Re: Freeing Machine Learning with ROCm

Hi Zacchaeus,

I packaged ROCm for Guix.

Indeed, I am using Guix’ darktable and rocm-opencl-runtime packages
for OpenCL-accelerated photo editing. But I’m also doing this on a
foreign distribution with a custom kernel (5.15) – not Guix System.

Which GPU are you using? Can you see it with `lspci` and does it have the
`amdgpu` driver attached? Is the firmware loaded (`dmesg | grep amdgpu`,
I’m guessing no, since you use linux-libre)?

rocminfo does not show the card’s temperature. You need this[1]
(unpackaged) tool.
