I have a pretty old laptop with an AMD dGPU and I am trying to do OpenCL compute on it to make sure that device switching is handled correctly in some stuff I am testing. All the instructions I see to install amdgpu drivers is to have --no-dkms as an install flag.
Doing
amdgpu-install --usecase=opencl --no-dkms --opencl=legacy
results in
ERROR: using '--no-dkms' with '--opencl=legacy' is not supported
Specs:
HP Pavilion 15-br158cl
CPU: i7-8550u (HD 620 iGPU and this has working compute)
GPU: Radeon 530 2 GB DDR3
RAM: 24 GB
OS: PopOS 22.04 6.12.10-76061203-generic
Clinfo -l output
Platform #0: Intel(R) OpenCL HD Graphics
-- Device #0: Intel(R) UHD Graphics 620 [0x5917]
Platform #1: AMD Accelerated Parallel Processing
As you can see, only the platform, not a second device. Is there anything that I am missing?
I did post this on reddit in the PopOS subreddit. https://www.reddit.com/r/pop_os/comments/1kvza44/is_there_a_way_to_use_amdgpudkms_without_bricking/
IDK what did you mean by “their own thing”. Even if they created something similar to dkms, it is unlikely that it would conflict with dkms. But anyway it is better to find more information from official source.
