Public bug reported: GPU=Rx vega m gl Release=Focal, 20.04 (development) xserver-xorg-video-amdgpu version=19.1.0-1 (active development)
The expected outcome of altering the file, pp_od_clk_voltage, p-states cannot be changed using echo commands i.e. echo "s 3 700 700" > /sys/class/drm/card1/device/pp_od_clk_voltage Various variations of the above have been tried, including using sudo su and checking file write permissions. The file power_dpm_force_performance_level could be changed only within sudo su when DRI_PRIME=1 was used to open a program in the background i.e. DRI_PRIME=1 steam: sudo su echo "manual" > /sys/class/drm/card1/device/power_dpm_force_performance_level Following this, pp_od_clk_voltage could still not be changed. A similar bug was found here; https://gitlab.freedesktop.org/drm/amd/issues/574 However, I was not able to amend any P-states as described in the bug described in this link. The voltages and clock speeds cannot be amended. ** Affects: xserver-xorg-video-amdgpu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1861633 Title: Rx vega m gl undervolt and overclock pp_od_clk_voltage values cannot be changed using echo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1861633/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
