<h1>Kernel API</h1>
The openvela kernel is based on Apache NuttX RTOS and provides POSIX-compliant system interfaces covering process/thread management, task scheduling, memory management, signal mechanisms, message queues, and other core functionalities. This section provides detailed API references and usage instructions for each kernel subsystem.
