APPARATUS AND METHOD FOR MULTI-THREADED PROCESSORS PERFORMANCE CONTROL |
摘要 |
A power management technique uses system management interrupt (SMI) to manage performance states of logical processors in a physical processor. Each logical processor is associated with a virtual performance state and an actual performance state. A request to retrieve or to change the virtual performance state causes the SMI to be generated. The virtual performance state is a state known to an operating system (OS). The actual performance state is a state that the logical processor is operating at. |
