Prarit Bhargava d0e4a193c3 tools/power/cpupower: allow running without cpu0 ... Linux-3.7 added CONFIG_BOOTPARAM_HOTPLUG_CPU0, allowing systems to offline cpu0. But when cpu0 is offline, cpupower monitor will not display all processor and Mperf information: [root@intel-skylake-dh-03 cpupower]# ./cpupower monitor WARNING: at least one cpu is offline |Idle_Stats CPU | POLL | C1-S | C1E- | C3-S | C6-S | C7s- | C8-S 4| 0.00| 0.00| 0.00| 0.00| 0.90| 0.00| 96.13 1| 0.00| 0.00| 5.49| 0.00| 0.01| 0.00| 92.26 5| 0.00| 0.00| 0.00| 0.00| 0.46| 0.00| 99.50 2| 45.42| 0.00| 0.00| 0.00| 22.94| 0.00| 28.84 6| 0.00| 37.54| 0.00| 0.00| 0.00| 0.00| 0.00 3| 0.00| 0.00| 0.00| 0.00| 0.30| 0.00| 91.99 7| 0.00| 0.00| 0.00| 0.00| 4.70| 0.00| 0.70 This patch replaces the hard-coded use of cpu0 in cpupower with the current cpu, allowing it to run without a cpu0.
