I think something this is the best option for the moment.
Posted-interrupts are only on E5 v4 and Xeon-D.
It makes a big difference with network cards (and GPUs).
Does anyone know if AVIC or some other Ryzen feature provides for
posted-interrupts?
By "posted interrupts" do you mean that they get delivered directly
to
the VM, bypassing the host? If so, then yes enabling AVIC does
provide that behavior. With AVIC enabled (kvm_amd.avic=1), I do not
see the counters in /proc/interrupts increment for passed-through
devices.
Yes, that's it. Fantastic. Thanks!
This does make me interested in trying a Ryzen setup... the i7s AFAIK
don't have posted-interrupts.
