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.
