A bug was found whereby seabios_ images are created twice, This was fixed in
the revision e3b77b132e6b5981c09bc1ce282afaae64058ab3. This bug caused vendor
file insertion to fail on release images, because the vendorhashes file would
list the file twice, but one of the hashes would be wrong.
This is because the build system wrongly created U-Boot-only images first with
that name, because the add_uboot function in rom.sh unconditionally created
images with U-Boot in them; the function also creates ARM64 images, where U-Boot
is the primary payload.
On x86 machines, SeaBIOS should be the main payload, chainloading U-Boot.
The build system would then create the actual seabios_ image, replacing the
other one, on x86 machines.
So, the command to create the first image was removed. However, just before
uploading rev1 images, it was discovered that this would cause no U-Boot
images to be built for ARM64 devices, which lead to Revision 2:
Revision 2 (8 December 2024)
See commit ID b910424b5df8ed7c931a7b8f5cc8e34eacf0ca3e.
Revision 1 was reverted, and replaced with the following logic instead:
In add_uboot, the instruction to create a ROM image was changed so that it
only creates one where U-Boot is the primary payload (which is the case for
ARM64).
The source archive is now 20241206rev2 instead of 20241206, and the same
is true of affected images on x86, where vcfg is set in target.cfg.
Revision 3 (11 December 2024)
See commit ID 3b6b283eabe7a655c861d1543aeae49d27566f53 and the two commits
before that.
This revision disables PCI-E Re-plug (hotplug feature) for the NVMe SSD on Dell OptiPlex 3050 Micro, to prevent the device from being renamed randomly; such renaming will cause a system crash if booting Linux from the NVMe.
In my case, I was running RAID1 (SATA+NVMe) and every few days, the RAID1 got unsynced; I simply re-synced and it was fine, but what if that was a RAID0? It would possibly corrupt the entire array.
This revision should prevent the issue from occuring. Without this patch,
the nvme0n1 device (as an example) might randomly rename to nvme0n2, because
Linux would see it as a new device.
This same fix was made to the ThinkPad T480/T480s to fix the same issue there, which manifested during S3 resume, but that bug never made it into the release because it was fixed before the initial release of Libreboot 20241206.
The ROM images were all re-uploaded, compiled from the rev3 tarball, because it was discovered that the rev2 tarballs had a GRUB built showing the old Libreboot 20241008 version number; the actual code in GRUB matched the code for 20241206, but it was a cached GRUB build from just before updating the version number for release. This is because the rev2 ROM image tarballs were done manually, to avoid a full re-build of every target in lbmk. To avoid all doubt, all ROM images have been re-compiled with the version number corrected, from the rev3 tag.
Revision 4 (17 December 2024)
Rev4 fixed a bug: GRUB was not allowing the background image to be changed,
despite rules in grub.cfg that made one in CBFS load before memdisk. This fix
was implemented by no longer inserting background images into GRUB's memdisk,
instead inserting them into CBFS.
This way, you can remove what's in CBFS and replace it with your own, if that's what you want to do.
To celebrate this fix, the default background logo was also changed. The old one was a white silhouette of the Libreboot logo, whereas the new one is of the same shape but shows a rainbow-coloured gradient instead of all-white. This rainbow logo was also used in U-Boot on the very initial Libreboot 20241206 release, and it's also used for the main website logo at the time of this revision.
Basically, this fix was done as an excuse just to do another revision update, to change the logo! The actual bug was actually quite minor and irrelevant.
Revision 5 and 6 (17 December 2024)
All current ROM/src archives in this release match changes up to rev6.
I decided afterall to keep using the boring all-grey silhouette logo in GRUB. I also made the same decision for U-Boot.
The plain logo is less eye catching and looks less out of place, and it's uncontroversial in every way. This revision still contains the fix allowing GRUB backgrounds to be changed. Rev5 made this change to GRUB and Rev6 made it to U-Boot. All ROM images were re-compiled to rev6, and re-uploaded.
A minor change, to be sure. I need Libreboot to be as trouble-free as possible to everyone, and some countries are culturally hostile to the particular colour gradient used by the old logo (from rev4); even if I preferred that logo, I want those users to have no trouble at all using Libreboot in public. Libreboot's only purpose is to provide free boot firmware.
