Using AMDGPU.jl with an AMD APU

Specific Domains GPU
1

I was trying AMDGPU.jl with an AMD APU. I was convinced that ROCm did not support APU’s, but this thread gave me hope that it might work.

I have a desktop with a Ryzen 4750G APU. I am running linux (Kubuntu 21.10 with a 5.17 kernel), with Julia version 1.7.3, AMDGPU.jl v0.3.3

So far, I have not been successful.

I get the following warning:

julia> using AMDGPU

If I try to build the package, I get:

If I test the package,

(@v1.7) pkg> test AMDGPU

I obtain:

Has anyone encountered this before?

What permissions are on /dev/kfd and /dev/dri/*? This error often comes from having insufficient permissions to open those devices with read+write access.

Thank you for your reply. These are the premissions of those files/folders:

Do you have both the video and render groups assigned to your user? If so, these look fine to me.

That was probably the problem. My user was not listed as a member of the video and render groups. I added my user to those groups and the warnings went away!

Thanks a lot @jpsamaroo !

Now its time to explore how things work with the APU.
