Abstract:
A computer implemented method for control access to a contested resource. When a lock acquisition request is received from a virtual machine, the partition management firmware determines whether the lock acquisition request is received within a preemption period of a time slice allocated to the virtual machine. If the lock acquisition request is received within the preemption period, the partition management firmware ends the time slice early, and performs a context switch.
