If unsure, say N. endmenu source "arch/sh/drivers/Kconfig" endmenu menu "Kernel features" source kernel/Kconfig.hz config KEXEC bool "kexec system call (EXPERIMENTAL)" depends on SUPERH32 && EXPERIMENTAL && MMU help kexec is a system call that implements the ability to shutdown your current kernel, and to start another kernel. 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 SUPERH32 && EXPERIMENTAL && BROKEN_ON_SMP 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 PHYSICAL_START. For more details see Documentation/kdump/kdump.txt config KEXEC_JUMP bool "kexec jump (EXPERIMENTAL)" depends on SUPERH32 && KEXEC && HIBERNATION && EXPERIMENTAL help Jump between original kernel and kexeced kernel and invoke code via KEXEC config PHYSICAL_START hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP) default MEMORY_START ---help--- This gives the physical address where the kernel is loaded and is ordinarily the same as MEMORY_START. Different values are primarily used in the case of kexec on panic where the fail safe kernel needs to run at a different address than the panic-ed kernel. config SECCOMP bool "Enable seccomp to safely compute untrusted bytecode" depends on PROC_FS help This kernel feature is useful for number crunching applications that may need to compute untrusted bytecode during their execution. By using pipes or other transports made available to the process as file descriptors supporting the read/write syscalls, it's possible to isolate those applications in their own address space using seccomp. Once seccomp is enabled via prctl, it cannot be disabled and the task is only allowed to execute a few safe syscalls defined by each seccomp mode. If unsure, say N. config CC_STACKPROTECTOR bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)" depends on SUPERH32 && EXPERIMENTAL help This option turns on the -fstack-protector GCC feature. This feature puts, at the beginning of functions, a canary value on the stack just before the return address, and validates the value just before actually returning. Stack based buffer overflows (that need to overwrite this return address) now also overwrite the canary, which gets detected and the attack is then neutralized via a kernel panic. This feature requires gcc version 4.2 or above. config SMP bool "Symmetric multi-processing support" depends on SYS_SUPPORTS_SMP select USE_GENERIC_SMP_HELPERS ---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_SUBTYPE_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. config HOTPLUG_CPU bool "Support for hot-pluggable CPUs (EXPERIMENTAL)" depends on SMP && HOTPLUG && EXPERIMENTAL help Say Y here to experiment with turning CPUs off and on.
