6 bool "Xen guest support"
9 depends on X86_64 || (X86_32 && X86_PAE)
10 depends on X86_LOCAL_APIC && X86_TSC
12 This is the Linux Xen port. Enabling this will allow the
13 kernel to boot in a paravirtualized environment under the
17 bool "Xen PV guest support"
23 Support running as a Xen PV guest.
27 depends on XEN_PV && SMP
30 bool "Xen PV Dom0 support"
32 depends on XEN_PV && PCI_XEN && SWIOTLB_XEN
33 depends on X86_IO_APIC && ACPI && PCI
35 Support running as a Xen PV Dom0 guest.
38 bool "Xen PVHVM guest support"
40 depends on XEN && PCI && X86_LOCAL_APIC
42 Support running as a Xen PVHVM guest.
46 depends on XEN_PVHVM && SMP
49 bool "Limit Xen pv-domain memory to 512GB"
50 depends on XEN_PV && X86_64
53 Limit paravirtualized user domains to 512GB of RAM.
55 The Xen tools and crash dump analysis tools might not support
56 pv-domains with more than 512 GB of RAM. This option controls the
57 default setting of the kernel to use only up to 512 GB or more.
58 It is always possible to change the default via specifying the
59 boot parameter "xen_512gb_limit".
61 config XEN_SAVE_RESTORE
64 select HIBERNATE_CALLBACKS
68 bool "Enable Xen debug and tuning parameters in debugfs"
69 depends on XEN && DEBUG_FS
72 Enable statistics output and various tuning options in debugfs.
73 Enabling this option may incur a significant performance overhead.
76 bool "Support for running as a PVH guest"
77 depends on XEN && XEN_PVHVM && ACPI
