Sep 1, 2025Summary for 2025-09 (canonical/checkbox): Delivered two major features that expand validation coverage and streamline test automation. NVIDIA graphics validation and DRM modeset test coverage introduce a Python-based workflow that gathers graphics information, verifies the proprietary NVIDIA driver is enabled, and ensures DRM modesetting is active; includes test plans and manifests to validate NVIDIA rendering and integrates a new NVIDIA DRM test plan into the OEM CE provider to improve display/graphics coverage. RPMSG testing framework overhaul refactors tests by consolidating into rpmsg_tests.py, removes legacy rpmsg_load_firmware.py, and enhances sysfs handling and argument parsing for better test management. These efforts improve hardware validation coverage, reduce maintenance, and enable faster CI feedback.

Feb 1, 2025February 2025: Focused on reliability and test-readiness for the canonical/checkbox repo. Delivered a stability improvement by increasing SNAPD_TASK_TIMEOUT to 600 seconds for checkbox-ce-oem snaps across multiple series, addressing task execution duration issues and boosting overall reliability. Also introduced comprehensive test-case documentation for ce-oem-provider, detailing purposes, environment variables, file locations, and commands for tests across components (crypto, digital I/O, ethernet, GPIO, IIO sensors, MIR, OPTEE, OTG, RPMSG, serial, SPI, stress, strict confinement, video codecs) to guide test configuration and future automation. These changes align with business goals of stable deployments and faster QA cycles.
