Description

Technical Field

[0001] This invention relates to the field of vehicle computing platform technology, and in particular to a central computing platform kernel monitoring method, apparatus, device, and storage medium. Background Technology

[0002] The central in-vehicle computing platform is the core architecture for the development of intelligent vehicles. It aims to integrate the dispersed computing resources, data processing capabilities, and functional modules within the vehicle to form a unified central control hub. By centrally managing the in-vehicle electronic systems, it enables data interoperability, functional collaboration, and intelligent decision-making, and is a key technology driving the transformation of automobiles into "intelligent mobile terminals."

[0003] In multi-core central in-vehicle computing platforms, kernel health management is a critical step in ensuring stable system operation, performance optimization, and hardware lifespan. If kernel hardware failures (such as circuit anomalies or cache errors) or software anomalies (such as deadlocks or memory leaks) are not managed promptly, they can lead to the collapse of the entire in-vehicle system. Common kernel monitoring tools include Preload, Netlink Connector, Audit, Syscallhook, and IPRmon; however, these methods have drawbacks in terms of compatibility and performance.

[0004] Therefore, there is an urgent need to design a scheme for monitoring the health status of the kernel in order to monitor and manage the central computing platform. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a method, apparatus, device and storage medium for monitoring the kernel of a central computing platform.

[0006] In a first aspect, embodiments of the present invention provide a method for monitoring the kernel of a central computing platform, comprising:

[0007] The system resource information of the target kernel is acquired in real time, and the corresponding HAM action is triggered when the first type of HAM condition is triggered.

[0008] It acquires key process information of the target kernel in real time, and responds to the corresponding HAM action when the second type of HAM condition is triggered;

[0009] The system periodically retrieves heartbeat messages from the target kernel. If no heartbeat message is received within a preset time, the target kernel is restarted.

[0010] In one embodiment, the target kernel includes at least: a high availability manager, a service level manager, a HAM entity, a health manager, and a diagnostic fault code manager.

[0011] In one embodiment, the service level manager is used to start or restart an application consisting of multiple processes started in a specific order.

[0013] In one embodiment, when a first type of HAM condition is triggered, the corresponding HAM action is responded to, including:

[0014] The system monitor in the target kernel acts as a HAM entity and acquires the CPU and memory usage in the target kernel in real time.

[0015] When the utilization rate of the CPU and / or the memory exceeds a preset threshold, the first type of HAM condition is triggered.

[0016] The high availability manager in the target kernel, based on the first type of HAM condition, either reports to the diagnostic fault code manager in the target kernel or restarts the relevant processes by reporting to the service level manager in the target kernel.

[0018] The system monitor establishes a connection with the high availability manager by calling a function. When the CPU and / or memory usage exceeds a preset threshold, it obtains the first type of HAM condition that has been triggered.

[0019] The high availability manager obtains the triggered first type of HAM condition, configures the corresponding HAM action, and sends the corresponding pulse information to the health manager;

[0020] After receiving the pulse information, the health manager sends a diagnostic fault code report corresponding to the fault to the diagnostic fault code manager.

[0021] The diagnostic fault code manager sends fault data to the microprocessor server;

[0022] The microprocessor server sends fault data to the auxiliary monitoring kernel.

[0023] In one embodiment, when a second type of HAM condition is triggered, the corresponding HAM action is responded to, including:

[0024] The application sets the second type of HAM conditions at each critical process node and monitors the anomalies of each critical process node in real time.

[0025] When the application encounters an error and needs to exit the process, the second type of HAM condition is triggered.

[0026] The high availability manager in the target kernel, based on the second type of HAM condition, either reports to the diagnostic fault code manager in the target kernel or restarts the relevant processes by reporting to the service level manager in the target kernel.

[0027] Secondly, embodiments of the present invention provide a central computing platform kernel monitoring device, comprising:

[0031] Thirdly, embodiments of the present invention provide an electronic device, the electronic device comprising:

[0032] At least one processor; and a memory communicatively connected to the at least one processor; wherein,

[0033] The memory stores a computer program that can be executed by at least one processor, such that the at least one processor is able to perform the steps of the method according to any embodiment of the present invention.

[0034] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer instructions that are used to cause a processor to execute the steps of any embodiment of the method of the present invention.

[0051] Figure 1This is a flowchart illustrating a central computing platform kernel monitoring method provided in an embodiment of the present invention. This embodiment is applicable to the health management of the kernel in a multi-core central computing platform. The method can be executed by a central computing platform kernel monitoring device, which can be implemented in software and / or hardware and can be configured in an electronic device.

[0052] like Figure 1 As shown, the method specifically includes:

[0053] S1: Real-time acquisition of system resource information of the target kernel; when the first type of HAM condition is triggered, respond to the corresponding HAM action.

[0054] S2 acquires key process information of the target kernel in real time, and responds to the corresponding HAM action when the second type of HAM condition is triggered;

[0055] S3: Periodically obtain heartbeat messages from the target kernel. If no heartbeat message is received within a preset time, restart the target kernel.

[0056] Figure 2 This is a structural block diagram of an application scenario of the method provided in the embodiments of the present invention, such as... Figure 2 As shown, in one embodiment, the central computing platform includes at least two kernels: an A kernel and an M kernel. The A kernel is the target kernel in this embodiment, while the M kernel serves as an auxiliary monitoring kernel. The target kernel includes at least the following: a High Availability Manager (HAM), a Service Level Manager (SLM), a HAM entity handle, a Health Manager, and a Diagnostic Trouble Code Manager (DTC).

[0057] HAM is the High Availability Manager in the QNX system, similar to a software watchdog. Its main function is to monitor the status of system processes and ensure that critical processes can recover quickly after a failure, thereby ensuring the availability of the entire system. It can perform multi-level recovery when system services or processes fail, are unresponsive, or provide unacceptable levels of service.

[0058] SLM is a module in the QNX system used to manage and control system startup and operation. It allows developers to define and manage the startup order and dependencies of various components during system startup, thereby ensuring that the system can start and run reliably.

[0059] In one embodiment, the Service Level Manager (SLM) is used to start or restart an application (APP) consisting of multiple processes started in a specific order. The startup order of the processes is determined by an XML configuration file, which supports dependency management and waiting mechanisms. The SLM can be controlled using the slmctrl command or configured in detail through the XML configuration file. In cases where an application (APP) exception requires process restart, the Service Level Manager (SLM) restarts the application (APP).

[0060] In one embodiment, the HAM entity includes a system monitor and key processes in the application. The system monitor and key processes in the application are marked using HAM entity handles. By marking the system monitor, processor or memory usage can be quickly located; by marking the key processes, abnormal conditions in each key process can be quickly located.

[0061] A handle is an identifier used to identify an object or item. Each entity handle is unique and used to identify a specific entity object or item, ensuring that the program can accurately locate and distinguish different entities during operation. The HAM entity handle is a valid handle returned when a process is attached to the HAM. The HAM entity handle allows the program to interact with the HAM, enabling monitoring and management of the process state. Through the HAM entity handle, operations such as starting, stopping, and restarting processes can be performed.

[0062] It should be noted that the A core is mainly used for high-performance application processing, focusing on running complex operating systems and applications; while the M core is designed for microcontroller applications, mainly used for real-time control and low-power applications in embedded systems, focusing on real-time response capabilities, and can quickly react to external events.

[0063] Specifically, monitoring the target kernel involves two aspects: First, the target kernel notifies the auxiliary monitoring kernel of its working status via heartbeat communication. The auxiliary monitoring kernel is responsible for monitoring the working status of the target kernel and performing corresponding health management based on different working statuses. If the auxiliary monitoring kernel does not receive a heartbeat message within a specified time (10 seconds), it records the fault and restarts the target kernel. Second, the target kernel also relies on the HAM mechanism of its internal QNX system to monitor critical service processes and its own system resource utilization (such as CPU and memory).

[0064] Figure 3 This is a flowchart illustrating a monitoring system resource process according to an embodiment of the present invention, such as... Figure 3 As shown, in one embodiment, when the first type of HAM condition is triggered, the corresponding HAM action is responded to, specifically including:

[0065] S110, the system monitor in the target kernel acts as a HAM entity and obtains the CPU and memory usage in the target kernel in real time;

[0066] S120, when the CPU and / or memory utilization exceeds a preset threshold, the first type of HAM condition is triggered;

[0067] S130, the high availability manager in the target kernel, based on the first type of HAM condition, either reports to the diagnostic fault code manager in the target kernel, or restarts the relevant processes by reporting to the service level manager in the target kernel.

[0068] It should be noted that the system monitor periodically monitors the resource utilization (CPU and memory) of the target kernel (A core). When the CPU and / or memory utilization exceeds 85% of the system, the system monitor triggers the High Availability Manager (HAM) response through the HAM interface. The High Availability Manager (HAM) executes the corresponding HAM action according to the configuration of the Health Manager (reporting DTC to the DTC Manager via IPC). At the same time, the Health Manager can also control the restart of one or more related services through the Service Level Manager (SLM).

[0069] In one embodiment, the process of monitoring CPU utilization includes:

[0070] First, the system controller establishes a connection with the high availability manager. When the CPU utilization exceeds the preset threshold (85%), the HAM condition is triggered, and the corresponding HAM condition is obtained.

[0071] For example, the function ham_attach_self("system_monitor",0,0,0,0) is called to establish a connection with the high availability manager, and the function ham_entity_condition_raise(entity,1,cpu_high_value,1) is called to obtain the corresponding HAM condition.

[0072] Then the high availability manager obtains the corresponding HAM conditions, configures the corresponding HAM actions, and sends the corresponding pulse information to the health manager;

[0073] For example, the function ham_condition_raise(entity," cpu_high",1,cpu_high_value,1,0) is called to obtain the corresponding HAM condition; the function ham_action_notify_pulse is called to configure the corresponding HAM action.

[0074] After receiving the pulse information, the health manager then sends the corresponding diagnostic fault code report to the diagnostic fault code manager.

[0075] For example, the function megaipc_pubsub_publish can be called to send a diagnostic fault code report corresponding to the fault.

[0076] Then the diagnostic fault code manager sends fault data to the microprocessor server;

[0077] For example, calling the function megaipc_pubsub_publish sends fault data.

[0078] Finally, the microprocessor server sends fault data to the auxiliary monitoring kernel;

[0079] For example, call the function send_message(ipcf 2) to send fault data.

[0080] Correspondingly, the process of monitoring memory usage is similar to that of monitoring CPU usage.

[0081] In one embodiment, the specific process of monitoring memory usage includes:

[0082] First, the system controller establishes a connection with the high availability manager. When the memory usage exceeds the preset threshold (85%), the HAM condition is triggered, and the corresponding HAM condition is obtained.

[0083] For example, the function ham_attach_self("mem_monitor",0,0,0,0) is called to establish a connection with the high availability manager, and the function ham_entity_condition_raise(entity,1,mem_high_value,1) is called to obtain the corresponding HAM condition.

[0084] Then the high availability manager obtains the corresponding HAM conditions, configures the corresponding HAM actions, and sends the corresponding pulse information to the health manager;

[0085] For example, call the function ham_condition_raise(entity," mem_high",1,mem_high_value,1,0) to get the corresponding HAM condition; call ham_action_notify_pulse to configure the corresponding HAM action.

[0086] After receiving the pulse information, the health manager then sends the corresponding diagnostic fault code report to the diagnostic fault code manager.

[0087] For example, the function megaipc_pubsub_publish can be called to send a diagnostic fault code report corresponding to the fault.

[0088] Then the diagnostic fault code manager sends fault data to the microprocessor server;

[0089] For example, calling the function megaipc_pubsub_publish sends fault data.

[0090] Finally, the microprocessor server sends fault data to the auxiliary monitoring kernel;

[0091] For example, call the function send_message(ipcf 2) to send fault data.

[0092] Figure 4 A flowchart illustrating the monitoring of critical processes provided in this embodiment of the invention is shown below. Figure 4 As shown, in one embodiment, when the second type of HAM condition is triggered, the corresponding HAM action is responded to, specifically including:

[0093] S210, the application sets the second type of HAM conditions at each critical process node and monitors the anomalies of each critical process node in real time.

[0094] S220, when an application encounters an error and needs to exit the process, the second type of HAM condition is triggered;

[0095] S230, the high availability manager in the target kernel, based on the second type of HAM condition, either reports to the diagnostic fault code manager in the target kernel, or restarts the relevant processes by reporting to the service level manager in the target kernel.

[0096] It should be noted that the application (app) sets HAM conditions at critical program points. When the conditions are met (e.g., a serious error occurs and the process needs to exit), the High Availability Manager (HAM) is triggered to respond through the HAM interface. The High Availability Manager (HAM) executes the corresponding HAM actions according to the Health Manager's configuration (reporting DTCs to the DTC Manager via IPC). At the same time, the Health Manager can also control the restart of one or more related services through the Service Level Manager (SLM).

[0097] The technical solution in this embodiment of the invention monitors the target kernel by acquiring its system resource information and key process information. When the CPU and / or memory usage of the target kernel exceeds a preset threshold, a first type of HAM condition is triggered. When an application encounters an error and needs to exit, a second type of HAM condition is triggered. By treating the system monitor and key processes in the application as HAM entities and setting corresponding HAM conditions and actions, the target kernel achieves internal management of itself. Simultaneously, the target kernel sends heartbeat messages to the auxiliary monitoring kernel. If the auxiliary monitoring kernel does not receive a heartbeat message within a preset time, it restarts the target kernel, enabling external management of the target kernel by other kernels.

[0098] Based on the same inventive concept, embodiments of the present invention also provide a central computing platform kernel monitoring device.

[0099] The first response module 100 is used to obtain the system resource information of the target kernel in real time, and respond to the corresponding HAM action when the first type of HAM condition is triggered.

[0100] The second response module 200 is used to acquire key process information of the target kernel in real time, and respond to the corresponding HAM action when the second type of HAM condition is triggered.

[0101] The restart module 300 is used to periodically obtain heartbeat messages from the target kernel. If no heartbeat message is received within a preset time, the target kernel is restarted.

[0104] In some embodiments, the processor 101, memory 102, and I / O interface 103 are interconnected via bus 104, and thus connected to other components of the computing device.
