Two bugs in GPU reporting for Raspberry Pi 5

[taprobane99]

Is there an existing issue for this?

• [x] I searched the existing issues and did not find anything similar.

Current Behavior

1. Video Decoder Usage remains at 0% when playing a HVEC video using the onboard HVEC (h.265) hardware decoder.

2. GPU % often above 100%, for example reporting 135% when using the Cavalier visualiser.

Expected Behavior

1. Video decoder showing values above 0% when playing HVEC
2. GPU % never exceeding 100%

Hi, thanks for the issue.

Regarding your first problem, the v3d driver responsible for the GPU of the Raspberry Pi does not support monitoring encoder/decoder usage, which is unfortunately not represented well in the GUI. Regarding your second issue, this shouldn't happen of course, I'm gonna investigate that. :)
