Patch 01: dri2proto
Patch 02: xf86-video-intel
Patch 03-10: mesa
I'm aware that this patch series is painful to review. Thank you in advance
for your reviewed-by's.
There is a related patch series on the intel-gfx list that adds the necessary
functionality to xf86-video-intel. See the thread with subject:
ddx/dri: Add support for hiz and separate stencil buffers
Give close attention to the comments in "intel: Define enum intel_dri2_has_hiz".
That gives an overview of how the DRI2 handshake works and why it is
necessary.
I hear the grumbling already... "Chad significantly altered ancient, core
driver routines! Did he break the world?" I can confidently say "No"; this
patch series causes no regressions.
I have performed full piglit runs that cover all (meaningful)
combinations of the following:
* xf86-video-intel: master vs my hiz branch
* mesa: master vs my hiz branch
* hiz enabled and disabled via environment var overrides
You can find the test results here:

The column's titles should clearly mark what's what; the title format is
"uuid--hostname--mesa@version--xf86-video-intel@version--hiz-[on|off]"
Column 1 is the baseline (mesa@master, ddx@master). Columns 2 and 5 use my
mesa hiz branch with hiz and separate stencil disabled.
The diff from column 1 to 2 shows no regressions and one fix.
