If the temporarily applied memory is used to set or get the xqc information, the driver releases the memory immediately after the hardware mailbox operation time exceeds the driver waiting time. However, the hardware does not cancel the operation, so the hardware may write data to released memory. Therefore, when the driver is bound to a device, the driver reserves memory for the xqc configuration. The subsequent xqc configuration uses the reserved memory to prevent hardware from accessing the released memory.
