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.
