- config KEXEC
- bool "kexec system call (EXPERIMENTAL)"
- depends on SUPERH32 && MMU
- select KEXEC_CORE
- 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. 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 && 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
- 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 SMP
- bool "Symmetric multi-processing support"
- depends on SYS_SUPPORTS_SMP
- ---help---
- This enables support for systems with more than one CPU. If you have
- a system with only one CPU, say N. If you have a system with more
- than one CPU, say Y.
- If you say N here, the kernel will run on uni- 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,
- uniprocessor machines. On a uniprocessor 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 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
- available at <http://www.tldp.org/docs.html#howto>.
- 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
- help
- Say Y here to experiment with turning CPUs off and on. CPUs
- can be controlled through /sys/devices/system/cpu.
- source "kernel/Kconfig.preempt"
- config GUSA
- def_bool y
- depends on !SMP && SUPERH32
- help
- This enables support for gUSA (general UserSpace Atomicity).
- This is the default implementation for both UP and non-ll/sc
- CPUs, and is used by the libc, amongst others.
- For additional information, design information can be found
- in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
- This should only be disabled for special cases where alternate
- atomicity implementations exist.
- config GUSA_RB
- bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
- depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
- help
- Enabling this option will allow the kernel to implement some
- atomic operations using a software implementation of load-locked/
- store-conditional (LLSC). On machines which do not have hardware
- LLSC, this should be more efficient than the other alternative of
- disabling interrupts around the atomic sequence.
- config HW_PERF_EVENTS
- bool "Enable hardware performance counter support for perf events"
- depends on PERF_EVENTS && CPU_HAS_PMU
