792 Some MIPS machines can be configured for either little or big endian
Ralf Baechle5e83d432005-10-29 19:32:41 +0100793 byte order. These modes require different kernels and a different
794 Linux distribution. In general there is one prefered byteorder for a
795 particular system but some systems are just as commonly used in the
796 one or the other endianess.

1030 Please make sure to pick the right CPU type. Linux/MIPS is not
1031 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1032 *not* work on R4000 machines and vice versa. However, since most
1033 of the supported machines have an R4000 (or similar) CPU, R4x00
1034 might be a safe bet. If the resulting kernel does not work,
1035 try to recompile with R3000.

1634 help
1635 This kernel feature is useful for number crunching applications
1636 that may need to compute untrusted bytecode during their
1637 execution. By using pipes or other transports made available to
1638 the process as file descriptors supporting the read/write
1639 syscalls, it's possible to isolate those applications in
1640 their own address space using seccomp. Once seccomp is
1641 enabled via /proc/<pid>/seccomp, it cannot be disabled
1642 and the task is only allowed to execute a few safe syscalls
1643 defined by each seccomp mode.
1644
1645 If unsure, say Y. Only embedded should say N here.
