kci-dev roadmap 2025/2026

kci-dev is envisioned as a stand-alone KernelCI CLI for both kernel developers and maintainers.


1. Enhanced CI Pipeline Workflow & Automation

Custom pipeline triggers and .kernelci.yml support
  • Let maintainers define custom test plans via a .kernelci.yml file in their tree (similar to GitLab CI).
  • Provide parsing/validation so the file reliably selects the right branches, configs, and platforms.
  • Enable developers to control how KernelCI builds and tests their changes through a clear, versioned plan.
Pre-submit testing and CI integration
  • Gate merges on KernelCI results (e.g., for merge requests and pull requests).
  • Integrate with existing CI systems so critical build/boot failures prevent a merge.
  • Catch regressions before patches land, helping both subsystem maintainers and contributors.
Local KernelCI instance support
  • Support using a local or self-hosted KernelCI instance (including private hardware labs).
  • Make it practical to do “local sanity tests” on key hardware before sending patches upstream.
Deeper git integration
  • Automatically detect repository URL, branch, and HEAD commit from the user’s current git tree.
  • Reduce manual arguments and make repeated testing across many trees simpler.
Scheduled and batch testing
  • Schedule tests (e.g., nightly) and test multiple branches/trees in one action.
  • Produce consolidated reports for maintainers tracking multiple branches (linux-next, stable, subsystem trees).
  • Reduce manual monitoring by summarizing failures and trends over time.

2. Expanded Test Coverage & Reliability Improvements

Broader test suite integration
  • Expand beyond build/boot by exposing additional test suites and signals, such as:
    • KUnit (kernel unit tests)
    • static analysis outputs
    • fuzzing-style workloads
    • driver-specific test suites
    • coverage-related artifacts (where supported)
Targeted configurations and fragments
  • Allow focused test variants using config fragments (e.g., KASAN, lockdep, debug-heavy configs).
  • Support selecting smaller “smoke” subsets vs. full-matrix runs, depending on intent.
Improved flake detection and auto-retry
  • Identify flaky jobs and differentiate infrastructure issues from real regressions.
  • Support smart retries and stability tracking (e.g., a “flakiness score” per job/test).
Automated regression bisect and triage
  • When a new failure appears, help guide maintainers toward a bisect workflow.
  • Tight coupling of KernelCI testing with bisection can reduce time-to-culprit for regressions.
Issue tracking integration
  • Use KCIDB issue data to surface known build/boot problems.
  • Allow tagging known issues, suppressing noise, and linking failures to external bug IDs.
  • Help maintainers prioritize new regressions over ongoing known failures.

3. Improved Results Visualization & Analysis

Rich CLI output and optional TUI mode
  • Improve terminal presentation of results beyond tables and colors.
  • Consider a text-based UI for interactive browsing of trees, commits, platforms, and results.
Enhanced diffing of test runs
  • Provide more detailed comparisons between runs:
    • which tests/platforms regressed
    • which ones improved
    • what stayed the same
  • Make it easy to answer: “Did my patch series introduce new failures?”
Dashboard navigation from the CLI
  • Provide convenient navigation from CLI output to the corresponding dashboard details for deep investigation.
  • Useful for sharing results and for quick jumps to logs/artifacts.
Performance and caching of results
  • Address slow fetching caused by large result payloads.
  • Add caching and incremental refresh so repeated queries become fast and practical for frequent use.
Customizable reports and notifications
  • Generate reports in formats suitable for email and meetings (e.g., Markdown or HTML).
  • Integrate with notification systems (email or chat) to alert on new failures or regressions.
  • Support targeted alerts, such as per-subsystem or per-platform summaries.

4. Integration with Patchwork, b4, and Git Hosting CI

Patch series injection (no public git required)
  • Allow developers to submit a patch series directly for KernelCI testing without pushing to a remote repository.
  • Treat a patch series as a first-class test input (alongside git trees), with clear provenance:
    • base commit and base tree selection
    • series identity (revision, hashes)
    • reproducible re-runs of the same exact series
  • Produce a reply-ready summary that maintainers can copy into mailing list threads or merge request discussions.
Patchwork integration for mailing-list patches
  • Fetch a patch series from Patchwork and trigger KernelCI testing on it.
  • Optionally report status back into Patchwork (as checks or comments), if policy and auth allow.
  • Bridge the gap for maintainers who work primarily via mailing lists.
b4 workflow support
  • Support workflows where a series is fetched from public mailing list archives and tested.
  • Reduce manual “git am” steps and shorten the path from email → test results.
GitLab CI / GitHub integration
  • Provide standard integration patterns for:
    • triggering KernelCI from pipelines
    • waiting for results
    • reporting pass/fail back into merge request / pull request context (status checks, comments)
Bi-directional tool integration
  • Minimize context switching for maintainers by integrating common tools:
    • patch tracking (Patchwork)
    • email-based series fetching (b4)
    • bug trackers (optional linking and evidence export)

5. Catering to Maintainers and Patch Submitters

Maintainer-focused features
  • Multi-tree / multi-branch dashboards and summaries to avoid missing failures.
  • Subsystem-focused filtering to highlight failures relevant to a maintainer’s area.
  • Release readiness tools (e.g., unresolved failures during an RC cycle) as practical checklists.
Developer-focused features
  • Quick pre-submit testing to catch regressions before sending patches.
  • Lightweight setup for read-only usage.
  • “Dry-run” style previews to estimate what a test plan would run and why.
Collaborative workflows
  • Easy export of results (structured data plus human-readable summaries) for sharing.
  • “Evidence bundles” to share logs and metadata with developers, maintainers, and infra teams.

6. Library, Packaging, and Extensibility

Library mode (SDK-style)
  • Provide a stable, documented Python library interface that exposes the same core capabilities as the CLI.
  • Make it straightforward for other tools and services to reuse kci-dev functionality:
    • CI integrations
    • dashboards
    • patch workflow automation
    • custom triage tooling
  • Keep the CLI as a thin wrapper over the library to reduce duplication and improve testability.
Packaging and distribution
  • Make installation easy and reproducible across environments.
  • Ensure compatibility with common distro workflows and secure update practices.
Plugin-friendly architecture
  • Consider a plugin mechanism so third parties can extend kci-dev without forking:
    • org-specific workflows
    • lab-specific metadata mapping
    • custom result views and reports
    • alternative backends (where appropriate)

7. Addressing Pain Points & Ongoing Improvements

Patchwork integration as a high priority
  • A commonly requested gap in mailing-list-centric workflows.
  • Closing this loop makes KernelCI substantially more useful to maintainers.
Performance and usability
  • Caching and incremental updates reduce friction for frequent triage.
  • Better error messages, shell completions, and documentation reduce onboarding time.
Roadmap alignment
  • Prioritize foundational improvements like git context awareness and regression diffing.
  • Expand toward richer automation once the “fast path” experience is solid.
Community and extensibility
  • Encourage community contributions around org-specific workflows and lab integrations.
  • Maintain clear boundaries between core features and optional extensions.

Conclusion

These ideas aim to make kci-dev a practical day-to-day tool for kernel work: fast access to results, strong regression signal, smooth integration with mailing lists and Git-based workflows, and scalable triage for maintainers responsible for multiple trees and platforms.
