AI Technical Summary
Technical Problem
In traditional memory swapping schemes, page table information and metadata need to be updated when an interrupt occurs, making it difficult for the operating system to quickly resume the interrupted task and potentially causing a prolonged blockage.
Method used
Upon receiving the swap completion message from the target memory, the operating system interrupts the current task, updates the page table information of the memory block, and adds it to the memory swap task queue. This reduces the execution of metadata update tasks, avoids holding locks, and lowers the probability of prolonged blocking.
Benefits of technology
It improves interrupt recovery speed, reduces the impact on the operating system, and increases the efficiency of memory swapping.

Abstract
Embodiments of the present specification provide a memory exchange method and device, computer equipment and a storage medium, the method comprising: obtaining a to-be-processed exchange task, determining a memory block of data to be exchanged according to the to-be-processed exchange task, and sending an exchange request corresponding to the memory block to a target memory; when receiving an exchange completion message returned by the target memory, interrupting a first task currently being executed, and performing an operation of updating page table information of the memory block and adding a metadata update task of the memory block in a preset task queue, after the operation is completed, resuming the first task; if it is detected that a set condition is met, processing the metadata update task in the preset task queue.
