[Mesa-dev] [RFC v2 0/5] DRI3 v1.2, ANV X11 explicit fences

[Louis-Francis Ratté-Boulianne]

This patchset makes use of Jason Ekstrand's recent work on SYNC_FD
semaphores and DRI3 v1.2 support for DMA fences:
https://lists.x.org/archives/xorg-devel/2017-September/054770.html

This is the second version of this patchset. For more context, see:
https://lists.freedesktop.org/archives/mesa-dev/2017-August/168201.html

The main changes compared to previous iteration are:

 - DMA fences are now split to a different DRI3 version (v1.2)

 - Check if Present protocol has the right version (v1.2)

 - Correctly initialize the fences and do the right thing when
   the X server doesn't support explicit fencing.
