VM CP presents the interrupt to Linux, why should Linux then ignore it?
I’m not a kernel internals guy but my view is Linux should propagate any
unsolicited interrupt like this so an application can have the opportunity
to act on it.
If a system wants to use cio_ignore to ignore

Short of having some Linux script querying the virtual reader, is there a

I have RHEL 7.9 setup (on zVM) so I can use the 3270 console instead of

One feature I miss when using the 3215 or 3270 console is tab completion.
Obviously it can’t work the same way as with an xterm type device, but in
the case of 3270 support could we have it use a PF key to simulate pressing
tab and wanting tab completion to kick in? (Just as PF3 switches views,
thing lost by using 3270 support - can’t spool the console. That’s a
different problem for a different thread.
