clockevents: Define CS_NAME_LEN unconditionally

2013-05-28T07:28:02Z

Unbreak architectures which do not use clockevents, but require to build some of the core timekeeping infrastructure Reported-by: Ingo Molnar Signed-off-by: Thomas Gleixner

clockevents: Implement unbind functionality

2013-05-16T09:09:18Z

Provide a sysfs interface to allow unbinding of clockevent devices. The device is unbound if it is unused or if there is a replacement device available. Unbinding of broadcast devices is not supported as we don't want to foster that nonsense. If no replacement device is available the unbind returns -EBUSY. Unbind is available from the kernel and through sysfs, which is necessary to drop the module refcount.

clockevents: Move the tick_notify() switch case to clockevents_notify()

2013-05-16T09:09:16Z

No need to call another function and have duplicated cases. Signed-off-by: Thomas Gleixner Cc: John Stultz Cc: Magnus Damm Link: http://lkml.kernel.org/r/20130425143436.235746557@linutronix.de Signed-off-by: Thomas Gleixner

timekeeping: Make jiffies_lock internal

2013-03-22T23:20:00Z

tick: Convert broadcast cpu bitmaps to cpumask_var_t

time: Kill xtime_lock, replacing it with jiffies_lock

2012-11-13T19:08:23Z

Now that timekeeping is protected by its own locks, rename the xtime_lock to jifffies_lock to better describe what it protects. CC: Thomas Gleixner CC: Eric Dumazet CC: Richard Cochran Signed-off-by: John Stultz

clockevents: Make minimum delay adjustments configurable

2011-09-08T09:10:56Z

The automatic increase of the min_delta_ns of a clockevents device should be done in the clockevents code as the minimum delay is an attribute of the clockevents device. In addition not all architectures want the automatic adjustment, on a massively virtualized system it can happen that the programming of a clock event fails several times in a row because the virtual cpu has been rescheduled quickly enough. In that case the minimum delay will erroneously be increased with no way back. The new config symbol GENERIC_CLOCKEVENTS_MIN_ADJUST is used to enable the automatic adjustment. The config option is selected only for x86. Signed-off-by: Martin Schwidefsky Cc: john stultz Link: http://lkml.kernel.org/r/20110823133142.494157493@de.ibm.com Signed-off-by: Thomas Gleixner
