In order to implement the GL_PRIMITIVES_GENERATED query in a sane fashion on our hardware, we can't discard primitives until the clipper. The patch after next explains the rationale. By setting the clipper to REJECT_ALL mode, all primitives get thrown away, so rendering is still appropriately disabled. This may negatively impact performance in the rasterizer discard case, but it's unclear how much and this hasn't been observed to be a bottleneck in any application we've looked at. The clipper is the very next stage in the pipeline, so I don't think it will be terrible. v2: Add a perf_debug; resolve rebase conflicts on the brw dirty flags.

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.
