+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).
