[UHD Graphics 605]Tone Mapping with opencl inside a proxmox lxc crashes transcoding.

@ben94  Did you install the ROCM openCL packages on the host?

on both the host and guest i have these packages

Code:

ii  rocm-core                            6.1.0.60100-82~20.04                amd64        Radeon Open Compute (ROCm) Runtime software stack
ii  rocm-language-runtime                6.1.0.60100-82~20.04                amd64        Radeon Open Compute (ROCm) Runtime software stack
ii  rocm-opencl                          2.0.0.60100-82~20.04                amd64        clr built using CMake
ii  rocm-opencl-icd-loader              1.2.60100-82~20.04                  amd64        OpenCL-ICD-Loader built using CMake
ii  rocm-opencl-runtime                  6.1.0.60100-82~20.04                amd64        Radeon Open Compute (ROCm) Runtime software stack

 one thing I noticed, not sure if it matters, is that proxmox seems to keep changing the group of /dev/dri/renderD128 to _chrony

Code:

total 0
drwxr-xr-x 2 root root          80 Apr 23 18:07 by-path
crw-rw---- 1 root video  226,  0 Apr 23 18:07 card0
crw-rw---- 1 root _chrony 226, 128 Apr 23 18:07 renderD128

it seems to be doing this within the same reboot of changing it to render
