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.
