	  other operating systems inside virtual machines (guests).

	  If you say N, all options in this submenu will be skipped and

	  Support hosting virtualized guest machines. You will also
	  need to select one or more of the processor modules below.

	  This module provides access to the hardware capabilities through
	  a character device node named /dev/kvm.

	  If unsure, say N.

	help
	  Static number of max supported virtual CPUs per VM.

	  If you choose a high number, the vcpu structures will be quite
	  large, so only choose a reasonable number that you expect to
	  actually use.

	  Adds support for a hardware assisted, in-kernel GIC emulation.

	depends on KVM_ARM_VGIC && ARM_ARCH_TIMER
	select HAVE_KVM_IRQCHIP
