Description

Signal processing method, apparatus, storage medium, and program product Technical Field The present application relates to the field of communications technologies, and in particular, to a signal processing method, apparatus, storage medium, and program product. Background A host (host) may enumerate electronic devices, such as peripheral component interconnect express (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIE) devices, to discover, identify, and configure the electronic devices connected to the host. In some cases (such as where the signal is unstable) this may result in enumeration failure, the host needs to reset the electronic device to re-enumerate. In one manner, the host may trigger the electronic device to reset by sending a signal to a boot and reset (BBRST) pin of the electronic device. However, if the BBRST pins are not standard pins specified by PCIE protocol and the host does not store information about BBRST pins, the host will not recognize and operate BBRST pins, which may cause reset failure of the electronic device, and thus cause enumeration failure, thereby affecting implementation of functions of the electronic device. Therefore, how to reduce the probability of enumeration failure is a problem. Disclosure of Invention The embodiment of the application provides a signal processing method, equipment, a storage medium and a program product, which can reduce the probability of enumeration failure. In a first aspect, an embodiment of the present application provides a signal processing method, where the method may be applied to an electronic device, for example, an electronic device or an apparatus in an electronic device. The method comprises the steps that the electronic equipment reads a reset enabling state of a persistent reset signal in a starting stage, receives the persistent reset signal in an enumeration stage, and resets the equipment based on the persistent reset signal under the condition that the reset enabling state of the persistent reset signal is enabled. In the method, the electronic device can reset the device based on the persistent reset signal in the enumeration stage according to the reset enabling state of the persistent reset signal determined in the start-up stage. The method is beneficial to the electronic equipment to clear the abnormal state of the equipment before reset so as to re-enumerate, and the probability of enumeration failure is reduced. In the method, the lasting reset signal is a PCIE signal, which is beneficial to ensuring the successful reset of the electronic equipment and reducing the enumeration failure probability of the electronic equipment when the host is restarted. In an alternative implementation mode, the electronic device resets the device based on the persistent reset signal under the condition that the reset enabling state of the persistent reset signal is enabled, specifically, the electronic device resets the device based on the persistent reset signal under the condition that the reset enabling state of the persistent reset signal is enabled and the persistent reset signal is high level. In this embodiment, when the persistent reset signal is high, it is indicated that the host has sent the persistent reset signal to the electronic device. The electronic device can determine that the electronic device should reset the device based on the persistent reset signal according to the reset enabling state of the persistent reset signal determined in the starting stage, so that the electronic device is facilitated to clear the abnormal state of the device, and the probability of enumeration failure is reduced. In an alternative embodiment the electronic device further performs the step of performing a functional reset based on the persistent reset signal if the reset enable state of the persistent reset signal is not enabled. In this embodiment, when the reset enable state of the persistent reset signal is disabled, the persistent reset signal is used to trigger the electronic device to perform function reset, so that the electronic device may initialize a function (such as a PCIE function) of the electronic device. In an alternative implementation mode, the electronic device performs function reset based on the persistent reset signal under the condition that the reset enabling state of the persistent reset signal is not enabled, specifically, the electronic device performs function reset based on the persistent reset signal under the condition that the reset enabling state of the persistent reset signal is not enabled and the persistent reset signal is at a high level. In this embodiment, when the persistent reset signal is high, it is indicated that the host has sent the persistent reset signal to the electronic device. The electronic device can determine that the electronic device should perform function reset based on the persistent reset signal according to the reset enabling state of the persistent reset signal determined in
