This patchset addes two new sets of files to sysfs for POWER architecture. - perf event config format in /sys/devices/cpu/format/event - generic and POWER-specific perf events in /sys/devices/cpu/events/ The format of the first file is already documented in: sysfs-bus-event_source-devices-format Document the format of the second set of files '/sys/devices/cpu/events/*' which would also become part of the ABI. Changelog[v4]: [Jiri Olsa]: Mention that multiple event= like terms can be specified in the 'events' file. [Jiri Olsa]: Remove the documentation for the 'config format' file as it is already documented in 'Documentation/ABI/testing/'. [Jiri Olsa]: Move ABI documentation from 'stable/' to 'testing/' Changelog[v3]: [Greg KH] Include ABI documentation.

Description: Generic performance monitoring events
|
|
|
|
A collection of performance monitoring events that may be
|
|
supported by many/most CPUs. These events can be monitored
|
|
using the 'perf(1)' tool.
|
|
|
|
The contents of each file would look like:
|
|
|
|
event=0xNNNN
|
|
|
|
where 'N' is a hex digit and the number '0xNNNN' shows the
|
|
"raw code" for the perf event identified by the file's
|
|
"basename".

Description: POWER-systems specific performance monitoring events
|
|
|
|
A collection of performance monitoring events that may be
|
|
supported by the POWER CPU. These events can be monitored
|
|
using the 'perf(1)' tool.
|
|
|
|
These events may not be supported by other CPUs.
|
|
|
|
The contents of each file would look like:
|
|
|
|
event=0xNNNN
|
|
|
|
where 'N' is a hex digit and the number '0xNNNN' shows the
|
|
"raw code" for the perf event identified by the file's
|
|
"basename".
|
|
|
|
Further, multiple terms like 'event=0xNNNN' can be specified
|
|
and separated with comma. All available terms are defined in
|
|
the /sys/bus/event_source/devices/<dev>/format file.
