Hello everyone,

I am reaching out to announce that we are once again planning to gather to discuss testing and dependability related topics at the Kernel Testing & Dependability Micro-conference (a.k.a. Testing MC) at Linux Plumbers Conference Japan 2025.

- https://lpc.events/event/19/sessions/228/

The Linux Plumbers 2025 Kernel Testing & Dependability track focuses on advancing the current state of testing of the Linux Kernel and its related infrastructure. The main purpose is to improve software quality and dependability for applications that require predictability and trust.

We aim to create connections between folks working on similar projects, and help individual projects make progress.

This track is intended to promote collaboration between all the communities and people interested in the Kernel testing & dependability. This will help move the conversation forward from where we left off at the LPC 2024 Kernel Testing & Dependability MC. We ask that any topic discussions focus on issues/problems they are facing and possible alternatives to resolving them. The Micro-conference is open to all topics related to testing on Linux, not necessarily in the kernel space.

Suggested topics: - KernelCI: Maestro, kci-dev, kci-deploy, kci-gitlab, new dashboard, KCIDB-ng - Improve sanitizers: KFENCE, KCSAN, KASAN, UBSAN - Using Clang for better testing coverage: Now that the kernel fully supports building with Clang, how can all that work be leveraged into using Clang's features? - Consolidating toolchains: reference collection for increased reproducibility and quality control. - How to spread KUnit throughout the kernel? - Building and testing in-kernel Rust code. - Identify missing features that will provide assurance in safety critical systems. - Which test coverage infrastructures are most effective to provide evidence for kernel quality assurance? How should it be measured? - Explore ways to improve testing framework and tests in the kernel with a specific goal to increase traceability and code coverage. - Regression Testing for safety: Prioritize configurations and tests critical and important for quality and dependability. - Transitioning to test-driven kernel release cycles for mainline and stable: How to start relying on passing tests before releasing a new tag? - Explore how do SBOMs figure into dependability? - Kernel benchmarking and kernel performance evaluation.

We invite you to submit proposals for discussions. Proposals can be submitted here, by 11:59PM UTC on Wednesday, September 10, 2025: - https://lpc.events/event/19/abstracts/
