RT-Thread是一个来自中国的开源物联网操作系统，它提供了非常强的可伸缩能力：从一个可以运行在ARM Cortex-M0芯片上的极小内核，到中等的ARM Cortex-M3/4/7系统，甚至是多核，64位的ARM Cortex-A，MIPS32/64处理器的功能丰富系统

Linux in itself is not real time capable. With the additional PREEMPT_RT patch it gains real-time capabilities. The key point of the PREEMPT_RT patch is to minimize the amount of kernel code that is non-preemptible, while also minimizing the amount of code that must be changed in order to provide this added preemptibility. In particular, critical sections, interrupt handlers, and interrupt-disable code sequences are normally preemptible. The PREEMPT_RT patch leverages the SMP capabilities of the Linux kernel to add this extra preemptibility without requiring a complete kernel rewrite.
