Rereading this almost two years later, I realized I completely missed that (a) your setup wasn't actually using irqbypass and (b) you suggested giving userspace a way to disable irqbypass in KVM when it couldn't possibly be utilized. I've proposed adding a module param for other reasons[1]. If that doesn't suffice, KVM could also provide KVM_IRQFD_FLAG_NO_IRQBYPASS (which would also be useful for other reasons). As for the ugly latency problems, I posted a new patch to use xarray to mitigate the issue[2].
