Kenneth Graunke 5e6ee119c0 i965: Use BDW_MOCS_PTE for renderbuffers.
Write-back caching cannot be used for buffers being scanned out by the
display engine; surfaces used for scan-out must be write-through or
uncached.  I originally chose WT for render targets because it works in
all cases.  However, we really want to use write-back caching where
possible, as it is more efficient.

Most renderbuffers are not used for scanout - off-screen FBOs certainly
are fine, and non-pageflipped backbuffers should be fine as well.  So
in most cases WB will work.  However, we don't know what will be used
for scan-out, so we instead simply use the PTE value specified by the
kernel, as it knows these things.

This matches our MOCS choice on Haswell.

Fixes performance regressions since commit ee4484be3d
in a microbenchmark (spotted by Eero Tamminen).  Improves performance
in GLBenchmark 2.7/EgyptHD by 7.44362% +/- 0.496939% (n=55) on a
Broadwell GT2.  Improves performance in a bunch of other microbenchmarks
by ~15% or so.

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 osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  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.
