Here are some common options that can be applied to many types of vdevs.

These general options are described below.However, if an option is also described in its stand-alone vdev reference documentation, limited reference is made to its stand-alone description.

hostvector vector_number

Applies to PIC virtual devices only.This option is used to configure the relative host vector number in the first line of the current virtual device configuration context.This number is used by InterruptAttach() and InterruptAttachEvent() (see the QNX SDP C Library Reference).The PIC input line is followed by a sequentially assigned host vector number.

This option is only required when PIC guest interrupts are marked as passthrough.If no hostvector is specified, it defaults to the hostvector number of the previous PIC device plus the line number of the previous device.If this is the first PIC specified, its hostvector defaults to 0 (zero).

intr guest_intr

The guest interrupt of the current virtual device is set in guest_intr.Consists of two parts separated by a colon (intr gic:40).

For PCI devices that use interrupts, if you do not set the number of guest_intr, this number will be automatically assigned.For non-PCI devices (such as MMIO devices) ࿰
