From 77df677291ae1c155c29ff82be633cdd0df3f5ca Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sat, 2 Nov 2013 21:07:30 -0700 Subject: [PATCH] drm/i915/bdw: ppgtt info in debugfs It's not so much that the information is terribly useful, but rather that the gen6/7 information is completely useless.
