Upcoming release - coreboot 4.11
|
||||
================================
|
||||
|
||||
The 4.11 release is planned for October 2019
|
||||
coreboot 4.11 was released on November 19th.
|
||||
|
||||
Update this document with changes that should be in the release
|
||||
notes.
|
||||
* Please use Markdown.
|
||||
* See the [4.9](coreboot-4.9-relnotes.md) and [4.10](coreboot-4.10-relnotes.md)
|
||||
release notes for the general format.
|
||||
* The chip and board additions and removals will be updated right
|
||||
before the release, so those do not need to be added.
|
||||
This release cycle was a bit shorter to get closer to our regular
|
||||
schedule of releasing in spring and autumn.
|
||||
|
||||
Since 4.10 there were 1630 new commits by over 130 developers.
|
||||
Of these, about 30 contributed to coreboot for the first time.
|
||||
|
||||
Thank you to all contributors who made 4.11 what it is and welcome
|
||||
to the project to all new contributors!
|
||||
|
||||
Clean Up
|
||||
--------
|
||||
|
||||
The past few months saw lots of cleanup across the source tree:
|
||||
|
||||
The included headers in source files were stripped down to avoid reading
|
||||
unused headers, and unused code fragments, duplicate preprocessor symbols
|
||||
and configuration options were eliminated. Even ACPI got its share
|
||||
of attention, making our tables and bytecode more standards compliant
|
||||
than ever.
|
||||
|
||||
The code across Intel's chipsets was unified some more into drivers for
|
||||
common function blocks, an effort we're more confident will succeed now
|
||||
that Intel itself is driving it.
|
||||
|
||||
Chipset work
|
||||
------------
|
||||
|
||||
Most activity in the last couple months was on Intel support,
|
||||
specifically the Kaby Lake and Cannon Lake drivers were extended
|
||||
for the generations following them.
|
||||
|
||||
On ARM, the Mediatek 8173 chipset support saw significant work while
|
||||
the AMD side worked on getting Picasso support in.
|
||||
|
||||
But everything else also saw some action, the relatively old
|
||||
(e.g. Intel GM45, Via VX900), the tiny (RISC-V) and the obscure
|
||||
(Quark).
|
||||
|
||||
Verified Boot
|
||||
-------------
|
||||
|
||||
The vboot feature that Chromebooks brought into coreboot was extended
|
||||
to work on devices that weren't specially adapted for it: In addition
|
||||
to its original device family it's now supported on various Lenovo
|
||||
laptops, Open Compute Project systems and Siemens industrial machines.
|
||||
|
||||
Eltan's support for measured boot continues to be integrated with
|
||||
vboot, sharing data structures and generally working together where
|
||||
possible.
|
||||
|
||||
New devices
|
||||
-----------
|
||||
|
||||
With 4.11 there's the beginning of support for Intel Tiger Lake and
|
||||
Qualcomm's SC7180 SoCs, while we removed the unmaintained support
|
||||
for Allwinner's A10 SoC.
|
||||
|
||||
There are also 25 new mainboards in our tree:
|
||||
|
||||
* AMD PADMELON
|
||||
* ASUS P5QL-EM
|
||||
* EMULATION QEMU-AARCH64

* RAZER BLADE-STEALTH KBL

||||
* SIEMENS MC-APL6
|
||||
* SUPERMICRO X11SSH-TF
|
||||
* SUPERMICRO X11SSM-F
|
||||
|
||||
In addition to the Cubieboard (which uses the A10 SoC), we also
|
||||
removed Google Hatch WHL.

Deprecations
|

------------
|

|
