# This Kconfig describes xen options

config XEN
bool "Xen guest support"
depends on PARAVIRT
select PARAVIRT_CLOCK
select XEN_HAVE_PVMMU
select XEN_HAVE_VPMU
depends on X86_64 || (X86_32 && X86_PAE)
depends on X86_TSC
help
This is the Linux Xen port. Enabling this will allow the
kernel to boot in a paravirtualized environment under the
Xen hypervisor.
config XEN_DOM0
def_bool y
depends on XEN && PCI_XEN && SWIOTLB_XEN
depends on X86_LOCAL_APIC && X86_IO_APIC && ACPI && PCI
config XEN_PVHVM
def_bool y
depends on XEN && PCI && X86_LOCAL_APIC
config XEN_512GB
bool "Limit Xen pv-domain memory to 512GB"
depends on XEN && X86_64
default y
help
Limit paravirtualized user domains to 512GB of RAM.
The Xen tools and crash dump analysis tools might not support
pv-domains with more than 512 GB of RAM. This option controls the
default setting of the kernel to use only up to 512 GB or more.
It is always possible to change the default via specifying the
boot parameter "xen_512gb_limit".
config XEN_SAVE_RESTORE
bool
depends on XEN
select HIBERNATE_CALLBACKS
default y
config XEN_DEBUG_FS
bool "Enable Xen debug and tuning parameters in debugfs"
depends on XEN && DEBUG_FS
default n
help
Enable statistics output and various tuning options in debugfs.
Enabling this option may incur a significant performance overhead.
config XEN_PVH
bool "Support for running as a PVH guest"
depends on X86_64 && XEN && XEN_PVHVM
def_bool n
