2024-08-09coreboot/dell: merge into coreboot/defaultLeah Rowe
The libgfxinit patch and other patches e.g. DDR2 fix, are now provided in coreboot/default. The Latitude E6400 is now using the newer coreboot revision from late July 2024. Some other configs had to change because of this, relating to the new way that Nicholas handles timing on LVDS displays with the E6400 port; a default 96MHz clock is still used for pixel reference clock, overridden with a value of 100MHz on other GM45 machines, where 96MHz was previously hardcoded.

2024-08-09coreboot/default: Update to 97bc693ab (2024-07-29)Leah Rowe
Several patches are now merged upstream and no longer needed in lbmk, such as the HP EliteBook 8560w patch, and related patches. Some patches were changed, for example the Dell Latitude ivb/snb laptops are now variants in coreboot, instead of being individual ports; now they re-use the same base code. This this, the corresponding files under config/submodules have changed, for things like 3rdparty submodules e.g. libgfxinit, and tarballs e.g. crossgcc. This is long overdue, and will enable more boards to be added. This newer revision will be used in the next release, and some follow-up patches will merge these trees into default: * coreboot/haswell * coreboot/dell Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-22roms: only support SeaBIOS/SeaGRUB on x86Leah Rowe
Never, ever build images where GRUB is the primary payload. These options have been removed from target.cfg handling: * seabios_withgrub * grub_withseabios The "payload_grub" variable now does the same thing as the old "seabios_withgrub" variable, if set. The "grubonly" configuration is retained, and enabled by default when SeaGRUB is enabled (non-grubonly also available). Due to lbmk issue #216, it is no longer Libreboot policy to make GRUB the primary payload on any board. GRUB's sheer size and complexity, plus the large number of memory corruption issues similar to it that *have* been fixed over the years, tells me that GRUB is a liability when it is the primary payload. SeaBIOS is a much safer payload to run as primary, on x86, due to its smaller size and much more conservative development; it is simply far less likely to break. If GRUB breaks in the future, the user's machine is not bricked. This is because SeaBIOS is the default payload. Since I no longer wish to ever provide GRUB as a primary payload, supporting it in lbmk adds needless bloat that will later probably break anyway due to lack of testing, so let's just assume SeaGRUB in all cases where the user wants to use a GRUB payload. You can mitigate potential security issues with SeaBIOS by disabling option ROM execution, which can be done at runtime by inserting integers into CBFS. The SeaBIOS documentation says how to do this. Libreboot's GRUB hardening guide still says how to add a bootorder file in CBFS, making SeaBIOS only load GRUB from CBFS, and nothing else. This, combined with the disablement of option ROM execution (if using Intel graphics), pretty much provides the same security benefits as GRUB-as-primary, for example when setting a GRUB password and GPG checks, with encrypted /boot as in the hardening guide.

2024-05-27coreboot: only run GRUB as a secondary payloadLeah Rowe
See: https://codeberg.org/libreboot/lbmk/issues/216 Almost all users will be OK running GRUB, but a minority of users have experienced a fatal error pertaining to grub_free() or grub_realloc() (as my investigation of GRUB sources reveal when grepping the error reported in the link above). We don't yet know what the bug is, only that the error occurs, leading to an effective brick if the user has GRUB as their primary payload. So far, it has only been reported on some Intel SandyBridge-based Dell Latitudes in Libreboot, but we can't be too sure. The user reported that memtest86+ passes just fine, and SeaBIOS works; BIOS GRUB also works, which means that the bug is likely only in an area of GRUB that runs specifically on the coreboot payload, so it's probably a driver in GRUB when running on the metal rather than BIOS/UEFI. The build system supports a configuration whereby SeaBIOS is the primary payload, but GRUB is available in the SeaBIOS boot select menu, and an additional configuration is available where GRUB is what SeaBIOS executes first (while still providing boot select); both of these are now the *only* configurations available, on all x86 targets except QEMU. The QEMU target is fine because if the bug occurs there, you can just close QEMU and try a different image. Even after this bug is later identified and fixed, the GRUB source code is vastly over-engineered and there are likely many more such bugs. SeaBIOS is a reliable payload; the code is small and robust. Remember always: Code equals bugs Therefore, this configuration change is likely going to be permanent. This will apply in the next release. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-11remove all status checks. only handle release.Leah Rowe
the release variable is all we need, turning a target on or off for a given release. the status checks were prone to bugs, and unnecessary; it also broke certain benchmark scripts. it's better to keep the lbmk logic simpler. board status will be moved to the documentation instead.

2024-05-03remove x220edp/x230edp (keep regular x220/x230)Leah Rowe
nitrocaster boards are hard to find nowadays and i'm not comfortable supporting the knockoff chinese gear; quality varies greatly, and i can't know how reliable they are. nitrocaster has been out of business so it's just not viable to support this mod anymore. in fact, keeping the eDP-based targets is a liability to libreboot. regular x220/x230 (non-eDP-modded) are retained. the eDP modkit from nitrocaster let you use eDP screens instead of lvds, on thinkpad x220 and x230, letting you use higher resolution screens. older lbmk revs can still be used, if you happen to come across one of these boards. i only recommend using the official nitrocaster board, if youcan find one unused. ymmv with the chinese gear. better just use an unmodded x230 or get a different machine.

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>
2024-01-25coreboot/default: update coreboot to January 2024Leah Rowe
Base revision changed to: commit b6cbfa977f63d57d5d6b9e9f7c1cef30162f575a Author: Morris Hsu <morris-hsu@quanta.corp-partner.google.com> Date: Fri Jan 5 16:48:17 2024 +0800 mb/google/dedede/var/metaknight:Add fw_config probe for multi codec and amplifier Of note: Several out-of-tree ports have been adjusted to use the new SPD config style, where it is defined in devicetree. I manually updated the E6530 patch myself, based on the update that Nicholas did on E6430 (Nicholas will later update the E6530 patch himself, and I'll re-merge the patch). Several upstream patches now exist in this revision, that we were able to remove from lbmk. The heap size patch was reverted upstream, as we did, but see: https://review.coreboot.org/c/coreboot/+/80023 https://review.coreboot.org/c/coreboot/+/79525 Although we still disable the TSEG Stage Cache, ivy/sandy/haswell should be reliable on S3 now (leaving TSEG Stage Cache disabled, for now, anyway). Also included in upstream now: commit 29030d0f3dad2ec6b86000dfe2c8e951ae80bf94 Author: Bill Xie <persmule@hardenedlinux.org> Date: Sat Oct 7 01:32:51 2023 +0800 drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume Further patches from upstream: commit 432e92688eca0e85cbaebca3232f65936b305a98 Author: Bill Xie <persmule@hardenedlinux.org> Date: Fri Nov 3 12:34:01 2023 +0800 drivers/pc80/rtc/option.c: Reset only CMOS range covered by checksum This should fix S3 on GM45 thinkpads.

2023-12-27update/trees: further simplify crossgcc handlingLeah Rowe
arch no longer needs to be set, on multi-tree projects, and it has been renamed to xarch the new behaviour is: if xarch is set, treat it as a list of crossgcc targets and go through the list. set the first one as the target, for what lbmk builds, but build all of the defined crossgccc targets crossgcc_ada is now xlang, and defines which languages to build, rather than whether to build gcc-gnat Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-23don't delete microcode updates in rom imagesLeah Rowe
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.

2023-12-21build/roms: remove modify_coreboot_rom()Leah Rowe
don't handle "romtype" at all, in board target.cfg files add /dev/null as pike2008 rom on amd boards. this serves the same purpose, adding them as empty vga roms, to add an empty rom in cbfs. pike2008 cards cause seabios to hang, when their oproms are executed, so we insert a fake rom on i945 thinkpads, use the coreboot config option: CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK when set, this enables the same bootblock copy, for use with bucts. these two cases, namely pike2008 roms and i945 bootblock copies, no longer need to be handled in code Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-12-21update/trees: simplified crossgcc handlingLeah Rowe
only call crossgcc for coreboot and u-boot, but use hostcc for everything else. simplify the checking of which architecture to compile for. "arch" in target.cfg files has been modified, to allow further simplification. without this patch, the logic currently only *barely* avoids using crossgcc on things like utils, and only works in practise because, in practise, lbmk only works on x86_64 anyway. the new logic, as per this patch, is simpler and more robust.

2023-11-05coreboot: re-configure gm45 thinkpads from scratchLeah Rowe
TSEG Stage Cache enabled again, because disabling it did not affect S3 in any way. Many configs have changed, and debug level is set to 7. In testing with V-T60 on IRC, it wasn't just removal of the DDR2 patch that I did, but I re-did the configs too, in exactly the same way I've done them here, when testing on an X200 to fix boot issues. Libreboot does not use defconfigs, instead it uses full configs, and these have to be updated. I normally just run make-oldconfig on every config, for revision updates. However, every now and then, we need to re-do them. Play it safe and re-do every config. I've double- and triple-checked that the configs are correct. Signed-off-by: Leah Rowe <leah@libreboot.org>

My previous fix to revert didn't fix S3 on GM45, one of the platforms reported fixed by 78263; I'm merging that instead, at patch set 10. It is referenced by 78815/1 which was split from it, so merge that too (restores overrides of higher values, on certain platforms that we don't use yet). https://review.coreboot.org/c/coreboot/+/78623/10 https://review.coreboot.org/c/coreboot/+/78815/1 Accordingly, update configs to match the new default.

2023-10-29revert coreboot heap size patchLeah Rowe
the patch: https://review.coreboot.org/c/coreboot/+/78270 this has been reverted, because it caused s3 resume issues on most intel laptops in libreboot. i was going to merge this instead: https://review.coreboot.org/c/coreboot/+/78623 however, it's under review, and this doesn't change to the old behaviour; it keeps the new universal config, but changes the default we know the old logic works, so keep that for now. in fact, the offending patch was only merged to main in coreboot, one day before i recently updated coreboot revs in coreboot/default - i used a 12 october revision, the patch above is 11 october i then ran "./update trees -u coreboot" which updated the heap sizes back to the old defaults. this should fix s3 suspend/resume where it was broken, in the libreboot 20231021 release - a point release with this and a few other fixes is planned soon.
