743 | This option supports all of the Octeon reference boards from Cavium | |
744 | Networks. It builds a kernel that dynamically determines the Octeon | |
745 | CPU type and supports all known board reference implementations. | |
746 | Some of the supported boards are: | |
747 | EBT3000 | |
748 | EBH3000 | |
749 | EBH3100 | |
750 | Thunder | |

2397 | kexec is a system call that implements the ability to shutdown your | |
2398 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2399 | but it is independent of the system firmware. And like a reboot |

2400 | you can start any kernel with it, not just Linux. |

2454 | When this is enabled, the kernel will support use of 64-bit floating | |
2455 | point registers with binaries using the O32 ABI along with the | |
2456 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2457 | 32-bit MIPS systems this support is at the cost of increasing the | |
2458 | size and complexity of the compiled FPU emulator. Thus if you are | |
2459 | running a MIPS32 system and know that none of your userland binaries | |
2460 | will require 64-bit floating point, you may wish to reduce the size | |
2461 | of your kernel & potentially improve FP emulation performance by | |

2465 | concerning its effect upon the O32 ABI in userland are still being | |
2466 | worked on. In order to avoid userland becoming dependant upon current | |

2468 | be considered experimental and only enabled by those working upon | |
