RyzenAI APU not recognized in LXC
Hello,
I have an Arch host running LXC. the host has an AMD Ryzen 7 8700G, which has a gfx11 GPU and a RyzenAI APU integrated.
I installed rocm-hip-runtime both in the host and the guest systems, and rocminfo gives me different results: the container is missing the APU, which shows in the host as "Agent 3".
I have /dev/dri and /dev/kfd bind-mounted on the container. Do I need any other arrangement to access the APU from the container?
This is the output of "rocminfo" on the host. The container essentially lacks the third "agent" entry.
ROCk module is loaded

Re: RyzenAI APU not recognized in LXC
Which os, kernel version and firmware are you running inside of the guest?

Re: RyzenAI APU not recognized in LXC
I'm running an up-to-date Arch, same as the host. Kernel is 6.17.13-hardened1-3-hardened
On the host, I have linux-firmware 20260221-1 and linux-firmware-amdgpu 20260221-1 installed. I did NOT have that installed in the guest, but even installing those doesn't change the rocminfo output.

Re: RyzenAI APU not recognized in LXC
Could you try it on the regular (non-hardened) kernel? Also note that you'll need a kernel newer than 7.0rc2 (or the DKMS thingy) to do anything useful things with the NPU https://fastflowlm.com/docs/install_lin/#runtime-stack

Re: RyzenAI APU not recognized in LXC
I see. It's not easy to upgrade the kernel right now as LXC inherits it from the host, which is now running a dozen other live services (hence the hardened version).
I will wait until 7.0-hardened is released in the Arch extra repo to test again, or I'll fiddle with DKMS (I'm not familiar with this area so I don't know if I can do that within the guest). Thanks for the advice. I'll report back in due time.
