i386/include apic.h
i386/isa clock.c isa.c sio.c
Log:
Experimental IO APIC code (semi) working.
These changes (+previous) allow the IO APIC to be used in place of the
8259 ICUs.
WARNINGS:
only ISA INTs supported, PCI/EISA cards will fail.
Note that this code routes INTs thru the IO APIC to the 1st CPU
only, no attempt is yet made to dynamically share INT load between
the CPUs.
Serious experimenters can enable this code by changing SMP_SYMIOXXX_NOT
to SMP_SYMIOXXX in i386/include/apic.h
BACK UP YOUR DATA FIRST!
I spammed my "/usr" partition pretty well doing this, but I think it
was the attempt to use a PCI SCSI controller.
