Hi, 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.
My earlier iterations can be found at: 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: ------------------------------------------ Remove the bug from previous iteration in the routine cpuidle_remove_from_list(), which was causing the kernel to panic on platform supporting multiple sleep states. Add the routine cpuidle_kick_cpus() in POWER, which is needed to kick the cpus out of their idle when changing the idle routines. TODO: ------------------------------------------- Peterz suggested it would be nice to have a sysfs interface through which an idle routine can be forced at runtime. Also, current implementation registers every cpu as a cpuidle_device, but this is an overkill and the registering mechanism should be a systemwide process and not per-cpu. (probably one of the original cpuidle authors can reply to this - Venki, Shaohua Li? ). ppc_md.power_save has been replaced by cpuidle_idle_call only for pseries. So this needs to be done for all POWER platforms so that ppc_md.power_save is completely removed. Any comments on the design is welcome. --arun _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
