I thought ACPI was a superset of _MP_. I have a friend who claims not:
"0xffffffffffff0390 A P I C Local APIC Address 0xfee00000, flags 0x00000001 type 0, length 8 ACPI Processor ID 1 APIC ID 0 Flags 0x00000001 type 0, length 8 ACPI Processor ID 2 APIC ID 1 Flags 0x00000001 type 0, length 8 ACPI Processor ID 3 APIC ID 2 Flags 0x00000001 type 0, length 8 ACPI Processor ID 4 APIC ID 3 Flags 0x00000001 type 1, length 12 I/O APIC ID 4 I/O APIC Address 0xfec00000 Global System Interrupt Base 0x00000000 type 1, length 12 I/O APIC ID 5 I/O APIC Address 0xfe6fe000 Global System Interrupt Base 0x00000018 type 1, length 12 I/O APIC ID 6 I/O APIC Address 0xfe6ff000 Global System Interrupt Base 0x0000001c type 2, length 10 IRQ 0 Global System Interrupt 0x00000002 Flags 0x0000 type 2, length 10 IRQ 0 Global System Interrupt 0x00000002 Flags 0x0000
there's not enough info there to actually do anything."
Is he missing something? Is this old information? I'd like to know.
