This patch does two things: 1. Constant buffer state changes were broken (but happened to work by dumb luck). The problem is we weren't calling draw_do_flush() in draw_set_mapped_constant_buffer() when we changed that state. All the other draw_set_foo() functions were calling draw_do_flush() already. 2. Use a simpler state validation step when we're changing light-weight parameter state such as constant buffers, viewport dims or clip planes. There's no need to revalidate the whole pipeline when changing state like that. The new validation method is called bind_parameters() and is called instead of the prepare() method. A new DRAW_FLUSH_PARAMETER_CHANGE flag is used to signal these light-weight state changes. This results in a modest but measurable increase in FPS for many Mesa demos.

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.
