[0026] Example 1

[0027] Figure 1 A flowchart of a data transmission method under virtualization management is provided for the first embodiment of the present invention. This embodiment is applicable to cross-domain interactive data. The method is applied to the same system-on-chip (SOC), which includes a first platform domain and a second platform domain. It can be executed by a data transmission device under virtualization management. The data transmission device under virtualization management can be implemented in the form of hardware and / or software, and the data transmission device under virtualization management can be configured in an electronic device.

[0028] like Figure 1 As shown, the method includes:

[0029] S110. Receive business data from the user space through the first platform domain, determine the target data packet of the business data in the target format in combination with the first driver of the first virtual Ethernet in the kernel space, write the target data packet into the designated memory area, and send a notification message to the second platform domain.

[0030] In this embodiment, the first platform domain can be understood as an independent CPU unit, such as an AP domain or a CP domain. The user space can be understood as the running space of the user program. The kernel space can be understood as the running space of the Linux kernel, such as kernalspace. The first virtual Ethernet can be understood as a virtual network that works according to the Ethernet principle at the data link layer through software methods in the real Internet, and the first virtual Ethernet runs in the first platform domain. Business data can be understood as data that needs to be processed, such as vehicle signal data, AVM business control data, navigation screen projection to the instrument screen image data, etc. The target format can be understood as a format for writing, which can preferably be a raw format. The first driver can be understood as a program set in the first platform domain for realizing the business functions of the virtual network card, such as: turning the network card on and off, transmitting network frame data, receiving network frame data, etc.

[0031] In this embodiment, the second platform domain can be understood as an independent CPU unit, such as an AP domain or a CP domain. The target data packet can be understood as a data packet generated after processing service data and receivable by the second platform domain. The storage information can be understood as information including the address of the target data packet. The notification message can be understood as a message sent to the second platform domain to notify the second platform domain of the storage information of the target data packet.

[0032] Specifically, the first platform domain can receive service data sent from the user space. After transmitting the service data to the kernel space, the service data can be converted into a form that can be received by the virtual Ethernet. The service data in the converted form can then be encapsulated in combination with the first driver of the first virtual Ethernet in the kernel space. The encapsulated service data is re-encapsulated according to the target format to form a target data packet. The target data packet can be written into the designated memory area by dividing the shared memory area of ​​the memory hardware. The first platform domain can send a notification message to the second platform domain through the hardware channel. The memory hardware can be LPDDR and the hardware channel can be Mailbox. The present invention only uses this as an example and does not specifically limit the memory hardware and hardware channel.

[0033] S120: Receive a notification message through the second platform domain, and obtain service data in the user space of the second platform domain based on the notification message and the second driver of the second virtual Ethernet in the kernel space of the second platform domain.

[0034] In this embodiment, the second virtual Ethernet can be understood as a virtual network operating according to Ethernet principles implemented at the data link layer using software methods in the real Internet and running in the second platform domain. The second driver can be understood as a program configured in the second platform domain to implement the service functions of the virtual network card.

[0035] Specifically, the notification message sent by the first platform domain can be received through the hardware channel of the second platform domain. The second platform domain reads the target data packet from the memory hardware according to the notification message, and parses the target data packet through the second driver of the second virtual Ethernet in the kernel space of the second platform domain. The parsed target data packet is then converted into a form that can be received by the user space, that is, converted into a business data form, and the business data is sent to the user space of the second platform domain to obtain the business data in the user space of the second platform domain.

[0036] The technical solution of an embodiment of the present invention is applied to the same system-on-chip (SOC), which includes a first platform domain and a second platform domain. The method includes: receiving business data from the user space through the first platform domain, combining with a first driver of a first virtual Ethernet in the kernel space, determining a target data packet of the business data in a target format, writing the target data packet to a designated memory area, and sending a notification message to the second platform domain; receiving a notification message through the second platform domain, and obtaining business data in the user space of the second platform domain based on the notification message and combining with a second driver of a second virtual Ethernet in the kernel space of the second platform domain. Through the virtual Ethernet, support for standard network socket communication-related APIs and support for multiple network protocol stacks between different platform domains is achieved, thus achieving a standard, efficient, simple, and universal communication method for different platform domains.

[0037] Example 2

[0038] Figure 2 This is a flowchart of a data transmission method under virtualization management provided by the second embodiment of the present invention. This embodiment is a further refinement based on the above embodiment. Figure 2 As shown, the method includes:

[0039] S201: Receive service data from a user space through a first platform domain, and convert the service data into a first data stream through a set network protocol stack.

[0040] In this embodiment, the first data stream can be understood as a set of ordered byte data sequences with a start point and an end point in the first platform domain. The network protocol stack can be understood as a protocol stack set for completing communication.

[0041] The network protocol stack is configured with at least one standard network protocol, such as socket API, HTTP, TCP / UDP, SOME / IP and other network protocols.

[0042] Specifically, the first platform domain can receive business data in the user space, send the business data to the kernel space, and convert the business data in the kernel space through the set network protocol stack to form a first data stream under the corresponding network protocol.

[0043] S202: Encapsulate the first data stream into first network frame data under a specified protocol.

[0044] In this embodiment, the designated protocol can be understood as the protocol configured in the first platform domain. The first network frame data can be understood as the data transmitted in the first platform domain in the Ethernet.

[0045] Specifically, the first platform domain may encapsulate the first data stream according to a specified protocol to form network frame data corresponding to the first data stream.

[0046] Exemplarily, the designated protocol may be a TCP / IP protocol stack, and the first data stream is encapsulated by the TCP / IP protocol stack into TCP / IP protocol network frame data.

[0047] S203: Drive the first virtual network card through the first driver to encapsulate the first network frame data to obtain an intermediate data packet.

[0048] In this embodiment, the first virtual network card can be understood as a virtual network card in the first platform domain that simulates a network environment through software and simulates the function of a network adapter. The intermediate data packet can be understood as a data packet encapsulated in a memory format.

[0049] Specifically, after the first network frame data is formed, the first platform domain may drive the first virtual network card through the first driver program to encapsulate the first data frame data according to a set format to obtain an intermediate data packet.

[0050] Exemplarily, after the TCP / IP protocol network frame data is formed, the first driver drives the first virtual network card to encapsulate the first network frame data into an intermediate data packet in the RPMSG format.

[0051] S204: Encapsulate the intermediate data packet according to the target format to obtain the target data packet.

[0052] Specifically, after the intermediate data packet is formed, the first platform domain may encapsulate the intermediate data packet according to the target format to obtain a target data packet in the target format.

[0053] Exemplarily, the first platform domain may encapsulate the intermediate data packet in the RPMSG format to form a target data packet in the raw format.

[0054] S205: Writing the target data packet into the designated memory area through a preset bus protocol.

[0055] In this embodiment, the preset bus protocol can be understood as a bus protocol under a preset hardware mechanism. The storage address can be understood as a location where the target data packet is stored.

[0056] Specifically, the first platform domain may transmit the target data packet to the designated memory area through a preset bus protocol.

[0057] S206: After writing is completed, a notification message is sent to the second platform domain.

[0058] Specifically, after the first platform domain completes writing the target data packet, the first platform domain may automatically generate a notification message and send the notification message to the second platform domain according to a set transmission method.

[0059] For example, the first platform domain and the second platform domain can each be interconnected via Mailbox hardware. The first platform domain generates a Mailbox message based on stored information and sends the Mailbox message to the second platform domain. The term "Mailbox" refers to the ability of two different platform domains to exchange messages via a Mailbox hardware channel. A Mailbox consists of two FIFOs, status registers, and control registers, and is a bidirectional message channel.

[0060] S207: Determine a designated memory area according to the notification message.

[0061] Specifically, the second platform domain may receive the notification message sent by the first platform domain through a hardware channel. After receiving the notification message, the second platform domain may determine a designated memory area according to a pre-configured configuration.

[0062] Exemplarily, the second platform domain is connected to the LPDDR hardware via AXI, and a designated memory area on the LPDDR is determined by storing information.

[0063] S208. Read the target data packet from the designated memory area.

[0064] Specifically, the second platform domain may read the target data packet from the designated memory area through a set bus protocol.

[0065] S209: Determine a second data stream under the target protocol according to the target data packet and the second driver.

[0066] In this embodiment, the second data stream can be understood as a set of ordered byte data sequences with a start point and an end point in the second platform domain. The target protocol can be understood as the communication protocol configured in the second platform domain.

[0067] Specifically, the second platform domain can parse the target data packet through the second driver of the second virtual Ethernet in the kernel space, convert the parsed target data packet to form a second data stream under the target protocol. If the target protocol can be the TCP / IP protocol, the second data stream corresponds to the data stream under the TCP / IP protocol.

[0068] Furthermore, according to the target data packet and the second driver, the step of determining the second data flow under the target protocol may be:

[0069] The second virtual network card is driven by the second driver to parse the target data packet to determine the second network frame data; and the second network frame data is parsed to determine the second data stream.

[0070] In this embodiment, the second virtual network card can be understood as a virtual network card in the second platform domain that simulates a network environment and a network adapter function through software simulation. The second network frame data can be understood as data transmitted in the Ethernet in the second platform domain.

[0071] Specifically, the second platform domain may drive the second virtual network card through the second driver to parse the target data packet to determine the second network frame data, and then the second platform domain may parse the second network frame data to determine the second data flow.

[0072] Exemplarily, the second platform domain can first parse the target data table in the raw format to form a target data table in the RPMSG format, and drive the second virtual network card through the second driver to parse the target data packet in the RPMSG format to determine the second network frame data. The second platform domain then parses the second network frame data to determine the second data stream under the TCP / IP protocol.

[0073] S210: Parse the second data stream through a set network protocol stack to obtain service data in the user space.

[0074] Specifically, the second data stream is parsed through a set network protocol stack to obtain business data, and the business data is sent to the user space, and the business data is obtained in the user space.

[0075] The technical solution of the embodiment of the present invention is to encapsulate business data through the network protocol stack of the first platform domain to form a data stream, and encapsulate the data stream into network frame data under the specified protocol. The virtual Ethernet driver drives the virtual network card to encapsulate the network frame data to obtain an intermediate data packet, and encapsulates it according to the corresponding storage format and stores it in the shared memory. A notification message is sent to the second platform domain through the hardware channel. The target data packet is carried out by the second platform domain according to the notification message, and the target data packet is parsed. The target data packet is driven by the virtual Ethernet driver to parse the virtual network card to obtain network frame data, and then the network frame data is converted into business data through the network protocol stack and sent to the user space of the second platform domain. It realizes support for standard network socket communication-related APIs between different platform domains and supports multiple network protocol stacks; it realizes standard, efficient, simple and universal communication methods for different platform domains.

[0076] For example, to facilitate understanding of the present invention, a vehicle data service is taken as an example, the first platform domain is the AP domain, and the second platform domain is the CP domain. The AP domain can also be used as the second platform domain, and the CP domain can also be used as the first platform domain. An exemplary description is given in the form of software architecture.

It also receives Mailbox messages from the CP domain, retrieves raw data from the designated memory area in the AP domain shared memory, and passes it to the AP domain virtual Ethernet driver.

[0081] 5. Mailbox & Shared Memory: This refers to the underlying software implementation of AP domain communication. The Mailbox is primarily responsible for sending and receiving events, while the Shared Memory is shared between the AP domain and the CP domain, which handles large amounts of data. The AP Mailbox notifies the CP domain Mailbox of messages and also receives messages from the CP domain Mailbox.
