Thank you Mark. 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 the reader, that’s a preference.
