[HW Accel Support]: Failed to initialize PMU

[Phyxsius7]

Describe the problem you are having

After having read the following issue #5271.
I would like to know if GPU support is still not support by Frigate addon.
The log message "ERROR : Unable to poll intel GPU stats: Failed to initialize PMU! (Permission denied)" does seem to suggest that it is still not supported but maybe it is supported after additional setting have been set.

[NickM-27]

this is just an issue of getting the GPU stats, it does not mean the GPU itself is not working

[Phyxsius7]

thanks for the prompt reply.
then I would like to know:
how to make sure that GPU is being used or rather not being used?

[NickM-27]

if you have defined hwaccel args and frigate is not showing errors in the logs then it is working.

[Phyxsius7]

what should I look for in the log and do I need to change the logging type for this?

[NickM-27]

It would be errors
