     33# @name: Event name.
     34# @state: Tracing state.
     35# @vcpu: Whether this is a per-vCPU event (since 2.7).
     36#
     37# An event is per-vCPU if it has the "vcpu" property in the "trace-events"
     38# files.

     46# @trace-event-get-state:
     47#
     48# Query the state of events.
     49#
     50# @name: Event name pattern (case-sensitive glob).
     51# @vcpu: The vCPU to query (any by default; since 2.7).
     52#
     53# Returns: a list of @TraceEventInfo for the matching events
     54#
     55#          An event is returned if:
     56#
     57#          - its name matches the @name pattern, and
     58#          - if @vcpu is given, the event has the "vcpu" property.
     59#
     60#          Therefore, if @vcpu is given, the operation will only match per-vCPU events,
     61#          returning their state on the specified vCPU. Special case: if @name is an
     62#          exact match, @vcpu is given and the event does not have the "vcpu" property,
     63#          an error is returned.
