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. If you have PCI, say Y, otherwise N.

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'.
