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