The test says:
/*
* There should *not* be an artificial limit to the number
* of open()s you can do on a V4L2 device node. So test whether
* you can open a device node at least 100 times.
*
* And please don't start rejecting opens in your driver at 101!
* There really shouldn't be a limit in the driver.
*
* If there are resource limits, then check against those limits
* where they are actually needed.
*/
So might have been acceptable for old venus, but not for iris since its a new
driver. Discussion and solution is needed. This is, I suppose, limiting the
number of decode sessions ? I personally find that method easier for userspace
then let say failing at streamon or something, but clearly a discussion need to
take place here as this is failing the compliance.

These helper make it possible to introduce regressions, did you run compliance
tests against a venus based system to make sure ?
On top of this, initial submission and core modification to CODEC drivers are
now expected to be accompanied with fluster [0] results. This will help later
with integration testing enablement into KernelCI and will show that you made
sure the new driver is performing fairly well and is comparable to venus
(results available in Kernel CI, let me know if you have a hard time finding the
results).
[0] https://github.com/fluendo/fluster kernel CI uses GStreamer decoder, but
ffmpeg support is also available in the test runner.
