Subject: drm/i915: Add information on pinning and fencing to the i915 list debug.
X-Git-Tag: accepted/tizen/common/20141203.182822~17056^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f4ceda89895b56e2c03dd327f13d0256838a20ab;p=platform%2Fkernel%2Flinux-arm64.git

drm/i915: Add information on pinning and fencing to the i915 list debug.

This was inspired by a patch by Chris Wilson, though none of it applied in any
way due to the debugfs work and I decided to change the formatting of the
new information anyway.
