   1 Here is a brief explanation on how to sync Mesa in trunk base.

   3 Current version is 8.0.4

   5 - SOURCE FILES :
   6 ________________
   7
   8 All unnecessary files and directories where removed from the tree, as it's already a huge piece of code.
   9
  10  - build tools (bin, configs, scons, src/gallium/tools) were removed, as we don't use it.
  11  - documentation (docs, src/gallium/docs, doxygen) were removed. If you want to contribute to libMesa, you'd better use their build system, not our adapted one
  12  - tests and testing tools were removed (test, src/gallium/tests, src/gallium/tools)
  13  - egl functionality (src/egl) is useless to us and were removed.
  14  - gbm functionality (src/gbm) is useless to us and were removed.
  15  - getopt implementation (src/getopt, for MSVC compatibility) is useless to us, we already have one
  16  - glx (src/glx) functionality is useless to us and were removed.
  17  - src/gallium
  18    - All gallium drivers (src/gallium/driver) where deleted, except for the softpipe  one.
  19    - All gallium state trackers (src/gallium/state_trackers) were removed, except for the wgl one
  20    - All gallium targets (src/gallium/targets) were removed, except for the libgl-gdi one.
  21    - All gallium window system backends (src/gallium/winsys) were removed, except for the gdi one (sw/gdi)
  22  - src/mapi
  23    - only mapi and glapi directories were relevant and kept
  24  - src/mesa
  25    - All MESA drivers where deleted (src/mesa/drivers), except for the "common" part and osmesa (off-screen mesa) library.
  26    - Architecture specifics were removed. x86 and x86_64 might be restored in future
  27  - src/glu where kept and will be used for the glu32 dll implementation

  30 - GENERATED FILES:
  31 __________________

  33 libMesa build system generates source files (using scons).
  34 They were taken from an out-of-source build an put in the "generated" directory, using the same
  35 directory structure for the sake of ease of maintainability.

  38 - CMAKELISTS FILES:

  41 Those files were written using the Sconscript and source list files as reference. I think that diff-ing them between two
  42 versions would permit to easily update the cmake configuration files.
