Panfrost power transition timeout errors

[dreamlayers]

I have an x92 box with Amlogic Meson GXM (S912). The SOC has a Mali-T820 GPU, and the box has 2 GB of RAM and 16 GB of eMMC. I'm running Armbian 25.11.2 noble on it. While using the Wayfire Wayland GUI, there is a lot of kernel output like this, constantly repeating:

 

panfrost d00c0000.gpu: shader power transition timeout
panfrost d00c0000.gpu: tiler power transition timeout
panfrost d00c0000.gpu: l2 power transition timeout

 

The GUI works, and hardware 3D acceleration works. But it would be nice to get this spam out of the logs, and I also wonder if there is really some problem. Like, maybe the kernel doesn't know how to change GPU voltages. Maybe it is related to this at boot, maybe due to an issue with the device tree. 

 

kernel: panfrost d00c0000.gpu: error -ENODEV: _opp_set_regulators: no regulator (mali) found

 

The only other sign of something being possibly wrong is that SOC temperature goes surprisingly high when playing hardware accelerated video. That ought to be energy efficient. I'm running Mopidy and Firefox at 53°C and just playing a video can get it to 70°C.

There is no gpu support in these amlogic tvbox builds.

What does that mean? Panfrost is the GPU driver, for the Mali-T820 GPU. I have hardware acceleration for 3D graphics and video playback, in Armbian.
