The generated QEMU QMP reference is now structured as follows:
1.1 Introduction
1.2 Stability Considerations
1.3 Common data types
1.4 Socket data types
1.5 VM run state
1.6 Cryptography
1.7 Block devices
1.7.1 Block core (VM unrelated)
1.7.2 QAPI block definitions (vm unrelated)
1.8 Character devices
1.9 Net devices
1.10 Rocker switch device
1.11 TPM (trusted platform module) devices
1.12 Remote desktop
1.12.1 Spice
1.12.2 VNC
1.13 Input
1.14 Migration
1.15 Transactions
1.16 Tracing
1.17 QMP introspection
1.18 Miscellanea
Section "1.18 Miscellanea" is still too big: it documents 134 symbols.
Section "1.7.1 Block core (VM unrelated)" is also rather big: 128
symbols. All the others are of reasonable size.

# @trace-event-get-state:
|
|
#
|
|
# Query the state of events.
|
|
#
|
|
# @name: Event name pattern (case-sensitive glob).
|
|
# @vcpu: The vCPU to query (any by default; since 2.7).
|
|
#
|
|
# Returns: a list of @TraceEventInfo for the matching events
|
|
#
|
|
# 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.
