STATE_BASE_ADDRESS specifies a maximum size of the dynamic state section, beyond which data supposedly reads back as 0. On Gen8+, we were programming it to the size of the buffer. This worked fine until we started growing the state buffer in commit2dfc119f22. When the state buffer grows, the value in STATE_BASE_ADDRESS becomes too small, and our state beyond STATE_SZ bytes would read back as 0. To avoid having to update the value, we program it to MAX_STATE_SIZE. We used to program the upper bound to the maximum on older hardware anyway, so programming it too large isn't a big deal. Bogus SURFACE_STATE can easily lead to GPU hangs and misrendering. DiRT Rally was hitting the statebuffer growth path, and suffered from bad texture corruption and GPU hangs (usually around the same time). This patch fixes both issues. Fixes:2dfc119f22"i965: Grow the batch/state buffers if we need space and can't flush."

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.
