James Jones 68d70fb969 gallium: Add format modifier plane count query 
Rather than hard-code a list of all the format
modifiers supported by any gallium driver and the
number of aux planes they require in the dri state
tracker, add a screen proc that queries the number
of planes required for a given modifier+format
pair.

Since the only format modifiers that require
auxiliary planes currently are the iris driver's
I915_FORMAT_MOD_Y_TILED_CCS,
I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS, and
I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS, the absence
of the screen proc implies zero aux planes for all
of the screen's supported modifiers.  Hence, when
a driver does not expose the proc, derive the
number of planes directly from the format.

README.WIN32 

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 https://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.
