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. It provides an automated build system for the configuration and
|
|
installation of coreboot ROM images, making coreboot easier to use for
|
|
non-technical people. 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:
|
|
-----------------------------
|
|
|
|
* **Dell Latitude E6400 (laptop)** (GM45, blob-free, flashable entirely in
|
|
software, no disassembly required!) - courtesy Nicholas Chin, `nic3-14159` on
|
|
Libreboot IRC.
|
|
* HP Compaq 8200 Elite SFF (desktop), courtesy Riku Viitanen (`Riku_V` on
|
|
Libreboot IRC) - *Sandybridge* hardware generation, really nice machine,
|
|
cheap, easy to flash, supports 32GB RAM, multiple HDDs etc.
|
|
* HP EliteBook Folio 9470m (laptop), courtesy Riku Viitanen (IvyBridge gen)
|
|
* HP EliteBook 2560p (laptop), courtesy Riku Viitanen (*seriously* cool guy) -
|
|
Sandybridge hardware gen
|
|
|
|
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. Patch courtesy
|
|
Leah Rowe.
|
|
* GRUB patch: fix hanging on HP EliteBooks, by implementing a 200ms timeout
|
|
for PS/2 keyboard initialisation. Patch courtesy of Riku Viitanen, and it
|
|
fixes this issue which has existed in coreboot *for years*:
|
|
<https://browse.libreboot.org/lbmk.git/plain/resources/grub/patches/0005-at-keyboard-timeout.patch?id=20192c08488104f5cacc1f3842ae8e0ee74c44ef>
|
|
* `build/release/roms`: HP KBC1126 EC firmware scrubbed from release ROMs, for
|
|
re-insertion later via `./update blobs download` and `./update blobs inject` like
|
|
with ME images via `me_cleaner` - for HP laptops. Patch courtesy Leah Rowe.
|
|
* `util/nvmutil`: sorted includes alphabetically; `sys/` first (puffy!) -
|
|
courtesy Leah Rowe.
|
|
* `util/e6400-flash-unlock`: New utility for Dell Latitude E6400 added, written
|
|
by Nicholas Chin (`nic3-14159` on Libreboot IRC). It sends EC commands to
|
|
pull a GPIO connected to `GPIO33`/`HDA_DOCK_EN` in the chipset to a low logic
|
|
state, disabling IFD-based flash protections. Additionally, it bypasses the
|
|
SMM BIOS lock protection by disabling SMIs, and since Dell's own BIOS offers
|
|
no other protections, 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 (courtesy Leah Rowe)
|
|
* `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 `./update blobs 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!)
