[PATCH i-g-t 1/2] lib: Spin fast, retire early

[Chris Wilson]

When using the pollable spinner, we often want to use it as a means of
ensuring the task is running on the GPU before switching to something
else. In which case we don't want to add extra delay inside the spinner,
but the current 1000 NOPs add on order of 5us, which is often larger
than the target latency.

[PATCH i-g-t 2/2] igt/gem_sync: Alternate stress for nop+sync

[Chris Wilson]

Apply a different sort of stress by timing how long it takes to sync a
second nop batch in the pipeline. We first start a spinner on the
engine, then when we know the GPU is active, we submit the second nop;
start timing as we then release the spinner and wait for the nop to
complete.

As with every other gem_sync test, it serves two roles. The first is
that it checks that we do not miss a wakeup under common stressful
conditions (the more conditions we check, the happier we will be that
they do not occur in practice). And the second role it fulfils, is that
it provides a very crude estimate for how long it takes for a nop to
execute from a running start (we already have a complimentary estimate
for an idle start).

  introduced in IGTPW_1489_full, please notify your bug team to allow them
  to document this new failure mode, which will reduce false positives in CI.
