Roland Scheidegger 75f1fea14f llvmpipe: increase fs shader variant instruction cache limit by factor 4
The previous limit of of 128*1024 was reported to cause frequent recompiles
in some apps due to shader variant thrashing on IRC in some apps leading
to noticeable lags.
Note that the LP_MAX_SHADER_VARIANTS limit (1024) was more or less impossible
to reach, since even simple fragment shaders without texturing (glxgears) used
more than twice than 128 instructions, hence the instruction limit would have
always been reached first (excluding things like trivial shaders not writing
color). Even with the new limit it is VERY likely the instruction limit is hit
first.
Should help with such lags due to recompiles (though other shader types have
their own limits, LP_MAX_SETUP_VARIANTS and DRAW_MAX_SHADER_VARIANTS, in
particular the latter seems a bit small (128)).

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.

1) install python 2.7
2) install scons (latest)
3) install mingw, flex, and bison
4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get libxml2-python-2.9.1.win-amd64-py2.7.exe
5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
6) install git
7) download mesa from git
  see http://www.mesa3d.org/repository.html
8) 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.
