[dpdk-dev] [PATCH 0/2] User-space Ethtool

[dpdk-dev] [PATCH 0/2] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.
ethtool: adding new ethtool api support

v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (2):
  ethdev: add api to set default mac address
  ethtool: add new library to provide ethtool-alike APIs

[dpdk-dev] [PATCH 2/2] ethtool: add new library to provide ethtool-alike APIs

[Liang-Min Larry Wang]

adding a new library based upon ethdev APIs to provide API's that bear
the same functionality as ethtool_ops (linux/ethtool.h) and net_device_ops
(linux/netdevice.h).

The API's for ethtool like things are valuable, but please contain
it more.

I think you should contain this to only those things which are in
the original Linux ethtool. Adding yet another layer that calls DPDK
for open/close/start stop just adds more layers with out providing any
value.

The ones I would keep:
	get_driverinfo
	get_link

The ones I would add:
	cmd - for speed/duplex negotiation
	eeprom - for eeprom access
	eee - for energy awareness
	coalesce - for packet coalescing
	ringparam - to allow changing ring parameters
              (existing rx config model is limiting)
	pauseparam - existing flow control in DPDK is mess
	gstrings/stats - map to XSTATS
	test - for  offline tests
	dump - for register dump
	features - control offload features
	perm_addr - base mac address

The design decision is to keep ethdev as THE interface for all the external API, so ethtool APIs are designed based upon ethdev API. At the meantime, the ethtool APIs are designed to enable users to migrate designs based upon kernel-space ethtool. The open/close/start are put in place to enable quick migration.

As for the suggestion, eeprom/ringparam/pauseparam/register-dump are on their way for latter release. For other ops, I will take the feedback for future planning.

But there is no open/close/start in ethtool in kernel.
Anyway ethtool is currently on the disfavored list from kernel developers.
What about netlink or something better?

Remember each new API creates more long term compatiablity and ABI issues.
So I am against introducing any new API that does the same thing as existing API's.

Just to clarify APIs supported by this ethtool api: there are net_open and net_stop and no net_start. Both functions are put in place to support net_device_ops::ndo_open and net_device_ops::ndo_close as defined in linux/netdevice.h

I get the feeling there is some use case you are not telling the list about.
What kind of application would use this api only. Why or how would DPDK application
be involved in net_device_ops. If you are planning on putting DPDK in the kernel
there are lots of other issues including kernel ABI stability and licensing
that need to be dealt with.

(I'm manually adding ">" through my email, outlook, to make my reply. I apology if I make any mistake on adding ">" in wrong place)
No, we don't plan to put DPDK into kernel space, and this patch has nothing to do with bifurcated driver that was announced for DPDK 2.0 then got scrubbed (or deferred). In contrary, the entire ethtool API (more support is coming) is designed to assist applications that were designed based upon kernel ethtool to migrate into user-space driver based DPDK libraries. Being said that, as you are aware the kernel version of ndo_open/ndo_close is more than just start and stop device. The initial implementation is to provide minimum functionality (strip off all the kernel related state management). In the future release (we need comments like yours), we will continue make improvement. So this new API can be another alternative for applications to run device management.

Just to clarify my last reply: when I said "... based upon kernel ethtool to migrate ...", I was referring to both ethtool and net_device_op.

[dpdk-dev] [PATCH v4 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:s
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool

[dpdk-dev] [PATCH v4 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_leng
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_leng
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom
- rte_eth_dev_get_ringparam
- rte_eth_dev_set_ringparam

to enable reading device parameters (mac-addr, register,
eeprom, ring) based upon ethtool alike
data parameter specification.

<dharton> I know this is a bit of a nit but please consider changing "leng" to "length".
Some places already use "length" in the diffs below so using length would be consistent.

Wonder what that structure is for?
I can't see it used in any function below?

Seems that *get_reg* stuff, will be really good addition for DPDK debugging abilities.
Though, I'd suggest we change it a bit to make more generic and flexible:

Introduce rte_eth_reg_read/rte_eth_reg_write(),
or probably even better rte_pcidev_reg_read /rte_pcidev_reg_write at EAL.
Something similar to what port_pci_reg_read/port_pci_reg_write() are doing now at testpmd.h.

struct rte_pcidev_reg_info {
   const char *name;
   uint32_t endianes, bar, offset, size, count;
};

int rte_pcidev_reg_read(const struct rte_pci_device *, const struct rte_pcidev_reg_info *, uint64_t *reg_val);

Then:
int rte_eth_dev_get_reg_info(port_id, const struct rte_pcidev_reg_info **info);

So each device would store in info a pointer to an array of it's register descriptions
(finished by zero elem?).

Then your ethtool (or any other upper layer) can do the following to read all device regs:

const struct rte_eth_dev_reg_info *reg_info;
struct rte_eth_dev_info dev_info;

rte_eth_dev_info_get(pid, &dev_info);
rte_eth_dev_get_reg_info(port_id, &reg_info);

for (i = 0; reg_info[i].name != NULL; i++) {
   ...
   rte_pcidev_read_reg(dev_info. pci_dev, reg_info[i], &v);
  ..
}

I think it will be a useful addition to the ethdev API  to have an ability to retrieve current RX/TX queue parameters.
Though again, it need to be more generic, so it could be useful for non-ethtool upper layer too.
So I suggest to modify it a bit.
Something like that:

struct rte_eth_tx_queue_info {
    struct rte_eth_txconf txconf;
    uint32_t nb_tx_desc;
    uint32_t nb_max_tx_desc; /*max allowable TXDs for that queue */
    uint32_t nb_tx_free;            /* number of free TXDs at the moment of call. */
    /* other tx queue data. */ 	
};

int rte_etdev_get_tx_queue_info(portid, queue_id, struct rte_eth_tx_queue_info *qinfo)

Then, your upper layer ethtool wrapper, can implement yours ethtool_get_ringparam() by:

 ...
 struct rte_eth_tx_queue_info qinfo;
 rte_ethdev_get_tx_queue_info(port, 0, &qinfo);
ring_param->tx_pending = qinfo.nb_tx_desc -  rte_eth_rx_queue_count(port, 0);

Or probably even:
ring_param->tx_pending = qinfo.nb_tx_desc - qinfo.nb_tx_free;

Same for RX.

I am a bit confused, what particular value of rte_dev_ring_info will be allowed to change?
You can't change number of RXD/TXD at runtime.
You have to stop the device first, and then reconfigure particular queue(s).
Again, you can't reset RXF/TXD without stopping RX/TX first.
So what that function is supposed to do?
As I can see currently, none of the PMD in your patch support it.

Good catch, this is designed for other ethtool ops that I did not include in this release, I will remove this from next fix.

The proposed reg info structure allows future improvement to support individual register read/write.
Also, because each NIC device has a very distinguish register definition.
So, the plan is to have more comprehensive interface to support query operation (for example, register name) before introduce individual/group register access.
Points taken, the support will be in future release.

For now, this descriptor ring information is used by the ethtool op. 
To make this interface simple, i.e. caller doesn't need to access other queue information.
The plan it so keep this information as it is. 
For the expansion, the ethdev can invoke the same dev op to add this information.

Exactly, setting RXD/TXD will require some change on kernel (RX/TX burst) function.
As you already observe that there is no dev_op registered for set_ring.
The API is created as a placeholder for future implementation.
There are a couple of idea thrown around (such as mono- increase/decrease to avoid buffer overrun).
Any suggestion is welcome.

Sorry, didn't get you.
So you are ok to make these changes in next patch version?

I just repeat what I said to you in off-line conversation:
ethdev API is not equal ethtool API.
It is ok to add  a new function/structure to ethdev if it really needed, but we should do mechanical one to one copy.
It is much better to add  a function/structure that would be more generic, and suit other users, not only ethtool.
There is no point to have dozen functions in rte_ethdev API providing similar information.
BTW, I don't see how API I proposed is much more  complex, then yours one.

I would like to get a consensus from dpdk community on how to provide register information.
Currently, it's designed for debug dumping. The register information is very hardware dependent.
Need to consider current supported NIC device and future devices for DPDK, so we won't make it a bulky interface.

Well, that' ok, but if it is just a trial patch that is not intended to be applied, then you should mark it as RFC.

> Currently, it's designed for debug dumping. The register information is very hardware dependent.

Ok, could you explain what exactly  concerns you in the approach described above?
What part you feel is bulky?

I don't see how they are different.
Looking at ixgbe_get_ringparam(), it returns:
rx_max_pending - that's a static IXGBE PMD value (max possible number of RXDs per one queue).
rx_pending - number of RXD currently in use by the HW for queue 0 (that information can be changed at each call).

With the approach I suggesting - you can get same information for each RX queue by
calling rte_ethdev_get_rx_queue_info() and rte_eth_rx_queue_count(). 
Plus you are getting other RX queue data.

Another thing - what is practical usage of the information you retrieving now by get_ringparam()?
Let say it returned to you: rx_max_pending=4096; rx_pending=128;
How that information would help to understand what is going on with the device?
Without knowing  value of nb_tx_desc for the queue, you can't say is you queue full or not.
Again, it could be that all your traffic going through some other queue (not 0).
So from my point rte_eth_dev_get_ringparam()  usage is very limited, and doesn't
provide enough information about current queue state.

Same thing applies for TX. 

> It's the desire of this patch to separate each data structure to avoid cross dependency.

That's too cryptic to me.
Could you explain what cross dependency you are talking about?

After careful review the suggestion in this comment, and review the existing dpdk source code. 
I came to realize that neither rte_ethdev_get_rx_queue_info, rte_ethdev_get_tx_queue_info, struct rte_eth_rx_queue_info and struct rte_eth_tx_queue_info are available in the existing dpdk source code. I could not make a patch based upon a set of non-existent API and data structure.

Right now, in dpdk.org source code, struct  rte_eth_dev_ring_info, struct  rte_dev_eeprom_info and struct  rte_dev_reg_info
don't exist also.
Same as  all these functions:

rte_eth_dev_default_mac_addr_set
rte_eth_dev_reg_length
rte_eth_dev_reg_info
rte_eth_dev_eeprom_length
rte_eth_dev_get_eeprom
rte_eth_dev_set_eeprom
rte_eth_dev_get_ringparam

All this is a new API that's you are trying to add.
But, by some reason you consider it is ok to add 'struct  rte_eth_dev_ring_info', but couldn't add  struct 'rte_ethdev_get_tx_queue_info'
That just doesn't make any sense to me.
In fact, I think our conversation is going in cycles.
If you are not happy with the suggested approach, please provide some meaningful reason why.

All the API's and data structure that you have questions in this comment are available from the submitted patch, you could run to see if it works.
What I learned from your comments are a couple of API name and incomplete data structure description, so I could not make my patch according to your suggestion.
If you strongly feel the API's that you are proposing are useful for get_ringparam(), please create a patch and submit it for evaluation.
As coded in this patch, it's a simple and clean interface and most important, it can be validated and it works.

Here is the patch I submitted for proposed changes at re_ethdev and PMDs, as discussed:
http://dpdk.org/dev/patchwork/patch/5482/
Please have a look.

With that, get_ringraram for ethtool shim layer, would look something like:

int
rte_ethtool_get_ringparam(uint8_t port_id,
	struct ethtool_ringparam *ring_param)
{
	struct rte_eth_rx_qinfo rx_qinfo;
                struct rte_eth_tx_qinfo tx_qinfo;
	int status;

                if ((status = rte_eth_rx_queue_info_get (port_id, 0, &rx_qinfo)) != 0)
		return status;

               if ((status = rte_eth_tx_queue_info_get (port_id, 0, &tx_qinfo)) != 0)
		return status;

              memset(ring_param, 0, sizeof(*ring_param)

              ring_param->rx_pending = rx_qinfo.nb_desc;
              ring_param->tx_pending = tx_qinfo.nb_desc;
              ring_param->rx_max_pending = rx_qinfo.max_desc;
              ring_param->tx_max_pending = tx_qinfo.max_desc;

              return 0;
}


As you can see, the changes at ethtool are minimal, while it provides desired info.
>From other side, we have much more generic and easily extendable API at rte_ethdev.

It seems the new API aims at providing users a mechanism to quickly and 
gracefully migrate from using ethtool/ioctl calls.  The provided get/set 
ring param info is very similar to that of ethtool and facilitates the
ethtool needs.

While additional enhancements to the API to provide additional details 
such as those you have suggested are certainly possible, I believe Larry 
is stating those ideas are outside the scope he has intended with the 
API introduction and that they should be discussed further and delivered
in a future patch.

Does that seem reasonable?

Dave

I am fine with that goal in general.
But it doesn't mean that all ethool API should be pushed into rte_ethdev layer.
That's why  a shim layer on top of rte_ethdev is created -
it's goal is to provide for the upper layer an ethool-like API and
hide actual implementation based on rte_ethdev API inside.

If rte_ethtool shim layer has to provide get/set ring_param API as it is - that's ok with me.
Though I don't see any good reason why rte_ethdev layer API should restrict itself with exactly the same ethtool-like API.
As I said before - current practical usage of rte_eth_dev_get_ringparam() looks quite limited.
Probably it just me, but I don't see how user can conclude what is the device state,
using  information provided by rte_eth_dev_get_ringparam().

My concern is - if we'll introduce rte_eth_dev_get_ringparam() as it suggested by Larry now,
one of two things would happen:
- no one except ethtool shim layer would use it.
- people will complain that it doesn't provide desired information. 
So, in next release we'll have to either introduce a new function and support 2 functions doing similar things
(code duplication), or modify existing API (ABI breakage pain).

It would be much better to introduce a new rte_ethdev API here that would be generic enough
and fit common needs, not only one particular case (ethtool).
After all, I don't think the changes I suggesting  differ that much from current approach.

Actually a quick questions to you guys:
Looking at linux struct ethtool_ringparam description, I am seeing:
http://lxr.free-electrons.com/source/include/uapi/linux/ethtool.h:
@rx_pending: Current maximum number of pending entries per RX ring

And all linux driver I looked at (ixgbe,i40e,virtio,vmxbet3) returns number
of configured RX descriptors for queue 0.
In DPDK terms: nb_desc for the queue.

While in Larry's patch,  ixgbe_get_ringparam() for rx_pending returns
number of RX descriptors that are in HW use (for queue 0).
So, did you intentionally change linux ethool get_ringparam() behaviour here,
or is it just a mistake?

If you don't plan to implement it in current patch-set, then it is better to remove it for now.
About suggestions - as I said, I don't think it is doable without stopping (and reconfiguring) the queue.
Again not sure, why do you want to do that run-tme.

That's a very valid point. To support run-time ring descriptor size adjustment, we need to stop traffic in some way.

[dpdk-dev] [PATCH v4 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v5 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v5 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom
- rte_eth_dev_get_ringparam

to enable reading device parameters (mac-addr, register,
eeprom, ring) based upon ethtool alike
data parameter specification.

[dpdk-dev] [PATCH v5 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v6 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v6 change:
- Rebase to match new changes over dpdk repository (librte_ether)
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool

[dpdk-dev] [PATCH v6 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom
- rte_eth_dev_get_ringparam

to enable reading device parameters (mac-addr, register,
eeprom, ring) based upon ethtool alike
data parameter specification.

[dpdk-dev] [PATCH v6 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

[dpdk-dev] [PATCH v7 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool

[dpdk-dev] [PATCH v7 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

Would it be possible to directly set mac_addr[0] if device does not
provide a device driver specific override?

I would yield this question to Konstantin since this information is used by get mac addr API.

Some minor nits:
  * for consistency you should add valid port check here.
  * style:
    - don't do assignment in if() unless it really helps readability
    - need whitespace

	if (!rte_eth_dev_is_valid_port(portid)) {
		PMD_DEBUG_TRACE("Invalid port_id=%d\n", port_id);
		return -ENODEV;
	}

	dev = &rte_eth_devices[port_id];
	if (dev == NULL) {
		PMD_DEBUG("Invalid port device\n");
		return -ENODEV:
	}
...

This code pattern is so common it really should be a function.

	dev = rte_eth_dev_get(port_id);
	if (dev == NULL) {
		PMD_DEBUG("Invalid port device\n");
		return -ENODEV;
	}

And then add a macro to generate this??

This is used through-out the rte_ethdev.c, should it be done to the entire file?

[dpdk-dev] [PATCH v7 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

I agree with having a more complete API, but have some nits to pick.
Could the API be more abstract to reduce ABI issues in future?

I know choosing names is hard, but as a Linux developer ethtool has a very
specific meaning to me.
This API encompasses things broader than Linux ethtool and has different
semantics therefore
not sure having something in DPDK with same name is really a good idea.

It would be better to call it something else like netdev_?? Or dpnet_??

Which API? Are you referring to the APIs over ethdev level, or something else?
More abstract on input/output data structure definition or else? Could you be more specific?

Just to clarify the naming suggestion, in this patch, the prefix “ethtool” only appears on example and on this patch description.
Are you suggesting changing the name over example/l2fwd-ethtool or on this patch description, or may be both?

[dpdk-dev] [PATCH v8 0/5] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Andrew G. Harvey (1):
  Changed register tables to const.

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool

[dpdk-dev] [PATCH v8 1/5] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

I agree in principal, but has lots of style issues (see report from checkpatch).

This part of code is the same as coding in other part of the same file such as:

int
rte_eth_dev_bypass_wd_timeout_show(uint8_t port_id, uint32_t *wd_timeout)
{
	struct rte_eth_dev *dev;

	if (!rte_eth_dev_is_valid_port(port_id)) {
		PMD_DEBUG_TRACE("Invalid port_id=%d\n", port_id);
		return -ENODEV;
	}

	if ((dev= &rte_eth_devices[port_id]) == NULL) {
		PMD_DEBUG_TRACE("Invalid port device\n");
		return -ENODEV;
	}

	FUNC_PTR_OR_ERR_RET(*dev->dev_ops->bypass_wd_timeout_show, -ENOTSUP);
	(*dev->dev_ops->bypass_wd_timeout_show)(dev, wd_timeout);
	return 0;
}
I would suggest that someone (either you or me) to do a code cleaning after all patches for DPDK 2.1 have been decided. Does that sound good to you?

[dpdk-dev] [PATCH v8 4/5] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v9 0/5] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (5):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool
  ixgbe/igb: changed register tables to const

[dpdk-dev] [PATCH v9 1/5] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

The dev arg is used, and therefore should not be marked __rte_unused.

I don't care what checkpatch says, this an example of a loop
which reads better as:

        while ((reg_group = reg_set[g_ind++]))
               count += ixgbe_regs_group_count(reg_group);

All pre-set reg_info should be const.

And this as well:

[dpdk-dev] [PATCH v9 4/5] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Since code is not yet accepted, all these changes should be rolled back into
next (v10) of the original patch.

Are you saying that we could not have a 5/5 needs to be applied to 2/5 and 3/5

All the const changes are moved to the same patches on igb or ixgbe.

On v10, I had made changes according to your feedback. I did more changes on v11/v12/v13 based upon incremental changes on master repository. Are there any pending issue on this patch?

Thanks,

[dpdk-dev] [PATCH v10 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v10 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

[dpdk-dev] [PATCH v10 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v11 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v11 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_reg_length
- rte_eth_dev_reg_info
- rte_eth_dev_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

[dpdk-dev] [PATCH v11 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v12 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v12 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add two new apis: rte_eth_dev_default_mac_addr_set
and rte_eth_ethtool_dev_info to enable
reading device parameters (mac, register, eeprom,
pause, ring) based upon ethtool alike
data parameter sepcification.

[dpdk-dev] [PATCH v12 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[Liang-Min Larry Wang]

v13 changes:
- Rebase beause patch 1588
v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

[dpdk-dev] [PATCH v13 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add two new apis: rte_eth_dev_default_mac_addr_set
and rte_eth_ethtool_dev_info to enable
reading device parameters (mac, register, eeprom,
pause, ring) based upon ethtool alike
data parameter sepcification.

[dpdk-dev] [PATCH v13 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

[dpdk-dev] [PATCH v14 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v14 changes:
- Add library path to fix top-level, $RTE_TARGET, example/l2fwd-ethtool build
v13 changes:
- Rebase beause patch 1588
v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v14 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add two new apis: rte_eth_dev_default_mac_addr_set
and rte_eth_ethtool_dev_info to enable
reading device parameters (mac, register, eeprom,
pause, ring) based upon ethtool alike
data parameter sepcification.

It would be cleaner/clearer in a separate patch.
Why not using VALID_PORTID_OR_ERR_RET instead of rte_eth_dev_is_valid_port?

These functions should have the "get" word in their names.

The new symbols should be in a new node for DPDK 2.1.

[dpdk-dev] [PATCH v14 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

[dpdk-dev] [PATCH v15 0/4] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v15 changes:
- Replace rte_eth_dev_is_valid_port with macro VALID_PORTID_OR_ERR_RET
- Fix VALID_PORTID_OR_ERR_RET issue (unused macro variable)
- Fix api version map (move from 2.0 to 2.1)
v14 changes:
- Add library path to fix top-level, $RTE_SDK, example/l2fwd-ethtool build
v13 changes:
- Rebase beause patch 1588
v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (4):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v15 1/4] ethdev: add apis to support access device info

[Liang-Min Larry Wang]

add new apis:
- rte_eth_dev_default_mac_addr_set
- rte_eth_dev_get_reg_length
- rte_eth_dev_get_reg_info
- rte_eth_dev_get_eeprom_length
- rte_eth_dev_get_eeprom
- rte_eth_dev_set_eeprom

to enable reading device parameters (mac-addr, register,
eeprom) based upon ethtool alike
data parameter specification.

Is C always 0-base?
The offset is introduced because one of the review requesting to support partial register read, 
meaning reading single register or a set of registers.
As comment in my reply, this implementation only supports total register dump, 
but the data structure design allows future expansion to support this request.

Is there a document on such requirement?
I'm asking this question because different API's are added at different time.
Does this comment apply on relative order or absolute order meaning order relative to mainline code?

OK, so the comment should be something like "Offset in register table"

Not an excellent argument :)

No, only emails.
Every .map are alphabetically sorted. It's easier to check symbols.

Relative to mainline. Conflicts are handled when applying.

I could not speak for other devices. For igb and ixgbe, it's device id.
Based upon literature search, this field is used by device driver to provide extra information.
What would be your suggestion?

I don't have any suggestion.
You are defining a new API in DPDK, so our concern must be to check
that it will be easily understood by users and PMD developers.
If you don't really know what this field will be for, others won't know.

No, I meant it's device driver dependent. 
If I keep the same naming convention following kernel ethtool defined,
and adding comment like "device-specific magic key, such as device-id".
Would that be acceptable from you?
This data structure is defined to be compatible with kernel ethtool API,
and magic key is device specific and known to ethtool API users.

[dpdk-dev] [PATCH v15 4/4] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

[dpdk-dev] [PATCH v16 0/6] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v16 changes:
- Re-do patch v15 and separate changes between v15 and v14 into patch files 005 and 006
v15 changes:
- Replace rte_eth_dev_is_valid_port with macro VALID_PORTID_OR_ERR_RET
- Fix VALID_PORTID_OR_ERR_RET issue (unused macro variable)
- Fix api version map (move from 2.0 to 2.1)
v14 changes:
- Add library path to fix top-level, $RTE_SDK, example/l2fwd-ethtool build
v13 changes:
- Rebase beause patch 1588
v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (6):
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops
  examples: new example: l2fwd-ethtool
  ethdev: change api name, version information and fix macro
  examples/l2fwd-ethtool: replace lib with new API name

[dpdk-dev] [PATCH v16 4/6] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

Re: [dpdk-dev] [PATCH v16 0/6] User-space Ethtool

[Thomas Monjalon]

2015-07-14 09:11, Liang-Min Larry Wang:
> v16 changes:
> - Re-do patch v15 and separate changes between v15 and v14 into patch files 005 and 006

No, you misunderstood the need.
You must merge your fixes in appropriate patches.
But you must separate the mac_addr_set feature in another patch as it is
not related to ethtool dumps.

You are winning the record of patch iterations :)

Re: [dpdk-dev] [PATCH v16 0/6] User-space Ethtool

[Wang, Liang-min]

Thomas,
	The mac_addr_set is needed for ethtool net-op as described in examples/ethtool-ethtool/lib/rte_ethtool.c (rte_ethtool_net_set/get_mac_addr). Could you use the v15 for the release?

Larry

That's why it should be the first patch of this series.
You probably misread "another patch" which means different patch in same series.

> 	Could you use the v15 for the release?

No, there are more comments.

That's why this API and rest of API's added into librte_ether are all prepared in the same patch: 001.
I'm confused on your comment here. Are you asking me to break the patch 001 into two patches in the same series?
Meaning 001 and 002, would that be more confusing?

Yes exactly.

[dpdk-dev] [PATCH v17 0/5] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

v17 changes:
- Separate bug fix to a separate submission
- Separate rte_eth_dev_default_mac_addr_set implementation to a new patch file
- Change data structure names and comments
v16 changes:
- Re-do patch v15 and separate changes between v15 and v14 into patch files 005 and 006
v15 changes:
- Replace rte_eth_dev_is_valid_port with macro VALID_PORTID_OR_ERR_RET
- Fix VALID_PORTID_OR_ERR_RET issue (unused macro variable)
- Fix api version map (move from 2.0 to 2.1)
v14 changes:
- Add library path to fix top-level, $RTE_SDK, example/l2fwd-ethtool build
v13 changes:
- Rebase beause patch 1588
v12 changes:
- Update coding style to match latest change over rte_ethdev.c (by shemming@brocade.com)
v11 changes:
- Fixed a typo and clean coding style.
v10 changes:
- Merged const fix back to igb/ixgbe.
v9 changes:
- Fixed checkpatch errors.
v8 changes:
- Changed register tables to const.
v7 change:
- Remove rte_eth_dev_get_ringparam implementation
v6 change:
- Rebase to match new changes over librte_ether
v5 change:
- Change API name from 'leng' to 'length'
- Remove unused data structure rte_dev_vf_info
- Remove placeholder API rte_eth_dev_set_ringparam
- Clean up set_mac_addr implementation
v4 change:
- Add rte_eth_xxx apis and respective ops over igb and ixgbe
  to support ethtool and net device alike ops
- Add an example to demonstrate the use of ethtool library
v3 change:
- Fix a build issue
v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (5):
  ethdev: add api to support setting default mac addr
  ethdev: add apis to support access device info
  ixgbe: add ops to support ethtool ops
  igb: add ops to support ethtool ops

[dpdk-dev] [PATCH v17 1/5] ethdev: add api to support setting default mac addr

[Liang-Min Larry Wang]

add new api:
- rte_eth_dev_default_mac_addr_set

the new api, rte_eth_dev_default_mac_addr_set, uses the
existing dev_op, mac_addr_set, to enable setting mac
addr from ethdev level.

[dpdk-dev] [PATCH v17 5/5] examples: new example: l2fwd-ethtool

[Liang-Min Larry Wang]

The example includes an ethtool library and two applications:
one application is a non- DPDK process (nic-control)
and the other is a DPDK l2fwd applicaiton (l2fwd-app).
The nic-control process sends ethtool alike device management
requests to l2fwd-app through a named pipe IPC. This example
is designed to show how to build a ethtool shim library and
how to use ethtool apis to manage device parameters.

Signed-off-by: Liang-Min Larry Wang <liang-min.wang@intel.com>

The makefiles need some clean-up and it does not build in shared lib mode.

Applied without example which needs more work, thanks

Re: [dpdk-dev] [PATCH v17 0/5] User-space Ethtool

Thomas,
	Do you want me to create a separate patch just include the example/l2fwd-ethtool? Do you also mean besides the identified Makefiles, you see more rework needs to be done, or I just need to fix Makefile issue? If just Makefile issue, I could try to make another attempt tomorrow?

Thanks,
Larry

After checking the build there is probably more review to do.
Let's take more time to have something clean and maybe more complete in 2.2.
This patchset is your first contribution to DPDK and is already a nice achievement.
The new API must now be implemented in more drivers to be effective.

Re: [dpdk-dev] [PATCH v17 0/5] User-space Ethtool

[Wang, Liang-min]

Thomas,
	Thanks for clarification. Our next step is to create hooks on virtio and vmxnet3 and other ethtool op.

Thanks again for making prompt reply as I am aware it's very late in your time zone.

[dpdk-dev] [PATCH 0/2] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.
ethtool: adding new ethtool api support

v2 change:
- Implement rte_eth_dev_default_mac_addr_set through dev_ops::mac_addr_set so it would support NIC devices other than ixgbe and igb

Liang-Min Larry Wang (2):
  ethdev: add api to set default mac address
  ethtool: add new library to provide ethtool-alike APIs

[dpdk-dev] [PATCH 2/2] ethtool: add new library to provide ethtool-alike APIs

[Liang-Min Larry Wang]

adding a new library based upon ethdev APIs to provide API's that bear
the same functionality as ethtool_ops (linux/ethtool.h) and net_device_ops
(linux/netdevice.h).

NACK for several reasons:
- It's unclear what benefits this ethdev wrapper is bringing
- There is no obvious interest (how is it supposed to be used?)
- There is no update in the doc/ directory

Other comments:
- the patches are not versionned
- the copyright starts in 2010

I'm curious to understand how renaming rte_eth_dev_set_mtu() to
rte_ethtool_net_change_mtu() will help anyone.

Since ethtool is provided to assist users migrating from kernel ethtool/net_device_op based design to user-space DPDK device management. The ethtool API's are created to closely maintain its original interface, therefore this library depends on <linux/ethool.h>. To avoid pollute the existing ethdev interface, a new library is created. To minimize code replication and maintain closely 1:1 API definition with kernel space API, this interface is designed based upon available ethdev APIs and add additional dev_ops if it's necessary.

>- There is no obvious interest (how is it supposed to be used?)
There are already two acknowledge on this release. Earlier comment on this patch has that " ... The API's for ethtool like things are valuable ..."

>- There is no update in the doc/ directory
Need more guidance on that.

>Other comments:

There is version file. Not sure what do you mean "the patches are not versioned"

>- the copyright starts in 2010

Will fix that.

>rte_ethtool_net_change_mtu() will help anyone.

As described, this interface is designed to provide API closely to kernel space ethtool ops and net_device_op.

Re: [dpdk-dev] [PATCH 2/2] ethtool: add new library to provide ethtool-alike APIs

[Thomas Monjalon]

Wang, hope it's clear that any new development is welcomed.
One step before integration is to clearly explain why your code
is needed. That's why a nack vote may help to discuss and decide.

Stephen had some doubts about the real need and 2 people from Cisco
(who never contributed before) give their ack without justification.
Saying it's "valuable" or "very useful" is not enough.
A new library needs to demonstrate in which scenario the added-value is.
Sorry but you have to prove that it deserves to be maintained inside
the dpdk project.

You probably have to add a new chapter in the programmer's guide.

I mean there is no v2/v3 in the Subject. Please read

But the application still needs to adapt the code to call rte_* functions.
So changing to rte_ethtool_net_change_mtu is equivalent to change to
the existing rte_eth_dev_set_mtu. I don't see the benefit.

Not sure if the question is the usefulness of user-space ethtool (there was request for user-space ethtool @ dpdk.org last year, right, and Steve's comment ...) or the question on putting ethtool on separate library. For the latter concern, as described, the design is to avoid polluting ethdev library by this inevitable including <linux/ethtool.h>

>> >- There is no update in the doc/ directory

>You probably have to add a new chapter in the programmer's guide.

Sure, I would help doc team adding new section into programmer's guide and other if it's necessary. The first thing is to have this API approved for release first.

The benefit is single interface for users to access. Instead of looking into two different interfaces (ethtool, ether).

Sorry it doesn't help to understand.
Today, there is an ethdev API. Why adding an ethtool-like API would help?

Need to understand your specific concern. Do you oppose introducing new API to support ethtool ops and net_device_ops? 
Or your concern is on the implementation. If that's latter. 
Do you oppose adding a new library to implement ethtool ops and net_device_ops?
    If so, are you satisfied with my previous answer on avoiding polluting ethdev APIs? 
        If not, do you suggest integrating ethtool APIs into ethdev API?
    If not, is your concern on the implementation of common functionality between ethtool and ethdev APIs?
        If so, as explained, it is designed to provide a unified interface to assist users to migrate from kernel ethtool/net-device-op API to DPDK
BTW, as my reply to Steve's comment, more ops are on their way. This patch is to open up the interface.

I have the feeling we are not progressing in this discussion.
Please bring new explanations or I'll give up.
David Harton already acked it so maybe he could explain why it is useful.

They are not ethtool/netdev ops but fake ones.
In linux:
	int dev_set_mtu(struct net_device *dev, int new_mtu)
In dpdk:
	int rte_ethtool_net_change_mtu(uint8_t port_id, int mtu);
So yes, I'm opposed to add an API which is neither ethdev, neither ethtool.
But I may be missing an obvious justification.

Already answered above

No, it's better as a separate library.

Do you mean it would help migrating some code from kernel space to dpdk?
How it would help since the functions and data are different from the kernel ones?

Currently they are only some one-liners plus ethtool_drvinfo formatting
so there is no real benefit.
Why not wait to have more ops implemented?

So, the design purposely stays away from struct net_device to avoid carrying kernel states. We consciously choose port in place of net_device.
The kni already provides ethtool for kernel space code, this interface is designed for user-space application (fast-path comparing to kni).

For application that was designed based upon kernel-space ethtool-op and net-device-op, the user-space APIs provide a path for quick integration.

Due to amount of code change, I was advised to put into separate release and started with APIs that only requires minor changes on ethdev.
The rest of API requires changes on NIC pmd driver to support ops that are not currently supported.

Re: [dpdk-dev] [PATCH 2/2] ethtool: add new library to provide ethtool-alike APIs

[David Harton (dharton)]

Hi Thomas,

I think Larry explains things pretty clearly below.

A new application facing API is bring provided that avoids reusing kernel specific types and structs or dipping into the kernel itself.  It also clearly separates the user space API from driver related functions/types.

We do want to limit dipping into the kernel for performance reasons.

I hope this helps,
Dave

Re: [dpdk-dev] [PATCH 2/2] ethtool: add new library to provide ethtool-alike APIs

[Andrew Harvey (agh)]

I believe that their is value in this interface for software stacks not
based on Linux being moved toward DPDK that need simple operations like
getting the mac address.  Some of these stacks have a dearth of resources
available and dedicating a core/thread to KNI to get/set a mac address
is considered excessive. There are also issues with 32/64 bit kernel
integration
using KNI.  If the ethtool interface is not the correct interface then
please help me
understand what should/could have been used. If ethtool is considered 'old
and clunky¹
Stephen's and your input would be valuable in designing another interface
with
similar properties.  The use-case is pretty simple and there is no plans
for moving
anything back into the kernel on the contrary its the complete opposite.

Stephen, Thomas: I think it was the two of you that originally questioned the justification for including this change. Now that Andy and Dave Harton have clarified, does this resolve your concerns or do you still have questions? I just want to make sure that we reach a timely conclusion on this.

We have DPDK API's to do this, and any added wrappers make it bigger.
I don't see why calling your ethtool API is better than calling
rte_eth* API.

If there is a missing functionality in the rte_ethXXX api's for an
application then add that. For example: rte_eth_mac_addr_get()

I am getting somewhat confused by your latest comments.  Your first email
(referenced below) looked really positive and I found your suggestions
useful. Your latest post appears to contradict this and now the interface
was there all the time.  The wrapper façade provided by the ethtool
library provide a clean separation of concerns and will allow people to
migrate from not only KNI but in our case from a legacy system.  If a
software stack has requirements to work with multiple IO abstractions
then the ethtool approach is attractive. I would speculate that many
other stacks moving towards dpdk will have similar issues.

Summarizing, for our use-cases the ethtool interface facilitated our
adoption to dpdk while allowing us to support our legacy IO abstractions.

Stephen and me say the same thing about using the ethdev API.
We don't understand why using a fake ethtool lib would be easier.
Though you are saying it "facilitated [your] adoption to dpdk".
Please could you explain why using an ethtool-like API is easier than
using the existing ethdev API?
In any case, you have to develop a specific backend for DPDK
(rte_ethtool would be also DPDK-specific).

It seems you already started to use such an ethtool implementation.
Please note that our goal is not to prevent Cisco from upstreaming
(evidence with enic driver integration) but we want to guide you, and
others having the same needs, to the best solution for everybody.
That's why we need to understand what we (or you) are missing.
Maybe that it would be clearer with some code examples (which would
go in the lib documentation if any).

Thanks

As described earlier in this patch comment reply, there are other ethtool ops that have been implemented.
Those ops includes set/get eeprom, set/get pauseparam, set/get ringparam which are not available in the exiting ethdev library.
For this release, we focus on releasing some basic functions (btw, mac_addr_set is not available but is covered by this patch).
The key reason that this set of library is not released as part of ethdev is the ethtool API dependency on kernel include file.
To faithfully carry the ethtool ops and net dev ops API parameters, the ethtool APIs are designed to follow the original definition except avoiding carry kernel states.
With that, to support ethtool APIs faithfully, we need to include <linux/ethtool.h>. 
As suggested by many DPDK veterans including Thomas (indicated over your reply), you would prefer these APIs in a separate library.

How about doing this work as a sample application initially, to demonstrate how
an application written using ethtool APIs could be shimmed to use DPDK underneath.
The ethtool to dpdk mapping could be contained in a single header file (or header
and c file) inside the sample app. This would allow easy re-use of the shim
layer, while at the same time not making it part of the core DPDK libraries.

This would appear to be the most pragmatic way forward.  It would allow
others to see more of the code and judge its value for themselves. I have
no issues with this approach if others agree.

Since the beginning of this thread, a doc is requested (many times) to
show the benefit of integrating such a layer.
If you prefer coding a full example, it would probably also be fine.

1/ We cannot really consider code which is not public
2/ You may extend ethdev if some functions are missing

> For this release, we focus on releasing some basic functions (btw, mac_addr_set is not available but is covered by this patch).

Yes, you are extending ethdev by adding rte_eth_dev_default_mac_addr_set.

> The key reason that this set of library is not released as part of ethdev is the ethtool API dependency on kernel include file.

It is a good reason to separate the library.
But it doesn't justify its need.

I think I'm starting to understand that you really need ethtool conversion
(implemented in rte_ethtool_get_drvinfo) but not the other functions which
are simple wrappers. Right?

The rte_ethtool_get_drvinfo and many others ethtool ops have the same conversion requirement.
As for ethtool and net dev ops that don't require conversion. For the sake of clean API interface, they are implemented in the same ethtool library.

And your would have a point would be valid if dpdk were available to every
interface we support (it is not) and on every processor architecture that
we support (it is not) and every OS we support (it is not).  So to
minimize entropy in the code why not leave the client code the same
ioctl(fd, …) and hide the implementation
detail in a wrapper library.  We have a large legacy code base to move
forward and sprinkling special interest code like rte_xxx throughout every
client we have is not appropriate at this time.

Please, explain the relation between an ioctl and the DPDK.

[dpdk-dev] [PATCH 0/2] User-space Ethtool

[Liang-Min Larry Wang]

This implementation is designed to provide a familar interface for applications that rely on kernel-space driver to support ethtool_op and net_device_op for device management. The initial implementation focuses on ops that can be implemented through existing netdev APIs. More ops will be supported in latter release.

Providing a hook to access more functionality is good and compatiablity
with old API's is helpful.  Too bad ethtool is kind of a clunky old
inflexible, and easily broken with changes. But that is not your fault.

Duplicating eth_stats in ethtool is not helpful.
This is actively discouraged for Linux device drivers.

(I have a typo of David's email, and I corrected it in this email)
This new library is designed to support ethtool alike interface, some of the implementation will be just a placeholder. The rte_ethtool_net_get_stats64 is designed as a place holder to support net_device_ops::ndo_get_stats64. For the legacy support, it is required to provide # of statistic parameters are supported, so caller can allocate right size of buffer to get statistic from device driver.
