The KVM XIVE device implements a "xics-on-xive" interface, the XICS hcalls
on top of the XIVE native PowerNV (OPAL) interface, and ...

... the KVM XIVE *native* device implements a "xive" interface", the one
using MMIOs for interrupt management.

May be it's worth making the difference in the user interface ?


The content of these xive files is quite different so I kept the same
name as before, I can change if you think it is worth it, should I?

It's not very important. The contents differ anyhow.

You
are probably the only person who looked at it recently (or ever?) :) Thanks,

and you just did ! :)

Cheers,
