Below is a patch from android kernel that maintains a histogram of suspend times. Please review and provide feedback. Statistices on the time spent in suspend are kept in /sys/kernel/debug/sleep_time. Cc: Android Kernel Team <[email protected]> Cc: Colin Cross <[email protected]> Cc: Todd Poynor <[email protected]> Cc: San Mehat <[email protected]> Cc: Benoit Goby <[email protected]> Cc: John Stultz <[email protected]> Cc: Thomas Gleixner <[email protected]> Signed-off-by: Colin Cross <[email protected]> Signed-off-by: Todd Poynor <[email protected]> [[email protected]: Re-formatted suspend time table to better fit expected values. Moved accounting of suspend time into timekeeping core. Removed CONFIG_SUSPEND_TIME flag and made the feature conditional on CONFIG_DEBUG_FS. Changed the file name to sleep_time to better fit terminology in timekeeping core. Changed seq_printf to seq_puts.
