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

44 depends on EXPERIMENTAL && 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 EXPERIMENTAL && 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
76 Support running unmodified book3s_64 guest kernels in
77 virtual machines on POWER7 and PPC970 processors that have
78 hypervisor mode available to the host.
80 If you say Y here, KVM will use the hardware virtualization
81 facilities of POWER7 (and later) processors, meaning that
82 guest operating systems will run at full hardware speed
83 using supervisor and user modes. However, this also means
84 that KVM is not usable under PowerVM (pHyp), is only usable
85 on POWER7 (or later) processors and PPC970-family processors,
86 and cannot emulate a different processor from the host processor.
90 config KVM_BOOK3S_64_PR
92 depends on KVM_BOOK3S_64 && !KVM_BOOK3S_64_HV
99 bool "KVM support for PowerPC 440 processors"
100 depends on EXPERIMENTAL && 44x
104 Support running unmodified 440 guest kernels in virtual machines on
107 This module provides access to the hardware capabilities through
108 a character device node named /dev/kvm.
112 config KVM_EXIT_TIMING
113 bool "Detailed exit timing"
114 depends on KVM_440 || KVM_E500V2 || KVM_E500MC
116 Calculate elapsed time for every exit/enter cycle. A per-vcpu
117 report is available in debugfs kvm/vm#_vcpu#_timing.
118 The overhead is relatively small, however it is not recommended for
119 production environments.
124 bool "KVM support for PowerPC E500v2 processors"
125 depends on EXPERIMENTAL && E500 && !PPC_E500MC
130 Support running unmodified E500 guest kernels in virtual machines on
131 E500v2 host processors.

134 a character device node named /dev/kvm.
139 bool "KVM support for PowerPC E500MC/E5500 processors"
140 depends on EXPERIMENTAL && PPC_E500MC
146 Support running unmodified E500MC/E5500 (32-bit) guest kernels in
147 virtual machines on E500MC/E5500 host processors.
