Testing needed. I’ve already tested this update on a few boards myself, but the more the merrier! I’m planning a new Libreboot release some time in the next eight weeks or so; could be sooner, or could be a bit later. ETA somewhere between late August to late September (perhaps early October) of this year; the most recent stable release of Libreboot came out on 25 June 2023.

For all mainboards that provide GRUB or SeaBIOS revisions, new versions of these payloads are now used in Libreboot, as implemented by these patches:

• GRUB is now on version 2.12-rc1 from 10 July 2023, where previously it was on a revision from 14 February 2023. Patch: https://browse.libreboot.org/lbmk.git/commit/?id=27ee975e8676fa14d536219fb827cd64dfb5dc74
• SeaBIOS is now on a revision from 30 May 2023, where previously it was on a 20 January 2023 revision. Patch: https://browse.libreboot.org/lbmk.git/commit/?id=cb8bf380e9e4ab065f597b9ea643897caa4b6ccb

The default cbtree is now based upon coreboot from 2 August 2023, where previously it was based upon coreboot from 17 February 2023. Patch: https://browse.libreboot.org/lbmk.git/commit/?id=705149a3e089fb99e671a47b0acd3a30378dd659

Of note: the HP 8300 USDT port is merged upstream, and included in this revision, so Libreboot’s patch for it is no longer needed, and has been removed (Libreboot previously supported this board out of tree, but now it uses the upstream code).

This update affects the following build targets, in Libreboot’s lbmk which is the automated build system used to produce releases:

d510mo_16mb, d510mo, e6400_4mb, g43t-am3_16mb, g43t-am3, ga-g41m-es2l, hp2560p_8mb, hp2570p_16mb, hp8200sff_4mb, hp8200sff_8mb, hp8300usdt_16mb, hp9470m_16mb, macbook11_16mb, macbook11, macbook21_16mb, macbook21, qemu_arm64_12mb, qemu_x86_12mb, r400_16mb, r400_4mb, r400_8mb, r500_4mb, t400_16mb, t400_4mb, t400_8mb, t420_8mb, t420s_8mb, t430_12mb, t440pmrc_12mb, t500_16mb, t500_4mb, t500_8mb, t520_8mb, t530_12mb, t60_16mb_intelgpu, t60_intelgpu, w500_16mb, w500_4mb, w500_8mb, w530_12mb, w541mrc_12mb, x200_16mb, x200_4mb, x200_8mb, x220_8mb, x230_12mb, x230_16mb, x230edp_12mb, x230t_12mb, x230t_16mb, x301_16mb, x301_4mb, x301_8mb, x60_16mb and x60.

This only affects the default coreboot tree used in Libreboot; the haswell tree (libre MRC on T440p/W541), cros (gru chromebooks) and fam15h trees used on KGPE-D16/KCMA-D8/KFSN4-DRE have not yet been updated.

I want to get as much testing done now as possible, ready for the next release, which will still be marked as a testing release anyway; the next stable release is a long way off, as much new work is planned for Libreboot.

If you wish to provide such testing, please read the following page:

If you can get coreboot logs, those will be useful. Email them to me or submit them attached in issue reports on the bug tracker; if you have any issues, we need to know. Coreboot tends to audit very carefully and updates are usually smooth, but testing is one of Libreboot’s main purposes, to provide stable releases based on coreboot.
