Unable to access OpenCL device in Jellyfin LXC container on AMD

[randomuser1990]

Hello,

I'm running Proxmox 7.3-6 with an AMD 5900HX CPU. I have set up a Jellyfin LXC container and added the following lines to the container's configuration file at `/etc/pve/nodes/<host>/lxc/<id>.conf`:

lxc.cgroup2.devices.allow: c 226:* rwm
lxc.mount.entry: /dev/dri/card0 dev/dri/card0 none bind,optional,create=file
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

I'm able to do VAAPI hardware accelerated decoding/encoding in the container, but I'm unable to access the OpenCL device for tone mapping in Jellyfin.

When I run `clinfo` on the host, I can see the OpenCL device listed. Here's the output:

Number  of platforms:                             1
  Platform Profile:                              FULL_PROFILE
  Platform Version:                              OpenCL 2.1 AMD-APP (3513.0)
  Platform Name:                                 AMD Accelerated Parallel Processing
  Platform Vendor:                               Advanced Micro Devices, Inc.
  Platform Extensions:                           cl_khr_icd cl_amd_event_callback


  Platform Name:                                 AMD Accelerated Parallel Processing
Number of devices:                               1
  Device Type:                                   CL_DEVICE_TYPE_GPU

...

However, when I run `clinfo` in the Jellyfin container, I get the following output:

Number of platforms:                             1
  Platform Profile:                              FULL_PROFILE
  Platform Version:                              OpenCL 2.1 AMD-APP (3513.0)
  Platform Name:                                 AMD Accelerated Parallel Processing
  Platform Vendor:                               Advanced Micro Devices, Inc.
  Platform Extensions:                           cl_khr_icd cl_amd_event_callback


  Platform Name:                                 AMD Accelerated Parallel Processing
Number of devices:                               0

I'm not sure why the OpenCL device is not being detected in the Jellyfin container. Can anyone help me troubleshoot this issue? I've already tried adding the necessary device entries to the container's configuration file, but that didn't seem to help. Any suggestions would be greatly appreciated.

Thanks in advance!

I`m add to `/etc/pve/nodes/<host>/lxc/<id>.conf`:
lxc.mount.entry: /dev/kfd dev/kfd none bind,optional,create=file
lxc.cgroup.devices.allow: c 235:* rwm
And all work.

Can you check if rocminfo works? Doesn't work for me...

root@ollama:~# rocminfo
ROCk module is loaded
Unable to open /dev/kfd read-write: Operation not permitted

Sorry, fixed it myself.
lxc.cgroup.devices.allow: a needed to be lxc.cgroup2.devices.allow: a

@randomuser1990 Did you ever solve this? I'm having the same issue with opencl in lxc with an AMD igpu​
