Caution
This begs the questioncould a WAKEUP type function be written for
zLinux when it is running as a guest of z/VM?

But I don't know if the Linux device drivers will generate UDEV events
based on it. It would be nice if they did.
They don't, unfortunately.

I just ran a test, and it doesn't seem to do so.

If the message you get from CP is an SMSG, then you can have udev rules
that would get triggered to check

(Didn't we have a conversation about this here a few weeks/months ago?)
Aside from an IMSG, the reader will get an unsol
[sigh]
Now that you ask, I'll have to dig to remember it. It's one of the
neatest things about z/VM virtual machines, but not universally
applicable to Linux (or even Linux on Z).
All the DuckDuck hits are for the terminal server, and that's completely
different.
It's *not* the smsgiucv_app driver
If you use the fsiucv driver I wrote you can use it to field stuff from *MSG.

Rick, I can? Pray tell, how? If I was doing this on CMS I would just use
WAKEUP (or something like it) to run something when a RDR arrived.
Many thanks.

IMSGs
But you can trap those too.

Hi Dave,
the principle is the same for all Linux on Z distros (well, the sudo piece
is typical for Ubuntu ;-)
Enable the corresponding ccw devices:
sudo chzdev -e 0.0.000c-0.0.000e
and you'll get these devices:
ls -l /dev/vm*
crw--- 1 root root 10, 122 Apr 22 08:06 /dev/vmcp
crw--- 1 root
Hello, all.
How can I get automatically notified in a z/Linux guest (in this case
Ubuntu 20.04) when a rdr file arrives for it?
Many thanks.
