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: Generally, this disclosure provides systems, methods and computer readable media for management of sockets and device queues for reduced latency packet processing. The method may include maintaining a unique-list comprising entries identifying device queues and an associated unique socket for each of the device queues, the unique socket selected from a plurality of sockets configured to receive packets; busy-polling the device queues on the unique-list; receiving a packet from one of the plurality of sockets; and updating the unique-list in response to detecting that the received packet was provided by an interrupt processing module. The updating may include identifying a device queue associated with the received packet; identifying a socket associated with the received packet; and if the identified device queue is not on one of the entries on the unique-list, creating a new entry on the unique-list, the new entry comprising the identified device queue and the identified socket.

Abstract: Technologies for control plane separation at a network interface controller (NIC) of a compute device configured to transmit, by a resource of the compute device, commands to a physical function managed by a network interface controller (NIC) of the compute device. The NIC is further to establish a data plane separate from a control plane, wherein the control plane comprises one of the trusted control path and the untrusted control path. Additionally, the resource is configured to transmit the commands via one of the trusted control path or the untrusted control path based on a trust level associated with the physical function. Other embodiments are described herein.

Abstract: Examples are disclosed for forwarding or receiving data segments associated with a large data packets. In some examples, a large data packet may be segmented into a number of data segments having separate headers that include identifiers to associate the data segments with the large data packet. The data segments with separate headers may then be forwarded from a network node via a communication channel. In other examples, the data segments with separate headers may be received at another network node and then recombined to form the large data packet at the other network node. Other examples are described and claimed.

Abstract: Examples are disclosed for use of vendor defined messages to execute a command to access a storage device maintained at a server. In some examples, a network input/output device coupled to the server may receive the command from a client remote to the server for the client to access the storage device. For these examples, elements or components of the network input/output device may be capable of forwarding the command either directly to a Non-Volatile Memory Express (NVMe) controller that controls the storage device or to a manageability module coupled between the network input/out device and the NVMe controller. Vendor specific information may be forwarded with the command and used by either the NVMe controller or the manageability module to facilitate execution of the command. 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: Methods and apparatus are disclosed for virtualizable, forward-compatible hardware-software interfaces. Embodiments may be used in a driver whether it is a physical driver or a virtual driver. Commands are queued from the driver and fetched to the device. An actions table is accessed to determine if drivers are permitted to perform commands. Events are queued for the drivers responsive to commands. If drivers are not permitted to perform a command, device firmware may forward the command to a privileged driver to perform the required command. If a driver is only permitted to perform a command with assistance the command is forwarded for corrections and execution. If a command is to be dropped, a completion event may be queued as if the command had executed. Drivers may have no indication of which actions were taken. The actions table may be changed for hardware/software modifications or dynamically according to configuration changes.
