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.
