2024-04-27update/release: disable status checkingLeah Rowe
just to ensure that nothing goes wrong. we don't rely on the status variable for releases, because there is another variable, release, that target.cfg files declare, e.g. release="n" release="y" you can just omit the variable, because it defaults to y, so you only need declare it when it needs to be "n" Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-04-27allow disabling status checks during buildsLeah Rowe
export LBMK_STATUS=n if not set, the status checks and confirmation dialogs persist. if set to y they persist. if you set it to n, all checks are disabled, so e.g.: ./build roms all this would once again build all targets, regardless of status. this is if you want the old behaviour.

2024-04-26build/roms: report status when building imagesLeah Rowe
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" Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-04-25build/roms: add missing deletion of tmp fileLeah Rowe
the temporary rom per build was not being deleted after finishing the current target. this adds up in /tmp during large builds, when building for many targets. fix this! Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-04-24haswell: only provide NRI-based ROMs in releasesLeah Rowe
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. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-03-27allow users to specify number of build threadsLeah Rowe
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.

2024-03-27safer, simpler error handling in lbmkLeah Rowe
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.

2024-01-26update/trees: reset xtree/tree_depend before buildLeah Rowe
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. this patch fixes the issue. quite a simple problem, actually.

2024-01-23script/vendor/inject: remove erroneous checkLeah Rowe
the boarddir variable is only set *after* detect_board is run, and is in fact checked after that. this check, removed by this patch, is too early and causes lbmk to exit with error states. this patch fixes the error. the error was that lbmk was then searching for a file that is at an empty path.

2024-01-18GRUB: insert only 1 keymap per board, in cbfsLeah Rowe
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. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-01-12REMOVE MAINBOARD: lenovo x201Leah Rowe
with neutered ME, fan control fails. while there are ways to mitigate it, many users will not, and will likely see their system overheat, which is very dangerous. this bug (failed fan control on neutered ME) only affects arrandale machines such as lenovo x201. the newer machines are not affected by this. other arrandale machines will probably not be added to libreboot because of this, or they will be subject to further testing.

2024-01-10NEW MAINBOARD: HP EliteBook 820 G2Leah Rowe
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.
