[PATCH] ethdev: replace bus specific struct with generic dev

[PATCH] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

There is no deprecation notice sent for this update but in this release
ethdev info already updated and ABI already broken, it can be good
opportunity for this update.

[PATCH v2] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assinged to NULL, fixed them

[PATCH v3] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assigned to NULL, fixed them

v3:
- rebased on latest next-net

The ethdev device already points to the backing device.
So, can't this be done in the ethdev layer itself ?

Thanks Dave, yes, I think can be done. I will update according.

[PATCH v4] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assigned to NULL, fixed them

v3:
- rebased on latest next-net

v4:
- Move dev_info->device assignment to ethdev layer

Just a little comment, do we want the pmd to be able to override this ?

I can see we enforce the driver name by putting it after the call to
.dev_infos_get.
http://dpdk.org/browse/dpdk/tree/lib/librte_ether/rte_ethdev.c#n2399

octeontx pmd seems to try to do something about it:
http://dpdk.org/browse/dpdk/tree/drivers/net/octeontx/octeontx_ethdev.c#n622

Not sure it does something, might be a thing to cleanup.

I still don't see when the pmd would need to override the dev_info->device.
The pmd is the one that populated dev->device in the first place.

Why would it want to report something different in dev_infos ?
Some comments from pmd maintainers, maybe ?

In case, if your referring to driver_name update then
indeed its a cleanup [1].

Otherwise, I don't see any issue with v4 Or

I agree there is no fundamental issue.

    dev_info->device = dev->device;

    RTE_FUNC_PTR_OR_RET(*dev->dev_ops->dev_infos_get);
    (*dev->dev_ops->dev_infos_get)(dev, dev_info);
    dev_info->driver_name = dev->device->driver->name;

If somebody (I mean some pmd out there) has a usecase with
dev_info->device != dev->device, why not.

Intentional let drivers update this variable although I don't also see any use
case of it.

This variable was set by PMDs before this patch, so I don't see any reason to be
so strict here.

If driver does anything ethdev will set dev_info->device for it, if it want to
overwrite, for any reason, it will have the capability.

Looks good to me. Will do the same for cryptodev and bbdev.
The only thing that I am missing here is an update in documentation,
adding the ABI Change in release notes.

Right, I forget about it, will send a new version.

[PATCH v5] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assigned to NULL, fixed them

v3:
- rebased on latest next-net

v4:
- Move dev_info->device assignment to ethdev layer

v5:
- Document API change in related section in release notes

[PATCH v6] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assigned to NULL, fixed them

v3:
- rebased on latest next-net

v4:
- Move dev_info->device assignment to ethdev layer

v5:
- Document API change in related section in release notes

v6:
- Rebase on latest next-net, ip_pipeline updated
- Update axgbe too
