[Intel-gfx] [PATCH] drm/i915: Use 128k alignment for untiled display surface on i965

2010-07-05 Thread Chris Wilson
The original i965 requires an alignment of 128K for the display surface with linear memory, so increase the requirement from 64k for these chipsets. For the later chipsets in the i965 family, only a 4k alignment is required. (So long as we do not start performing asynchronous flips.) Note the
