10 Say Y here to get to see options for using your Linux host to run
11 other operating systems inside virtual machines (guests).
12 This option alone does not add any kernel code.
14 If you say N, all options in this submenu will be skipped and
21 select PREEMPT_NOTIFIERS
23 select HAVE_KVM_EVENTFD
25 config KVM_BOOK3S_HANDLER
28 config KVM_BOOK3S_32_HANDLER
30 select KVM_BOOK3S_HANDLER

43 tristate "KVM support for PowerPC book3s_32 processors"
44 depends on PPC_BOOK3S_32 && !SMP && !PTE_64BIT
46 select KVM_BOOK3S_32_HANDLER
49 Support running unmodified book3s_32 guest kernels
50 in virtual machines on book3s_32 host processors.
52 This module provides access to the hardware capabilities through
53 a character device node named /dev/kvm.
58 tristate "KVM support for PowerPC book3s_64 processors"
59 depends on PPC_BOOK3S_64
60 select KVM_BOOK3S_64_HANDLER
63 Support running unmodified book3s_64 and book3s_32 guest kernels
64 in virtual machines on book3s_64 host processors.
66 This module provides access to the hardware capabilities through
67 a character device node named /dev/kvm.
71 config KVM_BOOK3S_64_HV
72 bool "KVM support for POWER7 and PPC970 using hypervisor mode in host"
73 depends on KVM_BOOK3S_64
77 Support running unmodified book3s_64 guest kernels in
78 virtual machines on POWER7 and PPC970 processors that have
79 hypervisor mode available to the host.
81 If you say Y here, KVM will use the hardware virtualization
82 facilities of POWER7 (and later) processors, meaning that
83 guest operating systems will run at full hardware speed
84 using supervisor and user modes. However, this also means
85 that KVM is not usable under PowerVM (pHyp), is only usable
86 on POWER7 (or later) processors and PPC970-family processors,
87 and cannot emulate a different processor from the host processor.
91 config KVM_BOOK3S_64_PR
93 depends on KVM_BOOK3S_64 && !KVM_BOOK3S_64_HV
100 bool "KVM support for PowerPC 440 processors"
105 Support running unmodified 440 guest kernels in virtual machines on
108 This module provides access to the hardware capabilities through
109 a character device node named /dev/kvm.
113 config KVM_EXIT_TIMING
114 bool "Detailed exit timing"
115 depends on KVM_440 || KVM_E500V2 || KVM_E500MC
117 Calculate elapsed time for every exit/enter cycle. A per-vcpu
118 report is available in debugfs kvm/vm#_vcpu#_timing.
119 The overhead is relatively small, however it is not recommended for
120 production environments.
125 bool "KVM support for PowerPC E500v2 processors"
126 depends on E500 && !PPC_E500MC
131 Support running unmodified E500 guest kernels in virtual machines on
132 E500v2 host processors.
134 This module provides access to the hardware capabilities through
135 a character device node named /dev/kvm.
140 bool "KVM support for PowerPC E500MC/E5500/E6500 processors"
141 depends on PPC_E500MC
147 Support running unmodified E500MC/E5500/E6500 guest kernels in
148 virtual machines on E500MC/E5500/E6500 host processors.
150 This module provides access to the hardware capabilities through
151 a character device node named /dev/kvm.
156 bool "KVM in-kernel MPIC emulation"
157 depends on KVM && E500
158 select HAVE_KVM_IRQCHIP
159 select HAVE_KVM_IRQ_ROUTING
162 Enable support for emulating MPIC devices inside the
163 host kernel, rather than relying on userspace to emulate.
164 Currently, support is limited to certain versions of
165 Freescale's MPIC implementation.
168 bool "KVM in-kernel XICS emulation"
169 depends on KVM_BOOK3S_64 && !KVM_MPIC
171 Include support for the XICS (eXternal Interrupt Controller
172 Specification) interrupt controller architecture used on
173 IBM POWER (pSeries) servers.
