[PATCH v2 0/4] Add support for testing power saving policy 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 or low latency is preferred over power savings.

To accomplish this a new optional DRM property is being introduced called
"power saving policy".  This property is a bit mask that can be configured
by the compositor to for it's requirements.

When a driver advertises support for this property and the compositor
sets requirements then the driver will disable any appplicable power saving
features that can compromise the requirements.

This set of IGT changes introduces a new subtest that will cover the
expected kernel behavior when switching between requirements.

Mario Limonciello (4):
  Add support for API for drivers to set power saving policy
  tests/amdgpu/amd_abm: Make set_abm_level return type int
  tests/amdgpu/amd_abm: Add support for panel_power_saving property
  tests/amdgpu/amd_psr: Add support for `power saving policy` property
