Subject: [PATCH 02/19] drm/amd/display: Add DSC check to seamless boot validation
Date: Fri, 16 Apr 2021 10:34:00 -0400	[thread overview]
Message-ID: <20210416143417.611019-3-aurabindo.pillai@amd.com> (raw)
In-Reply-To: <20210416143417.611019-1-aurabindo.pillai@amd.com>

From: Anthony Wang <anthony1.wang@amd.com>

[Why & How]
We want to immediately fail seamless boot validation if DSC is active,
as VBIOS currently does not support DSC timings. Add a check for
the relevant flag in dc_validate_seamless_boot_timing.
