| Summary | RX 5700 XT Navi - amdgpu.ppfeaturemask=0xffffffff causes stuttering and does not unlock clock/voltage/power controls |
| Product | DRI |

Hello, 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 /sys/class/drm/card0/device/pp_od_clk_voltage as root with specifying that flag. Also, I can't increase the GPU's power consumption, as /sys/class/drm/card0/device/hwmon/hwmon0/power1_cap_max only allows the default 100% Powertune limit, meaning I can't set any higher value in /sys/class/drm/card0/device/hwmon/hwmon0/power1_cap 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.
