Mar 1, 2026Monthly summary for 2026-03 focusing on delivering business value and technical achievements within qualcomm-linux/meta-qcom. 1) Key features delivered - QCOM Ptool Revision Update: Partition Management and Platform Configurations. Updated qcom-ptool revision to enable advanced partition management, add --phys-part flag, and revamp partition handling across platforms. Also updated contents.xml.in metadata (meta_type/build_type) and platform support (e.g., iq-8275-evk, qcs8275-monza/emmc). This enables more flexible, accurate build-time partitioning and platform configuration for current and upcoming devices. - CI/CD Improvements: Build summaries, artifact handling, and cleanup. Introduced a reusable build summary action, migrated to hosted runners for this task, and added robust cleanup of sstate caches, with improved handling for long-running cleanups and typo fixes in input parameters. 2) Major bugs fixed - Partition tooling stability: fixes in gen_partition parsing and partition_entries handling; revamps to parts data, improving reliability of partition generation and preventing misconfigurations on multiple devices. - CI reliability: fixes to ensure summary generation works only when artifacts exist and to publish summaries for all successful builds, improving visibility even when some builds fail; corrected action input naming typos to avoid workflow failures. 3) Overall impact and accomplishments - Increased platform readiness: broader support for newer Qualcomm platforms with more accurate partition configurations, enabling faster integration cycles and fewer manual interventions. - More reliable, cost-efficient CI: predictable monthly cache cleanup, reduced runner costs, and stable build summaries, leading to faster feedback and reduced operational risk. - Improved transparency: consistent visibility into build health and artifact status across the pipeline, aiding decision-making and release readiness. 4) Technologies/skills demonstrated - qcom-ptool, gen_partition, and partition management techniques; platform configuration across partitions and EMMC. - CI/CD automation with GitHub Actions, reusable actions, hosted runners, sstate/cache management, and robust summary reporting. - DevOps practices: artifact handling, cache lifecycle management, and performance optimization for large-scale builds. Top achievements: - Delivered QCOM Ptool revision enabling partition management and platform configuration improvements. - Implemented reusable CI/CD build summary action with hosted runners and improved cache cleanup, reducing cost and increasing reliability. - Ensured build summaries reflect all successful builds, improving visibility for release decisions. - Optimized monthly cache cleanup time and cost by using appropriate runners and timeout adjustments. - Standardized tooling across meta-qcom-distro workflows to reduce duplication and manual steps.
