9 | If you say Y here, you are able to get EFI (Extensible Firmware | |
10 | Interface) variable information via sysfs. You may read, | |
11 | write, create, and destroy EFI variables through this interface. | |
12 | ||
13 | Note that using this driver in concert with efibootmgr requires | |
14 | at least test release version 0.5.0-test3 or later, which is | |
0e4ca02b | 15 | available from: |

26 | Say Y here to enable use efivars as a backend to pstore. This | |

35 | Saying Y here will disable the use of efivars as a storage | |
36 | backend for pstore by default. This setting can be overridden | |

44 | Export efi runtime memory maps to /sys/firmware/efi/runtime-map. | |
45 | That memory map is used for example by kexec to set up efi virtual | |
