Abstract
Description
Technical Field
[0001] The present application relates to the technical field of computer system performance debugging, and further relates to a method and system for determining time consumption based on a GPIO port, and a computer-readable storage medium. Background Art
[0002] In current performance analysis, for example, for time-consuming issues, a common approach is to use timestamp functions to perform time-consuming analysis and calculate the difference between timestamps. However, this approach may encounter limitations in practical applications. For example, some systems' timestamp functions only have millisecond (ms) accuracy, while actual analysis requirements may require further analysis down to the microsecond (us) level, leading to insufficient timestamp accuracy. Summary of the Invention
[0003] In order to solve the above technical problems, the present application provides a method, system and computer-readable storage medium for determining time consumption based on a GPIO port, which avoids the problem of insufficient accuracy of the system's timestamp function.
[0004] In the first aspect, the present application provides a method for determining the time consumption based on the GPIO port, including: setting multiple burial points on the critical path of the software operation, each burial point corresponding to a GPIO port; when the software operation passes through the first burial point, pulling up or lowering the level of the first GPIO port corresponding to the first burial point; when the software operation passes through the second burial point, pulling up or lowering the level of the second GPIO port corresponding to the second burial point; measuring and displaying the level state changes of the first GPIO port and the second GPIO port through an oscilloscope, and reading the first timestamp when the level state of the first GPIO port changes and the second timestamp when the level state of the second GPIO port changes from the oscilloscope; determining the time consumption between the first burial point and the second burial point based on the first timestamp and the second timestamp.
[0005] The above method for determining the time consumption based on the GPIO port sets multiple tracking points on the critical path of the software operation, changes the level state of the corresponding GPIO port when the software operation passes through different tracking points, and uses an oscilloscope to measure the timestamp of the level state change, so as to achieve high-precision time consumption measurement. The oscilloscope has a high time resolution, which enables it to accurately capture the moment when the GPIO port level changes, thereby providing an accurate timestamp. This high-precision time measurement capability enables this method to accurately calculate the time consumption between two tracking points, thereby avoiding the problem of insufficient accuracy of the system's timestamp function. In addition, this method can also effectively avoid the problem of interference and impact on system analysis caused by adding log printing in the method of determining the time consumption by timestamp.
[0006] In one implementation, the first burying point and the second burying point are respectively located at the starting position and the ending position of the same function, and the first GPIO port and the second GPIO port are the same GPIO port, and further includes: when the software operation passes through the first burying point, the level of the first GPIO port corresponding to the first burying point is pulled up, and when the software operation passes through the second burying point, the level of the second GPIO port corresponding to the second burying point is pulled down; or, when the software operation passes through the first burying point, the level of the first GPIO port corresponding to the first burying point is pulled down, and when the software operation passes through the second burying point, the level of the second GPIO port corresponding to the second burying point is pulled up.
[0007] The above GPIO-based timing determination method sets the start and end points of the same function as the first and second tracking points, respectively, and uses the same GPIO port to record the level changes at these two tracking points. By precisely controlling the level increase and decrease, the function's start and end points can be clearly identified, allowing the oscilloscope to accurately capture the timestamps of these two key points, thereby accurately calculating the function's execution time. This method not only solves the problem of insufficient precision of some system timestamp functions, but also avoids the interference of log printing on system analysis. The oscilloscope output provides a more intuitive view of the timing.
[0008] In one implementation, the initial level states of the first GPIO port and the second GPIO port are high level or low level.
[0009] In one implementation, when the software operation is a read or write operation, the locations of the tracking points include the file system layer, the block device layer, the driver layer, and the hardware layer.
[0010] In one implementation, the trigger conditions of the oscilloscope include rising edge triggering and falling edge triggering.
[0011] In the second aspect, the present application also provides a time-consuming determination system based on GPIO ports, including: a tracking point setting module, used to set multiple tracking points on the critical path of software operations, each tracking point corresponds to a GPIO port; a GPIO control module, used to pull up or down the level of the first GPIO port corresponding to the first tracking point when the software operation passes through the first tracking point; the GPIO control module, used to pull up or down the level of the second GPIO port corresponding to the second tracking point when the software operation passes through the second tracking point; an oscilloscope measurement module, used to measure and display the level state changes of the first GPIO port and the second GPIO port through an oscilloscope, and read the first timestamp when the level state of the first GPIO port changes and the second timestamp when the level state of the second GPIO port changes from the oscilloscope; a time-consuming calculation module, used to determine the time consumed between the first tracking point and the second tracking point based on the first timestamp and the second timestamp.
[0012] In one implementation, the first burying point and the second burying point are respectively located at the starting position and the ending position of the same function, and the first GPIO port and the second GPIO port are the same GPIO port; the GPIO control module is used to pull up the level of the first GPIO port corresponding to the first burying point when the software operation passes through the first burying point, and to pull down the level of the second GPIO port corresponding to the second burying point when the software operation passes through the second burying point; or, the GPIO control module is used to pull down the level of the first GPIO port corresponding to the first burying point when the software operation passes through the first burying point, and to pull up the level of the second GPIO port corresponding to the second burying point when the software operation passes through the second burying point.
[0013] In one implementation, the initial level states of the first GPIO port and the second GPIO port are high level or low level.
[0014] In one implementation, when the software operation is a read or write operation, the locations of the tracking points include the file system layer, the block device layer, the driver layer, and the hardware layer.
[0015] In a third aspect, the present application further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the above-mentioned methods for determining the time consumption based on the GPIO port.

[0027] Burying point is a commonly used term in software development, data analysis and performance monitoring. It refers to the pre-setting of some specific monitoring points in the software system for collecting data, analyzing performance or monitoring the operating status of the system. That is, the core of the burying point is to insert specific monitoring logic at the key position of the code so as to collect data or trigger specific behaviors at runtime. The embodiment of the present application sets multiple burying points on the critical path of the software operation through a combination of software and hardware, wherein each burying point corresponds to a GPIO (general input and output) port on the hardware. All GPIO ports are connected to an oscilloscope. When the software operation passes through a certain burying point, the level of the GPIO port corresponding to the burying point is pulled up / down to measure and display the level state change of each GPIO port through the oscilloscope, and then the corresponding time consumption is determined.
[0028] The following is explained with reference to the accompanying drawings:
[0029] Reference Attachment Figure 1 , which shows a flow chart of a method for determining the time consumption based on a GPIO port provided by an embodiment of the present application. Figure 1 As shown, including:
[0030] S100,sets multiple tracking points on the critical path of software operation, each tracking point corresponds to a GPIO port.
[0031] S110, when the software operation passes through the first buried point, the level of the first GPIO port corresponding to the first buried point is pulled up or down.
[0032] S120, when the software operation passes through the second buried point, the level of the second GPIO port corresponding to the second buried point is pulled up or down.
[0033] S130, measuring and displaying the level state changes of the first GPIO port and the second GPIO port through an oscilloscope, and reading from the oscilloscope a first timestamp when the level state of the first GPIO port changes and a second timestamp when the level state of the second GPIO port changes.
[0034] S140: Determine the time taken between the first burial point and the second burial point based on the first timestamp and the second timestamp.
[0035] Find the redundant GPIO ports on the hardware that are not used by the software, connect these GPIO ports to the oscilloscope, and configure the pins of the GPIO ports to output mode. Set multiple tracking points on the critical path of the software operation, where each tracking point corresponds to a GPIO port, and the GPIO ports corresponding to each tracking point can be the same or different. The setting of tracking points can be set according to user needs. For example, a tracking point can be set at the start and end positions of the same function to determine the time consumed within the function; for another example, a tracking point can be set at the start position of a function and a tracking point can be set at the end position of another function to determine the time consumed between the two functions; for another example, a tracking point can be set at the software operation entry and software operation exit of each software layer to determine the time consumed by the software operation at each software layer, where the software layer includes but is not limited to the file system layer, block device layer, driver layer and hardware layer, and the software operation includes but is not limited to read and write operations, data sending and receiving operations, etc.
[0036] Taking the software operation as a read and write operation as an example, and when the tracking point is set at the software layer, for example, the first tracking point is set at the read and write operation entry of the file system layer (for example, in the `vfs_read` and `vfs_write` functions), and the second tracking point is set at the read and write operation exit of the file system layer, when the read and write operation passes through the first tracking point, the level of the first GPIO port is pulled up or down (before the read and write operation passes through the first tracking point, if the level of the first GPIO port is low, the level is pulled up; if the level of the first GPIO port is high, the level is pulled down), and the level state change of the first GPIO port is measured and displayed through an oscilloscope. When the read and write operation passes through the second tracking point (or the read and write operation is completed), the level of the second GPIO port is pulled up or down (similarly, before the read and write operation passes through the second tracking point, if the level of the second GPIO port is low, the level is pulled up; if the level of the second GPIO port is high, the level is pulled down), and the level state change of the second GPIO port is measured and displayed through an oscilloscope. From the oscilloscope, read the first timestamp when the level status of the first GPIO port changes, and the second timestamp when the level status of the second GPIO port changes. Based on the first and second timestamps, the duration between the first and second tracking points can be determined, which in turn determines the duration of the read and write operations at the file system layer. The calculated duration is then saved to a log file or displayed on the debugging interface.
[0037] The first tracking point can also be set at the entry of the read and write operation of the block device layer (for example, in the `submit_bio` function), and the second tracking point is set at the exit of the read and write operation of the block device layer. When the read and write operation passes through the first tracking point, the level of the first GPIO port is pulled up or down, and the level state change of the first GPIO port is measured and displayed through an oscilloscope. When the read and write operation passes through the second tracking point, the level of the second GPIO port is pulled up or down, and the level state change of the second GPIO port is measured and displayed through an oscilloscope. The first timestamp when the level state of the first GPIO port changes and the second timestamp when the level state of the second GPIO port changes are read from the oscilloscope. Then, based on the first timestamp and the second timestamp, the time consumed between the first tracking point and the second tracking point can be determined, that is, the time consumed by the read and write operation at the block device layer can be determined. Finally, the calculated time consumption is saved to the log file or displayed on the debugging interface.
[0038] The first buried point can also be set at the read and write operation entry of the driver layer (for example,
[0039] `mmc_blk_issue_rw_rq` function), the second buried point is set at the read and write operation exit of the driver layer. When the read and write operation passes through the first buried point, the level of the first GPIO port is pulled up or down, and the level state change of the first GPIO port is measured and displayed through an oscilloscope. When the read and write operation passes through the second buried point, the level of the second GPIO port is pulled up or down, and the level state change of the second GPIO port is measured and displayed through an oscilloscope. Read the first timestamp when the level state of the first GPIO port changes and the second timestamp when the level state of the second GPIO port changes from the oscilloscope. Then, based on the first timestamp and the second timestamp, the time consumed between the first buried point and the second buried point can be determined, that is, the time consumed by the read and write operation in the driver layer can be determined. Finally, the calculated time consumption is saved to the log file or displayed on the debugging interface.
[0040] The first embedding point can also be set at the read and write operation entry of the hardware layer (for example,
[0041] `mmc_host_send_cmd` function), the second buried point is set at the read and write operation exit of the hardware layer. When the read and write operation passes through the first buried point, the level of the first GPIO port is pulled up or down, and the level state change of the first GPIO port is measured and displayed through an oscilloscope. When the read and write operation passes through the second buried point, the level of the second GPIO port is pulled up or down, and the level state change of the second GPIO port is measured and displayed through an oscilloscope. Read the first timestamp when the level state of the first GPIO port changes and the second timestamp when the level state of the second GPIO port changes from the oscilloscope. Then, based on the first timestamp and the second timestamp, the time consumed between the first buried point and the second buried point can be determined, that is, the time consumed by the read and write operation at the hardware layer can be determined. Finally, the calculated time consumption is saved to the log file or displayed on the debugging interface.
[0042] The embodiment of the present application sets multiple buried points on the critical path of the software operation, changes the level state of the corresponding GPIO port when the software operation passes through different buried points, and uses an oscilloscope to measure the timestamp of the level state change, so as to achieve high-precision time measurement. The oscilloscope has a high time resolution, which enables it to accurately capture the moment when the GPIO port level changes, thereby providing an accurate timestamp. This high-precision time measurement capability enables the method to accurately calculate the time between two buried points, thereby avoiding the problem of insufficient accuracy of the system's timestamp function. In addition, the method can also effectively avoid the problem of interference and impact on system analysis caused by adding log printing in the method of determining the time consumption by timestamp dot.
[0043] In one embodiment of the present application, the first burying point and the second burying point are respectively located at the starting position and the ending position of the same function, and the first GPIO port and the second GPIO port are the same GPIO port, and further includes: when the software operation passes through the first burying point, the level of the first GPIO port corresponding to the first burying point is pulled up, and when the software operation passes through the second burying point, the level of the second GPIO port corresponding to the second burying point is pulled down; or, when the software operation passes through the first burying point, the level of the first GPIO port corresponding to the first burying point is pulled down, and when the software operation passes through the second burying point, the level of the second GPIO port corresponding to the second burying point is pulled up.
[0044] When the user wants to determine the time consumed within a function, the first burial point and the second burial point can be set at the start and end positions of the same function respectively, or the first burial point and the second burial point can be set at the end and start positions of the same function respectively, and the first GPIO port corresponding to the first burial point and the second GPIO port corresponding to the second burial point can be the same GPIO port.
[0045] For example, consider setting the first and second buried points at the start and end of the same function, respectively. Configure the pins of the first and second GPIO ports to output mode and set their initial levels to low. When the software passes through the first buried point, the level of the first GPIO port is raised, and the oscilloscope measures and displays the change in the level of the first GPIO port. When the software passes through the second buried point, the level of the second GPIO port is lowered, and the oscilloscope measures and displays the change in the level of the second GPIO port. The oscilloscope then reads the first timestamp of the change in the level of the first GPIO port and the second timestamp of the change in the level of the second GPIO port. Based on the first and second timestamps, the time elapsed between the first and second buried points can be determined, thereby determining the time elapsed within the function.
[0046] Similarly, taking the example of setting the first and second buried points at the start and end of the same function, respectively, configure the pins of the first and second GPIO ports to output mode and set their initial levels to high. When the software operation passes through the first buried point, the level of the first GPIO port is lowered, and the oscilloscope measures and displays the change in the level of the first GPIO port. When the software operation passes through the second buried point, the level of the second GPIO port is raised, and the oscilloscope measures and displays the change in the level of the second GPIO port. The oscilloscope then reads the first timestamp of the change in the level of the first GPIO port and the second timestamp of the change in the level of the second GPIO port. Based on the first and second timestamps, the elapsed time between the first and second buried points can be determined, that is, the elapsed time within the function can be determined.
[0047] In the embodiment of the present application, the starting position and the ending position of the same function are set as the first buried point and the second buried point respectively, and the same GPIO port is used to record the level changes of the two buried points. By precisely controlling the raising and lowering of the level, the start and end of the function can be clearly identified, so that the oscilloscope can accurately capture the timestamps of these two key points, thereby accurately calculating the execution time of the function. This method can not only solve the problem of insufficient accuracy of some system timestamp functions, but also avoid the interference of log printing on system analysis, and it is more intuitive to view the time consumption through the oscilloscope output.
[0048] In one embodiment of the present application, the initial level states of the first GPIO port and the second GPIO port are high level or low level.
[0049] In one embodiment of the present application, when the software operation is a read or write operation, the locations of the embedded points include the file system layer, the block device layer, the driver layer, and the hardware layer.
[0050] In one embodiment of the present application, the trigger conditions of the oscilloscope include rising edge triggering and falling edge triggering.
