[0002] With the development of the Internet, there are more and more types of network devices on electronic devices. The same electronic device is often equipped with cellular networks, Universal Serial Bus (USB), Wi-Fi, Ethernet and other network devices at the same time. Therefore, Internet Protocol Accelerator (IPA) has emerged. The data of all network devices on the device are routed and forwarded by this IPA. In the current solution of receiving data through IPA, the processor will create an additional thread to process the received data and trigger the network card to read the data. This solution consumes a lot of processor resources. Summary of the invention

[0003] A data processing method, device, electronic device and storage medium can reduce the resource consumption of a processor.

[0005] In a possible implementation, the received data is diverted by triggering a virtual network card through an interrupt, and the process of obtaining the diverted received data includes: acquiring the received data and the source identifier and network identifier corresponding to the received data; obtaining the corresponding device identifier based on the source identifier and the network identifier; configuring the received data based on the device identifier to obtain the diverted received data.

[0006] In a possible implementation, the electronic device further includes a plurality of network cards of different types, and the data processing method further includes: acquiring transmission data from any network card; and sending the transmission data to the IPA.

[0007] In a possible implementation, obtaining the received data from the IPA includes: obtaining the received data from the IPA, and forming the received data in a socket buffer skb format based on the received data.

[0008] In a second aspect, an application processor is provided for an electronic device, the electronic device including an Internet Protocol accelerator IPA, the IPA being used to route and forward data, the application processor including: a first acquisition module, used to acquire received data from the IPA; a diversion module, used to divert the received data by triggering a virtual network card through an interrupt to obtain the diverted received data; and a second acquisition module, used to acquire the diverted received data through a network subsystem in the application processor.

[0010] In a possible implementation, the electronic device further includes a plurality of network cards of different types, and the application processor further includes: a third acquisition module, configured to acquire transmission data from any network card; and a transmission module, configured to send the transmission data to the IPA.

[0021] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0022] For the received data from IPA, the received data in the socket buffer (skb) format can be obtained through an interrupt trigger, and the received data can be diverted and cached through an independent receive task (recv task) thread, and then the corresponding network interface card (NIC) driver is triggered to read the cached received data, and then sent to the network subsystem network subsystem in the application processor, that is, data is received from IPA through different network cards. However, since it is necessary to create an independent recv task thread to process the data, the microprocessor without interlocked piped stages (mips) in the central processing unit (CPU) is consumed more, that is, the CPU resources are consumed more, and the round-trip time (RTT) is higher; in addition, since the recv task needs to have a higher priority, this will cause the soft interrupt to be unable to be scheduled in time when the soft interrupt is triggered, which may cause the data from IPA to be unable to be transmitted in time.

[0023] The present application embodiment provides a data processing method for an electronic device, such as Figure 1 and Figure 2As shown, the electronic device includes an application processor (AP), a plurality of different types of network cards and an Internet Protocol Accelerator (IPA), and the IPA is used to route and forward data. The execution subject of the data processing method in the embodiment of the present application is the AP.

[0024] 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 expansion bus standard (peripheral component interconnect express, pcie) endpoint, an Ethernet endpoint, and a communication processor (Communication Processor, CP) endpoint. The above endpoints are used to realize the transmission of different network data. For example, the USB endpoint is used to transmit USB data, corresponding to the USB network card, the CP endpoint is used to transmit cellular data, corresponding to the modem network card, the Wi-Fi endpoint is used to transmit Wi-Fi data, corresponding to the Wi-Fi network card, the Ethernet endpoint is used to transmit Ethernet data, corresponding to the Ethernet network card, and in addition, the pcie endpoint can also be used to transmit Ethernet data, that is, corresponding to the Ethernet network card. It should be noted that the above network cards and endpoints are only examples. As needed, the electronic device can include more types of other endpoints and network cards, and some endpoints and network cards can also be reduced. The embodiment of the present application does not limit the specific number and type of network cards and the number and type of endpoints in the IPA.

[0025] It should also be noted that Figure 2 In the figure, the box corresponding to AP is used to represent the content related to AP, such as the physical devices and virtual modules controlled by AP. In other words, Figure 2 The box corresponding to AP does not represent the content contained in AP, but represents the content related to AP. IPA also includes AP output endpoint and AP input endpoint. AP output endpoint is used to output data of IPA to AP, and AP input endpoint is used to input data from AP to IPA. AP output endpoint can transmit data through AP receiving channels 1 to N, and AP input endpoint can transmit data through AP sending channels 1 to N.

[0026] The application processor includes a network subsystem, which specifically belongs to a virtual module corresponding to the TCP / IP protocol layer and is used to execute related processing of the TCP / IP protocol layer in the network.

[0027] IPA also includes a router / bridge module, which can be used to implement data routing forwarding, bridging transmission, etc. between different endpoints. Through configuration, the acceleration function can be achieved.

[0028] For example, when an electronic device receives data through a cellular network, the data is first input through the CP endpoint of the IPA and output to the AP through the IPA, so that the electronic device can obtain the data received through the cellular network. When the electronic device sends data through the cellular network, the AP sends the data to the IPA, and the IPA sends the data through the CP endpoint. In addition, the electronic device can also transmit data through other communication methods, such as transmitting data through the USB endpoint, Wi-Fi endpoint, PCIE endpoint or Ethernet endpoint in the IPA through the corresponding communication method. In addition, other forms of data transmission can also be achieved by configuring the routing / bridging module in the IPA. For example, the IPA sends the cellular network data received through the CP endpoint directly through the Wi-Fi endpoint to achieve the function of the Wi-Fi hotspot.

[0029] like Figure 3 As shown, the data processing method in the embodiment of the present application includes:

[0030] Step 101: Acquire received data from the IPA, that is, acquire received data through the AP output endpoint on the IPA;

[0031] Step 102: Trigger the virtual dummy network card through an interrupt to divert the received data, and obtain the diverted received data;

[0032] In an embodiment of the present application, a virtual network card is specially created. When the IPA receives data, the received data is cached, and the fill task thread created by the IPA driver fills the received data to form received data in skb format, and interrupts the new application programming interface (NAPI) of the virtual network card to read the data, and then the received data is diverted. Diversion refers to distinguishing which specific network card the received data corresponds to, that is, the received data corresponding to all network cards are uniformly received and managed by the virtual network card.

[0033] Step 103: Obtain the diverted received data through the network subsystem in the application processor.

[0034] The data processing method in the embodiment of the present application triggers the virtual network card to divert the received data through an interrupt. Since the interrupt operation is required in the process of data transmission, the interrupt process can be reused to realize the diversion of the received data, thereby eliminating the need to divert the data through an independent thread. Compared with the method of diverting data through an independent thread, the resource consumption of the processor is reduced, and the RTT is reduced. Moreover, since all data are uniformly processed through the interrupt of the virtual network card, compared with the need to interrupt the data of different network cards separately, there is no need to interrupt each corresponding to different network cards, thereby reducing the number of interruptions.

[0035] In addition, since the received data of all network cards are uniformly processed by the virtual network card, the same operations in the received data can be completed centrally, and some special processing required by different network cards can also be executed separately after the virtual network card completes the processing of the received data, and then sent to the network subsystem of the application processor. For example, in a possible implementation, 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, it can be directly sent to the network subsystem of the application processor after being diverted by the virtual network card, and for the received data corresponding to the Wi-Fi network card, after being diverted by the virtual network card, it can also be given to the Wi-Fi network card through a notification chain to perform some special processing on the data, and then sent to the network subsystem of the application processor after processing. That is, the embodiment of the present application does not limit the specific process of the above-mentioned step 103 and obtaining the diverted received data through the network subsystem in the application processor. It can be sent directly to the network subsystem or sent to the network subsystem after other processing.

[0036] In addition, IPA can also have a hardware offload function, which can put the functions originally executed by AP on the hardware IPA.

[0037] In a possible implementation, Figure 4 As shown, the above step 102, triggering the virtual network card to divert the received data by interruption, and the process of obtaining the diverted received data includes:

[0038] Step 1021, obtaining received data and a source identifier (source, src) id and a network identifier net id corresponding to the received data;

[0039] After the interrupt triggers the NAPI of the virtual network card to read data, step 1021 can be entered. src id is used to mark the network type, or the network card type, for example, 0x1 represents a USB network card, 0x2 represents a Wi-Fi network card, net id is used to mark the network card serial number under the same network type or network card type, for example, the above-mentioned modem network card actually includes multiple modem network cards from modem network card 0 to modem network card n, 0 represents network card serial number 0, n represents network card serial number n, net id is used to mark a specific network card, for example, Modem nic0 represents modem network card 0, Modem nicn represents modem network card n, USB nic represents USB network card, Veth nic0 represents Ethernet network card 0, Veth nicen represents Ethernet network card n;

[0040] Step 1022, obtaining a corresponding device identifier (netdevice, netdev) according to the source identifier src id and the network identifier net id;

[0041] Table 1

[0042]

[0043]

[0044] Among them, Table 1 is a mapping table of source identifier src id, network identifier net id and device identifier netdev. Based on this mapping table, the corresponding netdev can be obtained according to the matching of src id and net id, and netdev can determine the specific network card corresponding to the received data. The mapping table can be an array structure, without traversal query or calculation of key value.

[0045] Step 1023: configure the received data according to the device identifier netdev to obtain the received data after diversion.

[0046] The received data is configured, that is, the corresponding netdev is set in the received data, even if the received data carries specific netdev, and then the interface can be called to send the received data to the network subsystem of the application processor, so that the network subsystem can determine which specific network card the received data corresponds to according to netdev.

[0047] In a possible implementation, the data processing method further includes: obtaining the transmission data from any network card; sending the transmission data to IPA. For the data from AP that needs to be sent by IPA, each network card driver calls the transmission interface provided by the IPA driver to send it, and after the sending is completed, the cache release action is uniformly released by the release task free task thread created by the IPA driver. That is to say, in the embodiment of the present application, for the transmission data that needs to be sent using IPA, it is still sent through each network card.

[0048] In a possible implementation, obtaining the received data from the IPA in step 101 includes: obtaining the received data from the IPA, and forming the received data in the socket cache skb format based on the received data, that is, filling the received data through the fill task thread created by the IPA driver to form the received data in the skb format.

[0049] like Figure 5 As shown, an embodiment of the present application also provides an application processor for an electronic device, the electronic device includes an Internet Protocol accelerator IPA, the IPA is used to route and forward data, and the application processor includes: a first acquisition module 10, used to obtain received data from the IPA; a diversion module 20, used to divert the received data by triggering a virtual network card through an interrupt to obtain the diverted received data; a second acquisition module 30, used to obtain the diverted received data through a network subsystem in the application processor.

[0051] It should be understood that the above Figure 5The division of the modules of the application processor shown is only a division of logical functions.

And these modules can all be implemented in the form of software calling through processing elements; they can also be all implemented in the form of hardware; some modules can also be implemented in the form of software calling through processing elements, and some modules can be implemented in the form of hardware.

In addition, it can also be stored in the memory of the application processor in the form of a program, and called and executed by a certain processing element of the application processor. The implementation of other modules is similar. In addition, all or part of these modules can be integrated together, or they can be implemented independently. The processing element described here can be an integrated circuit with signal processing capabilities. In the implementation process, each step of the above method or each module above can be completed by an integrated logic circuit of hardware in the processor element or instructions in the form of software.

For another example, when a certain module above is implemented in the form of a processing element scheduler, the processing element can be a general-purpose processor, such as a central processing unit (CPU) or other processor that can call a program. For another example, these modules can be integrated together and implemented in the form of a system-on-a-chip (SOC).

[0053] In a possible implementation, the diversion module 20 is specifically used to: obtain received data and a source identifier and a network identifier corresponding to the received data; obtain a corresponding device identifier based on the source identifier and the network identifier; configure the received data based on the device identifier to obtain the diverted received data.
