For 32-bit instructions we want to use <4,4,1> regions for VGRF sources so we should really set a width of 4 (we were setting 8). For 64-bit instructions we want to use a width of 2 because the hardware uses 32-bit swizzles, meaning that we can only address 2 consecutive 64-bit components in a row. Also, Curro suggested that the hardware is probably fixing the width to 2 for 64-bit instructions anyway, so just go with that and use <2,2,1>. v2: - No need to explicitly set the vertical stride of 64-bit regions to 2, brw_vecn_grf with a width of 2 will do that for us. - No need to adjust the width of dst registers. v3 (Ian): - Make type_size and width const.

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.
