For gen >= 7, we will use the lod/minimum-array-element fields to support layered rendering. This means that we must restrict the depth & stencil attachments to match in various more retrictive ways. (Now the width, height, depth, LOD and layer must match) The reason width, height, and depth must match is that the hardware has a single set of width, height, and depth settings (in 3DSTATE_DEPTH_BUFFER) that affect both the depth and stencil buffers. Since these controls determine the miptree layout, they need to be set correctly in order for lod and minimum-array-element to work properly. So the only way rendering can work is if the width, height, and depth match. In the future, if this restriction proves to be a problem (say because some crucial client application relies on rendering to different levels/layers of stencil and depth buffers), then we can always work around the restriction by copying depth and/or stencil data to a temporary buffer prior to rendering (much in the same way that brw_workaround_depthstencil_alignment() does today for gen < 7), but hopefully that won't be necessary.

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 osmesa mesagdi to build classic mesa Windows GDI drivers; or 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. 1) install python 2.7 2) install scons (latest) 3) install mingw, flex, and bison 4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get libxml2-python-2.9.1.win-amd64-py2.7.exe 5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe 6) install git 7) download mesa from git see http://www.mesa3d.org/repository.html 8) 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.
