2014-09-19drm/i915: split intel_cursor_plane_update() into check() and commit()Gustavo Padovan
Due to the upcoming atomic modesetting feature we need to separate some update functions into a check step that can fail and a commit step that should, ideally, never fail. The commit part can still fail, but that should be solved in another upcoming patch.

2014-09-19drm/i915: Match GTT space sanity checker with implementationChris Wilson
If we believe that the device can cross cache domains in its prefetcher (i.e. we allow neighbouring pages in different domains), we don't supply a color_adjust callback. Use the presence of this callback to better determine when we should be verifying that the GTT space we just used is valid. v2: Remove the superfluous struct drm_device function param as well.

2014-09-19drm/i915: HSW always use GGTT selector for secure batchesChris Wilson
gen6 and earlier conflate address space selection (ppgtt vs ggtt) with the security bit (i.e. only privileged batches were allowed to run from ggtt). From Haswell only, you are able to select the security bit separate from the address space - and we always requested to use ppgtt. This breaks the golden render state batch execution with full-ppgtt as that is only present in the global GTT and more generally any secure batch that is not colocated in the ppgtt and ggtt. So we need to disable the use of the ppgtt selector bit for secure batches, or else we hang immediately upon boot and thence after every GPU reset... v2: Only HSW differentiates between secure dispatch and ggtt, so simply ignore the differentiation and always use secure==ggtt.

2014-09-19drm/i915: Drop any active reference before unbindingChris Wilson
Before we process the final unbind on an object and move it to the unbound list, it is semantically cleaner if there are no more active references to the object. (An active reference would imply that it was still being accessed by the GPU after it became inaccessible.) The caveat is that all callsites must be prepared for the object to disappeared during the unbind - i.e. they must hold their own reference.

2014-09-19drm/i915: Limit the watermark to at least 8 entries on gen2/3Ville Syrjälä
830 is very unhappy of the watermark value is too low (indicating a very high watermark in fact, ie. memory fetch will occur with an almost full FIFO). Limit the watermark value to at least 8 cache lines. That also matches the burst size we use on most platforms. BSpec seems to indicate we should limit the watermark to 'burst size + 1'. But on gen4 we already use a hardcoded 8 as the watermark value (as the spec says we should), so just use 8 as the limit on gen2/3 as well.
