From: Daniel Vetter Date: Wed, 14 Dec 2011 12:57:01 +0000 (+0100) Subject: drm/i915: refactor ring error state capture to use arrays X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d27b1e0ec2a0a04770b2ebf70a2e01281ef93562;p=mv-sheeva.git drm/i915: refactor ring error state capture to use arrays The code already got unwieldy and we want to dump more per-ring registers. Only functional change is that we now also capture the video ring registers on ilk. v2: fixup a refactor fumble spotted by Chris Wilson.
