PCI is the name of a bus system, i.e. the way the CPU talks to the other stuff inside your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or VESA. If you have PCI, say Y, otherwise N. The PCI-HOWTO, available from <http://www.tldp.org/docs.html#howto>, contains valuable information about which PCI hardware does work under Linux and which doesn't. 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'. source "drivers/pci/Kconfig" source "drivers/pcmcia/Kconfig" source "drivers/pci/hotplug/Kconfig" endmenu menu "Executable file formats" source "fs/Kconfig.binfmt" endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "arch/sh64/oprofile/Kconfig" source "arch/sh64/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig" # # Use the generic interrupt handling code in kernel/irq/: # config GENERIC_HARDIRQS bool default y config GENERIC_IRQ_PROBE bool default y
