Laura Baird, Neelesh Reddybattula, Nazanin Siavash, Terrance E. Boult, Armin Moin
TL;DR
TianoCore bug reports can omit structured firmware diagnostics that affect triage, motivating a revised EDK II template. The paper analyzes issues, proposes explicit fields and advisory AI comments, and finds that regression and architecture information justify structured fields while pilot interviews inform the design.
Problem
The paper asks how to adapt TianoCore’s bug-report structure for effective and efficient triage and resolution amid often-omitted structured diagnostic information.
Method
It manually analyzes 92 EDK II bug reports, proposes explicit firmware-specific fields and AI-generated advisory comments, and develops a prototype for community validation.
Results
Regression and architecture information occur often enough in 92 EDK II issues to justify structured fields, while pilot interviews provide formative feedback on the proposed representation.
Takeaways & Limitations
The proposed EDK II template makes firmware-specific diagnostic fields explicit and integrates advisory AI comments for bug triagers and fixers.
Takeaways & Limitations
The study remains work-in-progress, with larger interviews and validation of AI-generated advisory comments still planned.
Abstract
from arXiv · showhide
We propose enhancing the bug report templates in the GitHub Issues issue tracking system used by the TianoCore open-source community with the aim of improving the bug triage and resolution process. We analyze the bug repository data and find patterns of information that are useful for bug triage and fixing. However, some of them are only occasionally included in the free-form text of bug reports. Therefore, we propose adding a few new fields to the existing TianoCore bug report template. In this study, we focus on the key TianoCore project, EDK II, which constitutes the core of the UEFI firmware across various firmware vendors and original equipment manufacturers. This study is currently a work-in-progress. So far, we have interviewed a few developers to obtain their feedback and adjust the proposed approach. We are planning more interviews with the TianoCore community to conduct A/B tests and validate our approach to achieve effective and efficient bug triage and resolution.
1 Introduction
The paper addresses incomplete and poorly structured firmware bug reports by proposing enhanced EDK II issue templates, AI-assisted triage, and a web-based validation prototype. It focuses on improving bug triage and resolution in the TianoCore EDK II ecosystem.
- Motivation: Developers value structured evidence in bug reports, but reporters often omit or bury it in free-form text, creating costly challenges for firmware projects.Relevant evidence includes reproduction steps, stack traces, and test cases.
- Context: EDK II is an open-source UEFI reference implementation used across many firmware vendor stacks, and its issue tracking has migrated from Bugzilla to GitHub Issues.The paper targets this ecosystem to improve security and software maintenance workflows.
- Contributions: The paper proposes adding predefined fields to EDK II bug reports to guide more complete issue creation and improve triage and bug-fixing effectiveness and efficiency.The proposed fields are intended to make bug reports better structured.
- Contributions: It also proposes GPT-based generative AI assistance for human triagers and presents a web-based prototype for large-scale evaluation with TianoCore developer feedback.The AI component would generate advisory comments for triagers.
- Paper organization: The paper reviews related work, presents its approach and preliminary validation results, and concludes with future work.These topics are covered in Sections 2 through 5, respectively.
2 Related Work
Prior research shows that bug-report information affects debugging outcomes and that developers and reporters may disagree about which information is useful or easy to provide. Related work also examines GitHub templates, missing-information detection, and semi-automated bug triage.
- Developers and bug reporters often disagree about which bug-report information is most useful and easiest to provide.
- Reproduction steps and stack traces affect debugging and resolution outcomes, while other techniques detect missing information and assess reproduction-step quality.
- GitHub issue templates can improve report comprehensibility and consistency, but their effects on discussion and resolution processes are nuanced.
- Prior MSR research addresses bug triage tasks including invalid and duplicate detection, assignee recommendation, and severity prediction.
3 Proposed Approach
The proposed approach augments TianoCore bug reports with domain-specific diagnostic fields and AI-generated advisory comments. It preserves human review while adding confidence scores and explanations to support triage and issue handling.
- Diagnostic fields: The template adds an impacted-architectures field with selectable options and a free-form field describing behavior differences across architectures.Options include IA32, X64, AARCH64, LOONGARCH64, ARM, RISCV64, and Not sure.
- Diagnostic fields: The architecture information helps triagers identify affected architectures and distinguish architecture-specific failures from general bugs.It may also help ecosystem companies assess issue relevance to their repositories.
- Diagnostic fields: An issue-category field distinguishes software defects, feature requests, and specially handled issues such as security vulnerabilities.Security vulnerabilities follow a separate process from non-security issues in TianoCore.
- AI-assisted triage: AI-generated advisory comments automatically add triage information while remaining distinguishable from original reports and subject to developer review and feedback.Bug triagers, package maintainers, and bug fixers review the generated information, and their feedback is looped into future improvements.
- AI-assisted triage: A confidence score is provided before human review, while reviewer feedback is used to adjust and enhance the AI-based feature.The reviewing users include triagers, fixers, and maintainers.
- AI-assisted triage: Pilot interviews favored explainable AI recommendations, so each advisory comment includes evidence and justification for suggested tags, priority levels, or assignees.Examples draw on bug-report information and historical repository data.
4 Preliminary Results
Preliminary results combine manual analysis of 92 EDK II bug reports with four pilot interviews to assess richer bug-report structures. The analysis identifies architecture information as potentially triage-relevant, while most interview participants preferred a modified template with additional fields and AI support.
- 4 Preliminary Results: The study manually analyzed 92 closed, type:bug-labeled EDK II GitHub-native issues from a documented repository snapshot.TianoCore had migrated from Bugzilla to GitHub Issues.
- 4 Preliminary Results: Four pilot interviews used a within-subjects A/B comparison of paired real EDK II issues shown as Template 1 and Template 2.Participants reviewed the blinded representations and answered on-screen and verbal follow-up questions about usefulness, missing information, structure, and presentation.
- 4 Preliminary Results: 35 out of 92 bug reports mentioned architecture information, including 16 using it in trigger-specific or root-cause-specific ways.The passage presents architecture as more than background context because it can affect how bugs are understood.
- 4 Preliminary Results: 11 out of 92 issues were labeled as regressions in the selected corpus.These frequencies were reported alongside the architecture-related findings.
- 4 Preliminary Results: Three out of four participants preferred the modified version with additional fields and AI support, while the more experienced participant preferred the concise version.The interviews were conducted through video calls using a web-based prototype.
5 Conclusion and Future Work
The paper proposes a structured TianoCore EDK II bug-report template that makes firmware-specific diagnostics explicit and integrates advisory AI comments. Future work will expand developer interviews, validate AI comment quality across roles, and improve rapid issue scanning.
- Conclusion: The proposed EDK II template makes firmware-specific diagnostic fields explicit and integrates advisory AI comments for bug triagers and fixers.Manual analysis of 92 EDK II issues found regression and architecture information frequent enough to justify structured fields.
- Conclusion: Pilot interviews provided formative feedback on the new structured bug-report representation.The study remains work-in-progress.
- Future Work: Future work will conduct larger-scale interviews with TianoCore developers using the demonstrated web-based prototype.These interviews are intended to support further validation of the approach.
- Future Work: The study will validate AI-generated advisory comment quality with bug triagers, bug fixers, and package maintainers.Validation will involve developers in various roles.
- Future Work: Future iterations will present each recommendation and linked supporting evidence before model-identification details to support rapid issue scanning.The planned ordering is intended to make recommendations and their evidence easier to scan quickly.
