483 | help | |
484 | This driver installs a global ACPI Operation Region handler for | |
485 | region 0xA1. AML methods can use this OpRegion to call arbitrary | |
486 | native firmware functions. The driver installs the OpRegion | |
487 | handler if there is an HPQ5001 device or if the user supplies | |
488 | the "force" module parameter, e.g., with the "aml_nfw.force" | |
489 | kernel command line option. | |

496 | help | |
497 | kexec is a system call that implements the ability to shutdown your | |
498 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 499 | but it is independent of the system firmware. And like a reboot |
a7956113 ZN |
500 | you can start any kernel with it, not just Linux. |

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