From 442702b490246df4b926fa36bac09193b231f100 Mon Sep 17 00:00:00 2001 From: Roman Li Date: Thu, 26 Sep 2024 16:36:15 -0400 Subject: [PATCH] drm/amd/display: Align static screen idle worker with IPX mode [Why] Idle worker thread serves for periodic detection of HPD while system is in IPS2. Currently it is used in headless and static screen scenarios. IPX can be configured not to execute IPS2 for static screen. In this case idle worker is redundant. [How] Only use periodic detection for static screen if IPS is fully enabled.
