config SMP
	bool
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, like most personal computers, 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.

	  Note that if you say Y here and choose architecture "586" or
	  "Pentium" under "Processor family", the kernel will not work on 486
	  architectures. Similarly, multiprocessor kernels for the "PPro"
	  architecture may not work on all Pentium based boards.

	  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.

	  The frame buffer device provides an abstraction for the graphics
	  hardware. It represents the frame buffer of some video hardware and
	  allows application software to access the graphics hardware through
	  a well-defined interface, so the software doesn't need to know
	  anything about the low-level (hardware register) stuff.

	  Frame buffer devices work identically across the different
	  architectures supported by Linux and make the implementation of
	  application programs easier and more portable; at this point, an X
	  server exists which uses the frame buffer device exclusively.
	  On several non-X86 architectures, the frame buffer device is the
	  only way to use the graphics hardware.

	  The device is accessed through special device nodes, usually located
	  in the /dev directory, i.e. /dev/fb*.

	  You need an utility program called fbset to make full use of frame
	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
	  and the Framebuffer-HOWTO at
	  <http://www.tahallah.demon.co.uk/programming/prog.html> for more
	  information.

	  Say Y here and to the driver for your graphics board below if you
	  are compiling a kernel for a non-x86 architecture.

	  If you are compiling for the x86 architecture, you can say Y if you
	  want to play with it, but it is not essential. Please note that
	  running graphical applications that directly touch the hardware
	  (e.g. an accelerated X server) and that are not frame buffer
	  device-aware may cause unexpected results. If unsure, say N.

	  I'm told that even without a sound card, you can make your computer
	  say more than an occasional beep, by programming the PC speaker.
	  Kernel patches and supporting utilities to do that are in the pcsp
	  package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

config CROSSCOMPILE
	bool "Are you using a crosscompiler"
	help
	  Say Y here if you are compiling the kernel on a different
	  architecture than the one it is intended to run on.

config REMOTE_DEBUG
	bool "Remote GDB kernel debugging"
	depends on SERIAL=y || AU1000_UART
	help
	  If you say Y here, it will be possible to remotely debug the MIPS
	  kernel using gdb. This enlarges your kernel image disk size by
	  several megabytes and requires a machine with more than 16 MB,
	  better 32 MB RAM to avoid excessive linking time. This is only
	  useful for kernel hackers. If unsure, say N.

config GDB_CONSOLE
	bool "Console output to GDB"
	depends on REMOTE_DEBUG
	help
	  If you are using GDB for remote debugging over a serial port and
	  would like kernel messages to be formatted into GDB $O packets so
	  that GDB prints them as program output, say 'Y'.

config LL_DEBUG
	bool "Low-level debugging"
	depends on SERIAL=y
	help
	  Enable low-level debugging assertion macros in the kernel code.
	  Currently used only by the time services code in the MIPS port.
	  Don't turn this on unless you know what you are doing.

config MAGIC_SYSRQ
	bool "Magic SysRq key"
	help
	  If you say Y here, you will have some control over the system even
	  if the system crashes for example during kernel debugging (e.g., you
	  will be able to flush the buffer cache to disk, reboot the system
	  immediately or dump some status information). This is accomplished
	  by pressing various keys while holding SysRq (Alt+PrintScreen). It
	  also works on a serial console (on PC hardware at least), if you
	  send a BREAK and then within 5 seconds a command keypress. The
	  keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
	  unless you really know what this hack does.

config MIPS_UNCACHED
	bool "Run uncached"
	depends on !SMP
	help
	  If you say Y here there kernel will disable all CPU caches.  This will
	  reduce the system's performance dramatically but can help finding
	  otherwise hard to track bugs.  It can also useful if you're doing
	  hardware debugging with a logic analyzer and need to see all traffic
	  on the bus.

config NR_CPUS
	int "Maximum number of CPUs (2-32)"
	depends on SMP
	default "32"
