Ben Widawsky c4aa041a61 i965/gen8: Correct HALIGN for AUX surfaces 
This restriction was attempted in this commit:
commit 4705346463
Author: Anuj Phogat <anuj.phogat@gmail.com>
Date:   Fri Feb 13 11:21:21 2015 -0800

   i965/gen8: Use HALIGN_16 if MCS is enabled for non-MSRT

However, the commit itself doesn't achieve the desired goal as determined by the
asserts which the next patch adds. mcs_mt is NULL (never set) we're in the
process of allocating the mcs_mt miptree when we get to this function. I didn't
check, but perhaps this would work with blorp, however, meta clears allocate the
miptree structure (which AFAICT needs the alignment also) way before it
allocates using meta clears where the renderbuffer is allocated way before the
aux buffer.

The restriction is referenced in a few places, but the most concise one [IMO]
from the spec is for Gen9. Gen8 loosens the restriction in that it only requires
this for non-msrt surface.

   When Auxiliary Surface Mode is set to AUX_CCS_D or AUX_CCS_E, HALIGN 16 must
   be used.

With the code before the miptree layout flag rework (patches preceding this),
accomplishing this workaround is very difficult.

v2:
bugfix: Don't set HALIGN16 for gens before 8 (Chad)

v3:
non-trivial rebase

File: docs/README.WIN32

Last updated: 21 June 2013


Quick Start
----- -----

Windows drivers are build with SCons.  Makefiles or Visual Studio projects are
no longer shipped or supported.

Run

  scons libgl-gdi

to build gallium based GDI driver.

This will work both with MSVS or Mingw.


Windows Drivers
------- -------

At this time, only the gallium GDI driver is known to work.

Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.

Recipe
------

Building on windows requires several open-source packages. These are
steps that work as of this writing.

- install python 2.7
- install scons (latest)
- install mingw, flex, and bison
- install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
- install git
- download mesa from git
  see http://www.mesa3d.org/repository.html
- run scons

General
-------

After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
in a system directory, place them in the same directory as the
executable(s).  Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.

The DLL files are built so that the external entry points use the
stdcall calling convention.

Static LIB files are not built.  The LIB files that are built with are
the linker import files associated with the DLL files.

The si-glu sources are used to build the GLU libs.  This was done
mainly to get the better tessellator code.

If you have a Windows-related build problem or question, please post
to the mesa-dev or mesa-users list.
