Chris Wilson 9da3da660d drm/i915: Replace the array of pages with a scatterlist ... Rather than have multiple data structures for describing our page layout in conjunction with the array of pages, we can migrate all users over to a scatterlist. One major advantage, other than unifying the page tracking structures, this offers is that we replace the vmalloc'ed array (which can be up to a megabyte in size) with a chain of individual pages which helps reduce memory pressure. The disadvantage is that we then do not have a simple array to iterate, or to access randomly. The common case for this is in the relocation processing, which will typically fit within a single scatterlist page and so be almost the same cost as the simple array. For iterating over the array, the extra function call could be optimised away, but in reality is an insignificant cost of either binding the pages, or performing the pwrite/pread. v2: Fix drm_clflush_sg() to not invoke wbinvd as well! And fix the trivial compile error from rebasing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2012-09-20 14:22:57 +02:00
