2023-04-17gm45: re-add mitigations for no-microcode setupLeah Rowe
libreboot will still include microcode updates by default, but mitigations against broken speedstep and reboot (when microcode updates are excluded) were removed following the merge with osboot this patch restores those mitigations; the patch reverts coreboot to older smrr code (which works fine, it isn't critical to use the new behaviour) and disables peci (pointless feature) i'll probably re-tool this later to apply the changes conditionally to whether ucode is present this is not a change in policy. policy says: include cpu microcode updates by default policy also says: libreboot must be configurable microcode removal via cbfstool remove -n, counts as configuration, and in practise is not possible on gm45 patches in current libreboot; this patch corrects that problem, allowing the machines to work somewhat well (same stability issues as before, like MCE errors resulting in kernel panic on high CPU/memory usage, but i digress) happy... hacking
2023-03-04ICH9M: default to 256MB VRAM, not 352MBLeah Rowe
352MB VRAM causes stability issues, according to some reports users can still set it to the higher level when building, if they wish to

e.g. ./ifdtool --nuke me coreboot.rom this will be used by rom release build scripts, to scrub stuff like intel me from the rom
2022-11-28coreboot: add x230edp_12mb, remove x230fhd_12mbAlexei Sorokin
New x230edp_12mb target uses the https://review.coreboot.org/c/coreboot/+/28950 patchset to add an X230_EDP target to the default coreboot branch. Consequently the "fhd" coreboot branch is no longer needed and has been safely removed.
2022-11-19fix gnat build issue on coreboot repositoriesLeah Rowe
backported from newer coreboot revisions, see patch coreboot/default/patches/0014-coreboot-default-fix-crossgcc-build.patch
2022-11-14pragmatic system distribution guideline compliancepsdgLeah Rowe
osboot is now part of libreboot, and will soon shut down. libreboot now conforms to osboot policy.
2022-03-13specifically call python3, in scriptsLeah Rowe
with this change, it's unlikely we'll hit errors again. previously, some projects used were calling "python" which in context was python3, but on some setups, the user only has python2 and python3 but no symlink for "python" (which if exists, we assumed linked to python3) now it's unambiguous. docs/build/ can probably be updated now, as a result of this change, to remove the advice about that
2021-12-01Fix broken SpeedStep on GM45 laptops such as ThinkPad X200, T400, T500, W500Leah Rowe
Coreboot is enabling PECI on these CPUs which, according to Intel erratum, must only be done after loading microcode updates, otherwise the CPUID feature set becomes corrupted. That's my understanding, and I think this is why SpeedStep is broken. To be specific, it could but but operating systems no longer detect that the feature is supported. In any case, belgin on IRC found the commit in coreboot, after a bisect, enabling PECI. This commit in Libreboot adds a patch, reverting coreboot's PECI patch.
2021-11-22update coreboot and nuke tianocore20211122Leah Rowe
tianocore is a liability for the libreboot project. it's a bloated mess, and unreliable, broken on many boards, and basically impossible to audit. i don't trust tianocore, so i'm removing it.

2021-10-31lenovo/t400: Enable all SATA ports (add persmule's patch)Leah Rowe
See: <https://lists.nongnu.org/archive/html/libreboot/2016-08/msg00063.html> This enables all SATA ports, allowing full T400s compatibility. T400s already works just fine, when flashing a T400 ROM, but not all SATA ports were usable. The specific patch is here: <https://lists.nongnu.org/archive/html/libreboot/2016-08/txtgT_L8DC94R.txt> There was also this patch, which coreboot actually adapted upstream: <https://lists.nongnu.org/archive/html/libreboot/2016-08/txtMXyws85Q_P.txt> Yes, this patch was submitted in 2016. I overlooked it, during all this time.
2021-10-31re-add grub backgrounds and update grub. mitigate missing charactersLeah Rowe
mitigate missing characters in unifont for border/arrow characters. this saves space because now it is no longer necessary to add a custom font the background added has the libreboot logo on it, and it's 10kb in size unlike the old gnulove background that was hundreds of KB

2021-08-23coreboot: revert cpu/intel: Configure IA32_FEATURE_CONTROL for alternative SMRRLeah Rowe
This fixes issue 3: https://notabug.org/libreboot/lbmk/issues/3 In this issue, GM45 laptops such as X200/T400 will hang on reboot (normal boot works, and shutting down works too).
2021-05-18libreboot!Leah Rowe
this is forked from the "libre" branch in osboot, which is itself a libre, deblobbed fork of osboot, a blobbed up fork of libreboot libreboot needed to be purged clean. this is the new libreboot development repository. the old one has been abandoned
