2024-01-25dell/e6*30: use generic PS2K/PS2M EISAID stringsLeah Rowe
CONFIG_PS2M_EISAID. this is a a string used for the identifier on the mouse, in ACPI. CONFIG_PS2K_EISAID this is used for the keyboard. IASL comes back with this build error: dsdt.asl 1884: Name(_HID, EISAID("DLLK0534")) Error 6045 - ^ EISAID string must be of the form "UUUXXXX" (3 uppercase, 4 hex digits) (DLLK0534) Change DLLK0534 back to PNP0303 and change DLL0534 back to PNP0F13. These are generic identifiers for PS/2 keyboard and mouse. Any generic driver will work with the onboard mouse/keyboard on these machines. They do not need to be changed. These are the default values anyway. Just leave them explicitly defined to the default values, for now; if these options are not set, coreboot will default to these values. This shouldn't break anything for the users. I've reported this to Nicholas Chin, author of those patches. Libreboot imported the new versions of E6430/E6530 board patches in the coreboot revision update, but the new (technically correct) values broke IASL, so I've decided to use the old values for now.

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).

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.

2023-12-31Bump GRUB to 2.12 releaseLeah Rowe

2023-12-30update/trees: support custom make/autogen argumentLeah Rowe
this is now used in grub, for the FS_PAYLOAD_MODULES option in the make command lbmk should generalise as much logic as possible. in some parts of it, logic is hurrently hardcoded, specific to a given project that lbmk uses, but lbmk is essentially a source-based package manager, like what you might find on a small linux distro, so we need to try to be as generic as possible. lbmk is the "build system of build systems", so it has to work generically with as many of them as possible Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-30update/trees: generic cmake handlingLeah Rowe
it is no longer hardcoded just to be handled for uefiextract. it is now defined as cmakedir in target.cfg, for a single or multi tree project. if multi tree, it is applied to the specific 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, this is only used for uefiextract, which is part of src/uefitool Signed-off-by: Leah Rowe <leah@libreboot.org>

the e6400_4mb target has libgfxinit and (if seabios) vgarom initialisation, but has issues on the nvidia model, even when using nomodeset. with this target, e6400nvidia_4mb, only the vgarom initialisation is used, libgfxinit is disabled. on nvidia models, this one should work a little bit better. specifically: nouveau crashes on this machine, with libreboot installed, but you can use nomodeset. however, when libgfxinit is also enabled, nomodeset no longer works properly. so this target disables all video initialisation in coreboot. only seabios will initialise anything video-related, by executing the vga option rom. 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.

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.
