the number of iterations used, for the majority of tests that are

3. calculate the new min cdclk for each plane in the state

So far we've sort of protected the global state under dev_priv with
the connection_mutex. I wan to change that so that we can change the
cdclk even for pure plane updates. To that end let's formalize the
protection of the global state to follow what I started with the cdclk
code already (though not entirely properly) such that any crtc mutex
will suffice as a read lock, and all crtcs mutexes act as the write
lock.
We'll also pimp intel_atomic_state_clear() to clear the entire global
state, so that we don't accidentally leak stale information between
the locking retries.
As a slight optimization we'll only lock the crtc mutexes to protect
the global state, however if and when we actually have to poke the
hw (eg. if the actual cdclk changes) we must serialize commits
across all crtcs so that a parallel nonblocking commit can't get
ahead of the cdclk reprogamming. We do that by adding all crtcs to
the state.
TODO: the old global state examined during commit may still
be a problem since it always looks at the _latest_ swapped state
in dev_priv. Need to add proper old/new state for that too I think.

Normally, we rely on our hangcheck to prevent persistent batches from
hogging the GPU. However, if the user disables hangcheck, this mechanism
breaks down. Despite our insistence that this is unsafe, the users are
equally insistent that they want to use endless batches and will disable
the hangcheck mechanism. We are looking at replacing hangcheck, in the
next patch, with a softer mechanism, that sends a pulse down the engine
to check if it is well. We can use the same preemptive pulse to flush an
active context off the GPU upon context close, preventing resources
being lost and unkillable requests remaining on the GPU after process
termination.

drm/i915/execlists: Force preemption
If the preempted context takes too long to relinquish control, e.g. it
is stuck inside a shader with arbitration disabled, evict that context
with an engine reset. This ensures that preemptions are reasonably
responsive, providing a tighter QoS for the more important context at
the cost of flagging unresponsive contexts more frequently (i.e. instead
of using an ~10s hangcheck, we now evict at ~100ms). The challenge of
lies in picking a timeout that can be reasonably serviced by HW for
typical workloads, balancing the existing clients against the needs for
responsiveness.
Note that coupled with timeslicing, this will lead to rapid GPU "hang"
detection with multiple active contexts vying for GPU time.
