As a quick hack we make the old intel_gtt structure mutable so we can fool a bunch of the existing code which depends on elements in that data structure. We can/should try to remove this in a subsequent patch. This should preserve the old gtt init behavior which upon writing these patches seems incorrect. The next patch will fix these things. The one exception is VLV which doesn't have the preserved flush control write behavior. Since we want to do that for all GEN6+ stuff, we'll handle that in a later patch. Mainstream VLV support doesn't actually exist yet anyway. v2: Update the comment to remove the "voodoo" Check that the last pte written matches what we readback v3: actually kill cache_level_to_agp_type since most of the flags will disappear in an upcoming patch v4: v3 was actually not what we wanted (Daniel) Make the ggtt bind assertions better and stricter (Chris) Fix some uncaught errors at gtt init (Chris) Some other random stuff that Chris wanted v5: check for i==0 in gen6_ggtt_bind_object to shut up gcc (Ben) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by [v4]: Chris Wilson <chris@chris-wilson.co.uk> [danvet: Make the cache_level -> agp_flags conversion for pre-gen6 a tad more robust by mapping everything != CACHE_NONE to the cached agp flag - we have a 1:1 uncached mapping, but different modes of cacheable (at least on later generations).
