In the Power7 PMU guide: https://www.power.org/documentation/commonly-used-metrics-for-performance-analysis/ PM_BRU_MPRED is referred to as PM_BR_MPRED. It fixed the typo by changing the name of the event in kernel and documentation accordingly. This patch changes the ABI, there are some reasons I think it's ok: - It is relatively new interface, specific to the Power7 platform. - No tools that we know of actually use this interface at this point (none are listed near the interface). - Users of this interface (eg oprofile users migrating to perf) would be more used to the "PM_BR_MPRED" rather than "PM_BRU_MPRED". - These are in the ABI/testing at this point rather than ABI/stable, so hoping we have some wiggle room.

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.
