From 41b947b00a8b8ea722faeeb79556d75402aa93e6 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 18 Aug 2017 23:52:37 -0400 Subject: [PATCH 0017/4131] drm/amdgpu/gfx9: adjust mqd allocation size To allocate additional space for the dynamic cu masks. Confirmed with the hw team that we only need 1 dword for the mask. The mask is the same for each SE so you only need 1 dword.
