Subject: [PATCH] drm/amd/powerplay: retrieve VCN dpm table per instances
Date: Tue, 21 Jul 2020 17:01:09 +0800	[thread overview]
Message-ID: <20200721090109.2733-1-Jiansong.Chen@amd.com> (raw)

To accommodate VCN instances variance, otherwise it may trigger
smu response error for configuration with less instances.
