[Xen-devel] [PATCH v7 00/14] x86: multiboot2 protocol support

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

Hi,

I am sending seventh version of multiboot2 protocol support for
legacy BIOS and EFI platforms. This patch series release contains
fixes for all known issues.

The final goal is xen.efi binary file which could be loaded by EFI
loader, multiboot (v1) protocol (only on legacy BIOS platforms) and
multiboot2 protocol. This way we will have:
  - smaller Xen code base,
  - one code base for xen.gz and xen.efi,
  - one build method for xen.gz and xen.efi;
    xen.efi will be extracted from xen(-syms)
    file using objcopy or special custom tool,
  - xen.efi build will not so strongly depend
    on a given GCC and binutils version.

Here is short list of changes since v6:
  - new patches: 01,
  - changed patches: 02-04, 07-10,
  - RFC patches: 07.

Patches 12-14 were reviewed by nobody last time.

Julien Grall raised some concerns in regards to EFI boot allocator
implementation on ARM. So, I marked patch #07 which introduces it
as RFC. Hence, I am asking ARM guys to review it and suggest needed
changes. If you have any questions please drop me a line.

I hope that (at least some) features provided by this patch series
will be included in Xen 4.8 release in one way or another.

If you are not interested in this patch series at all please
drop me a line and I will remove you from distribution list.

Daniel
