That's decided by HW.
Do you mean even the device is behind the PCIX bridge, it's IRQ is not routed by the APIC on the bridge ?

Eric,
The broadcom nic on hdama is connected behind the 8131. So the IRQ should be routed by the APIC on 8131, right ? But in the current mptable.c it is
/* PCI Ints: Type Polarity Trigger Bus ID PCIDEVNUM|IRQ APIC ID PIN# */ /* On board nics */ smp_write_intsrc(mc, mp_INT, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, bus_8131_1, (0x03<<2)|0, 0x02, 0x13); smp_write_intsrc(mc, mp_INT, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, bus_8131_1, (0x04<<2)|0, 0x02, 0x13);
The IRQ is routed by APIC #2 which is in 8111. Is it correct ? Why is it still working ?
