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. All supported attributes are listed

                below.



				chip = "config:16-31"

				core  = "config:16-31"

				domain = "config:0-3"

				lpar = "config:0-15"

				offset = "config:32-63"

				vcpu = "config:16-31"



               For example,



		PM_PB_CYC =  "domain=1,offset=0x80,chip=?,lpar=0x0"



		In this event, '?' after chip specifies that

		this value will be provided by user while running this event.
