462 help
Matt LaPlante01dd2fb2007-10-20 01:34:40 +0200463 Adds support for MC error injection. If enabled, the kernel
464 will provide a sysfs interface for user applications to
465 call MC error injection PAL procedures to inject various errors.
Fenghua Yue9ef08b2006-12-08 16:06:01 -0800466 This is a useful tool for MCA testing.

475 help
476 If you say Y here, support is built into the kernel to
477 make ESI calls. ESI calls are used to support vendor-specific
478 firmware extensions, such as the ability to inject memory-errors
479 for test-purposes. If you're unsure, say N.

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
David Sterba3dde6ad2007-05-09 07:12:20 +0200499 but it is independent of the system firmware. And like a reboot
Zou Nan haia79561132006-12-07 09:51:35 -0800500 you can start any kernel with it, not just Linux.
501
Matt LaPlante01dd2fb2007-10-20 01:34:40 +0200502 The name comes from the similarity to the exec system call.
Zou Nan haia79561132006-12-07 09:51:35 -0800503
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.
