# @cxl-inject-general-media-event:
#

# specified via the log parameter.
#
# @path: CXL type 3 device canonical QOM path
#
# @log: event log to add the event to
#
# @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

#
# @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.
