With our new release +process only slowly getting in shape, I decided to take a random commit +and call it 4.1. + +The release itself happens at an arbitrary point in time, but will serve +as a starting point for other activities that require some kind of +starting point to build on, described below. + +Future releases will happen more frequently, and with more guarantees +about the state of the release, like having a cool down phase where +boards can be tested and so on. I plan to create a release every three +months, so the changes between any two release don't become too +overwhelming. + +With the release of coreboot 4.1, you get an announcement (this email), +a git tag (4.1), and tar archives at http://www.coreboot.org/releases/, +for the coreboot sources and the redistributable blobs. + +Starting with coreboot 4.1, we will maintain a high level changelog and +'flag days' document. The latter will provide a concise list of changes +which went into coreboot that require chipset or mainboard code to +change to keep it working with the latest upstream coreboot. + +For the time being, I will run these efforts, but I'll happily share +documentation duties with somebody else. It is a great opportunity to +keep track of things, learn about the project and its design and various +internals, while contributing to the project without the need to code. + +Please contact me (for example by email or on IRC) if you're interested, +and we'll work out how to collaborate on this. + +The process should enable users of coreboot to follow releases if they +want a more static base to build on, while making it easier to follow +along with new developments by providing upgrade documentation. + +Since moving away from a rolling (non-)release model is new for +coreboot, things may still be a bit rough around the edges, but I'll +provide support for any issues that arise from the release process. + +Patrick diff --git a/Documentation/releases/coreboot-4.2-relnotes.md b/Documentation/releases/coreboot-4.2-relnotes.md new file mode 100644 index 0000000000..4d6c670bdf --- /dev/null +++ b/Documentation/releases/coreboot-4.2-relnotes.md @@ -0,0 +1,182 @@ +Announcing coreboot 4.2 +======================= + +Halloween 2015 release - just as scary as that sounds + +Dear coreboot community, +today marks the release of coreboot 4.2, the second release on our time +based release schedule. Since 4.1 there were 936 commits by 90 authors, +increasing the code base by approximately 17000 lines of code. We saw 35 +new contributors - welcome to coreboot! More than 34 developers were +active as reviewers in that period. Thanks go to all contributors who +helped shape this release. + +As with 4.1, the release tarballs are available at +http://www.coreboot.org/releases/. There's also a 4.2 tag and branch in +the git repository. + +This marks the first release that features a changelog comparing it to +the previous release. There was some limited testing to make sure that +the code is usable, and it boots on some devices. A structured test plan +will only become part of the release procedure of future versions. I'm +grateful to Martin for assembling this release's changelog. + +This is also the first release that will be followed by the removal of +old, unused code.

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.

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.
