Subject: [patch 33/46] clockevents: add core functionality
Date: Tue, 23 Jan 2007 22:01:29 -0000	[thread overview]
Message-ID: <20070123211208.065969000@localhost.localdomain> (raw)
In-Reply-To: <20070123211159.178138000@localhost.localdomain>

[-- Attachment #1: clockevents-core.patch --]
[-- Type: text/plain, Size: 17417 bytes --]

From: Thomas Gleixner <tglx@linutronix.de>

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.
