We want prime to only ever create one native gem object for each
dma-buf it sees. This can e.g. happen if multiple processes import the
same foreign dma-buf, e.g. the application imports a yuv frame from
v4l to encode it into a video stream and the compositor imports it
into his fd again to display it with an overlay.
Hence add a bunch of tests which check all the various orders in which
this could happen. Currently they all fail.
Checking flink names is the easiest (and afaik only) way to check
whether we're indeed dealing with the same object.
This checks both ways, i.e. exporting from i915 and from nouveau, each
with two variants of the test: One reuses the prime fd, the other
closes it and creates a new one.

It's purely accidental that importing that same bo to different
drm nouveau fds yields the same handle.

They simply take forever with the current kernel implementation. And
since everyone switched over to the event based interface I don't see
much incentive to try to fix that.
So just disable them.

We need to be careful in case other devices grow an error file in the
future. The first step here is just to check the minor that corresponds
with the debugfs path found for the device
As /sys/class/drm/cardX/error is a new interface for 3.11, we need to be
quiet when it does not exist or else we upset the automated tests.

Since these two tests exercise a working set larger than aperture, they
require stalls which are prone to being interrupted - so interrupt them
and check that everything still works.
Test both debugfs and sysfs error_state interfaces.

Accidentally left in the hack to run the

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
Hiding the initial set_bo() required for the "overwrite-source" tests
lead to a nice bit of hilarity as I missed repeating the initialisation
for the multiple loops of the interruptible version of
"overwrite-source".

Daniel preferred to keep the old tests intact lest we accidentally break
them, and to add the new interruptible tests as new subtests.
In the process also make sure the GPU is idle before starting each loop.

drm/i915: Only clear write-domains after a successful wait-seqno
we need to check for concurrent access with the potential to be
interrupted by a signal. The framework for doing so is already in place,
so just enable it and repeat the tests for longer to give better chance
of being interrupted at just the wrong moment.

I'd been working under the falsehood that we would always generate an
error for an invalid reloc->target_handle before reserving any object.
However, only the execlist is checked up front for validity before
reservation so ENOSPC is a genuine error condition raised by the test.
Fix it so that we stop reporting that limit as a test failure.

Limit the broken handles to UINT32_MAX-4096 so that we can be sure that
they do not alias with a valid handle.

We may fail to set a mode if it fails some hidden constraints, such as
bandwidth on the third pipe. This is expected, so skip testing such
modes.

Certain modes may not be supported by certain combinations of pipes.
This is impossible to determine upfront, and we await an atomic
modesetting query operation. In the meantime, if we fail to set a mode,
just skip that test.

What this test is interested in is the handling of the LUT for very
large arrays, irrespective of whether such batch are actually
executable. So adjust the pass/fail checks to be explicit in the error
they are looking for, so that we do not conflate memory/aperture
pressure as a failure in the LUT API.

Currently when exiting with error, we'll get stuck in a DPMS OFF state
if the error happens while we have DPMS OFF set in the test sequence.
This happens even though we switch back to text mode at exit. This might
be a bug in itself to be fixed later, but in any case we want a working
console, so do an explicit DPMS ON.

Let's not use the 2K variants of the frequencies it does not help
in anything here and the explanations are hopefuly more understandable
this way.
On top of that, I noticed that we can just compute the desired min/max
boundaries for r2 and n2, so use that instead of the two tests to
discard out of range values.
