config SPARC

	bool

	default y

	select HAVE_IDE

	select HAVE_LMB

	help

	  SPARC is a family of RISC microprocessors designed and marketed by

	  Sun Microsystems, incorporated.  This port covers the newer 64-bit

	  UltraSPARC.  The UltraLinux project maintains both the SPARC32 and

	  SPARC64 ports; its web page is available at

	  <http://www.ultralinux.org/>.

config GENERIC_TIME

	bool

	help

	  This lets you select the page size of the kernel.

	  8KB and 64KB work quite well, since Sparc ELF sections

	  8KB and 64KB work quite well, since SPARC ELF sections

	  provide for up to 64KB alignment.

	  Therefore, 512KB and 4MB are for expert hackers only.

	bool "Support for hot-pluggable CPUs"

	depends on SMP

	select HOTPLUG

	---help---

	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 SMP

	bool "Symmetric multi-processing support"

	---help---

	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

	  machines, but will use only one CPU of a multiprocessor machine. If

	  you say Y here, the kernel will run on many, but not all,

	  singleprocessor machines. On a singleprocessor machine, the kernel

	  will run faster if you say N here.

	  People using multiprocessor machines who say Y here should also say

	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power

	  Management" code will be disabled if you say Y here.

	  See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO

	  available at <http://www.tldp.org/docs.html#howto>.

	  you say Y here, the kernel will run on single-processor machines.

	  On a single-processor machine, the kernel will run faster if you say

	  N here.

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

config ISA

	bool

	help

	  Find out whether you have ISA slots on your motherboard.  ISA is the

	  name of a bus system, i.e. the way the CPU talks to the other stuff

	  inside your box.  Other bus systems are PCI, EISA, MicroChannel

	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;

	  newer boards don't support it.  If you have ISA, say Y, otherwise N.

config ISAPNP

	bool

	help

	  Say Y here if you would like support for ISA Plug and Play devices.

	  Some information is in <file:Documentation/isapnp.txt>.

	  To compile this driver as a module, choose M here: the

	  module will be called isapnp.

	  If unsure, say Y.

config EISA

	bool

	---help---

	  The Extended Industry Standard Architecture (EISA) bus was

	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel

	  bus while maintaining backward compatibility with cards made for

	  the older ISA bus.  The EISA bus saw limited use between 1988 and

	  1995 when it was made obsolete by the PCI bus.

	  Say Y here if you are building a kernel for an EISA-based machine.

	  Otherwise, say N.

config MCA

	bool

	help

	  MicroChannel Architecture is found in some IBM PS/2 machines and

	  laptops.  It is a bus system similar to PCI or ISA. See

	  <file:Documentation/mca.txt> (and especially the web page given

	  there) before attempting to build an MCA bus kernel.

config PCMCIA

	tristate

	---help---

	help

	  Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

	  computer.  These are credit-card size devices such as network cards,

	  modems or hard drives often used with laptops computers.  There are

	bool "PCI support"

	select ARCH_SUPPORTS_MSI

	help

	  Find out whether you have a PCI motherboard. PCI is the name of a

	  bus system, i.e. the way the CPU talks to the other stuff inside

	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or

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

	  Find out whether your system includes a PCI bus. PCI is the name of

	  a bus system, i.e. the way the CPU talks to the other stuff inside

	  your box.  If you say Y here, the kernel will include drivers and

	  infrastructure code to support PCI bus devices.

config PCI_DOMAINS

	def_bool PCI

source "fs/Kconfig.binfmt"

config SPARC32_COMPAT

	bool "Kernel support for Linux/Sparc 32bit binary compatibility"

	bool "Kernel support for 32-bit SPARC binary compatibility"

	help

	  This allows you to run 32-bit binaries on your Ultra.

	  This allows you to run 32-bit binaries on your 64-bit SPARC system.

	  Everybody wants this; say Y.

config COMPAT

	default y

	help

	  SMT scheduler support improves the CPU scheduler's decision making

	  when dealing with UltraSPARC cpus at a cost of slightly increased

	  overhead in some places. If unsure say N here.
