anv_format::surface_format was incorrect for Vulkan depth formats.
For example, the format table mapped
VK_FORMAT_D24_UNORM -> .surface_format = D24_UNORM_X8_UINT
VK_FORMAT_D32_FLOAT -> .surface_format = D32_FLOAT
but should have mapped
VK_FORMAT_D24_UNORM -> .surface_format = R24_UNORM_X8_TYPELESS
VK_FORMAT_D32_FLOAT -> .surface_format = R32_FLOAT
The Crucible test func.depthstencil.basic passed despite the bug, but
only because it did not attempt to texture from the depth surface.
The core problem is that RENDER_SURFACE_STATE.SurfaceFormat and
3DSTATE_DEPTH_BUFFER.SurfaceFormat are distinct types. Considering them
as enum spaces, the two enum spaces have incompatible collisions.
Fix this by adding a new field 'depth_format' to struct anv_format.
Refer to brw_surface_formats.c:translate_tex_format() for precedent.
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.
