5724142f8SWu HaoDescription:	Read-only. Attribute group to describe the magic bits
6724142f8SWu Hao		that go into perf_event_attr.config for a particular pmu.
7724142f8SWu Hao		(See ABI/testing/sysfs-bus-event_source-devices-format).
8724142f8SWu Hao
9724142f8SWu Hao		Each attribute under this group defines a bit range of the
10724142f8SWu Hao		perf_event_attr.config. All supported attributes are listed
11*002a9c2fSMauro Carvalho Chehab		below::
12724142f8SWu Hao
13724142f8SWu Hao		    event  = "config:0-11"  - event ID
14724142f8SWu Hao		    evtype = "config:12-15" - event type
15724142f8SWu Hao		    portid = "config:16-23" - event source
16724142f8SWu Hao
17*002a9c2fSMauro Carvalho Chehab		For example::
18724142f8SWu Hao
19724142f8SWu Hao		    fab_mmio_read = "event=0x06,evtype=0x02,portid=0xff"
20724142f8SWu Hao
21724142f8SWu Hao		It shows this fab_mmio_read is a fabric type (0x02) event with
22724142f8SWu Hao		0x06 local event id for overall monitoring (portid=0xff).

35724142f8SWu HaoDescription:	Read-only. Attribute group to describe performance monitoring
36724142f8SWu Hao		events specific to fme. Each attribute in this group describes
37724142f8SWu Hao		a single performance monitoring event supported by this fme pmu.
38724142f8SWu Hao		The name of the file is the name of the event.
