Subject: [Intel-wired-lan] [iwl-next v4 0/8] ice: support devlink subfunction
Date: Wed, 17 Apr 2024 16:20:20 +0200 [thread overview]
Message-ID: <20240417142028.2171-1-michal.swiatkowski@linux.intel.com> (raw)
Hi,
This is second patchset split from subfunction patchset [1].
Important changes from previous version:
* remove unnecessary checks for devlink port type
* link correct devlink port to subfunction netdev
Follow up patchset with subfunction port representor will be the last
patchset for subfunction implementation in ice. It is a little
unpleasant to split it like that, because devlink port should be linked
with port representor netdev. In this patchset use devlink port without
linking it. It will be done correctly in the follow up when subfunction
port representor is available.
Currently ice driver does not allow creating more than one networking
device per physical function. The only way to have more hardware backed
netdev is to use SR-IOV.
Following patchset adds support for devlink port API. For each new
pcisf type port, driver allocates new VSI, configures all resources
needed, including dynamically MSIX vectors, program rules and registers
new netdev.
This series supports only one Tx/Rx queue pair per subfunction.
Example commands:
devlink port add pci/0000:31:00.1 flavour pcisf pfnum 1 sfnum 1000
devlink port function set pci/0000:31:00.1/1 hw_addr 00:00:00:00:03:14
devlink port function set pci/0000:31:00.1/1 state active
devlink port function del pci/0000:31:00.1/1
v3 --> v4: [4]
* get rid of unnecessary checks
* fix cosmetic issues (whitespaces, wording)
* move unrelated chunks to separate patch
* move implementing activation/deactivation to last patch
v2 --> v3: [3]
* fix building issue between the patches; allocating devlink for
subfunction need to include base subfunction header
* fix kdoc issues
v1 --> v2: [2]
* use correct parameters in ice_devlink_alloc() thanks to Mateusz
