If userspace is running an synchronously atomic commit and interrupts the
atomic operation during fence_wait() it will hang until the timer expires,
so here we change the wait to be interruptible so it stop immediately when
userspace wants to quit.

Hi,
Currently the Linux Kernel only have an implicit fencing mechanism, through
reservation objects, in which the fences are attached directly to buffers
operations and userspace is unaware of what is happening. On the other hand
explicit fencing exposes fences to the
From: Gustavo Padovan
Support DRM out-fences by creating a sync_file with a fence for each CRTC
that sets the OUT_FENCE_PTR property.
We use the out_fence pointer received in the OUT_FENCE_PTR prop to send
the sync_file fd back to userspace.
The sync_file and fd are allocated/created before
From: Gustavo Padovan
Create one timeline context for each CRTC to be able to handle out-fences
and signal them. It adds a few members to struct drm_crtc: fence_context,
where we store the context we get from fence_context_alloc(), the
fence seqno and the fence lock, that we pass in fence_init
From: Gustavo Padovan
There is now a new property called FENCE_FD attached to every plane
state that receives the sync_file fd from userspace via the atomic commit
IOCTL.
The fd is then translated to a fence (that may be a fence_collection
subclass or just a normal fence) and then used by DRM
From: Gustavo Padovan
If the event gets canceled we also need to put away the fence
reference it holds.

Add an extra arg to drm_atomic_helper_wait_for_fences() to inform
if fence_wait() should be called interruptible or uninterruptible.

This interface is hidden from kernel headers and it is intended for use
only for testing. So testers would have to add the ioctl information
internally. This is to prevent misuse of this feature.
