Both register/unregister and enable/disable don't necessarily require the

Not being picky - but, multiple Acked-by can be removed when this is

To: dev; +Cc: Stephen Hemminger, shreyansh.jain, david.marchand, Stephen Hemminger
From: Stephen Hemminger <stephen@networkplumber.org>
Since later changes will change where PCI information is,
localize mapping in one macro.

This adds a helper to get the rte_intr_handle from the virtio_hw. This is
safe to do since the usage of the helper is guarded by RTE_ETH_DEV_INTR_LSC
which is only set if we found a PCI device during initialization.

Since intr_handle is already an argument to interrupt handler, why not use it?
That is what I did in the Intel driver changes.

We don't need to depend on rte_eth_dev->pci_dev to differentiate between
the virtio_user and the virtio_pci case. Instead we can use the private
virtio_hw struct to get that information.

Why adding this function instead of just using DEV_PCI_DEV(eth_dev->device)?
I think we must try to avoid any PCI (or other bus) reference inside ethdev.h.

David requested to move it from rte_pci.h to rte_ethdev.h.
It could get forward declared here if one doesn't use it. On the other
hand the rte_pci.h would be required to include rte_ethdev.h if we
move it.

I think there is a misunderstanding.
I was just suggesting to drop this function.

But that would undo the whole purpose of adding a helper. The purpose
of the helper is to map from ethdev to the low-level rte_pci_device.
If we remove this helper all users still need to know how to map to
the embedded device structure. What you ask for also means that the
patch "ethdev: Decouple struct rte_eth_dev from struct rte_pci_device"
needs to change all users of the DEV_PCI_DEV() instead of changing the
helper introduced in this patch.
Let me summarize the workable options from my perspective:
1. helper macro to map from eth_dev to pci_dev in rte_pci.h
2. helper inline function to map from eth_dev to pci_dev in rte_ethdev.h
3. put helpers into new header file rte_ethdrv.h
I'm still in favor of the first option but David suggested to remove
it from eal. I could also counter the type-safety argument from
Stephen by adding a type check to it.

Yes, using RTE_PCI_DEV(eth_dev->device) instead of rte_eth_dev_to_pci(eth_dev).
Is it a problem to know that the field name is "device" to access the
underlying device characteristics?

My proposal is:
4. no helper, use eth_dev->device

Instead of duplicating this macro with different names lets use the helper
provided by ethdev.

To: dev; +Cc: shreyansh.jain, david.marchand, stephen
The drivers should not directly access the rte_eth_dev->pci_dev but use
a helper instead. This is a preparation for replacing the pci_dev with
a struct rte_device member in the future.

I would still like to kill dev_pci from the dev_info API.

+1. It should be rte_dev reference instead.
(But, I am also OK about doing that immediately over this set.)

Only if you can give use-cases for what users should be able to do
with it. If that is the case we need to clearly define what that
means. Do we want to enable users to control the low-level EAL device
directly and shortcut the ethdev driver? If that is necessary we need
to give control to the driver first to decide if it is safe to do so.

An ethernet device is not necessarily a PCI device. With planned removal
of rte_pci_device from rte_eth_device, this will be realized.
Similarly, the info is also not PCI device specific.
With the '+1', my intention was not to say we should do it in this
patch. We should prepare eth_dev_info in similar manner as done for
pci_dev of rte_eth_dev (ETH_DEV_PCI_DEV() style macro, or inline).
And now for whether we should expose lower level device details or not,
I was of the view that keeping pci_dev linked to this structure exposes
more lower level info than keeping rte_dev. Another view point could be
to completely do away with pci_info within eth_dev_info - but, I am not
sure of dependencies on it.

The struct rte_intr_handle is an abstraction layer for different types of
interrupt mechanisms. It is embedded in the low-level device (e.g. PCI).
On allocation of a struct rte_eth_dev a reference to the intr_handle
should be stored for devices supporting interrupts.

Why adding interrupt in ethdev?
Shouldn't it be a property of rte_device?

Good question. I don't think that rte_device should become an
abstraction layer for all kind of real/virtual devices functionality.
There are devices that do not support interrupts and this
functionality is around enabling irqs per queue. Since this is a
concept of the ethdev I believe the right place to keep a reference to
the IRQ implementation is the rte_eth_dev.

I think it would easier to read if RTE_PCI_DEV macro was introduced at
the beginning with container_of macro and used in the "localize patches".
So the patches
[PATCH v4 19/23] drivers: Replace per-PMD macros with rte_eth_dev_to_pci() helper
and
[PATCH v4 20/23] drivers: Use rte_eth_dev_to_pci() helper
could be squashed in the "localize patches".

After a private discussion, I've understood that my proposal was stupid :)
RTE_PCI_DEV is used when the ethdev field is converted from pci_dev to device.

This repost addresses the review comments of Thomas Monjalon to completely
remove the ethdev helper to further decrease the coupling of the ethdev and
the eal layers. This required me to squash together all patches using the
rte_eth_dev_to_pci() helper into "Decouple from PCI device" patch. As
discussed privately I'll keep the PCI information in rte_eth_dev_info
untouched.
Changes between v5 and v4:
- Removed ethdev helper rte_eth_dev_to_pci()
Changes between v4 and v3:
- broken out refactorings of drivers similar to Stephens example
- use inline function instead of macro
- fix build issues with bnx2x and mlx4/5
Changes between v3 and v2:
- converted PCI device users I've missed in previous version
Jan Blunck (14):
eal: define container_of macro
eal: Allow passing const rte_intr_handle
virtio: Don't fill dev_info->driver_name
virtio: Add vtpci_intr_handle() helper to get rte_intr_handle
virtio: Don't depend on struct rte_eth_dev's pci_dev
bnx2x: localize mapping from eth_dev to pci
fm10k: localize mapping from eth_dev to pci
qede: localize mapping of eth_dev to pci
szedata2: localize handling of pci resources
nfp: localize rte_pci_device handling
vmxnet3: use eth_dev->data->drv_name instead of pci_drv name
ethdev: Decouple interrupt handling from PCI device
ethdev: Move dev_info filling of PCI information into drivers
ethdev: Decouple from PCI device

Both register/unregister and enable/disable don't necessarily require the
rte_intr_handle to be modifiable. Therefore lets constify it.

See "src" instead of intr_handle is used here. "src" is only initialized as calling rte_intr_callback_register at device init phase. But max_intr is usually changed as calling rte_intr_efd_enable() after that. How to make sure max_intr in "src" is valid? And, why shall we use src instead of intr_handle here?
Thanks,

Go ahead and add missing signed-off-by. I overlooked it on the

Since rte_eth_dev_info_get does memset() on dev_info before
calling device specific code, the explicit assignment of NULL
in all these virtual drivers has no effect.

To: dev; +Cc: Stephen Hemminger, shreyansh.jain, david.marchand
From: Stephen Hemminger <stephen@networkplumber.org>
Create one macro for where PCI device information is extracted
from ethernet device. Makes later changes easier to review, and test.

Go ahead and add missing signed-off-by. I overlooked it on the
original RFC set.

This adds a helper to get the rte_intr_handle from the virtio_hw. This is
safe to do since the usage of the helper is guarded by RTE_ETH_DEV_INTR_LSC
which is only set if we found a PCI device during initialization.

We don't need to depend on rte_eth_dev->pci_dev to differentiate between
the virtio_user and the virtio_pci case. Instead we can use the private
virtio_hw struct to get that information.

Use device private information to minimize the places that assume eth_dev
contains pci_dev.

The struct rte_intr_handle is an abstraction layer for different types of
interrupt mechanisms. It is embedded in the low-level device (e.g. PCI).
On allocation of a struct rte_eth_dev a reference to the intr_handle
should be stored for devices supporting interrupts.

Only the drivers itself can decide if it could fill PCI information fields
of dev_info.

To: dev; +Cc: shreyansh.jain, david.marchand, stephen
This makes struct rte_eth_dev independent of struct rte_pci_device by
replacing it with a pointer to the generic struct rte_device.
