[0003] In the related art, in some schemes, multiple logging tasks can be scheduled for writing through mutual exclusion locks, scheduling locks and spin locks, that is, each logging task needs to obtain the corresponding lock before logging, but these methods all require obtaining the corresponding lock, which results in a longer writing time for some logging tasks and cannot guarantee real-time performance; in other schemes, the atomic array method can be used to write logs for each logging task by adding a new array. Although each logging task can be completed in real time and effectively, each newly added array has a fixed maximum length, that is, the resources scheduled for each logging task are the maximum resources, which causes resource tension and waste.

[0037] In order to solve the above problems, the present disclosure provides a log processing method, device, equipment, medium and vehicle. Figures 1 to 5 The log processing method provided by the embodiment of the present disclosure is described in detail.
[0038] Figure 1 A flow chart of a log processing method provided by an embodiment of the present disclosure is shown.
[0039] In the embodiment of the present disclosure, the log processing method can be executed by an electronic device. Specifically, the electronic device can include but is not limited to a mobile terminal such as a computer device, a mobile phone, an in-vehicle device, a vehicle controller, a tablet computer, a wearable device, etc.
[0040] like Figure 1 As shown, the log processing method may include the following steps.
[0041] S110: Receive a log writing request, where the log writing request includes a content writing request and a pointer writing request.
[0042] In an embodiment of the present disclosure, the electronic device may receive a log writing request.
[0043] Optionally, the log write request may be a request to write into a log, wherein the log write request may include a content write request and a pointer write request.
[0044] Optionally, the content writing request may be for requesting log content.
[0045] Optionally, the pointer write request may be used to request writing a certain pointer.
[0046] Specifically, when a task is run through a central processing unit (CPU), it is necessary to record the relevant running log of the task. At this time, a log write request can be sent to the electronic device, and the electronic device can receive the log write request. The log write request can include a content write request and a pointer write request.
[0047] S120 . In response to the pointer write request, write a target termination pointer into a log buffer, wherein the pointer write request includes the target termination pointer.
[0048] In the embodiment of the present disclosure, the electronic device may write a target termination pointer into the log buffer in response to the pointer write request.
[0049] Optionally, the log buffer may be used to store various written log data.
[0050] Optionally, the target termination pointer may be an element for indicating a termination position, wherein the pointer write request may include the target termination pointer.
[0051] Specifically, the pointer write request may be used to request writing of a target termination pointer. In response to the pointer write request, the electronic device writes the target termination pointer included in the pointer write request into the log buffer.
[0052] S130: Use the area between the target start pointer and the target end pointer in the log buffer as the target write area.
[0053] In an embodiment of the present disclosure, the electronic device may use the area between the target start pointer and the target end pointer in the log buffer as the target write area.
[0054] Optionally, the target start pointer may be an element used to indicate a start position.
[0055] Optionally, the target writing area may be an area in the log buffer used for writing logs.
[0056] Specifically, after the electronic device writes the target end pointer into the log buffer, it can search for a pre-existing target start pointer in the log buffer, and then use the area between the target start pointer and the target end pointer as the target write area.
[0057] Figure 2A schematic diagram of a log buffer provided by an embodiment of the present disclosure is shown.
[0058] like Figure 2 As shown, in the initialization phase, when there is no log in the log buffer 201 , the existing target start pointer (start) and target end pointer (end) overlap and can be at any position in the log buffer 201 .
[0059] S140 . Writing a target log into the target write area in response to the content write request, wherein the content write request includes the target log.
[0060] In the embodiment of the present disclosure, the electronic device may write a target log into the target write area in response to the content write request.
[0061] Optionally, the target log may be a log to be written. The content writing request may include the target log.
[0062] Optionally, the target log may include a log information record and log content. The log information record may include certain information used to characterize the target log. For example, the log information record may include log length and log status. The log content may be log data generated by the task execution. The log length may include the length of the log information record and the length of the log content. The log status may be used to indicate whether the target log is valid.
[0063] Specifically, after determining the target writing area, the electronic device may respond to the content writing request and write the target log included in the content writing request into the target writing area. The target log may include log information records and log content.
[0064] Figure 3 A schematic diagram of another log buffer provided by an embodiment of the present disclosure is shown.
[0065] like Figure 3 As shown, in case 1, the electronic device can write the target end pointer (end) in the log buffer 301. At this time, the electronic device can use the area between the target start pointer (start) and the target end pointer (end) as the target write area 302. In response to the content write request, the target log can be written sequentially into the target write area 302. The target log can include log information records (H) and log content (log1).
[0066] Therefore, in the embodiment of the present disclosure, a log write request can be received, which log write request includes a content write request and a pointer write request, and then in response to the pointer write request, a target end pointer is written in the log buffer, the pointer write request includes the target end pointer, and then the area between the target start pointer and the target end pointer in the log buffer is used as the target write area, and finally in response to the content write request, a target log is written in the target write area, the content write request includes the target log, thereby, the target end pointer can be written in the log buffer according to the pointer write request, and the corresponding target write area can be determined, that is, the corresponding resource area is reasonably divided for the log buffer resources required for the log write request, thereby saving log buffer resources, and writing the target log in the target write area in real time according to the content write request, so that log writing can be performed in real time and effectively.
[0067] Optionally, S120 may specifically include: starting from the position of the target start pointer of the log buffer, determining the position of the log length away from the position of the target start pointer as the target position; and writing the target end pointer at the target position in response to the pointer write request.
[0068] In an embodiment of the present disclosure, the electronic device may start from the position of the target start pointer of the log buffer and determine a position that is the log length away from the position of the target start pointer as the target position.
[0069] Alternatively, the target location may be a location for writing a target end pointer.
[0070] Specifically, the electronic device may first determine the position of the target start pointer in the log buffer, and then determine the distance from the target start pointer to the target start pointer as the target position, that is, the distance between the target start pointer and the target position is the log length.
[0071] Furthermore, the electronic device may write the target termination pointer at the target location in response to the pointer write request.
[0072] Specifically, after the electronic device determines the target position on the log buffer, it may write the target termination pointer at the target position.
[0073] Optionally, S140 may specifically include: in response to the content write request, sequentially writing the target log starting from the target start pointer of the target write area; when the tail space of the log buffer is less than the log length, continuing to write the target log from the head space of the log buffer.
[0074] In the embodiment of the present disclosure, the electronic device may, in response to the content write request, sequentially write the target log starting from the target start pointer of the target write area.
[0075] In some embodiments, the electronic device may respond to the content write request by sequentially writing the target log starting from the target start pointer of the target write area until the target end pointer. Figure 3 , the electronic device can sequentially write the target log (log information record (H) and log content (log1)) starting from the target start pointer (start) of the target write area 302 until the target end pointer (end).
[0076] In other embodiments, if the tail space of the log buffer is smaller than the log length, the electronic device may continue to write the target log from the head space of the log buffer.
[0077] Optionally, the tail space may be free space at the tail of the log buffer.
[0078] Optionally, the header space may be an empty space at the header in the log buffer.
[0079] Specifically, when the electronic device is writing the target log, if the tail space of the log buffer is less than the log length, the target log (log information record (H) and log content (log2)) can be continued to be written from the head space of the log buffer. Figure 3 In case 1, in the log buffer 303, the corresponding target write area 304 is determined starting from the target start pointer (start). Since the free tail space of the log buffer 303 is less than the log length of the target log at this time, the tail space is insufficient to write the target log. Therefore, the corresponding target write area 304 is further divided from the free head space of the log buffer 303. When the electronic device writes the target log, it starts writing from the target start pointer (start) of the target write area 304. When the tail space is written, it continues writing from the head space until the target end pointer (end).
[0080] Optionally, S120 may specifically include: receiving multiple log write requests, determining the request reception order of multiple pointer write requests included in the multiple log write requests; and writing the multiple target termination pointers corresponding to the multiple pointer write requests into the log buffer in sequence according to the request reception order of the multiple pointer write requests.
[0081] In an embodiment of the present disclosure, the electronic device may receive multiple log writing requests and determine a request receiving order of multiple pointer writing requests included in the multiple log writing requests.
[0082] Optionally, the request receiving order may be the order in which the write requests are received.
[0083] Specifically, when multiple CPUs run tasks, they all need to send log write requests to the electronic device. The electronic device can receive multiple log write requests and determine the order of the multiple pointer write requests included in the multiple log write requests, that is, determine the order in which the multiple pointer write requests are received.
[0084] Furthermore, the electronic device may write the multiple target termination pointers corresponding to the multiple pointer write requests into the log buffer in sequence according to the request reception order of the multiple pointer write requests.
[0085] Specifically, after receiving multiple pointer write requests sent by multiple cores, the electronic device can write the multiple target termination pointers corresponding to the multiple pointer write requests into the log buffer in sequence according to the order in which the multiple pointer write requests are received. For example, when the electronic device receives multiple concurrent pointer write requests, it can determine the order in which the multiple pointer write requests are received, and first write the target termination pointer corresponding to the pointer write request that is first in the receiving order according to the order in which the requests are received, and then write the target termination pointer corresponding to the pointer write request that is second in the receiving order after the target termination pointer, and write the pointers into the log buffer in sequence. In this way, the mutually exclusive concurrent write operations of multiple pointer write requests are avoided, the reasonable writing of the log buffer is guaranteed, and the writing efficiency is improved.
[0086] Figure 4 A schematic diagram of another log buffer provided by an embodiment of the present disclosure is shown.
[0087] like Figure 4 As shown, in the log buffer 401, the electronic device can simultaneously receive two log write requests, the two log write requests being for the target log log1 and the target log log2 respectively. At this time, the electronic device can determine the request order of the pointer write requests included in the two log write requests, thereby determining the target pointer write request that is in the first place. For example, if the request order of the pointer write request for the target log log1 is in the first place, the electronic device writes the target end pointer (end) and determines the target write area as 402; for another example, if the request order of the pointer write request for the target log log2 is in the first place, the electronic device writes the target end pointer (end) and determines the target write area as 403.
[0088] Furthermore, for the remaining pointer write requests, the electronic device continues to determine the target pointer write request corresponding to the first one according to the request sequence of the pointer write requests, and performs target pointer write.
[0089] Figure 5 A schematic diagram of another log buffer provided by an embodiment of the present disclosure is shown.
[0090] like Figure 5 As shown, in the log buffer 501 , the electronic device first writes the target log (init) that is first in the request order into the target write area 502 , and then writes the target log (finish) into the target write area 503 according to the request order.
[0091] Therefore, when multiple log write requests are received, only the request that comes first in the request sequence is written, thus avoiding conflicts among the requests.
[0092] Optionally, S140 may specifically include: in response to the multiple content write requests, determining the write priorities of the multiple content write requests; and writing target logs corresponding to the multiple content write requests into the multiple target write areas according to the write priorities.
[0093] In the embodiment of the present disclosure, the electronic device may determine the write priorities of the multiple content write requests in response to the multiple content write requests.
[0094] Specifically, the electronic device may determine multiple target write areas corresponding to multiple log write requests in the log buffer, and then when writing content, the electronic device may respond to the multiple content write requests and determine the write priorities of the multiple content write requests.
[0095] Furthermore, the electronic device may write target logs corresponding to the multiple content write requests into multiple target write areas according to the write priorities.
[0096] Specifically, after determining multiple target write areas in the log buffer, the electronic device can write the corresponding target logs into the corresponding target write areas according to the write priority, in descending order of write priority. For example, for the same CPU core, when the electronic device writes to the target log log1, because the write priority of the target log log2 is higher, the CPU core will write to the target log log2 first, and then continue to write to the target log log1 after the target log log2 is written; or when writing to the target logs of two CPU cores, the CPU core that starts writing later can complete the target log writing faster because the log length of the target log is shorter.
[0097] Optionally, after S140 , the log processing method may further include: changing the log status of the target log to a valid status.
[0098] In the embodiment of the present disclosure, after writing the target log into the target writing area, the electronic device may change the log status of the target log to a valid state.
[0099] Optionally, the valid state may be used to indicate that the target log is valid.
[0100] Specifically, after writing the target log into the target writing area, the electronic device may change the log state of the target log to a valid state, for example, changing the parameter representing the log state in the target log to a valid state.
[0101] Optionally, the log processing method may further include: in response to a log reading request, detecting the log status of the target log corresponding to the log reading request; when the log status is the valid state, reading and printing the target log; and changing the log status of the target log from the valid state to the invalid state.
[0102] In an embodiment of the present disclosure, the electronic device may detect the log status of the target log corresponding to the log reading request in response to the log reading request.
[0103] Optionally, the log reading request may be a request to read a log.
[0104] Specifically, when log reading is required, the electronic device may detect the log status of the target log corresponding to the log reading request in response to the log reading request.
[0105] Furthermore, when the log status is the valid status, the electronic device can read and print the target log.
[0106] Specifically, after detecting the log status of the target log, if the log status of the target log is valid, the electronic device can read and print the target log. If the log status of the target log is not valid, the electronic device does not read and print.
[0107] Furthermore, after reading and printing the target log, the electronic device may change the log status of the target log from the valid state to the invalid state.
[0108] Optionally, the invalid state may indicate that the target log is invalid.
[0109] Therefore, by changing the log status of the target log, it can be determined whether the target log can be read and printed, or whether the target log has been printed, to prevent the target log from being mistakenly re-output when the log buffer is re-circulated.
[0110] Figure 6 A structural diagram of a log processing device provided by an embodiment of the present disclosure is shown.
[0111] In some embodiments of the present disclosure, Figure 6 The log processing device shown can be provided in an electronic device. Specifically, the electronic device can include but is not limited to a mobile terminal such as a computer device, a mobile phone, an in-vehicle device, a vehicle controller, a tablet computer, a wearable device, etc.

[0135] Figure 7 A structural diagram of a log processing device provided by an embodiment of the present disclosure is shown.
[0136] In some embodiments of the present disclosure, Figure 7 The log processing device shown can be an electronic device that the user wants to process logs. Specifically, the electronic device can include but is not limited to mobile terminals such as mobile phones, vehicle-mounted devices, vehicle controllers, tablet computers, wearable devices, smart home devices, etc.

[0138] Specifically, the processor 701 may include a central processing unit (CPU), or an application-specific integrated circuit (ASIC), or may be configured to implement one or more integrated circuits of the embodiments of the present application.
