We now flush the batch when either the batchbuffer or statebuffer reaches the original intended batch size, instead of when the sum of the two reaches a certain size (which makes no sense now that they're separate buffers). With this change, we also need to update our "are we near the end?" estimate to require separate batch and state buffer space. I obtained these estimates by looking at the size of draw calls in the Unreal 4 Elemental Demo (using INTEL_DEBUG=flush and always_flush_batch=true). This will significantly impact the size of our batches. I've adjusted both down to try and be roughly similar to what we had been doing. On various benchmarks, a 20kB batch and 16kB statebuffer seemed to about right, but we may need to adjust this further. I tried a 16kB batch, but that regressed Synmark OglMultithread performance by a fair bit. 32kB for both would have significantly increased our batch sizes.

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.
