Wouldn't we want a whole bunch of new tracepoints in this case? (almost all of the existing ones with the extra vcpu_id field). Right now we have 3 types of events: - events with no vcpu at all // nil - events with vcpu_pc // "0x%016lx", __entry->vcpu_pc - events with (void *)vcpu // "vcpu: %p", __entry->vcpu It might be helpful if we could filter out events by vcpu_id. But this, basically, doubles the number of events in the ringbuffer. -ss
