Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0058] Existing analysis tools for Intel C600 CPU MCE (Machine Check Exception) errors are typically third-party software or developer tools. Common analysis tools such as Intel Processor Diagnostic Tool, mcelog, Error Detection and Correction, and third-party hardware monitoring software (such as HWiNFO and AIDA64) must be pre-configured with the processor device to analyze the processor error. This makes analysis difficult for processors that have not been configured with these analysis tools, and is of limited use for devices that have already crashed.

[0059] In response to the situation in the existing technology that parsing tools need to be pre-configured to perform effective parsing, this application proposes a data processing method for processor-assisted error detection, which is applied to the Intel C600 platform to achieve parsing of processor errors, regardless of whether they are pre-configured, thereby improving the efficiency of processor device error parsing.

[0060] In some optional embodiments of this application, a data processing method for processor-assisted error detection is proposed. Figure 1 This is a flowchart of a data processing method for processor-assisted error detection proposed in this application, such as... Figure 1 As shown, the method includes the following steps:

[0061] S101: When auxiliary error detection request data is obtained, obtain error report data;

[0062] Error report data is report data used to indicate errors in the error-reporting processor;

[0063] S102: Perform register feature-based identification processing on the error report data to obtain register status data;

[0064] Register status data is data used to represent the contents of processor registers;

[0065] S103: Perform error detection and location processing on the register status data, and generate an auxiliary error detection report based on the error detection and location results.

[0066] In some optional embodiments of this application, a data processing method for processor-assisted error detection is proposed to obtain error location result data by performing error detection processing based on register state information. Figure 2 This is a flowchart of a data processing method for processor-assisted error detection proposed in this application, such as... Figure 2 As shown, the method includes the following steps:

[0067] S201: performing functional feature-based identification processing on register state data to obtain first functional feature register state data, second functional feature register state data, and third functional feature register state data;

[0068] In an optional embodiment of the present application, the registers include global control and status registers and multiple error reporting register groups. Based on the information provided by different registers, the functions and data corresponding to different registers are identified, and processor error detection and positioning are performed based on the different registers and their corresponding data.

[0069] S202: Determine the first error data based on the status data of the first functional feature register;

[0070] The first error data is data for indicating the error hardware of the processor; the first function characteristic register provides information about the machine check architecture of the processor.

[0071] S203: Determine the second error data based on the status data of the second functional feature register;

[0072] The second error data is status data used to indicate a processor check exception. The second function feature register provides the current state of the processor after a machine check exception occurs. For example, the RIPV (restart IP valid) flag in the register, bit 0—indicates that when a machine check exception occurs, program execution can be reliably restarted at the instruction pointed to by the instruction pointer pushed on the stack. After clearing this flag, the program cannot be reliably restarted at the pushed instruction pointer. The EIPV (error IP valid) flag, bit 1—indicates that the instruction pointed to by the instruction pointer pushed on the stack when a machine check exception is generated is directly related to the error. After clearing this flag, the pointed-to instruction may not be related to the error. The MCIP (machine check in progress) flag, bit 2—indicates that a machine check exception has been generated. Software can set or clear this flag. When MCIP is set, the occurrence of a second machine check event will cause the processor to enter a shutdown state. LMCE_S (local machine check exception signaled), bit 3—indicates that a local machine check exception has been generated, which means that the current machine check event is only passed to this logical processor.

[0073] S204: Determine third error data according to the third functional feature register state data;

[0074] The third error data is data used to indicate the processor error status. The third feature register is an error status register. For example, if the VAL (valid) flag is set, the status data of each error status register contains information related to a machine check error. Software is responsible for clearing the error status register by explicitly writing a 0; writing a 1 causes a general protection exception.

[0075] S205: Obtain error detection and location result data based on the first error data, the second error data, and the third error data.

[0076] In some optional embodiments of the present application, a data processing method for processor-assisted debugging is proposed to generate an assisted debugging report based on debugging location result data. The method includes:

[0077] The error detection and positioning result data is identified and processed to obtain error address data and error type data; the error address data in the error detection and positioning result data is matched based on the status data to obtain abnormal check status data and error status data corresponding to the error address data; and an auxiliary error detection report is generated based on the error address data and the corresponding error type data, abnormal check status data, and error status data.

[0078] In some optional embodiments of the present application, a data processing method for processor-assisted error detection is provided. After generating an assisted error detection report based on error detection location data, the method further includes generating a solution for the processor error based on the assisted error detection report, including:

[0079] The error report data is processed based on process type identification to obtain process type data, wherein the process type is a process type used to represent the corresponding processor error; the solution measures corresponding to the process type data are matched in a preset system error database to obtain measure suggestion data.

[0080] In an optional embodiment of the present application, if the server error is a memory error, by identifying process-related data, including process types, process types include user space processes, operating system kernel processes and virtual machine processes, respectively, the solution to the server error is determined for the above process types and error report data, and the suggested solution is output.

[0081] In some optional embodiments of this application, a data processing method for processor-assisted error detection is proposed to perform error location processing on register state data. The method includes:

[0082] The register status data is processed based on error keywords to obtain error keyword data; the error location data corresponding to the error keyword data is matched in a preset system error database to obtain error location result data, wherein the error location result data includes error address data and error type data.

[0083] For example, error information is received, feature fields of the error information are extracted, and error keywords are extracted and processed to obtain error keyword data; the error detection data corresponding to the error keywords are stored in the preset system error database, and the corresponding processor error data is matched according to the error keywords to realize the positioning processing of the server error, wherein the processor error data includes the error address and error type.

[0084] In some optional embodiments of this application, a processor-assisted error detection system is proposed, applicable to the Intel C600 platform, to parse processor MCE errors. The processor-assisted error detection system includes: a communication module and an error detection module, wherein...

[0085] The communication module communicates with the error processor device to obtain error report data from the error processor; the error detection module executes data processing methods for processor-assisted error detection to achieve error detection of the error processor.

[0089] The error detection module 33 is used to perform error detection and positioning processing on the register status data, and generate an auxiliary error detection report according to the error detection and positioning result.

[0090] In some alternative embodiments of this application, a data processing apparatus for processor-assisted error detection is proposed. Figure 4 This application proposes a schematic diagram of a data processing device for processor-assisted error detection, such as Figure 4 As shown, including:
