"Linux/RT is a tool for developing and testing embedded and non-embedded real-time applications. TimeSys, the maker of Linux/RT, suggested several application domains where Linux/RT could be used. Application domains suggested include industrial automation, process control, telecommunications, web servers, avionics and others."

"According to the vendor, the architecture of Linux/RT offers Linux resilience and stability while running real-time applications. To make the architecture real, TimeSys added a few additional calls to their release of Linux and used a real-time resource kernel (RK). As a loadable kernel module (LKM), the real-time RK interacts with the Linux kernel. The Linux kernel interacts with the hardware. Using this architecture, the resource kernel can take advantage of all existing Linux hardware drivers. Existing applications continue to interact with the Linux kernel, while real-time applications interact with the real-time kernel module. With this approach, the whole system will not crash if a real-time application process hangs or crashes. It also means pre-existing (legacy) Linux applications can run along side the real-time application. The RK module may be loaded or unloaded like any other LKM."
