From: Ken Wang Date: Wed, 3 Jun 2015 09:47:54 +0000 (+0800) Subject: drm/amdgpu add ce_ram_size for interface query X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a101a8995ab8072125d0bb4d95425c9fb37ff809;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/amdgpu add ce_ram_size for interface query Add a query for the CE ram size. User mode drivers will want to use this to determine how much size of the cache on the CE.
