With this patch, a guest-backed surface will be invalidated
using the SVGA_3D_CMD_INVALIDATE_GB_SURFACE command before
the surface is reused. This fixes the updating dirty image error
from the device when a surface is reused.
v2: Instead of invalidating the surface when it is reused,
send the invalidate command before the surface is put into
the recycle pool.
v3: (1) surface invalidate is a noop operation in Linux winsys, since
surface invalidation is not needed for DMA path.
(2) Instead of invalidating the surface content in
svga_screen_surface_destroy() when a surface is to be destroyed,
it is done in svga_screen_cache_flush() when the surface is
no longer referenced in a command buffer and is ready to
be moved to the unused list. At this point, the surface will
be moved to the invalidate list. When the surface invalidation
is submitted, the surface will be moved to the unused list.
Tested with piglit, glretrace.

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.
