[Intel-gfx] [CI 1/3] drm/i915: Make exclusive awaits on i915_active optional

[Intel-gfx] [CI 1/3] drm/i915: Make exclusive awaits on i915_active optional

[Chris Wilson]

Later use will require asynchronous waits on the active timelines, but
will not utilize an async wait on the exclusive channel. Make the await
on the exclusive fence explicit in the selection flags.

[Intel-gfx] [CI 2/3] drm/i915: Allow asynchronous waits on the i915_active barriers

[Chris Wilson]

Allow the caller to also wait upon the barriers stored in i915_active.

v2: Hook up i915_request_await_active(I915_ACTIVE_AWAIT_BARRIER) as well
for completeness, and avoid the lazy GEM_BUG_ON()!

v3: Pull flush_lazy_signals() under the active-ref protection as it too
walks the rbtree and so we must be careful that we do not free it as we
iterate.

[Intel-gfx] [CI 3/3] drm/i915/gem: Wait until the context is finally retired before releasing engines

[Chris Wilson]

If we want to percolate information back from the HW, up through the GEM
context, we need to wait until the intel_context is scheduled out for
the last time. This is handled by the retirement of the intel_context's
barrier, i.e. by listening to the pulse after the notional unpin. So
wait until the intel_context is finally retired before releasing the
engine, so that we can inspect the final context state and pass it on.
