RX 5700 XT Navi - amdgpu.ppfeaturemask=0xffffffff causes stuttering and does not unlock clock/voltage/power controls
Submitted by Xul Demonslayer
Assigned to Default DRI bug account
with Polaris and Vega, setting amdgpu.ppfeaturemask=0xffffffff worked without issues here: It unlocked pp_od_clk_voltage and didn't cause any issues for me.
But with Navi, it doesn't work. I'm still not allowed to open
as root with specifying that flag.
Also, I can't increase the GPU's power consumption, as
only allows the default 100% Powertune limit, meaning I can't set any higher value in
Apart from not being able to change the aforementioned parameters, setting amdgpu.ppfeaturemask=0xffffffff causes stuttering, even on the desktop and also affects the mouse cursor.
This is with kernel drm-next-5.5-wip 73cdff347343504287feae8b36fa7317f04dcc61
and an MSI 5700 XT Gaming X.
