kci-bisect

A generic toolbox for automated Linux kernel bisection.

This project provides composable building blocks for bisecting kernel issues of the different types, for example:

• build failures
• boot failures
• configuration failures
• unit test failures
• performance regressions

The components are designed to be usable standalone or integrated into CI systems such as KernelCI.

Status

Early development. We are collecting existing bisection tools and approaches from multiple organisations and refactoring them into reusable components. Contributions are welcome.

Goals

• Generic bisection framework
• Composable building blocks:
  • build
  • test
  • cache
  • results parsing
  • results verification
  • results analysis
  • reporting
• Support for reproducible builds (TuxMake) and tests (TuxRun)
• Pluggable backends for build and test execution
• Pluggable frontends for reporting
• Usable both as a CLI tool(s) and as a library

Contributing

We are actively looking for existing bisection tools. Please drop them into contrib/ with a short README describing what they do and how they work.

See the GitHub issues for the current roadmap and discussion topics. Design sketch in docs/architecture.md; unresolved design questions in oq.md.
