1090 Please make sure to pick the right CPU type. Linux/MIPS is not
1091 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1092 *not* work on R4000 machines and vice versa. However, since most
1093 of the supported machines have an R4000 (or similar) CPU, R4x00
1094 might be a safe bet. If the resulting kernel does not work,
1095 try to recompile with R3000.

1936 help
1937 kexec is a system call that implements the ability to shutdown your
1938 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001939 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001940 you can start any kernel with it, not just Linux.
1941
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001942 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001943
1944 It is an ongoing process to be certain the hardware in a machine
1945 is properly shutdown, so do not be surprised if this code does not
1946 initially work for you. It may help to enable device hotplugging
1947 support. As of this writing the exact hardware interface is
1948 strongly in flux, so no good recommendation can be made.

1954 help
1955 This kernel feature is useful for number crunching applications
1956 that may need to compute untrusted bytecode during their
1957 execution. By using pipes or other transports made available to
1958 the process as file descriptors supporting the read/write
1959 syscalls, it's possible to isolate those applications in
1960 their own address space using seccomp. Once seccomp is
1961 enabled via /proc/<pid>/seccomp, it cannot be disabled
1962 and the task is only allowed to execute a few safe syscalls
1963 defined by each seccomp mode.

2029 The EISA bus provided some of the features of the IBM MicroChannel
