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