Yes, that would be nice. Even if we fail to make your card work, it'll
save a few steps for the next person trying to get it functional.

However if we fail to make your card work we should add it to the
card blacklist in
sys/external/bsd/drm2/nouveau/nouveau_pci.c:nouveau_pci_match

(I'm assuming it doesn't know how to recover cleanly)

This failure can be normal.

This is no longer unrecognised upstream.
        case DCB_CONNECTOR_WFD      : return DRM_MODE_CONNECTOR_VIRTUAL;

The git blame points to...

    drm/nouveau/disp: Silence DCB warnings.
    
    Most of these errors seem to be WFD related. Official documentation
    says dcb type 8 is reserved. It's probably used for WFD. Silence
    the warning in either case.
    
    Connector type 70 is stated to be a virtual connector for WiFi
    display. Since we know this, don't warn that we don't.

So, another warning to skip.

> [     4.674760] nouveau0: autoconfiguration error: warn: DRM: failed to create encoder 1/8/0: -19

ret here is -19, -ENODEV.

That means switch (dcbe->type) is not DCB_OUTPUT_TMDS, DCB_OUTPUT_LVDS, DCB_OUTPUT_DP, DCB_OUTPUT_ANALOG.

What outputs do you have?

> [     4.674760] nouveau0: autoconfiguration error: warn: DRM: Unknown-1 has no encoders, removing

It gave up on this output since it doesn't know what to do with it.



Full dmesg, with boot -x, might be more insightful. Does it have more
connectors that are fine?

Thanks!
