1997 | To support multiple TC microthreads acting as "CPUs" within | |
1998 | a VPE, VPE-wide interrupt mask bits must be specially manipulated | |

2399 | kexec is a system call that implements the ability to shutdown your | |
2400 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2401 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
2402 | you can start any kernel with it, not just Linux. |
2403 | ||
01dd2fbf | 2404 | The name comes from the similarity to the exec system call. |

2419 | a crash by kdump/kexec. The crash dump kernel must be compiled | |

2440 | This kernel feature is useful for number crunching applications | |
2441 | that may need to compute untrusted bytecode during their | |
2442 | execution. By using pipes or other transports made available to | |
2443 | the process as file descriptors supporting the read/write | |
2444 | syscalls, it's possible to isolate those applications in | |
2445 | their own address space using seccomp. Once seccomp is | |
2446 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2447 | and the task is only allowed to execute a few safe syscalls | |

2455 | help |
2456 | When this is enabled, the kernel will support use of 64-bit floating | |
2457 | point registers with binaries using the O32 ABI along with the | |
2458 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2459 | 32-bit MIPS systems this support is at the cost of increasing the | |
2460 | size and complexity of the compiled FPU emulator. Thus if you are | |
2461 | running a MIPS32 system and know that none of your userland binaries | |
2462 | will require 64-bit floating point, you may wish to reduce the size | |
2463 | of your kernel & potentially improve FP emulation performance by | |
2464 | saying N here. | |

2466 | Although binutils currently supports use of this flag the details |
2467 | concerning its effect upon the O32 ABI in userland are still being | |
2468 | worked on. In order to avoid userland becoming dependant upon current | |
2469 | behaviour before the details have been finalised, this option should | |
2470 | be considered experimental and only enabled by those working upon | |
2471 | said details. | |
