The first module is, for example, an on-screen display (OSD) service. After a user presses a hotkey, a chip of the terminal device generates a System Control Interrupt (SCI), an SCI generation event (i.e., WMI interrupt) is transmitted to an OSD service through an SCI event service in a Basic Input Output System (BIOS) and a WMI service (Winmgmt) in an Operating System (OS), and after receiving the SCI, the OSD service determines a function corresponding to the hotkey according to an identifier in the SCI generation event and implements the function.

The second indication information may be the same as the first indication information or may be different from the first indication information; that is, the WMI service may forward the first indication information to the WMI service, or may generate the second indication information based on the first indication information. After receiving the second indication information, the WMI module directly sends WMI interrupt to the WMI service without SCI event service processing, so that whether the WMI service is abnormal or not can be quickly determined.
In an optional embodiment, the method further comprises: if the first module receives WMI interruption in a first preset time period, the first module acquires identification information from the WMI module through WMI service, wherein the identification information is information associated with the identification in the first indication information; and if the first module does not receive the identification information in the second preset time period, the first module restarts the WMI service.
The first module receives WMI interruption in a first preset time period, and shows that the function of the WMI service in the first preset time period is normal. If the first module does not receive the identification information within the second preset time period, it may be that the WMI service has failed within the second preset time period, and the first module may attempt to repair the WMI service by restarting the WMI service.
In an optional embodiment, the method further comprises: if the first module receives WMI interruption in a first preset time period, the first module empties a first counter, and the first counter is used for recording the continuous restarting times of WMI service.

In an alternative embodiment, the first module restarts the WMI service, including: the first module restarts the WMI service when the value of a first counter is smaller than a first threshold value, and the first counter is used for recording the continuous restart times of the WMI service.
If the continuous restart times of the WMI service are smaller than the first threshold value, the first module can try to restart the WMI service for multiple times, and the probability of repairing the WMI service is improved.
In an alternative embodiment, the method further comprises: the first module increments a first counter by 1 upon restarting the WMI service.
If the continuous restart times of the WMI service are larger than or equal to the first threshold, the abnormal problem of the hot key function is difficult to solve by restarting the WMI service, the WMI service is continuously restarted, only signaling overhead and electric quantity consumption are increased, in this case, the WMI service is stopped to be restarted and the user is prompted that the hot key function is abnormal, and the number of the first counter is increased by 1, so that the WMI service is prevented from being restarted for too many times, and the signaling overhead and the electric quantity consumption are reduced.
In an optional implementation manner, the first module sends first indication information to the WMI service, including: the first module periodically transmits first indication information to the WMI service.

The first module can also send the first indication information according to the instruction of the user without periodically sending the first indication information, thereby reducing signaling overhead and electric quantity consumption. The embodiment is suitable for the terminal equipment in the power saving mode.

The first module is, for example, an on-screen display (OSD) service. After a user presses a hotkey, a chip of the terminal device generates a System Control Interrupt (SCI), an SCI generation event (i.e., WMI interrupt) is transmitted to an OSD service through an SCI event service in a Basic Input Output System (BIOS) and a WMI service (Winmgmt) in an Operating System (OS), and after receiving the SCI, the OSD service determines a function corresponding to the hotkey according to an identifier in the SCI generation event and implements the function. In general, the reason why the hotkey function is abnormal is that WMI service is abnormal, SCI generation events cannot be notified to APPs of an application layer, and restarting WMI service has a certain probability to solve the problem that WMI service cannot transmit SCI generation events. In this embodiment, after the OSD service sends the first indication information, if the OSD service does not receive WMI interrupt within the preset time period, it indicates that the WMI service is abnormal, and the OSD service may restart the WMI service, so that the problem of abnormal hot key function may be solved.

The first module receives WMI interruption in a first preset time period, and shows that the function of the WMI service in the first preset time period is normal. If the first module does not receive the identification information within the second preset time period, a fault may occur in the WMI service within the second preset time period, or a fault may occur in the OS within the second preset time period, the probability that the OS sends the fault is high, and the first module may attempt to repair the hot key function by restarting the OS.

In other embodiments of the present application, an apparatus suitable for use in the present application may include more or fewer components than shown in FIG. 1, or an apparatus suitable for use in the present application may include a combination of some of the components shown in FIG. 1, or an apparatus suitable for use in the present application may include sub-components of some of the components shown in FIG. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination of software and hardware.
The connection relationship between the modules shown in fig. 1 is merely illustrative, and is not intended to limit the connection relationship between the modules.
A hardware system suitable for the apparatus of the present application is described in detail above, and a software system suitable for the apparatus is described below. The embodiment of the present application takes a layered architecture as an example, and exemplarily describes a software system of the apparatus.
As shown in fig. 2, the software system adopting the layered architecture is divided into a plurality of layers, and each layer has a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the software system may be divided into three layers, an application layer, an OS layer, and a BIOS from top to bottom. The working flow of the software system is described below by taking hotkey detection as an example.
S210, after the user presses the hot key, the hot key generates a hardware signal.
S220, after detecting the hardware signal, the EC determines the identifier of the hot key corresponding to the hardware signal through row scanning and column scanning; subsequently, the EC triggers the SCI, i.e., the EC pulls down the SCI pin level of the EC; after the SCI event service senses that the level of the SCI pin of the EC is lowered, the EC queries the interrupt information through the LPC bus, and the EC reports the interrupt information to the SCI event service through the LPC bus, as shown in fig. 3.
Interrupt information reported by the EC to the SCI event service via the LPC bus is used to indicate a hot key press, and the interrupt information includes an Identifier (ID) of the hot key. Illustratively, ID 0x10 represents a hotkey F7; ID 0x11 indicates a hot key F8.
S230, the SCI event service converts the hotkey ID acquired from the EC into a hotkey ID corresponding to an on-screen display (OSD) service, and stores the hotkey ID corresponding to the OSD service in the WMI module.
And S240, generating a WMI interrupt by the SCI event service, and sending the WMI interrupt to the WMI service of the OS layer, wherein the WMI interrupt is used for informing the WMI service of the occurrence of the SCI event.
The execution sequence of S230 and S240 is not sequential.
S250, after receiving the WMI interrupt, the WMI interrupt is forwarded to the OSD service by the WMI service, wherein after the electronic equipment is started, the WMI interrupt monitoring is registered in the WMI service by the PC housekeeper through the OSD service, and the WMI interrupt monitoring is used for: and when the WMI interrupt is received by the WMI service, forwarding the WMI interrupt to the OSD service.
And S260, after receiving the WMI interrupt, the OSD service acquires the hot key ID corresponding to the OSD service from the WMI module through the WMI service, and specifically, the OSD service calls a Read/Write (Read/Write) interface of the WMI service to acquire the hot key ID corresponding to the OSD service from the WMI module (WMI method).
And after the OSD service of the computer manager APP receives the hot key ID corresponding to the OSD service, starting the corresponding hot key function. For example, the hotkey function corresponding to the hotkey function ID is to open a main interface of a computer housekeeper, and the computer housekeeper APP can control the display screen to display the interface shown in fig. 4.
In some cases, the WMI service may be abnormal and unable to notify the APP of the application layer of the SCI generation event (i.e., WMI interrupt), so that the notebook computer cannot display the interface shown in fig. 4 after the user presses the hot key.
The method for repairing a hot bond provided by the present application is described below. As shown in fig. 5. The method comprises the following steps.
S501, after the computer manager is started, a heartbeat command is sent to the WMI service through the OSD service at the first time, and the heartbeat command indicates the WMI service to call the WMI module to send WMI interrupt to the OSD service.
The heartbeat command may include a heartbeat ID1, and the specific form of the heartbeat command is not limited in the present application.
In an alternative embodiment, the computer steward may send the heartbeat command periodically, for example, every 30 seconds. When the hot key function fails, the hot key function can be automatically repaired through the steps described below, so that the problem of abnormal hot key function can be solved under the condition that a user feels no sense, and the user experience is improved.
In another alternative embodiment, the cyber attendant may receive a hot key function detection instruction of the user, and send a heartbeat command to the WMI service at a first time according to the hot key function detection instruction. Namely, the computer manager can wait for the user to find the hot key function fault and send the hot key function detection instruction, and then send the heartbeat command without periodically sending the heartbeat command, thereby reducing signaling overhead and electric quantity consumption. The embodiment is suitable for the terminal equipment in the power saving mode.
S502, after receiving the heartbeat command, the WMI service forwards the heartbeat command to a WMI module of the BIOS through the read/write interface, instructs the WMI module to generate WMI interruption, and sends the WMI interruption to the WMI service.
And S503, after receiving the heartbeat command of the WMI service, the WMI module generates a WMI interrupt and sends the WMI interrupt to the WMI service.
The WMI interrupt is used for testing whether the function of forwarding the WMI interrupt by the WMI is normal, and therefore the WMI interrupt can be any WMI interrupt.
And S504, after receiving the WMI interrupt, the WMI service forwards the WMI interrupt to the OSD service.
If the forwarding function of the WMI service is normal, the OSD service can receive WMI interruption in a first preset time period; if the forwarding function of the WMI service is abnormal, the OSD service cannot receive WMI interruption within a first preset time period. Therefore, the OSD service may determine whether the forwarding function of the WMI is normal according to whether the WMI interrupt is received within the first preset period.
The OSD service determines whether a WMI interrupt is received within a first preset period S505.
The first preset time period may be a time period with a duration of 1s from the first time, or other time periods, and the application does not limit features such as the duration of the first preset time period.
If the OSD service receives WMI interrupt within the first preset time period, the OSD service may send the heartbeat command again after waiting for 30 seconds, that is, send the heartbeat command again at the second time, and if the OSD service does not receive WMI interrupt within the preset time period after the second time, the OSD service may restart the WMI service in time, reducing the probability that the user perceives that the hotkey is abnormal.
If the OSD service does not receive the WMI interrupt within the preset time period, the OSD service may perform S506.
The OSD service determines whether the value of the counter 1 is less than a first threshold, i.e., the OSD service determines whether the number of consecutive restarts of the WMI service is less than the first threshold S506.
If the number of consecutive restarts of the WMI service is less than the first threshold (e.g., 5), the OSD service may proceed to S507.
The OSD service may call an interface (CreateProcessWithToken) to restart the WMI service and increment the value of counter 1 by 1S 507.
When the continuous restart times of the WMI service are less than the time threshold value, the OSD service can try to restart the WMI service for many times, and the probability of repairing the WMI service is improved.
After the WMI service is restarted, the OSD service may continue to send a heartbeat command to detect whether the function of the WMI service is restored to normal.
And if the restart times of the WMI service are greater than or equal to the first threshold value, the OSD service ends the hot key repair process.
When the restarting times of the WMI service is greater than or equal to the time threshold, the abnormal problem of the WMI service is difficult to solve through restarting, and the continuation of the restarting of the WMI service only can increase signaling overhead and electric quantity consumption.
If the OSD service receives the WMI interrupt within the preset time period, the OSD service may perform S508.
S508, the OSD service obtains the heartbeat information from the WMI module through the WMI service.
The OSD service can call the WMI module to report heartbeat information through the WMI service, the WMI module sends the heartbeat information to the WMI service based on the call of the WMI service, the heartbeat information comprises a heartbeat ID2, and the heartbeat ID2 is a heartbeat ID generated by the WMI module based on the heartbeat ID 1. And after receiving the heartbeat information, the WMI service forwards the heartbeat information to the OSD service.
If the forwarding function of the WMI service is normal, the OSD service may receive heartbeat information within a second preset time period; if the forwarding function of the WMI service is abnormal, the OSD service cannot receive the heartbeat message within the second preset time period. Therefore, the OSD service may determine whether the forwarding function of the WMI is normal according to whether the heartbeat information is received within the second preset period.
S509, the OSD service determines whether the heartbeat information is received within a second preset time period.
The second preset time period may be a time period with a duration of 2s from the first time, or may be other time periods, and the present application does not limit features such as the duration of the second preset time period.
If the OSD service does not receive the heartbeat message within the second predetermined period, the OSD service may perform S506.
If the OSD service receives the heartbeat message within the second predetermined period, the OSD service may perform S510.
S510, the OSD service clears the counter 1, and executes S501 after waiting 30S.
In the method shown in fig. 5, the information interaction flow of each module is shown in fig. 6.
The reason for the abnormal hot key function may be that communication between the EC and the BIOS is abnormal, the EC cannot transfer the SCI to the BIOS, and the problem cannot be solved by restarting the WMI service. Another method of repairing the hot key function provided by the present application is described below. This method is illustrated in fig. 7.
And S701, after the computer housekeeper is started, sending a heartbeat command to the WMI service at the third moment, wherein the heartbeat command instructs the WMI service to call the WMI module to send WMI interrupt to the WMI service.
The heartbeat command may include a heartbeat ID1, and the specific form of the second heartbeat command is not limited in the present application.
In an alternative embodiment, the computer butler may send the heartbeat command periodically, for example, every 30 seconds. When the hot key function breaks down, the hot key function can be automatically repaired through the steps described below, so that the problem of abnormal hot key function can be solved in time before a user senses that the hot key function breaks down, and the user experience is improved.
In another alternative embodiment, the cyber attendant may receive a hot key function detection instruction of the user, and send a heartbeat command to the WMI service at a third time according to the hot key function detection instruction.
In the embodiment, the computer manager can send the heartbeat command after the user finds the hot key function fault and sends the hot key function detection instruction, and does not need to send the heartbeat command periodically, so that the signaling overhead and the power consumption are reduced. The embodiment is suitable for the terminal equipment in the power saving mode.
S702, after receiving the heartbeat command, the WMI service forwards the heartbeat command to the WMI module of the BIOS through the read/write interface, instructs the WMI module to generate WMI interrupt, and sends the WMI interrupt to the WMI service.
After receiving the heartbeat command, the WMI service calls an advanced configuration and power interface source language (ASL) method (WMI method) of the BIOS to execute an SCI reporting procedure, that is, instructs the WMI module to generate an interrupt event, and writes the interrupt event into an EC Random Access Memory (RAM).
And S703, the WMI module generates an interrupt event based on the calling of the WMI service and writes the interrupt event into the EC RAM.
The interrupt event is used to test whether the SCI reporting process is normal, and therefore, the interrupt event may be any interrupt event capable of testing whether the SCI reporting process is normal.
The EC RAM is memory internal to the EC, and the WMI module may write interrupt events to the EC RAM through 62/66 input/output (I/O) ports.
S704, the EC triggers the SCI after receiving the interrupt event, i.e., the EC pulls down the SCI pin level.
S705, SCI event service senses the EC' S SCI pin level down, querying the EC for interrupt information via the LPC bus.
S706, the EC reports SCI interrupt information to the SCI event service via the LPC bus, where the interrupt information includes heartbeat information (including heartbeat ID 1), and the heartbeat information indicates that the interrupt information is used for a heartbeat test.
S707, after receiving the SCI interrupt information (including heartbeat information and corresponding ID 1), the SCI event service generates a corresponding WMI interrupt (including heartbeat information and corresponding ID 2) according to the SCI interrupt information.
S708, the SCI event service stores the WMI interrupt to the WMI module.
S709, the SCI event service reports WMI interrupt to the WMI service.
S710, the WMI service reports WMI interrupt to the OSD service.
After receiving the WMI interrupt, the WMI service forwards the WMI interrupt to the OSD service, wherein after the electronic device is powered on, the PC housekeeper registers WMI interrupt monitoring in the WMI service through the OSD service, and the WMI interrupt monitoring is used for: and when the WMI interrupt is received by the WMI service, forwarding the WMI interrupt to the OSD service.
The OSD service determines whether a WMI interrupt is received S711.
If the forwarding function of the WMI service is normal, the OSD service can receive WMI interruption within a preset time period; if the forwarding function of the WMI service is abnormal, the OSD service cannot receive WMI interruption within a preset time period. Therefore, the OSD service may determine whether the forwarding function of the WMI is normal according to whether the WMI interrupt is received within a preset time period.
The preset time period may be a time period with a duration of 1s from the third time, or other time periods, and the present application does not limit the characteristics of the preset time period, such as the duration.
S712, if the concierge does not receive WMI interruption within the preset time period, the OSD service determines whether the value of the counter 1 is smaller than a first threshold, wherein the counter 1 is used for recording the continuous restart times of the WMI service.
If the numerical value of the counter 1 is greater than or equal to the first threshold value, the OSD service ends the process, and the WMI service is not repaired; if the value of the counter 1 is smaller than the first threshold, the OSD service performs S713.
S713, the OSD service restarts the WMI service and increments the value of the counter 1 by 1.
After the WMI service is restarted, the OSD service may perform S701.
If the computer administrator receives the WMI interrupt within the preset time period, the OSD service proceeds to S714.
S714, the OSD service clears the counter 1, and obtains heartbeat information from the WMI module through the WMI service, and specifically, the OSD service calls a Read/Write (Read/Write) interface of the WMI service to obtain heartbeat information (corresponding to ID 2) from the WMI module (WMI method).
S715, the OSD service determines whether the heartbeat information is received within a second preset time period.
S716, if the heartbeat message is received within the second preset time period, the OSD service determines that the WMI service normally operates. The OSD service clears the counter 2, and executes S701 after waiting for 30 seconds, where the counter 2 is used to record the number of consecutive restarts of the OS.
S717, if the heartbeat message is not received within the second predetermined period, the OSD service determines whether the value of the counter 2 is less than the second threshold.
When the restart times of the OS is greater than or equal to the second threshold, it is indicated that the problem of the abnormal hot key function is difficult to be solved by restarting the OS, and continuing to restart the OS may only increase signaling overhead and power consumption, and in this case, stopping restarting the OS and prompting the user that the abnormal hot key function exists, may reduce the signaling overhead and power consumption.
If the value of the counter 2 is smaller than the second threshold, the OSD service proceeds to step S718.
And S718, restarting the OS.
