This module installs a reboot hook, such that if reboot() is
|
|
invoked with a string argument NNN, "NNN" is copied to the
|
|
"LoaderEntryOneShot" EFI variable, to be read by the
|
|
bootloader. If the string matches one of the boot labels
|
|
defined in its configuration, the bootloader will boot once
|
|
to that label. The "LoaderEntryRebootReason" EFI variable is
|
|
set with the reboot reason: "reboot" or "shutdown". The
|
|
bootloader reads this reboot reason and takes particular
|
|
action according to its policy.

This driver uses the efi.<service> function pointers directly instead
|

of going through the efivar API, because it is not trying to test the
|

kernel subsystem, just for testing the UEFI runtime service
|
|
interfaces which are provided by the firmware. This driver is used
|
|
by the Firmware Test Suite (FWTS) for testing the UEFI runtime
|
|
interfaces readiness of the firmware.
