The names of the idle states in the output of cpupower monitor command are truncated to 4 characters. On POWER9, this creates ambiguity as the states are named "stop0", "stop1", etc. root:~# cpupower monitor |Idle_Stats PKG |CORE|CPU | snoo | stop | stop | stop | stop | stop | stop 0| 0| 0| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 1.90 0| 0| 1| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 0| 0| 2| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 0| 0| 3| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 This patch modifies the output to print the state name that results in a legible output. The names will be printed with atmost 1 padding in left. root:~# cpupower monitor | Idle_Stats PKG|CORE| CPU|snooze|stop0L| stop0|stop1L| stop1|stop2L| stop2 0| 0| 0| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.72 0| 0| 1| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 0| 0| 2| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 0| 0| 3| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00| 0.00 This patch does not affect the output for intel.
