[Mesa-dev] [PATCH 00/11] intel/isl: Add support for HiZ and stencil on gen6

[Jason Ekstrand]

This little series adds support to ISL for gen6 HiZ ans stencil via a new
isl_dim_layout enum value.  Unfortunately, I couldn't easily add the new
layout without doing a little refactoring.  The way ISL likes to calculate
surface layouts today is fairly heavily based on the needs of 2D array
textures.  The gen4 3D and gen9 1D layouts are bolted on but not really
first-class citizens in some sense.  In order to better accommodate more
exotic layouts, I re factored things so that the primary layout helper
generates the total surface extent in elements instead of the slice0 extent
that they were generating before.  I think the new code is somewhat easier
to follow especially for 1D and 3D images.

The last patch moves some things around so that BLORP now handles gen6 HiZ
and stencil properly in the back-end and there is no longer any need for
brw_blorp to do surface offsetting.  I'm hoping that this will make Topi's
life much easier as he tries to rework his "convert i965 to ISL" patches to
accommodate the recent revelation about gen6 HiZ and stencil.
