The result is that you can boot a bzImage on an EFI machine without the use of a boot loader by making the bzImage appear to the EFI firmware to be an EFI application. Also, a single bzImage can be booted on either a BIOS or EFI machine. Using the EFI boot stub has the advantage that the kernel is responsible for configuring the machine to the point where we can fully boot the kernel, so we are no longer at the mercy of the boot loader. This series is also available in the 'x86/efi-stub' branch at, git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/linux-2.6.git Matt Fleming (9): x86: Don't use magic strings for EFI loader signature efi.h: Add struct definition for boot time services efi.h: Add efi_image_loaded_t efi.h: Add allocation types for boottime->allocate_pages() efi.h: Add graphics protocol guid efi.h: Add boottime->locate_handle search types efi: Add EFI file I/O data types x86, efi: EFI boot stub support x86, efi: Make efi_call_phys_prelog() CONFIG_RELOCATABLE-aware arch/x86/Kconfig | 7 + arch/x86/boot/compressed/Makefile | 10 +- arch/x86/boot/compressed/eboot.c | 779 ++++++++++++++++++++++++++++++++ arch/x86/boot/compressed/efi_stub_32.S | 87 ++++ arch/x86/boot/compressed/efi_stub_64.S | 1 + arch/x86/boot/compressed/head_32.S | 13 + arch/x86/boot/compressed/head_64.S | 11 + arch/x86/boot/compressed/string.c | 9 + arch/x86/boot/header.S | 157 +++++++ arch/x86/boot/string.c | 35 ++ arch/x86/boot/tools/build.c | 27 ++ arch/x86/include/asm/efi.h | 4 + arch/x86/kernel/setup.c | 7 +- arch/x86/platform/efi/efi_32.c | 22 +- include/linux/efi.h | 130 ++++++- 15 files changed, 1282 insertions(+), 17 deletions(-) create mode 100644 arch/x86/boot/compressed/eboot.c create mode 100644 arch/x86/boot/compressed/efi_stub_32.S create mode 100644 arch/x86/boot/compressed/efi_stub_64.S -- 1.7.4.4
