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

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

768 This allows you to specify the maximum number of CPUs which this
769 kernel will support. The maximum supported value is 32 and the
770 minimum value which makes sense is 2.
772 This is purely to save memory - each supported CPU adds
773 approximately eight kilobytes to the kernel image.
776 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

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

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