With the exception of the default tess levels only ever accessed by the default tcs shader, the LDS_INFO const buffer was only accessed by vtx instructions, and not through kcache. No idea why really, but use this to our advantage by not using a constant buffer slot for it. This just requires us to throw the default tess levels into the "normal" driver const buffer instead. Alternatively, could acesss those constants via vtx instructions too, but then we couldn't use a ordinary ureg prog accessing them as constants and would have to generate that directly when compiling the default tcs shader. (Another alternative would be to put all lds info into the ordinary driver const buffer, albeit we'd maybe need to increase the fixed size as it can't fit alongside the ucp since vs needs access to the lds info too.)

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.
