export LBMK_VERSION_TYPE=x
x can be: stable, unstable
in target.cfg files, specify:
status=x
x can be: stable, unstable, broken, untested
if unset, lbmk defaults to "unknown"
if LBMK_VERSION_TYPE is set, no confirmation is asked
if the given target matches what's set (but what's set
in that environmental variable can only be stable or
unstable)
if LBMK_RELEASE="y", no confirmation is asked, unless
the target is something other than stable/unstable
"unstable" means it works, but has a few non-breaking
bugs, e.g. broken s3 on dell e6400
whereas, if raminit regularly fails or it is so absolutely
unreliable as to be unusable, then the board should be
declared "broken"
untested means: it has not been tested
With this change, it should now be easier to track whether
a given board is tested, in preparation for releases. When
working on trees/boards, status can be set for targets.
Also: in the board directory, you can add a "warn.txt" file
which will display a message. For example, if a board has a
particular quirk to watch out for, write that there. The message
will be printed during the build process, to stdout.
If status is anything *other* than stable, or it is unstable
but LBMK_VERSION_TYPE is not set to "unstable", and not building
a release, a confirmation is passed.
If the board is not specified as stable or unstable, during
a release build, the build is skipped and the ROM is not
provided in that release; this is in *addition* to
release="n" or release="y" that can be set in target.cfg,
which will skip the release build for that target if "n"

release="n" is set in target.cfg on haswell build targets
that use mrc.bin
script/update/release exports LBMK_RELEASE="y"
script/build/roms skips building a given target if release="n"
in target.cfg *and* LBMK_RELEASE="y"
you could also do the export yourself before running ./build roms,
for example:
export LBMK_RELEASE="y"
./build roms all
This would skip these ROM images. The native haswell raminit is
now stable enough in my testing, that I wish to delete the MRC-based
targets. This is in line with Libreboot's Binary Blob Reduction Policy,
which states: if a blob can be avoided, it should be avoided.
The problem is that users often run the inject script in *lbmk* from
Git, instead of from the src release archive. I forsee some users
running this on modern lbmk with older release images. If the mrc-based
target isn't there, the user may use an NRI-based target name, and
think it works; they will insert without MRC. I foresaw this ages
ago, which is why Caleb and I ensured that the script checks hashes,
and hashes are included in releases.
Therefore: for the time being, keep the MRC-based configs in lbmk
but do not include images for them in releases. This can be done
indefinitely, but I'll probably remove those configs entirely at
some point.
On the following boards, Libreboot now will *only* provide NRI-based
ROM images for the following machines:
* Dell OptiPlex 9020 SFF
* Dell OptiPlex 9020 MT
* Lenovo ThinkPad T440p
* Lenovo ThinkPad W541/W540
I now recommend exclusive use of NRI-based images, on Haswell
hardware. It's stable enough in my testing, and now supports S3.

lbmk otherwise uses nproc to set the number of build threads,
in these places:
* generic make commands in script/update/trees
* crossgcc make command in script/update/trees
the -T0 option is also used in script/update/release, when running
tar.
with this change, you can do:
export LBMK_THREADS=x
where x is the number of threads. when you then run
lbmk, your chosen number of threads will override
the default. this may be useful on a host that does
not have a lot of memory.

in shell scripts, a function named the same as a program included in
the $PATH will override that program. for example, you could make a
function called ls() and this would override the standand "ls".
in lbmk, a part of it was first trying to run the "fail" command,
deferring to "err", because some scripts call fail() which does
some minor cleanup before calling err.
in most cases, fail() is not defined, and it's possible that the user
could have a program called "fail" in their $PATH, the behaviour of
which we could not determine, and it could have disastrous effects.
lbmk error handling has been re-engineered in such a way that the
err function is defined in a variable, which defaults to err_ which
calls err_, so defined under include/err.sh.
in functions that require cleanup prior to error handling, a fail()
function is still defined, and err is overridden, thus:
err="fail"
this change has made xx_() obsolete, so now only x_ is used. the x_
function is a wrapper that can be used to run a command and exit with
non-zero status (from lbmk) if the command fails. the xx_ command
did the same thing, but called fail() which would have called err();
now everything is $err
example:
rm -f "$filename" || err "could not delete file"
this would now be:
rm -f "$filename" || $err "could not delete file"
overriding of err= must be done *after* including err.sh. for
example:
err="fail"
. "include/err.sh"
^ this is wrong. instead, one must do:
. "include/err.sh"
err="fail"
this is because err is set as a global variable under err.sh
the new error handling is much cleaner, and safer. it also reduces
the chance of mistakes such as: calling err when you meant to
call fail. this is because the standard way is now to call $err,
so you set err="fail" at the top of the script and all is well.

in some cases, the build system was needlessly, and sometimes
erroneously, creating crossgcc symlinks, which then caused an
issue, namely:
in lbmk release builds, dell e6400 is build before fam15h boards,
and it sets xtree, but fam15h_rdimm doesn't, and later this would
cause fam15h_rdimm boards to use xtree="default" (because they don't
set xtree), causing the newer toolchain to be used on coreboot 4.11.

There is no need to add multiple keymap files, because
GRUB can load keymaps from CBFS. The current build logic
is designed to avoid building multiple GRUB binaries,
which are expensive computationally because each one
would then have to be compressed for each board.
This patch provides the best of both worlds: less space
used in flash like in the old lbmk design (1 keymap per
board), but retaining the current build speeds and therefore
not re-introducing the slowness of lbmk's previous GRUB
build logic.
The grub.cfg file has been modified, accordingly. It now
only loads a keymap.gkb file from CBFS, by default. It does
this, only if that file exists; if not, GRUB already defaults
to US Qwerty layout anyway.
ALSO: compress all keymap gkb files with xz -6
GRUB automatically decompresses files when accessed.
This results in about 2KB of flash space saved in CBFS.
Here is real-world data, showing the increased flash space:
< fallback/payload 0x3eb80 simple elf 548821 none
< keymap.cfg 0xc4bc0 raw 16 none
< (empty) 0xc4c00 null 11633316 none
---
> fallback/payload 0x3eb80 simple elf 546787 none
> keymap.gkb 0xc43c0 raw 344 none
> (empty) 0xc4540 null 11635044 none
This was taken by diffing the cbfstool "print" output,
both before and after. The *after* result is with this change.
11633316. In this example, 1728 bytes have been saved. Therefore,
with compression taken into account, this patch saves about 1.7KB
of space in CBFS.
This change means that lbmk can now scale to support hundreds
of keymaps, without increasing the amount of flash space used,
in each given image. Since the keymap files are compressed in
lbmk.git, in advance, we spend no additional time on compression
at build time. The resulting change in build speed in negligible.
Adding your own keymap.gkb file was already possible, for changing
the keymap in libreboot images, if you didn't want to change the
memdisk (and thus re-compile grub.elf). Now, this is the default
behaviour, and the only way to do it. It's much more efficient.
The original keymap files can be restored, by running unxz.

This is of Broadwell platform, one generation above Haswell.
Of note: this uses HP Sure Start. Although the flash is 16MB,
our CBFS section (and IFD configuration) assumes 12MB flash,
so the final 4MB will be left unflashed on installation,
after blanking the private flash. The coreboot documents have
more information about this.
Some minor design changes in lbmk were made, to accomodate
this port:
Support for extracting refcode binaries added (pulled from
Google recovery images). The refcode file is an ELF that
initialises the MRC and the PCH. It is also responsible for
enabling or disabling the Intel GbE device, where Google
does not enable it, but lbmk modifies it per the instructions
on the coreboot documentation, so as to enable Intel GbE.
Google's recovery image stores the refcode as a stage file,
but coreboot changed the format (for CBFS files) after 4.13
so coreboot 4.13's cbfstool is used to extract refcode. This
realisation made me also change the script logic to use a
cbfstool and ifdtool version matching the coreboot tree, for
all parts of lbmk, whereas lbmk previously used only the
default tree for cbfstool/ifdtool, on insertion and deletion
of vendor files - it was 81dc20e744 that broke extraction of
refcode on google's recovery images, where google used an older
version of cbfstool to insert the files in their coreboot ROMs.
A further backported patch has been added, copying coreboot
revision f22f408956 which is a build fix from Nico Huber.
Iru Cai submitted an ACPI bugfix after the revision lbmk
currently uses, for coreboot/default, and this fix is
needed for rebooting to work on Linux 6.1 or higher. This
patch has been backported to lbmk, while it still uses the
same October 2023 revision of coreboot.
Broadwell MRC is inserted at the same offset as Haswell,
so I didn't need to tweak that.

it is no longer hardcoded just to be handled for uefiextract.
it is now defined as cmakedir in target.cfg, for a single or

tree, and has to be defined per tree
the way it works is: as per cmakelist, a project will define
which directory is to be built, and it will then generate
a makefile in the main source tree (the build tree in cmake
language, where the main CMakeLists.txt file exists)
when the makefile has been generated, the project is then treated
like any other project. the way cmake works, if a makefile has
already been generated by it, in a given directory, running it
again will fail and not affect anything; if it fails but the
makefile doesn't exist, then something is wrong, but if the
makefile does exist, then it's all fine and nothing happens

at present, lbmk can remove microcode updates on images for
a given target, if the target specifies
microcode_required="n" in target.cfg
lbmk then provides images with microcode, and images without,
in a given release. although the user can also remove them
manually, this just makes it a bit more convenient, for those
users who do wish to run without the updates. this functionality
is provided only on those platforms where no-microcode is tested.
well, this behaviour implements a compromise on libreboot policy,
which is to always include microcode updates by default. see:
Binary Blob Reduction Policy
the *canoeboot* project now exists, developed in parallel with
libreboot, and it ships without microcode updates, on the same
targets where lbmk also handled this.
running without microcode updates is foolish, and should not
be encouraged. clean up lbmk by not providing this kludge.
the libreboot documentation will be updated, telling such users
to try canoeboot instead, or to remove the update from a given
libreboot rom - this is still possible, and mitigations such as
PECI disablement on GM45 are still in place (and will be kept),
so that this continues to work well.

recent build system simplifications have enabled
this change, thus:
./build fw coreboot -> ./build roms
./build fw grub -> ./build grub
./build fw serprog -> ./build serprog
./update project release -> ./update release
./update project trees -> ./update trees
./update vendor download -> ./vendor download
./update vendor inject -> ./vendor inject

are not meaningfully used.

We don't really need a custom coreboot tree for Chromebooks. I had added
one, because at a cursory glance to the available config/coreboot/board
subdirectories I had the impression that I should. But upstreams have
one tree for every board and I think we should move towards that too.
Move the one important BL31 makefile patch into the default coreboot
patches, update the gru boards' configs by running savedefconfig in the
cros tree and then running olddefconfig in the default tree.

Add an "-s" flag for "make savedefconfig", "-l" for "make olddefconfig"
and "-n" for "make nconfig" to the update script. The first two are
mainly useful for U-Boot, to compare our configs to the upstream
defconfigs and stay in sync with any upstream changes. The latter is
because the ncurses one has a nice "Symbol Search" that can point out
the menu entry for a config symbol we know.

The "u-boot.bin" file generated by U-Boot builds is a raw binary. When
adding payloads to a CBFS, we need to use ELF files with add-payload
or manually pass the entry point and load address of the payload binary
with add-flat-binary.
We primarily use the "u-boot.elf" which gets build with the REMAKE_ELF
option, as it also has the necessary device-tree binary that U-Boot
usually needs to work. When the option is not set (e.g. for QEMU), we
need to use the "u-boot" file which is an ELF.

i wasn't getting the very first line of tar --version,
so it wasn't doing the check properly.

for reliability, don't bother using versiondate anymore:
set a *fixed* date, and fixed timezone, to ensure
that it works reliably for reproducible tarball creation.

This way, the handling of configs is unified into one

e.g. src/coreboot/coreboot must not appear in a release,
because we instead have directories like
src/coreboot/default or src/coreboot/cros
lbmk resets src/coreboot/coreboot to HEAD, but then resets
revisions properly in copies of it
therefore, for reproducibility, we must not include
src/coreboot/coreboot, src/u-boot/u-boot or
src/seabios/seabios into libreboot releases

with --mtime, files added to the archive can be set
to a static date (in this case, the unix epoch)
the one used here is derived from git commit dates,
and it is static; if not being handled in lbmk.git,
the versiondate file never changes
this is the first patch in a series of patches designed
to bring about reproducible builds in libreboot
a solution will need to be found, for non-GNU tar
implementations, because they did not have an
equivalent option according to their manpages.
for example, BSD tar implementations.
perhaps i could systematically go around changing
file dates, on each file, as a fallback behaviour?

this way, the src tarball is guaranteed to be clean.
the downside is that lbmk itself does not currently
handle crossgcc downloads, and there may be some
stragglers such as third party modules automatically
downloaded by certain codebases that libreboot uses.
this will have to be audited later (and it will be).

Riku's mSATA patch for HP8300USDT was merged upstream, so the

coreboot closely matches upstream, whose current release
is version 1.2 from 2018, and coreboot has not changed it
in any meaningful way.
the upstream did add patches since, but they are documentation
patches only.
this means: we do not need to use the upstream version

some users reported build errors. technically, there's
nothing wrong with lbmk but it relies on hostcc, and
hostcc is hit or miss when it comes to cross compiling
32-bit, depending on the build system of whatever project.
lbmk needs to handle cross compilation. for now, i'm just
disabling memtest86plus on non-64-bit hosts.

The logic has been re-written, where source archives are
concerned. This clones the current repository, and starts
a new build from scratch. A custom release directory is
possible, by passing -d
This eliminates a step during build-testing, saving hours
of time, because it builds the release archive *inside* the
release archive, with git files removed, thus replicating
the same setup that the user would have.
This also makes everything a bit more consistent, because
it's guaranteed that a release archive will always have
the same files; previously, the release build script would
only copy what was already built, without building anything.
Now, this script builds everything itself.
The script also builds serprog images, not just coreboot.
Usage:
./update project release
If -d is not passed, release/ is used inside lbmk.
Otherwise, you could do:
./update project release -d /path/to/directory
If the directory exists, this script will exit (error).
Other minor fixes: build/fw/coreboot: make version in
coreboot-version (file) not contain hyphens, to work
around a quirk in coreboot's build system when not building
on regular libreboot releases. this quirk only appears
when lbmk is not being compiled under git.
The other main benefit of this change is that the new
script will probably require a lot less maintenance.

the script used to be called once per target, now it
handles every target. the grub background image wasn't
being set, so if it changed at build time, it would
stay changed.
keep the default in place for each run, while still
allowing target.cfg files to change it per target.

Just one script.
Just one!
Well, two, but the 2nd one already existed:
logic in update/project/trees and
update/project/repo was merged into
include/git.sh and update/project/build
was renamed to update/project/trees; an -f
option was added, which calls the functions
under git.sh
so git clones are now handled by the main build
script (for handling makefiles and defconfigs)
but the logic there is a stub, where git.sh
does all the actual heavy lifting
this cuts the file count down by two, and reduces
sloccount a reasonable amount because much of
the logic already exists in the build script, when
it comes to handling targets. git.sh was adjusted
to integrate with this, rather than act standalone

The benefit now is that it can be cleaned. E.g.
./update project build -b coreboot utils
./update project build -b coreboot utils default
./update project build -c coreboot utils
./update project build -c coreboot utils default
the update/project/build script checks when arguments
are provided after the project name. if the first one
is "utils", then it acts in the same way as the old
build/coreboot/util script

it's buggy. "./build fw coreboot" was made to work,
but it caused lots of unknown issues when mixing other
args
the old way wasn't broken. now, once again, you must
pass the "all" argument. e.g.:
./build fw coreboot all
Also, the confirmation messages at the end are a bit

if a rom image fails to compile, then it will also
exit with error status, but sometimes you can pass
argument "cros" or "default", and it would not give
you rom images due to no target.cfg files, but these
are also ignored because of that.
this restores the same behaviour that existed before,
for this final error check.
