I'm talking about the guest/host interface. So you have one vmexit and

I understood what you were speaking. I mean, perf generic codes operate perf_event
one by one. At low layer, we just know one perf_event before calling hypercall to
vmexit to host kernel.
Ah.
We might fix that by having the perf ops work on guest memory, and add a
commit that transfers them to the host. But this is complicated and can
be left for later.
