Description

Technical Field

[0001] This invention relates to the field of power-down detection, and in particular to an abnormal power-down detection method, electronic device, and storage medium. Background Technology

[0002] During SSD development, ABRUPT SHUTDOWN requires extensive and prolonged testing to ensure the stability of the SSD under abnormal power-down conditions. Currently, abnormal power-down testing often employs methods such as manual plugging and unplugging, using hot-swappable devices (quarch), or using relays to control the power button. Manual plugging and unplugging cannot meet the requirements for large-scale, long-term testing; quarch hot-swappable devices are expensive and require additional testing equipment, also failing to meet the demands of extensive testing, and the connection between the SSD and the host may negatively impact the testing process; using relays to control the power button, after testing, shows that due to the operating system and host power supply, it is highly likely to enter NORMALSHUTDOWN, making accurate testing of abnormal power-down impossible. For example, if the host is idle when the power-down detection task begins, it will send a normal power-down command and wait for firmware response. If the host is busy, and after completing higher-priority tasks, it lacks the power to send a normal power-down command, thus triggering an abnormal power-down. Summary of the Invention

[0142] Figure 6 This is an internal structural diagram of the computer device in an embodiment of the present invention; Detailed Implementation

[0143] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0144] The method provided in this application can be applied to, for example... Figure 1The flowchart of the abnormal power-down detection method shown above first configures the state of the first register to indicate entering the abnormal power-down test mode. Then, a formatting command is sent to the solid-state drive to format the file system of the solid-state drive and write the first template data into the file system. A power-down command is then sent to the solid-state drive. Next, the state of the second register is obtained to determine whether the solid-state drive has completed the power-down. Then, an attempt is made to access the file system. Finally, the second template data is obtained from the file system and the abnormal power-down detection result is generated based on the second template data and the first template data.

[0145] In one embodiment, such as Figure 2 As shown, the present invention provides a method for detecting abnormal power-down, applied to a test host, the method comprising:

[0146] S201. In response to receiving an abnormal power-down test task, configure the state of the first register to indicate entering the abnormal power-down test mode.

[0147] S202. In response to receiving a power-off command, a power-down command is sent to the solid-state drive according to the power-off command;

[0148] S203. In response to detecting that the second register status is power-down complete, the power-down operation is completed, wherein the second register status is configured by the solid-state drive based on the first register status and the power-down command to perform a pseudo-power-down action.

[0149] S204. In response to the completion of power-on, detect the solid-state drive and generate an abnormal power-down detection result for the solid-state drive.

[0150] Specifically, before performing abnormal power-down detection on the SSD, the abnormal power-down test mode can be controlled by configuring the corresponding first register A of the SSD via PCIe. For example, when the host receives the abnormal power-down detection task, writing A=1 to the first register will cause the SSD to enter the abnormal power-down test mode. Writing A=0 to the first register will cause the SSD to exit the abnormal power-down test mode without affecting its use after the test is completed.

[0151] In one embodiment, in response to receiving a power-off command, sending a power-down command to the solid-state drive according to the power-off command includes:

[0152] Send a formatting command to the solid-state drive to format the file system of the solid-state drive;

[0153] Write the first template data to the file system and send a power-down command to the solid-state drive.

[0154] Specifically, when the host receives a shutdown command from the user, it begins to perform the shutdown process. This involves first formatting the ext4 (Fourth extended filesystem) file system of the solid-state drive, then writing a pattern to the solid-state drive using the fio tool, and finally sending a power-down command to the solid-state drive.

[0155] In one embodiment, responding to the detection that the second register state is power-down complete, the power-off operation includes:

[0156] Detect the second register corresponding to the solid-state drive;

[0157] Obtain the status of the second register and determine whether the solid-state drive has completed power-down;

[0158] If so, continue with the shutdown process;

[0159] If not, then reacquire the state of the second register.

[0160] Specifically, as described above, after the test host sends a power-down command to the solid-state drive (SSD), the test host continues to acquire the status of the second register B corresponding to the SSD. If the second register indicates that the SSD has completed power-down, the test host officially completes the shutdown operation, meaning that all other components within the host have also completed power-down. However, if the second register B indicates that the SSD has not yet completed power-down, other components can be powered down first, and then the status of the second register B can be acquired again until the SSD has completed power-down, at which point the host completes the shutdown process.

[0161] In one embodiment, in response to a power-on reset, detecting the solid-state drive and generating an abnormal power-down detection result for the solid-state drive includes:

[0162] Attempt to access the file system;

[0163] If the process fails, it will be determined that the solid-state drive is not mounted and an alarm message will be sent to the user.

[0164] If successful, the second template data is obtained from the file system, and the abnormal power-down detection result is generated based on the second template data and the first template data.

[0165] Specifically, the test host can power on using a relay-controlled power switch. The SSD also powers on successfully at this time. The test host then attempts to access the SSD's file system. If access is unsuccessful or the file system is not detected, it indicates the SSD was not properly mounted after the abnormal power-down test, and an alert should be sent to the user. If the file system is successfully detected and accessed, the test host retrieves the pattern (second template data) from the file system after the abnormal power-down test and generates the final abnormal power-down detection result by comparing the two sets of data.

[0166] In one embodiment, generating the abnormal power-down detection result based on the second template data and the first template data includes:

[0167] Determine whether the first template data and the second template data are the same;

[0168] If so, a first abnormal power-down detection result is generated and sent to the user;

[0169] If not, a second abnormal power-down detection result is generated and sent to the user.

[0170] Specifically, as described above, after successfully obtaining the second template data, the original pattern (first template data) written to the file system before power-on is compared with the second template data. When the error between the two is less than, for example, within 1%, it indicates that the abnormal power-down detection of the solid-state drive is normal (first abnormal power-down detection) and is sent to the user. When the error between the two is greater than or equal to, for example, within 1%, it indicates that the abnormal power-down detection of the solid-state drive is abnormal (second abnormal power-down detection) and is sent to the user. The error coefficient can be set by the user.

[0171] In one embodiment, such as Figure 3 As shown, an abnormal power-down detection method is also provided, applied to solid-state drives, the method comprising:

[0172] S301, Receive the power-down command sent by the test host;

[0173] S302. Obtain the state of the first register, wherein the state of the first register is configured by the test host in response to receiving an abnormal power-down test task to indicate entering the abnormal power-down test mode.

[0174] S303. Perform a pseudo-power-down action based on the state of the first register and the power-down instruction;

[0175] S304. Configure the status of the second register to indicate that the solid-state drive power-down is complete.

[0176] Specifically, when receiving a power-down command from the test host, the state of the first register A is obtained. If A=1, the SSD enters an abnormal power-down test mode. In this mode, a pseudo-power-down action is performed on the received power-down command. This includes modifying the state of the corresponding second register to indicate that the power-down is complete, but not actually powering down its own file system, etc. In other words, when the host is powered off, the SSD does not perform a real power-down action, but only modifies the state of the second register.

[0177] In one embodiment, the method further includes:

[0178] S305. In response to receiving a formatting command from the test host, format the file system of the solid-state drive;

[0179] S306. Receive the first template data sent by the test host and write it into the file system.

[0180] Specifically, as mentioned above, before the host is officially shut down, a formatting command is first received from the host. According to the formatting command, the file system is formatted, that is, the original file data is cleared, and the pattern (first template data) is resent by the host.

[0181] In one embodiment, the method further includes:

[0182] S307. In response to the test data read request sent by the test host after power-on, the second template data is sent to the test host so that the test host can generate the abnormal power-off detection result based on the first template data and the second template data.

[0183] Specifically, as mentioned above, after the solid-state drive is powered on again, when a test data read request is received from the host, the pattern (second template data) in the file system after power-down and power-on is sent to the test host for comparison to generate abnormal power-down detection results.

[0184] The proposed solution has the following beneficial effects:

[0185] 1) Solved the problem that using a relay to control the switch button could not guarantee that the abnormal power-down would occur every time the device was turned off, thus improving the accuracy of abnormal power-down testing;

[0186] 2) Compared to using hot-swap testing equipment such as Quarch, it reduces testing costs and enables abnormal power-down testing of a large number of devices.

[0187] It should be understood that, although Figure 2 and Figure 3The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2 and Figure 3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but may be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0188] In one embodiment, such as Figure 4 As shown, an abnormal power-down detection device is provided, applied to a test host, the device comprising:

[0189] The first configuration module 401, in response to receiving the abnormal power-down test task, is used to configure the state of the first register to indicate entering the abnormal power-down test mode.

[0190] The instruction sending module 402, in response to receiving a power-off instruction, is used to send a power-down instruction to the solid-state drive according to the power-off instruction;
