This series looks good to me. Before I give my Acked-by for this series, can you confirm that it is possible to transmit the Image View On message on both outputs of the RPi4 when the HPD is low? See section "CEC Without HPD" in https://hverkuil.home.xs4all.nl/cec-status.txt on how to test this with a Pulse-Eight device. This should work.

Yes, it looks good. Make sure you test this for both outputs of the RPi4. If it works for both, then you can add my Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> for this series. Very nice work, thank you for doing this! Regards, Hans > > Maxime >

Make sure you test this for both outputs of the RPi4. It's a good thing you asked, I don't appear to get CEC interrupts from HDMI1. I'll fix it and send another version (probably not before the end of december though). > If it works for both, then you can add my > > Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> > > for this series. > > Very nice work, thank you for doing this! Thanks! I'll hold your a-b until the next version though, fixing hdmi1 might change a few things. Maxime
