This test creates compute vms, binds a couple of bos and an engine each,
thus redying it for execution. However, VRAM memory is over-
committed and while there is still nothing to execute, an eviction
will trigger the VM's rebind worker to rebind the evicted bo, which
will in turn trigger another eviction and so on.
Since we don't have eviction stats yet we need to watch "top" for
the rebind kworkers using a lot of CPU while the test idles.
The correct driver behaviour should be not to rebind anything unless
there is work queued on one of the VM's compute engines.
v2:
- Use the ALIGN macro for aligning
- Reduce the idle pause duration to 10s. (Matthew Brost)
- Add an IGT_TEST_DESCRIPTION()
- Explicity use gt0 for testing.
- Skip if no VRAM available.
