The application discloses a process recovery method, product, device and storage medium, and relates to the technical field of computers, and comprises the following steps: adding magic numbers in a process control block corresponding to target software in advance, identifying the process control block based on the magic numbers in a target memory address when detecting that a new kernel is started, and reserving data in the process control block and process context information in a running process of a target process in system memory, so that the target process is recovered based on the information reserved in the system memory. In this way, the data recovery process from a disk to memory can be reduced, and the time consumption of process recovery is reduced, so that the efficiency of process recovery is improved, and the influence on business operation is reduced. Therefore, the time consumption problem of reading memory data in the disk and returning the memory data to the memory during process recovery can be solved, the process recovery speed is greatly improved, the business interruption time is shortened, and the influence of kernel switching on business is reduced.

The present disclosure discloses a process hard interrupt method and related device, a breakpoint address is written in advance in a process control block of the process, the hard interrupt method comprises: when the process is scheduled to a running state, obtaining the breakpoint address from the process control block; writing the obtained breakpoint address into an emptied debug address register, so that a debug unit executes a hard interrupt based on the breakpoint address stored in the debug address register during running of the process. The present disclosure enables the processor to execute the hard interrupt on the single process even if the scontext is not set in the debug unit.
