2053 | help | |
2054 | kexec is a system call that implements the ability to shutdown your | |
2055 | current kernel, and to start another kernel. It is like a reboot | |
2056 | but it is independent of the system firmware. And like a reboot | |
2057 | you can start any kernel with it, not just Linux. | |
2058 | ||
2059 | The name comes from the similarity to the exec system call. | |
2060 | ||
2061 | It is an ongoing process to be certain the hardware in a machine | |
2062 | is properly shutdown, so do not be surprised if this code does not | |
2063 | initially work for you. It may help to enable device hotplugging | |
2064 | support. As of this writing the exact hardware interface is | |
2065 | strongly in flux, so no good recommendation can be made. | |

2072 | This kernel feature is useful for number crunching applications | |

2074 | execution. By using pipes or other transports made available to | |
2075 | the process as file descriptors supporting the read/write | |
2076 | syscalls, it's possible to isolate those applications in | |
2077 | their own address space using seccomp. Once seccomp is | |
2078 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2079 | and the task is only allowed to execute a few safe syscalls | |
