PCI is the name of a bus system, i.e. the way the CPU talks to the other stuff inside your box. If you have PCI, say Y, otherwise N. - -config SH_PCIDMA_NONCOHERENT - bool "Cache and PCI noncoherent" - depends on PCI - default y - help - Enable this option if your platform does not have a CPU cache which - remains coherent with PCI DMA. It is safest to say 'Y', although you - will see better performance if you can say 'N', because the PCI DMA - code will not have to flush the CPU's caches. If you have a PCI host - bridge integrated with your SH CPU, refer carefully to the chip specs - to see if you can say 'N' here. Otherwise, leave it as 'Y'. |
