Hardware contexts are necessary to reasonably support OpenGL 3.2. In particular, we currently maintain software counters for transform feedback buffer offsets and counters, which relies on knowing the number of primitives generated. Geometry shaders violate that assumption. At the time of writing, Debian has moved to Kernel 3.8, which means most people probably have a newer kernel by now. It's also worth noting that this patch won't land until Mesa 10 which is currently targeted for September. By that point, even more people will have a newer kernel. Also, don't bother trying to allocate contexts on pre-Gen6, as it currently will always fail, and if this changes in the future, we'll need to reevaluate our hw_ctx/gen checks. This patch leaves the code for flagging BRW_NEW_CONTEXT on new batchbuffers if hw_ctx == NULL since that still occurs pre-Gen6. Also remove the Gen7+ check for kernel 3.3, since it's now redundant.

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.
