* clockevents: introduce force broadcast notifierThomas Gleixner2007-10-141-0/+1
| | | | | | | | | | | | | | | | The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Add a new notifier reason and implement the force broadcast in the clock events layer. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* clockevents: fix resume logicThomas Gleixner2007-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users. Thanks to Nigel Cunningham for tracking down a long standing thinko, which affected the jinxed VAIO.

* [PATCH] clockevents: add core functionalityThomas Gleixner2007-02-161-0/+142
Architectures register their clock event devices, in the clock events core. Users of the clockevents core can get clock event devices for their use. The clockevents core code provides notification mechanisms for various clock related management events. This allows to control the clock event devices without the architectures having to worry about the details of function assignment. This is also a preliminary for high resolution timers and dynamic ticks to allow the core code to control the clock functionality without intrusive changes to the architecture code.
