Since our surface state buffer is shared by all batches, the kernel does a full stall and sync with the CPU between batches every time we call execbuf2 because it refuses to do relocations on an active buffer. Doing them in userspace and passing the NO_RELOC flag to the kernel allows us to perform the relocations without stalling. This improves the performance of Dota 2 by around 30% on a Sky Lake GT2. v2 (Jason Ekstrand): - Better comments (Chris Wilson) - Fixed write_reloc for correct canonical form (Chris Wilson) v3 (Jason Ekstrand): - Skip relocations which aren't needed - Provide an environment variable to always use the kernel - More comments about correctness (Chris Wilson) v4 (Jason Ekstrand): - More comments (Chris Wilson) v5 (Jason Ekstrand): - Rebase on top of moving execbuf2 setup go QueueSubmit Signed-off-by: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Kristian H.

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.
