From: Alejandro Lucero <alejandro.lucero-palau@amd.com>
v6 changes:
- add file headers at its due time
- fix sfc.rst warnings
- add sfc.rst to the index.rst file
- avoid microblaze build error
- simplify devlink info errors reported
v5 changes
- add extack error report for devlink info
- Rename devlink functions stating locking
- Check functions return through a variable
- Remove unnecessary non related changes
- put SRIOV dependent code inside #ifdefs (is ia64 still alive?)
v4 changes:
- Add new doc file to MAINTAINERS
- nvram metadata call independent of MTD config
- add more useful info with extack
v3 changes:
- fix compilation warnings/errors reported by checkpatch
v2 changes:
- splitting up devlink info from basic devlink support
- using devlink lock/unlock during initialization and removal
- fix devlink registration order
- splitting up efx_devlink_info_running_versions
- Add sfc.rst with specifics about sfc info
- embedding dl_port in mports
- using extack for error reports to user space
This patchset adds devlink port support for ef100 allowing setting VFs
mac addresses through the VF representor devlink ports.
Basic devlink infrastructure is first introduced, then support for info
command. Next changes for enumerating MAE ports which will be used for
devlink port creation when netdevs are registered.
Adding support for devlink port_function_hw_addr_get requires changes in
the ef100 driver for getting the mac address based on a client handle.
This allows to obtain VFs mac addresses during netdev initialization as
well what is included in patch 6.
Such client handle is used in patches 7 and 8 for getting and setting
devlink port addresses.
Alejandro Lucero (8):
sfc: add devlink support for ef100
sfc: add devlink info support for ef100
sfc: enumerate mports in ef100
sfc: add mport lookup based on driver's mport data
sfc: add devlink port support for ef100
sfc: obtain device mac address based on firmware handle for ef100
sfc: add support for devlink port_function_hw_addr_get in ef100
sfc: add support for devlink port_function_hw_addr_set in ef100

From: Alejandro Lucero <alejandro.lucero-palau@amd.com>
Obtaining mport id is based on asking the firmware about it. This is
still needed for mport initialization itself, but once the mport data is
now kept by the driver, further mport id request can be satisfied
internally without firmware interaction.
Previous function is just modified in name making clear the firmware
interaction. The new function uses the old name and looks for the data
in the mport data structure.

Using the data when enumerating mports, create devlink ports just before
netdevs are registered and remove those devlink ports after netdev has
been unregistered.

From: Alejandro Lucero <alejandro.lucero-palau@amd.com>
Getting device mac address is currently based on a specific MCDI command
only available for the PF. This patch changes the MCDI command to a
generic one for PFs and VFs based on a client handle. This allows both
PFs and VFs to ask for their mac address during initialization using the
CLIENT_HANDLE_SELF.
Moreover, the patch allows other client handles which will be used by
the PF to ask for mac addresses linked to VFs. This is necessary for
suporting the port_function_hw_addr_get devlink function in further
patches.

Using the builtin client handle id infrastructure, add support for
obtaining the mac address linked to mports in ef100. This implies
to execute an MCDI command for getting the data from the firmware
for each devlink port.

Using the builtin client handle id infrastructure, add support for
setting the mac address linked to mports in ef100. This implies to
execute an MCDI command for giving the address to the firmware for
the specific devlink port.

Just wondering if this single nit deserves a v7 or better to delay it as
another patch.
We got another patchset for ef100 ready to be sent and we would prefer
to not delay this one more than needed.

I don't get this SRIOV dependency. In the cover letter you say it
was because of IA64, bu those errors were:
ia64-linux-ld: drivers/net/ethernet/sfc/ef100_nic.o: in function `ef100_remove':
ef100_nic.c:(.text+0x2e82): undefined reference to `efx_ef100_fini_reps'
ia64-linux-ld: ef100_nic.c:(.text+0x2e92): undefined reference to `efx_fini_mae'
which is completely unrelated to this patch.
This extra ifdef must not be needed at all. I suspect something else
is going wrong in your builds.
Please explain in detail why you think you need this.

This is not due to the ia64 build errors but due to the microblaze build
errors.
We are using rtc_time64_to_tm twice in the info related code which turns
out to be not available for Microblaze.
I did take a look and not found a quick way of substituting those calls.
SRIOV is not configured for Microblaze and I guess it will never be.
This change makes the devlink info command not available if SRIOV is not
configured which is arguably not a big problem. It can be said the
device info could be useful in that case what I really doubt. Yes, a
netdev for the PF can be used, but what do we need devlink for then? Our
firmware installation/setup is not based on devlink and we have other
means for obtaining firmware related info.
IMO, Microblaze should have not ef100 configured ...
