Description

Communication fault processing method and electronic equipment Technical Field The present application relates to the field of electronic technologies, and in particular, to a method for processing a communication failure and an electronic device. Background The high-pass message interface (qualcomm MESSAGING INTERFACE, QMI) is a message communication mechanism for multiprocessor inter-process communication. QMI is widely used in electronic devices for communication between an application processor (application processor, AP) and a processor of a subsystem, and between an AP and an Application Digital Signal Processor (ADSP), among which QMI communication is one of them. There are a large number of QMI channels between the AP and the ADSP for various traffic data interactions, for example, sensor data interactions, audio data interactions, and power data interactions. Therefore, when the communication of the QMI channel is interrupted, it is important to resume the communication in time for the normal operation of the electronic device. In the conventional art, if a certain QMI channel communication between an AP and an ADSP is interrupted, the ADSP subsystem is restarted to resume the QMI channel communication. However, with this approach, all traffic in the ADSP subsystem is affected, affecting the user experience. Disclosure of Invention The application provides a communication fault processing method and electronic equipment, which can detect the fault condition of the QMI communication function of an ADSP, recover the QMI communication by adopting different restarting modes by different faults, prevent the influence on the business which does not have faults in the ADSP system while recovering the communication, and improve the user experience. In a first aspect, the present application provides a method for processing a communication failure, where the method is executed by an electronic device, the electronic device includes an application processor AP and an application digital signal processor ADSP, at least one first QMI channel for transmitting a service exists between the AP and the ADSP, a second QMI channel and a third QMI channel exist between the AP and a kernel layer of the ADSP, and the method includes, in a case where communication of the fourth QMI channel is abnormal, the AP sending a first message to the ADSP through the second QMI channel, the fourth QMI channel is any one of the at least one first QMI channel, the fourth QMI channel is used for transmitting data of a first service, if a response of the ADSP to the first message is not timed out, the AP sending a second message to the ADSP through the third QMI channel, the second message is used for requesting to restart a process corresponding to the first service in the ADSP, and if a response of the ADSP to the first message is timed out, the AP sends a first instruction to the ADSP, the first instruction is used for instructing to restart a subsystem running in the ADSP. The first QMI channel is also called the traffic QMI channel. The second QMI channel is also called a failure detection QMI channel. The third QMI channel is also referred to as a process restart QMI channel. The fourth QMI channel is, for example, a sensor QMI channel. The first message may be a detected broadcast message in a specific embodiment. The second message may be a process restart request message in a specific embodiment. The first instruction may be a subsystem restart instruction in a specific embodiment. In the communication failure processing method provided in the first aspect of the present application, when the fourth QMI channel is abnormal in communication, the AP sends a first message to the ADSP through the second QMI channel, and determines whether the system-level QMI communication function of the ADSP is normal according to the response of the ADSP to the first message. Since the second QMI channel is the channel between the AP and the kernel layer of the ADSP. Therefore, if the response of the ADSP to the first message is not overtime, it indicates that the system-level QMI communication function of the ADSP is normal, and may be that the process corresponding to the first service running in the ADSP fails, so that the fourth QMI communication function is abnormal, so that the communication of the fourth QMI channel is restored by restarting the process corresponding to the first service in the ADSP, thus preventing the influence on other processes in the ADSP, preventing the influence on other services, and preventing the influence on the use of the user. If the response of ADSP to the first message is overtime, it shows that the system-level QMI communication function of ADSP is abnormal, and the system-level QMI communication function is recovered by restarting the ADSP subsystem, so that the communication of the currently-found fault QMI channel (namely, the fourth QMI channel) is recovered, the communication of other QMI channels is
