2069 | MIPS R10000 does support a 44 bit / 16TB address space as opposed to | |
2070 | previous 64-bit processors which only supported 40 bit / 1TB. If you | |

2076 | bool "Kexec system call (EXPERIMENTAL)" | |
2077 | depends on EXPERIMENTAL | |
2078 | help | |
2079 | kexec is a system call that implements the ability to shutdown your | |
2080 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2081 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
2082 | you can start any kernel with it, not just Linux. |
2083 | ||
01dd2fbf | 2084 | The name comes from the similarity to the exec system call. |
ea6e942b AN |

2086 | It is an ongoing process to be certain the hardware in a machine | |
2087 | is properly shutdown, so do not be surprised if this code does not | |
2088 | initially work for you. It may help to enable device hotplugging | |
2089 | support. As of this writing the exact hardware interface is | |

2096 | help | |
2097 | This kernel feature is useful for number crunching applications | |
2098 | that may need to compute untrusted bytecode during their | |
2099 | execution. By using pipes or other transports made available to | |
2100 | the process as file descriptors supporting the read/write | |
2101 | syscalls, it's possible to isolate those applications in | |
2102 | their own address space using seccomp. Once seccomp is | |
2103 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2104 | and the task is only allowed to execute a few safe syscalls | |
2105 | defined by each seccomp mode. | |
