The state tracker may generate shaders that use generic vs outputs / fs inputs like: DCL IN[0], GENERIC[0] DCL IN[1], GENERIC[10] DCL IN[2], GENERIC[11] This patch remaps 0, 10, 11 to small integers like 1, 2, 3 so that we stay inside the SVGA3D limit (8). The remapping is done to both the vertex shader outputs and the fragment shader inputs. The same mapping must be used for a vs/fs pair. Note that 'union svga_compile_key' is now 'struct svga_compile_key' because we needed to add the register remapping table. The change in size isn't really significant though (it's not a search key). Also, add assertions when building up SVGA3D src/dst registers to we don't try to store too large of value for the bitfield size. Reviewed-by: José Fonseca <jfonseca@vmware.com>
File: docs/README.WIN32 Last updated: 23 April 2011 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. 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.
