menuconfig VIRTUALIZATION
bool "Virtualization"
---help---
Say Y here to get to see options for using your Linux host to run
other operating systems inside virtual machines (guests).
This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and
disabled.

bool "Kernel-based Virtual Machine (KVM) support"
select PREEMPT_NOTIFIERS

select KVM_MMIO
select KVM_ARM_HOST
depends on ARM_VIRT_EXT && ARM_LPAE
---help---
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.
config KVM_ARM_HOST
bool "KVM host support for ARM cpus."
depends on KVM
depends on MMU
select MMU_NOTIFIER
---help---
Provides host support for ARM processors.
config KVM_ARM_MAX_VCPUS
int "Number maximum supported virtual CPUs per VM" if KVM_ARM_HOST
default 4 if KVM_ARM_HOST
default 0
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.
config KVM_ARM_VGIC
bool "KVM support for Virtual GIC"
depends on KVM_ARM_HOST && OF
select HAVE_KVM_IRQCHIP
default y
---help---
Adds support for a hardware assisted, in-kernel GIC emulation.
config KVM_ARM_TIMER
bool "KVM support for Architected Timers"
depends on KVM_ARM_VGIC && ARM_ARCH_TIMER
select HAVE_KVM_IRQCHIP
default y
---help---
Adds support for the Architected Timers in virtual machines
