245 Find out whether you have a PCI motherboard. PCI is the name of a
246 bus system, i.e. the way the CPU talks to the other stuff inside
247 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
248 VESA. If you have PCI, say Y, otherwise N.
250 The PCI-HOWTO, available from
251 <http://www.tldp.org/docs.html#howto>, contains valuable
252 information about which PCI hardware does work under Linux and which
255 config SH_PCIDMA_NONCOHERENT
256 bool "Cache and PCI noncoherent"
260 Enable this option if your platform does not have a CPU cache which
261 remains coherent with PCI DMA. It is safest to say 'Y', although you
262 will see better performance if you can say 'N', because the PCI DMA
263 code will not have to flush the CPU's caches. If you have a PCI host
264 bridge integrated with your SH CPU, refer carefully to the chip specs
265 to see if you can say 'N' here. Otherwise, leave it as 'Y'.
