This work was initially trigged by the fact that imported surfaces may be backed by other SVGA3D formats than the default. Therefore some fixes were needed to avoid using the copy_region_vgpu10() functionality for incompatible SVGA3D formats where the pipe formats were OK. This situation happens when using dri3. Also in some situations, for example where a R8G8_UNORM surface is backed by an SVGA3D_NV12 format, we can't use the copy_region functionality at all and thus need to fall back to the quad blitter also for the resource_copy_region function. This situation doesn't happen currently, but will if we start using video textures. The patch makes the blit- and copy_region paths similar and the decision whether to use a certain gpu command should now be easy to locate. Probably the resource_copy_region path will suffer from a minor additional cpu overhead, but on the other hand there are more cases now that we accelerate, since we try harder before falling back to cpu copies / blits. v2: Addressed review comments and fixed up piglit failures by sometimes preferring cpu_copy_region() over blit(). v3: Removed a stray test statement.

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.
