2024-08-11vendor.sh: use readkconfig on inject tooLeah Rowe
same as the last change. we must avoid use of make variables, in sh specifically, when handling these configuration files. Signed-off-by: Leah Rowe <info@minifree.org>
2024-08-11vendor.sh: don't load entire coreboot configsLeah Rowe
instead, only grep for the entries required, such as Intel ME paths. some variables in coreboot configs use $(), which is used in *make*, on the coreboot build system, and there refers to variables. here, we are sourcing them from sh, which treats this as a mini subshell to run a command; for example CONFIG_FOO would be executed, which is bad. The current logic still theoretically has this problem, with this patch, but the entries we scan from the configs do not currently have variable names in the strings. So: filter out just what we need, into a temporary config, when scanning for vendor files in coreboot configs, and use the temporary config. This fixes a build error when compiling for e5520_6mb.

2024-07-28lib.sh: new function mk() to handle trees in bulkLeah Rowe
single-tree projects cannot be handled in bulk, e.g. ./mk -f project1 project2 project3 that is still the case, from the shell, but internally it is now possible: mk -f project1 project2 project3 mk() is a function that simply handles the given flag, and all projects specified. it does not handle cases without argument, for example you cannot do: mk -f arguments must be provided. it can be used internally, to simplify cases where multiple single-tree projects must be handled, but *also* allows multi-tree projects to be specified, without being able to actually handle trees within that multi-tree project; so for example, you can only specify coreboot, and then it would run on every coreboot tree.

same as the last change. make the main function a wrapper that dry-runs the real function. if the "dry" variable is blank, it executes. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-07-22rom.sh: fix buggy deletion of cbutilsLeah Rowe
when badhash=y, the utils should be deleted, but the check is deleting if badhash isn't n. if the hash check isn't being performed, then this will always be the case and the utils are always deleted. make it positively delete the file only if badhash=y, not when it isn't n. while this may not sound very different, it will prevent the utils being deleted and re-build endlessly in other cases, like when building release archives and running the inject --nuke mode on every image that gets built. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-22rom.sh: also add grub to seabios imagesLeah Rowe
we want multiple seagrub images made, with different keymaps, but we only want one non-seagrub image. however, we also want grub in the non-seagrub image. it just means that seabios is primarily what the user wants, and they might occasionally use grub, whereas the seagrub images are for people who primarily want grub but may occasionally access the seabios menu. right now, the seabios images really only contain seabios, but there's no harm in adding grub to them. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-22rom.sh: copy tmprom to TMPDIR for modificationLeah Rowe
don't rely on build/coreboot.rom staying in place, because sometimes it can get purged under certain conditions, due to idiosyncrasies in the coreboot build system, even when we don't explicitly clean it Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-22rom.sh: re-add seabios-only roms and grub keymapsLeah Rowe
this time, only handle multiple keymaps on seagrub images. for images where seabios is first but does not immediately load grub, whether grub is still available in flash, just do one image (US Qwerty) this still results in fewer images per target than Libreboot 20240612, but should prevent most users from being annoyed. i got a few people asking repeatedly, and i hadn't documented yet how to add keymap.gkb or how to remove bootorder, to get a different keymap or disable seagrub respectively. i anticipate that i'll get such questions a lot, even if i do document it, so i'm reversing that decision. it doesn't result in much extra code. the new design in lbmk makes this sort of thing much simpler.

2024-07-21include/rom.sh: use ccache when building corebootLeah Rowe
ccache now required, in build dependencies Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-19vendor.sh: don't use XBMK_CACHE for appdiraudit6Leah Rowe
the me_extract function prefixes it with PWD in some cases, but we can't predict where appdir will point to. the "app" directory is not intended to be a cache anyway, so it doesn't make sense to put it in the cache directory. it's essentially scratch memory. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-19put cachedir in environmental variableLeah Rowe
XBMK_CACHE is now used, instead of hardcoding cache/ this is exported initialised to cache/, if unset. this means you can set your own directory, and it means ./update release will use the same directory. this means bandwidth wastage is further avoided. Signed-off-by: Leah Rowe <leah@libreboot.org>

the || : condition should be used, whereas i just wrote : by mistake. this was done in a previous change. fix it now. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-18git.sh: fix lack of error exits on faultLeah Rowe
a previous change made it more redundant, falling back on old behaviour (direct downloading, not cached), but the way it's done means that the function never returns an error condition in practise. this patch fixes it. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17allow using coreboot's build system to add payloadLeah Rowe
lbmk must still define payloads, but specific configs may use coreboot's build system instead. you might use this to add your own config with, say, tianocore payload, using coreboot.git to build it, rather than using lbmk's choice of payloads. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17unify caching of files into cache/Leah Rowe
hash/ becomes cache/hash/ repo/ becomes cache/repo/ Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17unified cache file handling for vendorfile/subfileLeah Rowe
lib.sh download() is used by subfile handling in git.sh, e.g. crossgcc tarballs, and also the vendor scripts. vendor files are cached, but not subfiles for repos. cache both, under cache/file/, saved with the name equal to the checksum, so: cache/file/CHECKSUM also move vendorfiles/app/ to cache/app/ in this change. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17git.sh: remove previous tmprepo if args>5Leah Rowe
if doing a retry, the directory may still exist, which would make git clone yield an error response; the existing directory will have been the one that failed to reset, so let's delete it. the one deleted is not the cache (repo/PROJECT/), thus otherwise maintaining current behaviour. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17git.sh: try direct clone if cached git failsLeah Rowe
normally, a project is cached at repo/PROJECT/, and cloned from there to the final destination. errors lead to a calling of $err, but this will result in a return if done from inside a subshell, of non-zero value, so use this to re-try with a 6th argument when calling tmpclone(). in most cases, this fallback will never kick in, but it will kick in resetting or patching the cached clone fails; specifically, we are interested in the reset part. a given project name may change repositories in lbmk at a given time. if this happens, and the old one is cached, the overall result of this patch is that lbmk will fall back to the old behaviour, where git urls are tried directly, without caching.

2024-07-17trees: auto-delete+auto-rebuild if project changesLeah Rowe
actual source code is not scanned, but config directories are scanned. simply get the checksum of each file under config/ pertaining to a given project/tree, and also for the given target. coreboot utilities are also handled. if it changes, in any way, delete and re-build automatically. such deletions should probably still be done manually, as part of understanding the build system, but this change should make the build system much easier to use during development. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17git.sh: don't download to src/project/project/Leah Rowe
re-use repo/project/ this means that single- and multi-tree projects now have a unified cached git repo location, as per the new rules, thus saving on disk space usage. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-17git.sh: cache git downloads to repo/Leah Rowe
do it based on the URL, e.g. https://review.coreboot.org/coreboot becomes repo/coreboot the downside is if you have two projects with repo urls specifying the same string at the end, but this isn't the case at the moment and likely won't be the case, but it's a theoretical issue. this saves on bandwidth when downloading identical submodule repos between multiple trees within the same multi-tree project for example, coreboot 3rdparty/vboot is no longer downloaded more than once, instead cloned locally on subsequent downloads. if repo/DIR exists, git-pull is attempted, but errors do not result in a non-zero exit, by design.

2024-07-10trees: use wrapper for dry-running make commandsLeah Rowe
instead of using lots of if/else conditions, do that once and set a variable, dry, to : if not doing a dry run, the variable is empty. prefix this variable in places where you don't want a certain action to be performed, on dry runs. more specifically, : does *nothing* and always returns with zero status (success). this results in cleaner code, and a small sloccount reduction.

2024-07-10rom.sh: only before cbutils before corebootLeah Rowe
otherwise, due to the idiosyncratic nature of the coreboot build system, the coreboot.rom gets wiped out. cbutils is still handled by premake. ensure that payloads are only inserted just after running the coreboot make command. fixes a build issues introduced on 9020sff, previously unhandled.

2024-07-09trees: support -d (dry run) for custom build logicLeah Rowe
-d does the same as -b, except for actually building anything! in effect, it does the same as -f (fetch) except that the resulting variable assignments will not be recursive (as with -f). if -d is passed, configuration is still loaded, defconfig files are still cycled through, and more importantly: helper functions are still processed. the grub, serprog and coreboot helper functions have been modified to return early (zero status) if -d is passed. this behaviour will be used to integrate vendor.sh logic in with the trees script, for cases where the user wants to only handle vendor files. e.g.: ./update trees -b coreboot x230_12mb this would download the files as usual, build coreboot, with those files, and then build the payloads. but: ./update trees -d coreboot x230_12mb this would download the files, NOT build coreboot, and NOT build the payloads. this change increases the sloccount a bit, but i'm relying on the fact that the vendor.sh script already re-implements config handling wastefully; the plan is to only use trees. for now, simply stub the same ./vendor download command. there is one additional benefit to doing it this way: this method is *per-kconfig* rather than per-target. this way, one kconfig might specify a given vendor file that is not specified in the other. although the stub still simply handles this per target, it's done in premake, which means that the given .config file has been copied. this means that when i properly re-integrate the logic into script/trees, i'll be able to go for it per-kconfig. the utils command has been removed, e.g. ./update trees -b coreboot utils default the equivalent is now: ./update trees -d coreboot default this would technically download vendor files, but here we are specifying a target for which no kconfigs exist; a check is also in place, to avoid running the vendor file download logic if tree==target the overall effect of this change is that the trees script no longer contains any project-specific logic, except for the crossgcc build logic. it does include some config/data mkhelper files at the top, for serprog and coreboot, so that those variables defined in those files can be global, but another solution to mitigate that will also be implemented in a future commit. the purpose of this and other revisions (in the final push to complete lbmk audit 6 / cbmk audit 2) is to generalise as much logic as possible, removing various ugly hacks.

2024-07-07rom.sh: new file, to replace script/romsLeah Rowe
stub it from the trees script. the way it works now, there is less code in the build system. ./build roms this is no longer a thing ./build roms serprog this is also no longer a thing. instead, do: ./update trees -b coreboot targetnamehere ./update trees -b pico-serprog ./update trees -b stm32-vserprog the old commands still works, which causes the new commands to run coreboot roms now appear in elf/, not bin/, as before, but those images now contain payloads. NOTE: to contradict the above: ./build roms is no longer a thing, in that it's now deprecated, but backward compatibility is present for now. it will be removed in a future release. ./build roms list also still works! it will do: ./update trees -b coreboot list also: ./update trees -b grub list this is now possible too if a target "list" is provided, for multi-tree sources, the targets are shown. there is another difference: seagrub roms are now seagrub_, instead of seabios_withgrub. seabios-only roms are no longer provided, where grub is also enabled; only seagrub is used. the user can easily remove the bootorder file, if they want seabios to not try grub first.

2024-06-30trees, multi: download bare project *before* treesLeah Rowe
when downloading multi-tree projects, the rev can be reset to HEAD instead of the actual rev for a given target. this occurs when the bare repo (e.g. src/coreboot/coreboot) does not exist and has to be downloaded first. bare repository downloading does not rely on target.cfg, in this context, only pkg.cfg, but it uses the same variable names (e.g. "rev"). instead of using a separate variable name, thus increasing code complexity (which is the exact opposite of what i want to do), do the bare repository download first. this means that the git.sh script is much cleaner now, for multi-tree projects, in that it *only* copies the bare repo then runs git_prep; in that context, the bare repo is cloned directly by calling the relevant function from script/trees, which is the same behaviour as when cloning single-tree project sources. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-30trees: unified multi-tree configuration handlingLeah Rowe
the same function that loads configurations for single-tree projects has been merged with the function for multi-tree configs in git.sh, and that functionality has been removed from git.sh; now it is all unified in the trees script. as the saying goes: write one program to do one thing well. the purpose of git.sh is to download source code, but not to handle configuration files; the latter is meant to be handled by the trees script, which then calls into git.sh before running the build logic for that given project. additionally: the "seen" files are no longer handled, at all. the logic there was added ages ago, because at the time, i was considering whether to separate configuration into a new repository, so that users could more easily make their own configuration, so it was a guard against misconfiguration. however, that decision was canceled and we're always very careful not to introduce a loop; if a loop does occur, the worst that can possibly happen is you waste some CPU cycles. Instead, print (on standard output) what config file is being used, so the operator can see when an infinite loop occurs. ALSO: remove _setcfgarg in load_project_config() it was used to skip when a target.cfg file didn't exist, specifically on single-tree projects, but this is now handled using -f instead, on the while loop inside that function, so _setcfgarg is now a redundant variable.
