I call it the \u0027menu\u0027 governor because it\n    considers the full list of idle states before each entry.\n\n    I\u0027ve kept the implementation fairly simple.  It attempts to guess the\n    next residency time and then chooses a state that would meet at least\n    the break-even point between power savings and entry cost.  To this end,\n    it selects the deepest idle state that satisfies the following\n    constraints:\n         1. If the idle time elapsed since bus master activity was detected\n            is below a threshold (currently 20 ms), then limit the selection\n            to C2-type or above.\n         2. Do not choose a state with a break-even residency that exceeds\n            the expected time remaining until the next timer interrupt.\n         3. Do not choose a state with a break-even residency that exceeds\n            the elapsed time between the last pair of break events,\n            excluding timer interrupts.\n\n    This governor has an advantage over \"ladder\" governor because it\n    proactively checks how much time remains until the next timer interrupt\n    using the tick infrastructure.  Also, it handles device interrupt\n    activity more intelligently by not including timer interrupts in break\n    event calculations.  Finally, it doesn\u0027t make policy decisions using the\n    number of state entries, which can have variable residency times (NO_HZ\n    makes these potentially very large), and instead only considers sleep\n    time deltas.\n\n    The menu governor can be selected during runtime using the cpuidle sysfs\n    interface like so:\n    \"echo \"menu\" \u003e /sys/devices/system/cpu/cpuidle/current_governor\"\n\n    Signed-off-by: Adam Belay \u003cabelay@novell.com\u003e\n    Signed-off-by: Len Brown \u003clen.brown@intel.com\u003e\n\ncommit a4bec7e65aa3b7488b879d971651cc99a6c410fe\nAuthor: Adam Belay \u003cabelay@novell.com\u003e\nDate:   Sat Mar 24 03:47:03 2007 -0400\n\n    cpuidle: export time until next timer interrupt using NO_HZ\n\n    Expose information about the time remaining until the next\n    timer interrupt expires by utilizing the dynticks infrastructure.\n    Also modify the main idle loop to allow dynticks to handle\n    non-interrupt break events (e.g. DMA).

Drivers\n      can be generic or particular to specific hardware/platform\n    * allows pluging in multiple policy governors that can take idle state policy\n      decision\n    * The core also has a set of sysfs interfaces with which administrato can know\n      about supported drivers and governors and switch them at run time.\n\n    Signed-off-by: Adam Belay \u003cabelay@novell.com\u003e\n    Signed-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\n    Signed-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\n    Signed-off-by: Len Brown \u003clen.brown@intel.com\u003e\n\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n"
