8*6f2c6568SKajol Jain                Each attribute under this group defines a bit range of the
9*6f2c6568SKajol Jain                perf_event_attr.config. Supported attribute are listed
10*6f2c6568SKajol Jain                below::

12*6f2c6568SKajol Jain				event  = "config:0-7"  - event ID
13*6f2c6568SKajol Jain
14*6f2c6568SKajol Jain		For example::

21*6f2c6568SKajol JainDescription:	(RO) Attribute group to describe performance monitoring events
22*6f2c6568SKajol Jain                for the Virtual Processor Dispatch Trace Log. Each attribute in
23*6f2c6568SKajol Jain		this group describes a single performance monitoring event
24*6f2c6568SKajol Jain		supported by vpa_dtl pmu.  The name of the file is the name of
25*6f2c6568SKajol Jain		the event (See ABI/testing/sysfs-bus-event_source-devices-events).
