Hello. I have to write rights to svn. And even if I had I would never commit a code in such stage (not reviewed, tested only on qemu, still in developement)
However I'll rediff the code against HEAD when I'll have time

Dear Vladimir,
I tried rev 2030 and 2037.
And I also had few errors on patching stage.

I think it is a good idea to commit your code to head branch.
I will wait for it and try it asap.

Thank you.

Try with 2030. Actually it's diffed against 2030+some of my posted and
unposted patches. If it still doesn't apply please report I'll update and
rediff it against HEAD.
I'm interested in behaviour of this code on real EFI however doesn't expect
this version to be able to work completely.
x86_64-efi isn't supported by this patch yet
Also if xen uses any bios interrupts it will probably triple fault. On IRC
we discussed a possibility of loading seabios and it's probably feasible but
will take more time

Vladimir,

First of all I'd like to say thank you for a quick feedback and
development.

I  tried to apply your patches and test it on my Apple Xserve Intel 32
bit.
I've done following;

# svn co svn://svn.sv.gnu.org/grub/trunk/grub2
# cd ./grub2
# patch -b -p1 < ./uppermem.diff
patching file conf/i386.rmk
patching file lib/i386/uppermem.c
 --- it's Ok
 --- Than
#  patch -b -p1 < ./efiboot.diff
patching file conf/common.rmk
Hunk #1 succeeded at 503 (offset -4 lines).
patching file conf/i386-coreboot.rmk
Hunk #1 succeeded at 99 with fuzz 2 (offset -3 lines).
Hunk #2 succeeded at 200 (offset -10 lines).
patching file conf/i386-efi.rmk
Hunk #1 FAILED at 80.
Hunk #2 FAILED at 103.
...
etc.


I would like to ask you for what revision of grub2 this patches where
done?
Do I have to checkout any specific branch of grub2?

Thank you in advance.

Hello. Here is an initial version of patch for booting multiboot kernels
on
i386-efi. No Changelog yet because it's not for inclusion yet.
