Research and Realization of Priority Inheritance Applied in Linux Kernel Semaphore
优先级继承运用于Linux内核信号量的研究与实现

It is very important to solve the problem of priority inversion by means of priority inheritance when applying Linux in real-time embedded system. Based on the analysis of the Linux source codes about kernel semaphore operation, this paper realizes the base priority inheritance protocol by modifying the Linux kernel, and passes the test on the embedded system of PCM-3350.
