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).
