This patch rearranges the order of steps performed by a blorp blit from this: - Sync up state of window system buffers. - Find buffers. - Find miptrees. - Make sure buffer formats match. - Handle mirroring. - Make sure width and height match. - Handle clipping/scissoring. - Account for window system origin conventions. - Do depth resolves, if applicable. - Do the blit. - Record the need for a future HiZ resolve, if applicable. To this: - Sync up state of window system buffers. - Handle mirroring. - Make sure width and height match. - Handle clipping/scissoring. - Account for window system origin conventions. - Find buffers. - Make sure buffer formats match. - Find miptrees. - Do depth resolves, if applicable. - Do the blit. - Record the need for a future HiZ resolve, if applicable. The steps are the same, but they are now performed in an order that will make it possible to implement correct DrawBuffers support. Note that the last four steps are now in a separate function (do_blorp_blit), since they will need to be executed repeatedly when DrawBuffers support is added.

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.
