   5 Description:    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).

  35 Description:    Read-only. Attribute group to describe performance monitoring
