What is priority inversion?

Can you explain what priority inversion is?

Priority inversion occurs when a lower-priority task holds a resource needed by a higher-priority task, causing delays.

How does it affect real-time systems?

In real-time systems, priority inversion can lead to missed deadlines, as high-priority tasks may be blocked by lower-priority ones.

Are there any solutions to prevent priority inversion?

Yes, solutions include priority inheritance, where the lower-priority task temporarily inherits the higher priority.

Can you give an example of priority inversion in a program?

Sure! Imagine a high-priority task waiting for a mutex held by a low-priority task, which is preempted by a medium-priority task.
