+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.
