| ---help--- |
| 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. |

| 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. |
| |
| People using multiprocessor machines who say Y here should also say |
| Y to "Enhanced Real Time Clock Support", below. |

| help |
| This allows you to specify the maximum number of CPUs which this |
| kernel will support. The maximum supported value is 32 for 32-bit |
| kernel and 64 for 64-bit kernels; the minimum value which makes |
| sense is 2. |
| |
| This is purely to save memory - each supported CPU adds |
| approximately eight kilobytes to the kernel image. |

| 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. |

| This will result in additional memory usage, so it is not |
