[PATCH 0/7] Increase the utilization of Stolen area on VLV

[PATCH 0/7] Increase the utilization of Stolen area on VLV

[akash.goel]

From: Akash Goel <akash.goel@intel.com>

These patches are mainly for increasing the utilization
of stolen memory area on VLV. 
Although the changes were already there to allocate few 
internal resources from stolen area, but due to a resource 
conflict the stolen area was not getting used at all. 
The third patch is also a bug fix but specific only to VLV. 
The rest of the patches actually increase the utilization 
stolen area on VLV by allocating User created frame buffers
(only X tiled).
These changes proved especially useful for Android BYT products,
which had smaller RAM(1GB), where it enabled playback of most 
of the available 3D games/Apps.

Akash Goel (7):
  drm/i915: Fix the offset issue for the stolen GEM objects
  drm/i915: Resolving the memory region conflict for Stolen area
  drm/i915/vlv: Not reallocating VLV PCTX upon every suspend/resume
  drm/i915: Added an identifier for User frame buffers to Gem obj
    structure
  drm/i915/vlv: Increase the utilization of stolen memory on VLV.
  drm/i915/vlv: Clear out contents of Frame buffer allocations from
    Stolen area
  drm/i915/vlv: Use Blitter Engine to clear out contents of Stolen frame
    buffers

Hi Akash, please check your git sendemail.thread configuration (or
format.thread for format-patch) to make the patches in-reply-to the
cover letter.

Thanks,
