From 7fece83235a59b15d75d6c8ef2225c24abd4505b Mon Sep 17 00:00:00 2001 From: Naga Chumbalkar Date: Fri, 8 Jul 2011 18:46:42 +0000 Subject: [PATCH] x86, ioapic: Also print Dest field The code in setup_ioapic_irq() determines the Destination Field, so why not also include it in the debug printk output that gets displayed when the boot parameter "apic=debug" is used. Before the change, "dmesg" will show: IOAPIC[0]: Set routing entry (8-1 -> 0x31 -> IRQ 1 Mode:0 Active:0) IOAPIC[0]: Set routing entry (8-2 -> 0x30 -> IRQ 0 Mode:0 Active:0) IOAPIC[0]: Set routing entry (8-3 -> 0x33 -> IRQ 3 Mode:0 Active:0) ... After the change, you will see: IOAPIC[0]: Set routing entry (8-1 -> 0x31 -> IRQ 1 Mode:0 Active:0 Dest:0) IOAPIC[0]: Set routing entry (8-2 -> 0x30 -> IRQ 0 Mode:0 Active:0 Dest:0) IOAPIC[0]: Set routing entry (8-3 -> 0x33 -> IRQ 3 Mode:0 Active:0 Dest:0) ...
