Swr caches fb contents in tiles. Those tiles are stored on a per-context basis. When switching contexts that share resources we need to make sure that the tiles of the old context are being stored and the tiles of the new context are being invalidated (marked as invalid, hence contents need to be reloaded). The context does not get any dirty bits to identify this case. This has to be, then, coordinated by the resources that are being shared between the contexts. Add a "curr_pipe" hook in swr_resource that will allow us to identify a MakeCurrent of the above form during swr_update_derived(). At that time, we invalidate the tiles of the new context. The old context, will need to have already store its tiles by that time, which happens during glFlush(). glFlush() is being called at the beginning of MakeCurrent. So, the sequence of operations is: - At the beginning of glXMakeCurrent(), glFlush() will store the tiles of all bound surfaces of the old context. - After the store, a fence will guarantee that the all tile store make it to the surface - During swr_update_derived(), when we validate the new context, we check all resources to see what changed, and if so, we invalidate the current tiles.

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.
