657 bool "kexec system call (EXPERIMENTAL)"
658 depends on SUPERH32 && MMU
660 kexec is a system call that implements the ability to shutdown your
661 current kernel, and to start another kernel. It is like a reboot
662 but it is independent of the system firmware. And like a reboot
663 you can start any kernel with it, not just Linux.
665 The name comes from the similarity to the exec system call.
667 It is an ongoing process to be certain the hardware in a machine
668 is properly shutdown, so do not be surprised if this code does not
669 initially work for you. It may help to enable device hotplugging
670 support. As of this writing the exact hardware interface is
671 strongly in flux, so no good recommendation can be made.
674 bool "kernel crash dumps (EXPERIMENTAL)"
675 depends on SUPERH32 && BROKEN_ON_SMP
677 Generate crash dump after being started by kexec.
678 This should be normally only set in special crash dump kernels
679 which are loaded in the main kernel with kexec-tools into
680 a specially reserved region and then later executed after
681 a crash by kdump/kexec. The crash dump kernel must be compiled
682 to a memory address not used by the main kernel using

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

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

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