[Intel-gfx] [PATCH] [v3] drm/i915: Fix context sizes on HSW

2013-06-25 Thread Ben Widawsky
With updates to the spec, we can actually see the context layout, and how many dwords are allocated. That table suggests we need 70720 bytes per HW context. Rounded up, this is 18 pages. Looking at what lives after the current 4 pages we use, I can't see too much important (mostly it's d3d related)
