Comment 1 Martin Peres 2019-06-18 10:14:10 UTC 
The machine has 3 displays connected and it is currently reporting 3 displays.

Tomi says he has not changed the configuration of the machine last week. Assigning Jani because he may have updated the BIOS without and forgot to re-enable DP.

We need to know what changed on this machine, and if nothing changed, then we have a problem in our driver that would prevent connectors from being discovered.

Plenty of issues to fix here to prevent future issues like this!

Sorry, but the bug is very valid. It happened 3 times in the same shard...

As you said IRL, some of the *2p* tests are passing on the same shard, which might exclude HW change (unless someone rebooted the chamelium while running the shard).

So, we now need to investigate in the kernel logs what might have happened. Disappearing outputs is cause for concern.

Comment 9 emersion 2019-06-20 13:26:02 UTC 
I thought that maybe this is an issue with the Chamelium teardown sequence. However it doesn't seem to be the case.

* * *

More details:

We rely on the Chamelium board for providing additional outputs. However by default all Chamelium ports are disabled (unplugged). One needs to send a Plug call to the Chamelium API to enable them.

(Side note: rebooting the Chamelium will disable all Chamelium ports)

In order to be able to use these ports, we need to re-enable them after all audio tests. This is something we do in chamelium_exit_handler. I checked that it's properly executed after a failed test.

This issue is occurring 100% and causing lot of tests to skip even though fi-icl-u2 has two display's connected.

Comment 31 emersion 2019-09-04 13:25:02 UTC 
Applied the workaround described in https://bugs.chromium.org/p/chromium/issues/detail?id=977994#c4 to fi-icl-u2's chamelium board.

Will monitor CI results to see if it mitigates the issue.

If not, maybe a better solution would be to enable all ports before running IGT tests.
