[PATCH i-g-t] i915/gem_ctx_engine: Prevent preemption

[PATCH i-g-t] i915/gem_ctx_engine: Prevent preemption

[Chris Wilson]

In order to pin the engine as busy, we have to prevent the kernel from
executing other independent work ahead of our plug, so tell the spinner
to not allow preemption.

The no-op batch preempts the spinner? How does that affect the busy 
check on the no-op batch?

We are checking the second batch in the pipeline, expecting it to be
blocked by the already executing spinner on the engine of interest.
There is no dependency between the two batches, just order of
submission, hence the kernel ends up executing the second no-op batch
after the first batch's timeslice expired.

Yes of course.. but even without timeslicing I think we could have this 
assumption spinner plugs in a lot of places.

Yes. In the places where I've thought about this plugging issue, we
issue BIGNUM high priority requests. However, this is the only
consistent failure atm, no doubt more will turn up.
