can simulate a MIPS32 4Kc system. This patch adds support for the

|
system architecture that currently is being simulated by Qemu. It
|
|
will eventually be removed again when Qemu has the capability to
|
|
simulate actual MIPS hardware platforms. More information on Qemu
|

This option enables special console drivers which allow the kernel

to print messages very early in the bootup process.
|
|
|
|
This is useful for kernel debugging when your machine crashes very
|
|
early before the console code is initialized. For normal operation,
|
|
it is not recommended because it looks ugly on some machines and
|
|
doesn't cooperate with an X server. You should normally say N here,

unless you want to debug such a crash.

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 32 for 32-bit
|
|
kernel and 64 for 64-bit kernels; the minimum value which makes
|
|
sense is 1 for Qemu (useful only for kernel debugging purposes)
|
|
and 2 for all others.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image. For best
|
|
performance should round up your number of processors to the next
|
|
power of two.

MIPS R10000 does support a 44 bit / 16TB address space as opposed to

config KEXEC

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 similiarity 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

|
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 /proc/<pid>/seccomp, it cannot be disabled
|
|
and the task is only allowed to execute a few safe syscalls
|
|
defined by each seccomp mode.
|
|

If unsure, say Y. Only embedded should say N here.

The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
The EISA bus provided some of the features of the IBM MicroChannel
|
|
bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
|

Say Y here if you are building a kernel for an EISA-based machine.
