Missing amdgpu firmware files

Missing amdgpu firmware files

[Seth Forshee]

I've received reports from Ubuntu users about missing amdgpu firmware
files with 4.2 kernels. The driver calls out a number of
radeon/*_sdma1.bin files that are not present in the linux-firmware git
repo. Are these files available anywhere (under a license that allows
redistribution), and will they be pushed up to linux-firmware anytime
soon?

Thanks,
Seth

Well that's strange. Essentially those are just duplicates to the 
existing files and the driver should fallback to them.

IIRC the radeon/*_sdma1.bin files are only requested when you try to use 
CIK support with amdgpu which isn't a good idea in a production environment.

What's the link for the bug reports? It's most likely just people trying 
to use the driver with hardware which it isn't supposed to be used with.

We probably should either remove CIK support totally from the amdgpu or 
add all the files to the firmware repository.

Regards,
Christian.

Exactly.  They are only used if you forcibly enable CIK support in amdgpu which is just for testing.  CIK is already supported in radeon and that should be used for CIK parts.  Sdma1 is identical to regular sdma file so you can just symlink them or copy them.  I guess I can update the firmware tree.

There have been a few reports that the firmware is missing, but only one
I see where the user actually reports any display problems.

 http://bugs.launchpad.net/bugs/1510405

Of course it's possible that he is jumping to conclusions about the
missing firmware files causing his display issues.

Thanks,
Seth

The driver refuses to load if the firmware is missing.  However, as Christian mentioned, you will only get those messages if you've enabled CIK support amdgpu which we don't recommend (controlled by CONFIG_DRM_AMDGPU_CIK).  Radeon does not require the additional firmware.

Got it, thanks. I'll disable it.
