Figure 1 Among them, the XR device runs the XR system, which is an operating system that is customized and improved based on the characteristics of the XR device.

The user may input / output voice information through the speaker 1700 and the microphone 1800.

[0048] Despite Figure 1 In the figure, multiple devices are shown for the XR device 1000, but the present application may only involve some of the devices, for example, the XR device 1000 only involves the memory 1200, the processor 1100 and the display device 1500.

[0049] In the embodiment of the present application, the memory 1200 of the XR device 1000 is used to store instructions, which are used to control the processor 1100 to execute the memory management method based on the XR system provided in the embodiment of the present application.

[0050] In the above description, the technician can design instructions according to the scheme disclosed in this application. How instructions control the processor to operate is well known in the art, so it will not be described in detail here.

[0051] It should be noted that for XR devices, applications therein often consume a large amount of memory when running, including graphics memory and other resources, and this high demand can easily cause XR devices to fail due to insufficient memory capacity. In this regard, the present application provides a memory management method for XR devices, namely, a memory management method based on an XR system.

[0052] This application provides a memory management method based on an XR system, which is applied to Figure 1 XR device shown.

[0053] like Figure 2 As shown, the memory management method based on the XR system provided in the present application includes the following steps S2100 and S2200.

[0054] Step S2100, for the XR system, obtain the current memory water level mark value.

[0055] In one embodiment of the present application, when an XR system improved based on an Android operating system is running in an XR device, the current memory water level mark value can be obtained by calling the lmkd process in the XR device.

[0056] The lmkd process is a daemon process in the Android operating system, and its full name is Low Memory Killer Daemon, which is translated into Chinese as "Low Memory Killer Daemon". Its main function is to monitor the memory status of the Android operating system.

[0057] In one embodiment of the present application, the specific implementation of the above step S2100 may be: obtaining the current memory water level mark value in real time.

[0058] In another embodiment of the present application, the specific implementation of the above step S2100 can also be: according to the set time interval, obtain the current memory water level mark value. The set time interval can be set based on experience. For example, the set time interval is 5 minutes.

[0059] Step S2200, when the current memory water level mark value is less than the preset memory water level mark value, trigger a memory dump operation to obtain an operation result.

[0060] The preset memory water level mark value is the minimum memory water level mark value at which the operating system may have a running failure due to insufficient memory capacity. The operating system running failure may be, for example, a critical process being killed.

[0061] Memory dump is an important diagnostic tool that records the complete state of the operating system's current memory, including running processes, allocated memory areas, memory fragmentation, etc. The memory dump operation is the operation of running a memory dump.

[0062] In this embodiment, for the XR system, when the current memory water level mark value is less than the preset memory water level mark value, it means that the XR system has the possibility of operating failure due to too small memory capacity, and the memory dump operation is triggered at this time to obtain the operation result. In this way, it can be achieved that when the XR system has the possibility of operating failure due to too small memory capacity, the memory dump operation is triggered. Compared with the traditional technology that the memory dump operation will only be triggered after the operating system has a problem, the memory dump operation is triggered in advance. That is, the present application provides a new triggering mechanism for the memory dump operation for the XR system, which avoids the problem of time lag in triggering the memory dump operation. On the basis that the operating system operation failure occurs very quickly, the operation result obtained based on the above step S2200 can accurately reflect the actual memory state when the operating system failure occurs, thereby helping developers to effectively troubleshoot and analyze problems in the operating system.

[0063] Corresponding to the above step S2200, when the current memory water level mark value is greater than or equal to the preset memory water level mark value, it means that the memory capacity is sufficient and the operation of the XR system is not affected. At this time, the above step S2100 is repeated.

[0064] In addition, in one embodiment of the present application, the specific implementation of the above steps S2100 and S2200 in the program can be: the lmkd process obtains the current memory water level mark value; the lmkd process reports the current memory water level mark value to the XR system; when the XR system determines that the current memory water level mark value is less than the preset memory water level mark value, the XR system reports to the AMS (Android Memory System) process that the current memory water level mark value is less than the preset memory water level mark value; the AMS process triggers a memory dump operation based on the current memory water level mark value reported by the XR system being less than the preset memory water level mark value.

[0065] The present application provides a memory management method based on an XR system, the method comprising: for the XR system, obtaining the current memory water level mark value; when the current memory water level mark value is less than the preset memory water level mark value, triggering a memory dump operation to obtain an operation result. In this embodiment, for the XR system, when the current memory water level mark value is less than the preset memory water level mark value, it means that the XR system has the possibility of an operation failure due to too small a memory capacity, and at this time, a memory dump operation is triggered to obtain an operation result. In this way, it is possible to trigger a memory dump operation when there is a possibility of an operation failure in the XR system due to too small a memory capacity. Compared with the traditional technology in which the memory dump operation is only triggered after a problem occurs in the operating system, the memory dump operation is triggered in advance. That is, the present application provides a new triggering mechanism for a memory dump operation for the XR system, which avoids the problem of time lag in triggering the memory dump operation.

[0066] In one embodiment of the present application, after the operation result is obtained based on the above step S2200, the operation result can be written into a dump file.

[0067] In another embodiment of the present application, in order to facilitate quick viewing by developers, the memory management method based on the XR system provided by the present application further includes the following step S2300 after the above step S2200.

[0068] Step S2300, write the operation result into the log.

[0069] In this embodiment, the operation results are written into the log for quick viewing by the developer.

[0070] In one embodiment of the present application, the specific implementation of the above step S2300 in the program may be: instructing to run a preset log code, wherein the log write object in the log code is the operation result obtained based on the above step S2200.

[0071] In one embodiment of the present application, the above step S2200 can be specifically implemented through the following steps S2210 and S2211.

[0072] Step S2210, obtaining memory dump parameter requirements.

[0073] Step S2211, when the current memory water level mark value is less than the preset memory water level mark value, trigger a memory dump operation according to the memory dump parameter requirement to obtain an operation result.

[0074] In this embodiment, the memory dump parameter requirement is used to describe the requirements for the parameters included in the finally generated operation result. In one embodiment of the present application, the memory dump parameter requirement in the above step S2210 is written into the XR device by the developer according to the requirements.

[0075] In another embodiment of the present application, the specific implementation of the above step S2210 can also be: obtaining a second input for the second setting input interface; and obtaining a memory dump parameter requirement in response to the second input. In this embodiment, according to the developer's own needs, the memory dump parameter that meets the developer's own needs can be input into the second input interface. This meets the developer's personalized needs.

[0076] After the memory dump parameter requirements are obtained based on the above step S2210, when the current memory water level mark value is less than the preset memory water level mark value, the operation result obtained after triggering the memory dump operation according to the memory dump parameter requirements includes the memory dump parameters required in the memory dump parameter requirements.

[0077] In one embodiment of the present application, the memory dump parameter requirements include: obtaining ION memory status parameters, wherein the ION memory status parameters include: at least one of the total amount of ION memory, allocation status, current status, and distribution in the operating system.

[0078] In this embodiment, the operation result obtained after executing the above step S2211 includes at least one of the total amount, allocation, current state and distribution of ION memory in the operating system. In this way, the memory management method based on the XR system provided by the present application can realize detailed recording of ION memory, and can provide developers with a comprehensive understanding of ION memory usage.

[0079] In one embodiment of the present application, the memory dump parameter requirement includes: obtaining a buddyinfo data structure. In this regard, the method provided by the present application also includes the following step S2400.

[0080] Step S2400: determining the memory fragmentation state according to the buddyinfo data structure.

[0081] In this embodiment, when the memory dump parameter requirement includes: obtaining a buddyinfo data structure, the memory dump operation may include: for the memory of the XR system, calling a buddy system algorithm for processing to obtain a buddyinfo data structure.

[0082] Among them, the buddyinfo data structure includes the following contents: Node information: the memory is divided into multiple nodes, each node consists of a group of CPUs and local memory. The buddyinfo data structure will display the information of each node, such as Node0, Node1, etc.; Zone information: the memory under each node can be divided into multiple zones, such as DMA, Normal, HighMem, etc. These zones have different characteristics and uses. For example, the DMA zone is usually used for DMA devices, the Normal zone is used for ordinary memory allocation, and the HighMem zone is used for high-end memory; Page information: the memory page is the smallest unit of physical memory, also called a page frame; Free memory block information: for each zone, the buddyinfo data structure will display the number of free memory blocks of different orders, which indicates the size and number of available continuous memory blocks in the zone in the current system.

[0083] Based on the above, we can see that the buddyinfo data structure can reflect the complete information of memory fragmentation. Therefore, the memory fragmentation status can be determined based on the buddyinfo data structure. This helps to accurately diagnose memory problems and optimize memory management.

[0084] In one embodiment of the present application, the above-mentioned step S2400 can be implemented according to at least one of the following steps S2410, S2411 and S2412.

[0085] Step S2410: determine the total free memory according to the buddyinfo data structure.

[0086] In this embodiment, the memory fragmentation state is represented by the total free memory. And the specific implementation of the above step S2410 can be: extracting the free memory block information from the buddyinfo data structure, and calculating the total free memory based on the free memory block information.

[0087] Step S2411, determining the total free memory and the maximum continuous free memory according to the buddyinfo data structure, and determining that the memory is externally fragmented when the maximum continuous free memory is smaller than the total free memory.

[0088] In this embodiment, the memory fragmentation state is represented by whether there is external fragmentation. Also, the method for determining the total free memory in the above step S2411 is the same as the specific implementation of the above step S2410, which will not be repeated here. The method for determining the maximum continuous free memory in the above step S2411 can be: extracting the free memory block information from the buddyinfo data structure, and finding the maximum continuous free memory based on the free memory block information.

[0089] After determining the total free memory and the maximum continuous free memory, determine the size relationship between the two. If the maximum continuous free memory is smaller than the total free memory, determine that the memory has external fragmentation. If the maximum continuous free memory is equal to the total free memory, determine that the memory does not have external fragmentation.

[0090] Step S2412: determining the total free memory and the maximum continuous free memory according to the buddyinfo data structure, and determining a fragmentation index according to the total free memory and the maximum continuous free memory.

[0091] In this embodiment, the memory fragmentation state is represented by a fragmentation index. Also, the method for determining the total free memory and the maximum continuous free memory in the above step S2412 is the same as the specific implementation of the above step S2411, which will not be repeated here.

[0092] In one embodiment of the present application, the fragmentation index in the above step S2412 may be determined according to the following formula.

[0093] Fragmentation index = (total free memory - maximum continuous free memory) / total free memory.

[0094] In one embodiment of the present application, the memory management method based on the XR system provided by the present application further includes the following steps S2220 and S2221 before the above-mentioned step S2200.

[0095] Step S2220: Acquire a first input for a first setting input interface.

[0096] Step S2221, in response to the first input, determining a preset memory water level mark value.

[0097] In this embodiment, the first setting input interface is used for the developer to input the preset memory water level mark value. The data input by the developer in the first setting input interface is identified as the first input. Further, the data corresponding to the first input is recorded as the preset memory water level mark value.

[0098] Among them, the developer can determine the preset memory water level mark value based on experience or experiments.

[0099] Based on the above steps S2220 and S2221, the present application provides a method for determining a preset memory water level mark value.

[0100] In another embodiment of the present application, the memory management method based on the XR system provided by the present application further includes the following steps S2230 and S2231 before the above-mentioned step S2200.

[0101] Step S2230, obtaining the standard memory capacity value.

[0102] Step S2231, determining a preset memory water level mark value according to the standard memory capacity value.

[0103] In the embodiment of the present application, the standard memory capacity value is the maximum available memory capacity value of the XR device, which can be determined according to the parameters of the XR device.

[0104] In one embodiment of the present application, the specific implementation of the above step S2231 may be: using a preset percentage of the standard memory capacity value as a preset memory water level mark value, wherein the preset percentage may be specifically 20%.
