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.
