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

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

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

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