clockevents: Add generic timer broadcast function

2013-01-31T21:15:36Z

Currently, the timer broadcast mechanism is defined by a function pointer on struct clock_event_device. As the fundamental mechanism for broadcast is architecture-specific, this means that clock_event_device drivers cannot be shared across multiple architectures. This patch adds an (optional) architecture-specific function for timer tick broadcast, allowing drivers which may require broadcast functionality to be shared across multiple architectures.

timekeeping: Switch HAS_PERSISTENT_CLOCK to ALWAYS_USE_PERSISTENT_CLOCK

2013-01-29T22:40:12Z

Jason pointed out the HAS_PERSISTENT_CLOCK name isn't quite accurate for the config, as some systems may have the persistent_clock in some cases, but not always. So change the config name to the more clear ALWAYS_USE_PERSISTENT_CLOCK. Signed-off-by: John Stultz

timekeeping: Add CONFIG_HAS_PERSISTENT_CLOCK option

2013-01-16T02:16:08Z

Make the persistent clock check a kernel config option, so that some platform can explicitely select it, also make CONFIG_RTC_HCTOSYS and RTC_SYSTOHC depend on its non-existence, which could prevent the persistent clock and RTC code from doing similar thing twice during system's init/suspend/resume phases. If the CONFIG_HAS_PERSISTENT_CLOCK=n, then no change happens for kernel which still does the persistent clock check in timekeeping_init().

time: Introduce new GENERIC_TIME_VSYSCALL

2012-09-24T16:38:08Z

Now that we moved everyone over to GENERIC_TIME_VSYSCALL_OLD, introduce the new declaration and config option for the new update_vsyscall method.

timers: Fixup the Kconfig consolidation fallout

2012-05-21T21:43:46Z

Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

timers: Provide generic Kconfig switches

tick: Document TICK_ONESHOT config option

2012-03-31T10:45:43Z

This option has been selected from arch code as it was assumed that it's necessary to support oneshot mode clockevent devices. But it's just a core internal helper to compile tick-oneshot.c if NOHZ or HIG_RES_TIMERS are selected. Reported-by: Russell King Signed-off-by: Thomas Gleixner

clockevents: drop unknown Kconfig symbol GENERIC_CLOCKEVENTS_MIGR

There's no Kconfig symbol GENERIC_CLOCKEVENTS_MIGR, so the check for it will always fail. Signed-off-by: Paul Bolle Signed-off-by: Jiri Kosina
