The usage should be client first call AddrComputeSurfaceInfo() on depth surface with flag "matchStencilTilecfg", AddrLib will use 2DThin1 tile index for depth as much as possible and do not down grade unless alignment requirement cannot be met. 1. If there is a matched 2DThin1 tile index for stencil which make sure they will share same tile config parameters, then return the stencil 2DThin1 tile index as well. 2. If using 2DThin1 tile mode cannot make sure such thing happen, and TcCompatible flag was set, then ignore this flag then try 2DThin1 tile mode for depth and stencil again. 3. If 2DThin1 tile mode cannot make sure depth and stencil to have same tile config parameters, then down grade depth surface tile mode to 1DThin1. 4. If depth surface's tile mode was 1DThin1, then return 1DThin1 tile index for stencil. 5. If depth surface's tile mode is PRT, then return invalid tile index to stencil since their tile config parameters will never be met. Client driver then check the returned tile index of stencil -- if it is not invalid tile index, then call AddrComputeSurfaceInfo() on stencil surface with the returned stencil tile index to get full output information. Please note, client needs to set flag "useTileIndex" when AddrLib get created. |

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.
