Robin,
Many thx!
Indeed issue was with SCMi CLK.
Now i see:
[ 3.092350] panfrost fde60000.gpu: clock rate = 594000000
[ 3.092906] panfrost fde60000.gpu: bus_clock rate = 500000000
[ 3.138340] panfrost fde60000.gpu: clock rate = 594000000
[ 3.138904] panfrost fde60000.gpu: bus_clock rate = 500000000
[ 3.171244] panfrost fde60000.gpu: clock rate = 594000000
[ 3.171888] panfrost fde60000.gpu: bus_clock rate = 500000000
good.
(unfortunately mesa 21.3.4 still goes with llvmpipe but this seems to be other issue i need to investigate)
thx again!
