[Bug 1400411] Comment bridged from LTC Bugzilla
--- Comment From shrey...@in.ibm.com 2015-01-10 03:01 EDT--- Testing fastsleep - With these patches cpuidle framework picks up fastsleep as one of the idle states. You can observe the cpus entering fastsleep by checking /sys/devices/system/cpu/cpuXX/cpuidle/state2/name. This should show FastSleep. Then while system is idle check /sys/devices/system/cpu/cpuXX/cpuidle/state2/time increment over time This shows the amount of time a particular cpu was in fastsleep. Testing Winkle -- With these patches, offline cpus enter winkle. So test this by offlining and onlining cpus. ppc64_cpu --cores-on=1 ppc64_cpu --cores-on=X where X is the total number of cores available in the machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1400411 Title: Feature: cpuidle: Enable fastsleep and winkle in ubuntu 14.04.02 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1400411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
