From: Ville Syrjälä Date: Wed, 4 Nov 2015 21:20:10 +0000 (+0200) Subject: drm/i915: Give names to more ring registers X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=35dc3f97a69bb344768c6a2f47da2be46b11645a;p=linux-beck.git drm/i915: Give names to more ring registers The logical render context population has a bunch of raw ring register offsets. Use the names we have for them, and in cases where we we don't, give them names.
