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