1131 Please make sure to pick the right CPU type. Linux/MIPS is not
1132 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1133 *not* work on R4000 machines and vice versa. However, since most
1134 of the supported machines have an R4000 (or similar) CPU, R4x00
1135 might be a safe bet. If the resulting kernel does not work,
1136 try to recompile with R3000.

1982 kexec is a system call that implements the ability to shutdown your

David Sterba3dde6ad2007-05-09 07:12:20 +02001984 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001985 you can start any kernel with it, not just Linux.
1986
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001987 The name comes from the similarity to the exec system call.

1989 It is an ongoing process to be certain the hardware in a machine
1990 is properly shutdown, so do not be surprised if this code does not
1991 initially work for you. It may help to enable device hotplugging

2000 This kernel feature is useful for number crunching applications
2001 that may need to compute untrusted bytecode during their
2002 execution. By using pipes or other transports made available to
2003 the process as file descriptors supporting the read/write
2004 syscalls, it's possible to isolate those applications in
2005 their own address space using seccomp. Once seccomp is
2006 enabled via /proc/<pid>/seccomp, it cannot be disabled
2007 and the task is only allowed to execute a few safe syscalls
