  25. 		where 'N' is a hex digit and the number '0xNNNN' shows the

  44. Description:	POWER-systems specific performance monitoring events
    45. 

  45. 

  46. 		A collection of performance monitoring events that may be
    47. 

  47. 		supported by the POWER CPU. These events can be monitored
    48. 

  48. 		using the 'perf(1)' tool.
    49. 

  49. 

  50. 		These events may not be supported by other CPUs.
    51.

  52. 		The contents of each file would look like:
    53. 

  53. 

  54. 			event=0xNNNN
    55. 

  55. 

  56. 		where 'N' is a hex digit and the number '0xNNNN' shows the

    58. 

  58. 		"basename".
    59. 

  59. 

  60. 		Further, multiple terms like 'event=0xNNNN' can be specified
    61. 

  61. 		and separated with comma. All available terms are defined in
    62. 

  62. 		the /sys/bus/event_source/devices/<dev>/format file.
