Apr 1, 2026April 2026 monthly summary for qualcomm-linux/meta-qcom. The team delivered targeted multimedia image support and strengthened CI/reproducibility, enhancing our product’s media capabilities while reducing risk in builds and tests across QoQ release cycles. Key outcomes include the introduction of a multimedia-focused image path (qcom-multimedia-image) with a lightweight configuration, enabling customers to deploy media-heavy workloads without pulling in proprietary/container images. This was implemented through a dedicated Kas configuration and CI workflow adjustments (commits: 7f142b014e3d357f928ebbcd175ab3221fe4669e; 1ae4975eb282f442bebbd51d4223b74512ce8f60). We also fixed distro name usage for the qcom-armv7a workflow to align with LAVA test plans and artifact fetch expectations, preventing test/job failures (commit: 900f77f8be62bac7589f62e591eccaf16b396416). In addition, CI stability and reproducibility were significantly enhanced: consolidated qcom-distro targets into qcom-distro.yml, pinned external layers for reproducible builds, and added explicit CI parameters. This included: locking upstream layers (base.lock.yml) and making repo branch definitions explicit (commits: 23e5a455e5c09e87bdf2e33e31ce6baf4abbfdc4; d419bc7fd177920b74ae9e64c234e31dff6eeaa5; 6292cb2f3c9aa3d98a8feb7b884f90aff8052783). Overall impact: faster, more reliable multimedia image builds; improved test plan compatibility; and deterministic CI workflows, reducing breakages during releases. Demonstrates strong capabilities in Yocto/Kas-based image configuration, CI/CD orchestration, and upstream dependency management.

Mar 1, 2026March 2026: Delivered reliability, portability, and CI improvements for qualcomm-linux/meta-qcom. Key features include a systemd oneshot service that auto-formats the /var/lib/tee partition to ext4 during early boot, ensuring a valid filesystem for encrypted data and reliable dependent services. This reduces boot-time failures and data-path risk for QTEE. Major bug fix addressed ISO C23 conformance for strrchr() to support glibc 2.43, resolving build portability issues in qc-image-unpacker. CI/build improvement updated the RT 6.18 default to qcom-distro-kvm, enabling broader latency testing under KVM. Accomplishments also include patching for architecture-specific tooling and aligning the CI matrix with RT kernel testing goals.
