[0022] Figure 3 A structural schematic diagram of a server provided by an embodiment of the present invention. Specific implementation manners

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Currently, in the integrated testing of server systems, during the operation of the server or other tests, memory ECC (Error Correction Code) errors or memory crashes may occur probabilistically, resulting in situations such as server downtime. Therefore, during the design verification phase, stress testing tools are used to check whether the memory is working properly.

[0025] However, these tools often only provide the information stored in the memory, and it is difficult to know the specific memory slot where the error occurs, which is not conducive to the maintenance of computer systems and troubleshooting of faults.

[0026] Based on this, an abnormal memory module location method, device, and server provided by an embodiment of the present invention can quickly and accurately locate the position of the abnormal memory module, thereby solving the above technical problems.

[0027] To facilitate the understanding of this embodiment, a method for abnormal location of a memory module disclosed in an embodiment of the present invention will be introduced in detail first.

[0028] In a possible implementation manner, an embodiment of the present invention provides a method for abnormal location of a memory module, as Figure 1 shown in a flowchart of a method for abnormal location of a memory module. The method includes the following steps:

[0029] Step S102, in response to the start of a memory test operation, call a pre-configured memory test tool to test the memory configured in the current server;

[0030] Step S104, in response to the abnormal information generated during the memory test, extract the virtual address recorded in the abnormal information;

[0031] Step S106, in the pre-configured memory address mapping relationship, find the physical address corresponding to the virtual address, and based on the physical address, locate the memory slot information corresponding to the abnormal information.

[0032] In actual use, in an embodiment of the present invention, based on the memory test, after the abnormal information is monitored, the physical address corresponding to the virtual address of the abnormal information can be matched based on the memory address mapping relationship, and the physical address is directly linked to the memory stick slot. Therefore, the memory stick slot where the abnormality occurs can be located.

[0033] Furthermore, the memory address mapping relationship in the embodiment of the present invention is used to record the correspondence between the physical address, virtual address and memory slot information of each memory bar configured in the server.

[0034] Usually, the above memory address mapping relationship is obtained when the server is started. Specifically, in an embodiment of the present invention, in response to the server startup, the memory bar slot list can be confirmed based on the power-on sequence of the memory; then the behavior of BIOS mapping each memory bar in the memory bar slot list to the virtual address range is monitored to generate mapping information for each memory bar, wherein the mapping information is used to characterize the correspondence between the physical address of the memory bar and the virtual address range; then the memory address mapping relationship is generated based on the memory bar slot list and the mapping information.

[0035] Furthermore, after the server is started, it can respond, and then read the above-mentioned memory address mapping relationship, and store the memory address mapping relationship in the server's memory, so that when executing the memory bar exception locating method provided by the embodiment of the present invention, it can directly obtain and use the above-mentioned memory address mapping relationship.

[0036] In actual use, BIOS (Basic Input Output System) is a firmware that is fixed on the server motherboard. It is responsible for performing basic hardware initialization and self-test during the server startup process to ensure that the server can run normally. In addition, when the server starts, the BIOS will initialize the memory and map the physical address of each memory bank to the virtual address in the operating system.

[0037] Specifically, when the BIOS memory is initialized, the sequence number and value range of each memory module to be initialized are obtained according to the hardware memory power-on sequence. At the same time, the obtained information is transmitted to the server through the link with the operating system for storage. An example is as follows:

[0038] Memory slot 1 is initialized, and the corresponding address range is 0x00001000—0x00001999;

[0039] Memory slot 2 is initialized, and the corresponding address range is 0x00002000—0x00002999;

[0040] …

[0041] The memory slot X is initialized, and the corresponding address range is 0x0000X000 - 0x0000XXXX.

[0042] Moreover, during the subsequent operation of the server, the above mapping relationship is fixed and corresponds to the memory module slots.

[0043] Therefore, during the memory test of the server, when a memory anomaly is detected, the virtual address of the error will be recorded and an anomaly message will be generated. Then, this virtual address will be matched with the stored memory address mapping relationship to locate the memory module slot where the anomaly occurred.

[0044] For example, assume that the server has 4 memory module slots, namely Slot1, Slot2, Slot3, and Slot4. During the memory initialization phase, the BIOS maps Slot1 to the virtual address range 0x00000000 - 0x000FFFFF, maps Slot2 to the virtual address range 0x00100000 - 0x001FFFFF, and so on. If during the test, it is found that the virtual address 0x00012345 is anomalous, then, after extracting this virtual address from the anomaly message and determining based on the above memory address mapping relationship that this virtual address 0x00012345 belongs to the range 0x00000000 - 0x000FFFFF, it is possible to directly locate the memory module Slot1, so that testers can better handle the problems brought by memory failures and ensure the stability and reliability of the computer system.

[0045] Furthermore, in the embodiments of the present invention, the memory test tool is the Memtester tool.

[0046] Specifically, the Memtester tool is a powerful memory detection tool that can simulate memory load and perform tests. Its main functions and features include the following:

[0047] (1) Memory test: The Memtester tool can deeply detect whether the memory cells are working properly, identify bad blocks or hardware problems, and ensure the stability and reliability of the system.

[0048] (2) Random access mode: The Memtester tool accesses the memory in a random manner, simulating the random access mode of actual application programs to the memory, thereby making it easier to discover potential memory problems.

[0049] (3) Multiple tests: Users can specify the number of tests to run, and improve the reliability of memory problem detection through multiple tests.

[0050] (4) Test progress report: The Memtester tool can provide a test progress report, enabling users to track the progress of the test.

[0051] (5) Support for different memory sizes: Users can specify the memory size to be tested according to their needs to meet the requirements of different systems.

[0052] (6) Hardware debugging and server maintenance: Hardware engineers can use the Memtester tool to test the stability of specific memory areas, while system administrators can conduct a comprehensive check of the server memory before deployment to ensure its reliability.

[0053] Furthermore, the test items of the Memtester tool include random value test, exclusive OR comparison, subtraction, multiplication, division, AND / OR operation, etc. These test items help to comprehensively evaluate the performance and stability of the memory.

[0054] Furthermore, based on the above Memtester tool, in the embodiment of the present invention, in step S102, when calling the pre-configured memory test tool to test the memory configured in the current server, the pre-configured Memtester tool can be called to test the memory configured in the current server through the Memtester tool; if an error event occurs during the test, record the virtual address of the error event and generate exception information including the virtual address.

[0055] Furthermore, in the embodiment of the present invention, for the above exception information and the finally located memory module slot information, display them, that is, present the located memory module slot information and the exception information through the graphical user interface.

[0056] In actual use, when the Memtester tool tests the memory configured in the current server, it will first allocate a block of contiguous memory addresses in the server's memory, and then perform operations such as "random value, exclusive OR comparison, subtraction, multiplication, division, AND / OR operation" on each allocated virtual address. Once a test error or test exception occurs, when an exception is reported at this virtual address, the mapping relationship between this virtual address and the memory address can be matched, that is, find the virtual address range to which this virtual address belongs in the memory address mapping relationship, and then further determine which memory module slot this virtual address range corresponds to, and thus locate the memory module slot and generate memory module slot information including this memory module slot.

[0057] Therefore, in the embodiment of the present invention, during the memory test or other tests that require accessing the memory in the server, when a test exception occurs, it can quickly locate the memory module slot with the exception according to the software-hardware correspondence relationship recorded in the memory address mapping relationship, which helps to improve the efficiency of problem-solving.

[0058] Furthermore, the above-mentioned method for locating anomalies in the memory module provided in the embodiments of the present invention can also be integrated into a memory testing tool. For example, it can be integrated into the Memtester tool and used as an upgraded tool for the Memtester tool. For instance, when integrated into the Memtester tool, the MemtesterPlus tool is obtained. Moreover, the implementation process of the upgraded tool includes the following steps:

[0059] (1) BIOS stage:

[0060] In this stage, the BIOS initializes the memory, obtains the physical address, virtual address range, and corresponding memory module slot of each memory module, and generates a memory address mapping relationship based on this information and stores it in the system.

[0061] (2) Operating system stage:

[0062] In this stage, after the operating system starts, the upgraded tool reads the memory address mapping relationship from the system and stores it in the memory.

[0063] (3) Testing stage: The upgraded tool calls a testing tool, such as the above-mentioned Memtester tool, to perform memory testing.

[0064] If an anomaly occurs during the testing process, the upgraded tool will record the virtual address of the error and locate the memory module slot where the anomaly occurs according to the memory address mapping relationship.

[0065] (4) Result display stage: The upgraded tool displays the memory module slot information corresponding to the anomalous memory module, as well as the relevant error codes and descriptions included in the anomaly information, etc., to the user, such as a tester, through a friendly interface for the user to view. At the same time, it also helps the user to process the anomaly information in a timely manner, thereby improving the work efficiency of problem-solving.

[0066] Furthermore, the embodiments of the present invention also provide an apparatus for locating anomalies in a memory module, such as Figure 2 a schematic structural diagram of an apparatus for locating anomalies in a memory module as shown. The apparatus includes:

[0067] A calling module 20, configured to start in response to a memory testing operation and call a pre-configured memory testing tool to test the memory configured in the current server;

[0069] A positioning module 24, configured to find a physical address corresponding to the virtual address in a pre-configured memory address mapping relationship, and to locate the memory slot information corresponding to the exception information based on the physical address.

[0070] The exception positioning device for a memory module provided by an embodiment of the present invention has the same technical features as the exception positioning method for a memory module provided by the above embodiment, so it can also solve the same technical problems and achieve the same technical effects.

[0071] Furthermore, an embodiment of the present invention also provides a server, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the steps of the above method are implemented.

[0072] An embodiment of the present invention also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is run by a processor, the steps of the above method are executed.

Among them, the server includes a processor 31 and a memory 30. The memory 30 stores computer-executable instructions that can be executed by the processor 31.

The bus 32 can be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, an EISA (Extended Industry Standard Architecture) bus, etc. The bus 32 can be divided into an address bus, a data bus, a control bus, etc. For the sake of convenience of representation, Figure 3 only a bidirectional arrow is used in Figure 3 , but it does not mean that there is only one bus or one type of bus.

[0076] The processor 31 may be an integrated circuit chip with the ability to process signals. In the implementation process, the steps of the above method can be completed by the integrated logic circuit in the hardware of the processor 31 or the instructions in the form of software.
