Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
For received data from IPA, the received data in a socket buffer (skb) format may be obtained through interrupt triggering, the received data is shunted and buffered through an independent receive task (rev task) thread, then a corresponding Network Card (NIC) is triggered to drive and read the buffered received data, and then the buffered received data is sent to a Network subsystem in an application processor, that is, the data is received from IPA through different Network cards. However, since an independent recv task thread needs to be created to process data, the consumption of microprocessors (mips) without internal interlocking pipeline in a Central Processing Unit (CPU) is high, that is, the resource consumption of the CPU is high, and the Round-Trip delay (RTT) is high; in addition, the recv task is required to have a higher priority, which may cause the soft interrupt not to be scheduled in time when the soft interrupt is triggered, thereby possibly causing data from the IPA not to be transmitted in time.
An embodiment of the present Application provides a data processing method, which is used for an electronic device, as shown in fig. 1 and fig. 2, where the electronic device includes an Application Processor (AP), a plurality of different types of network cards, and an internet protocol accelerator IPA (ip a) for routing and forwarding data. In the embodiment of the present application, an execution subject of the data processing method is an AP.
For example, the network card may include a Wi-Fi network card, a USB network card, a Modem network card, and an Ethernet network card, the IPA may include a USB endpoint, a Wi-Fi endpoint, a high-speed serial computer extended bus standard (pci) endpoint, an Ethernet endpoint, and a Communication Processor (CP) endpoint, where the endpoints are used to implement transmission of different network data, for example, the USB endpoint is used to transmit USB data, the USB endpoint corresponds to the USB network card, the CP endpoint is used to transmit cellular data, the Wi-Fi endpoint is used to transmit Wi-Fi data, the Wi-Fi network card corresponds to the Wi-Fi network card, and the Ethernet endpoint is used to transmit Ethernet data, the Ethernet network card corresponds to the Ethernet network card, and the pci endpoint may also be used to transmit Ethernet data, that is, the Ethernet network card corresponds to the Ethernet network card. It should be noted that the above network cards and the endpoints are only examples, and the electronic device may include more types of other endpoints and network cards or may reduce some of the endpoints and network cards as needed.
It should be noted that, in fig. 2, the blocks corresponding to the AP are used to indicate contents related to the AP, and include, for example, a physical device and a virtual module controlled by the AP, that is, the blocks corresponding to the AP in fig. 2 do not indicate contents included in the AP, but indicate contents related to the AP. The IPA further includes an AP output endpoint for outputting data of the IPA to the AP and an AP input endpoint for inputting data from the AP to the IPA, wherein the AP output endpoint may transmit data through the reception channels 1 to N of the AP and the AP input endpoint may transmit data through the transmission channels 1 to N of the AP.
The application processor comprises a network subsystem, wherein the network subsystem specifically belongs to a virtual module corresponding to a TCP/IP protocol layer and is used for executing relevant processing of the TCP/IP protocol layer in the network.
The IPA further includes a route/bridge module, which may be configured to implement data routing forwarding, bridge transmission, and the like between different endpoints, and may implement an acceleration function through configuration.
For example, when an electronic device receives data over a cellular network, data is first input through a CP endpoint of an IPA and output through the IPA to an AP so that the electronic device can acquire the data received over the cellular network, and when the electronic device sends data over the cellular network, the AP sends the data to the IPA, which sends the data by the CP endpoint. In addition, the electronic device may also transmit data through other communication manners, for example, transmit data through a USB endpoint in IPA, a Wi-Fi endpoint, a pcie endpoint, or an ethernet endpoint through a corresponding communication manner. In addition, other forms of data transmission can also be achieved by utilizing the configuration of the routing/bridging module in the IPA, for example, cellular network data received by the IPA via the CP endpoint is directly sent out via the Wi-Fi endpoint, so as to realize the function of the Wi-Fi hotspot.

In addition, since the received data of all the network cards are processed by the virtual network cards in a unified manner, the same operations in the received data can be collectively completed, and some special processing required by different network cards can be performed, or the received data can be independently executed after the processing of the received data by the virtual network cards is completed, and then the processed data is sent to the network subsystem of the application processor, for example, in a possible implementation manner, if the received data is data corresponding to a USB network card, data corresponding to a modem network card or data corresponding to an ethernet network card, the data can be distributed by the virtual network cards and then directly sent to the network subsystem of the application processor, and for the received data corresponding to a Wi-Fi network card, some special processing can be performed on the data by giving a Wi-Fi network card in a manner of a notification chain after the data is distributed by the virtual network cards, after the processing, the data is sent to the network subsystem of the application processor, that is, in the embodiment of the present application, the specific process of obtaining the shunted received data by the network subsystem in the application processor in step 103 is not limited, and the data may be sent to the network subsystem directly or may be sent to the network subsystem after other processing.
In addition, the IPA may also have a hardware offload function, which may place functions that would otherwise be performed by the AP on the hardware IPA for completion,
in a possible implementation manner, as shown in fig. 4, in the step 102, the process of triggering the virtual network card to split the received data through interruption to obtain the split received data includes:
after the interruption triggers the NAPI of the virtual network card to read the data, step 1021 may be entered. src id is used to mark a network type or a network card type, for example, 0x1 represents a USB network card, 0x2 represents a Wi-Fi network card, and net id is used to mark a network card serial number under the same network type or network card type, for example, the above Modem network card actually includes a plurality of Modem network cards from Modem network card 0 to Modem network card n, 0 represents a network card serial number 0, n represents a network card serial number n, net id is used to mark a specific network card, for example, Modem nic0 represents a Modem network card 0, Modem nic represents a Modem network card n, USB nic represents a USB network card, Veth nic0 represents an ethernet network card 0, and Veth nic represents an ethernet network card n;
