From 3be6a63e06573d4e55fabda8873b73327cf73da8 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Fri, 23 Feb 2024 10:46:34 -0500 Subject: [PATCH] drm/amd/display: Enable reallow for idle on DCN35 [Why] It was previously disabled for stability purposes, but command submission causes residency issues in IPS video playback. [How] Enable the disallow/reallow pattern back. There's additional checks now in DMCUB that should make this safer stability wise.
