483 | help | |
484 | If you say Y here, you are able to get PAL (Processor Abstraction | |
485 | Layer) information in /proc/pal. This contains useful information | |
486 | about the processors in your systems, such as cache and TLB sizes | |
487 | and the PAL firmware version in use. | |
488 | ||
489 | To use this option, you have to ensure that the "/proc file system | |
490 | support" (CONFIG_PROC_FS) is enabled, too. | |

495 | Adds support for MC error injection. If enabled, the kernel |
496 | will provide a sysfs interface for user applications to | |
497 | call MC error injection PAL procedures to inject various errors. | |

516 | This driver installs a global ACPI Operation Region handler for | |

528 | help | |
529 | kexec is a system call that implements the ability to shutdown your | |
530 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 531 | but it is independent of the system firmware. And like a reboot |

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

536 | It is an ongoing process to be certain the hardware in a machine | |

538 | initially work for you. It may help to enable device hotplugging | |
539 | support. As of this writing the exact hardware interface is | |
540 | strongly in flux, so no good recommendation can be made. | |
