I think that you could change that to Good. I am working
on it. Migration to xbi struct is almost finished and
multiboot2 protocol works on machines with legacy BIOS.
Now I am working on multiboot2 protocol for machines
with EFI. Yesterday, I discovered some issues related
to memory map passed via this protocol. Sadly it looks
that taking into account current GRUB2 implementation
only workaround is available. Final proper solution would
require some changes in GRUB2. I will do that later.


* Guest EFI booting
  - status: tianocore in-tree, some build problems.
    Needs new owner.
I could take over ownership of this but it would have
lowest priority on my task list now (major stuff only:
1 - multiboot2 protocl, 2 - EFI support for Xen in Linux
Kernel, 3 - guest EFI booting).

OK -- I think for now then I'll leave it unclaimed, so that if any other enterprising developers show up they can take a look at it.

* Xen EFI feature: pvops dom0 able to make use of EFI run-time
services (external)

I am going to start work on it when I finish work on multiboot2 protocol.

Additionally, I think that:
   - new kexec implementation should be added to this list;
     David Vrabel work on this; I think that patches are
     quite mature and need only some polishing,
   - unmodified_drivers should be removed because as I know
     they are not maintained for very long time; if you
     agree I could do that,
   - as I saw there is a quite big mess in directory structure
     used by installed Xen related stuff (especially in /var
     and /usr); I have done some patches for myself but they
     require some improvements to do public release; if you wish
     I could work on this too.

It's up to you really -- if you are set on working on it, I'll put it on the list; but there is plenty to do othewise. :-) What kinds of changes did you have in mind in particular?
