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,

+ .args_type = "name:s,enable:b,ignore-unavailable:b?,vcpu:i?",
.mhandler.cmd_new = qmp_marshal_trace_event_set_state,
},
Set the state of events.
+Arguments:
+
+- "name": Event name pattern (json-string).
+- "enable": Whether to enable or disable the event (json-bool).
+- "ignore-unavailable": Whether to ignore errors for events that cannot be
+ changed (json-bool, optional).
+- "vcpu": The vCPU to act upon, all vCPUs by default (json-int, optional).
+
+An event's state is modified 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,
+setting 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
