[Intel-gfx] [PATCH 24/62] drm/i915/bdw: Initialize the PDEs

2013-11-02 Thread Ben Widawsky
The upcoming clear and insert routines will expect that PDEs all point to valid Page Directories. Doing that lazily doesn't really buy us anything. The page allocation is done regardless earlier in init so it shouldn't hurt set the PDEs. v2: Squash in patches to implement fixed PDE write function
