Subject: [PATCH 0/2 -v3] x86_64 EFI boot support
Date: Fri, 02 Nov 2007 10:49:35 +0800 [thread overview]
Message-ID: <1193971775.11724.30.camel@caritas-dev.intel.com> (raw)
Following sets of patches add EFI/UEFI (Unified Extensible Firmware
Interface) boot support to x86_64 architecture.
The patches have been tested against 2.6.24-rc1 kernel on Intel
platforms with EFI1.10 and UEFI2.0 firmware. With this set of patches
applied, the 64bit and 32bit x86 kernel can be booted on x86_64
machine with UEFI64 firmware.
Because the EFI memory map is converted to E820 map in bootloader, now
the only needed code for booting Linux kernel on x86_64 UEFI platform
is the framebuffer driver.
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 boot document
v3:
- The VIDEO_TYPE_EFI is changed to 0x70 to group VIDEO_TYPE_<XX> better.
v2:
- The include files of efifb.c is cleaned up.
- Make CONFIG_FB_EFI not depend on CONFIG_EFI.
Best Regards,
Huang Ying
