2010-08-20devices: Fixed periodic interrupts to work with drainingBrad 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.
2010-08-17bus: clean up default responder code.Steve Reinhardt
Clean up some minor things left over from the default responder change in rev 9af6fb59752f. Mostly renaming the 'responder_set' param to 'use_default_range' to actually reflect what it does... old name wasn't that descriptive in the first place, but now it really doesn't make sense at all. Also got rid of the bogus obsolete assignment to 'bus.responder' which used to be a parameter but now is interpreted as an implicit child assignment, and which was giving me problems in the config restructuring to come. (A good argument for not allowing implicit child assignments, IMO, but that's water under the bridge, I'm afraid.) Also moved the Bus constructor to the .cc file since that's where it should have been all along.

2009-04-26X86: Implement lowest priority interrupts more correctly.Gabe Black
Lowest priority interrupts are now delivered based on a rotating offset into the list of potential recipients. There could be parasitic cases were a processor gets picked on and ends up at that rotating offset all the time, but it's much more likely that the group will stay consistent and the pain will be distributed evenly.

figuring it out itself.
2009-04-26X86: Make the local APICs register themselves with the IO APIC.Gabe Black
This is a hack so that the IO APIC can figure out information about the local APICs. The local APICs still have no way to find out about each other. Ideally, when the local APICs update state that's relevant to somebody else, they'd send an update to everyone. Without being able to do a broadcast, that would still require knowing who else there is to notify. Other broadcasts are implemented using assumptions that may not always be true.
2009-04-26X86: Record the initial APIC ID which identifies an APIC in M5.Gabe Black
The ID as exposed to software can be changed. Tracking those changes in M5 would be cumbersome, especially since there's no guarantee the IDs will remain unique.

interrupt assignment.
2009-04-22i8254xGBe: major style overhaul.Steve Reinhardt
Moved DescCache template functions from .hh to .cc file. Also fixed lots of line-wrapping problems, and some irregular indentation.
2008-07-16mem: use single BadAddr responder per system.Steve Reinhardt
Previously there was one per bus, which caused some coherence problems when more than one decided to respond. Now there is just one on the main memory bus. The default bus responder on all other buses is now the downstream cache's cpu_side port. Caches no longer need to do address range filtering; instead, we just have a simple flag to prevent snoops from propagating to the I/O bus.
