摘要： A mechanism is provided in a logically partitioned data processing system for controlling depth and latency of exit of a virtual processor's idle state. A virtualization layer generates a cede latency setting information (CLSI) data. Responsive to booting a logical partition, the virtualization layer communicates the CLSI data to an operating system (OS) of the logical partition. The OS determines, based on the CLSI data, a particular idle state of a virtual processor under a control of the OS. Responsive to the OS calling the virtualization layer, the OS communicates the particular idle state of the virtual processor to the virtualization layer for assigning the particular idle state and wake-up characteristics to the virtual processor.

摘要： A method, system and computer-usable medium are disclosed for managing power consumption in information processing systems. Processing resources are successively folded, allowing them to be placed into deeper and deeper power saving states while maintaining the ability to respond to new processing loads without exposing the latency of the deeper power saving states as they are unfolded. Before a deeper power saving state can be used, there must be sufficient processing resources in the prior power saving state to mask the latency of bringing a processing resource out of the deeper power saving state.
摘要翻译：公开了一种用于管理信息处理系统中的功耗的方法，系统和计算机可用介质。处理资源被连续地折叠，使得它们能够被放置在更深和更深的省电状态，同时保持对新的处理负载的响应能力，而不会暴露更深的省电状态在其展开时的延迟。在可以使用更深的省电状态之前，在现有的省电状态下必须有足够的处理资源，以掩盖使处理资源脱离更深的省电状态的延迟。

摘要： A mechanism is provided for directed resource folding for power management. The mechanism receives a set of static platform characteristics and a set of dynamic platform characteristics for a set of resources associated with the data processing system thereby forming characteristic information. The mechanism determines whether one or more conditions have been met for each resource in the set of resources using the characteristic information. Responsive to the one or more conditions being met, the mechanism performs a resource optimization to determine at least one of a first subset of resources in the set of resources to keep active and a second subset of resources in the set of resources to dynamically fold. Based on the resource optimization, the mechanism performs either a virtual resource optimization to optimally schedule the first subset of resources or a physical resource optimization to dynamically fold the second subset of resources.

摘要： A mechanism is provided for transparently consolidating resources of logical partitions. Responsive to the existence of the non-folded resource on an originating resource chip, the virtualization mechanism determines whether there is a destination resource chip to either exchange operations of the non-folded resource with a folded resource on the destination chip or migrate operations of the non-folded resource to a non-folded resource on the destination chip. Responsive to the existence of the folded resource on the destination resource chip, the virtualization mechanism transparently exchanges the operations of the non-folded resource from the originating resource chip to the folded resource on the destination resource chip, where the folded resource remains folded on the originating resource chip after the exchange. Responsive to the absence of another non-folded resource on the originating resource chip, the vitalization mechanism places the originating resource chip into a deeper power saving mode.

摘要： A mechanism is provided for temporarily allocating dedicated processors to a shared processor pool. A virtual machine monitor determines whether a temporary allocation associated with an identified dedicated processor is long-term or short-term. Responsive to the temporary allocation being long-term, the virtual machine monitor determines whether an operating frequency of the identified dedicated processor is within a predetermined threshold of an operating frequency of one or more operating systems utilizing the shared processor pool. Responsive to the operating frequency of the identified dedicated processor failing to be within the predetermined threshold, the virtual machine monitor either increases or decreases the frequency of the identified dedicated processor to be within the predetermined threshold of the operating frequency of the one or more operating systems utilizing the shared processor pool and temporarily allocates the identified dedicated processor to the shared processor pool.
