This moves it to being based on layout_to_aux_usage instead of being hard-coded based on bits of a priori knowledge of how transitions interact with layouts. This conceptually simplifies things because we're now using layout_to_aux_usage and layout_supports_fast_clear to make resolve decisions so changes to those functions will do what one expects. There is a potential bug with window system integration on gen9+ where we wouldn't do a resolve when transitioning to the PRESENT_SRC layout because we just assume that everything that handles CCS_E can handle it all the time. When handing a CCS_E image off to the window system, we may need to do a full resolve if the window system does not support the CCS_E modifier. The only reason why this hasn't been a problem yet is because we don't support modifiers in Vulkan WSI and so we always get X tiling which implies no CCS on gen9+. This patch doesn't actually fix that bug yet but it takes us the first step in that direction by making us actually pick the correct resolve op. In order to handle all of the cases, we need more detailed aux tracking. v2 (Jason Ekstrand): - Make a few more things const - Use the anv_fast_clear_support enum v3 (Jason Ekstrand): - Move an assert and add a better comment Reviewed-by: Topi Pohjolainen <topi.pohjolainen@intel.com> Reviewed-by: Nanley Chery <nanley.g.chery@intel.com>
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.
