Abstract
A logical partition management apparatus and method for handling system reset interrupts (SRIS) are provided. The apparatus and method provide a SRI handler in the hypervisor that is capable of handling SRIs which may occur at any time during the operation of the multiprocessor computing system. The apparatus and method allow a hypervisor call to be completed before an SRI is handled. In this way, the SRI does not cause a processor of the symmetric multiprocessor (SMP) system to indefinitely hold a lock on a system resource and thus, other processors are not starved due to an inability to access the system resource.
