Editing Priority inheritance (section)

{{Short description|Computer programming method}}In [[real-time computing]], '''priority inheritance''' is a method for eliminating unbounded [[priority inversion]]. Using this [[Computer programming|programming]] method, a [[process scheduling]] [[algorithm]] increases the priority of a process (A) to the maximum priority of any other process waiting for any [[resource (computer science)|resource]] on which A has a [[Lock (computer science)|resource lock]] (if it is higher than the original priority of A).

The basic idea of the priority inheritance protocol is that when a job blocks one or more high-priority jobs, it ignores its original priority assignment and executes its [[critical section]] at an elevated priority level. After executing its critical section and releasing its locks, the process returns to its original priority level.
