[coreboot] ioapic dump tool

[Zoran s]

Hello Ron, Marc (Jones),

I am wondering where IOAPIC code resides (somewhere on SouthBridge) for IVB?

Could you (or anybody) point to me the file where this code exists/lives, so I can inspect it and learn more about IOAPIC itself? This one is implemented usually on PCH, as my best understanding is, and passes MSIs to core LAPICs, via DMI links?

Thank you,
Zoran Stojsavljevic

anybody know of a tool to dump all apics/ioapics from user mode?

I'm having a Very Stupid Problem with a research OS in that we can't
get the apic's and or iopiac's working. I suck at these things. We
can't tell what we've got wrong.I'm hoping a register dump would help
us.
