[RFC PATCH 0/2] guest exploitation of the XIVE interrupt controller

[Cédric Le Goater]

Hello,

I am currently working on a XIVE model for the pseries QEMU machine
and I started hacking Linux to have something to test with. 

Here's a first draft of XIVE support for the guest. This is work in
progress, only tested with the QEMU XIVE model I am working
on. Feedback most welcome. 

Thanks,

C.
