Subject: [PATCH 11/31] drm/amd/display: Fix hard hang if DSC is disabled
Date: Fri, 15 Jul 2022 14:16:45 -0400 [thread overview]
Message-ID: <20220715181705.1030401-12-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20220715181705.1030401-1-Rodrigo.Siqueira@amd.com>
We want to calculate the DTB clock values when DSC is enabled; however,
this is not the current behavior implemented in DCN32. Right now, DML is
trying to calculate DSC values even if DSC is disabled; as a result, we
can have a hard hang due to wrong clock calculation. This commit fixes
this issue by moving the calculation after the DSC check.
