This consists of simply storing the most recent deadline, and adding an
ioctl to retrieve the deadline. This can be used in conjunction with
the SET_DEADLINE ioctl on a fence fd for testing. Ie. create various

This should probably be re-written by someone who knows the i915
request/timeline stuff better, to deal with non-immediate deadlines.
But as-is I think this should be enough to handle the case where
we want syncobj waits to trigger boost.

From: Rob Clark
This series adds deadline awareness to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.
This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:

Because eb_composite_fence_create() drops the fence_array reference
after creation of the sync_file, only the sync_file holds a ref to the
fence. But fd_install() makes that reference visable to userspace, so
it must be the last thing we do with the fence.

A userspace with multiple threads racing I915_GEM_SET_TILING to set the
tiling to I915_TILING_NONE could trigger a double free of the bit_17
bitmask. (Or conversely leak memory on the transition to tiled.) Move

Adding the vm to the vm_xa table makes it visible to userspace, which
could try to race with us to close the vm. So we need to take our extra
reference before putting it in the table.

From: Rob Clark
gem_context_register() makes the context visible to userspace, and which
point a separate thread can trigger the I915_GEM_CONTEXT_DESTROY ioctl.
So we need to ensure that nothing uses the ctx ptr after this. And we
need to ensure that adding the ctx to the xarray is the *last
