It should be noted that the order of display of the embodiments of the present application only represents the order of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

[0055] Referring to Figure 1 The device testing method provided by the embodiments of the present application comprises:

[0056] S101, determining a basic input output system (BIOS) configuration file in a server, wherein the BIOS configuration file comprises configuration information supported by a target device to be tested in the server, and the target device is a device supporting a compute express link (CXL) protocol (which can also be referred to as a CXL device).

[0057] The CXL protocol supports the following three types of devices:

[0058] The first type of device is an accelerator without local memory, such as a network card.

[0059] The first type of device is integrated with an existing system through PCIe (Peripheral Component Interconnect express, which is a high-speed serial computer expansion bus standard) and directly communicates with the CPU through the CXL protocol.

[0060] The second type of device is a general-purpose accelerator, such as a graphics processing unit (GPU), an application specific integrated circuit (ASIC), and a field programmable gate array (FPGA).

[0061] Such accelerators usually have local memory of graphics double data rate (GDDR) or high bandwidth memory. The main CPU can directly access the local memory of such accelerators through the CXL protocol.

[0062] Third type of device: memory expansion board and persistent memory.

[0063] The third type of device directly communicates with the host processor and can use the CXL protocol to achieve low-latency, high-throughput data transmission.

[0064] Embodiments of the present application provide an automatic testing method for CXL devices from the perspective of server vendors, ensuring good compatibility with CXL devices before the server is delivered to users, and better meeting the application needs of users.

[0065] The BIOS configuration file in the server is determined, for example, a BIOS configuration file BIOS_Conf.txt is created under the OS of the server, which contains CXL device supported options 1-n (i.e. configuration information supported by the target device), for example: BIOS control options (type, function, etc.) supported by the CXL device.

[0066] In some embodiments, the BIOS configuration file, for example, includes:

[0067] CXL security level (Security Level) option, used to control whether the operating system (Operating System, OS) can perform read and write operations on the CXL device through the CXL memory (cxl.mem) protocol, supported options include for example: Auto (automatic), Fully Trusted (fully trusted), Untrusted (untrusted).

[0068] In the firmware layer of the server in the embodiments of the present application, the BIOS control options (such as type, function, etc.) supported by the CXL device are set in the pre-configured BIOS configuration file (for example, named BIOS_Conf.txt).

[0069] S102, modify the BIOS configuration file according to the test scenario to obtain a modified BIOS configuration file, and restart the server; wherein the modified BIOS configuration file includes: configuration information of the target device when the target device runs under the test scenario;

[0070] The test scenario, i.e., the actual application requirement of the user (not specifically limited), in the embodiment of the application, the BIOS configuration file can be modified according to the actual application requirement of the user on the CXL device, to obtain the modified BIOS configuration file.

[0071] The configuration information of the target device, for example, includes the usage mode, bandwidth, rate and the like of the CXL device.

[0072] In some embodiments, the BIOS configuration file is modified, for example:

[0073] It is assumed that the access path of the BIOS configuration file is. / scelnx / o / s bios.txt, and the file name of the BIOS configuration file is bios.txt.

[0074] The BIOS configuration file bios.txt under. / scelnx / o / s bios.txt can be exported by using a tool, and the option configuration in bios.txt is modified, for example, the control option 1 of the BIOS supported by the CXL device is modified to off, then the modified configuration information is imported by using. / scelnx / I / s bios.txt, the server is restarted, and the modified configuration information can take effect.

[0075] S103, when the server is successfully restarted, whether the configuration information in the modified BIOS configuration file takes effect is detected, a first detection result is obtained, and based on the first detection result, first test information whether the BIOS of the server supports the target device is output.

[0076] After the server is successfully restarted and enters the OS of the server, the modified BIOS configuration file BIOS_Conf_modify.txt can be exported by using a BIOS configuration modification tool, and whether the options in the BIOS_Conf_modify.txt are modified successfully is detected, for example, whether the control option 1 of the BIOS supported by the CXL device is off is checked.

[0077] The first detection result, i.e., the detection result whether the configuration information in the modified BIOS configuration file takes effect, if yes, it indicates that the BIOS of the server supports the target device, and the first test information prompts the detection result (for example, BIOS is support CXL), otherwise, it indicates that the BIOS of the server does not support the target device, and the first test information prompts the detection result (for example, BIOS is not support CXL).

[0078] In some embodiments, referring to Figure 2, the method further comprising:

[0079] S201, determining an operating system (OS) configuration file in the server, wherein the OS configuration file comprises operating system kernel version information;

[0080] In some embodiments, the OS configuration file, for example, comprises an operating system kernel (kernel) startup configuration file, and the access path of the OS configuration file is, for example, nano / etc / default / grub.

[0081] In some embodiments, the configuration of the OS can be modified by editing the content of the OS configuration file in the nano / etc / default / grub path.

[0082] S202, based on the OS configuration file, detecting whether the operating system kernel version of the server is higher than or equal to a preset version, to obtain a second detection result;

[0083] In some embodiments, based on the OS configuration file, the operating system kernel version of the server is detected, for example, comprising:

[0084] The kernel version in the OS configuration file can be queried by the instruction (uname-r) to be 5.14, but the operating system kernel version actually supporting the CXL device needs to be above 6.6, therefore, based on this detection result, it can be judged whether the OS in the current server can be used for the test of the CXL device.

[0085] The second detection result is whether the operating system kernel version of the server is higher than or equal to the preset version.

[0086] S203, based on the second detection result, outputting second test information of whether the OS of the server supports the target device, wherein the preset version is the operating system kernel version supporting the target device.

[0087] If the operating system kernel version of the server is higher than or equal to the preset version, the second test information generates corresponding prompt information (such as OS is support CXL) based on the detection result.

[0088] If the operating system kernel version of the server is lower than the preset version, the second test information generates corresponding prompt information (such as OS is not support CXL) based on the detection result.

[0089] In some embodiments, referring to Figure 3 , the method further comprising:

[0090] S301, determine an operating system (OS) profile in the server, which includes operating system kernel version information;

[0091] S302, based on the OS profile, detect whether the operating system kernel version of the server is higher than or equal to a preset version, to obtain a second detection result;

[0092] S303, detect whether the target device exists in the server, to obtain a third detection result;

[0093] For example, by executing a PCI device query instruction (lspci -tv), it is detected whether the CXL device exists in the local server.

[0094] The third detection result, that is, the detection result of whether the target CXL device exists in the server.

[0095] S304, based on the second detection result and the third detection result, output second test information of whether the OS of the server supports the target device.

[0096] That is, in the embodiment, the second test information of whether the OS of the server supports the target device is determined based on the detection result of whether the operating system kernel version of the server is higher than or equal to a preset version, and the detection result of whether the target device exists in the server. For example:

[0097] If the operating system kernel version of the server is higher than or equal to a preset version, and the target device exists in the server, the output second test information prompts that the OS of the server supports the target device (for example, OS is support CXL), otherwise, the output second test information prompts that the OS of the server does not support the target device (for example, OS is not support CXL).

[0098] In some embodiments, referring to Figure 4 , the method further includes:

[0099] S401, determine an operating system (OS) profile in the server, which includes operating system kernel version information;

[0100] S402, based on the OS profile, detect whether the operating system kernel version of the server is higher than or equal to a preset version, to obtain a second detection result;

[0101] S403, detect whether the target device exists in the server, to obtain a third detection result;

[0102] S404, when it is detected that the target device exists in the server, record address information of the target device in the server;

[0103] Record the address information of the target device in the server, for example, record the PCI device address information (such as bb:dd.f) of the CXL device in the local server.

[0104] S405, based on the second detection result and the third detection result, output the second test information of whether the OS of the server supports the target device.

[0105] In some embodiments, referring to Figure 5 , the method further comprises:

[0106] S501, determine the operating system OS configuration file in the server, which includes operating system kernel version information;

[0107] S502, based on the OS configuration file, detect whether the operating system kernel version of the server is higher than or equal to the preset version, to obtain a second detection result;

[0108] S503, detect whether the target device exists in the server, to obtain a third detection result;

[0109] S504, based on the second detection result and the third detection result, output the second test information of whether the OS of the server supports the target device.

[0110] S505, when it is detected that the target device exists in the server, record address information of the target device in the server;

[0111] S506, based on the address information of the target device in the server, detect the state information of the target device, to obtain a fourth detection result;

[0112] For example, based on the PCI device address information (such as bb:dd.f) of the CXL device in the local server, execute the PCI device state query instruction lspci-vvs bb:dd.f to detect the state of the CXL device, such as the link status and link speed of the CXL device.

[0113] S507, based on the fourth detection result, output the third test information of whether the hardware of the server supports the target device.

[0114] In some embodiments, based on the fourth detection result, output whether the hardware of the server supports the third test information of the target device, for example, including:

[0115] Based on the address information of the target CXL device in the server, the instruction (lspci|grep-i cxl) can be used to detect whether there is the following information in the state information of the target CXL device:

[0116] d7:00.0 CXL: Montage Technology Co., Ltd. Device c001 (rev 01);

[0117] If yes, it means that the hardware environment of the current server supports the target CXL device, and the third test information of the server supporting the target device is output (for example: Hardware is support CXL);

[0118] If not, it means that the hardware environment of the current server does not support the target CXL device, and the third test information of the server not supporting the target device is output (for example: Hardware is not support CXL).

[0119] The following gives an example of a specific process.

[0120] Referring to Figure 6 , the device test method provided by the embodiments of the present application comprises:

[0121] S601, determine the basic input and output system (BIOS) configuration file in the server, wherein the BIOS configuration file comprises configuration information supported by a target device to be tested in the server, and the target device is a device supporting the compute express link (CXL) protocol;

[0123] S603, when the server is restarted successfully, detect whether the configuration information in the modified BIOS configuration file is effective to obtain a first detection result, and based on the first detection result, output first test information of whether the BIOS of the server supports the target device.

[0124] S604, determine the operating system (OS) configuration file in the server, which comprises operating system kernel version information;

[0125] S605, detecting, based on the OS configuration file, whether a kernel version of an operating system of the server is higher than or equal to a preset version, to obtain a second detection result;

[0126] S606, detecting whether the target device exists in the server, to obtain a third detection result;

[0127] S607, outputting, based on the second detection result and the third detection result, second test information about whether the OS of the server supports the target device.

[0128] S608, when it is detected that the target device exists in the server, recording address information of the target device in the server;

[0129] S609, detecting, based on the address information of the target device in the server, state information of the target device, to obtain a fourth detection result;

[0130] S610, outputting, based on the fourth detection result, third test information about whether hardware of the server supports the target device.

[0131] In the embodiment, the steps S601-S603 and the steps S604-S610 can be executed in parallel or sequentially, and the specific sequence is not limited.

[0132] In order to perform different types of tests to illustrate that the target CXL device is fully supported in the server and does not affect the application of the customer's actual business system:

[0133] In some embodiments, the OS configuration file includes the following three configuration files:

[0134] a function test configuration file, a performance test configuration file, and a stress test configuration file.

[0135] In some embodiments, the BIOS configuration file includes the following three configuration files:

[0136] a function test configuration file, a performance test configuration file, and a stress test configuration file.

[0137] For the function test configuration file, for example:

[0138] For the BIOS configuration file, modify the corresponding BIOS options according to the actual function test requirements to obtain a function test configuration file (for example, bios1.txt);

[0139] For the OS configuration file, according to the actual functional test requirements, for example, modifying the parameters in the OS configuration file under the path etc / default / grub, the corresponding functional test configuration file is obtained, and the tool used may be, for example, cxlcvtest.

[0140] Regarding the performance test configuration file, the stress test configuration file, according to the above functional test configuration file, the BIOS configuration file and the OS configuration file are modified accordingly according to the actual test requirements.

[0141] That is, in the embodiment of the application, the test of the CXL device can include many types (for example: function, performance, stress), and each type of test needs to configure different BIOS and / or execute different OS instructions. The corresponding test script is written by presetting the test type, the test tool to be used, the test configuration information, the test steps (the test instructions to be executed), the pass / fail test result evaluation standard, etc. through the above configuration files, so as to realize the automation of the test configuration and execution of the CXL device. Finally, in the process of automatic test execution, the corresponding configuration information can be called according to different types of tests, such as function, performance, stress, the corresponding test steps are executed, and the corresponding pass / fail test result evaluation standard is adopted, and finally the test result (i.e. test report) is output, which ensures more comprehensive test coverage of the CXL device.

[0142] In summary, the embodiment of the application can quickly verify the CXL device at the server manufacturer end, avoid the problems of missing or incorrect modification of configuration options caused by manual modification of configuration files and testing, and thus cause test errors. That is, the embodiment of the application can more conveniently realize the test of the target device supporting the CXL protocol in the server, without manual testing by using special analyzer hardware test equipment, saving test cost and achieving better test effect. Based on the modified configuration file, the target device supporting the CXL protocol in the server can be tested in multiple types and more comprehensively according to the test scene, which can better meet the test requirements of the test scene in the actual application and make up for the blank of the lack of effective test of the CXL device at the server manufacturer end. In addition, the method provided by the embodiment of the application can also be applied to the production link of the server to verify the target CXL device in batches.

[0143] The device or apparatus provided by the embodiment of the application will be introduced below, and the explanation or illustration of the same or corresponding technical features in the above method will not be repeated.

[0144] The electronic device provided by the embodiment of the application is described below with reference to Figure 7For example, including:

[0145] The processor 700 is configured to read a program in the memory 720, and execute the following process:
