627 Networks. It builds a kernel that dynamically determines the Octeon
628 CPU type and supports all known board reference implementations.
629 Some of the supported boards are:
630 EBT3000

633 Thunder
634 Kodama
635 Hikari

1111 Please make sure to pick the right CPU type. Linux/MIPS is not
1112 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1113 *not* work on R4000 machines and vice versa. However, since most
1114 of the supported machines have an R4000 (or similar) CPU, R4x00
1115 might be a safe bet. If the resulting kernel does not work,
1116 try to recompile with R3000.

1962 kexec is a system call that implements the ability to shutdown your

David Sterba3dde6ad2007-05-09 07:12:20 +02001964 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001965 you can start any kernel with it, not just Linux.
1966
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001967 The name comes from the similarity to the exec system call.

1970 is properly shutdown, so do not be surprised if this code does not
1971 initially work for you. It may help to enable device hotplugging

1980 This kernel feature is useful for number crunching applications
1981 that may need to compute untrusted bytecode during their

1983 the process as file descriptors supporting the read/write
1984 syscalls, it's possible to isolate those applications in
1985 their own address space using seccomp. Once seccomp is
