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
97 bool "KVM support for PowerPC 440 processors"
98 depends on EXPERIMENTAL && 44x
102 Support running unmodified 440 guest kernels in virtual machines on
105 This module provides access to the hardware capabilities through
106 a character device node named /dev/kvm.
110 config KVM_EXIT_TIMING
111 bool "Detailed exit timing"
112 depends on KVM_440 || KVM_E500V2 || KVM_E500MC
114 Calculate elapsed time for every exit/enter cycle. A per-vcpu
115 report is available in debugfs kvm/vm#_vcpu#_timing.
116 The overhead is relatively small, however it is not recommended for
117 production environments.
122 bool "KVM support for PowerPC E500v2 processors"
123 depends on EXPERIMENTAL && E500 && !PPC_E500MC
127 Support running unmodified E500 guest kernels in virtual machines on
128 E500v2 host processors.
130 This module provides access to the hardware capabilities through
131 a character device node named /dev/kvm.
136 bool "KVM support for PowerPC E500MC/E5500 processors"
137 depends on EXPERIMENTAL && PPC_E500MC
142 Support running unmodified E500MC/E5500 (32-bit) guest kernels in
143 virtual machines on E500MC/E5500 host processors.
