Following sets of patches add EFI/UEFI (Unified Extensible Firmware Interface) support to x86_64 architecture. The patches have been tested against 2.6.23-rc1 kernel on Intel platforms with EFI1.10 and UEFI2.0 firmware.
UEFI specification can be found here: http://www.uefi.org
For booting the UEFI x86_64 enabled kernel, the machine with EFI/UEFI firmware and the support of bootloader is required. Detailed usage guide can be found in Documentation/x86_64/uefi.txt, which is added in the patch: efi-doc.patch.
Issues _not_ addressed (per feedback from Eric Biederman)
- Virtual mode support is still retained in this patch. There is at least one EFI call is fast path: efi_set_rtc_mmss, which must complete as soon as possible.
- The variable efi_enabled is used throughout across architecutres if CONFIG_EFI option is enabled. The i386 code also uses this variable. This is something that can be revisited with code consolidation across architectures.
Looking forward to your comments,
