  1571. help
  1572. kexec is a system call that implements the ability to shutdown your
  1573. current kernel, and to start another kernel. It is like a reboot
  1574. but it is independent of the system firmware. And like a reboot
  1575. you can start any kernel with it, not just Linux.
  1576. The name comes from the similarity to the exec system call.
  1577. It is an ongoing process to be certain the hardware in a machine
  1578. is properly shutdown, so do not be surprised if this code does not
  1579. initially work for you. It may help to enable device hotplugging
  1580. support. As of this writing the exact hardware interface is
  1581. strongly in flux, so no good recommendation can be made.

  1587. This kernel feature is useful for number crunching applications
  1588. that may need to compute untrusted bytecode during their
  1589. execution. By using pipes or other transports made available to
  1590. the process as file descriptors supporting the read/write
  1591. syscalls, it's possible to isolate those applications in
  1592. their own address space using seccomp. Once seccomp is
  1593. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1594. and the task is only allowed to execute a few safe syscalls
  1595. defined by each seccomp mode.
