This calculates a rather conservative partitioning of the L3 cache based on the shaders currently bound to the pipeline and whether they use SLM, atomics, images or scratch space. The result is intended to be fine-tuned later on based on other pipeline state. Note that the L3 partitioning calculated for VLV in the non-SLM non-DC case differs from the hardware defaults in that it doesn't include a DC partition and has twice as much RO cache space -- This is an intentional functional change that improves performance in several bandwidth-bound benchmarks on VLV (5% significance): SynMark OglTexFilterAniso by 14.18%, SynMark OglTexFilterTri by 7.15%, Unigine Heaven by 4.91%, SynMark OglShMapPcf by 2.15%, GpuTest Fur by 1.83%, SynMark OglDrvRes by 1.80%, SynMark OglVsTangent by 1.71%, and a few other benchmarks from the Finnish system by less than 1%.

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.
