The Design and Implementation of the RT-Thread Operating System

WebThread scheduling policies Linux uses three main thread scheduling policies. SCHED_OTHER (sometimes called SCHED_NORMAL ) This is the default thread policy and has dynamic priority controlled by the kernel. The priority is changed based on thread activity. Threads with this policy are considered to have a real-time priority of 0 (zero). WebThe general idea of RT Linux is that a small real-time kernel runs beneath Linux, meaning that the real-time kernel has a higher priority than the Linux kernel. Real-time tasks are executed by the real-time kernel, and normal Linux programs are allowed to run when no real-time tasks have to be executed.

WebWith RTAI, the thread waiting and posting a semaphore however needs to be in real-time context. This means that using RTAI's named semaphore means switching between real-time and non-real-time context on every wait/post in user space, and worse, creating a short real-time thread for every sem/wait in kernel space.
