Priority inversion is a critical and well-known problem in real-time systems. It occurs when a high-priority task is delayed or blocked by a lower-priority task. Priority inversion can lead to system failures as high-priority tasks may not be able to complete their critical tasks in a timely manner.
There are several techniques that can be used to avoid priority inversion. One common technique is to use priority inheritance. Priority inheritance is a mechanism that allows a task to temporarily inherit the priority of a higher-priority task that is waiting for a resource. This ensures that the higher-priority task is not blocked by the lower-priority task.
