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

41 tristate "KVM support for PowerPC book3s_32 processors"
42 depends on EXPERIMENTAL && PPC_BOOK3S_32 && !SMP && !PTE_64BIT
44 select KVM_BOOK3S_32_HANDLER
47 Support running unmodified book3s_32 guest kernels
48 in virtual machines on book3s_32 host processors.
50 This module provides access to the hardware capabilities through
51 a character device node named /dev/kvm.
56 tristate "KVM support for PowerPC book3s_64 processors"
57 depends on EXPERIMENTAL && PPC_BOOK3S_64
58 select KVM_BOOK3S_64_HANDLER
61 Support running unmodified book3s_64 and book3s_32 guest kernels
62 in virtual machines on book3s_64 host processors.
64 This module provides access to the hardware capabilities through
65 a character device node named /dev/kvm.
69 config KVM_BOOK3S_64_HV
70 bool "KVM support for POWER7 and PPC970 using hypervisor mode in host"
71 depends on KVM_BOOK3S_64
74 Support running unmodified book3s_64 guest kernels in
75 virtual machines on POWER7 and PPC970 processors that have
76 hypervisor mode available to the host.
78 If you say Y here, KVM will use the hardware virtualization
79 facilities of POWER7 (and later) processors, meaning that
80 guest operating systems will run at full hardware speed
81 using supervisor and user modes. However, this also means
82 that KVM is not usable under PowerVM (pHyp), is only usable
83 on POWER7 (or later) processors and PPC970-family processors,
84 and cannot emulate a different processor from the host processor.
88 config KVM_BOOK3S_64_PR
90 depends on KVM_BOOK3S_64 && !KVM_BOOK3S_64_HV
94 bool "KVM support for PowerPC 440 processors"
95 depends on EXPERIMENTAL && 44x
99 Support running unmodified 440 guest kernels in virtual machines on
102 This module provides access to the hardware capabilities through
103 a character device node named /dev/kvm.
107 config KVM_EXIT_TIMING
108 bool "Detailed exit timing"
109 depends on KVM_440 || KVM_E500
111 Calculate elapsed time for every exit/enter cycle. A per-vcpu
112 report is available in debugfs kvm/vm#_vcpu#_timing.
113 The overhead is relatively small, however it is not recommended for
114 production environments.
119 bool "KVM support for PowerPC E500 processors"
120 depends on EXPERIMENTAL && E500
124 Support running unmodified E500 guest kernels in virtual machines on
125 E500 host processors.
127 This module provides access to the hardware capabilities through
128 a character device node named /dev/kvm.
