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. Supported attribute are listed
                below::

				event  = "config:0-7"  - event ID

		For example::

		  dtl_cede = "event=0x1"

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