摘要:
Automatically determining a link speed between link partners using a multispeed fiber module. An embodiment solves the problem of how to determine the highest common link speed between short range (SR)/long range (LR) fiber link partners when at least one of the link partners is using a multispeed fiber module. In an embodiment, a multispeed fiber module comprises a module that is capable of both 10 gigabit (GB) per second Ethernet and 1 GB per second Ethernet or lesser data transfer speeds over a fiber optical link. In an embodiment, the method comprises trying each link speed in a known succession, from highest supported speed to lowest supported speed. In an embodiment, an initiator link partner “blinks” a transmit laser, which alerts the link partners that a link speed determination session is being initiated. By automatically determining link speed, the user is relieved of the necessity to manually configure the link speed.

Methods, apparatus, and systems for facilitating effective power management through dynamic reconfiguration of interrupts. Interrupt vectors are mapped to various processor cores in a multi-core processor, and interrupt workloads on the processor cores are monitored. When an interrupt workload for a given processor core is detected to fall below a threshold, the interrupt vectors are dynamically reconfigured by remapping interrupt vectors that are currently mapped to the processor core to at least one other processor core, such that there are no interrupt vectors mapped to the processor core after reconfiguration. The core is then enabled to be put in a deeper idle state. Similar operations can be applied to additional processor cores, effecting a collapsing of interrupt vectors onto fewer processor cores. In response to detecting cores emerging from idle states, reconfiguration of interrupt vectors can be performed to rebalance the assignment of the vectors across active cores by remapping a portion of the vectors to those cores.
摘要:
Generally, this disclosure describes a network controller for remote system management. A host device may include the network controller and a programmable network element. The network controller may include controller circuitry configured to acquire network management data related to operation of the network controller and to receive host management data related to operation of the host device. The network controller may further include a transmitter configured to transmit the network and host management data to a management system remote from the network controller and a receiver configured to receive a command from the management system related to the management data, the command configured to reprogram the programmable network element to change a behavior of the programmable network element.
摘要:
Examples are disclosed for a device having at least two media access controllers. In some examples, a first media access controller may be coupled to a host computing device. A second media access controller may be coupled to one or more processor circuits arranged to perform packet processing of data payloads for one or more data frames forwarded through the first media access controller and/or forwarded through the second media access controller. The first media access controller may be coupled to the second media access controller via a communication link. Other examples are described and claimed.

Described are embodiments of mediums, methods, and systems for application-reserved use of cache for direct I/O. A method for using application-reserved cache may include reserving, by one of a plurality of cores of a processor, use of a first portion of one of a plurality of levels of cache for an application executed by the one of the plurality of cores, and transferring, by the one of the plurality of cores, data associated with the application from an input/output (I/O) device of a computing device directly to the first portion of the one of the plurality of levels of the cache. Other embodiments may be described and claimed.
