189 Find out whether you have a PCI motherboard. PCI is the name of a
190 bus system, i.e. the way the CPU talks to the other stuff inside
191 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
192 VESA. If you have PCI, say Y, otherwise N.
194 The PCI-HOWTO, available from
195 <http://www.tldp.org/docs.html#howto>, contains valuable
196 information about which PCI hardware does work under Linux and which
199 config SH_PCIDMA_NONCOHERENT
200 bool "Cache and PCI noncoherent"
204 Enable this option if your platform does not have a CPU cache which
205 remains coherent with PCI DMA. It is safest to say 'Y', although you
206 will see better performance if you can say 'N', because the PCI DMA
207 code will not have to flush the CPU's caches. If you have a PCI host
208 bridge integrated with your SH CPU, refer carefully to the chip specs
209 to see if you can say 'N' here. Otherwise, leave it as 'Y'.
