2015-01-03	dev: prevent RTC events firing before startup	Cagdas Dirik
	This change includes edits to MC146818 timer to prevent RTC events firing before startup to comply with SimObject initialization call sequence. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2013-06-03	dev: Clean up MC146818 register (A & B) handling	Andreas Sandberg
	Rewrite reg A & B handling to use the bitunion stuff instead of bit masking. Add better error messages when the kernel tries to enable unsupported stuff.
2012-11-16	sim: have a curTick per eventq	Nilay Vaish
	This patch adds a _curTick variable to an eventq. This variable is updated whenever an event is serviced in function serviceOne(), or all events upto a particular time are processed in function serviceEvents(). This change helps when there are eventqs that do not make use of curTick for scheduling events.
2012-09-19	AddrRange: Transition from Range<T> to AddrRange	Andreas Hansson
	This patch takes the final plunge and transitions from the templated Range class to the more specific AddrRange. In doing so it changes the obvious Range<Addr> to AddrRange, and also bumps the range_map to be AddrRangeMap. In addition to the obvious changes, including the removal of redundant includes, this patch also does some house keeping in preparing for the introduction of address interleaving support in the ranges. The Range class is also stripped of all the functionality that is never used. --HG-- rename : src/base/range.hh => src/base/addr_range.hh rename : src/base/range_map.hh => src/base/addr_range_map.hh
2011-01-07	Replace curTick global variable with accessor functions.	Steve Reinhardt
	This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2010-09-16	devices: undo cset 017baf09599f that added timer drain functions.	Steve Reinhardt
	It's not the right fix for the checkpoint deadlock problem Brad was having, and creates another bug where the system can deadlock on restore. Brad can't reproduce the original bug right now, so we'll wait until it arises again and then try to fix it the right way then.
2010-08-20	devices: Fixed periodic interrupts to work with draining	Brad Beckmann
	Added drain functions to the RTC and 8254 timer so that periodic interrupts stop when the system is draining. This patch is needed to checkpoint in timing mode. Otherwise under certain situations, the event queue will never be completely empty.
2010-04-15	tick: rename Clock namespace to SimClock	Nathan Binkert

2009-08-20	X86: Make the real time clock actually keep track of time.	Gabe Black

2008-10-09	eventq: convert all usage of events to use the new API.	Nathan Binkert
	For now, there is still a single global event queue, but this is necessary for making the steps towards a parallelized m5.
2008-03-25	Devices: Separate out the MC146818 RTC so both Alpha and X86 can use it.	Gabe Black
