OSVR virtual reality headset HDK 2.0 not recognized as a non-desktop display
The OSVR virtual reality headset HDK 2.0 uses a different EDID vendor and device identifier than the HDK 1.1 - 1.4 headsets and is not listed in the edid_quirk_list[] table although the earlier HDK 1.1 - 1.4 headsets are listed. This means the headset is used as a normal desktop display.
Here is the EDID: 00 ff ff ff ff ff ff 00 06 af 11 11 b5 02 00 00 1e 1a 01 03 80 0d 0f 78 ea a8 7d ab 54 3c b6 21 10 4c 4f 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 a4 6a 70 56 81 b0 0c 40 5c 05 63 00 82 96 00 00 00 18 00 00 00 ff 00 56 30 30 31 0a 20 20 20 20 20 20 20 20 00 00 00 fc 00 4f 53 56 52 20 48 44 4b 32 0a 20 20 20 00 00 00 fd 00 14 78 01 ff 1d 00 0a 20 20 20 20 20 20 01 cd

If you have time, can you run this script? This would dump the DisplayID if any.

Took me a while to figure out what was going on!
I'm running Fedora 38 with nouveau and a NVIDIA GTX 1080 Ti. I see /sys/class/drm/card0-HDMI-A-1 as the connector to the headset but no ddc directory under it.
