During the Display Next hackfest 2024 one of the topics discussed was the need for compositor to be able to relay intention to drivers that color fidelity is preferred over power savings.
To accomplish this a new optional DRM property is being introduced called "panel power saving". This property is an enum that can be configured by the compositor to "Allowed" or "Forbidden". When a driver advertises support for this property and the compositor sets it to "Forbidden" then the driver will disable any power saving features that can compromise color fidelity. This set of IGT changes introduces a new subtest that will cover the expected kernel behavior when switching between Allowed and Forbidden.
