Annotated Snippet

# This config fragment enables coverage on UML, which is different from the
# normal gcov used in other arches (no debugfs).
# Example usage:
# ./tools/testing/kunit/kunit.py run \
#   --kunitconfig=tools/testing/kunit/configs/all_tests_uml.config \
#   --kunitconfig=tools/testing/kunit/configs/coverage_uml.config

Annotation

• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
