[PATCH 0/2 -v2 resend] x86_64 EFI boot support

[PATCH 0/2 -v2 resend] x86_64 EFI boot support

[Huang, Ying]

This patch set has been dropped because the 32-bit boot protocol is
not ready. Now, the 32-bit boot protocol has been merged, so I resend
this patch set.

Can this patch set and 32-bit boot protocol document patch catch up
with the merge window of 2.6.24?


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 64 bit and 32 bit 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


v2:

- The include files of efifb.c is cleaned up.
- Make CONFIG_FB_EFI not depend on CONFIG_EFI.

Can this patchset be merged into mainline kernel? This patchset has been
in -mm tree from 2.6.23-rc2-mm2 on. Andrew Moton has suggested it to be
merged into 2.6.24 during early merge window of 2.6.24. It was not
merged into mainline because the 32-bit boot protocol has not been done.

But now, the 32-bit boot protocol has been merged into mainline. So can
this patchset be merged into mainline kernel now?

I stopped paying attention, sorry.  Have all the outstanding issues been
addressed?

The "EFI boot" patchset looks fairly unobtrusive to me.  One objection: 
the VIDEO_TYPE_ numbers appear split up into groups; and the EFI one 
probably should be 0x70 instead of 0x24.

Other than that, I just need to verify it doesn't break anything.

"EFI runtime" I have not had time to review yet.

Should I change this and resend the patchset? Or you modify it before
merging?

I'd be easier if you could change and resend.

That's all right. I think there is no big issue with this patchset, just
a framebuffer driver and the document.
