[Mesa-dev] [PATCH 00/12] intel: A collection pre-hiz patches

[Chad Versace]

This series lives on my 'hiz-pre' branch.

I have a large hiz series brewing for Haswell.  To make review easier,
I decided to post some preliminary patches first rather than posting the hiz
patch bomb all at once.  If you'd prefer that I shelve this series until I'm
ready to submit the hiz series in its entirety, just let me know.

FYI, hiz hasn't been enabled on Haswell yet because some clumsiness in our
driver hangs the GPU.

Essentially, this patch series does two things:
  patches 1-7:  Lays the groundwork so that we can selectively disable hiz for
  individual miptree images that hang the gpu.

  patches 8-12: In preparation for emitting 8x4 aligned rectangle primitives, 
  add extra padding to hiz and depth miptrees.

Refactors are sprinkled into this series.  In some places, I found it
necessary to clean up the code before I could sufficiently understand it
to confidently make changes.

No regressions against mesa-master-809fdc211, piglit-99055b7, Ivybridge
0x0126.
