Subject: [PATCH 1/2] drm/amd/display: Disable dmcu fw loading for dcn314
Date: Tue, 19 Jul 2022 14:26:45 -0400 [thread overview]
Message-ID: <20220719182646.23049-1-Roman.Li@amd.com> (raw)
From: Roman Li <roman.li@amd.com>
[Why]
DCN 3.1.4 uses dmub not dmcu. Attempt to identify
dmcu firmware for dcn314 results in dm init error:
"Unsupported ASIC type"
[How]
Add dcn314 to the list of asics that don't require dmcu
