From a101a8995ab8072125d0bb4d95425c9fb37ff809 Mon Sep 17 00:00:00 2001
From: Ken Wang <Qingqing.Wang@amd.com>
Date: Wed, 3 Jun 2015 17:47:54 +0800
Subject: [PATCH 0240/1050] 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.
