kexec is a system call that implements the ability to shutdown your
|
|
|
|
current kernel, and to start another kernel. It is like a reboot
|
2006-06-29 07:32:47 +02:00
|
|
|
but it is independent of the system firmware. And like a reboot
|
2006-01-17 07:14:19 +01:00
|
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
|
2006-06-29 07:32:47 +02:00
|
|
|
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.

This kernel feature is useful for number crunching applications

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

mode.

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

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.

Enabling this option will allow the kernel to implement some
|
|
|
|
atomic operations using a software implemention 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 insterrupts around the atomic sequence.

Find out whether you have ISA slots on your motherboard. ISA is the

name of a bus system, i.e. the way the CPU talks to the other stuff
|

inside your box. Other bus systems are PCI, EISA, MicroChannel
|

|
(MCA) or VESA. ISA is an older system, now being displaced by PCI;

newer boards don't support it. If you have ISA, say Y, otherwise N.
