bool "Mappi-I"

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.

The M3T-M32700UT is an evaluation board based on uT-Engine

specification. This board has an M32700 (Chaos) evaluation chip.

You can say Y for SMP, because the M32700 is a single chip

multiprocessor.

help

The OAKS32R is a tiny, inexpensive evaluation board.

Please note that if you say Y here and choose chip "M32102",

say N for MMU and select a no-MMU version kernel, otherwise

a kernel with MMU support will not work, because the M32102

is a microcontroller for embedded systems and it has no MMU.

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.

Say Y here if you are building a kernel for a desktop, embedded

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

config SMP

bool "Symmetric multi-processing support"

select USE_GENERIC_SMP_HELPERS

---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.

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 the SMP-HOWTO available at

<http://www.linuxdoc.org/docs.html#howto>.

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

help

This allows you to specify the maximum number of CPUs which this

kernel will support. The maximum supported value is 32 and 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.

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.

default PCI_GOANY

config PCI_GOBIOS

bool "BIOS"

---help---

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

determine their configuration. However, some old PCI motherboards

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

"Any".
