Description:	Read-only. Attribute group to describe the magic bits
		that go into perf_event_attr.config for a particular pmu.
		(See ABI/testing/sysfs-bus-event_source-devices-format).

		Each attribute under this group defines a bit range of the
		perf_event_attr.config. All supported attributes are listed
		below::

		    event  = "config:0-11"  - event ID
		    evtype = "config:12-15" - event type
		    portid = "config:16-23" - event source

		For example::

		    fab_mmio_read = "event=0x06,evtype=0x02,portid=0xff"

		It shows this fab_mmio_read is a fabric type (0x02) event with
		0x06 local event id for overall monitoring (portid=0xff).

Description:	Read-only. Attribute group to describe performance monitoring
		events specific to fme. Each attribute in this group describes
		a single performance monitoring event supported by this fme pmu.
		The name of the file is the name of the event.
		(See ABI/testing/sysfs-bus-event_source-devices-events).

		All supported performance monitoring events are listed below.
