and consumer electronics; it was also used in the Sega Dreamcast
|
|
gaming console. The SuperH port has a home page at

This adds the cpufreq driver for SuperH. Any CPU that supports
|
|
clock rate rounding through the clock framework can use this
|
|
driver. While it will make the kernel slightly larger, this is
|
|
harmless for CPUs that don't support rate rounding. The driver
|
|
will also generate a notice in the boot log before disabling
|
|
itself if the CPU in question is not capable of rate rounding.
|
|
|
|
For details, take a look at <file:Documentation/cpu-freq>.

If unsure, say N.

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. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is
|
|
strongly in flux, so no good recommendation can be made.

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
|
|
MEMORY_START.

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.

---help---
|
|
This enables support for systems with more than one CPU. If you have
|
|
a system with only one CPU, like most personal computers, say N. If
|
|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single 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,
|
|
singleprocessor machines. On a singleprocessor 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.

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.

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.

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.

depends on EXPERIMENTAL
|

help
|
|
This enables support for sparse irqs. This is useful in general
|
|
as most CPUs have a fairly sparse array of IRQ vectors, which
|
|
the irq_desc then maps directly on to. Systems with a high
|
|
number of off-chip IRQs will want to treat this as
|
|
experimental until they have been independently verified.

Selecting this option will wakeup the User Break Controller (UBC) on
|
|
startup. Although the UBC is left in an awake state when the processor
|
|
comes up, some boot loaders misbehave by putting the UBC to sleep in a

power saving state, which causes issues with things like ptrace().

Dreamcast with a serial line terminal or a remote network
