  5Description:	Read-only. Attribute group to describe the magic bits
  6		that go into perf_event_attr.config for a particular pmu.
  7		(See ABI/testing/sysfs-bus-event_source-devices-format).
  8
  9		Each attribute under this group defines a bit range of the
 10		perf_event_attr.config. All supported attributes are listed
 11		below::
 12
 13		    event  = "config:0-11"  - event ID
 14		    evtype = "config:12-15" - event type
 15		    portid = "config:16-23" - event source
 16
 17		For example::
 18
 19		    fab_mmio_read = "event=0x06,evtype=0x02,portid=0xff"
 20
 21		It shows this fab_mmio_read is a fabric type (0x02) event with
 22		0x06 local event id for overall monitoring (portid=0xff).

 35Description:	Read-only. Attribute group to describe performance monitoring
 36		events specific to fme. Each attribute in this group describes
 37		a single performance monitoring event supported by this fme pmu.
 38		The name of the file is the name of the event.
 39		(See ABI/testing/sysfs-bus-event_source-devices-events).
