[Xen-devel] [PATCH v3 00/16] x86: multiboot2 protocol support

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

Hi,

I am sending, long awaited, third version of multiboot2 protocol
support for legacy BIOS and EFI platforms. It fixes all major issues
discovered until now. There are still some minor problems which should
be fixed in one way or another. I will address them in next releases.

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 are short list of changes:
  - new patches: 01, 07, 09,
  - changed patches: 02, 03, 04, 06, 08, 10, 11, 13, 14, 15, 16,
  - RFC patches: 12, 13, 15; if it is needed we could discuss at
    least #12 and #15 at Xen Project Hackathon in Cambridge.

This patch series was build with following tools:
  - gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
    and binutils 2.17-3+etch1,
  - gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
    and binutils 2.23.2-2.el6,
  - gcc version 4.7.2 (Debian 4.7.2-5)
    and binutils 2.22-8,
  - gcc version 5.1.1 20150618 (Red Hat 5.1.1-4) (GCC)
    and binutils 2.25-9.fc22.

I hope that starting from now there will be faster turnaround
of this patch series.

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
