I think this is used all over the place.
No, it isn't. This is only about hot pluggable I/O-APICs, which is a pointless business on x86 (as the rest of the infrastructure to support this is missing). At most IA64 ever had a use for this, which is why some time ago I actually submitted the patch to allow this to be a module on x86 (so one could keep building it, but wouldn't have it around all the time).
Furthermore, I guess even on IA64 it was dead code (maybe just following some never implemented spec), because up until that very patch the driver didn't even have its ID table right, i.e. would never have got bound to a matching device by the PCI core.
Ok, thanks for weighing in. I scanned sysfs and dmesg real quick to see if I could find matching strings and found something similar. Must've been the regular ioapic. -Jeff -- Jeff Mahoney SUSE Labs
