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.
config SH_PCIDMA_NONCOHERENT
bool "Cache and PCI noncoherent"
depends on PCI
default y
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'.
