remove duplicate function declaration

[David Marchand]

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v2 05/17] eal: introduce init macros

[David Marchand]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
RTE_EAL_PCI_REGISTER is added as a helper for pci drivers.

What about a simple version with just a single argument?

#define RTE_EAL_PCI_REGISTER(name)
RTE_INIT(pciinitfn_ ##name); \
static void pciinitfn_ ##name(void) \
{ \
	rte_eal_pci_register(&(name).pci_drv); \
}

Then the name pci_drv would be mandatory... But anyway, the 'name' and 'd'
are usually duplicates.

Regards
Jan

[dpdk-dev] [PATCH v2 08/17] drivers: convert all pdev drivers as pci drivers

[David Marchand]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

virtio and mlx* drivers use the general purpose RTE_INIT macro, as they both
need some special stuff to be done before registering a pci driver.

[dpdk-dev] [PATCH v2 11/17] eal/linux: move back interrupt thread init before setting affinity

[David Marchand]

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

this patch as root cause seems to be rte_debug.h missing an include for

[dpdk-dev] [PATCH v2 13/17] pci: add a helper to update a device

[David Marchand]

This helper updates a pci device object with latest information it can
find.
It will be used mainly for hotplug code.

[dpdk-dev] [PATCH v2 15/17] eal: add hotplug operations for pci and vdev

[David Marchand]

hotplug which deals with resources should come from the layer that already
handles them, i.e. eal.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v2 16/17] ethdev: convert to eal hotplug

[David Marchand]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

Now that hotplug has been moved to eal, there is no reason to keep the device
type in this layer.

OK, it works, my fault.

What is the way of removing the pmd_type? Would you like to introduce something like
rte_virt_device/driver pair for this purpose? Or should they use the rte_device/rte_driver
directly?

Other points:

* The devinit/devuninit should be generalized and moved to rte_driver, right?
* Fields name, drv_flags should be moved to rte_driver.
* Fields devargs, intr_handle, numa_node should be moved to rte_device.
* Do we want getter/setters for those? Otherwise, it always looks like pci_dev->dev.numa_node.

* What about pci_driver_list and pci_device_list? Should we have separated lists for every
  kind of device + driver? or should there be a single list (and so we have to put some
  discriminator into the rte_device/driver)? This influences placing of the TAILQ_ENTRY(...) next.
* if we move the next into the rte_driver/device and a discriminator of their type there, all
  TAILQ_FOREACH loops will look ugly as we have to check the discriminator...

Jan

The changes look good to me, nice to remove some of the duplication 
ethdev/cryptodev.

Regarding enabling hot-plugging for crypto devices it looks like it 
should be possible now to implement a mostly generic device 
attach/detach functions, just with a simple wrapper to identify a 
specific crypto or ethdev device structure. Do you have plans to do 
this? If not, I can have a look as I would like to enable hot-plugging 
for crypto devices, without duplicating things that still reside in the 
ethdev library at the moment.

Yes, I like them too.

Yes. But, first I focused on the new SoC infra to find out what can be
shared by the generic layer. I've got almost ready patch series, I will
post it soon to the mailing list. It does not introduce the generic
rte_driver/device yet, however, it shows that with

 [PATCH v2 00/17] prepare for rte_device / rte_driver

it is now possible to do it quite easily.

However, what I am not very sure about is whether we separate
management of the PCI devices and SoC devices and any other such
devices. Or whether we should have a single list for all.

Second, the rte_driver must be removed from DPDK as it conflicts
with the new rte_driver structure to be introduced. This should include
removing of pmd_type, I think. I've expected that David M. will continue
with v3 to move on (otherwise we'll get some merge conflicts I'd like to
avoid).

Another thing, there are structs like rte_pci_addr (etc.) which must
(but I am not so sure) be probably generalized as well.

And, devargs...

Jan

Patches 3,8,16 and 17 no longer apply to the latest master branch.
A rebase is needed.

With the recent most head (04920e6): 01, 03, 08, 15, 16 and 17 are failing.

Just wanted to check if there is a rebase of this series anytime soon?
I was looking at Jan's non-PCI patchset [1] and they are based on this series.

I will take care of this series if time permit.
It would help to have more reviews on other series touching EAL, like pmdinfo.

Re: [dpdk-dev] [PATCH v2 00/17] prepare for rte_device / rte_driver

[Jan Viktorin]

I think, we should consider to move it to somebody else. I would work on it, however, I don't see all the tasks that are to be done. That's why I was waiting to finalize those patchs by David or Thomas. For me, the important things were to generalize certain things to remove dependency on PCI. This is mostly done (otherwise the SoC patchset couldn't be done in the way I've posted it).

Now, there is some pending work to remove pmd_type. Next, to find out some generalization of rte_pci_device/driver to create rte_device/driver (I've posted several suggestions in the 0000 of SoC patchset).

What more?

We need a clean devargs API in EAL, not directly related to hotplug.
Then the hotplug can benefit of the devargs API as any other device config.

The EAL resources (also called devices) need an unique naming convention.

For the pmd_type removal, I am not very sure about the original David's intentions. What should be the result?

Should there be a special struct rte_virt_device or something like that?

Do we have some requirements for this? Would it be a complete redefinition
of the API? I don't see the relations to hotplug.

No idea about this. What do you mean by the unique naming convention?

Ok.
By the way, I have already rebased it on master. I can post the patches here if you want.
(only trivial conflicts were there)

Ok. I can try and review this, non-PCI/SoC and similar patchset in next few days.

Sounds good. +1

I'd rebase my patchset on top of it and repost.

The original David's patchset was quite OK. I didn't have any comments. The thing
is (from my POV) that it was incomplete.

[dpdk-dev] [PATCH v3 00/17] prepare for rte_device / rte_driver

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

* Original patch series is from David Marchand. This is just a rebase over
master (d76c19309) *

Following discussions with Jan [1] and some cleanup I started on pci code,
here is a patchset that reworks pdev drivers registration and hotplug api.

The structures changes mentioned in [1] are still to be done, but at least,
I think we are one step closer to it.

Before this patchset, rte_driver .init semantics differed whether it
concerned a pdev or a vdev driver:
- for vdev, it actually meant that a devargs is given to the driver so
  that it creates ethdev / crypto objects, so it was a probing action
- for pdev, it only registered the driver triggering no ethdev / crypto
  objects

>From my pov, eal hotplug api introduced in this patchset still needs more
work so that it does not need to know about devargs. So a new devargs api
is needed.

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[1] http://dpdk.org/ml/archives/dev/2016-January/031390.html

David Marchand (17):
  pci: no need for dynamic tailq init
  crypto: no need for a crypto pmd type
  drivers: align pci driver definitions
  eal: remove duplicate function declaration
  eal: introduce init macros
  crypto: export init/uninit common wrappers for pci drivers
  ethdev: export init/uninit common wrappers for pci drivers
  drivers: convert all pdev drivers as pci drivers
  crypto: get rid of crypto driver register callback
  ethdev: get rid of eth driver register callback
  eal/linux: move back interrupt thread init before setting affinity
  pci: add a helper for device name
  pci: add a helper to update a device
  ethdev: do not scan all pci devices on attach
  eal: add hotplug operations for pci and vdev
  ethdev: convert to eal hotplug
  ethdev: get rid of device type

[dpdk-dev] [PATCH v3 01/17] pci: no need for dynamic tailq init

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v3 04/17] eal: remove duplicate function declaration

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v3 05/17] eal: introduce init macros

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
RTE_EAL_PCI_REGISTER is added as a helper for pci drivers.

[dpdk-dev] [PATCH v3 08/17] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

virtio and mlx* drivers use the general purpose RTE_INIT macro, as they both
need some special stuff to be done before registering a pci driver.

Self review (as I rebased this series):

With this applied on master (3901ed99), it would cause issues with qede driver. qede driver uses the rte_eth_driver_register() function.
I will update it (qede driver) and post another version.

[dpdk-dev] [PATCH v3 11/17] eal/linux: move back interrupt thread init before setting affinity

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

[dpdk-dev] [PATCH v3 12/17] pci: add a helper for device name

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

eal is a better place than crypto / ethdev for naming resources.
Add a helper in eal and make use of it in crypto / ethdev.

[dpdk-dev] [PATCH v3 16/17] ethdev: convert to eal hotplug

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v3 17/17] ethdev: get rid of device type

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Now that hotplug has been moved to eal, there is no reason to keep the device
type in this layer.

[dpdk-dev] [PATCH v4 00/17] prepare for rte_device / rte_driver

[Shreyansh Jain]

* Original patch series is from David Marchand [1], [2].
* Cover letter text has been modified to make it author agnostic

David created the original patchset based on the discussions on list [3].
Being a large piece of work, this patchset introduces first level of changes
for generalizing the driver-device relationship for supporting hotplug.

Pending work, as per discussions in thread [3]:
- Heirarchical relationship between rte_driver/device, pci_*, crypto_*
- Cleaner device init/deinit methods (probably from rte_driver onwards)
- Moving generic flags/fields from pci_* structure to rte_* structure
- Removing dependency on devargs for pdev/vdev distinction
- Device/Driver lists: discussion and decision on separate or unified lists

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[dpdk-dev] [PATCH v4 01/17] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v4 05/17] eal: introduce init macros

[Shreyansh Jain]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
RTE_EAL_PCI_REGISTER is added as a helper for pci drivers.

RTE_EAL_PCI_REGISTER assumes that object expanded contains a pci_drv member.

[dpdk-dev] [PATCH v4 06/17] crypto: export init/uninit common wrappers for pci drivers

[Shreyansh Jain]

Preparing for getting rid of rte_cryptodev_driver, here are two wrappers
that can be used by pci drivers that assume a 1 to 1 association between
pci resource and upper interface.

[dpdk-dev] [PATCH v4 08/17] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

virtio and mlx* drivers use the general purpose RTE_INIT macro, as they both
need some special stuff to be done before registering a pci driver.

[dpdk-dev] [PATCH v4 11/17] eal/linux: move back interrupt thread init before setting affinity

[Shreyansh Jain]

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

hotplug which deals with resources should come from the layer that already
handles them, i.e. eal.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v4 16/17] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v5 00/17] Prepare for rte_device / rte_driver

[Shreyansh Jain]

* Original patch series is from David Marchand [1], [2].
* Cover letter text has been modified to make it author agnostic

David created the original patchset based on the discussions on list [3].
Being a large piece of work, this patchset introduces first level of changes
for generalizing the driver-device relationship for supporting hotplug.

Pending work, as per discussions in thread [3]:
- Heirarchical relationship between rte_driver/device, pci_*, crypto_*
- Cleaner device init/deinit methods (probably from rte_driver onwards)
- Moving generic flags/fields from pci_* structure to rte_* structure
- Removing dependency on devargs for pdev/vdev distinction
- Device/Driver lists: discussion and decision on separate or unified lists

This patchset is based on master (34d279)

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port which
  were removed by previous patchset. These are being used by pdump library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[dpdk-dev] [PATCH v5 01/17] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v5 03/17] drivers: align pci driver definitions

[Shreyansh Jain]

Pure coding style, but it might make it easier later if we want to move
fields in rte_cryptodev_driver and eth_driver structures.

[dpdk-dev] [PATCH v5 04/17] eal: remove duplicate function declaration

[Shreyansh Jain]

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

Fixes: e57f20e05177 ("eal: make vdev init path generic for both virtual and pci devices")

[dpdk-dev] [PATCH v5 05/17] eal: introduce init macros

[Shreyansh Jain]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
RTE_EAL_PCI_REGISTER is added as a helper for pci drivers.

[dpdk-dev] [PATCH v5 08/17] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

virtio and mlx* drivers use the general purpose RTE_INIT macro, as they both
need some special stuff to be done before registering a pci driver.

through a dedicated channel.

[dpdk-dev] [PATCH v5 11/17] eal/linux: move back interrupt thread init before setting affinity

[Shreyansh Jain]

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

[dpdk-dev] [PATCH v5 15/17] eal: add hotplug operations for pci and vdev

[Shreyansh Jain]

hotplug which deals with resources should come from the layer that already
handles them, i.e. eal.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v5 16/17] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v6 00/17] Prepare for rte_device / rte_driver

[Shreyansh Jain]

* Original patch series is from David Marchand [1], [2].
* Link with patch series [4] from Jan Viktorin for a more complete picture
  of proposed EAL device heirarchy changes.
* This might not be in-sync with pmdinfogen as PMD_REGISTER_DRIVER is
  removed [7].

David created the original patchset based on the discussions on list [3].
Being a large piece of work, this patchset introduces first level of changes
for generalizing the driver-device relationship for supporting hotplug.

This patchset is based on master (11c5e45d8)

Overview of this work as per David [3], as well as notes from Thomas, Jan:
- pdev -> PCI registeration using helpers (introduced in this series)
- removal of eth/crypto driver registeration callbacks. These are now handled
  by PCI registeration helpers (this patch)
- rte_device=>pci/vdev device heirarchy (by this [4] series)
- removal of PMD_PDEV type (this patch) and PMD_VDEV (by this [4] series)
- Support for hotplugging

In [5], Neil had NACK'd previous series due to removal of symbol from map file
without proper process. I continue with the same patch in this series as I
was not clear after Thomas's reponse [6] whether it is OK to remove these
(rte_cryptodev_pmd_driver_register, rte_eth_driver_register) or not - probably
some procedure of deprecation that I am skipping.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be in sync
  with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can be merged]
- Modifications to bnxt and thunderx driver PMD registeration files for
  using the simplified PCI device registeration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port which
  were removed by previous patchset. These are being used by pdump library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[dpdk-dev] [PATCH v6 01/17] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[Shreyansh Jain]

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v6 05/17] eal: introduce init macros

[Shreyansh Jain]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
DRIVER_REGISTER_PCI is added as a helper for pci drivers.

You are missing setting the name here like PMD_REGISTER_DRIVER does
now. Or should I include it in my patch set?

Moreover, it should accept the rte_pci_driver *, shouldn't it? Here, it
expects a wrapper around it (eth_driver)... I now, my SoC patches were
supposing the some... but I think it is wrong.

The original David's patch set contains calls like this:

  RTE_EAL_PCI_REGISTER(bnx2xvf, rte_bnx2xvf_pmd.pci_drv);

So, I think, we should go the original way.

That is a miss from my side.
I will publish v7 with this. You want this right away or should I wait a little while (more reviews, or any pending additions as per Thomas's notes) before publishing?

I have a slightly different opinion of the above.
IMO, aim of the helpers is to hide the PCI details and continue to make driver consider itself as a generic ETH driver. In that case, dereferencing pci_drv would be done by macro.

Also, considering that in future pci_drv would also have soc_drv, the helpers can effectively hide the intra-structure naming of these. It would help when more such device types (would there be?) are introduced - in which case, driver framework has a consistent coding convention.

But, I am ok switching back to David's way as well - I don't have any strong argument against that.

Please. The time is almost gone. 18/7/2016 is the release (according
to the roadmap)... I have to fix it in my patchset, otherwise it
does not build (after moving the .name from rte_pci_driver to
rte_driver).

In this case, I'd prefer to see DRIVER_REGISTER_PCI_ETH.

At first, this was also my way of thinking. But I've changed my mind. I
find it to be a bit overdesigned.

Hide? I am afraid, I don't understand clearly what you mean.

I'd like to preserve the clear semantics. That is DRIVER_REGISTER_PCI
-> give a pci device.

Has anybody a different opinion? David? Thomas?

I didn't consider 18/Jul.
Please go ahead. I will continue to send v7 _without_ the above change so that your patchset doesn't break. This way you will not get blocked because of me.

There is:

DRIVER_REGISTER_PCI(...)
DRIVER_REGISTER_PCI_TABLE(...)

Wouldn't DRIVER_REGISTER_PCI_ETH look out-of-place?

DRIVER_REGISTER_PCI(eth_driver)
DRIVER_REGISTER_SOC(eth_driver)
DRIVER_REGISTER_XXX(eth_driver)
...

In either case, the caller always creates the eth_driver and populates internal specific driver structure (pci_drv) as a sub-part of eth_driver specification. Macro 'hides' the internal structure name (pci_drv, soc_drv...).
But again, nothing critical. Just a way of usage. We might not even have a 'XXX' in near future.

Yes please.
Or else, if nothing comes up soon, I will simply go ahead and change to DRIVER_REGISTER_PCI(eth_driver.pci_drv) as this trivial issue shouldn't hold back this series.

I'm sorry I have no time to review these series shortly.

I think it is too late to consider an integration in 16.07 unfortunately.
I feel you are doing a great job and we can target to have these changes
in the early days of 16.11 (in August).
As this is a big refactoring, it is probably a good idea to integrate it
in the beginning of the next release integration cycle.

Now that we have already skipped the 16.07, I will fix this in my code and release an updated version as soon as 16.07 is officially available. Is that OK?

Also, I have fixed most review comments except [1]. I am still not sure of the impact of this change. So, I will publish the v7 without this and then probably a v8 in case this change has any impact. That way we can have your patchset not blocked because of this series.

Sure :). The thing is that during August-September, I've got significantly
less time for this then in June-July :/. That's why I was trying to fit in
the 16.07.

I have no idea about this. Hopefully, it's not a very serious thing.

Well, then lets try and get things out for review as soon as we can.
I have sent across v7 of rte_driver set.
Unfortunately, I forgot to add your sign-off. If the set works for you, can you bulk ack?

[dpdk-dev] [PATCH v6 06/17] crypto: export init/uninit common wrappers for pci drivers

[Shreyansh Jain]

Preparing for getting rid of rte_cryptodev_driver, here are two wrappers
that can be used by pci drivers that assume a 1 to 1 association between
pci resource and upper interface.

[dpdk-dev] [PATCH v6 07/17] ethdev: export init/uninit common wrappers for pci drivers

[Shreyansh Jain]

Preparing for getting rid of eth_drv, here are two wrappers that can be
used by pci drivers that assume a 1 to 1 association between pci resource and
upper interface.

[dpdk-dev] [PATCH v6 08/17] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

[dpdk-dev] [PATCH v6 11/17] eal/linux: move back interrupt thread init before setting affinity

[Shreyansh Jain]

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

OK.

This has historic context (from earlier version of this patch). 
But I could relate the word 'resources' to EAL representation of devices - whether PCI or Crypto.
Or, Resource == Device.

Agree that 'above' is positional word and should be avoided.
I will change that to "... using eal_parse_pci_* BDF helpers". OK?

We need to define a precise wording, especially for the words
	- interface
	- resource
	- device
	- driver
	- module
Following are my thoughts:

An interface is a view of a resource through an API (e.g. an ethdev port).
A resource is a well identified hardware (e.g. a PCI device id).
A device is a hardware function (e.g. a networking port).
Note that some PCI NICs have only one PCI device id for several ports
(Chelsio and Mellanox cases). That's why we need to distinguish device
and resource.

A driver is the code handling a device.
I have read the word module in some patch proposals but I don't really know
what it refers to. Is it a group of drivers in the same file/directory?

Well, yes, initially there was proposed a kind of module. However, after David
as sent the patchset prepare for rte_device/driver, you can see that there
is no need for such object (probably). A module might be helpful when thinking
about the metadata (as done by Neil Horman). But as far as I know there was no
need for this... So a module has no data abstraction now and I am not going to
make any.

If it is possible I'd like more "device". But I think it's not that critical thing...

If I go by what Thomas is proposing for meaning of 'resource' [1], and the fact that all methods in this patchset refer to 'devices', I will change the patch context to 'EAL is a better place than crypto / ethdev to name devices'.

[dpdk-dev] [PATCH v6 13/17] pci: add a helper to update a device

[Shreyansh Jain]

This helper updates a pci device object with latest information it can
find.
It will be used mainly for hotplug code.

Is this delete correct? The SYSFS_PCI_DEVICES was moved here from
rte_pci.h. A relict of some rebase?

Why adding SYSFS_PCI_DEVICES here? The pci_get_sysfs_path is used for
this purpose. Again, a rebase issue?

My miss - I had though of using pci_get_sysfs_path post v5, (as you have mentioned below) but while re-creating the patches I missed out.

Once pci_get_sysfs_path is used, this change would be redundant.

[dpdk-dev] [PATCH v6 15/17] eal: add hotplug operations for pci and vdev

[Shreyansh Jain]

Hotplug which deals with resources should come from the layer that already
handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

I think this log can be more specific. We have the name of the device.
It might be confusing to the user when the attach fails and there is
no simple way how to determine which one.

From my POV, the term "resource" is not good here. We have
rte_pci_resource but we refer to a device here. The function is called
rte_eal_DEV_attach. No idea why to call it a resource.

Agree. I will update with 'name'.

Your point of 'resource' for 'rte_eal_*dev*_attach' makes sense.
Ideally I wouldn't have given much heed to this - for me 'resource' is just a device representation within EAL.
But, now that you have highlighted, name<=>comment is certainly mismatch.

I will change.

[dpdk-dev] [PATCH v6 16/17] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

I am not sure about this comment. What is "no point"?

Isn't this also a potential bug? (Like the one below.) How could it
happen there is no port after a successful attach?

Should we log this? Or call some kind panic?

I'd be more specific about the failing device, we have its name.

Yes, even searching through code path I couldn't find a positive case where control would reach here without nb_ports>0.
Though, i am not sure if some rough application attempts to mix-up calls - and that, in my opinion, is not worth checking.
Should I remove it?

I will place a log because applications should have a chance to ignore a device which cannot be attached for whatever reason.

Agree. I will add 'name' to this.

At least a loud log might be helpful. If there is really no path to reach this point, I'd put RTE_VERIFY here.

OK, we just should shout loudly if it means a bug...

[dpdk-dev] [PATCH v6 17/17] ethdev: get rid of device type

[Shreyansh Jain]

Now that hotplug has been moved to eal, there is no reason to keep the device
type in this layer.

I understand that app_link_is_virtual is useless. However, it changes
semantics. What is the behaviour of the app_link_up_internal after this
change?

[dpdk-dev] [PATCH v7 00/17] Prepare for rte_device / rte_driver

[Shreyansh Jain]

* Original patch series is from David Marchand [1], [2].
* Link with patch series [4] from Jan Viktorin for a more complete picture
  of proposed EAL device heirarchy changes.
* This might not be in-sync with pmdinfogen as PMD_REGISTER_DRIVER is
  removed [7].

David created the original patchset based on the discussions on list [3].
Being a large piece of work, this patchset introduces first level of changes
for generalizing the driver-device relationship for supporting hotplug.

Overview of this work as per David [3], as well as notes from Thomas [9] &
Jan:
- pdev -> PCI registeration using helpers (introduced in this series)
- removal of eth/crypto driver registeration callbacks. These are now handled
  by PCI registeration helpers (this patch)
- rte_device=>pci/vdev device heirarchy (by this [4] series)
- removal of PMD_PDEV type (this patch) and PMD_VDEV (by this [4] series)
- Support for hotplugging

This patchset is based on master (b0a1419)

[9] http://dpdk.org/ml/archives/dev/2016-July/044086.html

Changes since v6:
- rebase over 16.07 (b0a1419)
- DRIVER_REGISTER_PCI macro is now passed pci_drv rather than drv
- review comments regarding missing information in log messages
- new API additions to 16.11 map objects
- review comment in [5] and [7] are not included in this series.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be in sync
  with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can be merged]
- Modifications to bnxt and thunderx driver PMD registeration files for
  using the simplified PCI device registeration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port which
  were removed by previous patchset. These are being used by pdump library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

David Marchand, Shreyansh Jain (17):
  pci: no need for dynamic tailq init
  crypto: no need for a crypto pmd type
  drivers: align pci driver definitions
  eal: remove duplicate function declaration
  eal: introduce init macros
  crypto: export init/uninit common wrappers for pci drivers
  ethdev: export init/uninit common wrappers for pci drivers
  drivers: convert all pdev drivers as pci drivers
  crypto: get rid of crypto driver register callback
  ethdev: get rid of eth driver register callback
  eal/linux: move back interrupt thread init before setting affinity
  pci: add a helper for device name
  pci: add a helper to update a device
  ethdev: do not scan all pci devices on attach
  eal: add hotplug operations for pci and vdev
  ethdev: convert to eal hotplug
  ethdev: get rid of device type

[dpdk-dev] [PATCH v7 01/17] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v7 05/17] eal: introduce init macros

[Shreyansh Jain]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
DRIVER_REGISTER_PCI is added as a helper for pci drivers.

[dpdk-dev] [PATCH v7 08/17] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

[dpdk-dev] [PATCH v7 11/17] eal/linux: move back interrupt thread init before setting affinity

[Shreyansh Jain]

Now that virtio pci driver is initialized in a constructor, iopl() stuff
happens early enough so that interrupt thread can be created right after
plugin loading.
This way, chelsio driver should be happy again [1].

[dpdk-dev] [PATCH v7 12/17] pci: add a helper for device name

[Shreyansh Jain]

Eal is a better place than crypto / ethdev to name devices.
Add a helper in eal and make use of it in crypto / ethdev.

[Shreyansh Jain]

Hotplug invocations, which deals with devices, should come from the layer that
already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v7 16/17] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v8 00/25] Introducing rte_driver/rte_device generalization

[Shreyansh Jain]

Based on master (e22856313fff2)

Background:
===========

It includes two different patch-sets floated on ML earlier:
 * Original patch series is from David Marchand [1], [2].
  `- This focused mainly on PCI (PDEV) part
  `- v7 of this was posted by me [8] in August/2016
 * Patch series [4] from Jan Viktorin
  `- This focused on VDEV and rte_device integration

Introduction:
=============

This patch series introduces a generic device model, moving away from PCI 
centric code layout. Key change is to introduce rte_driver/rte_device 
structures at the top level which are inherited by 
rte_XXX_driver/rte_XXX_device - where XXX belongs to {pci, vdev, soc (in 
future),...}.

Key motivation for this series is to move away from PCI centric design of 
EAL to a more hierarchical device model - pivoted around a generic driver 
and device. Each specific driver and device can inherit the common 
properties of the generic set and build upon it through driver/device 
specific functions.

Earlier, the EAL device initialization model was:
(Refer: [3])

--
 Constructor:
  |- PMD_DRIVER_REGISTER(rte_driver)
     `-  insert into dev_driver_list, rte_driver object

 rte_eal_init():
  |- rte_eal_pci_init()
  |  `- scan and fill pci_device_list from sysfs
  |
  |- rte_eal_dev_init()
  |  `- For each rte_driver in dev_driver_list
  |     `- call the rte_driver->init() function
  |        |- PMDs designed to call rte_eth_driver_register(eth_driver)
  |        |- eth_driver have rte_pci_driver embedded in them
  |        `- rte_eth_driver_register installs the 
  |           rte_pci_driver->devinit/devuninit callbacks.
  |
  |- rte_eal_pci_probe()
  |  |- For each device detected, dev_driver_list is parsed and matching is
  |  |  done.
  |  |- For each matching device, the rte_pci_driver->devinit() is called.
  |  |- Default map is to rte_eth_dev_init() which in turn creates a
  |  |  new ethernet device (eth_dev)
  |  |  `- eth_drv->eth_dev_init() is called which is implemented by 
  `--|    individual PMD drivers.

--

The structure of driver looks something like:

 +------------+     ._____.
 | rte_driver <-----| PMD |___
 |  .init     |     `-----`   \
 +----.-------+      |         \
      `-.            |         What PMD actually is
         \           |          |
          +----------v----+     |
          | eth_driver    |     |
          | .eth_dev_init |     |
          +----.----------+     |
               `-.              |
                  \             |
                   +------------v---+
                   | rte_pci_driver |
                   | .pci_devinit   |
                   +----------------+

  and all devices are part of a following linked lists:
    - dev_driver_list for all rte_drivers
    - pci_device_list for all devices, whether PCI or VDEV


>From the above:
 * a PMD initializes a rte_driver, eth_driver even though actually it is a 
   pci_driver
 * initialization routines are passed from rte_driver->pci_driver->eth_driver
   even though they should ideally be rte_eal_init()->rte_pci_driver()
 * For a single driver/device type model, this is not necessarily a
   functional issue - but more of a design language.
 * But, when number of driver/device type increase, this would create problem
   in how driver<=>device links are represented.

Proposed Architecture:
======================

A nice representation has already been created by David in [3]. Copying that
here:

                +------------------+ +-------------------------------+
                |                  | |                               |
                | rte_pci_device   | | rte_pci_driver                |
                |                  | |                               |
+-------------+ | +--------------+ | | +---------------------------+ |
|             | | |              | | | |                           | |
| rte_eth_dev +---> rte_device   +-----> rte_driver                | |
|             | | |  char name[] | | | |  char name[]              | |
+-------------+ | |              | | | |  int init(rte_device *)   | |
                | +--------------+ | | |  int uninit(rte_device *) | |
                |                  | | |                           | |
                +------------------+ | +---------------------------+ |
                                     |                               |
                                     +-------------------------------+

- for ethdev on top of vdev devices

                +------------------+ +-------------------------------+
                |                  | |                               |
                | drv specific     | | rte_vdev_driver               |
                |                  | |                               |
+-------------+ | +--------------+ | | +---------------------------+ |
|             | | |              | | | |                           | |
| rte_eth_dev +---> rte_device   +-----> rte_driver                | |
|             | | |  char name[] | | | |  char name[]              | |
+-------------+ | |              | | | |  int init(rte_device *)   | |
                | +--------------+ | | |  int uninit(rte_device *) | |
                |                  | | |                           | |
                +------------------+ | +---------------------------+ |
                                     |                               |
                                     |   int priv_size               |
                                     |                               |
                                     +-------------------------------+

Representing from above, it would be:

       `---. <<Inherits>> /                  /
           |\____________/________          /
           |            /         \        /
           +-----------/-----+   +--------/---------+
           | rte_pci_device  |   | rte_xxx_device   |
           |  <dev data>     |   |  <dev data>      |

           +-----------------+   +------------------+

 * Each driver type has its own structure which derives from the generic 
   rte_driver structure.
   \- Each driver type maintains its own list, at the same time, rte_driver
      list also exists - so that *all* drivers can be looped on, if required.
 * Each device, associated with one or more drivers, has its own type
   derived from rte_device
   \- Each device _may_ maintain its own list (for example, in current 
      implementation, vdev is not maintaining it).

==Introducing a new device/driver type implies==
  - creating their own rte_<xxx>.h file which contains the device/driver
    definitions.
  - defining the DRIVER_REGISTER_XXX helpers


==Hotplugging Support==
  - devices should be able to support attach/detach operations.
  - Earlier these functions were part of ethdev. They have been moved to eal
    to be more generic.


About the Patches:
==================

There are a large number of patches for this - primarily because the changes 
are quite varied and keeping them logically separate yet compilable is
important. Most of the patches are small and those which are large touch the
drivers (PMDs) to accommodate the structure changes:

 - Patches 0001~0003 are for introducing the container_of function (so that 
   rte_device can be obtained from rte_pci_device, for example), and 
   removing unused code.
 - Patches 0004~0007 just perform the ground work for enabling change from
   rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
 - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
   including cryptodev, which is eventually generalized with PCI)
 - Patch 0009~0010 merge the crypto and pci functions for registration and 
   naming.
 - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of 
   complete bus and has been generalized into EAl from ethdev.
 - Patches 0015 introduces vdev init/uninit into separate C units and 
   enables its compilation. Patch 0016~0017 build on it and remove the 
   remaining legacy support for vdev/pdev distinctions.
 - Patches 0018~0022 enable the vdev drivers to register using the 
   DRIVER_REGISTER_* operations, and remove their rte_driver->init()
 - Patch 0023 enables the rte_driver registration into a common driver
   linked list.
 - Patches 0024~0025 introduce the rte_device, a generalization of 
   rte_xxx_device, and associated operation of creating rte_device linked 
   list. It also enables the drivers to use rte_device.name/numa_node 
   members rather than rte_xxx_device specific members.

Notes:
======

* Some sign-off were already provided by Jan on the original v5; But, as a 
  large number of merges have been made, I am leaving those out just in case 
  it is not sync with initial understanding.

* This might not be in-sync with pmdinfogen as PMD_REGISTER_DRIVER is
  removed [7].

Changes since v7:
- Rebase over master (e22856313fff2)
- Merge the patch series by David [1][2] and Jan [4] into a single set
  hereafter, PCI and VDEV, both are re-factored for rte_device/driver model

Changes since v6:
- rebase over 16.07 (b0a1419)
- DRIVER_REGISTER_PCI macro is now passed pci_drv rather than drv
- review comments regarding missing information in log messages
- new API additions to 16.11 map objects
- review comment in [5] and [7] are not included in this series.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be in 
  sync
  with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can be merged]
- Modifications to bnxt and thunderx driver PMD registration files for
  using the simplified PCI device registration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port which
  were removed by previous patchset. These are being used by pdump library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

This gives compilation error for mlx5, because the libraries mlx depends
defines same macro:
.../rte_common.h:338:9: error: 'container_of' macro redefined
/usr/include/infiniband/verbs.h:77:9: note: previous definition is here

Does it make sense to protect macro with
#ifndef container_of
...
#endif

OR

add a dpdk prefix?

I thought testing with scripts/test-build.sh and default configuration 
would compile all drivers - I was wrong. I will retest the patches and 
release again.

Is there a better way to test that no driver breaks? Any particular 
parameters I should use for test-build.sh?

I used 'x86_64-native-linuxapp-gcc+default+debug+shared' for all patches.

Yes I suggest to create a file ~/.config/dpdk/devel.config to adapt the
configuration to your system.
Once you have installed the required dependencies, you can make this kind
of configuration:

mlxdep=$root/mlx/mofed-3.3-1.0.0.0
szedep=$root/sze/usr-1.1.4
if echo $DPDK_TARGET | grep -q '^x86_64' ; then
    export DPDK_DEP_ARCHIVE=y
    export DPDK_DEP_ZLIB=y
    export DPDK_DEP_PCAP=y
    export DPDK_DEP_SSL=y
    export DPDK_DEP_MOFED=y
    export DPDK_DEP_SZE=y
    export DPDK_DEP_CFLAGS="-I$mlxdep/include -I$szedep/include"
    export DPDK_DEP_LDFLAGS="-L$mlxdep/lib -L$szedep/lib64 -rpath=$szedep/lib64"
    export AESNI_MULTI_BUFFER_LIB_PATH=$root/aesni/ipsec-043
    export LIBSSO_SNOW3G_PATH=$root/libsso/libsso-snow3g-0.3.1
    export LIBSSO_KASUMI_PATH=$root/libsso/libsso-kasumi-0.3.1
fi

It is a good idea to test also with clang (x86_64-native-linuxapp-clang)
and another arch (e.g. arm64-thunderx-linuxapp-gcc).

What does '$root' here refer to?
I am assuming 'mofed-3.3-1.0.0.0' and 'usr-1.1.4' are part of some 
dependencies that I should be revolving. Is that so?
As of now I don't have much idea about this - I will have a look and 
ping back in case I am stuck.

Thanks. I will try the above.

Before releasing v9, I will do these steps.

It is the directory where I compile the DPDK dependencies.

Yes, download and compile them as explain in the respective guides.

You need to install the packages to resolve these dependencies
(libarchive-dev, libzip-dev, libpcap-dev, libcrypto-dev).

Sounds good - probably would prevent double definition in future if 
someone includes any linux header having similar definition.

Generally the container_of definitions are consistent - that is, they 
would invariably use the offsetof from member. In which case, creating a 
new dpdk_* would only duplicate. Thus, I prefer the #ifndef.

I have converted into a conditional macro in v9.
I still couldn't compile and test mlx* - my environment is still not 
prepared. Though, I can see that this error is not being reported anymore.

[dpdk-dev] [PATCH v8 02/25] eal: remove duplicate function declaration

[Shreyansh Jain]

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

[dpdk-dev] [PATCH v8 03/25] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v8 08/25] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

[dpdk-dev] [PATCH v8 09/25] driver: Remove driver register callbacks for crypto/net

[Shreyansh Jain]

Now that all pdev are pci drivers, we don't need to register crypto and ethdev
drivers through a dedicated channel.

Actually here I was a little confused.
This is part of DPDK_2.2 - an old release. Would removing from an old 
release break compatibility for any system using the new release but 
still adhering to older APIs?
Also, there is the case of this comment [1] from Neil Horman (and 
counter argument [2]) about not removing 
'rte_cryptodev_pmd_driver_register' from map file because there was no 
deprecation notice.

Overall situation is that I have maintained the previous patch of 
'rte_cryptodev_pmd_driver_register' removal but refrained from removing 
new symbol - waiting for a little more clarification.

Is it OK to remove a symbol from an older release without a deprecation 
notice? Or, should a deprecation notice follow this patch?

[dpdk-dev] [PATCH v8 10/25] eal/pci: Helpers for device name parsing/update

[Shreyansh Jain]

- Move rte_eth_dev_create_unique_device_name() from ether/rte_ethdev.c to
  common/include/rte_pci.h as rte_eal_pci_device_name(). Being a common method,
  can be used across crypto/net PCI PMDs.
- Remove crypto specific routine and fallback to common name function.
- Introduce a eal private Update function for PCI device naming.

This function doesn't have any return value. Need to change the @return description.

[dpdk-dev] [PATCH v8 11/25] ethdev: do not scan all pci devices on attach

[Shreyansh Jain]

No need to scan all devices, we only need to update the device being
attached.

[dpdk-dev] [PATCH v8 12/25] eal: add hotplug operations for pci and vdev

[Shreyansh Jain]

Hotplug invocations, which deals with devices, should come from the layer that
already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v8 13/25] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v8 15/25] eal: extract vdev infra

[Shreyansh Jain]

Move all PMD_VDEV-specific code into a separate module and header
file to not polute the generic code anymore. There is now a list
of virtual devices available.

The rte_vdev_driver integrates the original rte_driver inside
(C inheritance). The rte_driver will be however change in the
future to serve as a common base for all other types of drivers.

The existing PMDs (PMD_VDEV) are to be modified later (there is
no change for them at the moment).

Unlike DRIVER_REGISTER_PCI, DRIVER_EXPORT_NAME is not being called on vdev
registration.

[dpdk-dev] [PATCH v8 16/25] eal: Remove PDEV/VDEV unused code

[Shreyansh Jain]

- Remove checks for VDEV from rte_eal_vdev_(init/uninint) as all devices are
  inherently virtual here.
- PDEVs perform PCI specific inits - rte_eal_dev_init() need not call
  rte_driver->init();

[dpdk-dev] [PATCH v8 17/25] drivers: convert PMD_VDEV drivers to use rte_vdev_driver

[Shreyansh Jain]

All PMD_VDEV drivers can now use rte_vdev_driver instead of the
rte_driver (which is embedded in the rte_vdev_driver).

I have updated this in v9. Compilation now seems OK.
(I missed compiling this before v8)

[dpdk-dev] [PATCH v8 18/25] eal: move init/uninit to rte_vdev_driver

[Shreyansh Jain]

These functions are virtual-device specific and they are never called
for any PCI driver (after introducing DRIVER_REGISTER_PCI, there is
no way to do it). All affected drivers are updated.

The prototypes are renamed to rte_vdev_init_t and rte_vdev_uninit_t.

[dpdk-dev] [PATCH v8 19/25] eal: remove PMD_DRIVER_REGISTER and unused pmd_types

[Shreyansh Jain]

- All devices register themselfs by calling a kind of DRIVER_REGISTER_XXX.
  The PMD_REGISTER_DRIVER is not used anymore.
- PMD_VDEV type is also not being used - can be removed from all VDEVs.

Note: PMD_REGISTER_DRIVER usage by PMDINFO tool and its documentation has not
yet been removed.

[dpdk-dev] [PATCH v8 22/25] eal/pci: inherit rte_driver by rte_pci_driver

[Shreyansh Jain]

Remove the 'name' member from rte_pci_driver and move to generic rte_driver.

Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has been
populated into the rte_driver.name member - assignments through eth_driver
has been removed.

bnx2x_rxtx.c also needs to be updated:

Ok - I will fix this. It seems I really need a better way to test before

I have updated this in v9. Compilation is OK now.
(I had missed compiling this before sending v8).

Though I have updated the code here, I have not yet been able to compile 
this because of some dependencies. I am still to setup env for szedata2 
compilation.

There are a few name fields:

1) eth_dev->data->name
2) eth_dev->data->drv_name
3) rte_driver->name
4) dev_info->driver_name


What should be the relation between them?

I guess 1) is device_name, 2, 3, 4 are same thing and driver_name.

If this is correct, virtual drivers needs to be updated for this,
because for them 3 != (2 == 4). They all use global variable for 2 & 4.

And what do you think removing 2) completely?
I guess it exists for virtual devices, since for them eth_driver is not
exists and not able to access to rte_driver->name from eth_dev, but this
is solvable.


Thanks,
ferruh

Yes, (1) is the ethernet device name.
(2), (3) are same, i.e. driver name
(4) is an output field for eth_dev_info_get method and would represent 
same thing as (2) and (3).

Ok. I didn't notice this. I will check it once again.

Ok.
Probably, one way to solve is to make eth_dev->driver point to 
rte_vdev_driver. That way, rte_driver->name would replace 
eth_dev->data->drv_name.
I will give it a thought. Thanks for pointing out.

[dpdk-dev] [PATCH v8 25/25] eal/pci: Create rte_device list and fallback on its members

[Shreyansh Jain]

Now that rte_device is available, drivers can start using its members (numa,
name) as well as link themselves into another rte_device list.

As of now no one is using this list, but can be used for moving over all
devices (pdev/vdev/Xdev) and perform bulk actions (like cleanup).

There are also "eth_driver" and "rte_cryptodev_driver", which can  be
represent as:
+-----------------------------------+
|                                   |
| eth_driver / rte_cryptodev_driver |
|                                   |
| +-------------------------------+ |
| |                               | |
| | rte_pci_driver                | |
| |                               | |
| | +---------------------------+ | |
| | |                           | | |
| | | rte_driver                | | |
| | |  char name[]              | | |
| | |  int init(rte_device *)   | | |
| | |  int uninit(rte_device *) | | |
| | |                           | | |
| | +---------------------------+ | |
| |                               | |
| +-------------------------------+ |
|                                   |
+-----------------------------------+

Is eth_driver really needs to be inherited from rte_pci_driver?
It is possible to have ethernet driver, without PCI bus, at least we
have virtual driver samples.

How about:
+-------------------------------+
|                               |
| rte_pci_driver /              |
|           rte_vdev_driver     |
| +---------------------------+ |      +-------------------+
| |                           | |      | eth_driver        |
| | rte_driver                |<---------- driver          |
| |  char name[]              | |      |   eth_dev_init    |
| |  int init(rte_device *)   | |      |   eth_dev_uninit  |
| |  int uninit(rte_device *) | |      |                   |
| |                           | |      |                   |
| +---------------------------+ |      |                   |
| functional_driver ------------------>|                   |
+-------------------------------+      +-------------------+

Currently there is no way to reference rte_vdev_driver from eth_driver,
since it only has pci_drv field.

With this update, it can be possible to create eth_driver and
rte_eth_vdev_probe() for virtual drivers for example. (Although this may
not necessary right now, this gives ability to do.)



Another think, what do you think moving "dev_private_size" from
eth_driver and rte_cryptodev_driver to rte_driver, since this looks like
generic need for drivers.



And last think, what do you think renaming eth_driver to rte_eth_driver
to be consistent?

I agree with this. There would be cases where even non-PCI devices are 
ethernet devices. As of now, in the proposed patchset, rte_soc_driver 
has been added into this but it is not a scalable solution. We cannot go 
on and add all type of devices into this.

Having said this, back reference to type of ethernet device would be 
important if the ethernet driver needs to refer to some hardware 
specific information as part of rte_xxx_driver.

Even while I was re-creating this patchset I was wondering how to 
realign the eth_driver<=>rte_eth_dev (even naming is inconsistent) with 
rte_*_driver/device and rte_driver/device.
I agree with you that we should link eth_driver->rte_driver.

My only concern being a case where a PCI (or other) based ethernet 
device needs access to driver structure for some info. Is that even a 
possible usecase?

True.

Agree with you. This change can help various other similar cases.

I don't see any problem in this as well.

Yes, I think it should have been a most basic patch - 
eth_driver<->rte_eth_dev combination has existed too long.

In the v9 that I have posted, above changes have not been incorporated 
yet. All the above changes are dependent on one change: to introduce 
rte_driver<->eth_driver relationship:

  --------------------+ <is type of>
  eth_driver (PMD)    |-------------> rte_driver
  crypto_driver (PMD) |               ^
  <more in future>    |               |
  --------------------+               | <inherits>
                                     /
            +-----------------------/+
            | rte_pci_driver         |
            | rte_vdev_driver        |
            | rte_soc_driver         |
            | rte_xxx_driver         |

If I go ahead with above model, PMDs would now have to define 
rte_driver, rte_pci_driver and eth_driver. As of now, PMDs only define a 
eth_driver and embed pci_driver into it. This change makes the current 
patch quite large - which is one of the primary reasons I postponed it 
for another patchset/phase.

Further, now that eth_driver no longer embeds rte_pci_driver, it becomes 
unused in the PMDs - it was only being used to access the init fns. I am 
still to find a way around this - whether to completely do away with it 
or have some macro attach it to another list.

I will work on this and post another RFC style series based on current 
rte_driver/device so as to take more inputs.

Hi Shreyansh,

I am sorry to be quiet on this thread. I am traveling in those
two weeks and have some vacation. However, I passively follow the
conversation. Thank you for your work so far!

> There are a large number of patches for this - primarily because the changes

>    removing unused code.
>  - Patches 0004~0007 just perform the ground work for enabling change from
>    rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
>  - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
>    including cryptodev, which is eventually generalized with PCI)
>  - Patch 0009~0010 merge the crypto and pci functions for registration and 
>    naming.
>  - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of 
>    complete bus and has been generalized into EAl from ethdev.
>  - Patches 0015 introduces vdev init/uninit into separate C units and 
>    enables its compilation. Patch 0016~0017 build on it and remove the 
>    remaining legacy support for vdev/pdev distinctions.
>  - Patches 0018~0022 enable the vdev drivers to register using the 
>    DRIVER_REGISTER_* operations, and remove their rte_driver->init()
>  - Patch 0023 enables the rte_driver registration into a common driver
>    linked list.
>  - Patches 0024~0025 introduce the rte_device, a generalization of

> >
> > There are a large number of patches for this - primarily because the changes

> > important. Most of the patches are small and those which are large touch the
> > drivers (PMDs) to accommodate the structure changes:
> >
> >  - Patches 0001~0003 are for introducing the container_of function (so that
> >    rte_device can be obtained from rte_pci_device, for example), and
> >    removing unused code.
> >  - Patches 0004~0007 just perform the ground work for enabling change from
> >    rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
> >  - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
> >    including cryptodev, which is eventually generalized with PCI)
> >  - Patch 0009~0010 merge the crypto and pci functions for registration and
> >    naming.
> >  - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of
> >    complete bus and has been generalized into EAl from ethdev.
> >  - Patches 0015 introduces vdev init/uninit into separate C units and
> >    enables its compilation. Patch 0016~0017 build on it and remove the
> >    remaining legacy support for vdev/pdev distinctions.
> >  - Patches 0018~0022 enable the vdev drivers to register using the
> >    DRIVER_REGISTER_* operations, and remove their rte_driver->init()
> >  - Patch 0023 enables the rte_driver registration into a common driver
> >    linked list.
> >  - Patches 0024~0025 introduce the rte_device, a generalization of
> >    rte_xxx_device, and associated operation of creating rte_device linked
> >    list. It also enables the drivers to use rte_device.name/numa_node
> >    members rather than rte_xxx_device specific members.

[dpdk-dev] [PATCH v9 00/25] Introducing rte_driver/rte_device generalization

[Shreyansh Jain]

Based on master (e22856313)

Background:
===========

It includes two different patch-sets floated on ML earlier:
 * Original patch series is from David Marchand [1], [2].
  `- This focused mainly on PCI (PDEV) part
  `- v7 of this was posted by me [8] in August/2016
 * Patch series [4] from Jan Viktorin
  `- This focused on VDEV and rte_device integration

Introduction:
=============

This patch series introduces a generic device model, moving away from PCI 
centric code layout. Key change is to introduce rte_driver/rte_device 
structures at the top level which are inherited by 
rte_XXX_driver/rte_XXX_device - where XXX belongs to {pci, vdev, soc (in 
future),...}.

Key motivation for this series is to move away from PCI centric design of 
EAL to a more hierarchical device model - pivoted around a generic driver 
and device. Each specific driver and device can inherit the common 
properties of the generic set and build upon it through driver/device 
specific functions.

Earlier, the EAL device initialization model was:
(Refer: [3])

--
 Constructor:
  |- PMD_DRIVER_REGISTER(rte_driver)
     `-  insert into dev_driver_list, rte_driver object

 rte_eal_init():
  |- rte_eal_pci_init()
  |  `- scan and fill pci_device_list from sysfs
  |
  |- rte_eal_dev_init()
  |  `- For each rte_driver in dev_driver_list
  |     `- call the rte_driver->init() function
  |        |- PMDs designed to call rte_eth_driver_register(eth_driver)
  |        |- eth_driver have rte_pci_driver embedded in them
  |        `- rte_eth_driver_register installs the 
  |           rte_pci_driver->devinit/devuninit callbacks.
  |
  |- rte_eal_pci_probe()
  |  |- For each device detected, dev_driver_list is parsed and matching is
  |  |  done.
  |  |- For each matching device, the rte_pci_driver->devinit() is called.
  |  |- Default map is to rte_eth_dev_init() which in turn creates a
  |  |  new ethernet device (eth_dev)
  |  |  `- eth_drv->eth_dev_init() is called which is implemented by 
  `--|    individual PMD drivers.

--

The structure of driver looks something like:

 +------------+     ._____.
 | rte_driver <-----| PMD |___
 |  .init     |     `-----`   \
 +----.-------+      |         \
      `-.            |         What PMD actually is
         \           |          |
          +----------v----+     |
          | eth_driver    |     |
          | .eth_dev_init |     |
          +----.----------+     |
               `-.              |
                  \             |
                   +------------v---+
                   | rte_pci_driver |
                   | .pci_devinit   |
                   +----------------+

  and all devices are part of a following linked lists:
    - dev_driver_list for all rte_drivers
    - pci_device_list for all devices, whether PCI or VDEV


>From the above:
 * a PMD initializes a rte_driver, eth_driver even though actually it is a 
   pci_driver
 * initialization routines are passed from rte_driver->pci_driver->eth_driver
   even though they should ideally be rte_eal_init()->rte_pci_driver()
 * For a single driver/device type model, this is not necessarily a
   functional issue - but more of a design language.
 * But, when number of driver/device type increase, this would create problem
   in how driver<=>device links are represented.

 * Each driver type has its own structure which derives from the generic 
   rte_driver structure.
   \- Each driver type maintains its own list, at the same time, rte_driver
      list also exists - so that *all* drivers can be looped on, if required.
 * Each device, associated with one or more drivers, has its own type
   derived from rte_device
   \- Each device _may_ maintain its own list (for example, in current 
      implementation, vdev is not maintaining it).

==Introducing a new device/driver type implies==
  - creating their own rte_<xxx>.h file which contains the device/driver
    definitions.
  - defining the DRIVER_REGISTER_XXX helpers

==Hotplugging Support==
  - devices should be able to support attach/detach operations.
  - Earlier these functions were part of ethdev. They have been moved to eal
    to be more generic.

 This patch is part of larger aim to:

 --------------------+ <is type of>
 eth_driver (PMD)    |-------------> rte_driver
 crypto_driver (PMD) |               ^
 <more in future>    |               |
 --------------------+               | <inherits>
                                    /
           +-----------------------/+
           | rte_pci_driver         |
           | rte_vdev_driver        |
           | rte_soc_driver         |
           | rte_xxx_driver         |

 Where PMD devices (rte_eth_dev, rte_cryptodev_dev) are connected to their
 drivers rather than explicitly inheriting type specific driver (PCI, etc).


About the Patches:
==================

There are a large number of patches for this - primarily because the changes 
are quite varied and keeping them logically separate yet compilable is
important. Most of the patches are small and those which are large touch the
drivers (PMDs) to accommodate the structure changes:

 - Patches 0001~0003 are for introducing the container_of function (so that 
   rte_device can be obtained from rte_pci_device, for example), and 
   removing unused code.
 - Patches 0004~0007 just perform the ground work for enabling change from
   rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
 - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
   including cryptodev, which is eventually generalized with PCI)
 - Patch 0009~0010 merge the crypto and pci functions for registration and 
   naming.
 - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of 
   complete bus and has been generalized into EAl from ethdev.
 - Patches 0015 introduces vdev init/uninit into separate C units and 
   enables its compilation. Patch 0016~0017 build on it and remove the 
   remaining legacy support for vdev/pdev distinctions.
 - Patches 0018~0022 enable the vdev drivers to register using the 
   DRIVER_REGISTER_* operations, and remove their rte_driver->init()
 - Patch 0023 enables the rte_driver registration into a common driver
   linked list.
 - Patches 0024~0025 introduce the rte_device, a generalization of 
   rte_xxx_device, and associated operation of creating rte_device linked 
   list. It also enables the drivers to use rte_device.name/numa_node 
   members rather than rte_xxx_device specific members.

Notes:
======

* Some sign-off were already provided by Jan on the original v5; But, as a 
  large number of merges have been made, I am leaving those out just in case 
  it is not sync with initial understanding.

* This might not be in-sync with pmdinfogen as PMD_REGISTER_DRIVER is
  removed [7].

Future Work/Pending:
===================
 - Presently eth_driver, rte_eth_dev are not aligned to the rte_driver/
   rte_device model. eth_driver still is a PCI specific entity. This
   has been highlighted by comments from Ferruh in [9].
 - cryptodev driver too still remains to be normalized over the rte_driver
   model
 - Some variables, like drv_name (as highlighted by Ferruh), are getting
   duplicated across rte_xxx_driver/device and rte_driver/device.

Changes since v8:
- Some review comments from Ferruh Yigit & Reshma Pattan have been fixed.
 = Though changes in mlx4/mlx5/szedata2 have been done, I am still unable to
   verify those in absence of a proper environment at my end.
 = Comment from Ferruh for eth_driver, drv_name are not fixed yet.
- Added a 'Future work' section in Covering letter

Changes since v7:
- Rebase over master (e22856313fff2)
- Merge the patch series by David [1][2] and Jan [4] into a single set
  hereafter, PCI and VDEV, both are re-factored for rte_device/driver model

Changes since v6:
- rebase over 16.07 (b0a1419)
- DRIVER_REGISTER_PCI macro is now passed pci_drv rather than drv
- review comments regarding missing information in log messages
- new API additions to 16.11 map objects
- review comment in [5] and [7] are not included in this series.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be in 
  sync
  with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can be merged]
- Modifications to bnxt and thunderx driver PMD registration files for
  using the simplified PCI device registration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port which
  were removed by previous patchset. These are being used by pdump library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

Some mlx5 files includes dpdk version of container_of first, they
produce following warning:

In file included from .../dpdk/build/include/rte_mbuf.h:57:0,
                 from .../dpdk/build/include/rte_ether.h:52,
                 from .../dpdk/drivers/net/mlx5/mlx5_trigger.c:38:

.../dpdk/build/include/rte_common.h:343:14: warning: cast discards
‘const’ qualifier from pointer target type [-Wcast-qual]
  ((type *) (((char *) (p)) - offsetof(type, member)))

The verbs.h version of container_of is same with dpdk one, I am not able
to find why one gives warning but other not.

This warning is a known issue in the Verbs header that will be addressed
eventually. It occurs even without Shreyansh's patch (more likely when
CONFIG_RTE_LIBRTE_MLX4_DEBUG and/or CONFIG_RTE_LIBRTE_MLX5_DEBUG are
enabled).

Your container_of() macro is fine, no need to spend time on this.

[dpdk-dev] [PATCH v9 02/25] eal: remove duplicate function declaration

[Shreyansh Jain]

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

Fixes: e57f20e05177 ("eal: make vdev init path generic for both virtual and pci devices")

[dpdk-dev] [PATCH v9 03/25] pci: no need for dynamic tailq init

[Shreyansh Jain]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v9 06/25] eal: introduce init macros

[Shreyansh Jain]

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
DRIVER_REGISTER_PCI is added as a helper for pci drivers.

I would keep in the commit log a mention on the 1 - 1 association
between the ethdev/crypto device and the pci device.

Besides, I kind of remember a suggestion to rename init as probe and
uninit as remove (Thomas ?).
But this can go later in the series.

[dpdk-dev] [PATCH v9 08/25] drivers: convert all pdev drivers as pci drivers

[Shreyansh Jain]

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

[Shreyansh Jain]

Now that all pdev are pci drivers, we don't need to register crypto and ethdev
drivers through a dedicated channel.

[dpdk-dev] [PATCH v9 10/25] eal/pci: Helpers for device name parsing/update

[Shreyansh Jain]

- Move rte_eth_dev_create_unique_device_name() from ether/rte_ethdev.c to
  common/include/rte_pci.h as rte_eal_pci_device_name(). Being a common method,
  can be used across crypto/net PCI PMDs.
- Remove crypto specific routine and fallback to common name function.
- Introduce a eal private Update function for PCI device naming.

[dpdk-dev] [PATCH v9 12/25] eal: add hotplug operations for pci and vdev

[Shreyansh Jain]

Hotplug invocations, which deals with devices, should come from the layer that
already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v9 13/25] ethdev: convert to eal hotplug

[Shreyansh Jain]

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some mechanism
to inform applications of port creation/removal to substitute for ethdev
hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the following
commit.

[dpdk-dev] [PATCH v9 14/25] ethdev: get rid of device type

[Shreyansh Jain]

Now that hotplug has been moved to eal, there is no reason to keep the device
type in this layer.

[dpdk-dev] [PATCH v9 15/25] eal: extract vdev infra

[Shreyansh Jain]

Move all PMD_VDEV-specific code into a separate module and header
file to not polute the generic code anymore. There is now a list
of virtual devices available.

The rte_vdev_driver integrates the original rte_driver inside
(C inheritance). The rte_driver will be however change in the
future to serve as a common base for all other types of drivers.

The existing PMDs (PMD_VDEV) are to be modified later (there is
no change for them at the moment).

Unlike DRIVER_REGISTER_PCI, DRIVER_EXPORT_NAME is not being called on vdev
registration.

[dpdk-dev] [PATCH v9 16/25] eal: Remove PDEV/VDEV unused code

[Shreyansh Jain]

- Remove checks for VDEV from rte_eal_vdev_(init/uninint) as all devices are
  inherently virtual here.
- PDEVs perform PCI specific inits - rte_eal_dev_init() need not call
  rte_driver->init();

[dpdk-dev] [PATCH v9 17/25] drivers: convert PMD_VDEV drivers to use rte_vdev_driver

[Shreyansh Jain]

All PMD_VDEV drivers can now use rte_vdev_driver instead of the
rte_driver (which is embedded in the rte_vdev_driver).

Thanks!
I think this is similar to what Ferruh has commented in [1]. I missed 
adding these functions to the map file in the 16th patch which is why 
shared library is failing. I have noted that for change in v10 as and 
when that is ready.

[dpdk-dev] [PATCH v9 18/25] eal: move init/uninit to rte_vdev_driver

[Shreyansh Jain]

These functions are virtual-device specific and they are never called
for any PCI driver (after introducing DRIVER_REGISTER_PCI, there is
no way to do it). All affected drivers are updated.

The prototypes are renamed to rte_vdev_init_t and rte_vdev_uninit_t.

[dpdk-dev] [PATCH v9 19/25] eal: remove PMD_DRIVER_REGISTER and unused pmd_types

[Shreyansh Jain]

- All devices register themselfs by calling a kind of DRIVER_REGISTER_XXX.
  The PMD_REGISTER_DRIVER is not used anymore.
- PMD_VDEV type is also not being used - can be removed from all VDEVs.

Note: PMD_REGISTER_DRIVER usage by PMDINFO tool and its documentation has not
yet been removed.

[dpdk-dev] [PATCH v9 22/25] eal/pci: inherit rte_driver by rte_pci_driver

[Shreyansh Jain]

Remove the 'name' member from rte_pci_driver and move to generic rte_driver.

Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has been
populated into the rte_driver.name member - assignments through eth_driver
has been removed.

This needs to be part of patch 15, where these functions implemented.

Missing these in .map files cause patch 17,18,19,20,21 fail to compile
for shared lib config.

[dpdk-dev] [PATCH v9 25/25] eal/pci: Create rte_device list and fallback on its members

[Shreyansh Jain]

Now that rte_device is available, drivers can start using its members (numa,
name) as well as link themselves into another rte_device list.

As of now no one is using this list, but can be used for moving over all
devices (pdev/vdev/Xdev) and perform bulk actions (like cleanup).

Overall I like to see the clean separation.
Are you sure you removed as much as possible from PCI?
I wonder of global PCI device list is needed at all if you now have list of all devices.

>> About the Patches:
>> ==================
>>
>> There are a large number of patches for this - primarily because the changes
>> are quite varied and keeping them logically separate yet compilable is
>> important. Most of the patches are small and those which are large touch the
>> drivers (PMDs) to accommodate the structure changes:
>>
>>  - Patches 0001~0003 are for introducing the container_of function (so that
>>    rte_device can be obtained from rte_pci_device, for example), and
>>    removing unused code.
>>  - Patches 0004~0007 just perform the ground work for enabling change from
>>    rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
>>  - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
>>    including cryptodev, which is eventually generalized with PCI)
>>  - Patch 0009~0010 merge the crypto and pci functions for registration and
>>    naming.
>>  - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of
>>    complete bus and has been generalized into EAl from ethdev.
>>  - Patches 0015 introduces vdev init/uninit into separate C units and
>>    enables its compilation. Patch 0016~0017 build on it and remove the
>>    remaining legacy support for vdev/pdev distinctions.
>>  - Patches 0018~0022 enable the vdev drivers to register using the
>>    DRIVER_REGISTER_* operations, and remove their rte_driver->init()
>>  - Patch 0023 enables the rte_driver registration into a common driver
>>    linked list.
>>  - Patches 0024~0025 introduce the rte_device, a generalization of
>>    rte_xxx_device, and associated operation of creating rte_device linked
>>    list. It also enables the drivers to use rte_device.name/numa_node
>>    members rather than rte_xxx_device specific members.

>> Future Work/Pending:
>> ===================
>>  - Presently eth_driver, rte_eth_dev are not aligned to the rte_driver/
>>    rte_device model. eth_driver still is a PCI specific entity. This
>>    has been highlighted by comments from Ferruh in [9].

I am not very sure of what you mean.

If you are referring to whether all PCI PMDs have been taken care of, I 
think they are. Only issue being I can't test all of them functionally. 
I have some steps provided by Thomas which can help me compile test these.

Or, if you are referring to whether PCI drivers have been completely 
disconnected from existing EAL (and converted to above linkage), I think 
yes.

Key change that still remains is delinking eth_driver from PCI type and 
using a more generic approach where eth_driver (or rte_eth_driver, after 
name change) can be of any type - PCI, Virtual, SoC etc.

I think yes. There are separate lists for all device types which helps 
keep the EAL code free of type checks. But, functionally it doesn't make 
that big a different between a common or specific list.
I am in favor of separate lists of each rte_xxx_device/driver type - 
other than a global list (which is not actually being used, for now).

I was just concerned that doing bookkeeping on multiple lists creates more possibilities
for bugs where error unwind paths don't match.

That is true.
But in this particular situation (in my opinion), maintaining multiple 
lists helps because:

1. Device/Drivers lists are separate and no functionality except setup 
and tear-down operation would ever need to parse the common list - at 
least not during the application run-to-completion-cycle.

2. Keeping them separate helps make the respective scan/probe code 
cleaner. In fact, in absence of checks for device type, I think 
debugging would be easier as one would only need to focus on code 
related to attached physical/virtual device.

But again, above is just my opinion and preference - if merging the 
lists helps, it can be done. In fact, rte_driver/rte_device are already 
creating a common list - just that it is not being used right now.

I don't think there is any technical impact of this (except increasing 
type validation - but that is only in setup/tear-down path).

Hey Shreyansh,

I got some time over the last couple of days to got through this 
patchset and your soc changes, and it's really a great clean up of the 
driver and device infrastructure code.

I guess I'm coming to this party a bit late but I have some thoughts on 
the the object model that you've outlined it improves things a huge 
amount but I wonder does it go far enough.

I think that currently the coupling of the rte_driver to instances of 
rte_pci_driver, rte_vdev_driver etc still really clouds the abstraction. 
I think if we introduced a rte_bus and rte_bus_data abstractions with 
all rte_drivers having a rte_bus instance then we could further simplify 
the driver and device management, I think this would greatly reduce the 
number of driver/device APIs in the EAL as I think most bus 
functionality could be abstracted into a simpler API. This would also 
make it possible to create new driver and device types and allowing them 
to be plug-able components into DPDK and which I don't think would work 
currently even  with the changes included here.

http://imgur.com/a/3b7XM

The link above is to a png of a visio which outlines the object model 
that I'm thinking of. The main extension from your current patchset 
would be that rte_eth_driver and rte_crypto_driver would now always be 
inheriting from rte_driver and not rte_soc_driver/rte_pci_driver, etv 
but the rte_driver object would have rte_bus instance which could be of 
type rte_bus_pci/ rte_bus_virtual/ rte_bus_soc etc.  This I think would 
allow the EAL to be written in such a way that it only every operates on 
the base object types rte_device/rte_driver directly never the 
derivative objects, like the rte_vdev_driver, rte_pci_driver. Also I 
prefer the abstraction that a driver has a bus rather than it is the 
bus. Also I think would be the devices layer to written driver/bus 
agnostic, so the eth_dev layer shouldn't know if and underlying PMD is 
PCI/memory based or virtual. Only the poll mode driver itself, and the 
part of the EAL which manages driver initialization should have 
knowledge of the drivers bus type.

Anyway have a look, and let me know what you think.

Thanks
Declan

Thank you.
Honestly speaking, I am more of an intermediate maintainer - most of the 
work was already done by David/Jan.

This is where I beg to differ. rte_driver is actually a representation 
of a generic bus on which devices (PCI/XXX) would be attached.
Creating one more abstraction of rte_bus* would create new boundaries of 
what each structure does. At least as of now I couldn't think of why the 
functions you have mentioned below cannot be handled by 
rte_driver/device - Or, to put it other way, what differentiates an 
abstracted rte_driver/device with rte_bus*.

I saw the image. Key difference I see is that now mapping becomes 
responsibility of a bus. Other than that, what else do you propose would 
a 'rte_bus' equivalent do? Any example from current model or PMDs?

In fact, already rte_driver itself doesn't have much to do except 
init/uninit (which too is pending) and some state vars.

I agree to your points that EAL should operate on base class 
rte_driver/device. But, I am still not clear how a bus would add value 
to this model of rte_device<=>rte_pci_device/rte_driver<=>rte_pci_driver 
(PCI as example). Can you explain with some example case where this new 
layer would help us?

Overall I feel that we are on same page except the new class for Bus 
introduced in your proposal. In my opinion at least as of this first 
draft proposal keeping things simpler might be better. We can always 
come back and introduce this new abstraction in subsequent versions - it 
looks incremental to me.

And, probably other members on list might have a better view of this 
abstraction. I am open to discussion.

Overall, we are still missing some parts :
- in my initial proposition, the rte_driver would embed the
probe/remove (previsouly init/uninit) functions that would take
rte_device object as arguments (and maybe we should get rid of the
double lists, I am not yet convinced it is easy).
- the pmdinfo stuff is broken and could be implemented for vdev, I did
a quick patch that replaces the "PMD_REGISTER_DRIVER(.*)" regexp as
"DRIVER_REGISTER_.*(.*)" then I added a DRIVER_EXPORT_NAME(nm,
__COUNTER__) in the vdev register macro, it looks to work fine.
pmdinfo is a bit too pci but I think we can go with this.
- the names should go to rte_device/rte_driver objects ?

[dpdk-dev] [PATCH v10 00/25] Introducing rte_driver/rte_device generalization

[Shreyansh Jain]

Based on master (58efd680d5e)

Background:
===========

It includes two different patch-sets floated on ML earlier:
 * Original patch series is from David Marchand [1], [2].
  `- This focused mainly on PCI (PDEV) part
  `- v7 of this was posted by me [8] in August/2016
 * Patch series [4] from Jan Viktorin
  `- This focused on VDEV and rte_device integration

Introduction:
=============

This patch series introduces a generic device model, moving away from PCI 
centric code layout. Key change is to introduce rte_driver/rte_device 
structures at the top level which are inherited by 
rte_XXX_driver/rte_XXX_device - where XXX belongs to {pci, vdev, soc (in 
future),...}.

Key motivation for this series is to move away from PCI centric design of 
EAL to a more hierarchical device model - pivoted around a generic driver 
and device. Each specific driver and device can inherit the common 
properties of the generic set and build upon it through driver/device 
specific functions.

Earlier, the EAL device initialization model was:
(Refer: [3])

--
 Constructor:
  |- PMD_DRIVER_REGISTER(rte_driver)
     `-  insert into dev_driver_list, rte_driver object

 rte_eal_init():
  |- rte_eal_pci_init()
  |  `- scan and fill pci_device_list from sysfs
  |
  |- rte_eal_dev_init()
  |  `- For each rte_driver in dev_driver_list
  |     `- call the rte_driver->init() function
  |        |- PMDs designed to call rte_eth_driver_register(eth_driver)
  |        |- eth_driver have rte_pci_driver embedded in them
  |        `- rte_eth_driver_register installs the 
  |           rte_pci_driver->devinit/devuninit callbacks.
  |
  |- rte_eal_pci_probe()
  |  |- For each device detected, dev_driver_list is parsed and matching is
  |  |  done.
  |  |- For each matching device, the rte_pci_driver->devinit() is called.
  |  |- Default map is to rte_eth_dev_init() which in turn creates a
  |  |  new ethernet device (eth_dev)
  |  |  `- eth_drv->eth_dev_init() is called which is implemented by 
  `--|    individual PMD drivers.

--

The structure of driver looks something like:

 +------------+     ._____.
 | rte_driver <-----| PMD |___
 |  .init     |     `-----`   \
 +----.-------+      |         \
      `-.            |         What PMD actually is
         \           |          |
          +----------v----+     |
          | eth_driver    |     |
          | .eth_dev_init |     |
          +----.----------+     |
               `-.              |
                  \             |
                   +------------v---+
                   | rte_pci_driver |
                   | .pci_devinit   |
                   +----------------+

  and all devices are part of a following linked lists:
    - dev_driver_list for all rte_drivers
    - pci_device_list for all devices, whether PCI or VDEV


>From the above:
 * a PMD initializes a rte_driver, eth_driver even though actually it is a 
   pci_driver
 * initialization routines are passed from rte_driver->pci_driver->eth_driver
   even though they should ideally be rte_eal_init()->rte_pci_driver()
 * For a single driver/device type model, this is not necessarily a
   functional issue - but more of a design language.
 * But, when number of driver/device type increase, this would create
   problem in how driver<=>device links are represented.

Proposed Architecture:
======================

A nice representation has already been created by David in [3]. Copying that

                |                  | |                               |

 * Each driver type has its own structure which derives from the generic 
   rte_driver structure.
   \- Each driver type maintains its own list, at the same time, rte_driver
      list also exists - so that *all* drivers can be looped on, if required.
 * Each device, associated with one or more drivers, has its own type
   derived from rte_device
   \- Each device _may_ maintain its own list (for example, in current 
      implementation, vdev is not maintaining it).

==Introducing a new device/driver type implies==
  - creating their own rte_<xxx>.h file which contains the device/driver
    definitions.
  - defining the DRIVER_REGISTER_XXX helpers

==Hotplugging Support==
  - devices should be able to support attach/detach operations.
  - Earlier these functions were part of ethdev. They have been moved to eal
    to be more generic.

 This patch is part of larger aim to:

 --------------------+ <is type of>
 eth_driver (PMD)    |-------------> rte_driver
 crypto_driver (PMD) |               ^
 <more in future>    |               |
 --------------------+               | <inherits>
                                    /
           +-----------------------/+
           | rte_pci_driver         |
           | rte_vdev_driver        |
           | rte_soc_driver         |
           | rte_xxx_driver         |

 Where PMD devices (rte_eth_dev, rte_cryptodev_dev) are connected to their
 drivers rather than explicitly inheriting type specific driver (PCI, etc).


About the Patches:
==================

There are a large number of patches for this - primarily because the changes 
are quite varied and keeping them logically separate yet compilable is
important. Most of the patches are small and those which are large touch the
drivers (PMDs) to accommodate the structure changes:

 - Patches 0001~0003 are for introducing the container_of function (so that 
   rte_device can be obtained from rte_pci_device, for example), and 
   removing unused code.
 - Patch 0004 converts the PCI devinit/devuninit method names to probe/
   remove and correspondingly updates all drivers where impact it. VDEV
   based init/uninit have not been modified.
 - Patches 0005~0007 just perform the ground work for enabling change from
   rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
 - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
   including cryptodev, which is eventually generalized with PCI)
 - Patch 0009~0010 merge the crypto and pci functions for registration and 
   naming.
 - Patches 0011~0014 deal with hotplugging - hotplug no more invokes scan of 
   complete bus and has been generalized into EAl from ethdev.
 - Patches 0015 introduces vdev init/uninit into separate C units and 
   enables its compilation. Patch 0016~0017 build on it and remove the 
   remaining legacy support for vdev/pdev distinctions.
 - Patches 0018~0022 enable the vdev drivers to register using the 
   DRIVER_REGISTER_* operations, and remove their rte_driver->init()
 - Patch 0023 enables the rte_driver registration into a common driver
   linked list.
 - Patches 0024~0025 introduce the rte_device, a generalization of 
   rte_xxx_device, and associated operation of creating rte_device linked 
   list. It also enables the drivers to use rte_device.name/numa_node 
   members rather than rte_xxx_device specific members.

Future Work/Pending:
===================
 - Presently eth_driver, rte_eth_dev are not aligned to the rte_driver/
   rte_device model. eth_driver still is a PCI specific entity. This
   has been highlighted by comments from Ferruh in [9].
 - Some variables, like drv_name (as highlighted by Ferruh), are getting
   duplicated across rte_xxx_driver/device and rte_driver/device.

Changes since v9:
- Rebased over master (58efd680d5e)
- Fix issues reported by checkpatch and check-git-log, including changing
  headline of the patches to adhere to these scripts.
- Corrected the patch author field
- Renamed devinit/devuninit for pci_driver to probe/remove as per
  suggestion from David
- Fix for PMD Info gen tool using patch from David
- Fixed review comments [R1], some part of [R2], [R3] using patch from
  David, [R4], [R5] and some inputs from [R6].

Changes since v8:
- Some review comments from Ferruh Yigit & Reshma Pattan have been fixed.
 = Though changes in mlx4/mlx5/szedata2 have been done, I am still unable
   to verify those in absence of a proper environment at my end.
 = Comment from Ferruh for eth_driver, drv_name are not fixed yet.
- Added a 'Future work' section in Covering letter

Changes since v7:
- Rebase over master (e22856313fff2)
- Merge the patch series by David [1][2] and Jan [4] into a single set
  hereafter, PCI and VDEV, both are re-factored for rte_device/driver
  model

Changes since v6:
- rebase over 16.07 (b0a1419)
- DRIVER_REGISTER_PCI macro is now passed pci_drv rather than drv
- review comments regarding missing information in log messages
- new API additions to 16.11 map objects
- review comment in [5] and [7] are not included in this series.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be
  in sync with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can
  be merged]

  using the simplified PCI device registration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port
  which were removed by previous patchset. These are being used by pdump
  library

Changes since v3:

- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug

[dpdk-dev] [PATCH v10 02/25] eal: remove duplicate function declaration

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

Fixes: e57f20e05177 ("eal: make vdev init path generic for both virtual and pci devices")

[dpdk-dev] [PATCH v10 03/25] pci: no need for dynamic tailq init

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v10 04/25] eal/pci: replace PCI devinit/devuninit with probe/remove

[Shreyansh Jain]

Probe and Remove are more appropriate names for PCI init and uninint
operations. This is a cosmetic change.

Only MLX* uses the PCI direct registeration, bypassing PMD_* macro. The
calls backs for this too have been updated.

VDEV are left out. For them, init/uninit are more appropriate.

[dpdk-dev] [PATCH v10 07/25] eal: introduce PCI device init macros

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
DRIVER_REGISTER_PCI is added as a helper for pci drivers.

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

crypto and ethdev drivers aligned to PCI probe/remove. These wrappers are
mapped directly to PCI resources.
Existing handlers for init/uninit can be easily reused for this.

[dpdk-dev] [PATCH v10 09/25] drivers: convert all phy drivers as PCI drivers

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

Signed-off-by: David Marchand <david.marchand@6wind.com>
Signed-off-by: Shreyansh Jain <shreyansh.jain@nxp.com>
---
Changes since v9:
 - Add DRIVER_EXPORT_NAME to DRIVER_REGISTER_PCI
 - For mlx4/mlx5/virtio_ethdev, use DRIVER_EXPORT_NAME directly as they
   don't use DRIVER_REGISTER_PCI
 - Modify PMDINFO matching from PMD_REGISTER_* to DRIVER_REGISTER_*
 All changes above suggested by David Marchand <david.marchand@6wind.com>
 - Change PCI devinit/devuninit to prove/remove

[dpdk-dev] [PATCH v10 10/25] drivers: remove driver register callbacks for crypto/net

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Now that all pdev are pci drivers, we don't need to register crypto and
ethdev drivers through a dedicated channel.

[dpdk-dev] [PATCH v10 11/25] eal/pci: helpers for device name parsing/update

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

- Move rte_eth_dev_create_unique_device_name() from ether/rte_ethdev.c to
  common/include/rte_pci.h as rte_eal_pci_device_name(). Being a common
  method, can be used across crypto/net PCI PMDs.
- Remove crypto specific routine and fallback to common name function.
- Introduce a eal private Update function for PCI device naming.

Earlier device names were created in the format "bus:deviceid.function" as per the below ethdev API.
Now after above new eal API the name format is "domain:bus:deviceid.func" was that intentional  and why is that so.

Yes, this is intentional.
It is to bring the naming in sync with the device name being used for 
scanning on the bus (/sys/bus/pci/devices/AAAA:BB:CC.D/).
Also, it was proposed in a separate patch [1] but merged in this series.

[1] http://dpdk.org/ml/archives/dev/2016-July/044614.html

(Just as a note: I am not the original author of this patch but above is 
what I understood and acked it).

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Hotplug invocations, which deals with devices, should come from the layer
that already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v10 14/25] ethdev: convert to EAL hotplug

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some
mechanism to inform applications of port creation/removal to substitute
for ethdev hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the
following commit.

[dpdk-dev] [PATCH v10 16/25] eal: extract vdev infra

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Move all PMD_VDEV-specific code into a separate module and header
file to not polute the generic code anymore. There is now a list
of virtual devices available.

The rte_vdev_driver integrates the original rte_driver inside
(C inheritance). The rte_driver will be however change in the
future to serve as a common base for all other types of drivers.

The existing PMDs (PMD_VDEV) are to be modified later (there is
no change for them at the moment).

Unlike DRIVER_REGISTER_PCI, DRIVER_EXPORT_NAME is not being called on vdev
registration.

Signed-off-by: Jan Viktorin <viktorin@rehivetech.com>
Signed-off-by: Shreyansh Jain <shreyansh.jain@nxp.com>

Changes since v9:
 - Add DRIVER_EXPORT_NAME() to DRIVER_REGISTER_* macro.

[dpdk-dev] [PATCH v10 17/25] eal: remove PDEV/VDEV unused code

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

- Remove checks for VDEV from rte_eal_vdev_(init/uninint) as all devices
  are inherently virtual here.
- PDEVs perform PCI specific inits - rte_eal_dev_init() need not call
  rte_driver->init();

[dpdk-dev] [PATCH v10 18/25] drivers: convert VDRV to use RTE VDEV Driver

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

All PMD_VDEV drivers can now use rte_vdev_driver instead of the
rte_driver (which is embedded in the rte_vdev_driver).

[dpdk-dev] [PATCH v10 19/25] eal: remove unused PMD types

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

- All devices register themselfs by calling a kind of DRIVER_REGISTER_XXX.
  The PMD_REGISTER_DRIVER is not used anymore.
- PMD_VDEV type is also not being used - can be removed from all VDEVs.

Note: PMD_REGISTER_DRIVER usage by PMDINFO tool and its documentation has
      not yet been removed.

[dpdk-dev] [PATCH v10 22/25] eal/pci: inherit RTE driver in PCI driver

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Remove the 'name' member from rte_pci_driver and move to generic
rte_driver.

Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has
been populated into the rte_driver.name member - assignments through
eth_driver has been removed.

[dpdk-dev] [PATCH v10 25/25] eal/pci: create RTE device list and fallback on its members

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Now that rte_device is available, drivers can start using its members
(numa, name) as well as link themselves into another rte_device list.

As of now no one is using this list, but can be used for moving over all
devices (pdev/vdev/Xdev) and perform bulk actions (like cleanup).

OK.
Should I still wait for more patch level comments before releasing v11?

Ok. I will do this.

I introduced this based on the merging of Jan's series and subsequent use in SoC framework series. But, yes, it is not being used in this series.
I will remove it.

Yes, I updated the patch based on your suggestion but didn't notice that I had put a counter notice about this in commit log in v9. I will remove this.

Well, this patch didn't update the documentation and I was not sure if the only change for PMD Info tool is in the mk file as per your patch. 
I will change the suggested patch and add documentation related note in the commit log.

Are you suggesting in the code as a comment? If so, I don't think that is good idea.

> But I would do this in "drivers: convert all phy drivers as PCI drivers".

If I have to update, I will use the above patch.

That is because I didn't like using 'probe/remove' for VDEV. The semantic of probing is not really correct for a virtual device. We 'add' and initialize the virtual device actually.
If you and other still feel that making it analogous with PCI probe/remove, I will update it.

[dpdk-dev] [PATCH v11 00/24] Introducing rte_driver/rte_device generalization

[Shreyansh Jain]

Based on master (e15922d75)

Background:
===========

It includes two different patch-sets floated on ML earlier:
 * Original patch series is from David Marchand [1], [2].
  `- This focused mainly on PCI (PDEV) part
  `- v7 of this was posted by me [8] in August/2016
 * Patch series [4] from Jan Viktorin
  `- This focused on VDEV and rte_device integration

Introduction:
=============

This patch series introduces a generic device model, moving away from PCI 
centric code layout. Key change is to introduce rte_driver/rte_device 
structures at the top level which are inherited by 
rte_XXX_driver/rte_XXX_device - where XXX belongs to {pci, vdev, soc (in 
future),...}.

Key motivation for this series is to move away from PCI centric design of 
EAL to a more hierarchical device model - pivoted around a generic driver 
and device. Each specific driver and device can inherit the common 
properties of the generic set and build upon it through driver/device 
specific functions.

Earlier, the EAL device initialization model was:
(Refer: [3])

--
 Constructor:
  |- PMD_DRIVER_REGISTER(rte_driver)
     `-  insert into dev_driver_list, rte_driver object

 rte_eal_init():
  |- rte_eal_pci_init()
  |  `- scan and fill pci_device_list from sysfs
  |
  |- rte_eal_dev_init()
  |  `- For each rte_driver in dev_driver_list
  |     `- call the rte_driver->init() function
  |        |- PMDs designed to call rte_eth_driver_register(eth_driver)
  |        |- eth_driver have rte_pci_driver embedded in them
  |        `- rte_eth_driver_register installs the 
  |           rte_pci_driver->devinit/devuninit callbacks.
  |
  |- rte_eal_pci_probe()
  |  |- For each device detected, dev_driver_list is parsed and matching is
  |  |  done.
  |  |- For each matching device, the rte_pci_driver->devinit() is called.
  |  |- Default map is to rte_eth_dev_init() which in turn creates a
  |  |  new ethernet device (eth_dev)
  |  |  `- eth_drv->eth_dev_init() is called which is implemented by 
  `--|    individual PMD drivers.

--

The structure of driver looks something like:

 +------------+     ._____.
 | rte_driver <-----| PMD |___
 |  .init     |     `-----`   \
 +----.-------+      |         \
      `-.            |         What PMD actually is
         \           |          |
          +----------v----+     |
          | eth_driver    |     |
          | .eth_dev_init |     |
          +----.----------+     |
               `-.              |
                  \             |
                   +------------v---+
                   | rte_pci_driver |
                   | .pci_devinit   |
                   +----------------+

  and all devices are part of a following linked lists:
    - dev_driver_list for all rte_drivers
    - pci_device_list for all devices, whether PCI or VDEV


>From the above:
 * a PMD initializes a rte_driver, eth_driver even though actually it is a 
   pci_driver
 * initialization routines are passed from rte_driver->pci_driver->eth_driver
   even though they should ideally be rte_eal_init()->rte_pci_driver()
 * For a single driver/device type model, this is not necessarily a
   functional issue - but more of a design language.
 * But, when number of driver/device type increase, this would create
   problem in how driver<=>device links are represented.

Proposed Architecture:
======================

A nice representation has already been created by David in [3]. Copying that

 * Each driver type has its own structure which derives from the generic 
   rte_driver structure.
   \- Each driver type maintains its own list, at the same time, rte_driver
      list also exists - so that *all* drivers can be looped on, if required.
 * Each device, associated with one or more drivers, has its own type
   derived from rte_device
   \- Each device _may_ maintain its own list (for example, in current 
      implementation, vdev is not maintaining it).

==Introducing a new device/driver type implies==
  - creating their own rte_<xxx>.h file which contains the device/driver
    definitions.
  - defining the DRIVER_REGISTER_XXX helpers

==Hotplugging Support==
  - devices should be able to support attach/detach operations.
  - Earlier these functions were part of ethdev. They have been moved to eal
    to be more generic.

 This patch is part of larger aim to:

 --------------------+ <is type of>
 eth_driver (PMD)    |-------------> rte_driver
 crypto_driver (PMD) |               ^
 <more in future>    |               |
 --------------------+               | <inherits>
                                    /
           +-----------------------/+
           | rte_pci_driver         |
           | rte_vdev_driver        |
           | rte_soc_driver         |
           | rte_xxx_driver         |

 Where PMD devices (rte_eth_dev, rte_cryptodev_dev) are connected to their
 drivers rather than explicitly inheriting type specific driver (PCI, etc).


About the Patches:
==================

There are a large number of patches for this - primarily because the changes 
are quite varied and keeping them logically separate yet compilable is
important. Most of the patches are small and those which are large touch the
drivers (PMDs) to accommodate the structure changes:

 - Patches 0001~0002 are for introducing the container_of function (so that 
   rte_device can be obtained from rte_pci_device, for example), and 
   removing unused code.
 - Patch 0003 converts the PCI devinit/devuninit method names to probe/
   remove and correspondingly updates all drivers where impact it. VDEV
   based init/uninit have not been modified.
 - Patches 0004~0007 just perform the ground work for enabling change from
   rte_driver/eth_driver based PMDs to rte_xxx_driver based PMDs
 - In patch 0008, all the pdev PMDs are changed to support rte_pci_driver (
   including cryptodev, which is eventually generalized with PCI)
 - Patch 0009~0011 merge the crypto and pci functions for registration and 
   naming.
 - Patches 0011~0013 deal with hotplugging - hotplug no more invokes scan of 
   complete bus and has been generalized into EAl from ethdev.
 - Patches 0014 introduces vdev init/uninit into separate C units and 
   enables its compilation. Patch 0016~0017 build on it and remove the 
   remaining legacy support for vdev/pdev distinctions.
 - Patches 0017~0021 enable the vdev drivers to register using the 
   DRIVER_REGISTER_* operations, and remove their rte_driver->init()
 - Patch 0022 enables the rte_driver registration into a common driver
   linked list.
 - Patche 0024 introduce the rte_device, a generalization of 
   rte_xxx_device, and associated operation of creating rte_device linked 
   list. It also enables the drivers to use rte_device.name/numa_node 
   members rather than rte_xxx_device specific members.

Future Work/Pending:
===================
 - Presently eth_driver, rte_eth_dev are not aligned to the rte_driver/
   rte_device model. eth_driver still is a PCI specific entity. This
   has been highlighted by comments from Ferruh in [9].
 - Some variables, like drv_name (as highlighted by Ferruh), are getting
   duplicated across rte_xxx_driver/device and rte_driver/device.

- Removed patch for container_of posted in v10 (01/25)
- Fix review comments from David: [10]

Changes since v9:
- Rebased over master (58efd680d5e)
- Fix issues reported by checkpatch and check-git-log, including changing
  headline of the patches to adhere to these scripts.
- Corrected the patch author field
- Renamed devinit/devuninit for pci_driver to probe/remove as per
  suggestion from David
- Fix for PMD Info gen tool using patch from David
- Fixed review comments [R1], some part of [R2], [R3] using patch from
  David, [R4], [R5] and some inputs from [R6].

Changes since v8:
- Some review comments from Ferruh Yigit & Reshma Pattan have been fixed.
 = Though changes in mlx4/mlx5/szedata2 have been done, I am still unable
   to verify those in absence of a proper environment at my end.
 = Comment from Ferruh for eth_driver, drv_name are not fixed yet.
- Added a 'Future work' section in Covering letter

Changes since v7:
- Rebase over master (e22856313fff2)
- Merge the patch series by David [1][2] and Jan [4] into a single set
  hereafter, PCI and VDEV, both are re-factored for rte_device/driver
  model

Changes since v6:
- rebase over 16.07 (b0a1419)
- DRIVER_REGISTER_PCI macro is now passed pci_drv rather than drv
- review comments regarding missing information in log messages
- new API additions to 16.11 map objects
- review comment in [5] and [7] are not included in this series.

Changes since v5:
- Rebase over master (11c5e45d8)
- Rename RTE_EAL_PCI_REGISTER helper macro to DRIVER_REGISTER_PCI to be
  in sync with DRIVER_REGISTER_PCI_TABLE. [Probably, in future, both can
  be merged]
- Modifications to bnxt and thunderx driver PMD registration files for
  using the simplified PCI device registration helper macro

Changes since v4:
- Fix compilation issue after rebase on HEAD (913154e) in previous series
- Retain rte_eth_dev_get_port_by_name and rte_eth_dev_get_name_by_port
  which were removed by previous patchset. These are being used by pdump
  library

Changes since v3:
- rebase over HEAD (913154e)
- Update arguments to RTE_EAL_PCI_REGISTER macro as per Jan's suggestion
- modify qede driver to use RTE_EAL_PCI_REGISTER
- Argument check in hotplug functions

Changes since v2:
- rebase over HEAD (d76c193)
- Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue

Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
  dropped for now, we can do this once vdev drivers have been converted

[dpdk-dev] [PATCH v11 01/24] eal: remove duplicate function declaration

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

rte_eal_dev_init is declared in both eal_private.h and rte_dev.h since its
introduction.
This function has been exported in ABI, so remove it from eal_private.h

Fixes: e57f20e05177 ("eal: make vdev init path generic for both virtual and pci devices")

[dpdk-dev] [PATCH v11 02/24] pci: no need for dynamic tailq init

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).

A nice side effect is that pci drivers can now register in constructors.

[dpdk-dev] [PATCH v11 03/24] eal/pci: replace PCI devinit/devuninit with probe/remove

[Shreyansh Jain]

Probe and Remove are more appropriate names for PCI init and uninint
operations. This is a cosmetic change.

Only MLX* uses the PCI direct registeration, bypassing PMD_* macro. The
calls backs for this too have been updated.

VDEV are left out. For them, init/uninit are more appropriate.

[dpdk-dev] [PATCH v11 06/24] eal: introduce PCI device init macros

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Introduce a RTE_INIT macro used to mark an init function as a constructor.
Current eal macros have been converted to use this (no functional impact).
DRIVER_REGISTER_PCI is added as a helper for pci drivers.

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

crypto and ethdev drivers aligned to PCI probe/remove. These wrappers are
mapped directly to PCI resources.
Existing handlers for init/uninit can be easily reused for this.

These functions are used by the drivers only (as helpers).
So they should be marked @internal (added after applying the patch).

[dpdk-dev] [PATCH v11 08/24] drivers: convert all phy drivers as PCI drivers

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.

Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
  steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

Update documentation for replacing an example referring to
PMD_REGISTER_DRIVER.

[dpdk-dev] [PATCH v11 09/24] drivers: remove driver register callbacks for crypto/net

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Now that all pdev are pci drivers, we don't need to register crypto and
ethdev drivers through a dedicated channel.

[dpdk-dev] [PATCH v11 10/24] eal/pci: helpers for device name parsing/update

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

- Move rte_eth_dev_create_unique_device_name() from ether/rte_ethdev.c to
  common/include/rte_pci.h as rte_eal_pci_device_name(). Being a common
  method, can be used across crypto/net PCI PMDs.
- Remove crypto specific routine and fallback to common name function.
- Introduce a eal private Update function for PCI device naming.

[dpdk-dev] [PATCH v11 12/24] eal: add hotplug operations for PCI and VDEV

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Hotplug invocations, which deals with devices, should come from the layer
that already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

[dpdk-dev] [PATCH v11 13/24] ethdev: convert to EAL hotplug

[Shreyansh Jain]

From: David Marchand <david.marchand@6wind.com>

Remove bus logic from ethdev hotplug by using eal for this.

Current api is preserved:
- the last port that has been created is tracked to return it to the
  application when attaching,
- the internal device name is reused when detaching.

We can not get rid of ethdev hotplug yet since we still need some
mechanism to inform applications of port creation/removal to substitute
for ethdev hotplug api.

dev_type field in struct rte_eth_dev and rte_eth_dev_allocate are kept as
is, but this information is not needed anymore and is removed in the
following commit.

[dpdk-dev] [PATCH v11 15/24] eal: extract vdev infra

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Move all PMD_VDEV-specific code into a separate module and header
file to not polute the generic code anymore. There is now a list
of virtual devices available.

The rte_vdev_driver integrates the original rte_driver inside
(C inheritance). The rte_driver will be however change in the
future to serve as a common base for all other types of drivers.

The existing PMDs (PMD_VDEV) are to be modified later (there is
no change for them at the moment).

[dpdk-dev] [PATCH v11 16/24] eal: remove PDEV/VDEV unused code

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

- Remove checks for VDEV from rte_eal_vdev_(init/uninint) as all devices
  are inherently virtual here.
- PDEVs perform PCI specific inits - rte_eal_dev_init() need not call
  rte_driver->init();

[dpdk-dev] [PATCH v11 17/24] drivers: convert VDRV to use RTE VDEV Driver

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

All PMD_VDEV drivers can now use rte_vdev_driver instead of the
rte_driver (which is embedded in the rte_vdev_driver).

[dpdk-dev] [PATCH v11 18/24] eal: remove unused PMD types

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

- All devices register themselfs by calling a kind of DRIVER_REGISTER_XXX.
  The PMD_REGISTER_DRIVER is not used anymore.
- PMD_VDEV type is also not being used - can be removed from all VDEVs.

[dpdk-dev] [PATCH v11 21/24] eal/pci: inherit RTE driver in PCI driver

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Remove the 'name' member from rte_pci_driver and move to generic
rte_driver.

Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has
been populated into the rte_driver.name member - assignments through
eth_driver has been removed.

[dpdk-dev] [PATCH v11 24/24] eal/pci: create RTE device list and fallback on its members

[Shreyansh Jain]

From: Jan Viktorin <viktorin@rehivetech.com>

Now that rte_device is available, drivers can start using its members
(numa, name) as well as link themselves into another rte_device list.

As of now no one is using this list, but can be used for moving over all
devices (pdev/vdev/Xdev) and perform bulk actions (like cleanup).

Re: [dpdk-dev] [PATCH v11 00/24] Introducing rte_driver/rte_device generalization

[Matej Vido]

Hi Shreyansh,

I have tested this patch-set with szedata2 driver and it works fine.

Regards,

Matej

What about those pending work?

I would add more remaining issues:
- probe/remove naming could be applied to vdev for consistency
- rte_eal_device_insert must be called in vdev
- REGISTER macros should be prefixed with RTE_
- Some functions in EAL does not need eal_ in their prefix:
	rte_eal_pci_   -> rte_pci_
	rte_eal_dev_   -> rte_dev_
	rte_eal_vdev_  -> rte_vdev_
	rte_eal_driver -> rte_drv_
	rte_eal_vdrv   -> rte_vdrv_

Both the above are already part of my todo list.

Is that for uniformity reasons? I still feel 'probe/remove' are not 
appropriate for a virtual device. init/deinit are more appropriate. As 
for PCI, probe/remove are standard parlance and hence suit it better 
than init/deinit.

Nevertheless, uniform naming convention can have its benefits - ease of 
code understanding being one.

Change is simple once we come to a conclusion.

Ok.

> - REGISTER macros should be prefixed with RTE_

That would include:
  DRIVER_REGISTER_VDEV
  DRIVER_REGISTER_PCI_TABLE
  DRIVER_REGISTER_PCI

I will publish a patch soon. This would be fairly straightforward change.

It can be merged with changes for:
  - drv_name
  - EAL_ before _REGISTER_ macros
  - eth_driver => rte_driver naming

PCI probe is "scan + checks + init".
The vdev requires "args parsing + checks + init".
The device will not be initialized if checks fail,
e.g. missing support or name conflict.
I think it could fit in "probe" rather than "init".

The remove word looks appropriate in both cases.

Yes that's the other pro for "probe/remove".

I caught while running ABI validation script today, I think this patch
should increase LIBABIVER of:
- lib/librte_cryptodev
- lib/librte_eal
- lib/librte_ether

Yes, this is the document.

Briefly, if library becomes incompatible with existing applications,
LIBABIVER needs to be increased to indicate this.

Increasing LIBABIVER changes dynamic library name and so_name, and this
cause existing application do not work with this new library. Not
increasing the LIBABIVER, app may start running but can have segfault or

Thanks for explanation. I understand.
I will send across another patch for this.

It should, and it in fact should wait a release if it hadn't been documented as
a comming change.

It was announced in release 16.04:

While bumping LIBABIVER, the deprecation notices must be removed,
and the API/ABI changes noted in the release notes, please.

[dpdk-dev] [PATCH 0/9] pci cleanup and blacklist rework

[David Marchand]

Before 2.2.0 release, while preparing for more changes in eal (and fixing
a problem reported by Roger M. [1]), I came up with this patchset that
tries to make the pci code more compact and easier to read.

I did limited testing, but this has been in my tree for quite some time
now, so sending this to get feedback for 2.3 / 16.04.


The 4th patch introduces a change in linux eal.
Before, if a pci device was bound to no kernel driver, eal would set kdrv
to "unknown". With this change, kdrv is set to "none".
This might make it possible to avoid the old issue of virtio devices being
used by dpdk while still bound to kernel driver reported by Franck B. [2].
I'll let virtio guys look at this.
At the very least, it makes more sense to me.


The 5th and 6th patches could be squashed.
I just find it easier to review this way.


In the 8th patch, I noticed that a driver lookup is done when detaching a
pci device while this makes no sense and looks buggy to me.


The last patch moves pci blacklist evaluation to rte_eal_pci_probe().
With this, it is now possible to attach a pci device blacklisted
initially.
I am not entirely happy with this last patch, I will try to send a
different solution next week (hooks in pci layer).

[dpdk-dev] [PATCH 1/9] pci: no need for dynamic tailq init

[David Marchand]

These lists can be initialized once and for all at build time.
With this, those lists are only manipulated in a common place
(and we could even make them private).
