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.

1918 help
1919 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1920 previous 64-bit processors which only supported 40 bit / 1TB. If you
1921 need processes of more than 1TB virtual address space, say Y here.
1922 This will result in additional memory usage, so it is not
1923 recommended for normal users.

1928 help
1929 kexec is a system call that implements the ability to shutdown your
1930 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 1931 but it is independent of the system firmware. And like a reboot
ea6e942b

1932 you can start any kernel with it, not just Linux.
1933
01dd2fbf 1934 The name comes from the similarity to the exec system call.

1936 It is an ongoing process to be certain the hardware in a machine
1937 is properly shutdown, so do not be surprised if this code does not
1938 initially work for you. It may help to enable device hotplugging
1939 support. As of this writing the exact hardware interface is
1940 strongly in flux, so no good recommendation can be made.

1945 default y
1946 help
1947 This kernel feature is useful for number crunching applications
1948 that may need to compute untrusted bytecode during their
1949 execution. By using pipes or other transports made available to
1950 the process as file descriptors supporting the read/write
1951 syscalls, it's possible to isolate those applications in
1952 their own address space using seccomp. Once seccomp is
1953 enabled via /proc/<pid>/seccomp, it cannot be disabled
1954 and the task is only allowed to execute a few safe syscalls
1955 defined by each seccomp mode.
1956
1957 If unsure, say Y. Only embedded should say N here.

2022 The Extended Industry Standard Architecture (EISA) bus was
2023 developed as an open alternative to the IBM MicroChannel bus.
2024
2025 The EISA bus provided some of the features of the IBM MicroChannel
2026 bus while maintaining backward compatibility with cards made for
2027 the older ISA bus. The EISA bus saw limited use between 1988 and
2028 1995 when it was made obsolete by the PCI bus.
