Note for anyone who has a Polaris GPU (Radeon RX 5xx) debugging issues with this package; Packages that use OpenCL like clinfo or davinci-resolve-studio will need you to downgrade opencl-amd to 1:5.7.1-1 as well as amdgpu-pro-oglp to 23.10_1620044-1 to avoid coredumps & segfaults.

DVR would not open unless these 2 packages were downgraded (along with their dependencies). Had to figure it out the hard way after hours using valgrind and rebooting over and over. Hopefully someone else will not have to pull their hair out trying to resolve their issue.

@lucciddream No problem, I'll stick to 20.40. Happy to test when a new version comes out :)

@hpohl If 20.40 works for you but 20.50 doesn't, my guess is that ROCM might not be supporting 6700XT yet. But I would wait for more people to comment and verify that. AMD promised zero day support for ROCM and RDNA2, and that was my main motivation when I updated the package, but I'm not sure they have been able to keep that promise.

Blender does not list my RX 6700 XT as an OpenCL device.

@ATrigger and @quimkaos can you read the pinned comment? Need some info from Polaris card users so yea

@hpohl geekbench5, Blender (with OCL turned on), LibreOffice (with OCL turned on)

@sperg512 Do you have an example of a game or benchmark that uses OpenCL? Preferably free :)

I've just installed 20.40 and it works:

@hpohl run ldd -v /usr/bin/clinfo and paste the output, maybe some library is missing for 6700 XT.

@hpohl that's interesting. Do apps/games that use OpenCL crash without DRI_PRIME=1? If so, then get one to crash and attach a crash log of that game and the most recent (or any relevant) dmesg lines.

My RX 6700 XT is not detected by clinfo (with our without --ofline):

Also there is a new build (1234664) available, but it did not change anything. And so did downgrading to 20.45.

Running games with DRI_PRIME=1 works just fine.

0b:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 22 (rev c1)

Could not find anything relevant in dmesg.

Tell me if you need any more info :)
