Emulate an Intel ioapic programmable interrupt controller.
Synopsis:
vdev ioapic options
Options:
- hostvector
vector
- Associate the first guest interrupt of the I/O APIC with the host interrupt
number specified by vector; associate the second guest
interrupt with vector +1, etc.
- If a guest interrupt is marked as a pass-through target and no host vector
is explicitly provided, this association provides the host interrupt vector
number to use for the guest interrupt.
- intr apic
- Downstream interrupt to raise.
- loc
addr
- Base address of the device registers.
- name
name
- Name to use for upstream interrupts referencing this PIC.
For a list of options available to all vdevs, see “Common vdev options” at the beginning of this
chapter.
Description:
x86 only. The ioapic virtual device emulates an Intel I/O APIC
programmable interrupt controller.
