For 10.6: This fixes graphical corruption occuring on most Southern Islands
Radeon GPUs. This will allow closing a lot of bugs in the bugzilla.
The patch has a better explanation. Just a summary here:
- The CPU always uploads a whole descriptor array to previously-unused memory.
- CP DMA isn't used.
- No caches need to be flushed.
- All descriptors are always up-to-date in memory even after a hang, because
CP DMA doesn't serve as a middle man to update them.
This should bring:
- better hang recovery (descriptors are always up-to-date)
- better GPU performance (no KCACHE and TC flushes)
- worse CPU performance for partial updates (only whole arrays are uploaded)
- less used IB space (no CP_DMA and WRITE_DATA packets)
- simpler code
- corruption issues are fixed on SI cards

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.
