+Description:	(RO) 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 is listed
+		below::
+		  event  = "config:0-4"  - event ID
+
+		For example::
+			ctl_res_cnt = "event=0x1"

+Description:	(RO) Attribute group to describe performance monitoring events
+                for the nvdimm memory device. Each attribute in this group
+                describes a single performance monitoring event supported by
+                this nvdimm pmu.  The name of the file is the name of the event.
+                (See ABI/testing/sysfs-bus-event_source-devices-events). A
+                listing of the events supported by a given nvdimm provider type
+                can be found in Documentation/driver-api/nvdimm/$provider.
