coreboot 4.10 release notes
|
||
|
|
===========================
|
||
|
|
|
||
|
|
The 4.10 release covers commit a2faaa9a2 to commit ae317695e3
|
||
|
|
There is a pgp signed 4.10 tag in the git repository, and a branch will
|
||
|
|
be created as needed.
|
||
|
|
|
||
|
|
In nearly 8 months since 4.9 we had 198 authors commit 2538 changes
|
||
|
|
to master. Of these, 85 authors made their first commit to coreboot:
|
||
|
|
Welcome!
|
||
|
|
|
||
|
|
Between the releases the tree grew by about 11000 lines of code plus
|
||
|
|
5000 lines of comments.
|
||
|
|
|
||
|
|
Again, a big Thank You to all contributors who helped shape the coreboot
|
||
|
|
project, community and code with their effort, no matter if through
|
||
|
|
development, review, testing, documentation or by helping people asking
|
||
|
|
questions on our venues like IRC or our mailing list.
|
||
|
|
|
||
|
|
What's New
|
||
|
|
----------
|
||
|
|
|
||
|
|
Most of the changes were to mainboards, and on the chipset side, lots
|
||
|
|
of activity concentrated on x86. However compared to previous releases
|
||
|
|
activity (and therefore interest, probably) increased in vboot and in
|
||
|
|
non-x86 architectures. However it's harder this time to give this release
|
||
|
|
a single topic like the last: This release accumulates some of everything.
|
||
|
|
|
||
|
|
Clean Up
|
||
|
|
--------
|
||
|
|
As usual, there was a lot of cleaning up going on, and there notably,
|
||
|
|
a good chunk of this year's Google Summer of Code project to clean out
|
||
|
|
the issues reported by Coverity Scan is already in.
|
||
|
|
|
||
|
|
The only larger scale change that was registered in the pre-release
|
||
|
|
notes was also about cleaning up the tree:
|
||
|
|
|
||
|
|
### `device_t` is no more
|
||
|
|
coreboot used to have a data type, `device_t` that changed shape depending on
|
||
|
|
whether it is compiled for romstage (with limited memory) or ramstage (with
|
||
|
|
unlimited memory as far as coreboot is concerned). It's an old relic from the
|
||
|
|
time when romstage wasn't operated in Cache-As-RAM mode, but compiled with
|
||
|
|
our romcc compiler.
|
||
|
|
|
||
|
|
That data type is now gone.
|
||
|
|
|
||
|
|
Release Notes maintenance
|
||
|
|
-------------------------
|
||
|
|
Speaking of pre-release notes: After 4.10 we'll start a document for
|
||
|
|
4.11 in the git repository. Feel free to add notable achievements there
|
||
|
|
so we remember to give them a shout out in the next release's notes.
|
||
|
|
|
||
|
|
Known Issues
|
||
|
|
------------
|
||
|
|
Sadly, Google Cyan is broken in this release. It doesn't work with the
|
||
|
|
"C environment" bootblock (as compared to the old romcc type bootblock)
|
||
|
|
which is now the default. Sadly it doesn't help to simply revert that
|
||
|
|
change because doing so breaks other boards.
|
||
|
|
|
||
|
|
If you want to use Google Cyan with the release (or if
|
||
|
|
you're tracking the master branch), please keep an eye on
|
||
|
|
https://review.coreboot.org/c/coreboot/+/34304 where a solution for this
|
||
|
|
issue is sought.
|
||
|
|
|
||
|
|
Deprecations
|
||
|
|
------------
|
||
|
|
As announced in the 4.9 release notes, there are no deprecations after 4.10.
|
||
|
|
While 4.10 is also released late and we target a 4.11 release in October we
|
||
|
|
nonetheless want to announce deprecations this time: These are under
|
||
|
|
discussion since January, people are working on mitigations for about as long
|
||
|
|
and so it should be possible to resolve the outstanding issues by the end of
|
||
|
|
October.
|
||
|
|
|
||
|
|
Specifically, we want to require code to work with the following Kconfig
|
||
|
|
options so we can remove the options and the code they disable:
|
||
|
|
|
||
|
|
* C\_ENVIRONMENT\_BOOTBLOCK
|
||
|
|
* NO\_CAR\_GLOBAL\_MIGRATION
|
||
|
|
* RELOCATABLE\_RAMSTAGE
|
||
|
|
|
||
|
|
These only affect x86. If your platform only works without them, please
|
||
|
|
look into fixing that.
