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

1093 Please make sure to pick the right CPU type. Linux/MIPS is not
1094 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1095 *not* work on R4000 machines and vice versa. However, since most
1096 of the supported machines have an R4000 (or similar) CPU, R4x00
1097 might be a safe bet. If the resulting kernel does not work,
1098 try to recompile with R3000.

Linus Torvalds1da177e2005-04-16 15:20:36 -07001929 help
1930 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1931 previous 64-bit processors which only supported 40 bit / 1TB. If you
1932 need processes of more than 1TB virtual address space, say Y here.
1933 This will result in additional memory usage, so it is not
1934 recommended for normal users.

1938 depends on EXPERIMENTAL
1939 help
1940 kexec is a system call that implements the ability to shutdown your
1941 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001942 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001943 you can start any kernel with it, not just Linux.
1944
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001945 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001946
1947 It is an ongoing process to be certain the hardware in a machine
1948 is properly shutdown, so do not be surprised if this code does not
1949 initially work for you. It may help to enable device hotplugging
1950 support. As of this writing the exact hardware interface is
1951 strongly in flux, so no good recommendation can be made.

1957 help
1958 This kernel feature is useful for number crunching applications
1959 that may need to compute untrusted bytecode during their
1960 execution. By using pipes or other transports made available to
1961 the process as file descriptors supporting the read/write
1962 syscalls, it's possible to isolate those applications in
1963 their own address space using seccomp. Once seccomp is
1964 enabled via /proc/<pid>/seccomp, it cannot be disabled
1965 and the task is only allowed to execute a few safe syscalls
1966 defined by each seccomp mode.

2030 developed as an open alternative to the IBM MicroChannel bus.

2032 The EISA bus provided some of the features of the IBM MicroChannel
2033 bus while maintaining backward compatibility with cards made for
2034 the older ISA bus. The EISA bus saw limited use between 1988 and
