-         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.tldp.org/docs.html#howto>
-         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.

-         Say Y here only if you plan to use gdb to debug the kernel.
-         If you don't debug the kernel, you can say N.

-config RUNTIME_DEBUG
-       bool "Enable run-time debugging"
-       depends on DEBUG_KERNEL
-       help
-         If you say Y here, some debugging macros will do run-time checking.
-         If you say N here, those macros will mostly turn to no-ops.  See 
-         include/asm-mips/debug.h for debuging macros.
-         If unsure, say N.

-config MAGIC_SYSRQ
-       bool "Magic SysRq key"
-       depends on DEBUG_KERNEL
-       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

-       depends on DEBUG_KERNEL && !SMP && !SGI_IP27
-       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.
