0005 Description: Read-only. Attribute group to describe the magic bits
0006 that go into perf_event_attr.config for a particular pmu.
0007 (See ABI/testing/sysfs-bus-event_source-devices-format).
0008
0009 Each attribute under this group defines a bit range of the
0010 perf_event_attr.config. All supported attributes are listed
0011 below::
0012
0013 event = "config:0-11" - event ID
0014 evtype = "config:12-15" - event type
0015 portid = "config:16-23" - event source
0016
0017 For example::
0018
0019 fab_mmio_read = "event=0x06,evtype=0x02,portid=0xff"
0020
0021 It shows this fab_mmio_read is a fabric type (0x02) event with
0022 0x06 local event id for overall monitoring (portid=0xff).

0035 Description: Read-only. Attribute group to describe performance monitoring
0036 events specific to fme. Each attribute in this group describes
0037 a single performance monitoring event supported by this fme pmu.
0038 The name of the file is the name of the event.
0039 (See ABI/testing/sysfs-bus-event_source-devices-events).
