Description

Technical Field

[0001] This invention relates to the field of memory testing technology, specifically to methods, apparatus, equipment, and media for handling memory errors that cause system crashes. Background Technology

[0002] ARM architecture chips are becoming increasingly popular due to their advantages such as low power consumption, low price, and strong scalability. In the server field, x86 architecture servers have always been dominant, but in recent years, due to the advantages of ARM architecture chips, the market share of ARM servers has gradually increased. Since the stability of ARM architecture servers is lower than that of x86 servers, the maintainability of ARM architecture servers has gradually become an important concern. As an important component of servers, memory reliability plays a crucial role in maintenance.

[0003] When a server runs various applications, it frequently interacts with the CPU, memory, hard drive, etc., generating various pressures. During the application process, the memory will inevitably generate uncorrectable errors (UCE) or catastrophic fault errors (IERR). The BIOS sends the fault information to the BMC and OS, which record it in the corresponding fault log.

[0004] Uncorrectable memory errors (UCE) or catastrophic error errors (IERR) generated by memory are not handled and are only reported to the log. Although the log can clearly show the current problem, it also causes the system to crash. While keeping the crash status makes it easier to analyze, it affects operations. When these errors occur, the entire system crashes, affecting program operation, and consequently, customers cannot access the system, affecting user experience and causing losses. Summary of the Invention

[0005] Uncorrectable memory errors (UCE) or catastrophic error errors (IERR) generated by memory are not handled and are only reported to the log. Although the log can clearly show the current problem, it also causes the system to crash. Although the crash can be kept for easy analysis, it affects operation. When these errors occur, the entire system crashes, affecting the operation of programs. This invention provides a method, device, equipment and medium for handling the problem of crash caused by memory errors.

[0006] In a first aspect, the present invention provides a method for handling system crashes caused by memory errors, comprising the following steps:

[0007] Detect memory errors and distinguish error types;

[0008] Determine if the error type is a memory-correctable error;

[0009] If so, send the fault information to the BMC and record the fault in the fault log;

[0010] Otherwise, downgrade the current memory error;

[0011] Determine whether the number of memory errors after downgrading reaches the corresponding module register threshold;

[0012] If so, physically isolate the faulty memory.

[0013] Otherwise, send a memory degradation error log to the BMC.

[0014] As a preferred embodiment of the technical solution of the present invention, the method includes:

[0015] When the memory error type is an uncorrectable error, the uncorrectable error is downgraded to a downgraded uncorrectable error.

[0016] Determine whether the number of uncorrectable errors after the current downgrade has reached the threshold of the uncorrectable error module register after the downgrade;

[0017] If not, proceed as follows: Send a memory degradation error log to the BMC;

[0018] If so, the procedure is to physically isolate the faulty memory.

[0019] As a preferred embodiment of the technical solution of the present invention, the method further includes:

[0020] When the memory error type is a catastrophic failure, the catastrophic failure is downgraded to a downgraded catastrophic failure.

[0021] Determine whether the number of catastrophic failures after degradation reaches the threshold of the catastrophic failure module register after degradation;

[0022] If not, proceed as follows: Send a memory degradation error log to the BMC;

[0023] If so, the procedure is to isolate the faulty memory.

[0024] The processing procedure is as follows: When a memory fault is detected, the fault type is first distinguished. For correctable errors (CE), no downgrading is performed; a fault message is sent to the BMC, and a fault log is recorded. This type of error will not cause a system crash. When an uncorrectable memory error (UCE) is detected, to prevent a system crash, the UCE needs to be downgraded. When a UCE is downgraded to a D-UCE fault, it is necessary to determine whether the current number of D-UCEs has reached the D-UCE module register threshold A. If the threshold is not reached, no crash will occur, and a fault message is sent to the BMC to record the fault log. If the threshold A is reached, to prevent a system crash, the faulty memory is physically isolated, which is equivalent to not configuring the faulty memory, thus preventing a crash. When a catastrophic memory error type (IERR) is detected, indicating a serious memory failure, the fault is downgraded to D-IERR. The system checks if the number of D-IERR faults has reached the D-IERR module register threshold B. If it hasn't reached threshold B, a fault message is sent to the BMC, and a fault log is recorded. If it reaches threshold B, the memory is isolated to prevent system crashes. The D-IERR module register threshold B is less than the D-UCE module register threshold A, meaning the number of D-IERR downgrades is low.

[0025] As a preferred embodiment of the technical solution of the present invention, after the step of determining whether the error type is a memory-correctable error, the following steps are included:

[0026] The procedure for handling memory degradation errors is set in the correctable machine check interrupt code within the operating system kernel;

[0028] Configure data parsing functionality for the machine verification library within the correctable machine check interrupt handling;

[0029] Obtain a correctable machine check interrupt and handle memory errors through a program that processes memory degradation errors;

[0030] The specific fault memory address and error type can be obtained by correcting machine check interrupts and parsing the data of the machine verification library.

[0031] If the error type is a degradation error, the following steps are performed: Send a memory degradation error log to the BMC;

[0032] If the error type is a correctable memory error, the steps are: send the fault information to the BMC and record the fault in the fault log.

[0033] As a preferred embodiment of the technical solution of the present invention, the step of sending the memory degradation error log to the BMC includes the following:

[0039] Based on the analysis results, an isolation command is sent, and hardware configuration is performed according to the isolation command to isolate the faulty memory.

[0040] As a preferred embodiment of the technical solution of the present invention, the step of obtaining information about faulty memory based on memory error information includes:

[0041] Send a command to retrieve memory information based on the memory error message;

[0043] A preset address range is generated based on the first address and the preset address offset information;

If not, it triggers the sending module to send the memory downgrade error log to the BMC; if so, it triggers the isolation module to perform physical isolation of the faulty memory.

To enable those skilled in the art to better understand the technical solutions in the invention, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the invention. When memory generates an uncorrectable error (UCE) or a catastrophic fault error (IERR), the BIOS performs graded processing, using a combination of faulty memory isolation and fault degradation to isolate a single faulty memory without affecting the use of other memory, and optimize the fault log. The main purpose is to prevent system crashes and ensure normal business operations, while simultaneously clearly recording memory log information for convenient and timely maintenance. Figure 1 As shown, this embodiment of the invention provides a method for handling system crashes caused by memory errors, including the following steps:

[0090] Step 1: Detect memory errors and distinguish the error type;

[0091] Step 2: Determine if the error type is a memory-correctable error;

[0092] If yes, proceed to step 3; otherwise, proceed to step 4.

[0093] Step 3: Send fault information to BMC and record the fault in the fault log;

[0094] Step 4: Downgrade the current memory error;

[0095] Step 5: Determine whether the number of memory errors after downgrading reaches the corresponding module register threshold;

[0096] If yes, proceed to step 6; otherwise, proceed to step 7.

[0097] Step 6: Physically isolate the faulty memory;

[0098] Step 7: Send the memory degradation error log to the BMC.

[0099] Memory failure types are categorized as follows: Uncorrectable error (UCE), Correctable memory error (CE), Degraded uncorrectable error (D-UCE), Catastrophic failure (IERR), and Degraded catastrophic failure (D-IERR).

[0100] Uncorrectable errors (UCE) and catastrophic failures (IERR) can both cause system crashes. However, correctable memory errors (CE), degraded uncorrectable errors (D-UCE), and degraded catastrophic failures (D-IERR) will not cause system crashes. The difference is that correctable memory errors (CE) are not limited in number; even an infinite number of correctable errors (CE) will not cause a system crash. Degraded uncorrectable errors (D-UCE) and degraded catastrophic failures (D-IERR) are limited in number. When they exceed a certain value in the D-UCE module register and D-IERR module register, respectively, physical isolation of the faulty memory is performed, preventing system crashes.

[0101] like Figure 2 As shown, this embodiment of the invention provides a method for handling system crashes caused by memory errors, including the following steps:

[0102] S1: Detect memory error information;

[0103] S2: Determine the error type;

[0104] When the error type is a correctable memory error, execute S3; when the memory error type is an uncorrectable memory error, execute S4; when the memory error type is a catastrophic failure, execute S8.

[0105] S3: Send fault information to BMC and record fault log; execute step S10;

[0106] S4: Downgrade the uncorrectable error to a downgraded uncorrectable error;

[0107] S5: Determine whether the number of uncorrectable errors after the current downgrade has reached the threshold of the uncorrectable error module register after the downgrade;

[0108] If not, proceed to step S6; if yes, proceed to step S7.

[0109] S6: Send the memory degradation error log to the BMC; execute step S10;

[0110] S7: Physically isolate the faulty memory.

[0111] S8: Downgrade the catastrophic failure to a downgraded catastrophic failure.

[0112] S9: Determine whether the number of catastrophic failures after degradation has reached the threshold of the catastrophic failure module register after degradation;

[0113] If not, execute S6 to send a memory degradation error log to the BMC;

[0114] If so, execute S7 to isolate the faulty memory.

[0115] S10: After receiving the log, the BMC obtains the memory location based on the faulty memory address and outputs a prompt message.

[0116] The processing procedure is as follows:

[0117] When the BIOS detects a memory fault, it first distinguishes the fault type. For correctable errors (CE), no downgrading is performed; a fault message is sent to the BMC, and a fault log is recorded. This type of error will not cause a system crash. When an uncorrectable memory error (UCE) is detected, to prevent a system crash, the UCE needs to be downgraded. When a UCE is downgraded to a D-UCE fault, it is necessary to check whether the current number of D-UCEs has reached the D-UCE module register threshold A. If the threshold is not reached, no crash will occur, and a fault message is sent to the BMC, which records the fault log. If the threshold A is reached, to prevent a system crash, the faulty memory is physically isolated, which is equivalent to not configuring the faulty memory, thus preventing a crash. When a catastrophic memory error type (IERR) is detected, indicating a serious memory failure, the fault is downgraded to D-IERR. The system checks if the number of D-IERR faults has reached the D-IERR module register threshold B. If it hasn't reached threshold B, a fault message is sent to the BMC, and a fault log is recorded. If it reaches threshold B, the memory is isolated to prevent system crashes. The D-IERR module register threshold B is less than the D-UCE module register threshold A, meaning the number of D-IERR downgrades is low.

[0118] This invention provides a method for handling system crashes caused by memory errors. In the above embodiments, the specific implementation process of sending logs to the BMC includes:

[0119] The procedure for handling memory degradation errors is set up in the correctable machine check interrupt code within the operating system kernel; the interrupt type for generating correctable memory errors is set to correctable machine check interrupt; the data parsing function for the machine check library is set up in the correctable machine check interrupt handling; the correctable machine check interrupt is obtained, and the memory error is handled by the procedure for handling memory degradation errors; the specific faulty memory address and error type are obtained through the data parsing function of the machine check library by the correctable machine check interrupt; if the error type is a degradation error, the following steps are executed: send the memory degradation error log to the BMC; if the error type is a correctable memory error, the following steps are executed: send the fault information to the BMC and record the fault log.

[0120] The specific steps for isolating faulty memory in the above embodiments include:

[0121] S71: Obtain memory information of the faulty memory;

[0122] S72: Send a memory isolation message, the isolation message carrying memory information that needs to be isolated and isolation information;

[0123] S73: Analyze the memory information that needs to be isolated and the isolation information in the memory isolation message;

[0124] S74: Send an isolation command based on the analysis results, and perform hardware configuration based on the isolation command to isolate the faulty memory.

[0125] In the above embodiments, the step of obtaining information about faulty memory based on memory error information includes:

[0126] Send an instruction to retrieve memory information based on memory error information; respond to the retrieval instruction and determine a first address containing a preset string representing memory information; generate a preset address range based on the first address and preset address offset information; read the preset string stored within the preset address range; determine the memory information targeted by the retrieval instruction based on the preset string; and return the determined memory information based on the retrieval instruction.

[0127] Memory fault types are categorized as follows: Uncorrectable Errors (UCE), Correctable Memory Errors (CE), Degraded Uncorrectable Errors (D-UCE), Catastrophic Faults (IERR), and Degraded Catastrophic Faults (D-IERR). Uncorrectable errors (UCE) and catastrophic faults (IERR) can both cause system crashes. Correctable errors (CE), degraded uncorrectable errors (D-UCE), and degraded catastrophic faults (D-IERR) do not cause system crashes. Correctable errors (CE) are unlimited in number; even an infinite number of correctable errors (CE) will not cause a system crash. Degraded uncorrectable errors (D-UCE) and degraded catastrophic faults (D-IERR) are limited in number. When the number exceeds a certain value in the D-UCE module register and the D-IERR module register, respectively, physical memory isolation is implemented, preventing system crashes.

[0128] like Figure 3 As shown, the present invention provides a problem-solving device for memory error-induced crashes, including a detection module, a type judgment module, a sending module, a degradation processing module, a quantity judgment module, and an isolation processing module;

[0129] The detection module is used to detect memory errors and distinguish the error type;

[0130] The type determination module is used to determine whether the error type is a memory-correctable error;

[0131] The sending module is used to send fault information to the BMC and record fault logs.

[0132] The degradation processing module is used to degrade the current memory error; when the memory error type is an uncorrectable error, it degrades the uncorrectable error to a downgraded uncorrectable error; when the memory error type is a catastrophic failure, it degrades the catastrophic failure to a downgraded catastrophic failure.

[0133] The quantity judgment module is used to determine whether the number of memory errors after degradation has reached the corresponding module register threshold; it is also used to determine whether the number of currently downgraded uncorrectable errors has reached the downgraded uncorrectable error module register threshold. If not, it triggers the sending module to send memory degradation error logs to the BMC; if so, it triggers the isolation module to physically isolate the faulty memory. Finally, it is used to determine whether the number of downgraded catastrophic faults has reached the downgraded catastrophic fault module register threshold. If not, it triggers the sending module to send memory degradation error logs to the BMC; if so, it triggers the isolation module to physically isolate the faulty memory.

[0134] The isolation module is used to physically isolate faulty memory.

[0135] The processing procedure is as follows:

[0136] When the BIOS detects a memory fault, it first distinguishes the fault type. For correctable errors (CE), no downgrading is performed; a fault message is sent to the BMC, and a fault log is recorded. This type of error will not cause a system crash. When an uncorrectable memory error (UCE) is detected, to prevent a system crash, the UCE needs to be downgraded. When a UCE is downgraded to a D-UCE fault, it is necessary to check whether the current number of D-UCEs has reached the D-UCE module register threshold A. If the threshold is not reached, no crash will occur, and a fault message is sent to the BMC, which records the fault log. If the threshold A is reached, to prevent a system crash, the faulty memory is physically isolated, which is equivalent to not configuring the faulty memory, thus preventing a crash. When a catastrophic memory error (IERR) is detected, indicating a serious memory failure, the fault is downgraded to D-IERR. The system checks if the number of D-IERR faults reaches the D-IERR module register threshold B. If it doesn't, a fault message is sent to the BMC, and a fault log is recorded. If the threshold B is reached, the memory is isolated to prevent system crashes. The D-IERR module register threshold B is less than the D-UCE module register threshold A, meaning the number of D-IERR downgrades is low. When memory generates an uncorrectable UCE or a catastrophic IERR error, the BIOS performs tiered processing, combining faulty memory isolation and fault downgrading. The primary goal is to prevent system crashes and maintain normal business operations, while simultaneously providing clear memory log information for timely maintenance.

[0140] The third setting unit is used to set the data parsing function of the machine verification library in the correctable machine check interrupt handling.

[0141] The processing unit is used to acquire correctable machine check interrupts and process memory errors through a program that handles memory degradation errors.

[0142] The information acquisition and judgment unit is used to obtain the specific faulty memory address and error type through the data parsing function of the machine verification library via the correctable machine check interrupt. If the error type is a degradation error, the sending module is triggered to send a memory degradation error log to the BMC. If the error type is a correctable memory error, the sending module is triggered to send fault information to the BMC and record the fault log. After receiving the log, the BMC obtains the memory location based on the faulty memory address and outputs a prompt message.

[0150] The instruction sending submodule is used to send instructions to retrieve memory information based on memory error information.

[0151] The instruction response submodule is used to respond to the acquisition instruction and determine the first address of a preset string that records memory information.
