From 9d8c094ddab05db88d183ba82e23be807848cad8 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 3 Jul 2024 00:17:22 -0500 Subject: drm/amd: Add power_saving_policy drm property to eDP connectors When the `power_saving_policy` property is set to bit mask "Require color accuracy" ABM should be disabled immediately and any requests by sysfs to update will return an -EBUSY error. When the `power_saving_policy` property is set to bit mask "Require low latency" PSR should be disabled. When the property is restored to an empty bit mask ABM and PSR can be enabled again.
