amdgpu and kernels newer than 5.2 - video issues

[milomak]

so i have noticed that i get the below when trying to upgrade to kernels newer than 5.2

inxi -F reports my graphics as being

i have also noticed hat the boot time is significantly slower and sometimes i am unable to boot into a number of desktop environments without error

i have tried to to find what could be the cause and i am wondering whether the card is just too old and support has been dropped for it since the last kernel that worked for me

Code: Select all

5.2.0-21.2-liquorix-amd64

i have tried the vanilla kernels and they also prop up the same errors. the latest being

Code: Select all

linux-image-5.7.0-1-amd64

i have tried many solutions that require pulling git repositories but these have not helped these particular files

You should probably post these mysterious errors. Or enter them into a search engine, which may be quicker than awaiting a reply here.

The messages in your first code block are warnings rather than errors and some of them refer to firmware for which the hardware hasn't been released yet. AMD like to get ahead of the game and will submit drivers early.

Please share these failed solutions so we don't waste our time posting links to https://git.kernel.org/pub/scm/linux/ke ... ree/amdgpu or the like.

fair

so my video issues start from the first instance i start getting these errors. hence why i ask whether it may be the case that my particular card is no longer supported.

in your link you will see that for instance the first file posted as a warning in my op navi12_gpu_info.bin is not in the link you provide

i have gone through may links that purport to talk this issue but don't have these files

As a general rule the Linux developers do not remove support for hardware but regressions are unfortunately common so perhaps try https://wiki.debian.org/DebianKernel/GitBisect

navi12_gpu_info.bin is not in the link you provide

That firmware doesn't seem to be available yet but neither is the hardware for which it is required (AFAIK).

You should also make it clear that you're using Sid/Bullseye or (hopefully not) a FrankenDebian, since llvm-10 is not availabe in stable or stable-backports, which introduces its own set of complications.

i thought my signature sorted that out

but i'll take the point that people don't necessarily look at them

[stevepusser]

Maybe do some graphic benchmarks between the different kernels to see if performance is degraded. The firmware warnings are just because the Debian firmware is a year old now and far behind the kernels, but your GPU is not outdated and the warnings can be ignored in your case.
