Bug#918009: firmware-amd-graphics: please add amdgpu firmware for kaveri

[Trek]

Version: 20180825+dfsg-1

I confirm the problem, it leads to a crash of the amdgpu module if the
4.19 kernel is booted with amdgpu.cik_support=1 radeon.cik_support=0

for further informations see

https://bugs.freedesktop.org/show_bug.cgi?id=107855

comment 2 for the kernel messages and comment 4 for a simple workaround

however the correct solution is to include the amdgpu firmware, as the
radeon firmware seems to be no more updated

ciao!

Bug#918009: firmware-amd-graphics: please add amdgpu firmware for kaveri

[Abderrahim Kitouni]

Package: firmware-amd-graphics
Version: 20181218-1
Severity: important

Dear Maintainer,

Kaveri APUs, along with other SI and CIK parts, still uses the radeon driver
by default. They can also use the amdgpu driver by setting some options.

In linux 4.19 at least, the amdgpu driver doesn't load the firmware in
radeon/kaveri* anymore, and expect it to be found in amdgpu/kaveri* instead.

Looking at the linux-firmware repository, it seems that the firmware is
different. For instance:

$ sha1sum */kaveri_pfp.bin 
bddd0dda7153a549602b2b339c7f2de507815bc8  amdgpu/kaveri_pfp.bin
d0033d1be4f137d7ec96c9ab2b4a2976d6b4c9f3  radeon/kaveri_pfp.bin


I think other hardware from those families deserve the same treatment. If I'm
not mistaken, this includes bonaire, hainan, hawaii, kabini, mullins, oland,
tahiti and cape verde.


Cheers,

Abderrahim
