A major drawback of RTOSes is the low latency response limitation. Even if these systems are called real time, due to their software stack they can only guarantee a response time of a few milliseconds. On a particular note, Tock, an embedded operating system written in Rust, that offers a high degree of security, by clearly separating kernel, drivers and userspace, suffers from a high performance penalty when it comes to real-time response. This presentation will show how eBPF has been introduced in Tock to greatly improve low-latency responses. Using this method, applications can submit arbitrary code to be run at kernel speed in a fully secure environment. This addition to Tock basically defines a third type of application that is neither a userspace program nor a driver. It has all the performance advantages of a driver, while obeying similar constraints to userspace applications. This work has been inspired by the usage of eBPF in the Linux kernel to obtain similar results for general purpose OSes and applications.
