1109 Please make sure to pick the right CPU type. Linux/MIPS is not
1110 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1111 *not* work on R4000 machines and vice versa. However, since most
1112 of the supported machines have an R4000 (or similar) CPU, R4x00
1113 might be a safe bet. If the resulting kernel does not work,
1114 try to recompile with R3000.

1960 kexec is a system call that implements the ability to shutdown your
1961 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001962 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001963 you can start any kernel with it, not just Linux.
1964
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001965 The name comes from the similarity to the exec system call.

1967 It is an ongoing process to be certain the hardware in a machine
1968 is properly shutdown, so do not be surprised if this code does not
1969 initially work for you. It may help to enable device hotplugging

1978 This kernel feature is useful for number crunching applications
1979 that may need to compute untrusted bytecode during their

1982 syscalls, it's possible to isolate those applications in
1983 their own address space using seccomp. Once seccomp is
