4Description:    Read-only. Attribute group to describe the magic bits
5                that go into perf_event_attr.config for a particular pmu.

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

21Description:    Read-only. Attribute group to describe performance monitoring
22                events for the Virtual Processor Area events. Each attribute
23                in this group describes a single performance monitoring event
24                supported by vpa_pmu. The name of the file is the name of
25                the event (See ABI/testing/sysfs-bus-event_source-devices-events).
