Hi, All I am reading Linux Kernel's IOAPIC Init routine recently and I found that Linux 2.6.17 Kernel's APIC_init_uniprocessor() routine doesn't use ACPI table's MADT but instead will try to locate MP table. If the MP table is not there, the init routine will simply exit. This is something weird to me, as I take it fro granted that IOAPIC should be initialized using ACPI table now that ACPI is invented partly to take the place of MP table. Can anyone give me some explanations or I was just missing something? Thanks!
