Abstract: A method and system for managing a power state of a processor are described herein. The method includes receiving, at the processor, a signal indicating that an interrupt is to be sent to the processor. The method also includes transitioning the processor from the deep idle state to the shallow idle state in response to receiving the signal and transitioning the processor from the shallow idle state to an active state in response to receiving the interrupt.

Abstract: Methods and apparatus for facilitating efficient Quality of Service (QoS) support for software-based packet processing by offloading QoS rate-limiting to NIC hardware. Software-based packet processing is performed on packet flows received at a compute platform, such as a general purpose server, and/or packet flows generated by local applications running on the compute platform. The packet processing includes packet classification that associates packets with packet flows using flow IDs, and identifying a QoS class for the packet and packet flow. NIC Tx queues are dynamically configured or pre-configured to effect rate limiting for forwarding packets enqueued in the NIC Tx queues. New packet flows are detected, and mapping data is created to map flow IDs associated with flows to the NIC Tx queues used to forward the packets associated with the flows.

Abstract: Examples are disclosed for determining or using server transaction latency information. In some examples, a network input/output device coupled to a server may be capable of time stamping information related to ingress request and egress response packets for a transaction. For these examples, elements of the server may be capable of determining transaction latency values based on the time stamped information. The determined transaction latency values may be used to monitor or manage operating characteristics of the server to include an amount of power provided to the server or an ability of the server to support one or more virtual servers. Other examples are described and claimed.

Abstract: Methods and systems may provide for determining a plurality of buffer-related settings for a corresponding plurality of idle states and outputting the plurality of buffer-related settings to a device on a platform. The device may determine an observed bandwidth for a channel associated with a receive buffer and identify a selection of a buffer-related setting from the plurality of buffer-related settings based at least in part on the observed bandwidth. In one example, each buffer-related setting includes a latency tolerance and a corresponding idle duration.
