From: Christian König Date: Tue, 12 Apr 2016 14:26:34 +0000 (+0200) Subject: drm/amdgpu: use max_dw in ring_init X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a3f1cf355e90e144f012cbb0472a6701dd832841;p=linux-beck.git drm/amdgpu: use max_dw in ring_init Instead of specifying the total ring size calculate that from the maximum number of dw a submission can have and the number of concurrent submissions. This fixes UVD with 8 concurrent submissions or more.
