634 bool "kexec system call (EXPERIMENTAL)"
635 depends on SUPERH32 && MMU
637 kexec is a system call that implements the ability to shutdown your
638 current kernel, and to start another kernel. It is like a reboot
639 but it is independent of the system firmware. And like a reboot
640 you can start any kernel with it, not just Linux.
642 The name comes from the similarity to the exec system call.
644 It is an ongoing process to be certain the hardware in a machine
645 is properly shutdown, so do not be surprised if this code does not
646 initially work for you. It may help to enable device hotplugging
647 support. As of this writing the exact hardware interface is
648 strongly in flux, so no good recommendation can be made.
651 bool "kernel crash dumps (EXPERIMENTAL)"
652 depends on SUPERH32 && BROKEN_ON_SMP
654 Generate crash dump after being started by kexec.
655 This should be normally only set in special crash dump kernels
656 which are loaded in the main kernel with kexec-tools into
657 a specially reserved region and then later executed after
658 a crash by kdump/kexec. The crash dump kernel must be compiled
659 to a memory address not used by the main kernel using

671 config PHYSICAL_START
672 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
675 This gives the physical address where the kernel is loaded
676 and is ordinarily the same as MEMORY_START.
678 Different values are primarily used in the case of kexec on panic
679 where the fail safe kernel needs to run at a different address
680 than the panic-ed kernel.
683 bool "Enable seccomp to safely compute untrusted bytecode"
686 This kernel feature is useful for number crunching applications
687 that may need to compute untrusted bytecode during their
688 execution. By using pipes or other transports made available to
689 the process as file descriptors supporting the read/write
690 syscalls, it's possible to isolate those applications in
691 their own address space using seccomp. Once seccomp is
692 enabled via prctl, it cannot be disabled and the task is only
693 allowed to execute a few safe syscalls defined by each seccomp
698 config CC_STACKPROTECTOR
699 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
702 This option turns on the -fstack-protector GCC feature. This
703 feature puts, at the beginning of functions, a canary value on
704 the stack just before the return address, and validates
705 the value just before actually returning. Stack based buffer
706 overflows (that need to overwrite this return address) now also
707 overwrite the canary, which gets detected and the attack is then
708 neutralized via a kernel panic.
710 This feature requires gcc version 4.2 or above.
713 bool "Symmetric multi-processing support"
714 depends on SYS_SUPPORTS_SMP
715 select USE_GENERIC_SMP_HELPERS
717 This enables support for systems with more than one CPU. If you have
718 a system with only one CPU, like most personal computers, say N. If
719 you have a system with more than one CPU, say Y.
721 If you say N here, the kernel will run on single and multiprocessor
722 machines, but will use only one CPU of a multiprocessor machine. If
723 you say Y here, the kernel will run on many, but not all,
724 singleprocessor machines. On a singleprocessor machine, the kernel
725 will run faster if you say N here.
727 People using multiprocessor machines who say Y here should also say
728 Y to "Enhanced Real Time Clock Support", below.
730 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
731 available at <http://www.tldp.org/docs.html#howto>.
733 If you don't know what to do here, say N.
736 int "Maximum number of CPUs (2-32)"
739 default "4" if CPU_SUBTYPE_SHX3
742 This allows you to specify the maximum number of CPUs which this
743 kernel will support. The maximum supported value is 32 and the
744 minimum value which makes sense is 2.
746 This is purely to save memory - each supported CPU adds
747 approximately eight kilobytes to the kernel image.
750 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

754 can be controlled through /sys/devices/system/cpu.

762 This enables support for gUSA (general UserSpace Atomicity).
763 This is the default implementation for both UP and non-ll/sc
764 CPUs, and is used by the libc, amongst others.
766 For additional information, design information can be found
767 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
769 This should only be disabled for special cases where alternate
770 atomicity implementations exist.
773 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
774 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
776 Enabling this option will allow the kernel to implement some
777 atomic operations using a software implementation of load-locked/
778 store-conditional (LLSC). On machines which do not have hardware
779 LLSC, this should be more efficient than the other alternative of
780 disabling interrupts around the atomic sequence.
