2024-06-15trees: simplify copy_elf()Leah Rowe
Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-15trees: remove unnecessary check in copy_elfLeah Rowe
we don't need to check whether this variable is set, because checking an empty path will also cause the same return in the next line. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-15grub: insert background in memdisk insteadLeah Rowe
the background is only a few kb. the whole rationale before was to limit the space used in memdisk, but this decision was made when the background was much bigger; it has since been optimised greatly, and the grub modules were heavily reduce, so it should be safe. grub's memdisk breaks when you add too much data to it. as part of simplifying the rest of lbmk, this change removes some more bloat from the rest of lbmk. handling this in the memdisk is much simpler than handling it with cbfstool.

2024-06-15roms: unify all add-payload commandsLeah Rowe
add a generic function that can insert payloads with lzma compression, or raw files without compression Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-15roms: don't add grub keymaps at allLeah Rowe
if not inserted, the default keymap is usqwerty. don't waste ssd write cycles copying so many images, or cpu time compressing so many. the user can simply add a keymap.gkb file to cbfs and it will work fine. this will be documented in the next release. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-14roms: merge handle_coreboot_target into main()Leah Rowe
rely on return status per each of the three main rom functions, to then update the "targets" variable. use this as the basis to determine which targets were built, during final confirmation when the script exits. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-06-14roms: remove redundant check on grub_scan_diskLeah Rowe
the current validation check is extremely over-engineered, because the user override is no longer available and we're always very careful in how we modify target.cfg per board. remove the redundant code. trust that target.cfg is correct. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-14roms: remove dangerous runtime p/s/d optionsLeah Rowe
p = payload s = grub_scan_disk d = displaymode setting the payload is no longer safe, due to issue 216 and similar issues that might pop up in the future; it's best left only to target.cfg, per board, so that we know what config is safe/tested. don't let the user override it. scandisk isn't safe to override because the given machine may not have the type of device that the user specifies displaymode is actually ok to set, because it simply whitelists what configs pre-existing to actually use, but it's bloat basically, the rule is this: don't make it easy for the user to brick their hardware. make it harder instead. a user wily enough to go modifying their payload will probably have read docs/maintain/ anyway and knows how to edit target.cfg if they want another board configuration.

2024-06-09minor code cleanup in the build systemLeah Rowe
Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-09re-add ability to use cbfs grub.cfg as defaultLeah Rowe
i removed this before, when making grub multi-tree, because the design i used in an earlier version of the patch actually added the grub.elf generation to grub source itself, but then i decided to hack around the grub build system from lbmk/cbmk instead re-add this functionality, so that users can easily insert their own custom grub.cfg into cbfs without needing to re-build their image. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-09trees: exit with error if project undefinedLeah Rowe
i was originally looser about this, because i also wanted the trees script to generically run "make" from any directory, but this behaviour was error-prone and it is no longer used in the build system. disable it, in the interest of stability. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-09add crossgcc tarballs to config/submodules/Leah Rowe
support redundant downloads, and enable inclusion of these tarballs inside release archives, for offline builds. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07trees: simplified copy_elf() handlingLeah Rowe
don't create elfdir, create dest_dir, which is elfdir plus the location within it only create dest_dir within copy_elf, which is only called if actually compiling the code this avoids creating empty elf directories, and it generally cleans up all handling, unifying the handling of directories into a single function, namely copy_elf() which already exists Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07git.sh: download "depend" projects *before*Leah Rowe
don't do it after, because that means the main project is saved under src/ before we know whether the subrepo was downloaded. the "depend" variable (in config/git/) is no longer used for projects that go in subdirectories of a parent; now, we use config/submodules/ for this type of dependency. download the "depend" projects (as per config/git/) first. this way, if they fail, the main one will fail, but if they succeed and main fails, you can just run the main download again and it won't fail. this fixes a bug where, depending on how you download a set of projects and depending on the order which you do so, a given project can become un-downloadable on current design, because git will complain that a directory already exists. this fix is done not only in code (by this commit), but by prior configuration changes.

2024-06-07trees: don't check empty path in copy_elf()Leah Rowe
it could lead to some whackiness later on Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07trees: fix build issue caused by bad elf checkLeah Rowe
we're not checking for bad elfs, but the check itself was bad due to a quirk in how sh works. really, really obscure bug. fixed now! if the given directory didn't actually exist, or there were no files in it, it'd be searching for the file named "*" which is obviously wrong Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07trees: fix listfile check in copy_elf()Leah Rowe
don't check that the variable is empty check that the file itself exists or not this should fix the recent build issues Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07trees: don't say check elf/ if build.list missingLeah Rowe
(on single tree projects. this complements the last patch) Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07trees: don't do elfcheck if build.list missingLeah Rowe
otherwise, some checks are done too soon, and nothing gets built. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06trees: unified coreboot makeargsLeah Rowe
in particular, the coreboot build system may auto-download submodules when building cbfstool; vboot for instance. we do not want such unpredictable behaviour, so now we use UPDATED_SUBMODULES=1 when building coreboot utilities. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06trees: use multiple threads to build cbutilsLeah Rowe
Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06move handle_coreboot_utils to script/treesLeah Rowe
it doesn't really make sense placed in lib.sh, because it's only called from script/trees Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06put coreboot utils in elf/, not cbutils/Leah Rowe
one directory per util, under elf/ e.g. elf/cbfstool/ further split by tree name, e.g.: elf/cbfstool/default/ elf/cbfstool/foo/ Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06trees: skip single-tree build if a build existsLeah Rowe
this replicates the same behaviour as multi-tree builds, checking for files inside the relevant elf/ directory Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06use correct memtest86plus path in script/romsLeah Rowe

2024-06-06trees: handle build-test on multi-tree projectsLeah Rowe
for example, now flashprog binaries could be placed in the elf/ directory, under elf/flashprog/ Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06move cfgsdir/datadir variables to lib.shLeah Rowe
it's also used from script/roms, in addition to trees move these variables to a common file used everywhere Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06handle build.list from config/data/, not config/Leah Rowe
certain code checks for build.list, to skip it, for example in items() we already use config/data/grub to store grub config data that applied to all trees create these directories too: config/data/coreboot config/data/u-boot config/data/seabios move the respective build.list files in here, and also to config/data/grub now multi-tree projects contain, per directory, just the target.cfg file and the patches directory. this is much cleaner, because some of the logic can be simplified more Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06don't use build.list to detect multi-tree projectsLeah Rowe
instead, check for the presence of target.cfg files not in config/project/ but config/project/tree/ the way this check is done, it merely returns 1 if config/project/*/target.cfg is detected, and returns 0 in all other cases, even if config/project/target.cfg exists that way, if the maintainer accidentally adds a target.cfg in the main directory, the given multi-tree project will not break Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-03better help text on invalid commandsLeah Rowe
adding help again is a bad idea. code should never document itself; that's what documentation is for. so, make the code do a better job telling the user where to find documentation. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-02make GRUB multi-tree and re-add xhci patchesLeah Rowe
Re-add xHCI only on haswell and broadwell machines, where they are needed. Otherwise, keep the same GRUB code. The xHCI patches were removed because they caused issues on Sandybridge-based Dell Latitude laptops. See: https://codeberg.org/libreboot/lbmk/issues/216 The issue was not reported elsewhere, including on the Haswell/Broadwell hardware where they are needed, but the build system could only build one version of GRUB. The older machines do not need xHCI patches, because they either do not have xHCI patches, or work (in GRUB) because they're in EHCI mode when running the payload. So, the problem is that we need the xHCI patches for GRUB on Haswell/Broadwell hardware, but the patches break Sandybridge hardware, and we only had the one build of GRUB. To mitigate this problem, the build system now supports building multiple revisions of GRUB, with different patches, and each given coreboot target can say which GRUB tree to use by setting this in target.cfg: grubtree="xhci" In the above example, the "xhci" tree would be used. Some generic GRUB config has been moved to config/data/grub/ and config/grub/ now looks like config/coreboot/ - also, the grub.cfg file (named "payload" in each tree) is copied to the GRUB source tree as ".config", then added to GRUB's memdisk in the same way, as grub.cfg. Several other design changes had to be made because of this: * grub.cfg in memdisk no longer automatically jumps to one in CBFS, but now shows a menuentry for it if available * Certain commands in script/trees are disabled for GRUB, such as *config make commands. * gnulib is now defined in config/submodule/grub/, instead of config/git/grub - and this mitigates an existing bug where downloading gnulib first would make grub no longer possible to download in lbmk. The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF, Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should work again in GRUB. The GRUB payload has been re-enabled on HP EliteBook 820 G2. This change will enable per-board GRUB optimisation in the future. For example, we hardcode what partitions and LVMs GRUB scans because * is slow on ICH7-based machines, due to GRUB's design. On other machines, * is reasonably fast, for automatically enumerating the list of devices for boot. Use of * (and other wildcards) could enable our GRUB payload to automatically boot more distros, with minimal fuss. This can be done at a later date, in subsequent revisions.

2024-05-28roms: allow user override of grub_scan_diskLeah Rowe
this effectively lets you change the boot order. example: ./build roms -s "nvme ata" t1650_12mb the above example would set: grub_scan_disk="nvme ata" another example: ./build roms -s nvme t1650_12mb this would set: grub_scan_disk="nvme" this overrides what's set in target.cfg for the given target. useful for quick reconfiguration if building from source Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-28trees: use CPUS=x on regular coreboot makeLeah Rowe

2024-05-27grub.cfg: use grub_scan_disk to set boot orderLeah Rowe
Previously, grub_scan_disk could set ata, ahci or "both", which would make both be tried (ahci first). This worked when we only dealt with ata and ahci devices, but now we support nvme devices so the logic is inherently flawed. Instead, use grub_scan_disk to store the boot order, e.g.: grub_scan_disk="ahci nvme ata" grub_scan_disk="nvme ata" In the first example, it would make GRUB scan ahci first, then nvme and then ata. In the secontd example, it would make GRUB scan nvme first, and then ata. If "both" is set, or anything other than ahci/ata/nvme, grub_scan_disk is now changed to "nvme ahci ata". Actual grub_scan_disk entries in target.cfg files will now be modified, to match each machine. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-05-25trees: reset makeargs per target/projectLeah Rowe
it wasn't being reset before. when coreboot is being built, i add to makeargs every time. if multiple targets are being built, the make command would end up looking something like: make -C src/coreboot/default UPDATED_SUBMODULES=1 \ UPDATED_SUBMODULES=1 (the parameter would be printed twice) of course, this doesn't check whether that parameter is added already in target.cfg for a given target, but that's ok because i won't add that one in target.cfg i baked it into the code, only when handling coreboot, because that was easier than either putting it in makeargs for every coreboot target.cfg, or again modifying the code to handle that; the current solution is the cleanest.
