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.

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.
|
|
|
|
The PCI-HOWTO, available from
|
|
<http://www.tldp.org/docs.html#howto>, contains valuable
|
|
information about which PCI hardware does work under Linux and which
|
|
doesn't.

help
|
|
Enable this option if your platform does not have a CPU cache which
|
|
remains coherent with PCI DMA. It is safest to say 'Y', although you
|
|
will see better performance if you can say 'N', because the PCI DMA
|
|
code will not have to flush the CPU's caches. If you have a PCI host
|
|
bridge integrated with your SH CPU, refer carefully to the chip specs
|
|
to see if you can say 'N' here. Otherwise, leave it as 'Y'.
