PREEMPT_RT
A real-time patch for the Linux kernel that gives Linux hard real-time capability. It is used in robotics and other scenarios with strict requirements for deterministic latency.
Timeline (last 90 days)
Typical implementations of real-time control rely on real-time operating systems (such as FreeRTOS, Linux with the PREEMPT_RT patch), deterministic communication (such as EtherCAT, CAN bus), and periodic control loops (commonly 100Hz–1kHz).
Multi-kernel architecture allows one kernel to be dedicated to running real-time tasks (such as a PREEMPT_RT kernel) while another handles general-purpose workloads, enabling mixed deployment of real-time and general-purpose systems.
