2f34a7eaeb X86: Tell the function that sends int messages who to send to instead of figuring it out itself. 2009-04-26 02:09:27 -07:00

88ab4bb257 X86: Make the local APICs register themselves with the IO APIC. 
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.

c5e2cf841d X86: Record the initial APIC ID which identifies an APIC in M5. 
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.

119e127d71 X86: Create the IntDev and IntPin system. 
The IntDev class is a base for anything that supports IntPins. IntPins allow
devices to generically trigger interrupts on a particular pin of an IntDev
device without having to know what the device is or what pin they're attached
to.
