Summary:The stack resource policy (SRP) is a resource allocation policy which permits processes with different priorities to share a single runtime stack. It is a refinement of the priority ceiling protocol (PCP), which strictly bounds priority inversion and permits simple schedulability tests. With or without stack sharing, the SRP offers the following improvements over the PCP: (1) it unifies the treatment of stack, reader-writer, multiunit resources, and binary semaphores; (2) it applies directly to some dynamic scheduling policies, including earliest deadline first (EDF), as well as to static priority policies; (3) with EDF scheduling, it supports a stronger schedulability test; and (4) it reduces the maximum number of context switches for a job execution request by a factor of two. It is at least as good as the PCP in reducing maximum priority inversion
