st32mp257f: scarthgap gpu etnaviv optee clk_stm32_pll_init

[Anton Olofsson]

Regarding OpenStLinux (yocto) for stm32mp257f.

 

Mickledore: everything works fine for our custom stm32mp257f board.

 

Scarthgap: everything works except 3D graphics. When loading module etnaviv we get the following system hangup (optee panic):

 

 

[ 13.139084] etnaviv etnaviv: bound 48280000.gpu (ops gpu_ops [etnaviv])
[ 13.186566] videodev: Linux video capture interface: v2.00

We understand it can be hard to say "this is your problem", but any information on where to look would be much appreciated!

 

Best regards,

Anton

For future reference:

It got suggested to us by ST that the problem is that etnaviv is the wrong driver and we should use gcnano driver.
