Bug Report: Problems with Mali drivers – versions mismatch?

[tommiv]

What happened?

Trying to make Jellyfin to work with hardware transcoding acceleration, but I have problems with binaries versions mismatch:

dmesg | grep mali | grep DDK
[   47.314926] mali fb000000.gpu: Kernel DDK version g18p0-01eac0

note g18p0 here.

Jellyfin manual asks to install this .deb in particular, "For the 6.1 LTS kernel on Ubuntu-Rockchip".
It doesn't work, and I assume it's because of g13p0 version it's built against.

In this issue there is an advice to just install ibmali-g610-x11 with apt. Sounds cool but doesn't work either.

In both cases, when I run clinfo --list I get some errors about missing kernel mod:

clinfo --list
arm_release_ver: g13p0-01eac0, rk_so_ver: 3
Failed creating base context during opening of kernel driver.
Kernel module may not have been loaded
Platform #0: ARM Platform
arm_release_ver: g13p0-01eac0, rk_so_ver: 3
Failed creating base context during opening of kernel driver.
Kernel module may not have been loaded
 `-- Device #0: <printDeviceInfo:0: get CL_DEVICE_NAME size : error -6>

and there are two lines suggesting g13p0.

I'm not so competent in this, but my assumption is to make it work properly, I need both firmware's DDK and libmali DDK to be the same – g13p0, or g18p0. Unfortunately, I can't find a libmali binary for g18p0 anywhere, and I have no idea how to downgrade the blob to g13p0 safely.

Are there any suggestions?

Kernel version

6.1.0-1025-rockchip
