Add plumbing to allow creation of per display surface out fence.
Currently enabled only on android, since the system expects a valid
fd in ANativeWindow::{queue,cancel}Buffer. We pass a fd of -1 with
which native applications such as flatland fail. The patch enables
explicit sync on android and fixes one of the functional issue for
apps or buffer consumers which depend upon fence and its timestamp.
v2: a) Also implement the fence in cancelBuffer.
b) The last sync fence is stored in drawable object
rather than brw context.
c) format clear.
v3: a) Save the last fence fd in DRI Context object.
b) Return the last fence if the batch buffer is empty and
nothing to be flushed when _intel_batchbuffer_flush_fence
c) Add the new interface in vbtl to set the retrieve fence
v3.1 a) close fd in the new vbtl interface on none Android platform
v4: a) The last fence is saved in brw context.
b) The retrieve fd is for all the platform but not just Android
c) Add a uniform dri2 interface to initialize the surface.
v4.1: a) make some changes of variable name.
b) the patch is broken into two patches.
v4.2: a) Add a deinit interface for surface to clear the out fence
v5: a) Add enable_out_fence to init, platform sets it true or
false
b) Change get fd to update fd and check for fence
c) Commit description updated
v6: a) Heading and commit description updated
b) enable_out_fence is set only if fence is supported
c) Review comments on function names
d) Test with standalone patch, resolves the bug
v6.1: Check for old display fence reverted
v6.2: enable_out_fence initialized to false by default,
dri2_surf_update_fence_fd updated, deinit changed to fini

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.
