Dec 1, 2025December 2025 (Samsung/TizenRT): Delivered reliability, observability, and developer-productivity improvements across core subsystems. Key outcomes include: (1) robust semaphore handling with EINTR retry and improved critical section protections; (2) timer tick processing made PM-agnostic for consistent up_timerisr behavior; (3) explicit I2C timeout logging across architectures; (4) clearer UART driver registration logs with differentiated success/failure paths; (5) robust power command argument parsing for long-term test workflows. Together, these changes reduce runtime failures, improve debuggability, and accelerate validation in power-managed environments and driver stacks, demonstrating strong low-level kernel, driver, and debugging skills.
