It is like a reboot but it is independent of the system firmware. And like a reboot you can start any kernel with it, not just Linux. The name comes from the similarity to the exec system call. It is an ongoing process to be certain the hardware in a machine is properly shutdown, so do not be surprised if this code does not initially work for you. It may help to enable device hotplugging support. As of this writing the exact hardware interface is strongly in flux, so no good recommendation can be made. config CRASH_DUMP bool "kernel crash dumps (EXPERIMENTAL)" depends on EXPERIMENTAL help Generate crash dump after being started by kexec. This should be normally only set in special crash dump kernels which are loaded in the main kernel with kexec-tools into a specially reserved region and then later executed after a crash by kdump/kexec. The crash dump kernel must be compiled to a memory address not used by the main kernel using MEMORY_START. For more details see Documentation/kdump/kdump.txt config SMP bool "Symmetric multi-processing support" depends on SYS_SUPPORTS_SMP ---help--- This enables support for systems with more than one CPU. If you have a system with only one CPU, like most personal computers, say N. If you have a system with more than one CPU, say Y. If you say N here, the kernel will run on single and multiprocessor machines, but will use only one CPU of a multiprocessor machine. If you say Y here, the kernel will run on many, but not all, singleprocessor machines. On a singleprocessor machine, the kernel will run faster if you say N here. People using multiprocessor machines who say Y here should also say Y to "Enhanced Real Time Clock Support", below. See also and the SMP-HOWTO available at . If you don't know what to do here, say N. config NR_CPUS int "Maximum number of CPUs (2-32)" range 2 32 depends on SMP default "4" if CPU_SHX3 default "2" help This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 32 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image. source "kernel/Kconfig.preempt" config GUSA def_bool y depends on !SMP && SUPERH32 help This enables support for gUSA (general UserSpace Atomicity). This is the default implementation for both UP and non-ll/sc CPUs, and is used by the libc, amongst others. For additional information, design information can be found in . This should only be disabled for special cases where alternate atomicity implementations exist. config GUSA_RB bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)" depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A) help Enabling this option will allow the kernel to implement some atomic operations using a software implemention of load-locked/ store-conditional (LLSC).

This can be useful if you are on a board which has a small amount of memory. config UBC_WAKEUP bool "Wakeup UBC on startup" depends on CPU_SH4 && !CPU_SH4A help Selecting this option will wakeup the User Break Controller (UBC) on startup. Although the UBC is left in an awake state when the processor comes up, some boot loaders misbehave by putting the UBC to sleep in a power saving state, which causes issues with things like ptrace(). If unsure, say N. config CMDLINE_BOOL bool "Default bootloader kernel arguments" config CMDLINE string "Initial kernel command string" depends on CMDLINE_BOOL default "console=ttySC1,115200" endmenu menu "Bus options" # Even on SuperH devices which don't have an ISA bus, # this variable helps the PCMCIA modules handle # IRQ requesting properly -- Greg Banks. # # Though we're generally not interested in it when # we're not using PCMCIA, so we make it dependent on # PCMCIA outright. -- PFM. config ISA def_bool y depends on PCMCIA && HD6446X_SERIES help Find out whether you have ISA slots on your motherboard. ISA 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 PCI, EISA, MicroChannel (MCA) or VESA. ISA is an older system, now being displaced by PCI; newer boards don't support it. If you have ISA, say Y, otherwise N. config EISA bool ---help--- The Extended Industry Standard Architecture (EISA) bus was developed as an open alternative to the IBM MicroChannel bus. The EISA bus provided some of the features of the IBM MicroChannel bus while maintaining backward compatibility with cards made for the older ISA bus. The EISA bus saw limited use between 1988 and 1995 when it was made obsolete by the PCI bus. Say Y here if you are building a kernel for an EISA-based machine. Otherwise, say N. config MCA bool help MicroChannel Architecture is found in some IBM PS/2 machines and laptops. It is a bus system similar to PCI or ISA. See (and especially the web page given there) before attempting to build an MCA bus kernel. config SBUS bool config SUPERHYWAY tristate "SuperHyway Bus support" depends on CPU_SUBTYPE_SH4_202 config MAPLE bool "Maple Bus support" depends on SH_DREAMCAST help The Maple Bus is SEGA's serial communication bus for peripherals on the Dreamcast. Without this bus support you won't be able to get your Dreamcast keyboard etc to work, so most users probably want to say 'Y' here, unless you are only using the Dreamcast with a serial line terminal or a remote network connection. config CF_ENABLER bool "Compact Flash Enabler support" depends on SOLUTION_ENGINE || SH_SH03 ---help--- Compact Flash is a small, removable mass storage device introduced in 1994 originally as a PCMCIA device. If you say `Y' here, you compile in support for Compact Flash devices directly connected to a SuperH processor. A Compact Flash FAQ is available at .
