	  This selects the system type of your hardware.  A "generic" kernel
	  will run on any supported IA-64 system.  However, if you configure
	  a kernel for your specific system, it will be faster and smaller.

	  generic		For any supported IA-64 system
	  DIG-compliant		For DIG ("Developer's Interface Guide") compliant systems
	  HP-zx1/sx1000		For HP systems
	  HP-zx1/sx1000+swiotlb	For HP systems with (broken) DMA-constrained devices.
	  SGI-SN2		For SGI Altix systems
	  Ski-simulator		For the HP simulator <http://www.hpl.hp.com/research/linux/ski/>

	help
	  Build a kernel that runs on HP zx1 and sx1000 systems even when they
	  have broken PCI devices which cannot DMA to full 32 bits.  Apart
	  from support for the HP I/O MMU, this includes support for the software
	  I/O TLB, which allows supporting the broken devices at the expense of
	  wasting some kernel memory (about 2MB by default).

config IA64_SGI_SN2
	bool "SGI-SN2"
	help
	  Selecting this option will optimize the kernel for use on sn2 based
	  systems, but the resulting kernel binary will not run on other
	  types of ia64 systems.  If you have an SGI Altix system, it's safe
	  to select this option.  If in doubt, select ia64 generic support
	  instead.

	  An SGI machine can be divided into multiple Single System
	  Images which act independently of each other and have
	  hardware based memory protection from the others.  Enabling
	  this feature will allow for direct communication between SSIs
	  based on a network adapter and DMA messaging.

config FORCE_MAX_ZONEORDER
	int
	default "18"

config SMP
	bool "Symmetric multi-processing support"
	help
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N.  If you have a system with more
	  than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  systems, but will use only one CPU of a multiprocessor system.  If
	  you say Y here, the kernel will run on many, but not all,
	  single processor systems.  On a single processor system, the kernel
	  will run faster if you say N here.

	  See also the <file:Documentation/smp.txt> and the SMP-HOWTO
	  available at <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

config NR_CPUS
	int "Maximum number of CPUs (2-512)"
	range 2 512
	depends on SMP
	default "64"
	help
	  You should set this to the number of CPUs in your system, but
	  keep in mind that a kernel compiled for, e.g., 2 CPUs will boot but
	  only use 2 CPUs on a >2 CPU system.  Setting this to a value larger
	  than 64 will cause the use of a CPU mask array, causing a small
	  performance hit.

config HOTPLUG_CPU
	bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
	depends on SMP && EXPERIMENTAL
	select HOTPLUG
	default n
	---help---
	  Say Y here to experiment with turning CPUs off and on.  CPUs
	  can be controlled through /sys/devices/system/cpu/cpu#.
	  Say N if you want to disable CPU hotplug.

config SCHED_SMT
	bool "SMT scheduler support"
	depends on SMP
	default off
	help
	  Improves the CPU scheduler's decision making when dealing with
	  Intel IA64 chips with MultiThreading at a cost of slightly increased
	  overhead in some places. If unsure say N here.

config PREEMPT
	bool "Preemptible Kernel"
        help
          This option reduces the latency of the kernel when reacting to
          real-time or interactive events by allowing a low priority process to
          be preempted even if it is in kernel mode executing a system call.
          This allows applications to run more reliably even when the system is
          under load.

          Say Y here if you are building a kernel for a desktop, embedded
          or real-time system.  Say N if you are unsure.

	  IA-64 processors can execute IA-32 (X86) instructions.  By
	  saying Y here, the kernel will include IA-32 system call
	  emulation support which makes it possible to transparently
	  run IA-32 Linux binaries on an IA-64 Linux system.
	  If in doubt, say Y.

config PERFMON
	bool "Performance monitor support"
	help
	  Selects whether support for the IA-64 performance monitor hardware
	  is included in the kernel.  This makes some kernel data-structures a
	  little bigger and slows down execution a bit, but it is generally
	  a good idea to turn this on.  If you're unsure, say Y.

config IA64_PALINFO
	tristate "/proc/pal support"
	help
	  If you say Y here, you are able to get PAL (Processor Abstraction
	  Layer) information in /proc/pal.  This contains useful information
	  about the processors in your systems, such as cache and TLB sizes
	  and the PAL firmware version in use.

	  To use this option, you have to ensure that the "/proc file system
	  support" (CONFIG_PROC_FS) is enabled, too.

config PM
	bool "Power Management support"
	depends on !IA64_HP_SIM
	default y
	help
	  "Power Management" means that parts of your computer are shut
	  off or put into a power conserving "sleep" mode if they are not
	  being used.  There are two competing standards for doing this: APM
	  and ACPI.  If you want to use either one, say Y here and then also
	  to the requisite support below.

	  Power Management is most important for battery powered laptop
	  computers; if you have a laptop, check out the Linux Laptop home
	  page on the WWW at <http://www.linux-on-laptops.com/> and the
	  Battery Powered Linux mini-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  Note that, even if you say N here, Linux on the x86 architecture
	  will issue the hlt instruction if nothing is to be done, thereby
	  sending the processor to sleep and saving power.

	  VESA. If you have PCI, say Y, otherwise N.
