This patchset updates devfreq core to add support for devices which can idle. When device idleness is detected perhaps through runtime-pm, need some mechanism to suspend devfreq load monitoring and resume when device is back online.
patch 1 introduce core design changes - per device work, decouple delayed work from core and event based interaction. patch 2 add devfreq suspend and resume apis. patch 3 current frequency bug fix and add new sysfs attribute for governor predicted next target frequency. The existing devfreq apis are kept intact. Two new apis devfreq_suspend_device() and devfreq_resume_device() are added to support suspend/resume of device devfreq. -- Rajagopal Venkat (3): devfreq: core updates to support devices which can idle devfreq: Add suspend and resume apis devfreq: Add current freq callback in device profile Documentation/ABI/testing/sysfs-class-devfreq | 7 + drivers/devfreq/devfreq.c | 412 +++++++++++--------------- drivers/devfreq/governor.h | 11 + drivers/devfreq/governor_performance.c | 16 +- drivers/devfreq/governor_powersave.c | 16 +- drivers/devfreq/governor_simpleondemand.c | 42 +++ drivers/devfreq/governor_userspace.c | 23 +- include/linux/devfreq.h | 46 ++- 8 files changed, 291 insertions(+), 282 deletions(-) -- 1.7.11.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
