Defi-stub.rst9 jumps to are collectively known as the "EFI boot stub", and live in
10 arch/x86/boot/header.S and drivers/firmware/efi/libstub/x86-stub.c,
11 respectively. For ARM the EFI stub is implemented in
13 drivers/firmware/efi/libstub/arm32-stub.c. EFI stub code that is shared
17 masquerades as a PE/COFF image and the EFI stub is linked into the
18 kernel. The arm64 EFI stub lives in arch/arm64/kernel/efi-entry.S
19 and drivers/firmware/efi/libstub/arm64-stub.c.
21 By using the EFI boot stub it's possible to boot a Linux kernel
23 elilo. Since the EFI boot stub performs the jobs of a boot loader, in
26 The EFI boot stub is enabled with the CONFIG_EFI_STUB kernel option.
