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.

Say Y to support the Acorn Archimedes.

The Acorn Archimedes was an personal computer based on an 8MHz ARM2

processor, released in 1987. It supported up to 16MB of RAM in
|
|
later models and floppy, harddisc, ethernet etc.

Linux can support the

internal IDE disk and CD-ROM interface, serial and parallel port,

plugged into the wrong socket on the motherboard.

---help---
|
|
Say Y to include the NWFPE floating point emulator in the kernel.
|
|
This is necessary to run most binaries. Linux does not currently
|
|
support floating point hardware so you need to say Y here even if
|
|
your machine has an FPA or floating point co-processor podule.
|
|
|
|
It is also possible to say M to build the emulator as a module
|
|
(nwfpe) or indeed to leave it out altogether. However, unless you
|
|
know what you are doing this can easily render your machine
|
|
unbootable. Saying Y is the safe option.
|
|
|
|
You may say N here if you are going to load the Acorn FPEmulator
|
|
early in the bootup.

|

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.

Say Y here to include the kernel code necessary if you want to run

Acorn RISC OS/Arthur binaries under Linux. This code is still very

experimental; if this sounds frightening, say N and sleep in peace.

You can also say M here to compile this support as a module (which

will be called arthur).

help
|
|
On some architectures (EBSA110 and CATS), there is currently no way
|
|
for the boot loader to pass arguments to the kernel. For these
|
|
architectures, you should supply some command-line options at build
|
|
time by entering them here. As a minimum, you should specify the
|
|
memory size and the root device (e.g., mem=64M root=/dev/nfs).
