Help¶

Specify the IDT vector to use for the IRQ offload interrupt handler. The default should be fine for most arches, but on systems like MVIC where there is a fixed IRQ-to-vector mapping another value may be needed to avoid collision.

Direct dependencies¶

IRQ_OFFLOAD && X86

(Includes any dependencies from if’s and menus.)

Defaults¶

63 if MVIC && IRQ_OFFLOAD && X86
32 if !MVIC && IRQ_OFFLOAD && X86
