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.
