I tested it on RRD board (against next-20261009). While kmscube seems
running fine, I saw the following errors.

root@qcom-armv8a:~# kmscube
[   30.192468] adreno 3d00000.gpu: [drm:adreno_zap_shader_load [msm]] *ERROR* Unable to authorize the image
[   30.192503] msm_dpu ae01000.display-controller: [drm:adreno_load_gpu [msm]] *ERROR* gpu hw init failed: -22
[   30.202644] platform 3d6a000.gmu: [drm:a6xx_gmu_set_oob [msm]] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0

Are they relevant? Or am I missing something?
