1919 kexec is a system call that implements the ability to shutdown your
1920 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 1921 but it is independent of the system firmware. And like a reboot
ea6e942b
AN
1922 you can start any kernel with it, not just Linux.
1923
01dd2fbf 1924 The name comes from the similarity to the exec system call.

1926 It is an ongoing process to be certain the hardware in a machine
1927 is properly shutdown, so do not be surprised if this code does not
1928 initially work for you. It may help to enable device hotplugging
1929 support. As of this writing the exact hardware interface is
1930 strongly in flux, so no good recommendation can be made.

1936 help
1937 This kernel feature is useful for number crunching applications
1938 that may need to compute untrusted bytecode during their
1939 execution. By using pipes or other transports made available to
1940 the process as file descriptors supporting the read/write
1941 syscalls, it's possible to isolate those applications in
1942 their own address space using seccomp. Once seccomp is
1943 enabled via /proc/<pid>/seccomp, it cannot be disabled
1944 and the task is only allowed to execute a few safe syscalls
1945 defined by each seccomp mode.
1946

2012 The Extended Industry Standard Architecture (EISA) bus was
2013 developed as an open alternative to the IBM MicroChannel bus.

2015 The EISA bus provided some of the features of the IBM MicroChannel
2016 bus while maintaining backward compatibility with cards made for
2017 the older ISA bus. The EISA bus saw limited use between 1988 and
2018 1995 when it was made obsolete by the PCI bus.
