544 | If you say Y here, support is built into the kernel to | |
545 | make ESI calls. ESI calls are used to support vendor-specific | |
546 | firmware extensions, such as the ability to inject memory-errors | |
547 | for test-purposes. If you're unsure, say N. | |

551 | help | |
552 | This driver installs a global ACPI Operation Region handler for | |
553 | region 0xA1. AML methods can use this OpRegion to call arbitrary | |
554 | native firmware functions. The driver installs the OpRegion | |
555 | handler if there is an HPQ5001 device or if the user supplies | |
556 | the "force" module parameter, e.g., with the "aml_nfw.force" | |
557 | kernel command line option. | |

564 | help | |
565 | kexec is a system call that implements the ability to shutdown your | |
566 | current kernel, and to start another kernel. It is like a reboot | |
567 | but it is independent of the system firmware. And like a reboot | |
568 | you can start any kernel with it, not just Linux. | |
569 | ||
570 | The name comes from the similarity to the exec system call. | |
571 | ||
572 | It is an ongoing process to be certain the hardware in a machine | |
573 | is properly shutdown, so do not be surprised if this code does not | |
574 | initially work for you. It may help to enable device hotplugging | |
575 | support. As of this writing the exact hardware interface is | |
576 | strongly in flux, so no good recommendation can be made. | |
