From KHR_fence_sync:
When the condition of the sync object is satisfied by the fence
command, the sync is signaled by the associated client API context,
causing any eglClientWaitSyncKHR commands (see below) blocking on
<sync> to unblock. The only condition currently supported is
EGL_SYNC_PRIOR_COMMANDS_COMPLETE_KHR, which is satisfied by
completion of the fence command corresponding to the sync object,
and all preceding commands in the associated client API context's
command stream. The sync object will not be signaled until all
effects from these commands on the client API's internal and
framebuffer state are fully realized. No other state is affected by
execution of the fence command.
If clients are passing the fence fd (from EGL_ANDROID_native_fence_sync)
to a compositor, that fence must only be signaled once the framebuffer
is resolved and not before as is currently the case.

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.
