Investigate non-booting Forlinx OKMX8MX-C board (aarch64) by a_faerber

Description

In the context of a SUSE customer inquiry last year, a Forlinx OKMX8MX-C arm64 board had been relayed to me from China that a customer was not successful booting SUSE Linux Micro on. Typically this happens when the vendor's bootloader (e.g., U-Boot) is not configured properly (e.g., U-Boot's distro boot) to be compliant with Arm SystemReady Devicetree (formerly IR) band. Unfortunately I could not immediately get it to emit any output, to even diagnose why it wasn't working. There was no public documentation on the vendor's website to even confirm I was checking the right UARTs.

Earlier this year (2024) I happened to meet the ODM/OEM, Forlinx, at Embedded World 2024 in Nuremberg and again the Monday before Hackweek 24 at Electronica 2024 in Munich. The big puzzle was that the PCB print "OKMX8MX-C" does not match any current Forlinx product, there being OKMX8MM-C and OKMX8MP-C products with the Mini and Plus variants of NXP i.MX 8M family instead. One suggestion from Forlinx staff was to double-check the DIP switches on the board for boot mode selection.

Goals

Double-check the board name and investigate further what may be wrong with this board.

Resources

none

Progress

• The board name is indeed as spelled above, not matching any product on forlinx.net.
• The DIP switches were set to boot from microSD.
• Changing the DIP switches to eMMC boot did result in UART1 RS-232 output! (although at times garbled with the cable supplied and USB adapter used)
• As feared, it did not automatically load our GRUB from USB.
• Booting our GRUB manually from USB (via eMMC U-Boot commands fatload+bootefi) was unsuccessful, with partially Chinese error messages.
• This confirmed the initial suspicion, already shared with Forlinx at Embedded World 2024, that the Forlinx System-on-Module's boot firmware was not Arm SystemReady Devicetree compliant and that a firmware update would be necessary to remedy that.
• The microSD card turned out not to contain a bootable image but to only include Chinese-language board documentation (dated 20220507) and BSP files. They used a diverging name of OKMX8MQ-C.

Create openSUSE images for Arm/RISC-V boards by avicenzi

Project Description

Create openSUSE images (or test generic EFI images) for Arm and/or RISC-V boards that are not yet supported.

Goal for this Hackweek

Create bootable images of Tumbleweed for SBCs that currently have no images available or are untested.

Consider generic EFI images where possible, as some boards can hold a bootloader.

Document in the openSUSE Wiki how to flash and use the image for a given board.

Boards that I have around and there are no images:

• Rock 3B
• Nano PC T3 Plus
• Lichee RV D1
• StartFive VisionFive (has some image needs testing)

Hack Week 22

• NanoPC T4

Hack Week 21

• NanoPi M4B
• Radxa Zero

Improve various phones kernel mainline support (Qualcomm, Exynos, MediaTek) by pvorel

Similar to previous hackweeks ( https://hackweek.opensuse.org/projects/improve-qualcomm-soc-msm8994-slash-msm8992-kernel-mainline-support, https://hackweek.opensuse.org/projects/test-mainline-kernel-on-an-older-qualcomm-soc-msm89xx-explore-mainline-kernel-qualcomm-mainlining) try to improve kernel mainline support of various phones.

Result

In the end I concentrated again to msm8994:

• 507aae9a3549c ("arm64: dts: qcom: msm8994-angler: Enable power key, volume up/down") (will be in kernel 6.14)
• Testing of c910544d22347 ("arm64: dts: qcom: msm8994: Describe USB interrupts") (will be in kernel 6.14)
• WIP USB support for msm8994

Learn obs/ibs sync tool by xlai

Description

Once images/repo are built from IBS/OBS, there is a tool to sync the image from IBS/OBS to openqa asset directory and trigger openqa jobs accordingly.

Goals

Check how the tool is implemented, and be capable to add/modify our needed images/repo in future by ourselves.

Hack on isotest-ng - a rust port of isotovideo (os-autoinst aka testrunner of openQA) by szarate

Description

Some time ago, I managed to convince ByteOtter to hack something that resembles isotovideo but in Rust, not because I believe that Perl is dead, but more because there are certain limitations in the perl code (how it was written), and its always hard to add new functionalities when they are about implementing a new backend, or fixing bugs (Along with people complaining that Perl is dead, and that they don't like it)

In reality, I wanted to see if this could be done, and ByteOtter proved that it could be, while doing an amazing job at hacking a vnc console, and helping me understand better what RuPerl needs to work.

I plan to keep working on this for the next few years, and while I don't aim for feature completion or replacing isotovideo tih isotest-ng (name in progress), I do plan to be able to use it on a daily basis, using specialized tooling with interfaces, instead of reimplementing everything in the backend

Todo

• Add make targets for testability, e.g "spawn qemu and type"
• Add image search matching algorithm
• Add a Null test distribution provider
• Add a Perl Test Distribution Provider
• Fix unittests https://github.com/os-autoinst/isotest-ng/issues/5
• Research OpenTofu how to add new hypervisors/baremetal to OpenTofu
• Add an interface to openQA cli

Goals

• Implement at least one of the above, prepare proposals for GSoC
• Boot a system via it's BMC

Make more sense of openQA test results using AI by livdywan

Description

AI has the potential to help with something many of us spend a lot of time doing which is making sense of openQA logs when a job fails.

User Story

Allison Average has a puzzled look on their face while staring at log files that seem to make little sense. Is this a known issue, something completely new or maybe related to infrastructure changes?

Goals

• Leverage a chat interface to help Allison
• Create a model from scratch based on data from openQA
• Proof of concept for automated analysis of openQA test results

Bonus

• Use AI to suggest solutions to merge conflicts
  • This would need a merge conflict editor that can suggest solving the conflict
• Use image recognition for needles

Resources

• TensorFlow
• open-webui
• openQA instance of openSUSE
• openQA documentation

Timeline

Day 1

• Conversing with open-webui to teach me how to create a model based on openQA test results
  • Asking for example code using TensorFlow in Python
  • Discussing log files to explore what to analyze
  • Drafting a new project called Testimony (based on Implementing a containerized Python action) - the project name was also suggested by the assistant

Day 2

• Using NotebookLLM (Gemini) to produce conversational versions of blog posts
  • Writing openQA tests in Python
  • Developing in distrobox containers
• Researching the possibility of creating a project logo with AI
  • Asking open-webui, persons with prior experience and conducting a web search for advice

Highlights

• I briefly tested compared models to see if they would make me more productive. Between llama, gemma and mistral there was no amazing difference in the results for my case.
• Convincing the chat interface to produce code specific to my use case required very explicit instructions.
• Asking for advice on how to use open-webui itself better was frustratingly unfruitful both in trivial and more advanced regards.
• Documentation on source materials used by LLM's and tools for this purpose seems virtually non-existent - specifically if a logo can be generated based on particular licenses

Outcomes

• Chat interface-supported development is providing good starting points and open-webui being open source is more flexible than Gemini. Although currently some fancy features such as grounding and generated podcasts are missing.
• Allison still has to be very experienced with openQA to use a chat interface for test review. Publicly available system prompts would make that easier, though.

OpenQA Golang api client by hilchev

Description

I would like to make a simple cli tool to communicate with the OpenQA API

Goals

• OpenQA has a ton of information that is hard to get via the UI. A tool like this would make my life easier :)
• Would potentially make it easier in the future to make UI changes without Perl.
• Improve my Golang skills

Resources

• https://go.dev/doc/
• https://openqa.opensuse.org/api
