| help |
| The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping. |
| You can operate a Linux system on this board by using an M32R |
| softmacro core, which is a fully-synthesizable functional model |
| described in Verilog-HDL. |
| |
| The Mappi-I board was the first platform, which had been used |
| to port and develop a Linux system for the M32R processor. |
| Currently, the Mappi-II, an heir to the Mappi-I, is available. |

| 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. |

| or real-time system. Say N if you are unsure. |

| 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. The "Advanced Power |
| Management" code will be disabled if you say Y here. |

| ---help--- |
| On PCI systems, the BIOS can be used to detect the PCI devices and |

| have BIOS bugs and may crash if this is done. Also, some embedded |
| PCI-based systems don't have any BIOS at all. Linux can also try to |
| detect the PCI hardware directly without using the BIOS. |
| |
| With this option, you can specify how Linux should detect the PCI |
| devices. If you choose "BIOS", the BIOS will be used, if you choose |
| "Direct", the BIOS won't be used, and if you choose "Any", the |
| kernel will try the direct access method and falls back to the BIOS |
| if that doesn't work. If unsure, go with the default, which is |
