A corresponding [Libreboot 20231101
|

|
|
release](https://libreboot.org/libreboot20231101.html) is also available.
|
||
|
|
Simultaneous same-day release!

|
Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
*This* new release, Canoeboot 20231101, released today 1 November 2023, is
|
||
|
|
based on the [Libreboot 20231101](https://libreboot.org/news/libreboot20231101.html)
|
||
|
|
release, porting changes in it on top of
|
||
|
|
[Canoeboot 20231026](canoeboot20231026.md) as a base. The previous
|
||
|
|
release was Canoeboot 20231026, released on 26 October 2023.
|
||
|
|
|
||
|
|
Canoeboot 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](../docs/install/chromebooks.html) 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](../docs/maintain/) for the
|
||
|
|
[configuration](../docs/build/) and [installation](../docs/install/) of coreboot
|
||
|
|
ROM images, making coreboot easier to use for non-technical people. You can find
|
||
|
|
the [list of supported hardware](../docs/hardware/) in Canoeboot documentation.
|
||
|
|
|
||
|
|
Canoeboot's main benefit is *higher boot speed*,
|
||
|
|
[better](../docs/gnulinux/encryption.md)
|
||
|
|
[security](../docs/gnulinux/grub_hardening.md) and more
|
||
|
|
customisation options compared to most proprietary firmware. As a
|
||
|
|
[libre](https://writefreesoftware.org/learn) software project, the code can be
|
||
|
|
audited, and coreboot does
|
||
|
|
regularly audit code. The other main benefit is [*freedom* to study, adapt and
|
||
|
|
share the code](https://writefreesoftware.org/), a freedom denied by most boot
|
||
|
|
firmware, but not Canoeboot! Booting Linux/BSD is also [well](../docs/gnulinux/)
|
||
|
|
[supported](../docs/bsd/).
|
||
|
|
|
||
|
|
Canoeboot is maintained in parallel with Libreboot, and by the same developer,
|
||
|
|
Leah Rowe, who maintains both projects; Canoeboot implements the [GNU Free
|
||
|
|
System Distribution Guideline](https://www.gnu.org/distros/free-system-distribution-guidelines.en.html)
|
||
|
|
as policy, whereas Libreboot implements its own [Binary Blob Reduction
|
||
|
|
Policy](https://libreboot.org/news/policy.html).
|
||
|
|
|
||
|
|
Work done since last release
|
||
|
|
============================
|
||
|
|
|
||
|
|
This changelog is based on the Libreboot 20231101 changelog; changes from
|
||
|
|
Libreboot 20231101 that are suitable for Canoeboot have been included in
|
||
|
|
this release, and so, this changelog has been modified (based on the
|
||
|
|
Libreboot one):
|
||
|
|
|
||
|
|
Coreboot, GRUB, U-Boot and SeaBIOS revisions
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
Canoeboot 20231026 and 20231101 are both based on these revisions:
|
||
|
|
|
||
|
|
* Coreboot (default): commit ID `d862695f5f432b5c78dada5f16c293a4c3f9fce6`, 12 October 2023
|
||
|
|
* Coreboot (fam15h\_udimm): commit ID `1c13f8d85c7306213cd525308ee8973e5663a3f8`, 16 June 2021
|
||
|
|
* GRUB: commit ID `e58b870ff926415e23fc386af41ff81b2f588763`, 3 October 2023
|
||
|
|
* SeaBIOS: commit ID `1e1da7a963007d03a4e0e9a9e0ff17990bb1608d`, 24 August 2023
|
||
|
|
* U-Boot: commit ID `4459ed60cb1e0562bc5b40405e2b4b9bbf766d57`, 2 October 2023
|
||
|
|
|
||
|
|
However, Canoeboot 20231101 has added several new patches on top of several
|
||
|
|
of these, that fix certain bugs or improve certain functionalities. More
|
||
|
|
information is available elsewhere in this page.

|
Build system tweaks
|
||
|
|
===================
|
||
|
|
|
||
|
|
These changes were made:
|
||
|
|
|
||
|
|
* i945 bootblock copy: during ROM building, the bootblock must be copied from
|
||
|
|
the main 64KB block, to the backup block, for use with `bucts`, but this
|
||
|
|
wasn't done in the last release; this regression has now been fixed.
|
||
|
|
* Re-add SeaGRUB support - enabled on Dell Latitude E6400.
|
||
|
|
* Export `LC_COLLATE` and `LC_ALL`, setting it to `C`, to ensure
|
||
|
|
consistent sorting; the Canoeboot build system heavily relies on sorting
|
||
|
|
by alphanumerical order with numbers and capital letters first, e.g. when
|
||
|
|
applying patches.
|
||
|
|
* GRUB config: Re-wrote the text on some entries to make them easier to
|
||
|
|
understand for novice users.
|
||
|
|
* GRUB: Don't spew the "Unknown key" message on unknown/invalid key presses -
|
||
|
|
otherwise, a faulty keyboard with stuck keys will make the message spew
|
||
|
|
repeatedly, making GRUB unusable.
|
||
|
|
* Revert a heapsize patch in coreboot that broke S3 suspend/resume in some
|
||
|
|
boards - if you do have issues, please send a bug report.
|
||
|
|
* Dell Latitude E6400: fixed keyboard initialisation in GRUB. GRUB
|
||
|
|
was using scancode set 2 without translation. The EC on Dell Latitude E6400
|
||
|
|
allows to set the scancodes and reports back what you set, but only ever
|
||
|
|
actually uses scancode set 1 (XT) - so, the fix makes GRUB always use set 2
|
||
|
|
with translation (treated as 1). This is the same behaviour used in SeaBIOS.
|
||
|
|
This fixes the machine in GRUB, and doesn't break other boards as per testing.
|
||
|
|
* Fix coldboot on Dell Latitude E6400, courtesy of a patch by Angel Pons (IRC
|
||
|
|
inick `hell` on coreboot IRC) - previously, this machine booted unreliably,
|
||
|
|
though reboot was fine. Angel wrote a patch for another board, that also
|
||
|
|
works on the E6400 quite nicely.
|
||
|
|
* QEMU ARM64: video console now enabled in U-Boot (courtesy Alper Nebi Yasak)
|
||
|
|
* Dependencies scripts: updated a few of them, for newer versions of distros.
|
||
|
|
|
||
|
|
This is only about 1 week's worth of changes; this Canoeboot release is
|
||
|
|
largely a bugfix release.
