Introduction
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
*This* new release, Canoeboot 20231107, released today 7 November 2023, is
|
extreme cleanup / grandiose gesture
make canoeboot a truly GNU FSDG compliant coreboot distro,
by removing all overly positive reference to Libreboot;
what remains is technical in nature, so as to provide
historical context since Canoeboot is a fork of Libreboot.
I've stated before that I wish to take a more neutral tone
toward the FSF, in contrast to the *coldboot war* of 2023
when GNU Boot started.
Canoeboot was heavily linking to Libreboot, even going so far
as to call itself "inferior" and tell the reader to use
Libreboot.
From now on, Canoeboot will be maintained as though I actually
believed in FSF propoganda. I don't, but its users do. Treat
them with respect. My reason for providing Canoeboot is
precisely that I wish for such people to have a high quality
coreboot distro, much unlike the inferior *GNU Boot* project;
inferior because to this day, it's still based on very old
Libreboot, with not much changed (of any real substance)
relative to the Libreboot 20220710 release on which it forked.
In general, I've also found a lot of stragglers from when
Canoeboot started, where paragraphs referred to Libreboot that
should have actually referred to Canoeboot, or paragraphs
with Libreboot-specific information that does not make sense
in the Canoeboot project e.g. references to vendor scripts.
The resulting canoeboot.org will now look no different to any
typical reader than a typical FSF-aligned project.
There is a next stage to this, which will become apparent to
everyone if I have my way.

|
|
|
based on the recent Libreboot 20231106 release.
|
2023-11-07 17:15:07 +00:00
|
|
|
The previous release was [Canoeboot 20231103](canoeboot20231103.md), released
|
|
|
|
|
on 3 November 2023. Today's release has focused
|
|
|
|
|
on minor bug fixes, plus tweaks to the GRUB payload. It imports certain fixes
|
|
|
|
|
from the Libreboot 20231106 release, relative to Libreboot 20231101.
|
|
|
|
|
|
|
|
|
|
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/) 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/).

|
|
Work done since last release
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
This is largely a bugfix release. Most notably, boot issues on GM45 thinkpads
|
|
|
|
|
present in the 20231103 release have been resolved.
|
|
|
|
|
|
|
|
|
|
Dell E6400 on its own tree
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
Canoeboot contains a DDR2 raminit patch for Dell Latitude E6400, that increases
|
|
|
|
|
reliability on coldboot, but it negatively affects other GM45 machines that use
|
|
|
|
|
DDR3 RAM instead.
|
|
|
|
|
|
|
|
|
|
This board is no longer provided by `coreboot/default`. Instead, it is provided
|
|
|
|
|
by `coreboot/dell`, and the offending patch has been moved there, along with
|
|
|
|
|
other required patches.
|
|
|
|
|
|
|
|
|
|
This means that the Dell Latitude E6400 still works, and quite reliably, but
|
|
|
|
|
the patch for it will not impact other boards. In some special circumstances,
|
|
|
|
|
Canoeboot 20231103 randomly crashed or rebooted with certain memory modules,
|
|
|
|
|
when using on GM45 ThinkPads (ROM images for those machines were then deleted
|
|
|
|
|
from those release archives). Today's Canoeboot release solves that problem,
|
|
|
|
|
so these machines can be used reliably once again (and ROM images are provided,
|
|
|
|
|
in this Canoeboot 20231107 release).
|
|
|
|
|
|
|
|
|
|
Coreboot, GRUB, U-Boot and SeaBIOS revisions
|
|
|
|
|
------------------------------------
|
|
|
|
|
|
|
|
|
|
Canoeboot 20231107 and 20231103 are both based on these revisions:
|
|
|
|
|
|
|
|
|
|
* Coreboot (default): commit ID `d862695f5f432b5c78dada5f16c293a4c3f9fce6`, 12 October 2023
|
|
|
|
|
* Coreboot (dell): commit ID `d862695f5f432b5c78dada5f16c293a4c3f9fce6`, 12 October 2023
|
|
|
|
|
(the `dell` tree does not exist in Canoeboot 20231103, only 20231107)
|
|
|
|
|
* 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
|
|
|
|
|
|
|
|
|
|
Several other fixes and tweaks have been made, in addition to this and the
|
|
|
|
|
E6400 patch mentioned above.

|
|
|
|
|
Build system tweaks
|
|
|
|
|
===================
|
|
|
|
|
|
|
|
|
|
These changes were made:
|
|
|
|
|
|
|
|
|
|
* Documentation now included under `docs/`, not `src/docs/`, in releases,
|
|
|
|
|
including this one.
|
|
|
|
|
* nvmutil: Support `make install`, so now nvmutil can be *installed* to the host.
|
|
|
|
|
Patch courtesy of Riku Viitanen.
|
|
|
|
|
* Use the UK Mirror Service (University of Kent) mirror for GCC downloads and
|
|
|
|
|
other GNU toolchain components, when building coreboot. The GNU HTTP server
|
|
|
|
|
returns 302 status, redirecting to mirrors, but this 302 redirect often fails.
|
|
|
|
|
* Dell Latitude E6400: Set VRAM to maximum (256MB), rather than 32MB.
|
|
|
|
|
* GRUB: Don't print an error message about missing modules. We remove a lot of
|
|
|
|
|
modules in GRUB, because we only need a few, but many GRUB configuration files
|
|
|
|
|
provided by distros will just load GRUB modules frivilously, that we don't
|
|
|
|
|
have. In almost all cases, the user can still boot even in such situations.
|
|
|
|
|
* GRUB: Don't print the missing prefix error on screen (normally seen when
|
|
|
|
|
running GRUB in text mode). The prefix is actually being set, and these
|
|
|
|
|
messages are benign. The message just annoys/confuses some people, so it has
|
|
|
|
|
been hidden by modifying GRUB not to display it at all.
|
|
|
|
|
* GM45 and i945 coreboot configurations were re-made from scratch. In testing,
|
|
|
|
|
certain defaults set by upstream were being overridden unnecessarily by cbmk,
|
|
|
|
|
so they were re-made from scratch. When Canoeboot updates the coreboot
|
|
|
|
|
revision, `make oldconfig` is used on each configuration file, which is
|
|
|
|
|
usually OK, but every now and then we re-do them again. (the alternative is
|
|
|
|
|
to use defconfigs, not full configs, but that has other drawbacks)
|
|
|
|
|
* Untitled static site generator *documentation* also included in the release.
|
|
|
|
|
* Untitled static site generator now included in releases, alongside the
|
|
|
|
|
included Canoeboot documentation (website files, and images).

|

|
|
|
|
|
The following additional commits were picked, which are present in Libreboot's
|
|
|
|
|
Git repository *after* the Libreboot 20231106 release upon which
|
|
|
|
|
Canoeboot 20231107 is based:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
c4d90087 add grub mods: diskfilter,hashsum,loadenv,setjmp
|
|
|
|
|
d0d6decb re-add grub modules: f2fs, json, read, scsi, sleep
|
|
|
|
|
86608721 nvmutil: print usage
|
|
|
|
|
f12f5c3a nvmutil: fix makefile
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
This is a very conservative changelog, because this is largely a bugfix release.

Update on 12 November 2023:
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
This file was also overlooked, and is still present in the release tarball:
|
|
|
|
|
|
|
|
|
|
* `src/vendorcode/amd/agesa/f12/Proc/GNB/Nb/Family/LN/F12NbSmuFirmware.h`

|
|
|
|
|
|
|
This has now been removed, in the Canoeboot git repository (`cbmk.git`), and
|
|
|
|
|
this file will absent, in the next release after Canoeboot 20231107. Thanks go
|
|
|
|
|
to Denis Carikli who reported this. The patch to fix it is here:
|
|
|
