A friend gave me the his x1 carbon gen1 some time ago. The x1 carbon is little bit different from other Thinkpad because it's a combination of a Thinkpad and a Ultrabook.

• It has a Trackpoint (and even Trackpoint buttons).
• It has soldered memory (only Elpida memory is support atm).
• It has Full-HD. (missed that on x2xx).

Looking under the hood. The x1 carbon gen1 look very likely as x230.

We are happy to announce the April 2017 release of coreboot, version 4.6.

The 4.6 release covers commit e74f5eaa to commit db508565

Since the last release in October 2016, the coreboot project had 1708 commits by 121 authors.
The release tarballs and gpg signatures are available in the usual place at https://www.coreboot.org/downloads

There is a pgp signed 4.6 tag in the git repository, and a branch will be created as needed.

Changes: Past, ongoing, and future

CBMEM console development and the Linux Kernel

Our cbmem debug console was updated with some nice features. The cbmem console now persists between reboots and is able to be used on some platforms via late init. Also there is a new Linux kernel driver which removes the need for the old cbmem tool to read from the cbmem area. You can find the patch here https://patchwork.kernel.org/patch/9641997/ and it can be enabled via GOOGLE_MEMCONSOLE_COREBOOT kconfig option in your kernel – Note that this name may change going forward.

Critical bugs in TPM 1.2 support

coreboot currently has issues with the TPM 1.2 LPC driver implementation. This leads to a misbehavior in SeaBIOS where the TPM gets temporarily deactivated. We plan to publish the bugfix release 4.6.1 when we have these issues sorted out.

Native graphics and ram init improvements

The native graphics was reworked a while ago and should finally support Windows. Numerous bug fixes and EDID support is also now available. Finally, the native ram initialization for sandybridge/ivybridge platforms got patched and supports more RAM modules.

New and fresh payloads

SeaBIOS, FiLO, and iPXE were all recently updated to the latest versions. Https downloads are the default for all payloads now. We provide the libpayload project which is used for writing own payloads from scratch. The library is MOSTLY licensed under BSD and recently received new functionality in order to prepare for the upcoming replacement for the old nvramcui payload. This new payload is called cbui and is based on the nuklear graphics library including keyboard and mouse support. The cbui payload is currently expected to be merged into the main coreboot tree before the next release.  The upstream repository is here: https://github.com/siro20/coreboot/tree/cbui/payloads/cbui

UEFI support: A long road to go

coreboot can be used with the Tianocore EDK2 UEFI implementation which is open source and available at Github. Sadly it is not currently integrated into the coreboot build. This has several reasons:

• EDK2 only supports GCC 4.8 profile. coreboot is now running on GCC 6.3.0.
• Incompatibilities with code inside the EDK2 which has not been updated.

We started to make progress with the integration into our sources and the hope is that by the end of the summer, we finally support the EDK2 payload out-of-the-box. See the current patch state at http://review.coreboot.org/#/c/15057/

Fighting blobs and proprietary HW components

coreboot’s ultimate goal would be to replace any closed source firmware stack with free software components. Unfortunately this is not always possible due to signed binaries such as the Intel ME firmware, the AMD PSP and microcode. Recently, a way was discovered to let the Intel ME run in a functional error state and reduce it from 1.5/5MB to 80KB. It’s not perfect but it works from Nehalem up to Skylake based Intel systems. The tool is now integrated into the coreboot build system. The upstream repository is https://github.com/corna/me_cleaner

Another ongoing improvement is the new utility blobtool. It is currently used for generating the flash descriptor and GbE configuration data on older mainboard which are known to be free software. It can easily be extended for different binaries with well-defined specifications.

Did you say Ada?

coreboot now supports Ada, and a lot work was done integrating Ada into our toolchain. At the moment only the support for formal verification is missing and will be soon added. At that point, we can prove the absence of runtime errors in our Ada code. In short, everybody can start developing Ada code for our project.

The existing Ada code which can be used from now on is another native graphics initialization which will replace in the long term the current implementation. The native graphics code supports all Intel platforms up to skylake. We offer support for HDMI, VGA, DVI and DP external interfaces as well and is ready to be integrated into our mainboard implementations.

Toolchain updates

A new coreboot toolchain is out. The major toolchain change was going from GCC version 5.3.0 to 6.3.0. There were also minor version updates to GMP, MPFR, Binutils, GDB, IASL, and Clang.

Deprecation policy for boards

Starting with this release there will be a policy for deprecating unmaintained boards. See the end of this announcement for details.

Code removal after the 4.6 release

The only platform currently scheduled for removal is the bifferos/bifferboard & soc/rdc/r8610. This platform is one of two that still uses romcc to compile romstage and doesn’t have cache-as-ram in romstage – the others were all removed long ago. Additionally, it seems to be impossible to buy, so as far as it can be determined, no testing has been done recently.

Code removal after the 4.7 release

One of the things that the coreboot project has struggled with is how to maintain the older platforms while still moving the rest of the platforms forward. Currently there are numerous platforms in the codebase which have not been well maintained.

Starting with the 4.7 release in October, the coreboot leadership is going to set standards that platforms are expected to meet to remain in the active codebase. These will generally be announced 3 – 6 months in advance to give time to get changes in. The expectation is not necessarily even that all work to meet the goal will be completed, but it is expected that a reasonable effort has started to meet the goal at the time of the release. Regardless of the work that’s been done, platforms which have not met the goal by the following release will be removed.

The next expectation that will need to be met for all platforms is cbmem in romstage. This currently affects numerous platforms, including most, if not all of AMD’s platforms. Work to update many of these platforms has started, but there are others that have not made any progress towards this goal. A list of the platforms that are affected by this will be sent to the mailing list shortly.

Code removal after the 4.8 release

To further clean things up, starting with the 4.8 release, any platform that does not have a successful boot logged in the board_status repo in the previous year (that is, within the previous two releases) will be removed from the maintained coreboot codebase. Chips that do not have any associated boards will also be removed. These platforms will be announced before the release so that there is time for people to test if desired.

This is not meant to be a high bar, but as a measure to clean up the codebase and eliminate boards and chips that are actually no longer being used. The cleanup will happen just after the release, so the removed platforms will still be available in the release branch if desired. If there is still interest, developers can bring back old chips and boards by porting them to the new tree (and bringing them to current standards).

This gives everyone until April 2018 to get any boards that they care about tested before the first removal.

All the code removal information will also be sent to the mailing list along with additional details.

A little while back, there were a few requests to switch from the mailing list format to a web-based forum for our official communication channel.  The coreboot leadership wanted to see what the actual preferences of the coreboot community was, so I posted a poll.  The poll was publicized in IRC and on the mailing list itself, so should have been communicated to the people who would be most directly affected by any change.

Poll results

Here are the overall results from all responses:

We had a total of 60 valid responses, and I think the overall results pretty clearly indicate that the coreboot project should NOT move away from the mailing list.

One suggestion was to split the communication into the mailing list for Developers, and a forum for non-developers. To see what the various groups thought, I made a few more charts:

Developer preferences:

So not unexpectedly, the coreboot developers even more overwhelmingly prefer the mailing list to the general results

Non-developer preferences:

So even within the non-developer group, there was a definite preference for the mailing list format.

Finally, I broke the Non-developer group down into the group that said they were coreboot users, as opposed to those that mainly read the mailing list.

coreboot users (non-developers):

 

That group had the highest percentage of people who preferred the forum, but it was still well under 40%.

Suggestions

We also asked people what we should do to improve the mailing list.  Here’s a summary of the suggestions:

• Show people how to set up their (or a different) email client to make reading the mailing list easier.
• Have people be more polite.
• Add a FAQ showing previously asked question and answers.
• A netiquette should be established like on the Linux kernel mailing list.
• Several suggestions to improve the coreboot mailing list archive at https://www.coreboot.org/pipermail/coreboot/
  • Fix the archive so that long threads aren’t spread into different sections by months.
  • Add a search function to the archive
  • Create monthly archives that can be downloaded (This exists.)
  • Update from Pipermail to a more modern archiver like Hyperkitty – https://pypi.python.org/pypi/HyperKitty

Since it doesn’t look like we’re going to switch to a forum, I’m not going to list the suggestions that people had for that.

Follow-up

Over the upcoming weeks, we’ll look at our options, and discuss our options and plans in the bi-weekly coreboot community meetings.

 

The coreboot project applied to join the Software Freedom Conservancy and has been approved for membership by their board.  There is still some work to be done in hammering out the governance details, but we hope to have everything completed by April.

Joining the SFC as coreboot’s fiscal sponsor will allow us to go forward with fundraising, and that all donations to the coreboot project from the United States will be tax-deductible to the extent permitted by law.  Up to this point, coreboot hasn’t had any official way to accept donations or payments.  This has meant that the project was mainly supported financially by members of the coreboot leadership, which has put some limitations on what we were able to do.

Another of the things that joining the SFC means is that we will be formalizing and fully documenting the coreboot leadership structure.  This is one of the Conservancy’s requirements, and something that they will help the project with.

The Conservancy offers a number of other services to its members. We encourage everyone to take a look at the SFC, and to consider joining as individual supporters.

We are happy to announce the release of coreboot 4.5

The 4.5 release covers commit 80a3df260767 to commit 0bc12abc2b26.

This release is the first since the project switched from doing quarterly releases to doing biannual releases.  The next release will be in April of 2017.

Since the last release in April, the coreboot project has had 1889 commits by 119 authors.

The release tarballs and gpg signatures are available in the usual place at https://www.coreboot.org/downloads

There is a 4.5 tag in the git repository, and a branch will be created as needed.

Hello everyone, in the following post I’m going to recap all that I’ve managed to accomplish during the GSoC of this year.

As a disclaimer: I plan to maintain these patches until they are fit to be mainlined or rejected altogether in case of design flaws.

libpayload: replace cbfs_media api with region_device api

This patchset should be complete, I tested it quite thoroughly by using the API to update the bayou payload (separate patch). I'm still waiting on a review on this one so I suspect there will be some cause for nitpicks.

bayou: Adapt to the coreboot-v4 era

Changed the design of the payload to make it integrate better with the current infrastructure of coreboot. The majority of the changes have been documented in the appropriate wiki entry. The patchset is complete and working.

console/serialice: Add SerialICE

The patchset was started and the initial work was done by Patrick Rudolph.
I picked it up from there, fixed the problems that it had and tried to get it in shape. It currently works as expected, waiting on more review/feedback.

serialice: update QEMU to version 2.5
serialice: adapt serialice to work with QEMU stable-2.5

In its current state this patchset produces a working build, all the functionality seems to be intact and SerialICE produces the same output as with the old implementation. There could be some unforeseen problems with the changes in the QEMU infrastructure and it could use a cleanup.

[WIP] src: replace device_t type with pnp/pci_defn_t

This is one of the latest commits that I've worked on, it's still a work in progress but I plan to remove all the the improper uses of device_t and replace it with the appropriate type. It's probably gonna take a while and I suspect the patch is going to be massive. If anyone has any suggestion on how to handle this transition feel free to tell me.

tint: Fix tint and add Kconfig option

The payload works as intended. Only nit is that maintaining a separate patch to apply to the tint code is tricky/messy.

lib/selfboot: Replace rdev_mmap_full()

The code worked, even though it's been a while since I rebased the change to check for conflicts. Should be an easy fix anyway.

payloads: add support lz4 compression

selfboot: add sequential lz4 payload decompression

The functionality works as expected.

coreinfo: Add support to read timestamps

cbmem: share additional time stamps IDs

Code works as intended, the only thing missing are the commas that should split the timestamps in groups of 3 digits. I couldn't port that part since it relied on a recursive function that no longer worked.

elfwriter: Fix multi-phdrs ELFs parsing

cbfstool: Require "-m ARCH" to extract payloads and stages

cbfstool: Extract payload in ELF

One of the oldest patchset that I wrote, took a while to get it right but it seems to be working wonderfully.

region: Add writeat and eraseat support

Below are a bunch of minor patches that I’ve written to fix the bugs that I’ve encountered while working on the patches above or browsing the source tree:

i945.h: fix #include path

emulation/qemu-i440fx: add cmos.default file

nvramcui: refactor code

pc80/mc146818rtc.h: Replace leftover macro token

lenovo/x60: add GPIOs initialisation before dock check

serialice: update lint filters

payloads: add Kconfig option for bayou

libpayload: split "Drivers" config section in Kconfig

bayou: delete pbuilder utility

filo: Specify libpayload path

cbfstool: Allow to easily build the individual tools

If you have any question regarding these patches you can find me on IRC (avengerf12).

I wanna conclude this post by expressing my gratitude towards the coreboot’s GSoC admins and mentors for the wonderful opportunity that they have given me and to the coreboot community for all the help and suggestions.

Sincerely,

Antonello
