Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
Libreboot provides boot firmware for supported x86/ARM machines, starting a
|
||
|
|
bootloader that then loads your operating system. It replaces proprietary
|
||
|
|
BIOS/UEFI firmware on x86 machines, and provides an *improved* configuration
|
||
|
|
on ARM-based chromebooks supported (U-Boot bootloader, instead of Google's
|
||
|
|
depthcharge bootloader). On x86 machines, the GRUB and SeaBIOS coreboot
|
||
|
|
payloads are officially supported, provided in varying configurations per
|
||
|
|
machine. You can find the list of supported hardware in the Libreboot
|
||
|
|
documentation.
|
||
|
|
|
||
|
|
The last Libreboot release, version 20230413, was released on 13 April
|
||
|
|
in 2023. *This* new release, Libreboot 20230423, is released today on
|
||
|
|
April 23rd, 2023.
|
||
|
|
|
||
|
|
This is marked as a *testing* release, though it is *basically stable*.
|
||
|
|
We've been going at it like crazy, on a big spree adding more mainboards from
|
||
|
|
coreboot. Some fixes to the build system were also made, since the last release
|
||
|
|
only *10 days ago*.
|
||
|
|
|
||
|
|
The *priority* for Libreboot is to add as many new boards as possible, from now
|
||
|
|
to the next stable release (ETA Q3 2023), with many testing releases in
|
||
|
|
between. Release early, release often. Rigorious testing ensues.
|
||
|
|
|
||
|
|
Build from source
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
*This* release was build-tested on Debian *Sid*, as of 23 April 2023. Your
|
||
|
|
mileage may vary, with other distros. Refer to Libreboot documentation.
|
||
|
|
|
||
|
|
KCMA-D8 and KGPE-D16 wanted!
|
||
|
|
----------------------------

||
|
|
|
||
|
|
[ASUS KGPE-D16 and KCMA-D8 needed for testing!](kgpe-d16.md)
|
||
|
|
|
||
|
|
These boards still haven't made it back to Libreboot, but I wish to re-add
|
||
|
|
them in a future release. If you can give/loan me a fully assembled workstation
|
||
|
|
with one (or both) of these, I would appreciate it. Please
|
||
|
|
[get in touch](../contact.md)!

|
||
|
|
Work done since last release
|
||
|
|
============================
|
||
|
|
|
||
|
|
This is in the last *10 days*, since the previous release was 10 days ago!
|
||
|
|
Ergo, this is a very conservative changelog. It seems Libreboot has been
|
||
|
|
releasing almost fortnightly, as of late; perhaps this could continue from
|
||
|
|
now on.
|
||
|
|
|
||
|
|
New mainboards now supported:
|
||
|

|

|
|
software, no disassembly required!) - courtesy Nicholas Chin, `nic3-14159` on

|
|
cheap, easy to flash, supports 32GB RAM, multiple HDDs etc.

Build system changes:
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
* **GM45 no-microcode bug mitigations re-added: revert to old SMRR handling
|
||
|
|
and disable PECI (for e.g. X200/T400 users who want to [remove microcode
|
||
|
|
updates](gm45microcode.md), using `cbfstool`) - fixes broken reboot/speedstep
|
||
|
|
CPU scaling in such configuration.** - Patch:
|
||
|
|
<https://browse.libreboot.org/lbmk.git/commit/?id=bd4ea9a02845b22a09b73ebb015ce134234d100b>
|
||
|
|
(patch by Leah Rowe) - this also affects Dell Latitude E6400, and it can be
|
||
|
|
used there on that board. We recommend *keeping* microcode updates, but these
|
||
|
|
mitigations were re-added to satisfy users of older releases that excluded
|
||
|
|
them, who want to still have the option to feasibly run without them.
|
||
|
|
[This is ill advised, due to bugs that the microcode updates
|
||
|
|
fix](gm45microcode.md)
|
||
|
|
* `blobutil/inject`: Fixed bad variable expansion pattern
|
||
|
|
* `build/release/roms`: HP KBC1126 EC firmware scrubbed from release ROMs, for
|
||
|
|
re-insertion later via `./blobutil download` and `./blobutil inject` like
|
||
|
|
with ME images via `me_cleaner` - for HP laptops.
|
||
|
|
* `build/dependencies/parabola`: New script for installing build dependencies
|
||
|
|
in Parabola GNU+Linux, courtesy of Riku Viitanen (`Riku_V` on Libreboot IRC)
|
||
|
|
* `util/nvmutil`: sorted includes alphabetically; `sys/` first (puffy!)
|
||
|
|
* `util/e6400-flash-unlock`: New utility for Dell Latitude E6400 added, written
|
||
|
|
by Nicholas Chin (`nic3-14159` on Libreboot IRC). It writes EC commands to
|
||
|
|
unlock the flash, pulling `GPIO33`/`HDA_DOCK_EN` to a low logic state. This
|
||
|
|
disables IFD-based flash protections. On Dell E6400, the EC is hooked up to
|
||
|
|
GPIO33 and Dell's own BIOS offers no other protections, so the machine can
|
||
|
|
be flashed *entirely with software on the host CPU*, from Dell BIOS to
|
||
|
|
Libreboot! See:
|
||
|
|
<https://browse.libreboot.org/lbmk.git/tree/util/e6400-flash-unlock>
|
||
|
|
* GRUB payload: `grub.cfg` menu timeout now 30s, not 5s
|
||
|
|
* `blobutil/download`: support downloading KBC1126-based EC firmware for HP
|
||
|
|
laptops. (patch by Leah Rowe)
|
||
|
|
* `blobutil/download: Support extracting `me.bin` from full archives, when
|
||
|
|
running `./blobutil download` - this is done, using the `-M` option
|
||
|
|
in `me_cleaner` (some vendors put whole ROM images with IFD, GBE, ME and BIOS
|
||
|
|
regions in them, inside their BIOS update archives - we only need to get ME
|
||
|
|
from them, to run through `me_cleaner`) in `me_cleaner`. Ninja'd into lbmk by
|
||
|
|
Leah Rowe.

More boards soon!
|
||
|
|
=================
|
||
|
|
|
||
|
|
I've purchased about ~10 HP mainboards, all of the viable sandybridge,
|
||
|
|
ivybridge and haswell ones from coreboot. I'm going to add them all.
|
||
|
|
|
||
|
|
I also have Dell Optiplex 7020 and 9020; these are on coreboot gerrit and
|
||
|
|
will also be added, in the next Libreboot release (Haswell gen).
|
||
|
|
|
||
|
|
I'm going to re-work a lot of the merged Haswell boards, so that they can
|
||
|
|
also make use of Angel's experimental libre MRC raminit and such, currently
|
||
|
|
available on ThinkPad T440p and W541 as an option in Libreboot (including in
|
||
|
|
this release!)
