  15 Description:    Generic performance monitoring events
  16
  17                 A collection of performance monitoring events that may be
  18                 supported by many/most CPUs. These events can be monitored
  19                 using the 'perf(1)' tool.
  20
  21                 The contents of each file would look like:
  22
  23                         event=0xNNNN
  24
  25                 where 'N' is a hex digit and the number '0xNNNN' shows the
  26                 "raw code" for the perf event identified by the file's
  27                 "basename".

  44 Description:    POWER-systems specific performance monitoring events
  45
  46                 A collection of performance monitoring events that may be
  47                 supported by the POWER CPU. These events can be monitored
  48                 using the 'perf(1)' tool.
  49
  50                 These events may not be supported by other CPUs.
  51
  52                 The contents of each file would look like:
  53
  54                         event=0xNNNN
  55
  56                 where 'N' is a hex digit and the number '0xNNNN' shows the
  57                 "raw code" for the perf event identified by the file's
  58                 "basename".
  59
  60                 Further, multiple terms like 'event=0xNNNN' can be specified
  61                 and separated with comma. All available terms are defined in
  62                 the /sys/bus/event_source/devices/<dev>/format file.
