Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to a method, apparatus, and storage medium for restoring abnormal states of inter-core communication pathways. Background Technology

[0002] Inside a System on Chip (SoC), when the host user thread crashes but the slave is running normally, the IPC interface can only reconnect after the slave restarts. However, if the host user thread restarts but the slave is still alive, the communication path cannot be established. A special mechanism is needed to restart both the host user thread and the slave to restore normal operation, which takes a long time. Summary of the Invention

[0003] The purpose of this invention is to provide a method, apparatus, and storage medium for restoring abnormal states of inter-core communication pathways. The specific technical solution adopted is as follows:

[0004] In a first aspect, embodiments of the present invention provide a method for restoring the abnormal state of inter-core communication pathways, the method comprising:

[0005] Obtain the operating status of the master and slave devices;

[0006] When the host machine is in an abnormal operating state and the slave machine is in a normal operating state, determine the type of inter-core communication message;

[0007] If the type of the inter-core communication message is a preset type, determine whether the host terminal has no alarm reset;

[0008] If the host terminal does not reset the alarm, a communication path is established between the host terminal and the slave terminal based on the initial handshake process.

[0009] Secondly, embodiments of the present invention provide a device for restoring abnormal states of inter-core communication pathways, the device comprising:

[0010] The acquisition module is used to acquire the operating status of the host and slave devices;

[0011] The first determining module is used to determine the type of inter-core communication message when the operating state of the host is abnormal and the operating state of the slave is normal.

[0012] The second determining module is used to determine whether the host terminal has no alarm reset if the type of the inter-core communication message is a preset type.

[0013] A module is established to establish a communication path between the host and the slave device based on the initial handshake process if the host device does not have an alarm reset.

[0014] Thirdly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the method described in the first aspect.

[0015] Fourthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the method described in the first aspect.

[0016] This invention offers the following advantages: After acquiring the operating status of the host and slave terminals, if the host terminal's operating status is abnormal and the slave terminal's operating status is normal, the type of inter-core communication message is determined. Thus, in the case of a host terminal disconnection while the slave terminal operates normally, it is determined whether the type of the inter-core communication message indicates that the channel is open. If the type of the inter-core communication message indicates that the channel is open, it is determined whether the host terminal has no alarm reset. If the host terminal has no alarm reset, a communication path between the host and slave terminals is established based on the initial handshake process. Therefore, when the host terminal experiences an anomaly and restarts itself without notifying the slave terminal, by determining the type of the inter-core communication message, if the type of the inter-core communication message indicates that the channel is open, the path between the host and slave terminals is re-established, and the transmission of service data is restored, ensuring that communication can be restored as quickly as possible after a single-end abnormal reset.

[0024] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a method for restoring an abnormal state of an inter-nuclear communication pathway according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments may be combined from any suitable form.

[0025] In the description of the embodiments of the present invention, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present invention, "multiple" means two or more.

[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] In some embodiments, Inter-Processor Communication (IPC) is a module that manages shared memory data formatting and simplifies application data transfer between the SoC and the processor, based on interrupt notifications (IPI, GPIO, or Mailbox IRQ mode) or by having the logic control unit (Mailbox) of multi-core communication carry data and notify via interrupts. Overall, the core is the operation of shared memory by the application processor (AP) and coprocessor (CP2): each business module calls the read / write interfaces of the IPC's streaming / block data transfer module (IPC FIFO buffer interface module / IPC block interface module, SBUF / SBLOCK) to transfer data, and then the IPC driver part completes the actual data transfer operation by transmitting inter-core communication messages (MSG) through inter-core communication.

[0029] Inter-core communication messages consist of the following four members: channel index (which is the index of the inter-core communication message), type (indicating the message type), and flag and value (optional, which can be filled in by the interface used).

[0030] The specific creation process of inter-core communication messages consists of two handshakes, such as... Figure 1 As shown, the specific creation process of the inter-core communication message includes: Host USER Thread (i.e., host side) 101, IPI / MAILBOX 102, IPI / MAILBOX 103, and Client USER Thread (i.e., slave side) 104. Among them, the host USER Thread and the client thread complete the handshake and channel creation through a combination of commands such as OPEN, OPEN ACK, and INITDONE. After the channel is created, subsequent inter-core communication messages are used to notify different cores of IPC read and write operations.

[0031] In this embodiment of the invention, the scenario is addressed when one end experiences an anomaly without prior warning:

[0032] After the inter-core communication message is created, the IPC thread only checks the flags in the inter-core communication message. The SBUF_EVENT_RDPTR_CHANGE or SBUF_EVENT_WRPTR_CHANGE flags are used to trigger different channels for read and write operations, while the handshake process depends on the type of the inter-core communication message.

[0033] In the above scenario, the slave thread has been successfully created and is waiting for the flag information in the inter-core communication message from the peer to perform channel (chn) operations, while the master user thread is in the stage where the channel has not been created. At this time, the master user thread needs to send a message of type MSG_TYPE_OPEN and wait for the peer's OPEN_ACK. Because the peer does not perform type judgment, the handshake falls into a deadlock of waiting without reply. This situation cannot be repaired after the slave restarts. After the slave restarts, it will actively send a message of type MSG_TYPE_OPEN (IPC open type command) to the master user thread. The master user thread will then think that this inter-core communication message is the OPEN_ACK that the peer replied to last time. The confusion of the handshake process leads to the master user thread and the slave being in an awkward situation where they can only recover by restarting again.

[0034] Based on this, embodiments of the present invention provide a device for restoring abnormal states of inter-core communication pathways. The specific scheme of a method for restoring abnormal states of inter-core communication pathways provided by the present invention is described below in conjunction with the accompanying drawings. Please refer to... Figure 2 This illustration shows a flowchart of an implementation of a method for restoring an abnormal state of inter-core communication pathways according to an embodiment of the present invention. The method includes:

[0035] 201, retrieve the running status of the master and slave devices.

[0036] Here, the operating status of the host and slave devices is monitored in real time to determine whether any abnormalities have occurred in their operating status.

[0037] 202. When the operating state of the host is abnormal and the operating state of the slave is normal, determine the type of inter-core communication message.

[0038] Here, abnormal states can be idle states, fault states, etc. If the master is in an abnormal state while the slave is running normally, it means that the master has encountered an abnormality and cannot notify the slave, so it restarts itself. Furthermore, the type of inter-core communication messages is polled to determine if the message type is a preset type.

[0039] In some possible implementations, when the host is in an abnormal state and the slave is in a normal state, the host is actively restarted and the streaming data transmission thread of the slave is determined; in the streaming data transmission thread, the type of the inter-core communication message of the host is determined.

[0040] Here, if an anomaly occurs on the master side while the slave side is running normally, the master side will actively restart and determine the module (IPC FIFO buffer interface module thread, SBUF thread) corresponding to the streaming data transmission thread on the slave side. In this module, additional judgments will be made on the inter-core communication messages on the slave side to analyze whether the type of the inter-core communication message is a preset type. This will facilitate message synchronization between the master side and the slave side by judging the type of the inter-core communication message.

[0041] 203. If the type of the inter-core communication message is a preset type, determine whether the host terminal has no alarm reset.

[0042] Here, the default type can be an inter-core communication message type that indicates that the channel is open (e.g., MSG_TYPE_OPEN, inter-core communication message to indicate that the channel is open).

[0043] In some possible implementations, if the inter-core communication type is "channel is opening," the data transmission method of the inter-core communication message is determined. Here, if the type is MSG_TYPE_OPEN (i.e., indicating the channel is opening), meaning the inter-core communication message's inter-core communication type indicates the channel is opening, then it is further determined whether the data transmission method of the inter-core communication message is message queue transmission (e.g., the data transmission method is using a message queue for data transmission corresponding to the inter-core communication message). If it is message queue transmission, then it is determined whether there is no alarm reset on the host side. For example, if the inter-core communication message type is MSG_TYPE_OPEN, then it is further determined whether there is no alarm reset on the host side. In this way, through multiple progressive judgments, the accuracy of the judgment can be improved.

[0044] In some embodiments, if the type of the inter-core communication message is not a preset type, the message type of the inter-core communication is polled until the type of the inter-core communication message is a preset type.

[0045] Here, if the type of the inter-core communication message is not MSG_TYPE_OPEN, i.e., it is a non-preset type, then it will run according to the old procedure, i.e., according to... Figure 1The process shown runs by polling the inter-core communication message type until the type of the inter-core communication message is MSG_TYPE_OPEN.

[0046] In some possible implementations, firstly, if the type of the inter-core communication message is not a preset type, the polling period for inter-core communication is obtained; here, the polling period can be a user-defined period or real-time polling. Then, when the host's operating state is abnormal and the slave's operating state is normal, the message type of the inter-core communication is polled based on the polling period until the type of the inter-core communication message is found to be a preset type. Here, in the scenario where the host's operating state is abnormal and the slave's operating state is normal, the slave polls the host's inter-core communication messages (i.e., the message queue data transmission module) in the SBUF thread until the type of the inter-core communication message is MSG_TYPE_OPEN (i.e., the channel is opening, which is also a preset type); thus, when the host's operating state is abnormal and the slave's operating state is normal, a timely and accurate path can be established between the slave and host, thereby achieving real-time message transmission.

[0047] In some possible implementations, when the host machine is in an abnormal operating state and the slave machine is in a normal operating state, the slave machine polls the message queue data transmission module for inter-core communication on the host machine according to a polling cycle to obtain the type of the inter-core communication message. Here, the message queue data transmission module is polled according to a polling cycle to determine whether the type of the inter-core communication message in that module is MSG_TYPE_OPEN.

[0048] 204. If the host terminal does not reset the alarm, a communication path is established between the host terminal and the slave terminal based on the initial handshake process.

[0049] Here, if there is no alarm reset on the master side, then the slave side responds to the master side according to the initial handshake process, thereby establishing a communication path between the master side and the slave side to ensure that data can be transmitted normally between the master side and the slave side.

[0050] In some possible implementations, step 104 above can be achieved through... Figure 3 The steps shown are to be implemented as follows:

[0051] 301. If the host terminal does not have an alarm reset, it responds to the slave terminal's command combination based on the initial handshake process.

[0052] Here, if the inter-core communication message type MSG_TYPE_OPEN is polled, it is determined that there is no alarm reset on the other end. Then, the slave end responds to the command combination according to the first handshake procedure to establish a communication path between the slave end and the master end.

[0053] In some possible implementations, if the host does not trigger an alarm reset, it responds to the host's enable command, enable acknowledgment command, and initialization end command based on the initial handshake process; and the enable command, enable acknowledgment command, and initialization end command are determined as the command combination. For example, the command combination includes: OPEN, OPEN_ACK, and INIT_DONE inter-core communication messages, etc.

[0054] 302. Based on the command combination, create a channel between the host and the slave.

[0055] Here, the slave device establishes a channel between itself and the master device by responding to a combination of commands from the master device, so that the slave device and the master device can communicate normally.

[0056] 303, reset the channel to the initial state to obtain a communication path between the host and the slave.

[0057] Here, after establishing the channel between the host and the slave, the channel information is reset according to the initial initialization state, so that the channel is the same as the initial initialization (INIT) state. In this way, the path between the host and the slave is re-established, and the transmission of service data is restored, so as to ensure that the path can restore communication as quickly as possible after a single-end abnormal reset.

[0058] In this embodiment of the invention, after obtaining the operating status of the host and slave, if the host's operating status is abnormal and the slave's operating status is normal, the type of inter-core communication message is determined. Thus, if the host is disconnected but the slave is operating normally, it is determined whether the type of the inter-core communication message indicates that the channel is open. If the type of the inter-core communication message indicates that the channel is open, it is determined whether the host has no alarm reset. If the host has no alarm reset, a communication path between the host and the slave is established based on the initial handshake process. Therefore, when the host experiences an anomaly and restarts itself without notifying the slave, the type of the inter-core communication message is determined. If the type of the inter-core communication message indicates that the channel is open, the path between the host and the slave is re-established, and the transmission of service data is restored, ensuring that communication can be restored as quickly as possible after a single-end abnormal reset.

[0059] In some embodiments, the method for restoring abnormal states of inter-nuclear communication pathways can be achieved through... Figure 4 The process framework shown is implemented as follows: Figure 4 As shown: The module (SBUF thread) corresponding to the streaming data transmission thread on the slave side of the client thread (i.e., slave 41) Figure 4 In the creation of SBUF (SBUF_CREAT) 43), additional checks are performed on the inter-core communication messages of the host side 42 (HOST USER THREAD). For messages of type other than MSG_TYPE_OPEN, the process continues as usual. The type of the inter-core communication message is polled by reading SBUF (SBUF_READ) 44. When an inter-core communication message of type MSG_TYPE_OPEN is polled, it is determined that the host side has no alarm reset (i.e., the type is determined, and it is predicted that the peer side has no alarm reset). Following the initial handshake process, the slave side responds to the host side's OPEN\OPEN_ACK\INIT_DONE inter-core communication messages (i.e., the initial handshake process is achieved by waiting for the inter-core communication message (MSG_WAIT 45)). The slave side's SBUF corresponds to the reverse channel initialization / initialization (CHN DEINIT\INIT), discarding existing data and resetting the address / pointer (ADDR\PTR) information, thereby ensuring that the host side process resets the channel information normally, ensuring that the channel is in the same INIT state as initially.

[0060] This invention provides a device for restoring abnormal states of inter-core communication pathways, such as... Figure 5 As shown, the device 500 includes:

[0065] In some possible implementations, the establishment module 504 is also used to respond to the combination of commands from the slave device based on the initial handshake process if the host device does not have an alarm reset.

[0066] Based on the command combination, a channel is created between the host and the slave.

[0076] In some possible implementations, the second determining module 503 is further configured to, when the operating state of the host is abnormal and the operating state of the slave is normal, based on the polling period, poll the module for transmitting message queue data of inter-core communication on the host by the slave to obtain the type of the inter-core communication message.
