484 | bool "ESI (Extensible SAL Interface) support" | |
485 | help | |
486 | If you say Y here, support is built into the kernel to | |
487 | make ESI calls. ESI calls are used to support vendor-specific | |
488 | firmware extensions, such as the ability to inject memory-errors | |
489 | for test-purposes. If you're unsure, say N. | |

492 | bool "Support ACPI AML calls to native firmware" | |
493 | help | |
494 | This driver installs a global ACPI Operation Region handler for | |
495 | region 0xA1. AML methods can use this OpRegion to call arbitrary | |
496 | native firmware functions. The driver installs the OpRegion | |
497 | handler if there is an HPQ5001 device or if the user supplies | |
498 | the "force" module parameter, e.g., with the "aml_nfw.force" | |
499 | kernel command line option. | |

506 | help | |
507 | kexec is a system call that implements the ability to shutdown your | |
508 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 509 | but it is independent of the system firmware. And like a reboot |
a7956113 ZN |
510 | you can start any kernel with it, not just Linux. |

513 | |
514 | It is an ongoing process to be certain the hardware in a machine | |
515 | is properly shutdown, so do not be surprised if this code does not | |
516 | initially work for you. It may help to enable device hotplugging | |
517 | support. As of this writing the exact hardware interface is | |
518 | strongly in flux, so no good recommendation can be made. | |
