Dec 1, 2025December 2025 Monthly Summary (lf-edge/eve) Key features delivered - USB boot order configurability in UEFI firmware and QEMU guests: Introduced EveBootOrderLib to read fw_cfg opt/eve.bootorder, log boot options, and adjust USB entries based on usb/nousb values; updated UEFI-related tooling for QEMU guests via a new eve-uefi image that supports USB configurations. Commits include 947452cf722f333b2981b82dc2a837960cd969d5 and b46397439661b94768fa5957da3417ffa2b60c8b. Major bugs fixed - VM boot retry reliability: Ensured globalConfig is passed to the hypervisor Setup function during maybeRetryBoot, fixing memory limit misconfigurations and VNC access issues on restarts. Commit: 974ec20fb040087c012beec4c962207af0f71ba5. Overall impact and accomplishments - Improved boot determinism and user control for VM boot sequences, reducing retry failures and making VM restarts more reliable in EVE environments. Enabled safer, more predictable memory handling and VNC access for container workloads. Technologies/skills demonstrated - UEFI firmware extension and fw_cfg integration, EveBootOrderLib development, UEFI image/containers (eve-uefi) creation, XEN-tools Dockerfile alignment with UEFI features, and hypervisor configuration integration in restart paths. Demonstrated robust patching, observability of boot options, and end-to-end feature delivery that adds direct business value by improving boot reliability and configurability.

Sep 1, 2025In Sep 2025, delivered a reliability-focused bug fix for lf-edge/eve: persistent configuration on skip. Ensured lastconfig is persisted to disk even when inhaleDeviceConfig updates are skipped, eliminating stale checkpoints and reducing risks of spurious downloads or unintended downgrades after reboot. This improves device resilience, network efficiency, and user experience. Implemented via pillar/zedagent change; commit 2a0e01a6fa582c9f06e382ce0aaa5973161255f4.
