 4Description:    Read-only. Attribute group to describe the magic bits
 5                that go into perf_event_attr.config for a particular pmu.
 6                (See ABI/testing/sysfs-bus-event_source-devices-format).
 7
 8                Each attribute under this group defines a bit range of the
 9                perf_event_attr.config. All supported attributes are listed
10                below::
11
12				counter_info_version  = "config:16-23"
13				length  = "config:24-31"
14				partition_id  = "config:32-63"
15				request = "config:0-31"
16				sibling_part_id = "config:32-63"
17				hw_chip_id = "config:32-63"
18				offset = "config:32-63"
19				phys_processor_idx = "config:32-63"
20				secondary_index = "config:0-15"
21				starting_index = "config:32-63"
22
23                For example::
24
25		  processor_core_utilization_instructions_completed = "request=0x94,
26					phys_processor_idx=?,counter_info_version=0x8,
27					length=8,offset=0x18"
28
29		In this event, '?' after phys_processor_idx specifies this value
30		this value will be provided by user while running this event.
