Fig. 4 is a flowchart illustrating a hardware resource control method according to an embodiment of the present application.

As shown in fig. 4, the above hardware resource control method may include:

Step S10: a first operation of a user is received.

It should be noted that the first operation is a power-on operation, for example, the user clicks the power key to open the screen, and the power-on operation may be performed in other manners, which is not limited in this embodiment.

Step S20: and responding to the first operation, and starting a display process.

In this embodiment, the display process is a display process of a display screen, for example, after a user clicks a power key to open the screen, the display process of the display screen is started.

Step S30: a second operation of a user for a camera application of the electronic device is received.

In this embodiment, the second operation is an operation of starting the camera application, which may be a touch operation of opening the camera application, for example, the user clicks a camera icon on a desktop of the mobile phone, or may open the camera application in other manners, which is not limited in this embodiment.

Step S40: and responding to the second operation, and starting a camera process.

Step S50: and controlling the color temperature sensor to be electrified or powered off based on a call request of the display process to the color temperature sensor of the electronic equipment and a call request of the camera process to the color temperature sensor, wherein the value of the first flag bit is used for indicating the number of processes which have currently called the color temperature sensor.

It can be understood that, the call request of the display process to the color temperature sensor of the electronic device may be a request to power up the color temperature sensor, or may be a request to power down the color temperature sensor, and similarly, the call request of the camera process to the color temperature sensor may be a request to power up the color temperature sensor, or may be a request to power down the color temperature sensor, for example, a request lcd_enable of the display process to power up the color temperature sensor of the electronic device, a request lcd_disable of the display process to power down the color temperature sensor of the electronic device, a request cam_enable of the camera process to power up the color temperature sensor of the electronic device, a value of a first flag bit is used to indicate that the color temperature sensor is currently invoked, for example, when the first flag bit is 0, indicates that there is no application process to invoke the color temperature sensor, when the first flag bit is 1, the display process invokes the color temperature sensor is currently invoked, and when the first flag bit is 1, the first flag bit is invoked by 2, and so on indicates that the color temperature sensor is invoked by analogy.

Step S60: and after the color temperature sensor is controlled to be electrified or powered off, updating the value of the first zone bit.

It should be noted that, in a general case, no matter whether there is any other application process currently using the color temperature sensor, if there is any application process currently using the color temperature sensor to power down, power down processing is performed on the color temperature sensor, so that other application processes cannot use the color temperature sensor, where an operation state of the color temperature sensor may be power up or power down processing of the color temperature sensor, and other types of processing may also be included.

The application determines whether other application processes currently use the color temperature sensor through the number of application processes, and when the number of application processes is larger than 1, the color temperature sensor is not powered down by the other application processes currently use the color temperature sensor, and when the number of application processes is equal to 1, the color temperature sensor is powered down by the other application processes currently not used by the color temperature sensor, so that the problem that the color temperature sensor cannot be used by the other application processes due to the power down condition is avoided.

In one possible implementation manner, when the color temperature sensor is powered on, if the number of application processes is greater than or equal to 1, it is indicated that the current application process is using the color temperature sensor, and if the number of application processes is less than 1, it is indicated that the current application process is not using the color temperature sensor, and then the color temperature sensor can be powered on, so that the power on process is not needed to be continued when the color temperature sensor is already using the application process, and the power on process is performed again when the application process is not using the color temperature sensor, thereby improving the processing efficiency of the system.

In the specific implementation, when the color_enable node receives an enable message, firstly judging the value of a flag bit, if the value is 0, indicating that the color temperature sensor is not used in a process, and the color temperature sensor is in a power-down state, so that the color temperature sensor is powered on later, and the value of the flag bit is +1 after the power-on is successful; if the value is not 0, the color temperature sensor is used by one or more processes, the color temperature sensor is in a power-on state, then power-on operation is not performed again, and only the bit value of +1 is used for realizing the real-time updating of the first bit, so that the flexible control of the temperature sensor is improved.

In this embodiment, by receiving a first operation of a user; in response to the first operation, starting a display process; receiving a second operation of a user for a camera application of the electronic device; responding to the second operation, and starting a camera process; based on a call request of the display process to a color temperature sensor of the electronic equipment, a call request of the camera process to the color temperature sensor, and a first flag bit for controlling the power-on or power-off of the color temperature sensor, wherein the value of the first flag bit is used for indicating the number of processes which have currently called the color temperature sensor; after the color temperature sensor is controlled to be electrified or powered off, the value of the first zone bit is updated, so that whether an application process using the color temperature sensor exists currently or not is determined according to the first zone bit, and the power off is not directly carried out when the application process using the color temperature sensor exists, so that other application processes are ensured to normally use the color temperature sensor.

Fig. 5 is a flowchart of a hardware resource control method according to another embodiment of the present application, as shown in fig. 5, where the above hardware resource control method is based on the first embodiment, and the step S50 includes:

Step S501 is to acquire a type of a call request of the display process or the camera process to the color temperature sensor of the electronic device.

It should be noted that, the type of the call request for the color temperature sensor of the electronic device may be a cam_enable, lcd_enable, flash_enable, or cam_disable, or lcd_ disable, flash _disable request, that is, the color temperature sensor power-up request and the color temperature sensor power-down request, and may further include other types of call request types for the color temperature sensor, which is not limited in this embodiment.

In this embodiment, a voting control logic is used to determine whether the color temperature sensor executes a power-on or power-off process, where the voting control logic is implemented in an enable_store function, and the main logic is as follows: 1. according to the received parameters cam_enable and LCD_enable, confirming which process is currently using the device, and storing information into data; 2. defining global int type variable, recording the number of processes of the currently used device, and when receiving an enable request, judging whether a process uses the device, if so, only counting by +1, and not actually performing the current flow; when no process is used currently, the power-on flow is called after the count of +1, and when the power-on fails, the count is carried out by-1, and a result is returned; 3. when receiving a disable request, judging how many processes are using the device, if the count is 1, namely, only the current process is in use, preferentially counting-1, then performing actual power-down operation, and if the power-down fails, counting +1 again and returning a result; if the number is greater than 1, the count is only-1, and the actual power-down function is not called.

In this embodiment, on the basis of the number of application processes, a current call request is further determined, whether the color temperature sensor performs a power-on or power-off process is determined according to the current call request, when the current call request is a cam_enable or lcd_enable request, it is determined that the current color temperature sensor is required to perform the power-on process, when the current call request is a cam_disable or lcd_disable request, it is determined that the current color temperature sensor is required to perform the power-off process, and according to the current call request and the number of application processes indicated by the flag bit, the color temperature sensor is controlled to perform the power-on or power-off process, thereby ensuring flexible call to the color temperature sensor.

Step S502, when the type of the call request of the display process or the camera process to the color temperature sensor is a type of powering on the color temperature sensor, and the first flag bit is 0, controlling the color temperature sensor to be powered on.

It should be noted that, when the type of the call request of the display process or the camera process to the color temperature sensor is a power-on type of the color temperature sensor, and the first flag bit is 0, it is indicated that no application process currently uses the color temperature sensor, in this case, since the current application process is indicated to use the color temperature sensor and no other application process uses the color temperature sensor when the enable request is received, the number of application processes currently used to use the color temperature sensor is increased based on the number of application processes counted originally, that is, the number of application processes is increased, and the color temperature sensor is controlled to execute a power-up process, for example, when the first flag bit is 0, the enable request is received, the first flag bit +1 is obtained, the first flag bit is 1, and the color temperature sensor is controlled to execute the power-up process.

In step S503, when the type of the call request of the display process or the camera process to the color temperature sensor is the type of powering on the color temperature sensor, and the first flag bit is not 0, the power-on state of the color temperature sensor is maintained, and the power-on process is not executed any more.

It should be noted that, when the type of the call request of the display process or the camera process to the color temperature sensor is a power-on type of the color temperature sensor, and the first flag bit is greater than 0, it is indicated that the current existing application process is using the color temperature sensor, in this case, since the current application process needs to use the color temperature sensor when the current application process receives the enable request, the number of application processes is increased on the basis of the number of application processes counted originally, that is, the number of application processes is increased, and the color temperature sensor is controlled to keep a power-on state, for example, when the first flag bit is 1, the first flag bit +1 is received, so that the first flag bit is 2, and the color temperature sensor is controlled to keep a power-on state, so that the current process is not actually performed, the repeated power-on operation is avoided, and the efficiency of system processing is improved.

In one possible implementation manner, after the step S501, the method further includes:

and when the type of the calling request of the display process or the camera process to the color temperature sensor is the type of powering down the color temperature sensor, and the first flag bit is 1, controlling the color temperature sensor to be powered down.

It can be understood that when the type of the call request of the display process or the camera process to the color temperature sensor is a power-down type, i.e. disable type, of the color temperature sensor, and the first flag bit is equal to 1, it indicates that only the current application process is using the color temperature sensor, in this case, since the current application process is controlled to execute the power-down process by the color temperature sensor when the disable request is received, it is indicated that the current application process is subtracting the number of application processes that are currently using the color temperature sensor on the basis of the number of application processes counted originally, i.e. the number of application processes is reduced, and the color temperature sensor is controlled to execute the power-down process, for example, when the first flag bit is 1, the disable request is received, the first flag bit-1 is obtained, and the color temperature sensor is controlled to execute the power-down process, and since the current application process is determined to be using the color temperature sensor through the current call request and the number of application processes, the current application process is prevented from affecting the use of other applications when executing the power-down process, and the other applications can be prevented from executing the power-down process, thereby using the color temperature sensor normally.

It should be noted that, when the type of the call request of the display process or the camera process to the color temperature sensor is the down type, that is, the disable type, and the first flag bit is an integer greater than 1, it is indicated that there are other application processes currently using the color temperature sensor, in this case, since the current application process controls the color temperature sensor to execute the down current process to affect the normal use of other application processes when receiving the disable request, it is indicated that the current application process is controlled by the current application process to execute the down current process, so that the current application process to be used currently is subtracted from the number of application processes counted originally, that is, the number of application processes is reduced, and the color temperature sensor is controlled to keep the power-on state, and the actual power-on function is not called, for example, when the first flag bit is 3, the disable request is received, the first flag bit-1 is obtained, and the actual power-on function is not called, and since the current application process is determined whether there is a used device or not through the current application process number is executed, the current application process is ensured to be used when executing the down current application process, thereby other applications can be prevented from affecting the normal use of the color temperature sensor.

In one possible implementation manner, the step S60 includes:

after the color temperature sensor is controlled to be electrified, adding 1 to the value of the first zone bit; after the color temperature sensor is controlled to be powered down, the value of the first flag bit is reduced by 1, for example, when the first flag bit is 1, the first flag bit +1 is obtained by receiving an enable request, when the first flag bit is 3, the first flag bit-1 is obtained by receiving a disable request, and the first flag bit is 2.

In one possible implementation manner, after the updating the value of the first flag bit, the method further includes:

monitoring a first use state of the color temperature sensor after controlling the color temperature sensor to be powered on; when the first use state of the color temperature sensor is a power-on abnormal state, determining that the color temperature sensor fails to be powered on; and subtracting 1 from the first zone bit after the power-on failure of the color temperature sensor.

In this embodiment, the power failure may determine whether the color temperature sensor is power failure by monitoring a communication state with the color temperature sensor and an operation state of the color temperature sensor, when the power failure occurs, the number of application processes of the color temperature sensor is reduced, and a power failure result is returned, for example, when the first flag bit is 0, the first flag bit +1 is received when an enable request is received, the updated first number is 1, and when the power failure occurs, the updated flag bit-1 is updated again to obtain the updated first number 0, so that real-time update of the number of application processes is ensured, thereby improving accuracy of hardware resource control.

In one possible implementation manner, after the updating the value of the first flag bit, the method further includes: monitoring a second use state of the color temperature sensor after controlling the color temperature sensor to be powered down; when the second use state of the color temperature sensor is detected to be a power-down abnormal state, determining that the color temperature sensor fails to power down; and after the color temperature sensor fails to be powered down, adding 1 to the first flag bit.

In this embodiment, the power-down failure may determine whether the color temperature sensor fails to power down by monitoring a communication state with the color temperature sensor and an operation state of the color temperature sensor, when the power-down fails, increase the number of application processes of the color temperature sensor, ensure the number of application processes, and return a power-down failure result, for example, when the first flag bit is 1, the first flag bit-1 is obtained after receiving the disable request, and when the power-down fails, the first flag bit +1 is obtained after being updated again is 1, so as to ensure real-time update of the number of application processes, thereby improving accuracy of hardware resource control.

In one possible implementation, the method further includes: acquiring a call request of each application process to the color temperature sensor; matching the calling request of each application process to the color temperature sensor with a preset request parameter list, wherein the preset notification parameter list comprises all application process information capable of calling the color temperature sensor; and determining the number of processes which are currently called for the color temperature sensor according to the matching result.

In this embodiment, two processes or more processes control and use devices simultaneously, and to coordinate and control the two processes or more processes, a common part of an independent process needs to be found, and in this scenario, the most suitable common part is a device driver.

In the device driver, a plurality of device nodes are usually generated, and the device nodes are used as isolation between the kernel and the upper layer. These nodes will typically include enable representation to control device enablement, data representation to retrieve device data, and so on. Meanwhile, the receiving process parameters are character string types and are obtained through driver function analysis.

It should be noted that, the preset request parameter list includes a list of parameters of cam_enable, lcd_enable, flash_enable or cam_disable, lcd_ disable, flash _disable, and other parameters, which are not limited in this embodiment, and the application process of the current calling color temperature sensor is determined by matching with the process parameters recorded in the preset request parameter list, and the current calling color temperature sensor process is indicated by adopting a parameter distinguishing manner in this embodiment. The specific parameter list adopts an enumeration type:

in a specific implementation, process parameters of an application process using a color temperature sensor are matched with a preset request parameter list to obtain the number of processes which have called the color temperature sensor currently, for example, process parameters cam_enable and lcd_enable of the application process using the color temperature sensor are used to confirm which process is currently using a device, so that identification of the application process using the color temperature sensor currently is realized, a frame diagram is shown in fig. 6, the frame diagram is marked with a rough part, the type using the color temperature sensor is performed by adding a function parameter en-type on the basis of an original basic frame, and paths of other application processes are added on the basis of an original Cam and color_enable, so that all application processes passing through Linux R/W can call the color temperature sensor through the paths to the color_enable, the running state of the color temperature sensor is obtained through the color_enable, and the running state of the color temperature sensor is fed back. After the color temperature sensor is controlled to be powered on or powered off based on the zone bit, the method further comprises the following steps: setting waiting time for calling the color temperature sensor by the display process or the camera process respectively; monitoring the current use state of the color temperature sensor according to the waiting time; and determining whether the color temperature sensor is normally used according to the current use state.

In one possible implementation, a use state of a current color temperature sensor and a current call request are obtained; determining the actual running state of the color temperature sensor according to the using state of the current color temperature sensor and a current calling request query state machine table, wherein the query state machine table comprises the corresponding relation among the using state of the color temperature sensor, the calling request and the actual running state of the color temperature sensor; and controlling the color temperature sensor to operate according to the actual operation state.

In this embodiment, the current use states of the color temperature sensor may be Cam on, LCD on, cam off, and LCD off, which respectively indicate that the camera process calls the color temperature sensor to power up, the display process calls the color temperature sensor to power up, the camera process calls the color temperature sensor to power down, the display process calls the color temperature sensor to power down, and may also include the use states of other application processes using the color temperature sensor.

In a specific implementation, for example, when the use state of the current color temperature sensor is Cam on or LCD on and the current call request is cam_enable, it is indicated that the current existing application process is using the color temperature sensor, in this case, power-on processing is not required to be performed according to the cam_enable request, only the signal quantity counted by the process using the color temperature sensor by the application process is adjusted, when the use state of the current color temperature sensor is Cam on or LCD off and the current call request is cam_disable, it is indicated that only the current application process is using the color temperature sensor, in this case, power-off processing can be performed on the color temperature sensor, so that power-on and power-off operations on the color temperature sensor are performed according to the use state of the current color temperature sensor by the application process and the control request of the current color temperature sensor, and the purpose of effectively controlling the color temperature sensor is achieved.

In the corresponding code implementation, a switch-case mode is adopted, and an actual control flow is decided according to the value of the current process counting semaphore according to the issued parameter serving as a case condition, so that the function that two or more processes control the same device is realized. The embodiment is now described as a control flow of two processes, when a plurality of processes are the same in basic mechanism, the instruction and the state expansion need to be modified, so that the control flow is better compatible for the use of the processes, as shown in a control flow diagram in fig. 8, for example, the initial state of the color temperature sensor is in an off state, that is, the control parameters of the color temperature sensor used by the application process are cam_disable and lcd_disable, when the use of lcd_enable is received, the use state of the color temperature sensor is adjusted to Cam off and LCD on, and when the use of cam_enable is received, the use state of the color temperature sensor is adjusted to Cam on and LCD on.

It can be understood that the control logic up-shift scheme can also be adopted, namely, the bottom driver is still adopted to realize the process counting, but an interface for controlling the addition and subtraction of the process counting semaphore variable is provided for the upper layer; meanwhile, the driver process count semaphore and the data are reported together, and a path for the upper layer process to acquire the actual calling number of the bottom layer is opened. And then judging when the upper process calls the device interface, and ensuring that only the first process is actually electrically operated when the lower driver calls the enable for multiple times to enable the device, wherein the specific logic is as follows: 1. when the device needs to enable the device, the process counting semaphore is set to 0, the enable interface is directly called, and then an interface of the counting semaphore +1 is called to control the bottom layer semaphore; 2. after each frame of data is reported, analyzing the corresponding value of the counting semaphore, and maintaining a global variable at the current calling layer to store the value of the semaphore; 3. before the power-down interface is called, firstly judging the semaphore, if only the current process is in use, calling the power-down interface, otherwise, only calling the interface of the semaphore-1 to control the bottom semaphore, and not performing actual power-down operation.

The alternative scheme is to move up the scheme of the voting mechanism and realize control logic at the upper layer of each calling device, so that each process using the same device needs to realize the process logic to solve the scene problem.
