Please format like
# @flags: Event Record Flags. See CXL r3.0 Table 8-42 Common Event
# Record Format, Event Record Flags for subfield definitions.
#
# @dpa: Device Physical Address (relative to @path device). Note
# lower bits include some flags. See CXL r3.0 Table 8-43 General
# Media Event Record, Physical Address.
#
# @descriptor: Memory Event Descriptor with additional memory event
# information. See CXL r3.0 Table 8-43 General Media Event
# Record, Memory Event Descriptor for bit definitions.
#
# @type: Type of memory event that occurred. See CXL r3.0 Table 8-43
# General Media Event Record, Memory Event Type for possible
# values.
#
# @transaction-type: Type of first transaction that caused the event
# to occur. See CXL r3.0 Table 8-43 General Media Event Record,
# Transaction Type for possible values.
#
# @channel: The channel of the memory event location. A channel is an
# interface that can be independently accessed for a transaction.
#
# @rank: The rank of the memory event location. A rank is a set of
# memory devices on a channel that together execute a transaction.
#
# @device: Bitmask that represents all devices in the rank associated
# with the memory event location.
#
# @component-id: Device specific component identifier for the event.
# May describe a field replaceable sub-component of the device.
to blend in with recent commit a937b6aa739 (qapi: Reformat doc comments
to conform to current conventions).
