Hi Please consider this for inclusion into the testing tree. This patchset introduces cpuidle infrastructure to POWER, prototyping for pSeries, and also does a major refactoring of current x86 idle power management and a cleanup of cpuidle infrastructure. Earlier discussions on the same can be found at: v6 --> http://lkml.org/lkml/2009/9/22/180 v5 --> http://lkml.org/lkml/2009/9/22/26 v4 --> http://lkml.org/lkml/2009/9/1/133 v3 --> http://lkml.org/lkml/2009/8/27/124 v2 --> http://lkml.org/lkml/2009/8/26/233 v1 --> http://lkml.org/lkml/2009/8/19/150 Changes in this version: ----------------------------------------- * Earlier implementation maintained a list of cpuidle devices and the list was traversed to disable and enable the cpuidle devices when switching governors. This list is not necessary and is removed. Now, we get the per cpu structure cpuidle_devices and disable and enable it for each online cpu while switching governors. * Earlier iterations were buggy w.r.t the sysfs interface of the cpuidle. This iteration removes the bug in PATCH 1/7. * In PATCH 7/7, smt_snooze_delay was not being updated whenever it was changed through the sysfs interface. Provide a helper routine to update it. * In PATCH 7/7, the idle loops are renamed to denote the idle states to avoid any confusion. thanks, arun -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
