Worked on the avocado-framework/avocado-vt repository, delivering features and fixes to enhance virtualization workflows and test reliability. Developed a configurable controller bus for PCI slot discovery, enabling flexible VM configurations and reducing manual setup by updating PCI slot allocation logic using Python and system programming techniques. Introduced targeted PF PCI ID retrieval to support deterministic SR-IOV test scenarios, improving device management and system testing capabilities. Addressed coverage analysis reliability by relocating LCOV output files and extending coverage collection tooling to handle long file paths and additional options, resulting in more stable CI integration and trustworthy coverage metrics across diverse environments.

Mar 1, 2026March 2026 — avocado-vt: Reliability improvements to LCOV coverage collection under long file path scenarios. The output file was relocated from test_result/test_debugdir to test_result to avoid path-length failures, and the coverage collection function was extended to accept extra_opts for additional LCOV options. This fixes a known CI flake and enhances coverage reporting consistency across environments. The fix is implemented in commit fde3ec4c9d65bd379d576e207de7f01d9538aea1 and signed off by Yingshun Cui. Impact: more stable and trustworthy coverage metrics, faster diagnosis of coverage-related issues, and smoother CI integration. Technologies demonstrated: Python tooling for coverage collection, LCOV integration, file I/O and path handling, and parameterization of tooling."

Jun 1, 2025June 2025 monthly summary for avocado-framework/avocado-vt. Focused on delivering a targeted PF PCI ID retrieval feature to improve deterministic test scenarios and support targeted PF selection in get_pf_pci. No major bug fixes reported this month; all efforts aligned with enhancing test reliability and business value. Key deliveries included a new test_pf parameter to get_pf_pci enabling retrieving the PCI ID of a specific PF. Commit reference: 665a20a36366c3f6a8f444613f852643ec78c46c (sriov: Add a parameter to get the specified PF).

Jan 1, 20252025-01 Monthly Summary for avocado-vt: Implemented a configurable controller bus for PCI slot discovery to overcome hardcoded limitations and enable flexible VM configurations. The change updates get_free_pci_slot to accept a configurable controller bus value, supporting PCI slot allocation across multiple controllers. This delivers greater deployment scalability, reduces manual configuration overhead, and improves maintainability in virtualization workflows. Linked to commit f29de51f410be70cdb4856651cc64c396a4de529 ("get_free_pci_slot: Make the value of controller bus configurable").
