摘要：
A mechanism is provided for controlling power management policies on a per logical partition basis. A power management mechanism in a data processing system receives a notification that the logical partition has been generated, a set of processing units associated with the logical partition, and a current power management policy to be implemented for the logical partition. The power management mechanism adds the logical partition and the set of processing units to a list of logical partitions. The power management mechanism initializes the set of processing units based on settings for the set of processing units in the current power management policy. The power management mechanism notifies a virtualization mechanism that the set of processing units are running at a specified performance level in order for the logical partition to start executing tasks on the set of processing units.
