The GS has an interesting use for mul. Because the GS can emit multiple vertices per input vertex, and it also has a unique count at the top of the URB payload, the GS unit needs to be able to dynamically specify URB write offsets (relative to the global offset). The documentation in the function has a very good explanation from Paul on the mechanics. This fixes around 2000 piglit tests on BSW. v2: Reworded commit message (Ben) no mention of CHV (Matt) Change SHRT_MAX to USHRT_MAX (Ken, and Matt) Update comment in code to reflect the use of UW (Ben) Add Gen7+ assertion for the relevant GS code, since it won't work on Gen6- (Ken) Drop the bogus hunk in emit_control_data_bits() (Ken) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=84777 (with many dupes) Cc: "10.4 10.3 10.2" <mesa-stable@lists.freedesktop.org> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Matt Turner <mattst88@gmail.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 osmesa mesagdi to build classic mesa Windows GDI drivers; or 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.
