[dpdk-dev] [PATCH v7 00/28] remove pci driver from vdevs

[dpdk-dev] [PATCH v7 00/28] remove pci driver from vdevs

[Bernard Iremonger]

There is a dummy pci driver in the vdev PMD's at present.
This patch set removes the pci driver from the vdev PMD's.
Changes have been made to librte_ether to handle vdevs and pdevs in the same way.

The following vdev PMD's have had the pci driver removed:

null
ring
bonding
pcap
af_packet
xenvirt
mpipe

All the pdev PMD's have been modified to copy the pci device info into eth_dev data.

Changes in v7:
rebase to latest code.

Changes in v6:
Initialise data->drv_name with the PMD driver name in the vdevs.
Remove two more branches on pci_dev from the bonding vdev.

Changes in v5:
rebase to latest code.
refactor patches to avoid potential problems with git bisect.

Changes in v4:
rebase to latest code.
add doxygen comments to rte_ethdev.h
update release notes in patch 0002.

Changes in v3:
rebase to latest code.
restructure patches 0002 and 0003 to fix compile issue in patch 0002.

Changes in V2:
rebase to latest code.
fix compile error in rte_ethdev.c when debug disabled.
remove Intel copyright from bnx2x, cxgbe, enic, mlx4, mpipe and null PMD's.

Bernard Iremonger (28):
  librte_eal: add RTE_KDRV_NONE for vdevs
  librte_ether: add fields from rte_pci_driver to rte_eth_dev_data
  librte_ether: add function rte_eth_copy_dev_info

Please Bernard, be kind and change the status of your previous patchset.
I'm tired to do it for 28 patches each time you rebase.
By the way, it is not needed to do a patch per driver when it is the
same oneliner without any explanation message.

Why it is not a private data of the bonding device?
Why the check on the device name is not relevant anymore?

Please, use an enum which has a name and can be referenced in the API,
e.g. the variable X contains some X_flags.
You should not try to re-use the same values as the PCI layer since it
will not be possible to map it forever when new buses will enter in the game.

Why not having RTE_ETH_DEV_PCAPED? ;)
Please try to remove this flag.

Re: [dpdk-dev] [PATCH v7 00/28] remove pci driver from vdevs

[Qiu, Michael]

Hi, Bernard

Could we merge some patch together? I see lots of patches are simple and
doing the same thing but in different NIC, merge them almost have no
affect of review, what's more it will make reviewers more comfortable
with less and simple patches.

Then we could have a clean patch set with almost 5 patches, not totally 28.

librte_eal: add RTE_KDRV_NONE for vdevs
librte_ether: add fields from rte_pci_driver to rte_eth_dev_data
drivers: copy pci device info to eth_dev data
librte_ether: remove branches on pci_dev
drivers: remove pci device

At least, we could merge serial patches "xxxx:copy pci device info to
eth_dev data" to "drivers: copy pci device info to eth_dev data" in my mind.

Just an advise, but better to have.

Thanks,
Michael

I mean it should be more explicit. Having an enum name will help.
Note: I understand your patch. I'm just asking the questions an user
will ask when trying to use your new API.

I will try to be clearer in the commit message.
I tried an enum for the dev_flags but it does not work well.
There can be multiple flags set in dev_flags, it is intended to be a bit field similar to the pci flags.

I have squashed down to 19 patches now, I don't want to over squash.

Bernard.

Yes. You can assign some bits in an enum.
But if you prefer the defines, it's also OK if they are clearly identifiable:
with a prefix and good comments allowing to map the structure field and the flags.

The proposal of 5 patches was good.
