Subject: [PATCH 1/2] drm/amdgpu: fix to use real compute unit number for shader array mask
Date: Thu, 23 Sep 2021 13:42:00 +0800 [thread overview]
Message-ID: <20210923054201.1433036-1-ray.huang@amd.com> (raw)
We should use the real compute unit number for shader array mask. Some
asic doesn't have 16 compute units per shader array.
