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