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 , 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 "drivers/Kconfig" source "fs/Kconfig" source "arch/sh64/oprofile/Kconfig" menu "Kernel hacking" config MAGIC_SYSRQ bool "Magic SysRq key" help If you say Y here, you will have some control over the system even if the system crashes for example during kernel debugging (e.g., you will be able to flush the buffer cache to disk, reboot the system immediately or dump some status information). This is accomplished by pressing various keys while holding SysRq (Alt+PrintScreen). It also works on a serial console (on PC hardware at least), if you send a BREAK and then within 5 seconds a command keypress. The keys are documented in Documentation/sysrq.txt. Don't say Y unless you really know what this hack does. config EARLY_PRINTK bool "Early SCIF console support" config DEBUG_KERNEL_WITH_GDB_STUB bool "GDB Stub kernel debug" config SH64_PROC_TLB bool "Debug: report TLB fill/purge activity through /proc/tlb" depends on PROC_FS config SH64_PROC_ASIDS bool "Debug: report ASIDs through /proc/asids" depends on PROC_FS config SH64_SR_WATCH bool "Debug: set SR.WATCH to enable hardware watchpoints and trace" config SH_ALPHANUMERIC bool "Enable debug outputs to on-board alphanumeric display" config SH_NO_BSS_INIT bool "Avoid zeroing BSS (to speed-up startup on suitable platforms)" config FRAME_POINTER bool "Compile the kernel with frame pointers" default y if KGDB help If you say Y here the resulting kernel image will be slightly larger and slower, but it will give very useful debugging information. If you don't debug the kernel, you can say N, but we may not be able to solve problems without frame pointers. endmenu source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
