背景技术Background technique
LCD调光需要获取后置Color sensor的数值，同时需要获取当前手机的闪光灯状态来确认色温器件的数据置信度。但是当前在Android设备中闪光灯由Cam进程控制，闪光灯状态也只有在Cam进程中轮转，并且LCD的进程和Cam的进程是天然隔离的，使用Linux提供的进程间通信方案会引入很大的隐患，所以无法通过现有的机制实现闪光灯状态的跨进程传递。LCD dimming needs to obtain the value of the rear color sensor, and at the same time, it needs to obtain the current flash status of the mobile phone to confirm the data confidence of the color temperature device. But currently the flash is controlled by the Cam process in the Android device, and the status of the flash is only rotated in the Cam process, and the LCD process and the Cam process are naturally isolated. Using the inter-process communication solution provided by Linux will introduce great hidden dangers. Therefore, the cross-process transfer of the flash state cannot be realized through the existing mechanism.

Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
以下对本申请涉及的概念进行说明。The concepts involved in this application are described below.
(1)、进程：系统中正在运行的一个应用程序，某个程序一旦运行就是一个进程，是资源分配的最小单位。(1) Process: An application program that is running in the system. Once a program is running, it is a process, which is the smallest unit of resource allocation.
(2)、内核空间：可以访问受保护的内存空间，有访问底层硬件设备的所有权限。(2) Kernel space: It can access the protected memory space and has all the permissions to access the underlying hardware devices.
其中，在内核空间，Binder驱动传递数据是通过内存来传递数据，Binder可以创建一块内存用来传递数据，传递流程如下：Among them, in the kernel space, the Binder driver transfers data through memory, and Binder can create a piece of memory to transfer data. The transfer process is as follows:
Client进程将要传递的数据放入到Client进程在内核空间对应的虚拟内存区；从Client进程在内核空间对应的虚拟内存拷贝到Binder驱动的内存，由于Binder驱动创建的内存和Server进程在内核空间对应的虚拟内存是同一内存地址，所以相当于直接拷贝到，通知Server进程读取数据；Server进程接到通知之后，就会从线程池中取出对应的线程，解析数据，并将最后的处理结果写入到Server进程在内核空间对应的虚拟内存中；将Server进程在内核空间对应的虚拟内存中的数据拷贝到Binder驱动的内存中，同样由于内存映射的原因，相当于直接拷贝到了Client进程在内核空间对应的虚拟内存中，并通知Client进程读取数据；Client进程接到通知之后，Client进程读取在内核空间对应的虚拟内存中的数据。The Client process puts the data to be transferred into the virtual memory area corresponding to the Client process in the kernel space; copies the virtual memory corresponding to the Client process in the kernel space to the memory driven by the Binder, because the memory created by the Binder driver corresponds to the Server process in the kernel space The virtual memory of the virtual memory is the same memory address, so it is equivalent to directly copying to it, and notifying the Server process to read the data; after the Server process receives the notification, it will take out the corresponding thread from the thread pool, analyze the data, and write the final processing result to into the virtual memory corresponding to the Server process in the kernel space; copy the data in the virtual memory corresponding to the Server process in the kernel space to the memory driven by Binder, also due to memory mapping, it is equivalent to directly copying the data to the Client process in the kernel space, and notify the Client process to read the data; after the Client process receives the notification, the Client process reads the data in the virtual memory corresponding to the kernel space.
(3)、用户空间：上层应用程序和Native层的运行空间，用户空间没法直接访问内核空间，需要系统调用才可以访问内核空间。(3) User space: the running space of the upper application program and the Native layer. The user space cannot directly access the kernel space, and system calls are required to access the kernel space.
其中，不同进程之间，用户空间不共享，但是内核空间是可以共享。Among them, user space is not shared between different processes, but kernel space can be shared.

当前Linux包括Android实现的进程间通信的方案中，均是采用公共部分作为桥梁实现不同进程之间的通信。In the current inter-process communication solutions implemented by Linux including Android, the public part is used as a bridge to realize the communication between different processes.
图3为相关技术中不同进程之间的数据共享方式示意图。FIG. 3 is a schematic diagram of a data sharing manner between different processes in the related art.
参照图3所示，第一进程和第二进程的相应用户空间之间存在隔离，进而导致该第一进程的用户空间与第二进程的用户空间之间不能实现直接通信，即数据不可直接共享，因此需要进行跨进程通信实现数据共享。相应的，目前可以通过以下方式进行跨进程通信：通过共享内存、管道、binder、消息队列等方式。As shown in FIG. 3 , there is isolation between the corresponding user spaces of the first process and the second process, which leads to the inability to realize direct communication between the user space of the first process and the user space of the second process, that is, data cannot be directly shared. , so cross-process communication is required to realize data sharing. Correspondingly, at present, cross-process communication can be carried out in the following ways: through shared memory, pipeline, binder, message queue, etc.
在电子设备100(例如手机)的显示屏进行显示亮度调节(LCD调光)的场景中，需要获取后置颜色传感器(Color Sensor)的数值，并且还需要获取电子设备100的闪光灯状态，并通过闪光灯状态确认色温器件的数据置信度。In the scene where the display brightness of the electronic device 100 (such as a mobile phone) is adjusted (LCD dimming), it is necessary to obtain the value of the rear color sensor (Color Sensor), and it is also necessary to obtain the flash status of the electronic device 100, and pass The flash status confirms the data confidence level of the color temperature device.

参照图4所示，电子设备100的闪关灯通过相机(Cam)进程控制，并且闪光灯状态仅在Cam进程中轮转。电子设备100显示屏的显示亮度通过显示(LCD)进程控制，然而Cam进程与LCD进程为不同的进程，且二者之间存在隔离，进而在进行LCD调光时无法通过现有的机制实现闪光灯状态的跨进程传递。Referring to FIG. 4 , the flash light of the electronic device 100 is controlled through the camera (Cam) process, and the status of the flash light is only rotated in the Cam process. The display brightness of the display screen of the electronic device 100 is controlled by the display (LCD) process, but the Cam process and the LCD process are different processes, and there is isolation between the two, so that the flash cannot be realized through the existing mechanism when LCD dimming State transfer across processes.
为克服上述技术问题，本申请实施例提供一种消息传递方法，电子设备100可以通过执行该消息传递方法，利用两个不同进程公用的硬件器件进行跨进程消息传递。具体地，在原有的设计中，某个进程的数据流和控制流都是单向的，且均为该进程的自有流程(私有流程)，换言之，数据从硬件传输到上层或者控制信号从上层传输到硬件。在本申请实施例提供的消息传递方法中，在不同进程(第一进程和第二进程)需要跨进程进行消息传递时，可以将数据流和控制流进行结合后一起传输，具体地，可以将第一进程的控制流(如某个第一进程可操控器件的状态)写入到器件驱动中，在第二进程调用器件驱动时，可以将器件驱动中保存的第一进程的控制流与第二进程的数据流一同传输给第二进程，进而实现了一种U型的消息传输，从而实现跨进程消息传递，进而一个进程可以获取到另一不同进程的状态，从而根据该不同进程的状态进行本进程的相应控制，提高电子设备进程控制的便利性。In order to overcome the above technical problems, an embodiment of the present application provides a message passing method. By executing the message passing method, the electronic device 100 can use a hardware device common to two different processes to perform cross-process message passing. Specifically, in the original design, the data flow and control flow of a certain process are unidirectional, and both are the own process (private process) of the process. In other words, data is transmitted from the hardware to the upper layer or the control signal is transmitted from the The upper layer is transferred to the hardware. In the message delivery method provided by the embodiment of the present application, when different processes (the first process and the second process) need to perform message delivery across processes, the data flow and the control flow can be combined and transmitted together. Specifically, the The control flow of the first process (such as the state of a device that can be controlled by a certain first process) is written into the device driver. When the second process calls the device driver, the control flow of the first process saved in the device driver can be combined with the second process. The data streams of the two processes are transmitted to the second process together, thereby realizing a U-shaped message transmission, thereby realizing cross-process message transmission, and then one process can obtain the state of another different process, so that according to the state of the different process The corresponding control of this process is carried out, and the convenience of electronic device process control is improved.
其中需要说明的是，相比于现有技术中上层控制下层的自上而下的进程访问同一段内存的系统调用方式，本申请实施例提供的消息传递方法时采用驱动(driver)主动保存第一进程可操控器件的状态信息，并且可以主动将存储的该第一进程可操控器件的状态信息拼接在第二进程的数据流的尾端，并随第二进程的数据流一同上报给第二进程，属于自下而上的下层直接反馈上层的消息传递方式。It should be noted that, compared with the system call method in which the upper layer controls the lower layer from top to bottom to access the same segment of memory in the prior art, the message delivery method provided by the embodiment of the present application adopts the driver (driver) to actively save the first A process can control the state information of the device, and can actively splice the stored state information of the device controllable by the first process at the end of the data stream of the second process, and report it to the second process along with the data stream of the second process. The process belongs to the bottom-up message transmission method in which the lower layer directly feeds back to the upper layer.
在本申请实施例中，实现跨进程通信的方式在于通过不同进程的公共部分进行消息传递。示例性的，可以通过Linux原生的共享内存和管道，均采用一部分的公共模块作为连接点实现，但是对于Android设备中的独立进程，该公共部分可以为kernel的器件驱动(driver)。In the embodiment of the present application, the way to realize cross-process communication is to transmit messages through common parts of different processes. Exemplarily, the native shared memory and pipelines of Linux can be implemented by using a part of the public module as a connection point, but for the independent process in the Android device, the public part can be a device driver (driver) of the kernel.
在器件driver中，通常会生成多个设备节点，并以设备节点作为内核与上层的隔离。设备节点可以包括：控制器件使能(enable)、获取器件数据(data)。In the device driver, multiple device nodes are usually generated, and the device nodes are used as the isolation between the kernel and the upper layer. The device node may include: controlling device enabling (enable) and obtaining device data (data).
同时接收参数为字符串类型，通过driver函数解析得到，其中，Kernel驱动(包含上述器件driver)通过上述设备节点接收参数，并把参数解析为实际的标志位，例如enable下发0～5，通过解析此字符串获取实际的操作意图是哪个器件的关闭打开。需要说明的是，设备节点属于双工类型，既有写入操作，即下发参数给器件驱动；例如上述enable节点，也有读取操作，即上层应用读取器件驱动反馈的数据；例如上述data节点；两种操作相反，但是上下传输的介质均为字符串。At the same time, the received parameter is a string type, which is obtained by parsing the driver function. Among them, the Kernel driver (including the above-mentioned device driver) receives the parameter through the above-mentioned device node, and parses the parameter into the actual flag bit, for example, enable sends 0 to 5, and passes Parse this string to get the actual operation intent which device is off and on. It should be noted that the device node is a duplex type, which has both write operations, that is, sending parameters to the device driver; for example, the above enable node also has read operations, that is, the upper layer application reads the data fed back by the device driver; for example, the above data Node; the two operations are opposite, but the medium for up and down transmission is a string.
在一种实施方式中，可以采用参数下发的方式向器件表明当前控制使用器件的进程的身份信息。其中，参数分为CAM、LCD和FlASH三组，分别对应三个类型。具体参数列表采用枚举类型，具体如下：In an implementation manner, the identity information of the process currently controlling the use of the device may be indicated to the device in a manner of sending parameters. Among them, the parameters are divided into three groups: CAM, LCD and FlASH, corresponding to the three types. The specific parameter list adopts the enumeration type, as follows:
在一种实施方式中，不同进程之间的通信可以结合在enable_store和data_show函数共同实现。示例性的，在电子设备100(例如手机)的显示屏进行显示亮度调节(LCD调光)的场景中，在电子设备100的上层Cam进程进行闪光灯(flash)的相关操作时，可以下发对应的参数(如闪光灯状态参数)到enable_store中，进而可以将闪光灯状态参数存入器件驱动(driver)，即，将闪光灯状态参数存入公共部分，进一步地公共部分中存储的闪光灯状态参数可以跟随LCD进程的数据流(data)一同传输给LCD进程，进而可以实现将Cam进程的闪光灯状态参数跨进程传递给LCD进程，LCD进程基于跨进程获取到的闪光灯状态参数进行显示亮度调节(LCD调光)。In one embodiment, the communication between different processes can be realized jointly by the enable_store and data_show functions. Exemplarily, in a scenario where the display brightness of the electronic device 100 (such as a mobile phone) is adjusted (LCD dimming), when the upper-layer Cam process of the electronic device 100 performs operations related to the flash (flash), the corresponding Parameters (such as flashlight status parameters) into enable_store, and then the flashlight status parameters can be stored in the device driver (driver), that is, the flashlight status parameters are stored in the public part, and the flashlight status parameters stored in the public part can follow the LCD The data stream (data) of the process is transmitted to the LCD process together, and then the flash status parameters of the Cam process can be passed to the LCD process across processes. The LCD process adjusts the display brightness based on the flash status parameters obtained across processes (LCD dimming) .
其中，电子设备100的闪光灯操作可以包括预闪和主闪，其中，预闪行为一般占用3秒，主闪行为一般占用0.5秒，控制闪光灯状态参数跟随LCD进程的data一同上报LCD进程可以使LCD进程获取到的闪光灯状态参数的实时性。Wherein, the flashlight operation of the electronic device 100 may include pre-flash and main flash, wherein, the pre-flash behavior generally takes 3 seconds, and the main flash behavior generally takes 0.5 seconds.

For the same sensorHal library (that is, the sensor Hal library), design different en_type (enablement type), and set the fields used by the process, and then realize the static library file to dynamically identify the calling process, so as to complete different processing for different processes process.
步骤602：电子设备确定当前调用传感器Hal库的进程的身份信息，基于确定结果，若为第一进程，则执行步骤603，若为第二进程，则执行步骤604。Step 602: The electronic device determines the identity information of the process currently calling the sensor Hal library. Based on the determination result, if it is the first process, perform step 603, and if it is the second process, perform step 604.
在一种实施方式中，由于针对同一个sensorHal库，设计不同的en_type，确设定了进程使用的字段，进而可以实现静态的库文件动态识别调用进程。即，可以通过sensorHal库中的en_type确定当前调用传感器Hal库的进程的身份信息。示例性的，在Cam进程和LCD进程跨进程通信，且LCD进程需要获取Cam进程中的闪光灯状态参数的场景中，可以根据en_type确定当前调用传感器Hal库的进程为Cam进程或是LCD进程，若确定当前是Cam进程调用传感器Hal库(即，Cam_enable)，则执行步骤603，若确定当前是LCD进程调用传感器Hal库(即，LCD_enable)，则执行步骤604。In one embodiment, since different en_types are designed for the same sensorHal library, the fields used by the process are definitely set, so that the static library file can dynamically identify the calling process. That is, the identity information of the process currently calling the sensorHal library can be determined through en_type in the sensorHal library. Exemplarily, in the scene where the Cam process and the LCD process communicate across processes, and the LCD process needs to obtain the flashlight status parameter in the Cam process, it can be determined according to en_type that the process currently calling the sensor Hal library is the Cam process or the LCD process, if If it is determined that the Cam process calls the sensor Hal library (ie, Cam_enable), then step 603 is performed; if it is determined that the LCD process currently calls the sensor Hal library (ie, LCD_enable), then step 604 is performed.
步骤603：电子设备将传感器Hal库设置为第一进程使用，后执行步骤605。Step 603: the electronic device sets the sensor Hal library as the first process to use, and then executes step 605.
步骤604：电子设备将传感器Hal库设置为第二进程使用，后执行步骤608。Step 604: The electronic device sets the sensor Hal library to be used by the second process, and then executes Step 608.
步骤605：电子设备确定第一进程可操控器件的工作状态，基于确定结果，若为关闭状态，则执行步骤606，若为工作状态，则执行步骤607。Step 605: The electronic device determines the working state of the device controllable by the first process, and based on the determination result, if it is in the closed state, perform step 606, and if it is in the working state, perform step 607.
步骤606：电子设备设置第一进程可操控器件对应的器件驱动的标志位置为第一属性值后，执行步骤608。Step 606: After the electronic device sets the flag position of the device driver corresponding to the first process-controllable device as the first attribute value, step 608 is executed.
在一种实施方式中，若确定第一进程可操控器件的工作状态为关闭状态，则设置器件驱动的标志位置为第一属性值可以为：若确定Cam进程可操控的闪光灯的工作状态为关闭状态，则设置器件驱动的标志位置为0，并执行步骤608。In one embodiment, if it is determined that the working state of the first process controllable device is off, then setting the flag position driven by the device to the first attribute value may be: if it is determined that the working state of the flashlight controllable by the Cam process is off state, set the flag position of the device driver to 0, and execute step 608 .
步骤607：电子设备设置第一进程可操控器件对应的器件驱动的标志位置为第二属性值后，执行步骤608。Step 607: After the electronic device sets the flag position of the device driver corresponding to the device that can be controlled by the first process as the second attribute value, step 608 is executed.
其中，Cam进程可操控的闪光灯若处于工作中，具体可以为低档位工作(low)或者高档位工作(high)。Wherein, if the flashlight controllable by the Cam process is working, specifically, it can work at a low gear (low) or at a high gear (high).
在一种实施方式中，若确定Cam进程可操控的闪光灯的工作状态为low或者high，则设置器件驱动的标志位置为1，并执行步骤608。In one embodiment, if it is determined that the working state of the flash light controllable by the Cam process is low or high, then set the flag bit driven by the device to 1, and execute step 608 .
步骤608：电子设备将进程的公共模块中存储的第一进程可操控器件的工作状态参数上报给传感器Hal库。Step 608: The electronic device reports the working state parameters of the device controllable by the first process stored in the public module of the process to the sensor Hal library.
其中，在将第一进程可操控器件的工作状态参数上报给上层进程之前，可以通过传感器Hal进行信息拦截，进行当前调用传感器Hal库的进程的身份信息的确认，进而将第一进程可操控器件的工作状态参数上报给需要该信息的进程，具体实现如步骤609至步骤611。Among them, before reporting the working state parameters of the first process-controllable device to the upper-layer process, the sensor Hal can be used to intercept information and confirm the identity information of the process that currently calls the sensor Hal library, and then the first process-controllable device The working state parameters of the information are reported to the process that needs the information, and the specific implementation is as in step 609 to step 611.
步骤609：电子设备确定当前调用传感器Hal库的进程的身份信息，若为第一进程，则执行步骤610，若为第二进程，则执行步骤611。Step 609: The electronic device determines the identity information of the process currently calling the sensor Hal library. If it is the first process, perform step 610, and if it is the second process, perform step 611.
步骤610：电子设备将第一进程对应的数据上报给第一进程。Step 610: The electronic device reports data corresponding to the first process to the first process.
在一种实施方式中，电子设备100可以仅上报色温数据给Cam进程。In an implementation manner, the electronic device 100 may only report the color temperature data to the Cam process.
步骤611：电子设备将第一进程可操控器件的工作状态参数上报给第二进程。Step 611: The electronic device reports the working state parameters of the devices controllable by the first process to the second process.
在一种实施方式中，电子设备100可以将闪光灯状态参数上报给LCD进程。In an implementation manner, the electronic device 100 may report the status parameter of the flash light to the LCD process.
在其他实施例中，采用以下两种方式实现跨进程消息传递：In other embodiments, cross-process message passing is implemented in the following two ways:
第一方式：采用metadata或者prop作为公共部分，把闪光灯的状态存储到meta或者prop中，在其他独立进程中开启循环监听来获取此公共部分的数据。The first method: use metadata or prop as the public part, store the state of the flash in meta or prop, and open loop monitoring in other independent processes to obtain the data of this public part.
第二方式：采用Android定义的binder机制实现进程间通信，在Camx的flash控制部分设计对应的binder服务，并通过系统实现的service_manager进行数据传递，在LCD中的实际控制逻辑中增加binder的接收逻辑，实现状态信息的获取。The second method: use the binder mechanism defined by Android to realize inter-process communication, design the corresponding binder service in the flash control part of Camx, and perform data transmission through the service_manager implemented by the system, and add the receiving logic of the binder to the actual control logic in the LCD , to achieve status information acquisition.
以上两替代方案可以实现进程间通信的功能，但是由于闪光灯在某些使用场景下torch的时间较短，为保证可以实时获取闪光灯的最新状态，需要提供LCD进程中的监听频率，从而导致功耗的上涨，所以综合考虑选择当前方案。The above two alternatives can realize the function of inter-process communication, but because the torch time of the flash in some usage scenarios is relatively short, in order to ensure that the latest status of the flash can be obtained in real time, it is necessary to provide the monitoring frequency in the LCD process, resulting in power consumption The rise, so comprehensive consideration to choose the current plan.
