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.
No functional change introduced, further patches will make use of this
functionality for Xen dom0 loading.

Xen requires that UEFI BootServices are enabled in order to boot, so
introduce a new parameter to bi_load in order to select whether BS
should be exited.
No functional change introduced in this patch, as all current users of
bi_load request BS to be exited. Further changes will make use of this
functionality.
Note the memory map is still appended to the kernel metadata, even
when it could be modified by further calls to the Boot Services, as it
will be used to detect if the kernel has been booted from UEFI.

This eliminates a lot of stat() calls that happen when lualoader renders the

ftype is nil if loader/loader.efi hasn't been updated yet, falling back to

There's a currently ad-hoc protocol to hand off the FreeBSD kernel
payload between the loader and the kernel itself when Xen is in the
middle of the picture. Such protocol wasn't very resilient to changes
to the loader itself, because it relied on moving metadata around to
package it using a certain layout. This has proven to be fragile, so
replace it with a more robust version.
The new protocol requires using a xen_header structure that will be
used to pass data between the FreeBSD loader and the FreeBSD kernel
when booting in dom0 mode. At the moment the only data conveyed is the
offset of the start of the module metadata relative to the start of the
module itself.
This is a slightly disruptive change since it also requires a change
to the kernel which is contained in this patch. In order to update
with this change the kernel must be updated before updating the
loader, as described in the handbook. Note this is only required when
booting a FreeBSD/Xen dom0. This change doesn't affect the normal
FreeBSD boot protocol.
This fixes booting FreeBSD/Xen in dom0 mode after
3630506b9d.

While loading kernel, we check if vt/vbe backend support is included in

this check with new kernel.

On i386, after 6c7a932d0b, the vbefb vt
driver was no longer detected by the loader, if any kernel module was
loaded after the kernel itself.
This was caused by the parse_vt_drv_set() function being called multiple
times, resetting the detection flag. (It was called multiple times,
becuase i386 .ko files are shared objects like the kernel proper, while
this is not the case on amd64.)
Fix this by skipping the set_vt_drv_set lookup if vbefb was already
detected.

efi, like the various ${MACHINE} directories, should have a dependency on
the enabled interpreters.
The general rule here is that any top-level directory that has a program at
any depth within that includes loader.mk should add ${INTERP_DEPENDS} added
to its dependencies so that the appropriate ficl/lua bits are ready before
they begin.
Note that the only directories in-tree that require it but will not get it
in a more appropriate manner are i386 (on amd64), efi, and userboot. i386
and userboot are handled explicitly in Makefile.amd64 where they are added
to S.yes.

lualoader was previously not processing \ as escapes; this commit fixes
that and does better error checking on the value as well.
Additionally, loader.conf had some odd restrictions on values that make
little sense. Previously, lines like:
kernel=foo
Would simply be discarded with a malformed line complaint you might not
see unless you disable beastie.
lualoader tries to process these as well as it can and manipulates the
environment, while forthloader did minimal processing and constructed a
`set` command to do the heavy lifting instead. The lua approach was
re-envisioned from building a `set` command so that we can appropriately
reset the environment when, for example, boot environments change.
Lift the previous restrictions to allow unquoted values on the right hand
side of an expression. Note that an unquoted value is effectively:
[A-Za-z0-9-][A-Za-z0-9-_.]*
This commit also stops trying to weirdly limit what it can handle in a
quoted value. Previously it only allowed spaces, alphanumeric, and
punctuation, which is kind of weird. Change it here to grab as much as it
can between two sets of quotes, then let processEnvVar() do the needful and
complain if it finds something malformed looking.
My extremely sophisticated test suite is as follows:
<<EOF
X_01_simple_string="simple"
X_02_escaped_string="s\imple"

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.
This fixes the positioning of the "Welcome to FreeBSD" heading, which was
misplaced after the recent update to Lua 5.4. The issue was previously
masked by a compatibility knob in Lua 5.3 that would cause float-tagged
numbers to render faithfully without the decimal component. Lua 5.4 dropped
that and ensures that it always prints a decimal component, even if it has
to append a ".0" to the value.
Standard division produces a "float", floor division (//) can be used to
guarantee an integer. Floating point operations have been completely ripped
out of the liblua compiled for the bootloader, so this is a nop. This is
decidedly better than trying to hack out the float tag entirely.

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.
