Abstract

Technologies for processor core soft-offlining include a computing device having a processor with multiple processor cores. On boot, an operating system queries a firmware interface to retrieve a potential offline set of processor cores. The operating system prevents the processor cores of the potential offline set from receiving device interrupts. The computing device detects a platform management event from the firmware interface and, in response to the platform management event, queries the firmware interface to determine a requested offline set of processor cores. Each of the processor cores in the requested offline set is included in the potential offline set. The computing device brings the processor cores of the requested offline set into a low-power state, and then the computing device may start performing a platform management operation. The platform management event may include a memory hot-plug event or a specialized workload event. Other embodiments are described and claimed.
