since this is done :-), I think hvm_do_resume can be clean up more since
HVM vcpu can''t be waked up by interrupts now.
And you mentioned that we can batch interrupts notification hypercalls,
so is it OK to batch IO events done notification hypercalls too?

Yes. The biggest win in qemu I suspect will be to remember the current state
of each ''interrupt wire'' and only do a hypercall when the
state changes.
Feel free to generate patches to maintain that shaodw state, and to do
batched multicalls.
