Abstract
This application provides a quick start method. When a software fault occurs in a device, a restart request is called through a customized interface that complies with an instruction set specification, to indicate firmware to restart system software; and an image of the system software such as an operating system, a hypervisor, or a Trusted Execution Environment (TEE) is loaded to restart the system software, without resetting hardware. This skips a hardware initialization process, and shortens time required for restarting the device. When a hardware fault occurs in the device, a suspend request is triggered to indicate to freeze a process of system software, and indicate firmware to store a snapshot of status information of a hardware device and perform a hardware reset operation. After the hardware is reset, the hardware device is restored to a status before reset based on the snapshot.
