[Intel-gfx] [PATCH 20/20] drm/i915/gtt: One instance of scratch page table/directory

2015-05-21 Thread Mika Kuoppala
As we use one scratch page for all ppgtt instances, we can use one scratch page table and scratch directory across all ppgtt instances, saving 2 pages + structs per ppgtt. Signed-off-by: Mika Kuoppala --- drivers/gpu/drm/i915/i915_gem_gtt.c | 288 +++- 1 file chan
