From 7eaef1163b820caf202bbb0b1e823806ab836a38 Mon Sep 17 00:00:00 2001 From: Aurabindo Pillai Date: Thu, 5 Jan 2023 14:21:45 -0500 Subject: [PATCH] drm/amd/display: set allow_freesync parameter in DM [Why&how] There are cases where VRR is possible but not enabled. If allow_freesync parameter is not set, SubVP logic defaults to checking only the ignore MSA parameter that is always set if display is DRR capable, which breaks the system while trying to enable SubVP on multi monitor configs where freesync does not work due to Xorg limitation. SubVP uses allow_freesync parameter to check if SubVP + DRR case can be executed.
