[PATCH] drm/edid: Add quirk for OSVR HDK 2.0

[PATCH] drm/edid: Add quirk for OSVR HDK 2.0

[Ralph Campbell]

The OSVR virtual reality headset HDK 2.0 uses a different EDID
vendor and device identifier than the HDK 1.1 - 1.4 headsets.
Add the HDK 2.0 vendor and device identifier to the quirks table so
that window managers do not try to display the desktop screen on the
headset display.

I don't know how many of these VR headsets are still around but I have a
working one and I saw and entry for HDK 1.x so I thought it would be good
to add HDK 2.0.

At some point in time we requested bugs to be filed about quirks, with
EDIDs attached, so we could look at them later, and maybe remove the
quirks.

The headset non-desktop thing started off as a quirk, but since then
we've added both Microsoft VSDB and DisplayID primary use as ways to
indicate this without quirks.

BR,
Jani.

If you want me to file a bug, I can do that and I have the EDID too.
Where would I file it?

I did see the DisplayID 2.0 code. This headset is no longer being
manufactured so updating the EDID is not practical.

I suppose at https://gitlab.freedesktop.org/drm/misc/-/issues

We should then reference the issue in the commit message (no need to
resend, this can be added while applying).

I'm not saying the EDID should be updated, just that we might drop the
quirk if we find another generic way to identify non-desktops that
covers the EDID in question.

If the device isn't covered by the existing mechanisms, I'm not opposed
to merging as-is, with the issue reference added.


Thanks,
Jani.

Thanks, I created issue #30
"OSVR virtual reality headset HDK 2.0 not recognized as a non-desktop display"
