Until now we only used MRFs 1..15 for regular SEND messages, so the message length could not possibly exceed the maximum size. Soon we'll allow to use MRF registers 1..23 in gen6, so we need to be careful not to build messages that can go beyond the limit. That could occur, specifically, when building URB write messages, which we may need to split in chunks due to their size. Previously we would simply go and create a new message when we reached MRF 13 (since 13..15 were reserved for spilling), now we also want to check the size of the message explicitly. Besides adding that condition to split URB write messages properly, this patch also adds asserts in the generator. Notice that brw_inst_set_mlen already asserts for this, but asserting in the generators is easy and can make debugging easier in some cases. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
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 http://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.
