[PATCH 0/2] Add support for testing panel power saving DRM property

[Mario Limonciello]

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.
