-define KernelPackage/irqbypass/description
-  Various virtualization hardware acceleration techniques allow bypassing or
-  offloading interrupts received from devices around the host kernel.  Posted
-  Interrupts on Intel VT-d systems can allow interrupts to be received
-  directly by a virtual machine.  ARM IRQ Forwarding allows forwarded physical
-  interrupts to be directly deactivated by the guest.  This manager allows
-  interrupt producers and consumers to find each other to enable this sort of
-  bypass.
