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.

This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
If unsure, say N.

depends on KVM_BOOK3S_64
---help---
Support running unmodified book3s_64 guest kernels in
virtual machines on POWER7 processors that have hypervisor
mode available to the host.
If you say Y here, KVM will use the hardware virtualization
facilities of POWER7 (and later) processors, meaning that
guest operating systems will run at full hardware speed
using supervisor and user modes. However, this also means
that KVM is not usable under PowerVM (pHyp), is only usable
on POWER7 (or later) processors, and can only emulate
POWER5+, POWER6 and POWER7 processors.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
If unsure, say N.

bool "Detailed exit timing"
depends on KVM_440 || KVM_E500
---help---
Calculate elapsed time for every exit/enter cycle. A per-vcpu
report is available in debugfs kvm/vm#_vcpu#_timing.
The overhead is relatively small, however it is not recommended for
production environments.
If unsure, say N.
