With lockdep enabled, the driver overhead is enormous and we need to
slow down the GPU to compenstate (otherwise the GPU is already idle when
we expect busyness). So do more work per batch.

A little more inelegant as we can't control the delay very well, but it
should prove more vesatile and broaden the test coverge (and still be
quick enough for basic).

When we aren't deliberately injecting hangs, we don't expect to see any
GPU hang. Detect them and fail early.

If we listen to the uevents from the kernel, we can detect when the GPU
hangs. This requires us to fork a helper process to do so and send a
signal back to the parent.

"Leak" the objects from each test until each process has allocated
enough objects to consume all of RAM.
Doing so from each process not only ensures we do stress the allocation
paths, but also obsoletes the separate purgeable helper.

This test exercise purely to exercise the shrinker under some common
stress (i.e. paths leading to i915_gem_object_get_pages()). We try to
fill the entirely of memory split amongst many processes so that each
individual process only consumes a small fraction of RAM (less than the
mappable aperture) and a single process should not be individually
blamed.
Based on an idea to have a seperate set of memory stress tests by Piotr
Luc.

Add a couple of all-engine busy tests in order to exercise coherency and
general bugs across suspend. (In particular, I expect this to trigger a
fresh case of lockdeps on Braswell, as well as the usual battery of
missing rpm references. This is an exerciser for my lockless-suspend

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
To simplify and speed up running interruptible tests, use a custom
ioctl() function that control the signaling and detect when we need no
more iterations to trigger an interruption.
We use a realtime timer to inject the signal after a certain delay,
increasing the delay on every loop to try and exercise different code
paths within the function. The first delay is very short such that we
hopefully enter the kernel with a pending signal.
Clients should use
struct igt_sigiter iter = {};
while (igt_sigiter_repeat(&iter, enable_interrupts=true))
do_test()
to automatically repeat the test until we can inject no more signals
into the ioctls. This is condensed into a macro
igt_interruptible(enable_interrupts=true)
do_test();
for convenience.

This patch adds ioctl-errors subtest to be used for exercising prime sync ioctl
errors.
The subtest constantly interrupts via signals a function doing concurrent blit
to stress out the right usage of prime_sync_*, making sure these ioctl errors
are handled accordingly. Important to note that in case of failure (e.g. in a
case where the ioctl wouldn't try again in a return error) this test does not
reliably catch the problem with 100% of accuracy.
v2: fix prime sync direction when reading mmap'ed file.
v3: change the upper bound using time rather than loops
