摘要:
Techniques are described herein that can be used to control which packets or other data are able to be processed or otherwise utilize logic of a computing device. For example, a signature may be associated with a packet or other data received from a network. The signature and the packet or other data may be transferred to the computing device. Prior to the computing device deciding whether to allow logic such as hardware or software to use, process, or act using the packet or other data, the computing device may inspect the signature to determine if such signature permits such packet or other data to be used, processed, or acted upon.

In one embodiment, a method is provided. The method of this embodiment provides storing a packet header at a set of at least one page of memory allocated to storing packet headers, and storing the packet header and a packet payload at a location not in the set of at least one page of memory allocated to storing packet headers.
摘要:
A dual interface coherent and non-coherent network interface controller architecture is generally presented. In this regard, a network interface controller is introduced including a non-coherent bus interface to communicatively couple with devices of a system through a non-coherent protocol, the non-coherent bus interface to facilitate discovery of the network interface controller by an operating system, a coherent bus interface to communicatively couple with devices of the system through a coherent protocol, and a coherency engine to perform coherent transactions over the coherent interface including to snoop for writes on system memory. Other embodiments are also disclosed and claimed.

According to some embodiments, it may be determined, at a first processing element of a device with a plurality of processing elements, that first data is to be transmitted in association with a first network connection. A first entry associated with the first data may then be stored into a first of a plurality of transmit queues. It may subsequently be determined, at a second processing element of the device, that second data is to be transmitted in association with the first network connection. A second entry associated with the second data may then be stored into a second of the plurality of transmit queues.

In one embodiment, a data movement module (DMM) may receive a command to copy data from a source buffer to a destination buffer. One or more cache lines corresponding to addresses of the source buffer and the destination buffer may be invalidated. Also, an entry may be added to a queue to indicate that the command to copy is completion pending.
摘要:
In one embodiment, it may be determined whether a processor is going to access a packet payload that is stored in a source buffer. If the processor is not going to access the packet payload, a data movement module (DMM) may move the packet payload from the source buffer to a destination buffer.

Provided are a method, system, and program for managing transmit throughput for a network controller. In one embodiment, transmit requests from an application may be posted by the device driver to the network controller of the network adapter in a pipeline of transmit requests without waiting for an acknowledgment of the transfer of the accompanying transmit data to the network controller. In another aspect, a device driver monitors the available buffer space of a network controller buffer to ensure that the network controller has sufficient available buffer space before posting the next transmit request to the network controller. In accordance with yet another aspect, the device driver can copy transmit data from an application buffer to a driver buffer if the size of the transmit data of a particular transmit request is below a programmable threshold. If so, the device driver can notify the application to permit the application buffer to be released.

摘要:
In one embodiment, a method is provided. The method of this embodiment provides performing packet processing on one or more packets, and substantially simultaneously with said performing packet processing, using a data movement module to place one or more payloads corresponding to the one or more packets into a read buffer.
