Matt LaPlante01dd2fb2007-10-20 01:34:40 +0200464 Adds support for MC error injection. If enabled, the kernel
465 will provide a sysfs interface for user applications to
466 call MC error injection PAL procedures to inject various errors.
Fenghua Yue9ef08b2006-12-08 16:06:01 -0800467 This is a useful tool for MCA testing.

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

497 help
498 kexec is a system call that implements the ability to shutdown your
499 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +0200500 but it is independent of the system firmware. And like a reboot
Zou Nan haia79561132006-12-07 09:51:35 -0800501 you can start any kernel with it, not just Linux.
502
Matt LaPlante01dd2fb2007-10-20 01:34:40 +0200503 The name comes from the similarity to the exec system call.
Zou Nan haia79561132006-12-07 09:51:35 -0800504
505 It is an ongoing process to be certain the hardware in a machine
506 is properly shutdown, so do not be surprised if this code does not
507 initially work for you. It may help to enable device hotplugging
508 support. As of this writing the exact hardware interface is
509 strongly in flux, so no good recommendation can be made.
