[0040] Overview

[0041] As described in the background art, the processor is the core component of systems such as computers and controllers, responsible for executing all computing and processing tasks. The performance of the processor directly affects the overall operation effect of the system. Therefore, functional diagnosis of the processor is an important strategy to ensure the performance of the processor.

[0042] Currently, the processor is usually functionally diagnosed through a functional safety system. During the process of functionally diagnosing the processor, the functional safety system usually needs to disable interrupts to avoid the occurrence of task scheduling behaviors during the process of functionally diagnosing the processor, thereby ensuring the effective execution of the functional diagnosis of the processor. However, disabling interrupts makes the functional safety system unable to respond to tasks other than the functional diagnosis of the processor in a timely manner, which has a greater impact on the overall performance of the functional safety system; at the same time, during the process of disabling interrupts, it is necessary to save the task processing status before the interrupt, resulting in a large system overhead.

[0043] To solve the problem that the traditional method has a great impact on the overall performance of the functional safety system by prohibiting interrupts and causes a large system overhead, in the technical solution of this application, the function diagnosis method is applied to the first processing module in the function diagnosis system of the target processor. The first processing module runs in the user mode of the function diagnosis system. This method obtains the function to be diagnosed of the target processor and, when the function to be diagnosed meets the target conditions, sends a diagnosis request to the second processing module of the function diagnosis system. The diagnosis request is used to control the second processing module to perform an abnormal diagnosis on the function to be diagnosed of the target processor. The second processing module runs in the kernel mode of the function diagnosis system. The target conditions include prohibiting task scheduling during the diagnosis process. Thus, by setting up the function diagnosis system corresponding to the target processor and, when task scheduling needs to be prohibited during the diagnosis of the function to be diagnosed of the target processor, requesting the second processing module running in the kernel mode of the function diagnosis system to perform this function diagnosis, there is no need to prohibit interrupts for the function diagnosis system or the system in which the function diagnosis system runs, thereby avoiding the situation that the function diagnosis system or the system in which the function diagnosis system runs cannot respond in time to tasks other than the function diagnosis of the target processor due to prohibiting interrupts. Furthermore, during the process of performing function diagnosis on the target processor, the impact on the overall performance of the relevant system can be effectively reduced; at the same time, without prohibiting interrupts, there is no need to save the task processing state before the interrupt, etc., reducing the system overhead of the relevant system.

[0044] Based on the above inventive concept, the function diagnosis method provided in the embodiments of this specification will be described exemplarily below.

[0045] Exemplary Method

[0046] Please refer to Figure 1 , in an exemplary embodiment, a function diagnosis method is provided, which is applied to the first processing module in the function diagnosis system of the target processor. The first processing module runs in the user mode of the function diagnosis system. The method includes:

[0047] S101. Obtain the function to be diagnosed of the target processor.

[0048] Specifically, the target processor is the processor that needs to perform function diagnosis. The function diagnosis system of the target processor can be used to perform function diagnosis on various resource components of the target processor.

[0049] During implementation, the functional diagnosis system may adopt a microkernel operating system. Among them, the functional diagnosis system can be an independent system or a module in the microkernel operating system. For example, the functional diagnosis system can be a module added to a functional safety system or a processor management system that adopts a microkernel operating system. The functional diagnosis system may include a first processing module, and the first processing module can run in the user state of the functional diagnosis system.

[0050] The functions to be diagnosed of the target processor may include the functions to be abnormally diagnosed among the multiple functions of the target processor. Taking the target processor with the ARMv8-A architecture as an example, the multiple functions of the target processor may include various different types of functions, such as instruction pipelines, registers, interrupts, instruction sets, instruction caches, data caches, MMU (Memory Management Unit), data lines, and address lines. At the same time, each type of function may include at least one sub-function.

[0051] The first processing module can obtain the functions to be diagnosed of the target processor in real time. For example, the application side (such as the application layer of the functional safety system) can send functional diagnosis instructions to the functional diagnosis system according to a predetermined diagnosis cycle or other diagnosis requirements. The functional diagnosis instructions can be sent through data communication, or a diagnosis interface can be set in the functional diagnosis system to send functional diagnosis instructions to the functional diagnosis system by calling the diagnosis interface.

[0052] Optionally, the functions that need to be abnormally diagnosed among the functions of the target processor can also be pre-configured in the first processing module, and the diagnosis cycle and / or diagnosis order, etc. can be configured for each function that needs to be abnormally diagnosed. The first processing module can automatically determine the functions to be diagnosed of the target processor according to the pre-configured information.

[0053] S102. When the function to be diagnosed meets the target conditions, send a diagnosis request to the second processing module of the functional diagnosis system. The diagnosis request is used to control the second processing module to perform abnormal diagnosis on the function to be diagnosed of the target processor; the second processing module runs in the kernel state of the functional diagnosis system, and the target conditions include prohibiting task scheduling during the diagnosis process.

[0054] Specifically, the number of functions to be diagnosed of the target processor can be one or more. For any function to be diagnosed, the target conditions corresponding to the function to be diagnosed may include prohibiting task scheduling during the diagnosis process of the function to be diagnosed, that is, during the abnormal diagnosis process of the function to be diagnosed of the target processor, task switching is prohibited to ensure the effective diagnosis of the function to be diagnosed of the target processor.

[0055] The function diagnosis system may further include a second processing module, which may run in the kernel state of the function diagnosis system.

[0056] In implementation, when the function to be diagnosed meets the target conditions, a diagnosis request may be sent to the second processing module of the function diagnosis system. The diagnosis request may be used to control the second processing module to perform an abnormal diagnosis on the function to be diagnosed of the target processor, without disabling interrupts for the function diagnosis system or the system in which the function diagnosis system runs. Thus, it is avoided that disabling interrupts causes the function diagnosis system or the system in which the function diagnosis system runs to be unable to respond in time to tasks other than the function diagnosis of the target processor. Furthermore, during the process of performing function diagnosis on the target processor, the impact on the overall performance of the relevant system can be effectively reduced; at the same time, without disabling interrupts, there is no need to save the task processing state before the interrupt, etc., reducing the system overhead of the relevant system.

[0057] In an exemplary embodiment, the function diagnosis system further includes a function diagnosis interface module, and the function diagnosis interface module includes one or more diagnosis interfaces; obtaining the function to be diagnosed of the target processor includes:

[0058] Responding to a call operation and a parameter input operation on the diagnosis interface in the function diagnosis interface module, determining the function to be diagnosed of the target processor.

[0059] Specifically, the function diagnosis system may further include a function diagnosis interface module, and the diagnosis interface module may be used to receive a function diagnosis request sent by the application side. Among them, the function diagnosis interface module may include one or more diagnosis interfaces, which may be specifically set according to actual requirements.

[0060] For example, the function diagnosis interface module may include one diagnosis interface. The application side may request function diagnosis of the target processor by calling this diagnosis interface. At the same time, parameter data for characterizing the function to be diagnosed may be input to this diagnosis interface to request an abnormal diagnosis of the function to be diagnosed of the target processor. In addition, the function diagnosis interface may further include multiple diagnosis interfaces, and the multiple function diagnosis interfaces may correspond one-to-one to multiple predetermined function types of the target processor. In implementation, the application side may call the corresponding diagnosis interface according to the function diagnosis requirements and input parameter data for characterizing the sub-functions under the corresponding function type to the corresponding diagnosis interface to request an abnormal diagnosis of the sub-functions under the corresponding function type of the target processor.

[0061] In implementation, the application side can call the corresponding diagnostic interface in the function diagnostic interface module according to the function diagnosis requirements, and input parameter data to the corresponding diagnostic interface to request the function diagnostic system to perform an anomaly diagnosis on the corresponding function of the target processor. Among them, the application side can request the function diagnostic system to perform an anomaly diagnosis on the corresponding function of the target processor based on a predetermined diagnosis cycle. The predetermined diagnosis cycle can be determined according to the relevant function requirements of the application side, or can be the diagnosis cycle pre-configured in the application side. For example, the application side can request the function diagnostic system to perform an anomaly diagnosis on the corresponding function of the target processor after each power-on startup, and can also request the function diagnostic system to perform an anomaly diagnosis on the corresponding function of the target processor at intervals of a predetermined duration during operation. It can be understood that the application side can also request the function diagnostic system to perform an anomaly diagnosis on different functions of the target processor at different call times.

[0062] Thus, the diagnostic interface provides a unique access interface for the application side, shielding the differences in the hardware platforms of the processors from the application side, so that it can be applicable to the function diagnosis of processors of the same architecture located on different hardware platforms. That is, when processors of the same architecture are applied to different hardware platforms, there is no need to re-develop the function diagnostic system, which greatly saves human and material resources and shortens the development cycle of the function diagnostic system.

[0063] The first processing module can determine the function to be diagnosed of the target processor in response to the call operation and parameter input operation of the diagnostic interface in the function diagnostic interface module, so as to quickly and effectively determine the function to be diagnosed of the target processor. At the same time, through the call operation and parameter input operation of the diagnostic interface in the function diagnostic interface module, the function that needs to be diagnosed for the target processor can be flexibly selected according to the function diagnosis requirements, and the timing of performing the function diagnosis on the target processor can be flexibly configured. Furthermore, different function diagnosis requirements for the target processor can be met, and there is no need to perform an anomaly diagnosis on each function of the target processor in a fixed execution order every time the function diagnosis of the target processor is performed, improving the diagnosis efficiency.

[0064] In an exemplary embodiment, the function diagnostic interface module includes a plurality of the diagnostic interfaces corresponding one-to-one to a plurality of predetermined function types of the target processor; the function to be diagnosed includes sub-functions under at least one of the predetermined function types of the target processor;

[0065] The determining the function to be diagnosed of the target processor in response to the call operation and parameter input operation of the diagnostic interface in the function diagnostic interface module includes:

[0066] In response to a call operation on the diagnostic interface in the function diagnostic interface module, determine a target diagnostic interface, and use the predetermined function type corresponding to the target diagnostic interface as the target function type;

[0067] In response to a parameter input operation on the target diagnostic interface, determine the diagnostic parameters corresponding to the target function type;

[0068] Based on the diagnostic parameters corresponding to the target function type, determine the target sub-function under the target function type, and use the target sub-function under the target function type as the function to be diagnosed of the target processor.

[0069] Specifically, the function diagnostic interface module may include multiple diagnostic interfaces corresponding one by one to multiple predetermined function types of the target processor. The predetermined function type may be the function type that needs to be diagnosed for the processor of the corresponding architecture. For example, taking the processor of the ARMv8-A architecture as an example, the predetermined function types of the target processor may include instruction pipeline, register, interrupt, instruction set, instruction cache, data cache, MMU, data line, and address line, etc.

[0070] The function type of the function to be diagnosed may be one or more. For any function type, the function to be diagnosed may further include at least one sub-function under the function type.

[0071] In implementation, a target diagnostic interface may be determined in response to a call operation on the diagnostic interface in the function diagnostic interface module. That is, the target diagnostic interface may be the diagnostic interface called in the function diagnostic interface module. At the same time, the predetermined function type corresponding to the target diagnostic interface may be used as the target function type.

[0072] Among them, the number of target diagnostic interfaces may be one or more. That is, one diagnostic interface may be called at a time, or multiple diagnostic interfaces may be called simultaneously. For any target diagnostic interface, the diagnostic parameters corresponding to the corresponding target function type may be determined in response to a parameter input operation on the target diagnostic interface. The diagnostic parameters may include parameters representing sub-functions under the corresponding target function type. In addition, the diagnostic parameters may further include parameters representing the diagnostic conditions and / or diagnostic attributes of the corresponding sub-functions, etc. For example, the diagnostic condition may include abnormal diagnosis of the sub-function after the target processor reaches the target state, and the diagnostic attribute may include the diagnostic order.

[0073] During implementation, for any target function type, the target sub - functions under the target function type can be determined based on the diagnostic parameters corresponding to the target function type. Thus, the target sub - functions under each target function type can be obtained, and all the target sub - functions under each target function type are used as the functions to be diagnosed for the target processor, so that the functions that need to be diagnosed for the target processor can be flexibly selected.

[0074] In an exemplary embodiment, after sending the diagnostic request to the second processing module of the function diagnostic system, it further includes:

[0075] Obtain the abnormal diagnostic information returned by the second processing module;

[0076] Output the abnormal diagnostic information through the diagnostic interface corresponding to the function to be diagnosed.

[0077] Specifically, after sending the diagnostic request to the second processing module of the function diagnostic system, the abnormal diagnostic information returned by the second processing module can also be obtained. The abnormal diagnostic information can include the abnormal diagnostic result, and can also include the diagnostic process data and the module information of the corresponding function module in the target processor. Among them, the abnormal diagnostic result can include function abnormality and function normality; the diagnostic process data can include the intermediate data generated during the function diagnosis of the corresponding function module in the target processor.

[0078] During implementation, after receiving the diagnostic request, the second processing module can perform an abnormal diagnosis on the function to be diagnosed of the target processor based on the diagnostic program of the corresponding function pre - configured by itself, and return the abnormal diagnostic information to the first processing module.

[0079] After receiving the abnormal diagnostic information returned by the second processing module, the first processing module can output the abnormal diagnostic information of the function to be diagnosed to the application side through the diagnostic interface corresponding to the function type of the function to be diagnosed in the function diagnostic interface module, so that the application side can execute the corresponding control logic according to the abnormal diagnostic information of each function to be diagnosed of the target processor, thus ensuring the safe and reliable operation of the target processor, and when there is a function abnormality in the target processor, the abnormal condition of the target processor can be captured in time.

[0080] It can be understood that when the function diagnostic result is function abnormality, the application side can also call the corresponding fault handling process according to the diagnostic process data in the abnormal diagnostic information and the module information of the function module with function abnormality in the target processor, such as controlling the relevant relay to disconnect, etc., to perform the corresponding fault handling.

[0081] In an exemplary embodiment, sending the diagnostic request to the second processing module of the function diagnostic system includes:

[0082] Send a diagnostic request to the second processing module through the system call interface of the function diagnosis system.

[0083] Specifically, in the process of sending a diagnostic request to the second processing module, the first processing module can be implemented by means of system calls. For example, the first processing module can initiate a system call interrupt through the system call interface of the function diagnosis system. At the same time, the function type and diagnostic parameters of the function to be diagnosed are passed in through the system call interface parameters, so as to request the second processing module to perform a function diagnosis on the target processor according to the function type and diagnostic parameters. In implementation, the second processing module can obtain the function type and diagnostic parameters by querying the received call number, and determine the function to be diagnosed according to the function type and diagnostic parameters.

[0084] Thus, when the first processing module determines that the function to be diagnosed meets the target conditions, it can quickly and effectively request the second processing module to perform an abnormal diagnosis on the function to be diagnosed of the target processor, so as to effectively perform a function diagnosis on the target processor.

[0085] In an exemplary embodiment, the target conditions further include that the second processing module has access rights to the function to be diagnosed.

[0086] Specifically, the first processing module and the second processing module can be configured with different access rights to the target processor. For example, the first processing module cannot access the hardware resources of the target processor or execute privileged instructions, while the second processing module can access all the hardware resources of the target processor and can execute all instructions.

[0087] In implementation, for any function to be diagnosed, when the second processing module has access rights to the function to be diagnosed and the first processing module does not have access rights to the function to be diagnosed, it is determined that the function to be diagnosed meets the target conditions. When both the first processing module and the second processing module have access rights to the function to be diagnosed, it can be further determined whether task scheduling needs to be prohibited during the diagnosis process of the function to be diagnosed. If so, it is determined that the function to be diagnosed meets the target conditions. If not, it is determined that the function to be diagnosed does not meet the target conditions, so as to effectively perform a function diagnosis on the target processor.

[0088] In an exemplary embodiment, it further includes:

[0089] When the function to be diagnosed does not meet the target conditions, perform an abnormal diagnosis on the function to be diagnosed of the target processor.

[0090] Specifically, when the first processing module determines that the function to be diagnosed does not meet the target conditions, it can perform an abnormal diagnosis on the function to be diagnosed of the target processor through the corresponding diagnostic program of the function pre-configured by itself, and output the abnormal diagnosis information of the function to be diagnosed to the application side through the diagnostic interface corresponding to the function type of the function to be diagnosed in the function diagnostic interface module, so that the application side can execute the corresponding control logic according to the abnormal diagnosis information of each function to be diagnosed of the target processor, thereby ensuring the safe and reliable operation of the target processor, and when there is a function abnormality in the target processor, the abnormal condition of the target processor can be captured in time.

[0091] Among them, the abnormal diagnosis information may include an abnormal diagnosis result, and may also include diagnostic process data and module information of the corresponding function module in the target processor.

[0092] In an exemplary embodiment, another function diagnosis method is provided, which is applied to the second processing module in the function diagnosis system of the target processor. The second processing module runs in the kernel state of the function diagnosis system. The method includes:

[0093] When receiving the diagnosis request sent by the first processing module in the function diagnosis system, based on the diagnosis request, perform an abnormal diagnosis on the function to be diagnosed of the target processor;

[0094] Among them, the first processing module runs in the user state of the function diagnosis system. The first processing module is used to obtain the function to be diagnosed of the target processor, and when the function to be diagnosed meets the target conditions, send the diagnosis request to the second processing module; the target conditions include prohibiting task scheduling during the diagnosis process.

[0095] In an exemplary embodiment, after performing an abnormal diagnosis on the function to be diagnosed of the target processor, it further includes:

[0096] Return the abnormal diagnosis information corresponding to the function to be diagnosed to the first processing module, so as to control the first processing module to output the abnormal diagnosis information through the diagnostic interface corresponding to the function to be diagnosed.
