 Query the state of events.
 
+Arguments:
+
+- "name": Event name pattern (json-string).
+- "vcpu": The vCPU to query, any vCPU by default (json-int, optional).
+
+An event is returned if:
+- its name matches the "name" pattern, and
+- if "vcpu" is given, the event has the "vcpu" property.
+
+Therefore, if "vcpu" is given, the operation will only match per-vCPU events,
+returning their state on the specified vCPU. Special case: if "name" is an exact
+match, "vcpu" is given and the event does not have the "vcpu" property, an error
+is returned.

 Example:
 
 -> { "execute": "trace-event-get-state", "arguments": { "name": "qemu_memalign" } }
