Here is my two cents. Everythings works. Mali - vpu - open gl(es) - sound - lan. Mini m8s s905. arm-mali-tests are running on fbdev.
For hardware video decoding - https://github.com/OtherCrashOverride/c2play/tree/dualstream, no need for Kodi. It allso can be used with smtube.
One thing - kodi fbdev is needed. If anyone needs i can provide - kernel, modules, mali binary blobs.
