Description

Technical Field

[0001] This invention relates to solid-state drives, and more specifically to methods, apparatus, computer equipment, and storage media for determining noise caused by SSDs. Background Technology

[0002] Windows and Linux are not real-time operating systems, meaning they cannot guarantee that requests from software will reach the hardware for processing within a specific timeframe. This isn't a problem for most hardware or tasks, but it is a challenge for audio playback. During audio playback, the audio driver must frequently and promptly transmit data from the audio buffer to the underlying system and hardware. If this process exceeds the time limit, noticeable bubbling sounds will be heard during audio playback, affecting sound quality.

[0003] When a computer equipped with a specific solid-state drive makes a popping sound, it is difficult for users or problem analysts to pinpoint the cause. Discovering and verifying the problem can only be done by listening. If the probability of it occurring is low, it is even more difficult to quantify and is hard for humans to detect.

[0004] Therefore, it is necessary to design a new method to automatically determine whether a solid-state drive will cause system audio noise. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, apparatus, computer equipment and storage medium for determining noise caused by SSDs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a method for determining noise caused by SSDs, comprising:

[0007] When the terminal is powered by battery, connect the terminal to a PCIe protocol analyzer and record the PCIe trace of music playback;

[0008] The latency of the solid-state drive responding to host commands in low-power state is determined based on the PCIe trace;

[0009] Determine whether the delay time is greater than a set threshold;

[0010] If the delay time is greater than the set threshold, it is determined that the solid-state drive will cause system audio noise problems.

[0011] The further technical solution is as follows: after determining whether the delay time is greater than the set threshold, it also includes:

[0012] If the delay time is not greater than the set threshold, it is determined that the solid-state drive will not cause system audio noise problems.

[0013] The further technical solution is as follows: determining the latency of the solid-state drive responding to host commands in low-power state each time based on the PCIe trajectory includes:

[0014] The latency of the solid-state drive responding to host commands in low-power mode was observed using the PCIe trajectory timestamp function.

[0015] The further technical solution is as follows: the delay time refers to the duration of the delay when the terminal power is unplugged, the terminal enters the power saving mode, the solid-state drive meets the command-free interval time, the solid-state drive enters the low power consumption state under the drive of the host, the host sends a command to wake up the solid-state drive, and the solid-state drive responds with a delay.

[0016] The present invention also provides a device for determining noise caused by SSDs, comprising:

[0017] The recording unit is used to connect the terminal to a PCIe protocol analyzer and record the PCIe track of music playback when the terminal is in battery-powered mode.

[0018] The delay determination unit is used to determine the delay time of the solid-state drive in responding to host commands in low-power state each time, based on the PCIe trajectory.

[0019] The judgment unit is used to determine whether the delay time is greater than a set threshold.

[0020] The first determining unit is configured to determine that the solid-state drive will cause system audio noise problems if the delay time is greater than a set threshold.

[0021] Its further technical solutions include:

[0022] The second determining unit is used to determine that the solid-state drive will not cause system audio noise problems if the delay time is not greater than a set threshold.

[0023] The further technical solution is as follows: the delay determination unit is used to observe the delay time of the solid-state drive responding to host commands each time in a low-power state according to the PCIe trajectory timestamp function.

[0024] The present invention also provides a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the above-described method.

[0025] The present invention also provides a storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0026] The beneficial effects of this invention compared with the prior art are as follows: This invention determines the delay time of the solid-state drive (SSD) in responding to host commands in low power state by using the recorded PCIe trajectory of music playback when the terminal battery is in a powered state. By using this time to determine the command response delay of the SSD in low power state, it is possible to determine whether it will cause system audio noise problems, thus realizing automatic determination of whether the SSD will cause system audio noise.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating an application scenario of the method for determining noise caused by SSDs provided in this embodiment of the invention. Figure 2 This is a schematic flowchart illustrating a method for determining SSD-induced noise according to an embodiment of the present invention. This method is applied in a terminal that interacts with a solid-state drive (SSD). By measuring the command response latency of the SSD in a low-power state, it can accurately and proactively determine whether an SSD might cause system audio noise problems.

[0039] Specifically, the test was conducted using a terminal combined with a PCIe protocol analyzer, with a Windows or Linux operating system as the software environment and a PCIe interface solid-state drive as the solid-state drive.

[0040] Figure 2 This is a flowchart illustrating the method for determining noise caused by an SSD according to an embodiment of the present invention. Figure 2 As shown, the method includes the following steps S110 to S150.

[0041] S110. When the terminal is powered by battery, connect the terminal to a PCIe protocol analyzer and record the PCIe trace of music playback.

[0042] In this embodiment, the PCIe (Peripheral Component Interconnect Express) track refers to the track recorded after the terminal is connected to the PCIe protocol analyzer and played for a period of time.

[0043] S120. Determine the latency of the solid-state drive responding to host commands each time in a low-power state based on the PCIe trace.

[0044] In this embodiment, the delay time refers to the duration of the delay when the terminal's power is turned off, the terminal enters power-saving mode, the solid-state drive meets the command-free interval time, the solid-state drive enters a low-power state under the host's drive, the host sends a command to wake up the solid-state drive, and the solid-state drive responds.

[0045] Specifically, the latency of the solid-state drive responding to host commands each time in a low-power state is observed using the PCIe trajectory timestamp function.

[0046] Please see Figure 3 The solid-state drive (SSD) command delay is as follows: When the terminal's power is unplugged and put into power-saving mode, the host will put the SSD into a low-power state as long as the "no command interval" is met. After that, the host will send a command to wake up the SSD or other commands, and the SSD will have a response delay.

[0047] S130. Determine whether the delay time is greater than a set threshold.

[0048] In this embodiment, during the process of using a computer with bubbling sounds, it was found that the solid-state drive (SSD) may frequently enter a low-power state during audio playback. Further investigation using PCIe trace revealed that the SSD producing bubbling sounds had a longer latency in responding to host commands in the low-power state than a normal SSD, and the longer the latency, the more pronounced the noise problem.

[0049] Taking Table 1 as an example, if the command response latency of a certain solid-state drive in low power mode is greater than x milliseconds, it is easy to cause system audio noise problems.

[0050] Table 1. Noise Test

[0051] Different solid-state drives Command response latency in low power mode Noise test #1 Approximately x milliseconds Cannot hear noise #2 Approximately y milliseconds (y is greater than x) Occasionally hear noise #3 Approximately z milliseconds (z is greater than y) Frequent noise #3 shortened from z to x milliseconds Cannot hear noise

[0052] As shown in Table 1, by measuring the command response latency of the solid-state drive (SSD) in a low-power state, it is possible to determine in advance and accurately whether an SSD might cause system audio noise problems.

[0053] S140. If the delay time is greater than the set threshold, it is determined that the solid-state drive will cause system audio noise problems.

[0054] S150. If the delay time is not greater than the set threshold, it is determined that the solid-state drive will not cause system audio noise problems.

[0055] In this embodiment, if the command response delay is greater than x milliseconds, it is considered that the solid-state drive will cause system audio noise problems, as shown in Table 2.

[0056] Table 2. Test Results

[0057] Solid State Drive Response Latency Is there audio noise? ≤x ms Test passed, no risk of audio noise. >x ms Test failure will cause system audio noise.

[0058] By measuring the command response latency of a solid-state drive (SSD) in a low-power state using a PCIe protocol analyzer, it can be determined whether it will cause system audio noise problems, without having to rely on human hearing.

[0059] The aforementioned method for determining SSD noise involves recording the PCIe traces of music playback while the terminal is powered by battery. This allows for the determination of the SSD's response time to host commands in low-power mode. By using this time to determine the SSD's command response latency in low-power mode, it is possible to determine whether it will cause system audio noise. This method enables automatic determination of whether an SSD will cause system audio noise.
