If you say Y here, you are able to get EFI (Extensible Firmware
|
||
|
|
Interface) variable information via sysfs. You may read,
|
||
|
|
write, create, and destroy EFI variables through this interface.
|
||
|
|
|
||
|
|
Note that using this driver in concert with efibootmgr requires
|
||
|
|
at least test release version 0.5.0-test3 or later, which is
|
||
|
|
available from Matt Domsch's website located at:

Export efi runtime memory maps to /sys/firmware/efi/runtime-map.

That memory map is used for example by kexec to set up efi virtual

mapping the 2nd kernel, but can also be used for debugging purposes.
