"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.
By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.
bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.
To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).
At this time, only lua loader is updated.

In D12421, the ability to compile stand/ in little-endian was added, with the
intention to extend loader.kboot to run in Petitboot.
However, no further work was done, as the kernel then gained self-execution
capabilities as Petitboot was taught to load FreeBSD kernels directly.
The FreeBSD installer on powerpc64 (on POWER8 and POWER9) uses
/boot/etc/kboot.conf instead of loader.
As this option does nothing but cause stand/ to be miscompiled and actively
causes confusion, remove it.
(I have a functioning petitboot loader in my local tree, however, it turned
out to be quite inconvient to use due to the current petitboot plugin design

Some external code requires a specific set of include paths to work
properly since it emulates the typical environment the code is used
in. Enable this by creating a CFLAGS_EARLY.file variable that can be
used to build this stack. Otherwise the include stack we build for
stand programs may get in the way. Code that uses this feature has to
tolerate the normal stack of inclues being last on the list (and
presumably unused), though.
Generally, it it should only be used for the specific include
directories. Defines and that sort of thing should be done in the
normal CFLAGS variable. There is a global CFLAGS_EARY hook as well for
everything in a Makefile.
Please note that neither zstd nor encryption is

This is a change in preparation for stopping to use lorder.sh (D26044) and

Some time after r338418, I believe with -Os/-Oz -ffunction-sections

since it used bootprog_interp to determine what flavor of userboot it was.

working and I had worked up some potential solutions to use the variable
that involved printing it out. My vague recollection is that this was
rejected, and I forgot to explore the alternatives; I cannot find records of
this discussion anymore.
Fast forward to present day, Andrew reported that it was non-functional and
offered (effectively) this patch (sans comment) to stop the compiler from
optimizing it out by assigning it to a volatile variable. This removes
concerns about user-facing change while retaining the interpreter marker.
Furthermore, it could certainly be uglier.

The new and much improved interface, readConf, is much less of a hack;

subsequent loader_conf_files from there, and read-conf will also use it.
This improvement submitted by Olivier (cited below), loader_conf_files

This new table should be used for transient values that don't need to end up
in the loader environment. Generally, these will be things that are internal
details that really aren't needed or interesting outside of the config
module (e.g. if we changed how ${module}_* directives work, they might use
this instead).
To start, populate it with loader_conf_files. Any specific value of
loader_conf_files isn't all that interesting; if we're going to export it,
we should really instead export a loader_conf_files that indicates all of
the configuration files we processed. This will be used to reduce
bookkeeping overhead in a future commit that cleans up readConfFiles.
A future change in lualoader may take some liberties with the
loader_conf_files in the name of efficiency; namely, it may start omitting
it from the loader environment entirely so that it doesn't need to worry
about maintaining any specific value.
This variable has historically been incredibly volatile anyways, as it may
get set to completely different values in any given configuration file to
trigger a load of more files.
Document now that we may not maintain it in the future, but perhaps we'll
reserve the right to change our minds and eventually formally export all of
the loader configuration files that were read using this variable.

Some things (e.g. arbitrary MAC address generation) may use the hostuuid as
a factor in early boot, so providing a way to read /etc/hostid (if it's
available) and using it before userland starts up is desirable. The code is
written such that the preload doesn't *have* to be /etc/hostid, thus not
assuming that there will be newline at the end of the buffer or even the
exact shape of the newline. White trailing whitespace/non-printables
trimmed, the result will be validated as a valid uuid before it's used for
early boot purposes.
The preload can be turned off with hostuuid_load="NO" in /boot/loader.conf,
just as other preloads; it's worth noting that this is a 37-byte file, the
overhead is believed to be generally minimal.
It doesn't seem necessary at this time to be concerned with kern.hostid.

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.
For doing an install via loader, avoiding the need to rewind
large files is critical.
This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.

LLD 10.0.0 changed the behavior of the -Ttext option, so that using
-Ttext=0x0 now causes linking of the loaders to fail with:
ld: error: output file too large: 18446744073707016908 bytes
I reported this in https://bugs.llvm.org/show_bug.cgi?id=44715, and
initially reverted the upstream change in r357259 to work around it.
However, after some discussion with Fangrui Song in the upstream ticket,
I think we can classify this as an unfortunate interaction between using
-Ttext=0 in combination with --no-rosegment. (We added the latter
in r332090, because btxld does not correctly handle input with more
than 2 PT_LOAD segments.)
Fangrui suggested to use a linker script instead, and Warner was already
attempting this in r305353, but had to revert it due to "crypto-using
boot problems" (not sure what those were :).
This review updates the stand/i386/boot.ldscript to handle more
sections, inserts some symbols like _edata and such that we use in
libsa, and also discards any .interp section.
It uses ORG which is defined on the linker command line using
--defsym ORG=value to set the start of all the sections.

Before this change, LLD10 was creating several extra PT_LOAD sections,
which OFW does not understand.
Like we do for the kernel already, specify the program headers manually.
Additionally, to work around a crash in our base ld.bfd, we need to
actually assign something to the output section. LLD does not need this.
One side effect of this change is the removal of the GNU_STACK header.
This is more correct, since we are using a statically-allocated stack and
RWX mappings across the board this early in boot.

smbios used to be an i386 only kinda weird quirk to the x86
architecture. But UEFI picked it up, dusted it off and now it's many
other locations. Make it base technology by moving it to libsa and
fixing up the compliation. The code has issues with unaligned access
still, but that will be addressed in a followup commit.

Create a ptov() function. It's basically the same as the btx PTOV
macro, but works everywhere. smbios needs this to translate addresses,
but the translation differs between BIOS booting and EFI booting. Make
it a function so one smbios.o can be used everywhere. Provide
definitions for it in the two loaders affected.

We still need to set the hooks to prevent improper manipulations thereafter
at the loader prompt, but as it is we're actively preventing loaddev from
being set correctly in some circumstances (ZFS in particular) and doing more
work than needed with currdev -- that hook in particular validates it as a
correct device, which we can assume isn't needed in this context.

If we hit an error at this level, we are almost certainly not in any kind
of sane state where autoboot can do the right thing. Instead of letting it
try and probably failing, disable autoboot so they immediately get kicked
into a loader prompt for manual remediation/diagnosis.

vdev_read_pad2() does read VDEV_PAD_SIZE of data, and will copy size bytes
of it, hence, we need buffer of VDEV_PAD_SIZE bytes.
Issue introduced in r357497.
Reported by: se
CD boot is broken for some systems since bioscd and biosdisk merge. The issue is that we can not use anything else than int 13 ah=0x4b to query cd information.
The patch does restore the same probe as was originally used in bioscd.c. Additionally extra buffer padding is used to avoid memory corruption caused by some systems.

This may be used for the local module to hook in and load any additional
modules that it wants, since it can't modify the modules table internal to
config. We may consider adding API to do so at a later time, but I suspect
it will be more complicated to use with little return.
status is captured but ignored for the purpose of loading the hook. status
will be false if *any* module failed to load, but we typically don't let
that halt the boot so there's no reason to let it halt hooks. Some vendors
or setups may have expected fails that would be actively thwarted by
checking it.
We may, at a later date, consider adding an API for letting non-config
modules check which modules have successfully (or not) loaded in case an
unexpected failure *should* halt whatever they are doing.

The major problem with the current ordering is that loader.conf may contain
all of the magic we need to actually setup the console, so loading local.lua
prior to that can make it excessively difficult and annoying to debug
(whoops, sorry Ravi & Warner).
The new ordering has some implications, but I suspect they are a non-issue.
The first is that it's no longer possible for the local module to inject any
logic prior to loading config -- I suspect no one has relied on this. The
second implication is that the config.loaded hook is now useless, as the
local module will always be included after that hook would have fired.
For config.loaded, I will opt to leave it in, just in case we add an early
point for local lua to get injected or in case one wants to schedule some
deferred logic in a custom loader.lua. The overhead of having it if no hooks
will be invoked is relatively minimal.

As a new x86 CPU vendor, Chengdu Haiguang IC Design Co., Ltd (Hygon)
is a joint venture between AMD and Haiguang Information Technology Co.,
Ltd., aims at providing x86 processors for China server market.
The first generation Hygon processor(Dhyana) shares most architecture
with AMD's family 17h, but with different CPU vendor ID("HygonGenuine")
and PCI vendor ID(0x1d94) and family series number 18h(Hygon negotiated
with AMD to confirm that only Hygon use family 18h).
To enable Hygon Dhyana support in FreeBSD, add new definitions
HYGON_VENDOR_ID("HygonGenuine") and X86_VENDOR_HYGON(0x1d94) to identify
Hygon Dhyana CPU.
Initialize the CPU features(topology, local APIC ext, MSI, TSC, hwpstate,
MCA, DEBUG_CTL, etc) for amd64 and i386 mode by sharing the code path of
AMD family 17h.
The changes have been applied on FreeBSD 13.0-CURRENT and tested
successfully on Hygon Dhyana processor.

Due to the way u-boot for 32-bit powerpc is compiled, the interrupt code
assumes that the GOT pointer (r30) on u-boot is always intact.
When making syscalls to u-boot, ensure that we have restored r30 like we
found it before we enable interrupts to prevent u-boot from crashing if a
timer interrupt was pending.
This fixes ubldr on e500 qemu (assuming you have recompiled qemu's u-boot
with API support!)
