The shader that is used to copy vertex data out of the vs/gs shaders to the user-specified buffer (streamout or SO shader) was not using the correct offsets. Adjust the offsets that are used just for the SO shader: - Make sure that position is handled in the same special way as in the vs/gs shaders - Use the correct offset to be passed in the core - consolidate register slot mapping logic into one function, since it's been calculated in 2 different places (one for calcuating the slot mask, and one for the register offsets themselves Also make room for all attibutes in the backend vertex area. Fixes: - all vtk GL2PS tests - 18 piglit tests (16 ext_transform_feedback tests, arb-quads-follow-provoking-vertex and primitive-type gl_points v2: - take care of more SGV slots in slot mapping logic - trim feState.vsVertexSize - fix GS interface and incorporate GS while calculating vsVertexSize Note that vsVertexSize is used in the core as the one parameter that controls vertex size between all stages, so it has to be adjusted appropriately for the whole vs/gs/fs pipeline. Also note that GS and SO is not fully implemented. This will be addressed later. fixes: - fixes total of 20 piglit tests CC: 17.2 <mesa-stable@lists.freedesktop.org> Reviewed-by: Bruce Cherniak <bruce.cherniak@intel.com>
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.
