GCC extensions
 | 
			
		||||
--------------
 | 
			
		||||
 | 
			
		||||
GCC is the only officially-supported compiler for coreboot, and a
 | 
			
		||||
variety of its C language extensions are heavily used throughout the
 | 
			
		||||
code base. There have been occasional attempts to add clang as a second
 | 
			
		||||
compiler option, which is generally compatible to the same language
 | 
			
		||||
extensions that have been long-established by GCC.
 | 
			
		||||
 | 
			
		||||
Some GCC extensions (e.g. inline assembly) are basically required for
 | 
			
		||||
proper firmware development. Others enable more safe or flexible
 | 
			
		||||
coding patterns than can be expressed with standard C (e.g. statement
 | 
			
		||||
expressions and `typeof()` to avoid double evaluation in macros like
 | 
			
		||||
`MAX()`). Yet others just add some simple convenience and reduce
 | 
			
		||||
boilerplate (e.g. `void *` arithmetic).
 | 
			
		||||
 | 
			
		||||
Since some GCC extensions are necessary either way, there is no gain
 | 
			
		||||
from avoiding other GCC extensions elsewhere. The use of all official
 | 
			
		||||
GCC extensions is expressly allowed within coreboot. In cases where an
 | 
			
		||||
extension can be replaced by a 100% equivalent C standard feature with
 | 
			
		||||
no extra boilerplate or loss of readability, the C standard feature
 | 
			
		||||
should be preferred (this usually only happens when GCC retains an
 | 
			
		||||
older pre-standardization extension for backwards compatibility, e.g.
 | 
			
		||||
the old pre-C99 syntax for designated initializers). But if there is
 | 
			
		||||
any advantage offered by the GCC extension (e.g. using GCC zero-length
 | 
			
		||||
arrays instead of C99 variable-length arrays because they don't inhibit
 | 
			
		||||
`sizeof()`), there is no reason to deprive ourselves of that, and "this
 | 
			
		||||
is not C standard compliant" should not be a reason to argue against
 | 
			
		||||
its use in reviews.
 | 
			
		||||
 | 
			
		||||
This rule only applies to explicit GCC extensions listed in the
 | 
			
		||||
"Extensions to the C Language Family" section of the GCC manual. Code
 | 
			
		||||
should never rely on incidental GCC translation behavior that is not
 | 
			
		||||
explicitly documented as a feature and could change at any moment.

## Contacts
 | 
			
		||||
 | 
			
		||||
If you are interested in participating in GSoC as a contributor or mentor,
 | 
			
		||||
please have a look at our [community forums] and reach out to us. Working closely
 | 
			
		||||
with the community is highly encouraged, as we've seen that our most successful
 | 
			
		||||
contributors are generally very involved.
 | 
			
		||||
 | 
			
		||||
Felix Singer, David Hendricks and Martin Roth are the coreboot GSoC admins for
 | 
			
		||||
2022. Please feel free to reach out to them directly if you have any questions.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## Why work on coreboot for GSoC?
 | 
			
		||||
 | 
			
		||||
  * coreboot offers you the opportunity to work with various architectures
 | 
			
		||||
    right on the iron. coreboot supports both current and older silicon for a
 | 
			
		||||
    wide variety of chips and technologies.
 | 
			
		||||
 | 
			
		||||
  * coreboot has a worldwide developer and user base.
 | 
			
		||||
 | 
			
		||||
  * We are a very passionate team, so you will interact directly with the
 | 
			
		||||
    project initiators and project leaders.
 | 
			
		||||
 | 
			
		||||
  * We have a large, helpful community. coreboot has some extremely talented
 | 
			
		||||
    and helpful experts in firmware involved in the project. They are ready to
 | 
			
		||||
    assist and mentor contributors participating in GSoC.
 | 
			
		||||
 | 
			
		||||
  * One of the last areas where open source software is not common is firmware.
 | 
			
		||||
    Running proprietary firmware can have severe effects on user's freedom and
 | 
			
		||||
    security. coreboot has a mission to change that by providing a common
 | 
			
		||||
    framework for initial hardware initialization and you can help us succeed.

## Contributor requirements & commitments
 | 
			
		||||
 | 
			
		||||
Google Summer of Code is a significant time commitment for you. Medium-sized
 | 
			
		||||
projects are estimated to take 175 hours, while large-sized projects are
 | 
			
		||||
estimated to take 350 hours. Depending on the project size, this means we
 | 
			
		||||
expect you to work roughly half-time or full-time on your project during the
 | 
			
		||||
three months of coding. We expect to be able to see this level of effort in the
 | 
			
		||||
results.
 | 
			
		||||
 | 
			
		||||
The standard program duration is 12 weeks and in consultation with the mentor
 | 
			
		||||
it can be extended up to 22 weeks. Please keep in mind that the actual number
 | 
			
		||||
of hours you spend on the project highly depends on your skills and previous
 | 
			
		||||
experience.
 | 
			
		||||
 | 
			
		||||
Make sure that your schedule (exams, courses, day job) gives you a sufficient
 | 
			
		||||
amount of spare time. If this is not the case, then you should not apply.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Before applying
 | 
			
		||||
 | 
			
		||||
  * Join the [mailing list] and our other [community forums]. Introduce yourself
 | 
			
		||||
    and mention that you are a prospective GSoC contributor. Ask questions and
 | 
			
		||||
    discuss the project that you are considering. Community involvement is a
 | 
			
		||||
    key component of coreboot development.
 | 
			
		||||
 | 
			
		||||
  * You accept our [Code of Conduct] and [Language style].
 | 
			
		||||
 | 
			
		||||
  * Demonstrate that you can work with the coreboot codebase.
 | 
			
		||||
 | 
			
		||||
    * Look over some of the development processes guidelines: [Getting started],
 | 
			
		||||
      [Tutorial], [Flashing firmware tutorial] and [Coding style].
 | 
			
		||||
 | 
			
		||||
    * Download, build and boot coreboot in QEMU or on real hardware. Please email
 | 
			
		||||
      your serial output results to the [mailing list].
 | 
			
		||||
 | 
			
		||||
    * Look through some patches on Gerrit to get an understanding of the review
 | 
			
		||||
      process and common issues.
 | 
			
		||||
 | 
			
		||||
    * Get signed up for Gerrit and push at least one patch to Gerrit for review.
 | 
			
		||||
      Check the [easy project list][Project ideas] or ask for simple tasks on
 | 
			
		||||
      the [mailing list] or on our other [community forums] if you need ideas.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### During the program
 | 
			
		||||
 | 
			
		||||
  * To pass and to be paid by Google requires that you meet certain milestones.
 | 
			
		||||
 | 
			
		||||
    * First, you must be in good standing with the community before the official
 | 
			
		||||
      start of the program. We expect you to post some design emails to the
 | 
			
		||||
      [mailing list], and get feedback on them, both before applying, and during
 | 
			
		||||
      the "community bonding period" between acceptance and official start.
 | 
			
		||||
 | 
			
		||||
    * You must have made progress and committed significant code before the
 | 
			
		||||
      mid-term point and by the final.
 | 
			
		||||
 | 
			
		||||
    * We require that accepted contributors to maintain a blog, where you are
 | 
			
		||||
      expected to write about your project *WEEKLY*. This is a way to measure
 | 
			
		||||
      progress and for the community at large to be able to help you. GSoC is
 | 
			
		||||
      *NOT* a private contract between your mentor and you.
 | 
			
		||||
 | 
			
		||||
  * You must be active in the community on IRC and the [mailing list].
 | 
			
		||||
 | 
			
		||||
  * You are expected to work on development publicly, and to push commits to the
 | 
			
		||||
    project on a regular basis. Depending on the project and what your mentor
 | 
			
		||||
    agrees to, these can be published directly to the project or to a public
 | 
			
		||||
    repository such as Gitlab or Github. If you are not publishing directly to
 | 
			
		||||
    the project codebase, be aware that we do not want large dumps of code that
 | 
			
		||||
    need to be rushed to meet the mid-term and final goals.
 | 
			
		||||
 | 
			
		||||
We don't expect our contributors to be experts in our problem domain, but we
 | 
			
		||||
don't want you to fail because some basic misunderstanding was in your way of
 | 
			
		||||
completing the task.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## Projects
 | 
			
		||||
 | 
			
		||||
There are many development tasks available in coreboot. We prepared some ideas
 | 
			
		||||
for Summer of Code projects. These are projects that we think can be managed in
 | 
			
		||||
the timeline of GSoC, and they cover areas where coreboot is trying to reach
 | 
			
		||||
new users and new use cases.
 | 
			
		||||

Of course your application does not have to be based on any of the ideas listed.
 | 
			
		||||
It is entirely possible that you have a great idea that we just didn't think of

## coreboot Summer of Code Application
 | 
			
		||||
 | 
			
		||||
coreboot welcomes contributors from all backgrounds and levels of experience.
 | 
			
		||||
 | 
			
		||||
Your application should include a complete project proposal. You should
 | 
			
		||||
document that you have the knowledge and the ability to complete your proposed
 | 
			
		||||
project. This may require a little research and understanding of coreboot prior
 | 
			
		||||
to sending your application. The community and coreboot project mentors are your
 | 
			
		||||
best resource in fleshing out your project ideas and helping with a project
 | 
			
		||||
timeline. We recommend that you get feedback and recommendations on your
 | 
			
		||||
proposal before the application deadline.
 | 
			
		||||
 | 
			
		||||
Please complete the standard GSoC application and project proposal. Provide the
 | 
			
		||||
following information as part of your application. Make sure to provide multiple
 | 
			
		||||
ways of communicating in case your equipment (such as a laptop) is lost,
 | 
			
		||||
damaged, or stolen, or in case of a natural disaster that disrupts internet
 | 
			
		||||
service. You risk automatically failing if your mentor cannot contact you and if
 | 
			
		||||
you cannot provide updates according to GSoC deadlines.

## Mentors
 | 
			
		||||
 | 
			
		||||
Each accepted project will have at least one mentor. We will match mentors and
 | 
			
		||||
contributors based on the project and experience level. If possible, we also
 | 
			
		||||
will try to match their time zones.
 | 
			
		||||
 | 
			
		||||
Mentors are expected to stay in frequent contact with the contributor and
 | 
			
		||||
provide guidance such as code reviews, pointers to useful documentation, etc.
 | 
			
		||||
This should generally be a time commitment of several hours per week.
 | 
			
		||||
 | 
			
		||||
Some projects might have more than one mentor, who can serve as a backup. They
 | 
			
		||||
are expected to coordinate with each other and a contributor on a regular basis,
 | 
			
		||||
and keep track of the contributor process. They should be able to take over
 | 
			
		||||
mentoring duty if one of the mentors is unavailable (vacations, sickness,
 | 
			
		||||
emergencies).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Volunteering to be a mentor
 | 
			
		||||
 | 
			
		||||
If you'd like to volunteer to be a mentor, please read the [GSoC Mentor Guide].
 | 
			
		||||
This will give you a better idea of expectations, and where to go for help.
 | 
			
		||||
After that, contact Org Admins (see coreboot contacts section above).
 | 
			
		||||
 | 
			
		||||
The following coreboot developers have volunteered to be GSoC 2022 mentors.
 | 
			
		||||
Please stop by in our community forums and say hi to them and ask them
 | 
			
		||||
questions.

Each GPIO Community has a Pad Configuration Lock register for a GPP allowing locking
 | 
			
		||||
specific register fields in the PAD configuration register.
 | 
			
		||||
 | 
			
		||||
The Pad Config Lock registers reset type is default hardcoded to **Power Good** and
 | 
			
		||||
it's **not** configurable by GPIO PAD DW0.PadRstCfg. Hence, it may appear that for a GPP,
 | 
			
		||||
the Pad Reset Config (DW0 Bit 31) is configured differently from `Power Good`.
 | 
			
		||||
 | 
			
		||||
This would create confusion where the Pad configuration is returned to its `default`
 | 
			
		||||
value but remains `locked`, this would prevent software to reprogram the GPP.
 | 
			
		||||
Additionally, this means software can't rely on GPIOs being reset by PLTRST# or Sx entry.
 | 
			
		||||
 | 
			
		||||
Hence, as per GPIO BIOS Writers Guide (BWG) it's recommended to change the Pad Reset
 | 
			
		||||
Configuration for lock GPP as `Power Good` so that pad configuration and lock bit are
 | 
			
		||||
always in sync and can be reset at the same time.

plenty of RAM.  The builder builds and stores the git repos and output
 | 
			
		||||
in tmpfs along with the ccache save area, so if there isn't enough

memory, the builds will slow down because of smaller ccache areas and

can run into "out of storage space" errors.

# Coverity Scan for open source firmware
 | 
			
		||||
 | 
			
		||||
## What’s Coverity and Coverity Scan?
 | 
			
		||||
 | 
			
		||||
Coverity is a static analysis tool. It hooks into the build process
 | 
			
		||||
and in addition to the compiler creating object files, Coverity collects
 | 
			
		||||
information about the code. That data is then processed in a separate pass
 | 
			
		||||
to identify common programming errors, like out of bounds accesses in C.
 | 
			
		||||
 | 
			
		||||
Coverity Scan is an online service for Open Source projects providing this
 | 
			
		||||
analysis for free. The analysis pass is done on their servers and issues
 | 
			
		||||
can be handled in their [web UI](https://scan.coverity.com/).
 | 
			
		||||
 | 
			
		||||
The Scan service has some quotas based on code size to avoid overloading
 | 
			
		||||
the system, but even at one build per week, that’s usually good enough
 | 
			
		||||
because the identified issues still need to be triaged and fixed or they
 | 
			
		||||
will simply be re-identified next week.
 | 
			
		||||
 | 
			
		||||
### Triage?
 | 
			
		||||
 | 
			
		||||
The Web UI looks a bit like an issue tracker, even if it’s not a very
 | 
			
		||||
good one. It’s possible to mark identified issues as valid or invalid,
 | 
			
		||||
and annotate them with metadata which CLs fix them. The latter isn’t
 | 
			
		||||
strictly necessary because Coverity Scan simply marks issues it can’t
 | 
			
		||||
find anymore as fixed, but at times it helped identify issues that made
 | 
			
		||||
a comeback.
 | 
			
		||||
 | 
			
		||||
### Alternatives
 | 
			
		||||
 | 
			
		||||
There’s also clang’s scan-build, which is fully open-source, and
 | 
			
		||||
finds different issues. As such, it’s less of an alternative and more
 | 
			
		||||
of a complement.
 | 
			
		||||
 | 
			
		||||
There’s a regular run of that for coreboot but not for the other projects
 | 
			
		||||
hosted at coreboot.org.
 | 
			
		||||
 | 
			
		||||
One downside is that it emits a bunch of HTML to report on issues,
 | 
			
		||||
but there’s no interactivity (e.g. marking issues solved), no way
 | 
			
		||||
to merge multiple builds (e.g. multiple board builds of a single tree)
 | 
			
		||||
or a simple way to extract burndown charts and the like from that.
 | 
			
		||||
 | 
			
		||||
#### Looking for a project?
 | 
			
		||||
 | 
			
		||||
On the upside, it can emit the data in a machine readable format, so if
 | 
			
		||||
anybody needs a project, a scan-build web-frontend like Coverity Scan would
 | 
			
		||||
be feasible without having to go through scan-build’s guts, just by parsing
 | 
			
		||||
text files - plus all the stateful and web parts to build on top.
 | 
			
		||||
 | 
			
		||||
## Logging into Coverity Scan
 | 
			
		||||
 | 
			
		||||
Coverity Scan needs an account. It supports its own accounts and GitHub
 | 
			
		||||
OAuth.
 | 
			
		||||
 | 
			
		||||
Access to the dashboards needs approval: Request and you shall receive.
 | 
			
		||||
 | 
			
		||||
## coreboot & friends and Coverity Scan
 | 
			
		||||
 | 
			
		||||
coreboot, flashrom, Chromium EC and other projects of that family have
 | 
			
		||||
been made Coverity aware, that is, their build systems support building
 | 
			
		||||
with a custom compiler configuration passed in “just right” to enable
 | 
			
		||||
Coverity to add its hooks.
 | 
			
		||||
 | 
			
		||||
The public coreboot CI system at
 | 
			
		||||
[https://qa.coreboot.org/](https://qa.coreboot.org/) regularly does
 | 
			
		||||
builds with Coverity and sends them off to Coverity Scan.

Some projects (e.g. Chromium EC) build a different subset of boards on

each run, ensuring that everything is analyzed eventually. The downside
 | 
			
		||||
is that coverity issues pop up and disappear somewhat randomly as they
 | 
			
		||||
are discovered and go unnoticed in a later build.
 |

More projects that are hosted on review.coreboot.org (potentially as a

mirror, like vboot and EC) could be served through that pipeline. Reach

 | 
			
		||||
+-------------------+---------------------+
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The flash is divided into the following regions, as obtained with
 | 
			
		||||
`ifdtool -f rom.layout backup.rom`:
 | 
			
		||||
```
 | 
			
		||||
00000000:00001fff fd
 | 
			
		||||
00100000:001fffff bios
 | 
			
		||||
00006000:000fffff me
 | 
			
		||||
00002000:00005fff gbe
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
In general, flashing is possible internally and from an external header. It
 | 
			
		||||
might be necessary to specify the chip type; `MX25L1605D/MX25L1608D/MX25L1673E`
 | 
			
		||||
is the correct one, not `MX25L1605`.
 | 
			
		||||
 | 
			
		||||
### Internal flashing
 | 
			
		||||
 | 
			
		||||
Internal access to the flash chip is unrestricted. When installing coreboot,
 | 
			
		||||
only the BIOS region should be updated by passing the `--ifd` and `-i bios`
 | 
			
		||||
parameters to flashrom. A full backup is advisable.
 | 
			
		||||
 | 
			
		||||
Here is an example:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
$ sudo flashrom \
 | 
			
		||||
  -p internal \
 | 
			
		||||
  -c "MX25L1605D/MX25L1608D/MX25L1673E" \
 | 
			
		||||
  -r backup.rom
 | 
			
		||||
$ sudo flashrom \
 | 
			
		||||
  -p internal \
 | 
			
		||||
  -c "MX25L1605D/MX25L1608D/MX25L1673E" \
 | 
			
		||||
  --ifd -i bios \

### External flashing
 | 
			
		||||
 | 
			
		||||
The SPI flash chip on this board can be flashed externally through the
 | 
			
		||||
SPI_ROM1 header while the board is off and disconnected from power. There
 | 
			
		||||
seems to be a diode that prevents the external programmer from powering the
 | 
			
		||||
whole board.
 | 
			
		||||
 | 
			
		||||
The signal assignment on the header is identical to the pinout of the flash
 | 
			
		||||
chip. The pinout diagram below is valid when the PCI slots are on the left
 | 
			
		||||
and the CPU is on the right. Note that HOLD# and WP# must be pulled high
 | 
			
		||||
(to VCC) to be able to flash the chip.

 | 
			
		||||
 | 
			
		||||
## Intel Management Engine
 | 
			
		||||
 | 
			
		||||
The Intel Management Engine (ME) can be disabled by setting the ME_DISABLE
 | 
			
		||||
jumper on the board. It pulls GPIO33 on the ICH10 low, causing the "Flash
 | 
			
		||||
Descriptor Security Override Strap" to be set. This disables the ME and also
 | 
			
		||||
disables any read/write restrictions to the flash chip that may be set in the
 | 
			
		||||
Intel Flash Descriptor (IFD) (none on this board). Note that changing this
 | 
			
		||||
jumper only comes into effect when starting the board from a shutdown or
 | 
			
		||||
suspend state, not during normal operation.
 | 
			
		||||
 | 
			
		||||
To completely remove the ME blob from the flash image and to decrease the size
 | 
			
		||||
of the ME region, thus increasing the size of the BIOS region, `me_cleaner` can
 | 
			
		||||
be used with the `-t`, `-r` and `-S` options.
 | 
			
		||||
 | 
			
		||||
## Fan control
 | 
			
		||||
 | 
			
		||||
There are two fan connectors that can be controlled individually. CPU_FAN
 | 
			
		||||
can only control a fan by a PWM signal and SYS_FAN only by voltage. See
 | 
			
		||||
the mainboard's `devicetree.cb` file for how coreboot configures the Super
 | 
			
		||||
I/O to control the fans.
 | 
			
		||||
 | 
			
		||||
## Variants
 | 
			
		||||
 | 
			
		||||
Various similar mainboards exist, like the Acer Q45T-AM. During a discussion
 | 
			
		||||
in #coreboot on IRC, ECS was suspected to be the original designer of this
 | 
			
		||||
series of mainboards. They have similar models such as the ECS G43T-WM.

 | 
			
		||||
 | 
			
		||||
The flash is divided into the following regions, as obtained with
 | 
			
		||||
`ifdtool -f rom.layout backup.rom`:
 | 
			
		||||
```
 | 
			
		||||
00000000:00000fff fd
 | 
			
		||||
00200000:007fffff bios
 | 
			
		||||
00001000:001fffff me
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
### Internal programming
 | 
			
		||||
 | 
			
		||||
The main SPI flash can be accessed using flashrom. By default, only
 | 
			
		||||
the BIOS region of the flash is writable. If you wish to change any
 | 
			
		||||
other region (Management Engine or flash descriptor), then an external
 | 
			
		||||
programmer is required.
 | 
			
		||||
 | 
			
		||||
The following command may be used to flash coreboot:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
$ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The use of `--noverify-all` is required since the Management Engine
 | 
			
		||||
region is not readable even by the host.
 | 
			
		||||
 | 
			
		||||
```eval_rst
 | 
			
		||||
In addition to the information here, please see the
 | 
			
		||||
:doc:`../../tutorial/flashing_firmware/index`.
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
## Hardware monitoring and fan control
 | 
			
		||||
 | 
			
		||||
There are two fan headers for the CPU cooler, CPU_FAN1 and CPU_FAN2. They share
 | 
			
		||||
a single fan tachometer input on the Super I/O while some dedicated logic
 | 
			
		||||
selects which one is allowed to reach it. Two GPIO pins on the Super I/O are
 | 
			
		||||
used to control that logic. The firmware has to set them; coreboot selects
 | 
			
		||||
CPU_FAN1 by default, but the user can change that setting if it was built with
 | 
			
		||||
CONFIG_USE_OPTION_TABLE:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
$ sudo nvramtool -e cpu_fan_header
 | 
			
		||||
[..]
 | 
			
		||||
$ sudo nvramtool -w cpu_fan_header=CPU_FAN2
 | 
			
		||||
$ sudo nvramtool -w cpu_fan_header=None
 | 
			
		||||
$ sudo nvramtool -w cpu_fan_header=Both
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The setting will take effect after a reboot. Selecting and connecting both fan
 | 
			
		||||
headers is possible but the Super I/O will report wrong fan speeds.
 | 
			
		||||
 | 
			
		||||
Currently there is no automatic, OS-independent fan control, but a software
 | 
			
		||||
like `fancontrol` from the lm-sensors package can be used instead.
 | 
			
		||||
 | 
			
		||||
## Serial port header
 | 
			
		||||
 | 
			
		||||
Serial port 1, provided by the Super I/O, is exposed on a pin header. The
 | 
			
		||||
RS-232 signals are assigned to the header so that its pin numbers map directly
 | 
			
		||||
to the pin numbers of a DE-9 connector. If your serial port doesn't seem to
 | 
			
		||||
work, check if your bracket expects a different assignment. Also don't try to
 | 
			
		||||
connect it directly to a device that operates at TTL levels - it would need a
 | 
			
		||||
level converter like a MAX232.
 | 
			
		||||
 | 
			
		||||
Here is a top view of the serial port header found on this board:
 | 
			
		||||
 | 
			
		||||
                 +---+---+
 | 
			
		||||
             N/C |   | 9 | RI  -> pin 9
 | 
			
		||||
                 +---+---+
 | 
			
		||||
    Pin 8 <- CTS | 8 | 7 | RTS -> pin 7
 | 
			
		||||
                 +---+---+
 | 
			
		||||
    Pin 6 <- DSR | 6 | 5 | GND -> pin 5
 | 
			
		||||
                 +---+---+
 | 
			
		||||
    Pin 4 <- DTR | 4 | 3 | TxD -> pin 3
 | 
			
		||||
                 +---+---+
 | 
			
		||||
    Pin 2 <- RxD | 2 | 1 | DCD -> pin 1
 | 
			
		||||
                 +---+---+
 | 
			
		||||
 | 
			
		||||
## eSATA
 | 
			
		||||
 | 
			
		||||
The eSATA port on the rear I/O panel and the internal connector SATA3_A1 share
 | 
			
		||||
the same controller port on the ASM1061. Attaching an eSATA drive causes a
 | 
			
		||||
multiplexer chip to disconnect the internal port from the SATA controller and
 | 
			
		||||
connect the eSATA port instead. This can be seen on GP23 of the Super I/O
 | 
			
		||||
GPIOs: it is '0' when something is connected to the eSATA port and '1'
 | 
			
		||||
otherwise.

# QEMU PPC64 emulator
 | 
			
		||||
This page describes how to build and run coreboot for QEMU/PPC64.
 | 
			
		||||
 | 
			
		||||
## Building coreboot
 | 
			
		||||
```bash
 | 
			
		||||
make defconfig KBUILD_DEFCONFIG=configs/config.emulation_qemu_power9
 | 
			
		||||
make
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
This builds coreboot with no payload.
 | 
			
		||||
 | 
			
		||||
## Payloads
 | 
			
		||||
You can configure ELF or `skiboot` payload via `make menuconfig`. In either case
 | 
			
		||||
you might need to adjust "ROM chip size" and make it large enough to accommodate
 | 
			
		||||
the payload (see how much space it needs in the error you get if it doesn't
 | 
			
		||||
fit).
 | 
			
		||||
 | 
			
		||||
## Running coreboot in QEMU
 | 
			
		||||
```bash
 | 
			
		||||
qemu-system-ppc64 -M powernv,hb-mode=on \
 | 
			
		||||
                  -cpu power9 \
 | 
			
		||||
                  -bios build/coreboot.rom \

- The default CPU in QEMU for AArch64 is a 604. You specify a suitable
 | 
			
		||||
PowerPC CPU via `-cpu power9`.
 | 
			
		||||
- By default Hostboot mode is off and needs to be turned on to run coreboot
 | 
			
		||||
as a firmware rather than like an OS.
 | 
			
		||||
- `-bios` specifies initial program (bootloader should suffice, but whole image
 | 
			
		||||
works fine too).
 | 
			
		||||
- `-drive` specifies image for emulated flash device.
 | 
			
		||||
 | 
			
		||||
## Running with a kernel
 | 
			
		||||
Loading `skiboot` (built automatically by coreboot or otherwise) allows
 | 
			
		||||
specifying kernel and root file system to be run.
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
qemu-system-ppc64 -M powernv,hb-mode=on \
 | 
			
		||||
                  -cpu power9 \

 | 
			
		||||
```
 | 
			
		||||
 |

- Specify path to your kernel via `-kernel`.

		||||
- Specify path to your rootfs via `-initrd`.

To check the version of **fwupd** you have installed, open a terminal window and enter the below command:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
fwupdmgr --version
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
This will show the version number. **1.5.6** or greater will work.
 | 
			
		||||

 | 
			
		||||
On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and elementaryOS 6, fwupd 1.5.6 can be installed from our PPA with the below terminal commands:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
sudo add-apt-repository ppa:starlabs/ppa
 | 
			
		||||
sudo apt update
 | 
			
		||||
sudo apt install fwupd
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
On Manjaro:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
sudo pacman -Sy fwupd-git flashrom-starlabs
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Instructions for other distributions will be added once fwupd 1.5.6 is available. If you are not using one of the distributions listed above, it is possible to install coreboot using a Live USB.
 | 
			
		||||
 | 
			
		||||
**Disable BIOS Lock**
 | 
			
		||||
BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to coreboot. To disable BIOS Lock:
 | 
			
		||||
 | 
			
		||||
1\. Start with your LabTop turned off\. Turn it on whilst holding the **F2** key to access the BIOS settings.
 | 
			
		||||
2\. When the BIOS settings load, use the arrow keys to navigate to the **Advanced** tab\. Here you will see **BIOS Lock**\.
 | 
			
		||||
3\. Press `Enter` to change this setting from **Enabled** to **Disabled**
 | 
			
		||||
 | 
			
		||||

 | 
			
		||||
 | 
			
		||||
4\. Next, press the `F10` key to **Save & Exit** and then `Enter` to confirm.
 | 
			
		||||
 | 
			
		||||
#### **Switching Branch**
 | 
			
		||||
 | 
			
		||||
Switching branch refers to changing from AMI firmware to coreboot, or vice versa.
 | 
			
		||||
 | 
			
		||||
First, check for new firmware files with the below terminal command:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
fwupdmgr refresh --force
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Then, to change branch, enter the below terminal command:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
fwupdmgr switch-branch
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
You can then select which branch you would like to use, by typing in the corresponding number:
 | 
			
		||||

 | 
			
		||||
You will be prompted to confirm, press `y` to continue or `n` to cancel.
 | 
			
		||||
 | 
			
		||||
Once the switch has been completed, you will be prompted to restart.
 | 
			
		||||
 | 
			
		||||
The next reboot can take up to **5 minutes,** do not interrupt this process or disconnect the charger. Once the reboot is complete, that's it - you'll continue to receive updates for whichever branch you are using.
 | 
			
		||||
 | 
			
		||||
You can switch branch at any time.

## Building coreboot
 | 
			
		||||
 | 
			
		||||
### Preliminaries
 | 
			
		||||
 | 
			
		||||
Prior to building coreboot the following files are required:
 | 
			
		||||
* Intel Flash Descriptor file (descriptor.bin)
 | 
			
		||||
* Intel Management Engine firmware (me.bin)
 | 
			
		||||
* ITE Embedded Controller firmware (ec.bin)
 | 
			
		||||
 | 
			
		||||
The files listed below are optional:
 | 
			
		||||
- Splash screen image in Windows 3.1 BMP format (Logo.bmp)
 | 
			
		||||
 | 
			
		||||
These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.
 | 
			
		||||
 | 
			
		||||
### Build
 | 
			
		||||
 | 
			
		||||
The following commands will build a working image:
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
make distclean
 | 
			
		||||
make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_starbook_tgl
 | 
			
		||||
make
 | 
			
		||||
```

# Platforms supported on branches
 | 
			
		||||
 | 
			
		||||
For one reason or another, platforms have been deleted from the master
 | 
			
		||||
branch at times in the past.  Early on, there was no real policy on
 | 
			
		||||
removing boards.  Now the policy is that boards will only be removed if
 | 
			
		||||
they're causing issues in the tree or if they're preventing progress.
 | 
			
		||||
 | 
			
		||||
This does not mean that these boards are gone forever.  The release or
 | 
			
		||||
commit prior to where they were removed can be checked out, and the
 | 
			
		||||
boards can still be built there and updated in a release branch if
 | 
			
		||||
desired.
 | 
			
		||||
 | 
			
		||||
Currently, [jenkins](https://qa.coreboot.org), our continuous
 | 
			
		||||
integration system is configured to build the 4.11, 4.12, 4.14, 4.15,
 | 
			
		||||
and 4.16 branches.  Builders for other branches can be created on
 | 
			
		||||
request.  Likewise, some releases are only marked with tags, and
 | 
			
		||||
branches would need to be created to push new code to.  These branches
 | 
			
		||||
can also be created on request.
 | 
			
		||||
 | 
			
		||||
Patches can be backported from the master branch to any of these other
 | 
			
		||||
branches as needed. The coreboot project will take care of backporting
 | 
			
		||||
critical security fixes, but other patches will need to handled by
 | 
			
		||||
anyone using that release.

coreboot 4.16
 | 
			
		||||
========================================================================
 | 
			
		||||
Upcoming release - coreboot 4.16
 | 
			
		||||
================================
 | 
			
		||||
 | 
			
		||||
The 4.16 release was done on February 25th, 2022.
 | 
			
		||||
The 4.16 release is planned for February, 2022.
 | 
			
		||||
 | 
			
		||||
Since 4.15 there have been more than 1770 new commits by more than 170
 | 
			
		||||
developers.  Of these, more than 35 contributed to coreboot for the
 | 
			
		||||
first time.
 | 
			
		||||
We are increasing the frequency of releases in order to enable others to release quarterly on
 | 
			
		||||
a fresher version of coreboot.
 | 
			
		||||
 | 
			
		||||
Welcome to the project!
 | 
			
		||||
Update this document with changes that should be in the release notes.
 | 
			
		||||
 | 
			
		||||
Thank you to all the developers who continue to make coreboot the
 | 
			
		||||
great open source firmware project that it is.

Plans to move platform support to a branch:
 | 
			
		||||
-------------------------------------------
 | 
			
		||||
After the 4.18 release in November 2022, we plan to move support for any
 | 
			
		||||
boards still requiring RESOURCE_ALLOCATOR_V3 to the 4.18 branch.  V4 was
 | 
			
		||||
introduced more than a year ago and with minor changes most platforms
 | 
			
		||||
were able to work just fine with it. A major difference is that V3 uses
 | 
			
		||||
just one continuous region below 4G to allocate all PCI memory BAR's. V4
 | 
			
		||||
uses all available space below 4G and if asked to, also above 4G too.
 | 
			
		||||
This makes it important that SoC code properly reports all fixed
 | 
			
		||||
resources.
 | 
			
		||||
 | 
			
		||||
Currently only AGESA platforms have issues with it. On Gerrit both
 | 
			
		||||
attempts to fix AMD AGESA codebases to use V4 and compatibility modes
 | 
			
		||||
inside the V4 allocator have been proposed, but both efforts seem
 | 
			
		||||
stalled. See the (not yet merged) documentation
 | 
			
		||||
[CR:43603](https://review.coreboot.org/c/coreboot/+/43603) on it's
 | 
			
		||||
details. It looks like properly reporting all fixed resources is the
 | 
			
		||||
issue.
 | 
			
		||||
 | 
			
		||||
At this point, we are not specifying which platforms this will include
 | 
			
		||||
as there are a number of patches to fix these issues in flight.
 | 
			
		||||
Hopefully, all platforms will end up being migrated to the v4 resource
 | 
			
		||||
allocator so that none of the platforms need to be supported on the
 | 
			
		||||
branch.
 | 
			
		||||
 | 
			
		||||
Additionally, even if the support for the platform is moved to a branch,
 | 
			
		||||
it can be brought back to ToT if they're fixed to support the v4
 | 
			
		||||
allocator.
 | 
			
		||||
 | 
			
		||||
Plans for Code Deprecation
 | 
			
		||||
--------------------------
 | 
			
		||||
As of release 4.18 (November 2022) we plan to deprecate LEGACY_SMP_INIT.
 | 
			
		||||
This also includes the codepath for SMM_ASEG. This code is used to start
 | 
			
		||||
APs and do some feature programming on each AP, but also set up SMM.
 | 
			
		||||
This has largely been superseded by PARALLEL_MP, which should be able to
 | 
			
		||||
cover all use cases of LEGACY_SMP_INIT, with little code changes. The
 | 
			
		||||
reason for deprecation is that having 2 codepaths to do the virtually
 | 
			
		||||
the same increases maintenance burden on the community a lot, while also
 | 
			
		||||
being rather confusing.
 | 
			
		||||
 | 
			
		||||
A few things are lacking in PARALLEL_MP init:
 | 
			
		||||
- Support for !CONFIG_SMP on single core systems. It's likely easy to
 | 
			
		||||
  extend PARALLEL_MP or write some code that just does CPU detection on
 | 
			
		||||
  the BSP CPU.
 | 
			
		||||
- Support SMM in the legacy ASEG (0xa0000 - 0xb0000) region. A POC
 | 
			
		||||
  showed that it's not that hard to do with PARALLEL_MP
 | 
			
		||||
  https://review.coreboot.org/c/coreboot/+/58700
 | 
			
		||||
 | 
			
		||||
No platforms in the tree have any hardware limitations that would block
 | 
			
		||||
migrating to PARALLEL_MP / a simple !CONFIG_SMP codebase.
 | 
			
		||||
* Please use Markdown.
 | 
			
		||||
* See the past few 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.
 | 
			
		||||
 | 
			
		||||
Significant changes
 | 
			
		||||
-------------------
 | 
			
		||||
This is, of course, not a complete list of all changes in the 4.16
 | 
			
		||||
coreboot release, but a sampling of some of the more interesting and
 | 
			
		||||
significant changes.

 | 
			
		||||
Disable the Intel (Converged Security) Management Engine ((CS)ME) via
 | 
			
		||||
HECI based on Intel Core processors from Skylake to Alder Lake. State is
 | 
			
		||||
set based on a CMOS value of `me_state`. A value of `0` will result in a
 | 
			
		||||
(CS)ME state of `0` (working) and value of `1` will result in a (CS)ME
 | 
			
		||||
state of `3` (disabled). For an example CMOS layout and more info, see
 | 
			
		||||
[cse.c](https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/src/soc/intel/common/block/cse/cse.c).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add [AMD] apcb_v3_edit tool
 | 
			
		||||
apcb_v3_edit.py tool edits APCB V3 binaries. Specifically it will inject
 | 
			
		||||
up to 16 SPDs into an existing APCB. The APCB must have a magic number
 | 
			
		||||
at the top of each SPD slot.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Allow enable/disable ME via CMOS
 | 
			
		||||
Add .enable method that will set the CSME state. The state is based on
 | 
			
		||||
the new CMOS option me_state, with values of 0 and 1. The method is very
 | 
			
		||||
stable when switching between different firmware platforms.
 | 
			
		||||
 | 
			
		||||
This method should not be used in combination with USE_ME_CLEANER.
 | 
			
		||||
 | 
			
		||||
State 1 will result in:
 | 
			
		||||
ME: Current Working State   : 4
 | 
			
		||||
ME: Current Operation State : 1
 | 
			
		||||
ME: Current Operation Mode  : 3
 | 
			
		||||
ME: Error Code              : 2
 | 
			
		||||
 | 
			
		||||
State 0 will result in:
 | 
			
		||||
ME: Current Working State   : 5
 | 
			
		||||
ME: Current Operation State : 1
 | 
			
		||||
ME: Current Operation Mode  : 0
 | 
			
		||||
ME: Error Code              : 0
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Move LAPIC configuration to MP init
 | 
			
		||||
Implementation for setup_lapic() did two things -- call enable_lapic()
 | 
			
		||||
and virtual_wire_mode_init().
 | 
			
		||||
 | 
			
		||||
In PARALLEL_MP case enable_lapic() was redundant as it was already
 | 
			
		||||
executed prior to initialize_cpu() call.  For the !PARALLEL_MP case
 | 
			
		||||
enable_lapic() is added to AP CPUs.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add ANSI escape sequences for highlighting
 | 
			
		||||
Add ANSI escape sequences to highlight a log line based on its loglevel
 | 
			
		||||
to the output of "interactive" consoles that are meant to be displayed
 | 
			
		||||
on a terminal (e.g. UART). This should help make errors and warnings
 | 
			
		||||
stand out better among the usual spew of debug messages. For users whose
 | 
			
		||||
terminal or use case doesn't support these sequences for some reason (or
 | 
			
		||||
who simply don't like them), they can be disabled with a Kconfig.
 | 
			
		||||
 | 
			
		||||
While ANSI escape sequences can be used to add color, minicom (the
 | 
			
		||||
presumably most common terminal emulator for UART endpoints?) doesn't
 | 
			
		||||
support color output unless explicitly enabled (via -c command line
 | 
			
		||||
flag), and other terminal emulators may have similar restrictions, so in
 | 
			
		||||
an effort to make this as widely useful by default as possible I have
 | 
			
		||||
chosen not to use color codes and implement this highlighting via
 | 
			
		||||
bolding, underlining and inverting alone (which seem to go through in
 | 
			
		||||
all cases). If desired, support for separate color highlighting could be
 | 
			
		||||
added via Kconfig later.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add cbmem_dump_console
 | 
			
		||||
This function is similar to cbmem_dump_console_to_uart except it uses
 | 
			
		||||
the normally configured consoles. A console_paused flag was added to
 | 
			
		||||
prevent the cbmem console from writing to itself.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add coreboot-configurator
 | 
			
		||||
A simple GUI to change CMOS settings in coreboot's CBFS, via the
 | 
			
		||||
nvramtool utility.  Testing on Debian, Ubuntu and Manjaro with coreboot
 | 
			
		||||
4.14+, but should work with any distribution or coreboot release that
 | 
			
		||||
has an option table. For more info, please check the
 | 
			
		||||
[README](https://web.archive.org/web/20220225194308/https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/util/coreboot-configurator/README.md).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Update live ISO configs to NixOS 21.11
 | 
			
		||||
Update configs so that they work with NixOS 21.11. Drop `iasl` package
 | 
			
		||||
since it was replaced with `acpica-tools`.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Move to U-Boot v2021.10
 | 
			
		||||
Move to building the latest U-Boot.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Support systems with >128 cores
 | 
			
		||||
Each time the spinlock is acquired a byte is decreased and then the
 | 
			
		||||
sign of the byte is checked. If there are more than 128 cores the sign
 | 
			
		||||
check will overflow. An easy fix is to increase the word size of the
 | 
			
		||||
spinlock acquiring and releasing.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add [samsung] sx9360 [proximity sensor] driver
 | 
			
		||||
Add driver for setting up Semtech sx9360 SAR sensor.
 | 
			
		||||
The driver is based on sx9310.c. The core of the driver is the same, but
 | 
			
		||||
the bindings are slightly different.
 | 
			
		||||
 | 
			
		||||
Registers are documented [in the kernel tree:](https://web.archive.org/web/20220225182803/https://patchwork.kernel.org/project/linux-iio/patch/20211213024057.3824985-4-gwendal@chromium.org/)
 | 
			
		||||
Documentation/devicetree/bindings/iio/proximity/semtech,sx9360.yaml
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add driver for Genesys Logic [SD Controller] GL9750
 | 
			
		||||
The device is a PCIe Gen1 to SD 3.0 card reader controller to be
 | 
			
		||||
used in the Chromebook. The datasheet name is GL9750S and the revision
 | 
			
		||||
is 01.
 | 
			
		||||
 | 
			
		||||
The patch disables ASPM L0s.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add support for Realtek RT8125
 | 
			
		||||
The Realtek RT8168 and RT8125 have a similar programming interface,
 | 
			
		||||
therefore add the PCI device ID for the RT8125 into driver for support.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add Fibocom 5G WWAN ACPI support
 | 
			
		||||
Support PXSX._RST and PXSX.MRST._RST for warm and cold reset.
 | 
			
		||||
PXSX._RST is invoked on driver removal.
 | 
			
		||||
 | 
			
		||||
build dependency:
 | 
			
		||||
  soc/intel/common/block/pcie/rtd3
 | 
			
		||||
 | 
			
		||||
This driver will use the rtd3 methods for the same parent in the device
 | 
			
		||||
tree. The rtd3 chip needs to be added on the same root port in the
 | 
			
		||||
devicetree separately.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Fix bug in vr_config
 | 
			
		||||
The `cpu_get_power_max()` function returns the TDP in milliwatts, but
 | 
			
		||||
the vr_config code interprets the value in watts. Divide the value by
 | 
			
		||||
1000 to fix this.
 | 
			
		||||
 | 
			
		||||
This also fixes an integer overflow when `cpu_get_power_max()` returns
 | 
			
		||||
a value greater than 65535 (UINT16_MAX).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Make mixed topology work
 | 
			
		||||
When using a mixed memory topology with DDR4, it's not possible to boot
 | 
			
		||||
when no DIMMs are installed, even though memory-down is available. This
 | 
			
		||||
happens because the DIMM SPD length defaults to 256 when no DIMM SPD is
 | 
			
		||||
available. Relax the length check when no DIMMs are present to overcome
 | 
			
		||||
this problem.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add FSP 2.3 support
 | 
			
		||||
FSP 2.3 specification introduces following changes:
 | 
			
		||||
 | 
			
		||||
1. FSP_INFO_HEADER changes
 | 
			
		||||
   Updated SpecVersion from 0x22 to 0x23
 | 
			
		||||
   Updated HeaderRevision from 5 to 6
 | 
			
		||||
   Added ExtendedImageRevision
 | 
			
		||||
   FSP_INFO_HEADER length changed to 0x50
 | 
			
		||||
 | 
			
		||||
2. Added FSP_NON_VOLATILE_STORAGE_HOB2
 | 
			
		||||
 | 
			
		||||
Following changes are implemented in the patch to support FSP 2.3:
 | 
			
		||||
 | 
			
		||||
- Add Kconfig option
 | 
			
		||||
- Update FSP build binary version info based on ExtendedImageRevision
 | 
			
		||||
  field in header
 | 
			
		||||
- New NV HOB related changes will be pushed as part of another patch
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Join hash calculation for verification and measurement
 | 
			
		||||
This patch moves the CBFS file measurement when CONFIG_TPM_MEASURED_BOOT
 | 
			
		||||
is enabled from the lookup step into the code where a file is actually
 | 
			
		||||
loaded or mapped from flash. This has the advantage that CBFS routines
 | 
			
		||||
which just look up a file to inspect its metadata (e.g. cbfs_get_size())
 | 
			
		||||
do not cause the file to be measured twice. It also removes the existing
 | 
			
		||||
inefficiency that files are loaded twice when measurement is enabled
 | 
			
		||||
(once to measure and then again when they are used). When CBFS
 | 
			
		||||
verification is enabled and uses the same hash algorithm as the TPM, we
 | 
			
		||||
are even able to only hash the file a single time and use the result for
 | 
			
		||||
both purposes.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Skip FSP Notify APIs
 | 
			
		||||
Alder Lake SoC deselects Kconfigs as below:
 | 
			
		||||
- USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
 | 
			
		||||
- USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
 | 
			
		||||
to skip FSP notify APIs (Ready to boot and End of Firmware) and make
 | 
			
		||||
use of native coreboot driver to perform SoC recommended operations
 | 
			
		||||
prior booting to payload/OS.
 | 
			
		||||
 | 
			
		||||
Additionally, created a helper function `heci_finalize()` to keep HECI
 | 
			
		||||
related operations separated for easy guarding again config.
 | 
			
		||||
 | 
			
		||||
TODO: coreboot native implementation to skip FSP notify phase API (post
 | 
			
		||||
pci enumeration) is still WIP.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Add support for PCIe Resizable BARs
 | 
			
		||||
Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can
 | 
			
		||||
indicates support for "Resizable BARs" via a PCIe extended capability.
 | 
			
		||||
 | 
			
		||||
When support this capability is indicated by the device, the size of
 | 
			
		||||
each BAR is determined in a different way than the normal "moving
 | 
			
		||||
bits" method. Instead, a pair of capability and control registers is
 | 
			
		||||
allocated in config space for each BAR, which can be used to both
 | 
			
		||||
indicate the different sizes the device is capable of supporting for
 | 
			
		||||
the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and
 | 
			
		||||
to also inform the device of the size that the allocator actually
 | 
			
		||||
reserved for the MMIO range.
 | 
			
		||||
 | 
			
		||||
This patch adds a Kconfig for a mainboard to select if it knows that it
 | 
			
		||||
will have a device that requires this support during PCI enumeration.
 | 
			
		||||
If so, there is a corresponding Kconfig to indicate the maximum number
 | 
			
		||||
of bits of address space to hand out to devices this way (again, limited
 | 
			
		||||
by what devices can support and each individual system may want to
 | 
			
		||||
support, but just like above, this number can range from 20 to 63) If
 | 
			
		||||
the device can support more bits than this Kconfig, the resource request
 | 
			
		||||
is truncated to the number indicated by this Kconfig.

		||||

coreboot 4.17
 | 
			
		||||
========================================================================
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
The coreboot 4.17 release is being done on June 1, 2022.
 | 
			
		||||
 | 
			
		||||
Since the 4.16 release, we've had over 1260 new commits by around 150

contributors.  Of those people, roughly 15 were first-time contributors.
 | 
			
		||||
 |

As always, we appreciate everyone who has contributed and done the hard
 | 
			
		||||
work to make the coreboot project successful.

These changes are a few that were selected as a sampling of particularly
 | 
			
		||||
interesting commits.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### CBMEM init hooks changed
 | 
			
		||||
 | 
			
		||||
Instead of having per stage x_CBMEM_INIT_HOOK, we now have only 2 hooks:
 | 
			
		||||
* CBMEM_CREATION_HOOK: Used only in the first stage that creates cbmem,
 | 
			
		||||
  typically romstage. For instance code that migrates data from cache
 | 
			
		||||
  as ram to dram would use this hook.
 | 
			
		||||
* CBMEM_READY_HOOK: Used in every stage that has cbmem. An example would
 | 
			
		||||
  be initializing the cbmem console by appending to what previous stages
 | 
			
		||||
  logged.
 | 
			
		||||
The reason for this change is improved flexibility with regards to which
 | 
			
		||||
stage initializes cbmem.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Payloads
 | 
			
		||||
 | 
			
		||||
* SeaBIOS: Update stable release from 1.14.0 to 1.16.0
 | 
			
		||||
* iPXE: Update stable release from 2019.3 to 2022.1
 | 
			
		||||
* Add "GRUB2 atop SeaBIOS" aka "SeaGRUB" option, which builds GRUB2 as a
 | 
			
		||||
  secondary payload for SeaBIOS with GRUB2 set as the default boot
 | 
			
		||||
  entry.  This allows GRUB2 to use BIOS callbacks provided by SeaBIOS as
 | 
			
		||||
  a fallback method to access hardware that the native GRUB2 payload
 | 
			
		||||
  cannot access.
 | 
			
		||||
* Add option to build SeaBIOS and GRUB2 as secondary payloads
 | 
			
		||||
* Add new coreDOOM payload.  See commit message below.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### payloads/external: Add support for coreDOOM payload
 | 
			
		||||
 | 
			
		||||
coreDOOM is a port of DOOM to libpayload, based on the doomgeneric
 | 
			
		||||
source port. It renders the game to the coreboot linear framebuffer,
 | 
			
		||||
and loads WAD files from CBFS.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### cpu/x86/smm_module_load: Rewrite setup_stub
 | 
			
		||||
 | 
			
		||||
This code was hard to read as it did too much and had a lot of state
 | 
			
		||||
to keep track of.
 | 
			
		||||
 | 
			
		||||
It also looks like the staggered entry points were first copied and
 | 
			
		||||
only later the parameters of the first stub were filled in. This
 | 
			
		||||
means that only the BSP stub is actually jumping to the permanent
 | 
			
		||||
smihandler. On the APs the stub would jump to wherever c_handler
 | 
			
		||||
happens to point to, which is likely 0. This effectively means that on
 | 
			
		||||
APs it's likely easy to have arbitrary code execution in SMM which is a
 | 
			
		||||
security problem.
 | 
			
		||||
 | 
			
		||||
Note: This patch fixes CVE-2022-29264 for the 4.17 release.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### cpu/x86/smm_module_loader.c: Rewrite setup
 | 
			
		||||
 | 
			
		||||
This code is much easier to read if one does not have to keep track of
 | 
			
		||||
mutable variables.
 | 
			
		||||
 | 
			
		||||
This also fixes the alignment code on the TSEG smihandler setup code.
 | 
			
		||||
It was aligning the code upwards instead of downwards which would cause
 | 
			
		||||
it to encroach a part of the save state.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### cpu/x86/smm: Add sinkhole mitigation to relocatable smmstub
 | 
			
		||||
 | 
			
		||||
The sinkhole exploit exists in placing the lapic base such that it
 | 
			
		||||
messes with GDT. This can be mitigated by checking the lapic MSR
 | 
			
		||||
against the current program counter.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### cpu/x86/64bit: Generate static page tables from an assembly file
 | 
			
		||||
 | 
			
		||||
This removes the need for a tool to generate simple identity pages.
 | 
			
		||||
Future patches will link this page table directly into the stages on
 | 
			
		||||
some platforms so having an assembly file makes a lot of sense.
 | 
			
		||||
 | 
			
		||||
This also optimizes the size of the page of each 4K page by placing
 | 
			
		||||
the PDPE_table below the PDE.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMI
 | 
			
		||||
 | 
			
		||||
This change will allow the SMI handler to write to the cbmem console
 | 
			
		||||
buffer. Normally SMIs can only be debugged using some kind of serial
 | 
			
		||||
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
 | 
			
		||||
'cbmem -1'. Now that these logs are available to the OS we could also
 | 
			
		||||
verify there were no errors in the SMI handler.
 | 
			
		||||
 | 
			
		||||
Since SMM can write to all of DRAM, we can't trust any pointers
 | 
			
		||||
provided by cbmem after the OS has booted. For this reason we store the
 | 
			
		||||
cbmem console pointer as part of the SMM runtime parameters. The cbmem
 | 
			
		||||
console is implemented as a circular buffer so it will never write
 | 
			
		||||
outside of this area.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### security/tpm/crtm: Add a function to measure the bootblock on SoC level
 | 
			
		||||
 | 
			
		||||
On platforms where the bootblock is not included in CBFS anymore
 | 
			
		||||
because it is part of another firmware section (IFWI or a different
 | 
			
		||||
CBFS), the CRTM measurement fails.
 | 
			
		||||
 | 
			
		||||
This patch adds a new function to provide a way at SoC level to measure
 | 
			
		||||
the bootblock. Following patches will add functionality to retrieve the
 | 
			
		||||
bootblock from the SoC related location and measure it from there.
 | 
			
		||||
In this way the really executed code will be measured.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### soc/amd/common/block/psp: Add platform secure boot support
 | 
			
		||||

### drivers/intel/fsp2_0: Add native implementation for FSP Debug Handler
 | 
			
		||||
 | 
			
		||||
This patch implements coreboot native debug handler to manage the FSP
 | 
			
		||||
event messages.
 | 
			
		||||
 | 
			
		||||
'FSP Event Handlers' feature introduced in FSP to generate event
 | 
			
		||||
messages to aid in the debugging of firmware issues. This eliminates
 | 
			
		||||
the need for FSP to directly write debug messages to the UART and FSP
 | 
			
		||||
might not need to know the board related UART port configuration.
 | 
			
		||||
Instead FSP signals the bootloader to inform it of a new debug message.
 | 
			
		||||
This allows the coreboot to provide board specific methods of reporting
 | 
			
		||||
debug messages, example: legacy UART or LPSS UART etc.
 | 
			
		||||
 | 
			
		||||
This implementation has several advantages as:
 | 
			
		||||
1. FSP relies on XIP 'DebugLib' driver even while printing FSP-S debug
 | 
			
		||||
  messages, hence, without ROM being cached, post 'romstage' would
 | 
			
		||||
  results into sluggish boot with FSP debug enabled.
 | 
			
		||||
  This patch utilities coreboot native debug implementation which is
 | 
			
		||||
  XIP during FSP-M and relocatable to DRAM based resource for FSP-S.
 | 
			
		||||
 | 
			
		||||
2. This patch simplifies the FSP DebugLib implementation and remove the
 | 
			
		||||
   need to have serial port library. Instead coreboot 'printk' can be
 | 
			
		||||
   used for display FSP serial messages. Additionally, unifies the debug
 | 
			
		||||
   library between coreboot and FSP.
 | 
			
		||||
 | 
			
		||||
3. This patch is also useful to get debug prints even with FSP
 | 
			
		||||
   non-serial image (refer to 'Note' below) as FSP PEIMs are now
 | 
			
		||||
   leveraging coreboot debug library instead FSP 'NULL' DebugLib
 | 
			
		||||
   reference for release build.
 | 
			
		||||
 | 
			
		||||
4. Can optimize the FSP binary size by removing the DebugLib dependency
 | 
			
		||||
   from most of FSP PEIMs, for example: on Alder Lake FSP-M debug binary
 | 
			
		||||
   size is reduced by ~100KB+ and FSP-S debug library size is also
 | 
			
		||||
   reduced by ~300KB+ (FSP-S debug and release binary size is exactly
 | 
			
		||||
   same with this code changes). The total savings is ~400KB for each
 | 
			
		||||
   FSP copy, and in case of Chrome AP firmware with 3 copies, the total
 | 
			
		||||
   savings would be 400KB * 3 = ~1.2MB.
 | 
			
		||||
 | 
			
		||||
Note: Need to modify FSP source code to remove 'MDEPKG_NDEBUG' as
 | 
			
		||||
compilation flag for release build and generate FSP binary with non-NULL
 | 
			
		||||
FSP debug wrapper module injected (to allow FSP event handler to execute
 | 
			
		||||
even with FSP non-serial image) in the final FSP.fd.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### security/tpm: Add vendor-specific tis functions to read/write TPM regs
 | 
			
		||||
 | 
			
		||||
In order to abstract bus-specific logic from TPM logic, the prototype
 | 
			
		||||
for two vendor-specific tis functions are added in this
 | 
			
		||||
patch. tis_vendor_read() can be used to read directly from TPM
 | 
			
		||||
registers, and tis_vendor_write() can be used to write directly to TPM
 | 
			
		||||
registers.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### arch/x86: Add support for catching null dereferences through debug regs
 | 
			
		||||
 | 
			
		||||
This commit adds support for catching null dereferences and execution
 | 
			
		||||
through x86's debug registers. This is particularly useful when running
 | 
			
		||||
32-bit coreboot as paging is not enabled to catch these through page
 | 
			
		||||
faults. This commit adds three new configs to support this feature:
 | 
			
		||||
DEBUG_HW_BREAKPOINTS, DEBUG_NULL_DEREF_BREAKPOINTS and
 | 
			
		||||
DEBUG_NULL_DEREF_HALT.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### drivers/i2c/generic: Add support for i2c device detection
 | 
			
		||||
 | 
			
		||||
Add 'detect' flag which can be attached to devices which may or may not
 | 
			
		||||
be present at runtime, and for which coreboot should probe the i2c bus
 | 
			
		||||
to confirm device presence prior to adding an entry for it in the SSDT.
 | 
			
		||||
 | 
			
		||||
This is useful for boards which may utilize touchpads/touchscreens from
 | 
			
		||||
multiple vendors, so that only the device(s) present are added to the
 | 
			
		||||
SSDT. This relieves the burden from the OS to detect/probe if a device
 | 
			
		||||
is actually present and allows the OS to trust the ACPI _STA value.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### util/cbmem: Add FlameGraph-compatible timestamps output
 | 
			
		||||
 | 
			
		||||
Flame graphs are used to visualize hierarchical data, like call stacks.
 | 
			
		||||
Timestamps collected by coreboot can be processed to resemble
 | 
			
		||||
profiler-like output, and thus can be feed to flame graph generation
 | 
			
		||||
tools.
 | 
			
		||||
 | 
			
		||||
Generating flame graph using https://github.com/brendangregg/FlameGraph:
 | 
			
		||||
```
 | 
			
		||||
   cbmem -S > trace.txt
 | 
			
		||||
   FlameGraph/flamegraph.pl --flamechart trace.txt > output.svg
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### src/console/Kconfig: Add option to disable loglevel prefix
 | 
			
		||||
 | 
			
		||||
This patch adds an option to disable loglevel prefixes. This patch helps
 | 
			
		||||
to achieve clear messages when low loglevel is used and very few
 | 
			
		||||
messages are displayed on a terminal. This option also allows to
 | 
			
		||||
maintain compatibility with log readers and continuous integration
 | 
			
		||||
systems that depend on fixed log content.
 | 
			
		||||
 | 
			
		||||
If the code contains:
 | 
			
		||||
  printk(BIOS_DEBUG, "This is a debug message!\n")
 | 
			
		||||
it will show as:
 | 
			
		||||
  [DEBUG]  This is a debug message!
 | 
			
		||||
but if the Kconfig contains:
 | 
			
		||||
  CONFIG_CONSOLE_USE_LOGLEVEL_PREFIX=n
 | 
			
		||||
the same message will show up as
 | 
			
		||||
  This is a debug message!
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### util/cbmem: add an option to append timestamp
 | 
			
		||||
 | 
			
		||||
Add an option to the cbmem utility that can be used to append an entry
 | 
			
		||||
to the cbmem timestamp table from userspace. This is useful for
 | 
			
		||||
bookkeeping of post-coreboot timing information while still being able
 | 
			
		||||
to use cbmem-based tooling for processing the generated data.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
`-a | --add-timestamp ID:          append timestamp with ID\n`
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Additional changes
 | 
			
		||||
------------------
 | 
			
		||||
 | 
			
		||||
The following are changes across a number of patches, or changes worth
 | 
			
		||||
noting, but not needing a full description.
 | 
			
		||||
 | 
			
		||||
* As always, general documentation, code cleanup, and refactoring
 | 
			
		||||
* Remove doxygen config files and targets
 | 
			
		||||
* Get clang compile working for all x86 platforms
 | 
			
		||||
* Work on updating checkpatch to match the current Linux version
 | 
			
		||||
* Timestamps: Rename timestamps to make names more consistent
 | 
			
		||||
* Continue updating ACPI code to ASL 2.0
 | 
			
		||||
* Remove redundant or unnecessary headers from C files
 | 
			
		||||
* arch/x86/acpi_bert_storage.c: Use a common implementation
 | 
			
		||||
* Postcar stage improvements
 | 
			
		||||
* arch/x86/acpi: Consolidate POST code handling
 | 
			
		||||
* intel/common: Enable ROM caching in ramstage
 | 
			
		||||
* vendorcode/amd/agesa: Fix improper use of .data (const is important)
 | 
			
		||||
* sandybridge & gm45: Support setting PCI bars above 4G
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Plans for Code Deprecation
 | 
			
		||||
--------------------------
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### Intel Icelake
 | 
			
		||||
 | 
			
		||||
Intel Icelake is unmaintained. Also, the only user of this platform ever was
 | 
			
		||||
the CRB board. From the looks of it the code never was ready for production as
 | 
			
		||||
only engineering sample CPUIDs are supported.
 | 
			
		||||
 | 
			
		||||
Thus, to reduce the maintanence overhead for the community, it is deprecated
 | 
			
		||||
from this release on and support for the following components will be dropped
 | 
			
		||||
with the release 4.19.
 | 
			
		||||
 | 
			
		||||
  * Intel Icelake SoC
 | 
			
		||||
  * Intel Icelake RVP mainboard
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
### LEGACY_SMP_INIT
 | 
			
		||||
 | 
			
		||||
As of release 4.18 (August 2022) we plan to deprecate LEGACY_SMP_INIT.
 | 
			
		||||
This also includes the codepath for SMM_ASEG. This code is used to start
 | 
			
		||||
APs and do some feature programming on each AP, but also set up SMM.
 | 
			
		||||
This has largely been superseded by PARALLEL_MP, which should be able to
 | 
			
		||||
cover all use cases of LEGACY_SMP_INIT, with little code changes. The
 | 
			
		||||
reason for deprecation is that having 2 codepaths to do the virtually
 | 
			
		||||
the same increases maintenance burden on the community a lot, while also
 | 
			
		||||
being rather confusing.
 | 
			
		||||
 | 
			
		||||
No platforms in the tree have any hardware limitations that would block
 | 
			
		||||
migrating to PARALLEL_MP / a simple !CONFIG_SMP codebase.

### Intel Icelake
 | 
			
		||||
 | 
			
		||||
Intel Icelake code will be removed following the 4.19 release, planned
 |

for November 2022. This consists of the Intel Icelake SOC and Intel
 | 
			
		||||
Icelake RVP mainboard

		||||
 |

 | 
			
		||||
### LEGACY_SMP_INIT
 | 
			
		||||
 | 
			
		||||
Legacy SMP init will be removed from the coreboot master branch
 | 
			
		||||
immediately following this release. Anyone looking for the latest
 | 
			
		||||
version of the code should find it on the 4.18 branch.

# Communication templates related to release management
 | 
			
		||||
 | 
			
		||||
## Deprecation notices
 | 
			
		||||
 | 
			
		||||
Deprecation notices are part of release notes to act as a warning: at some
 | 
			
		||||
point in the future some part of coreboot gets removed. That point must be
 | 
			
		||||
at least 6 months after the release of the notice and it must be right after
 | 
			
		||||
some release: That is, the specified release must still contain the part in
 | 
			
		||||
question while one git commit later it might be removed.
 | 
			
		||||
 | 
			
		||||
The usual reason is progress: Infrastructure module X has been replaced by
 | 
			
		||||
infrastructure module X+1. Removing X helps keep the sources manageable
 | 
			
		||||
and likely opens opportunities to improve the codebase even more.
 | 
			
		||||
Sometimes everything using some module has been converted to its successor
 | 
			
		||||
already and it's natural for such modules to be removed. Even then it might
 | 
			
		||||
be useful to add an entry to the release notes to make everybody aware of
 | 
			
		||||
such a change, for maintainers of incomplete boards that they might keep in
 | 
			
		||||
their local trees and also to give credit to the developers of that change.
 | 
			
		||||
 | 
			
		||||
However this template isn't about such cases. Sometimes the tree contains
 | 
			
		||||
mainboards that rely on X and can't be easily migrated to X+1, often because
 | 
			
		||||
no active developer has access to these mainboards, and that is where this
 | 
			
		||||
type of deprecation notice comes in:
 | 
			
		||||
 | 
			
		||||
A deprecation notice shall outline what is being removed, when it is planned
 | 
			
		||||
for removal (always directly _after_ a future release so it remains clear when
 | 
			
		||||
something is part of coreboot and when it isn't anymore) and which devices
 | 
			
		||||
would be affected at the time of writing. Since past deprecation notices have
 | 
			
		||||
been read as "we plan to remove mainboards A, B, and C", sparking outrage
 | 
			
		||||
with the devoted users of A, B, or C, some care is necessary to make clear
 | 
			
		||||
which parts are slated for removal and which parts are merely consequences
 | 
			
		||||
if no action is taken. Or put differently: It should be obvious that besides
 | 
			
		||||
the deprecation plan, there is a call to action to save a couple of devices
 | 
			
		||||
from becoming officially unsupported.
 | 
			
		||||
 | 
			
		||||
As such, consider the following template when announcing a deprecation:
 | 
			
		||||

### The Thing to remove
 | 
			
		||||
 | 
			
		||||
A short description of the Thing slated for removal.
 | 
			
		||||
 |

A short rationale why it's being removed (e.g. new and better Thing exists
 | 
			
		||||
in parallel; new Thing already demonstrated to work in this many releases;
 | 
			
		||||
removing Thing enables this or that improvement)
 | 
			
		||||
 | 
			
		||||
Timeline: Announced here, Thing will be removed right after the release X
 | 
			
		||||
months out (where X >= 6)
 | 
			
		||||
 | 
			
		||||
#### Call to action
 | 
			
		||||
 | 
			
		||||
Removing Thing requires work on a number of (boards, chipsets, …) that didn't
 | 
			
		||||
make the switch yet. The work approximately looks like this: (e.g. pointers to
 | 
			
		||||
commits where a board has been successfully migrated from Thing to new Thing).
 | 
			
		||||
 | 
			
		||||
Working on migrating away from Thing involves (hardware components, coreboot
 | 
			
		||||
systems, …) 1, 2, and 3. It's difficult to do on the remaining devices because
 | 
			
		||||
...
 | 
			
		||||
 | 
			
		||||
Parts of the tree that need work to become independent of Thing.
 | 
			
		||||
 - chipset A
 | 
			
		||||
   - board A1
 | 
			
		||||
   - board A2
 | 
			
		||||
 - chipset B
 | 
			
		||||
   - board B1
 | 
			
		||||
 | 
			
		||||
We prefer to move them along, but if we don't see any maintenance in our tree
 | 
			
		||||
we'll have to assume that there's no more interest in these platforms. As a
 | 
			
		||||
consequence these devices either have to work without Thing by the removal
 | 
			
		||||
date or they will be removed together with Thing. (side note: these removals
 | 
			
		||||
aren't the law, so if there's work in progress to move boards off X and a
 | 
			
		||||
roadmap that makes it probable to succeed, just not within the announced
 | 
			
		||||
deprecation timeline, we can still decide to postpone the actual removal by
 | 
			
		||||
one release. This needn't be put in the release notes themselves though or
 | 
			
		||||
it might encourage people to look for simple escape hatches.)

		||||
 | 
			
		||||
(If there are developers offering to write patches: )
 | 
			
		||||
There are developers interested in helping move these forward but they can't
 | 
			
		||||
test any changes for lack of equipment. If you have an affected device and
 | 
			
		||||
can run tests on it, please reach out to developers α, β, and γ.

		||||
 | 
			
		||||
(Otherwise maybe something more generic like this: )
