For all architectures, this just means that you'll see a "Memory Model" choice in your architecture menu. For those that implement DISCONTIGMEM, you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool y" and make your users select DISCONTIGMEM right out of the new choice menu. The only disadvantage might be if you have some specific things that you need in your help option to explain something about DISCONTIGMEM.

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.

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

approximately eight kilobytes to the kernel image.

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
