--- Comment #4 from Stuart Summers <stuart.summers at intel.com> ---
Sent that previous comment a little too quickly... It looks like we aren't
actually sending those 0's in the first place, in addition to my off-by-one
(given we are taking 0 - 1, not 0) miss:
  (w && h) ? "(iiiiii)" : "(iinnnn)",

>From chameleond, this will autofill x, y, width, and height based on the
current resolution. Maybe the resolution was misconfigured? Or perhaps there's
an issue in the chamelium FPGA?

I still think it would be interesting here to get the chameleond log (see
request here: https://gitlab.freedesktop.org/gfx-ci/i915-infra/issues/29 + the
recent patch I posted to igt). There is quite a bit of state logging in
chameleond with that patch run locally with --d.

The only other thing I see interesting in the logs is this, just before the
error:
(kms_chamelium:2877) igt_chamelium-DEBUG: Chamelium needs FSM, handling

I don't see that when I run locally. Maybe we're getting a spurious hotplug
event while trying to capture video? Or maybe the video capture is taking to
long and/or hung for some reason, causing the hotplug to timeout?
