power-profiles-daemon, the power mode settings backend in Gnome, released 0.20 today!
The new release added amdgpu panel power savings which uses dedicated hardware in systems with integrated Radeon graphics to decrease panel power consumption when the system is on battery.
This activates the DRM connector attribute panel_power_savings which takes a range from 0 to 4 to indicate how aggressively to enable panel power savings.

The release also supported multiple power-profiles-daemon drivers to load simultaneously. Which, notably allows both CPU based control with amd-pstate or intel-pstate as well as ACPI platform profile based control.
Due to switch project to the freedesktop ‘Upower’ group. The service now is advertised as org.freedesktop.UPower.PowerProfiles instead of the previous net.hadess.PowerProfiles.
