When multiview is active a subpass clear may only clear a subset of the attachment layers. Other subpasses in the same render pass may also clear too and we want to honor those clears as well, however, we need to ensure that we only clear a layer once, on the first subpass that uses a particular layer (view) of a given attachment. This means that when we check if a subpass attachment needs to be cleared we need to check if all the layers used by that subpass (as indicated by its view_mask) have already been cleared in previous subpasses or not, in which case, we must clear any pending layers used by the subpass, and only those pending. v2: - track pending clear views in the attachment state (Jason) - rebased on top of fast-clear rework. v3: - rebased on top of subpass rework. v4: rebased. v5 (Caio): - Rebased. - Initialize pending clear views to only have bits set for layers that exist. - Reset pending clear views in one go rather one bit at a time. - Put "last subpass for this attachment" condition in a separate function to simplify the conditional that resets pending_clear_aspects.

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.
