designed to be generic, i.e. Kernels compiled for R3000 CPUs will

*not* work on R4000 machines and vice versa. However, since most

of the supported machines have an R4000 (or similar) CPU, R4x00

might be a safe bet. If the resulting kernel does not work,

try to recompile with R3000.

-mfix-loongson2f-nop and -mfix-loongson2f-jump options.

Loongson 2F03 and later have fixed these issues and no workarounds

are needed. The workarounds have no significant side effect on them
|

but may decrease the performance of the system so this option should

be disabled unless the kernel is intended to be run on 2F01 or 2F02

systems.

This is a kernel model which is known a VSMP but lately has been

marketesed into SMVP.
|

Virtual SMP uses the processor's VPEs to implement virtual
|
|
processors. In currently available configuration of the 34K processor
|
|
this allows for a dual processor. Both processors will share the same
|
|
primary caches; each will obtain the half of the TLB for it's own
|
|
exclusive use. For a layman this model can be described as similar to
|
|
what Intel calls Hyperthreading.

This allows you to specify the maximum number of CPUs which this

kernel and 64 for 64-bit kernels; the minimum value which makes

sense is 1 for Qemu (useful only for kernel debugging purposes)

This is purely to save memory - each supported CPU adds

approximately eight kilobytes to the kernel image. For best

help
|
|
MIPS R10000 does support a 44 bit / 16TB address space as opposed to
|
|
previous 64-bit processors which only supported 40 bit / 1TB. If you
|
|
need processes of more than 1TB virtual address space, say Y here.

recommended for normal users.

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 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
|
|
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.
