Thus, the apic device is not strictly an SMP option, 31# but it is a prerequisite for SMP. 32# 33# Notes: 34# 35# By default, mixed mode is used to route IRQ0 from the AT timer via 36# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 37# This can be disabled via the NO_MIXED_MODE option. In that case, 38# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 39# motherboards hook IRQ0 up to the first I/O APIC even though their 40# MP table or MADT may claim to do so. That is why mixed mode is 41# enabled by default. 42# |
