All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As an optional implementation of the disclosure, an embodiment of the present invention provides a power state control method, which is applied to a processor of an electronic device, as shown in fig. 1, where fig. 1 is a flowchart of the power state control method provided in the embodiment of the present invention, and the power state control method includes:

S102: the processor responds to the interrupt request and controls the power state of the electronic equipment to be switched into one power state indicated by the state control instruction based on the state control instruction input by the user.
In the embodiment of the invention, when the electronic device is in the power-on state, a user applies corresponding operation to other hardware of the electronic device to enable the other hardware to output the trigger signal to the GPIO interface of the processor, the GPIO interface can generate an interrupt request representing a power state switching event of the electronic device and input the interrupt request to the processor, then the processor can respond to the interrupt request and control the switching of the power state of the electronic device to one power state indicated by the state control instruction based on the state control instruction input by the user, wherein the power state indicated by the state control instruction at least comprises a normal power-off state, so that the power state control function of other hardware of the electronic device, such as a power key, can be increased, and the use experience effect of the user is improved.
In some embodiments of the present invention, the other hardware of the electronic device may include a power key, and the receiving, by the processor, the interrupt request input by the GPIO interface includes: the processor receives an interrupt request input by the power key through the GPIO interface, the GPIO interface is configured to generate the interrupt request based on a trigger signal output by the power key, and the power key is configured to generate the trigger signal based on a short-press operation of a user.
When the electronic equipment is in a starting state, the power key outputs a level signal to the GPIO interface, if the power key is not pressed for a short time, the level signal output to the GPIO interface by the power key is kept unchanged, if the power key is pressed for a short time, the level signal output to the GPIO interface by the power key jumps, and after a GPIO controller of the GPIO interface monitors a jump edge (such as a rising edge or a falling edge) of the level signal, a corresponding interrupt request is generated and input to the processor, and the processor controls the power state of the electronic equipment to be switched to the power state indicated by the state control instruction by responding to the interrupt request and the state control instruction input by a user.
It should be noted that each GPIO interface corresponds to a setting register, and the state of the GPIO interface is configured through the setting register. When the data 0 is written into the flag bit of the register, the register disables the corresponding bit configuration interrupt of the GPIO interface, so that the GPIO interface enables the input and output functions; when the data 1 is written into the flag bit of the register, the register configures the corresponding bit of the GPIO interface to enable interrupt, so that the GPIO interface enables the interrupt trigger function. The BIOS system or OS system or the like may write data 1 or 0 into the register to enable or turn off the GPIO interrupt function through the register.
Of course, the present invention is not limited to this, and in other embodiments, other hardware of the electronic device may further include a sensor, for example, an optical sensor in the camera, and the user may trigger the optical sensor to generate a trigger signal by blocking the optical lens, and transmit the trigger signal to the GPIO interface of the processor, so that the GPIO interface generates an interrupt request indicating a power state switching event of the electronic device. In other embodiments, other hardware of the electronic device may also be a pressure sensor, and so on, which are not described herein again.
It should be noted that, in the embodiment of the present invention, when the electronic device is in the power-on state, the power key may be switched to the power state indicated by the state control instruction through the interrupt request after being pressed for a short time by the user, where the power state at least includes a normal power-off state; when the electronic equipment is in a power-off state, the power key can control the power state of the electronic equipment to be switched to a power-on state after being pressed by a user for a short time; when the electronic equipment is in a power-on state, the power key is pressed by a user for a long time, and the power state of the electronic equipment is controlled to be switched into a forced power-off state.
Wherein, the short-press of the power key means that the time for pressing the power key is between 1 second and 2 seconds, and the long-press of the power key means that the time for pressing the power key is more than 4 seconds. It is understood that the normal shutdown state is another shutdown state relative to the forced shutdown state. After the electronic equipment enters a normal shutdown state, the power supply of each part is stopped in sequence according to a power-down sequence; after the electronic device enters the forced shutdown state, the power supply of all the components can be stopped instantaneously. Although multiple forced shutdowns may cause irreversible damage to components of the electronic device, forced shutdown functionality is still required to restart the electronic device in the event that the operating system of the electronic device does not respond.
In some embodiments of the present invention, the power states indicated by the state control instruction may only include a normal shutdown state, but the present invention is not limited thereto.
Based on this, in some embodiments of the present invention, the electronic device may display a plurality of selectable power states through the human-computer interaction module or the display module, so that the user can select one of the power states. And, the user can input a state control command indicating a selected one of the power states through the man-machine interaction module or other hardware such as a power key or a sensor.
In some embodiments of the present invention, as shown in fig. 3, fig. 3 is a schematic structural diagram of another electronic device according to an embodiment of the present invention, where the electronic device further includes a human-computer interaction module 12, the human-computer interaction module 12 may include a touch display screen, and the human-computer interaction module 12 is connected to the processor 10, and after the processor 10 responds to an interrupt request, the method for controlling a power state further includes: the processor 10 controls the human-computer interaction module to display a plurality of power states of the electronic device, and receives a state control command input by the human-computer interaction module after a user selects one of the plurality of power states.
The example that a user needs to control the electronic device to enter a normal shutdown state is described, when the electronic device is in the startup state, after the user inputs an interrupt request to the processor through other hardware of the electronic device, such as a power key, the processor responds to the interrupt request to control the human-computer interaction module to display multiple power states of the electronic device, such as a normal shutdown state, a sleep state, a restart state, and the like, after the user selects one of the multiple power states, such as the normal shutdown state, the human-computer interaction module inputs a normal shutdown state control instruction to the processor, and the processor controls to switch the power state of the electronic device to the normal shutdown state based on the normal shutdown state control instruction.
Of course, the present invention is not limited to this, in other embodiments, the processor may further control the display screen to display multiple power states of the electronic device, and the user may further select one of the multiple power states by pressing the power key again or blocking the camera again, or by pressing the mouse or the keyboard, and input a state control instruction to the processor, which is not described herein again.
In some embodiments of the present invention, as shown in fig. 4, fig. 4 is a schematic structural diagram of another electronic device according to an embodiment of the present invention, where the electronic device further includes a power management module 13, the power management module 13 is configured to manage a power state of the electronic device, and the power management module 13 is connected to the processor 10. The processor 10 controls to switch the power state of the electronic device to one of the power states indicated by the state control instruction, including: the processor 10 controls the power management module 13 to switch the power state of the electronic device to a power state indicated by the state control instruction.
Taking other hardware as a power key as an example, as shown in fig. 5, fig. 5 is a schematic diagram of switching a power state provided in an embodiment of the present invention, when an electronic device is in a power-on state, after the power key is pressed for a short time by a user, a GPIO interface inputs an interrupt request to a processor, after the processor responds to the interrupt request and a state control instruction input by the user, the processor sends a control instruction to a power management module, and switches the power state of the electronic device to a power state indicated by the state control instruction by controlling the power management module, where one power state indicated by the state control instruction may be a normal power-off state, a sleep state, or a restart state.
In the embodiment of the present invention, the power key may also be directly connected to the power management module, as shown in fig. 5, when the electronic device is in the power-off state, the power key is pressed for a short time to input a power-on instruction to the power management module, so as to control the electronic device to power on; when the electronic equipment is in a power-on state, a forced power-off instruction is input to the power management module by long pressing of a power key, so that the electronic equipment is controlled to be forced to be powered off. The GPIO controller of the GPIO interface can determine whether the power key is pressed for a short time or a long time according to the jumping edge and the jumping duration of the output signal of the power key.
In some embodiments of the present invention, as shown in fig. 6, fig. 6 is a schematic structural diagram of another electronic device provided in the embodiments of the present invention, where the electronic device further includes a level conversion module 14, other hardware 11 of the electronic device is connected to the GPIO interface through the level conversion module 14, and the level conversion module 14 is configured to perform level conversion on a trigger signal output by the other hardware 11 and output the trigger signal to the GPIO interface.
Because the upper limit of the level of the GPIO interface of the processor is 1.8V, and the high-level signal of the power key is generally 3.3V, the level signal output by the power key can be converted into a proper level signal and then transmitted to the GPIO interface, so that the normal operation of the GPIO interface is not influenced.
In the embodiment of the present invention, at a BIOS (Basic Input Output System) start stage of a processor, a GPIO interface is initialized to have a GPIO function, and an interrupt trigger function is enabled. The BIOS system may describe an AEI object and a method (method) function unit through an Advanced Configuration and Power Management Interface (ACPI) table, and bind the AEI object to the GPIO controller, so as to respond to a trigger signal received by the GPIO Interface through the GPIO controller and the method function unit, where the ACPI table may also describe information such as an interrupt number and an interrupt trigger manner, so as to identify a trigger signal that can trigger an interrupt request from a signal received by the GPIO Interface.
When other hardware such as a power key outputs a trigger signal to the GPIO interface, the GPIO controller generates an interrupt request, the GPIO controller aggregates the interrupt request and sends the interrupt request to the interrupt controller, the interrupt controller sends the interrupt request to an interrupt service unit of an Operating System (OS for short) of each processor core, and the interrupt service unit routes the interrupt request to a method function unit described in an ACPI table for processing. Wherein, the interrupt service unit is described as Exx method in ACPI table, and xx represents the event number.
In the process that the processor responds to the interrupt request, the method function unit disables the interrupt source of the GPIO interface and clears the interrupt state bit of the GPIO interface, so that the GPIO interface cannot receive the trigger signal, and then the method function unit reports a power state switching event to the OS system in a notify mode, wherein the power state switching event can be represented as a 0x80 event and represents that a power key is short-pressed in a starting state, namely an S0 state. Then the OS system controls the human-computer interaction module to display the selectable power states, then the OS system enables an interrupt source capable of the GPIO interface to enable the GPIO interface to receive signals, then the OS system sends a control instruction to the power management module, and the power state of the electronic device is switched to be the power state indicated by the state control instruction by controlling the power management module.
