Abstract:
The present disclosure is directed to a unified device interface for a multi-bus system. In at least one embodiment, a system may comprise more than one data bus. Each data bus may be to convey data between an operating system (OS) and at least one device in the system, wherein a plurality of driver instances may facilitate interaction between the OS and a device via one or more of the data buses. In one embodiment, a main driver instance may be determined from the plurality of driver instances to present the device to the OS and coordinate operation of other driver instances. The other driver instances may map addresses in the memory of processing entities corresponding to each of the data buses and report these mappings to the main driver instance. Alternatively, a supervisory driver may be loaded to present the device and to control operation of the driver instances.
Abstract:
Generally, this disclosure provides devices, methods, and computer readable media for packet processing with reduced latency. The device may include a data queue to store data descriptors associated with data packets, the data packets to be transferred between a network and a driver circuit. The device may also include an interrupt generation circuit to generate an interrupt to the driver circuit. The interrupt may be generated in response to a combination of an expiration of a delay timer and a non-empty condition of the data queue. The device may further include an interrupt delay register to enable the driver circuit to reset the delay timer, the reset postponing the interrupt generation.
Abstract:
Examples are disclosed for access to a storage device maintained at a server. In some examples, a network input/output device coupled to the server may allocate, in a memory of the server, a buffer, a doorbell, and a queue pair accessible to a client remote to the server. For these examples, the network input/output device may assign an Non-Volatile Memory Express (NVMe) namespace context to the client. For these examples, indications of the allocated buffer, doorbell, queue pair, and namespace context may be transmitted to the client. Other examples are described and claimed.
Abstract:
Various embodiments are generally directed to techniques for cooperation between a higher function core and a lower power core to minimize the effects of interrupts on a current flow of execution of instructions. An apparatus may include a lower power core comprising a first instruction pipeline, the lower power core to stop a first flow of execution in the first instruction pipeline and execute instructions of a handler routine in the first instruction pipeline to perform a first task of handling an interrupt; and a higher function core comprising a second instruction pipeline, the higher function core to, following the performance of the first task, schedule execution of instructions of a second task of handling the interrupt in the second instruction pipeline to follow a second flow of execution in the second instruction pipeline, the first task more time-sensitive than the second task. Other embodiments are described and claimed.

Abstract:
Embodiments may be generally directed to techniques to receive rate meter information indicating an occurrence of a rate meter event, the rate meter event determined by a rate meter associated with a network element in a software defined network (SDN) environment. determine a requirement for a service provided by the network element is not met based on the rate meter event detected by the rate meter. Embodiments may also include techniques to determine a corrective action based on the requirement not met, the corrective action to cause the requirement to be met for the service provided by the network element in the SDN environment and cause the correct action to be performed for the network element.
