Add 'copy_staging' command to control this. For now, by default the

On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data

Add a man page for gptboot.efi. Describe when and how to use this as it differs
from the BIOS cases. Include cross reference for the preferred method described
in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to

This man page was heavily copied from the gptboot.8 man page by Warren Block.
They are different enough to need separate man pages for clarity, but there's
enough similarity that I worry about the duplication. In the really long term,
gptboot(8) will disappear, so having the same info here will help when that
day comes. In the short to medium term, the information is likely to not
change in gptboot(8) and any changes to gptboot.efi(8) will be easier to
make in a separate copy.
loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have
referenced gptboot.efi(8) from there.

Add some basic multiboot2 infrastructure to the EFI loader in order to
be capable of booting a FreeBSD/Xen dom0 when booted from UEFI.
Only a very limited subset of the multiboot2 protocol is implemented
in order to support enough to boot into Xen, the implementation
doesn't intend to be a full multiboot2 capable implementation.
Such multiboot2 functionality is hooked up into the amd64 EFI loader,
which is the only architecture that supports Xen dom0 on FreeBSD.
The options to boot a FreeBSD/Xen dom0 system are exactly the same as
on BIOS, and requires setting the xen_kernel and xen_cmdline options
in loader.conf.

This mirrors the functionality of the BIOS amd64 bi_load function,
that stashes the absolute address of the module metadata. This is
required for booting as a Xen dom0 that does relocate the modulep and
the loaded modules, and thus requires adjusting the offset.

functionality for Xen dom0 loading.

Some systems may provide multiple GOP instances and not all are
bound to hardware. The current loader is picking up the first GOP,
which may not be usable. Instead we load the GOP handle array,
and test every handle to have registered ConOut protocol. If ConOut is
present, we can use this GOP handle to open GOP protocol.
We do select font based on desired terminal size, we do query
UEFI terminal size with conout->QueryMode(), but by mistake, the fallback
values are used.
Pass gfx_state to efi_find_framebuffer(), so we can pick between
GOP and UGA in efi_find_framebuffer(), also we can then
set up struct gen_fb in gfx_state from efifb and isolate efi fb data
processing into framebuffer.c.
This change does allow us to clean up efi_cons_init() and reduce
BS->LocateProtocol() calls.
A little downside is that we now need to translate gen_fb back to
efifb in bootinfo.c (for passing to kernel), and we need to add few
-I options to CFLAGS.

buildworld already runs the stand build in parallel[1], so make it easier to
identify ordering issues by properly establishing dependencies or adding
.WAIT where needed.
Everything in stand/ relies on libsa, either directly or indirectly, because
libsa build is where the stand headers get installed and it gets linked in
most places.
Interpreters depend on their libs, machine dirs usually depend on top-level
libs that are getting built and at least one of the interpreter flavors.
For i386, order btx/libi386/libfirewire before everything else using a
big-ol-.WAIT hammer. btx is the most common dependency, but the others are
used sporadically. This seems to be where the race reporting on the mailing
list is- AFAICT, the following sequence is happening:
1.) One of the loaders gets built based on stale btx/btxldr
2.) btx/btxldr gets rebuilt
3.) installworld triggers loader rebuild because btx was rebuilt after
This seems like the most plausible explanation, as they've verified system
time and timestamps.
While we're here, let's switch stand/ over to a completely parallel build so
we can work out these kinds of issues in isolation rather than in the middle
of a larger build.

This leads, among other things, to bhyve only producing output in the
serial connection once we leave the boot loader. This restores the
dual headed boot on bhyve + UEFI (as we did in 11.2), but will favor

During devswitch probe, we pick boot pool based on boot disk, if the boot
disk happens to have multiple pools in freebsd-zfs partitions, the current
code does pick last pool from boot disk as boot pool. While there is no
way at that stage to test, the more logical approach would be to pick
first matching pool.
This patch is assuming we do pass pool guid pointer with guid value 0,
this will help us to determine, if the guid value is already set or not.
The general suggestion would be not to share disk between different pools.
