OMAP3530: HW Acceleration won't work with SGX (BRANCH 1.17.4948957/mesa/glibc-2.35) and Linux 6.6 under use of yocto

Frank Obergfell

Part Number: OMAP3530

Tool/software:

Haven't found part NO OMAP3630 so I selected 3530.
I have a custom board based on the omap3-beagle-xm.
I try to update it from Kernel 3.X to 6.6.x under use of yocto.
With the latest recipe which uses the latest branch "1.17.4948957/mesa/glibc-2.35"
Didn't get the GPU acceleration to work.
The KM Module is loaded and there is no issue on starting the pvrsrvctl driver.
(After removing the 50-... udev rule. otherwise I get Error 129 already loaded)

[~ ]$ /etc/init.d/rc.pvr start
[ 378.953186] [drm] Initialized pvr 1.17.4948957 20110701 for 50000000.gpu on minor 1
[ 378.995422] PVR_K: UM DDK-(4948957) and KM DDK-(4948957) match. [ OK ]
Loaded PowerVR consumer services.

When starting kmscube it mentions that the display is not initialised and starts turning the cube without acceleration (2.8Fps)

[ ~ ]$ kmscube
MESA: info: Loaded libpvr_dri_support.so
PVR:(Error): PVRDRICreateScreenImpl: Failed to create display device (err=19) [0, ]
MESA: info: Unloaded libpvr_dri_support.so
kmsro: driver missing
Using display 0x5fc2d0 with EGL version 1.4
...

Any Ideas where I could make the issue?
