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