[Intel-gfx] [PATCH v2 0/2] drm/i915: timeline semaphore support

[Lionel Landwerlin]

Hi,

This revision gets rid of the synchronous wait. We now implement the
synchronous wait as part of the userspace driver. A thread is spawned
for each engine and waits for availability of the syncobjs before
calling into execbuffer.

Cheers,
