From the Sky Lake PRM: "For SURFTYPE_CUBE: For Sampling Engine Surfaces and Typed Data Port Surfaces, the range of this field is [0,340], indicating the number of cube array elements (equal to the number of underlying 2D array elements divided by 6). For other surfaces, this field must be zero." In other words, the depth field for cube maps is in number of cubes not number of 2-D slices so we need to divide by 6. ISL will do this correctly for us assuming that we provide it with the correct array bounds which it expects to be in 2-D slices. It appears as if we've been doing this wrong ever since we first added cube map arrays for Sandy Bridge and the change to ISL made things slightly worse. While we're at it, we now need to remoe the shader hacks we've always done since they were only needed because we were setting the depth field six times too large. v2: Fix the vec4 backend as well (not sure how I missed this).

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.
