hmp: added io apic dump state
Added the hmp command to query io apic state, may be usefull after guest crashes to understand IRQ routing in guest. Implementation is only for kvm here. The dump will look like (qemu) info ioapic ioapic id=0x00 sel=0x26 (redir[11]) pin 0 0x0000000000010000 dest=0 vec=0 active-hi edge masked fixed physical pin 1 0x0000000000000031 dest=0 vec=49 active-hi edge fixed physical ... pin 23 0x0000000000010000 dest=0 vec=0 active-hi edge masked fixed physical IRR (none) Remote IRR (none) Signed-off-by: Pavel Butsykin <pbutsykin@virtuozzo.com> Signed-off-by: Denis V.
