What is priority inversion?
Priority inversion is a situation where in lower priority tasks will run blocking higher priority tasks waiting for resource (mutex). For ex: consider 3 tasks. A, B and C, A being highest priority task and C is lowest. Look at sequence of context swaps A goes for I/O . unlocks mutex. C was ready to run. So C starts running. locks mutex B is ready to run. Swaps out C and takes mutex. A is ready to run. but A is blocked as mutex is locked by B. but B will never relinqishes the mutex as its higher priority than C. The solution to priority inversion is Priority inheritance.
When processes share a semaphore variable mutex?
