From: Ben Widawsky Date: Mon, 24 Sep 2012 15:55:51 +0000 (-0700) Subject: drm/i915: Add dev to ppgtt X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=8f2c59f0aa3acefbd26443860245c014fa64549b;p=linux-edison.git drm/i915: Add dev to ppgtt Some subsequent commits will need to know what generation we're running on to do different pte encoding for the ppgtt. Since it's not much hassle or overhead to store it in the ppgtt structure, do that.
