	  This is the Linux Xen port.  Enabling this will allow the
	  kernel to boot in a paravirtualized environment under the
	  Xen hypervisor.

config XEN_512GB
	bool "Limit Xen pv-domain memory to 512GB"
	depends on XEN_PV
	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_PVHVM_GUEST
	bool "Xen PVHVM guest support"

config XEN_DEBUG_FS
	bool "Enable Xen debug and tuning parameters in debugfs"
	depends on XEN && DEBUG_FS
	help
	  Enable statistics output and various tuning options in debugfs.
	  Enabling this option may incur a significant performance overhead.

config XEN_PVH
	bool "Xen PVH guest support"
	depends on XEN && XEN_PVHVM && ACPI
	select PVH
	def_bool n
	help
	  Support for running as a Xen PVH guest.

	  Support running as a Xen Dom0 guest.

config XEN_PV_MSR_SAFE
	bool "Always use safe MSR accesses in PV guests"
	default y
	depends on XEN_PV
	help
	  Use safe (not faulting) MSR access functions even if the MSR access
	  should not fault anyway.
	  The default can be changed by using the "xen_msr_safe" boot parameter.
