| |
---Steps to Reproduce---
1.Execute the cpupower monitor command to fetch all the Idle_Stats values.
root:~# cpupower monitor |Idle_Stats PKG |CORE|CPU | snoo | stop | stop 0| 8| 0| 0.00| 0.00| 2.79 0| 8| 1| 0.00| 0.00| 70.68
User interpret it as 2 columns for stop Idle_stats.
root:/sys/devices/system/cpu/cpu8/cpuidle# cat */name snooze stop0_lite stop1_lite
cpupower monitor now shows full state name and adjust colomn width.
root:~/linux/tools/power/cpupower# cpupower monitor |Idle_Stats PKG |CORE|CPU |snooze|stop0_lite|stop1_lite 0| 8| 0| 0.00| 0.00| 99.83 0| 8| 1| 0.00| 0.00| 43.82 0| 8| 2| 0.00| 0.00| 102.1 0| 8| 3| 0.00| 0.00| 96.56
tested on x86 as well.
