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