One valuable information here would be which stack did you use, panfrost and mesa or the ARM stack? If so, with which driver and which blob?

I'm using similar binding (different clock and interrupt names, but otherwise same) for quiet some time now on LibreELEC with ARM proprietary userspace and kernel space driver (32-bit GBM version) and it works well. It's true that I'm using OPP table, but most (if not all) of the time GPU is set to lowest setting as there is not much to do when rendering GUI. Best regards, Jernej

He uses the ARM stack r22p0-01rel0 + patches https://github.com/LibreELEC/LibreELEC.tv/commit/5273f889964c42e88fe02289290c3c6cb6086770 Blob are also from Jernej too (taken from ???) : https://github.com/jernejsk/H6-mali-userspace Regards, Clement > > I'm using similar binding (different clock and interrupt names, but otherwise > same) for quiet some time now on LibreELEC with ARM proprietary userspace and > kernel space driver (32-bit GBM version) and it works well. > > It's true that I'm using OPP table, but most (if not all) of the time GPU is > set to lowest setting as there is not much to do when rendering GUI. > > Best regards, > Jernej > >
