摘要： Techniques for simulating exclusive use of a processor core amongst multiple logical partitions (LPARs) include providing hardware thread-dependent status information in response to access requests by the LPARs that is reflective of exclusive use of the processor by the LPAR accessing the hardware thread-dependent information. The information returned in response to the access requests is transformed if the requestor is a program executing at a privilege level lower than the hypervisor privilege level, so that each logical partition views the processor as though it has exclusive use of the processor. The techniques may be implemented by a logical circuit block within the processor core that transforms the hardware thread-specific information to a logical representation of the hardware thread-specific information or the transformation may be performed by program instructions of an interrupt handler that traps access to the physical register containing the information.
