[Intel-gfx] [PATCH 07/66] drm/i915: Use drm_mm for PPGTT PDEs

2013-06-27 Thread Ben Widawsky
When PPGTT support was originally enabled, it was only designed to support 1 PPGTT. It therefore made sense to simply hide the GGTT space required to enable this from the drm_mm allocator. Since we intend to support full PPGTT, which means more than 1, and they can be created and destroyed ad hoc
