[0027] Power consumption management of a computer plays a vital role in improving its performance. Power consumption management refers to effectively managing and controlling the energy consumption of functional modules (such as a CPU (Central Processing Unit)) on a computer, reducing the power consumption of a computer system, and thereby improving the performance of the computer and prolonging the battery usage time. At present, a computer (PC) such as a notebook computer mainly realizes power consumption control through a corresponding driver module on its operating system. Once the driver module described above is abnormal, the power consumption of the computer cannot be controlled.

[0028] The drive module is a bottom-layer drive installed on an operating system, such as a drive independently developed by a computer manufacturer (referred to as a self-developed drive) or a drive developed by another system manufacturer, such as a DTT (Dynamic Tuning Technology) drive. The drive module can implement corresponding power consumption control according to a built-in drive policy. How the drive module implements power consumption control can be referred to related content. Abnormality of the drive module can be caused by operating system crash, drive module uninstallation or disablement, or drive module program error.

[0029] To solve the above problem, the basic idea of the present application is that when the drive module for power consumption management on the computer is abnormal, the EC (Embeded Controller) in the computer performs power consumption control.

[0030] Based on the above basic idea, the present application provides a power consumption control method, an embeded controller and an electronic device.

[0034] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] Before introducing the technical solutions provided by the embodiments of the present application, some terms involved in the present application are explained and described:

[0036] EC (Embeded Controller, embedded controller): It is a single-chip microcomputer (as an independent chip), mainly applied to mobile computer systems (such as notebook computers) or embedded computer systems, to provide keyboard control, touch screen control, part of power management, fan control, battery management, indicator (such as indicator light) control and other functions for such computers. In addition, it also controls the computer mainboard power sequence, and has an irreplaceable role in the computer startup process. In the computer, whether the computer is in the state of starting or shutting down, the EC will always remain in working condition, unless the battery in the computer is completely removed.

[0037] BIOS (Basic Input Output System, basic input output system), which builds a bridge between the underlying hardware and the upper operating system, is a set of programs (which can be called firmware programs) solidified into the ROM (Read only Memory, read-only memory) chip on the motherboard of the computer, mainly saving basic input output programs, system setting information, self-checking programs after booting and system self-starting programs, etc. The main function is to provide the most basic and most direct hardware settings and control for the computer. Among them, BIOS starts to run after the EC initializes the physical environment inside the computer. The programs provided by BIOS, such as Acppo.asl (a kind of ASL code program), define various functions required for communication with the operating system, hardware, etc. Such as Notify (a function used to notify related operations), Method (method function), Q_event (interrupt event function) and so on. ASL is a source program language used to define ACPI objects (including writing ACPI control methods).

[0038] SOC (System on a Chip, called system-level chip or system on chip), is an integrated circuit that integrates multiple functional modules of a computer, such as SOC that integrates CPU (Central Processing Unit, central processor), GPU (Graphics Processing Unit, image processor), DSP (Digital Signal Processing, digital signal processor) and various processors, as well as memory, input / output port, graphics card, etc.

[0039] OSPM (Operating System Power Management, operating system power management, which can be simply referred to as system power management), OSPM is the operating system (OS) as a system resource manager, according to the characteristics of work load and hardware resource power state, make power management decision and control under the condition of meeting system performance constraints, reduce system energy consumption.

[0040] ACPI (Advanced Configuration and Power Interface, Advanced Configuration and Power Interface), is a set of configuration hardware and power management specifications, is a standard specification for control, management and communication between hardware, operating system, and application program, which defines operating system, BIOS, underlying hardware. The functions that can be achieved by using ACPI include: system power management, device power management, processor power management, temperature management, system events, etc.

[0041] Acpi.sys is an ACPI driver, used as an interface between the operating system and the BIOS, usually deployed in the OSPM.

[0042] The architectural relationship between the EC, BIOS, SOC, OSPM, Acpi.sys, etc. described above can also be seen in Figure 3a

[0043] Figure 1 A flowchart of a power consumption control method provided by the present application is shown, the execution subject of the method is an embedded controller (EC) in an electronic device. The electronic device can be any computer containing an EC, such as a notebook computer, a tablet computer, an embedded industrial computer, a vehicle-mounted computer, etc. As shown in Figure 1 The power consumption control method provided by the present application includes the following steps:

[0044] 101, monitoring the device state of the electronic device, wherein the device state can reflect the power consumption of the electronic device;

[0045] 102, when an abnormal device state is monitored, determining whether the drive module for power consumption management in the electronic device is abnormal;

[0046] 103, when the drive module is abnormal, performing power consumption control on the electronic device.

[0047] In the above 101, the device state of the electronic device can include but is not limited to voltage information, temperature information (such as the temperature of the battery, CPU, GPU, etc.). Since the power consumption of the electronic device is often closely related to the temperature, specifically, during the operation of the electronic device, if the power consumption of functional components such as the battery, CPU, etc. increases, the corresponding heat generated will increase, thereby causing the temperature of the battery, CPU, etc. to rise, and the temperature rise will further increase the power consumption of the battery, CPU, etc. High power consumption and high temperature are one of the main reasons for the performance degradation and damage of functional components in the electronic device. Based on this, in the present embodiment, whether the electronic device has an abnormal device state can be determined mainly by monitoring the temperature information of the electronic device. Thus, in a specific implementation scheme, the above 101 "monitoring the device state of the electronic device" can include:

[0048] 1011, obtaining the temperature information of the electronic device.

[0049] In specific implementation, the temperature information of the electronic device can be actively obtained by a temperature sensor, and / or the temperature information of the electronic device can also be obtained according to the received temperature-related events. The temperature-related events can be triggered when the temperature of the electronic device is greater than a preset temperature threshold, and the temperature information of the electronic device includes but is not limited to the temperature of functional components such as the battery, CPU, GPU, power adapter, etc.​

[0050] For example, referring to Figure 2 For example, referring to

[0051] Alternatively, the temperature of the battery and the CPU in the above examples can be obtained by the EC according to the temperature-related event sent by the operating system to the battery and the CPU.

[0052] Accordingly, the "monitoring of the abnormal device state" in 102 can include:

[0053] When the temperature information exceeds the preset temperature threshold, it is determined that the abnormal device state of the electronic device is monitored.

[0054] For example, if the temperature of at least one of the battery, CPU, and other functional components exceeds the preset temperature threshold according to the obtained temperature of the battery, CPU, and other functional components, it can be determined that the abnormal device state of the electronic device is monitored.

[0055] In the above, the preset temperature threshold is flexibly set according to the actual situation, which is not limited here. When the temperature-related event of the electronic device is received, since the temperature-related event is usually triggered when the corresponding temperature is greater than the preset temperature threshold, it can be directly determined that the temperature information of the electronic device exceeds the preset temperature threshold.

[0056] Further, when the abnormal device state is monitored, it can be detected whether the drive module for power consumption management in the electronic device is in an active state, so as to determine whether the abnormal state of the electronic device is caused by the abnormality of the drive module, so that subsequent power consumption control of the electronic device is started in the case of determining that the abnormality of the drive module causes the abnormal state. The drive module has been described in detail above, and will not be described in detail here.

[0057] From the above, in an implementation, the "determining whether the drive module for power consumption management in the electronic device is abnormal" in 102 can specifically include:

[0058] 1021, detecting the module state of the drive module;

[0059] 1022, when the module state is an active state, determining that the drive module is normal;

[0060] 1023, when the module state is an inactive state, determining that the drive module is abnormal.

[0061] In a specific implementation, since the drive module is located on the operating system, the module state of the drive module can be detected periodically by a detection module in the electronic device which acts as a bridge between the EC and the operating system, so as to determine whether the final module state of the drive module is an active state or an inactive state according to the detection condition returned by the detection module within a certain time. Based on this, a specific implementation of the "detecting the module state of the drive module" in 1021 can be implemented by the following steps:

[0062] 10211, periodically notifying the detection module in the electronic device that it needs to send detection information to the drive module to detect the module state of the drive module at intervals of a first time length;

[0063] 10212, starting timing;

[0064] 10213, determining the module state of the drive module according to the detection response condition returned by the detection module before the timing length reaches a second time length; wherein the second time length is greater than the first time length.

[0065] In 10211, as mentioned in Figures 3a-3c , the detection module can be a basic input and output system in the electronic device 100. The basic input and output system can be BIOS. Of course, the basic input and output system can also be other types, such as PMON (Prom Monitor) similar to BIOS.

[0066] And, the first time length and the second time length in the step 1023 can be flexibly set according to actual conditions. For example, the first time length can be set to 1-4 seconds and the second time length can be set to no more than 20 seconds according to the response time that most users can accept.

[0067] In the step 10212, the timing can be achieved by starting a timer on the EC.

[0068] The following takes an example of the steps 10211-10213.

[0069] Figure 4b A specific implementation flowchart of the steps 10211-10213 is shown in FIG. 10, which is based on the steps 10211-10213 and Figure 3b combined with the steps 10211-10213. Figures 3a-3c Taking the detection module as the BIOS for example, a specific implementation flow of the steps 10211-10213 can be as follows:

[0070] The EC can call the interrupt event function Q_event in the BIOS once every first time length, such as 2 seconds, to send an interrupt notification to the BIOS once, so as to notify the BIOS that it needs to send detection information to the drive module once. Correspondingly, after receiving the interrupt notification, the BIOS will pause the execution of the current program and turn to process the interrupt notification. Specifically, the interrupt notification is processed as follows: a notification related operation function stored in itself is called, such as the Notify function, to send a detection information to the drive module. If the drive module is normal, after receiving the detection information, it will call the method function Method in the BIOS, and more specifically, it will call IMOK in the method function Method to make a detection response to the received detection information, and transmit the detection response to the EC through the BIOS; otherwise, if the drive module is abnormal, it will not receive the detection information, and will not make a detection response. For the EC, when it receives a detection response before the timing time length reaches the second time length, such as 10 seconds, it will stop periodically calling the interrupt event function Q_event to send an interrupt notification to the BIOS, and directly determine that the module state of the drive module is an active state, and will not start the power consumption control on the electronic device; and if the detection response is not received when the timing time length reaches the second time length, it is determined that the module state of the monitoring module is an inactive state, and the power consumption control on the electronic device is started.

[0071] Based on the above example, in a specific implementable technical solution, the step 10213 "determining the module state of the drive module according to the detection response returned by the detection module before the timing time length reaches the second time length" can be implemented by the following steps:

[0072] Before the timing time length reaches the second time length:

[0073] S1, when receiving a detection response returned by the detection module, determining that the drive module is in an active state, and stopping periodically informing the detection module of the need to send detection information to the drive module;

[0074] S2, if no detection response returned by the detection module is received, determining that the drive module is in an inactive state.

[0075] Wherein, the inactive state of the drive module can be caused by unloading or disabling the drive module, program error of the drive module or abnormal operation system (such as dead machine) and the like.

[0076] The above is mainly from the perspective of receiving a detection response in the second time length, directly determining that the drive module is in an active state and stopping periodically informing the detection module of the need to send detection information to the drive module, to describe an implementation scheme of the above step 10213. Of course, other ways can also be used to implement the above step 10213, for example, the drive module can be detected by the detection module periodically in the second time length, so as to finally determine the module state of the drive module by analyzing all detection responses received in the second time length. Based on this, in another specific implementation scheme, the above 10213 "determining the module state of the drive module according to the detection response returned by the detection module before the timing time length reaches the second time length", can be implemented by the following steps:

[0077] S1', determining the number of times of receiving the detection response returned by the detection module in the second time length;

[0078] S2', determining the continuous detection period of the drive module responding to the detection information according to the response parameter contained in the received detection response; wherein, the response parameter can represent the corresponding detection period;

[0079] S3', determining the module state of the drive module according to at least one of the number, the continuous detection period;

[0080] Wherein, the module state of the drive module in the active state includes at least one of the following: the number is greater than or equal to a first threshold, the number of continuous detection periods is greater than or equal to a second threshold. The module state of the drive module in the inactive state includes: the number is less than the first threshold and the number of continuous detection periods is less than the second threshold.

[0081] In practice, the first threshold value and the second threshold value are flexibly set according to actual conditions, but do not exceed the total detection period, wherein the total detection period is equal to the second time length divided by the first time length. Since the detection response contains a response parameter capable of representing the corresponding detection period, the EC can determine the detection period corresponding to the detection response according to the response parameter contained in the detection response, and mark the response state corresponding to the detection period. For example, if the detection response returned by the detection module is received within a detection period, the response state corresponding to the detection period can be marked as having been responded, which also represents that the state of the driving module corresponding to the detection period is an active state. Conversely, if the detection response returned by the detection module is not received within a detection period, the response state corresponding to the detection period can be marked as not having been responded, which also represents that the state of the driving module corresponding to the detection period is an inactive state.

[0082] The following Table 1 is an example. Through periodic detection of the driving module, the following content can be obtained (the total detection period is 5):

[0083] Table 1

[0084]

[0085] Based on the content in Table 1, it is assumed that the first threshold value is 2 and the second threshold value is 3. Then, the number of times the detection response returned by the detection module is received is 4 (greater than the first threshold value, i.e., 2), and the driving module responds to the received detection information in the third to fifth detection periods, i.e., the number of continuous detection periods in which the driving module responds to the detection information is 3 (equal to the second threshold value, i.e., 3). Therefore, it can be finally determined that the module state of the driving module is an active state.

[0086] The module state of the driving module is determined through the above steps S1' to S3'. Compared with the above steps S1 to S2, the accuracy of module state determination can be improved to some extent.

[0087] For example, it can be the case that the drive module is normal in the first detection period, and can receive the detection information and respond to the received detection information; and after that, due to sudden operating system crash, drive module uninstall or disable, or program exception of the drive module, etc., the detection response cannot be received in the subsequent detection period. In the above case, if the module state of the drive module is determined through the above steps S1-S2, the drive module will be directly determined to be in the active state due to the detection response returned by the detection module in the first detection period, and it is considered that the drive mode is executing power consumption control, so the detection of the drive module is stopped. However, in fact, the drive module is abnormal after the first detection period, and cannot execute power consumption control. In the above case, if the module state of the drive module is determined through the above steps S1'-S3', the detection response state received in all detection periods is analyzed, and it is finally determined that the drive module is in the inactive state, is abnormal, and cannot execute power consumption control, so the EC can immediately start the power consumption control function.

[0088] Specifically, when the EC determines that the drive module is abnormal, it can adjust the running information of the first functional component controlled thereby according to the self-built policy (EC Policy), and more specifically, the power consumption control policy, and can also notify the SOC to configure the working parameters of the second functional component thereon. Thus, in one implementation, the above 103 "when the drive module is abnormal, the electronic device is subjected to power consumption control", can specifically include:

[0089] 1031. When the drive module is abnormal, start the preset power consumption control policy;

[0090] 1032. According to the power consumption control policy, adjust the running information of the first functional component in the electronic device controlled by the embedded controller, and notify the system-on-chip in the electronic device to configure the corresponding working parameters for the second functional component thereon.

[0091] In a specific implementation, the power consumption control strategy includes an active strategy and a passive strategy. The active strategy can be used for the first functional component controlled by the EC to achieve the purpose of power consumption control. The passive strategy can be used for the second functional component on the system on chip (SOC) to reduce the power consumption of the second functional component and achieve the purpose of power consumption control. The first functional component can be, but is not limited to, a fan or a battery connected to the EC. The second functional component can be, but is not limited to, a CPU or a GPU integrated on the SOC. In addition, the EC can send an interrupt notification to the SOC by calling a Q_event function in the BIOS to notify the SOC to configure the working parameters of the second functional component on the SOC. Correspondingly, the SOC can call a Method function in the BIOS to respond to the interrupt notification to complete the working parameter configuration of the second functional component on the SOC, and can also feed back the configuration result to the EC.

[0092] The following examples illustrate how the EC controls the power consumption of the electronic device.

[0093] For example, to adjust the running information of the fan, the EC usually maintains a fan control table (ACPI table). Different fan speeds are set in the fan control table according to different temperatures of the CPU and the battery. The EC can read the target fan speed corresponding to the temperature of the CPU and the battery from the fan control table, generate a corresponding PWM (Pulse Width Modulation) signal according to the target fan speed, and send the PWM signal to the fan through the fan control circuit integrated on the EC to adjust the fan speed to the target fan speed, thereby achieving heat dissipation and temperature reduction.

[0094] For another example, the EC can send an interrupt to the SOC through the PECI bus to notify the SOC to configure the working parameters of the CPU, GPU, etc. on the SOC, so that the CPU, GPU, etc. work within a limited parameter range, thereby achieving power consumption control of the CPU, GPU, etc. For example, the SOC, in response to the interrupt notification, temporarily stops the execution of the current program and executes a related program for sending the working parameter configuration information of the CPU to the CPU. More specifically, the related program can execute a Method function in the BIOS to send the working parameter configuration information to the CPU through the Method function. The CPU completes parameter configuration according to the received working parameter configuration information, thereby limiting the working parameters of the CPU within a lower range to achieve the purpose of reducing the power consumption of the CPU. The working parameters include, but are not limited to, power limit (power limit value), voltage, operating frequency, etc. Alternatively, the EC can also control the CPU to perform a throttling action to achieve power consumption control of the CPU. Specifically, the EC can pull down the ProcHot# signal to make the CPU start the throttling action, and wait for the CPU temperature to return to a set value, and then restore the ProcHot# signal. The above-mentioned throttling refers to: within a fixed period, only one action is performed, if a new event is triggered, it is not executed; after the end of the period, if an event is triggered in the new period, it is executed. The above-mentioned ProcHot# is pulled out through a pin of the CPU and can be connected to the peripherals (such as the EC) of the CPU, and the peripherals send the ProcHot# signal.

[0095] The technical scheme provided by the embodiment can further determine whether the driving module for power consumption management in the electronic device is abnormal when detecting an abnormal device state of the electronic device, and start power consumption control of the electronic device when the driving module is abnormal. It can be seen that the present scheme can control the power consumption of the electronic device through the EC even if the driving module for power consumption management at the operating system level is abnormal, so as to avoid performance degradation and damage to components such as batteries caused by excessive power consumption of the electronic device.

[0096] Further, in order to enable the user to perceive that the module for power consumption management is abnormal, the current power consumption of the electronic device is switched to the EC for control, and a prompt information can also be output by the electronic device to prompt this. That is, the method provided by the embodiment can further include the following steps:

[0097] 104、outputting a prompt information to prompt that the driving module is abnormal and has been switched to the embedded controller for power consumption control.

[0098] In practice, the aforementioned prompts may be voice prompts played through the audio module of an electronic device, and / or text or graphics displayed through the display module (such as a screen) of an electronic device, or a combination thereof.

[0099] For example, see Figure 5 A pop-up window A appears on the display screen of electronic device 100, displaying the following text: "Power management driver module malfunction, switching to EC control. Please check the cause of the malfunction." After seeing this text, if the operating system is running normally, the user can check the driver module-related items in the electronic device's control panel to see if the driver module is disabled or uninstalled. If it is not disabled or uninstalled, further investigation can be conducted to determine if other reasons caused the driver module malfunction, such as errors in the driver module's program. Subsequently, if the driver module is detected to have returned to normal, the EC can stop power control and hand over power control to the driver module.

[0100] Furthermore, the method provided in this embodiment may also include the following steps:

[0101] 105. Display the power consumption information of the electronic device through the display module of the electronic device.

[0102] For example, see Figure 6 The left-hand diagram shows that, upon detecting a user's action on the "Performance" control in the Task Manager of electronic device 100, the device's power consumption information, such as CPU and memory consumption, is displayed on Task Manager interface B in response to that action. Alternatively, see [link to relevant documentation]. Figure 5 The right-hand image in the diagram can automatically and dynamically display power consumption information such as CPU and memory on the taskbar C of the electronic device 100, depending on user settings.

[0103] In summary, the technical solution provided in this application utilizes EC to enable power management of electronic devices even in the event of an abnormality in the driver module used for power management on the operating system.

[0104] See Figure 4a and Figure 4b The specific process of using EC to control the power consumption of electronic devices in this application is as follows:

[0105] 1. The EC monitors the temperature of the electronic device via a temperature sensor, and / or monitors the temperature of the electronic device based on received temperature-related events;

[0106] 2、When the temperature is monitored to exceed the preset temperature threshold, the EC will send an interrupt notification to the BIOS every interval, requiring the BIOS to detect whether the drive module for power consumption management (such as a self-developed drive or an intel DTT) is in an active state, and start timing;

[0107] 3、After receiving the interrupt notification, the BIOS will send Notify (for detection information) to the drive module to determine whether the drive module makes a corresponding detection response to the detection information;

[0108] 4、If the drive module calls the IMOK function in the BIOS to make a detection response, the BIOS will transmit the detection response made by the drive module to the EC when the IMOK is called, specifically, the response parameter (IMOK parameter) in the detection response is transmitted to the EC, which can represent the corresponding detection period.

[0109] 5、If the EC receives the detection response within the set time (i.e., before the timing duration reaches the set time), it directly determines that the drive module is normal and no longer sends an interrupt notification to the BIOS. If the EC does not receive the detection response within the set time, it starts power consumption control (such as adjusting the speed of the fan) on the electronic device, and notifies the SOC so that the SOC takes some related configurations on the CPU and the like, such as the EC can directly configure the Power Limit of the CPU through the PECI bus and the like.

[0110] Based on the above content, another embodiment of the present application provides a power consumption control method suitable for an embedded controller in an electronic device. As shown in Figure 7 , the power consumption control method comprises the following steps:

[0111] 201、When an abnormal temperature state of the electronic device is monitored, it is determined whether a drive module for power consumption management in the electronic device is abnormal;

[0112] 202、When the drive module is abnormal, the electronic device is subjected to power consumption control;

[0113] 203、Output prompt information to prompt that the drive module has been switched to the embedded controller for power consumption control.

[0114] Further, the method provided by the present embodiment can further comprise the following steps:

[0115] 204、Display the power consumption information of the electronic device through the display module of the electronic device.

[0116] For the specific implementation description of each step in the method provided in the above embodiment, refer to the related content in other embodiments, which will not be repeated here. In addition, the method provided in the embodiment can include other steps in addition to the steps described above. For the other steps that can be included and the specific implementation description, refer to the related content in other embodiments.

[0117] The application scheme will be introduced below in combination with a specific application scenario. Specifically:

[0118] Application scenario: notebook computer. The operating system of the notebook computer originally has a self-developed driver (for power consumption management) installed, but the self-developed driver is uninstalled (or disabled) due to user misoperation. In addition, the notebook computer also has EC, SOC (integrating CPU), BIOS, sensor (such as temperature sensor), etc.

[0119] In combination with Figures 3b-3c and Figure 4a , during the running of the notebook computer, the EC in the notebook computer monitors the temperature of the battery, power supply, CPU, etc. in real time through the temperature sensor, and monitors that the temperature of the battery exceeds the preset temperature threshold at t0. At this time, the EC will call the Q_event function in the BIOS of the notebook computer every 2 seconds (seconds) from t0 to periodically send an interrupt notification to the BIOS to inform the BIOS that it needs to detect whether the self-developed driver is in an active state. After receiving the interrupt notification, the BIOS sends Notify (detection information) to the self-developed driver. Since the self-developed driver is uninstalled, it cannot respond to Notify, so the EC will not receive the response of the self-developed driver through the BIOS within a set time such as 10 seconds. Therefore, from t0+10s, the EC will start to control the power consumption of the notebook computer, such as dynamically adjusting the speed of the fan, controlling the power limit of the CPU through the PECI bus, etc.
