Process management method and electronic device

An electronic device, comprising:

• one or more processors;
• a storage, coupled to the one or more processors and storing computer program code comprising computer instructions, wherein the storage further comprises a volatile memory and a non-volatile memory, and the volatile memory and the non-volatile memory form a hybrid memory;
• and
• wherein the one or more processors execute the computer instructions, to enable the electronic device to perform the following:
• in a process in which the electronic device starts a system for a first time, generating data of a first process in the volatile memory, wherein duration in which the electronic device completes starting the system for the first time is T1, and the first process is a process recorded in a to-be-persistent process list in the electronic device;
• wherein the non-volatile memory comprises a non-volatile process file system which comprises a superblock, a process control block node, a page bitmap, and a persistent process file data block;
• in a running process of the system of the electronic device, migrating, the data of the first process to the non-volatile memory, including:
• migrating, by the electronic device, a process control block of the first process to the process control block node in the non-volatile process file system;
• migrating, by the electronic device, a page in a page tree table of the first process to the persistent process file data block, wherein the process control block of the first process and the page in the page tree table of the first process form a first persistent process file in the non-volatile process file system, and the process control block of the first process is used as an identifier of the first persistent process file;
• and
• keeping normal running of the system of the electronic device;
• in a process in which the electronic device starts the system for a second time, linking, the data of the first process in the non-volatile memory to a system process linked list, wherein duration in which the electronic device completes starting the system for the second time is T2, and T2 is less than T1;
• and
• wherein the system process linked list includes a plurality of process control blocks (PCBs) corresponding to a plurality of different persistent processes run by the electronic device.

A chip system, wherein the chip system is used in an electronic device comprising a hybrid memory including a volatile memory and a non-volatile memory, and comprises one or more processors configured to execute computer instructions, to enable the electronic device to perform the following:

• in a process in which the electronic device starts a system for a first time, generating data of a first process in the volatile memory, wherein duration in which the electronic device completes starting the system for the first time is T1, and the first process is a process recorded in a to-be-persistent process list in the electronic device;
• wherein the non-volatile memory comprises a non-volatile process file system which comprises a superblock, a process control block node, a page bitmap, and a persistent process file data block;
• in a running process of the system of the electronic device, migrating, the data of the first process to the non-volatile memory, including:
• migrating, by the electronic device, a process control block of the first process to the process control block node in the non-volatile process file system;
• migrating, by the electronic device, a page in a page tree table of the first process to the persistent process file data block, wherein the process control block of the first process and the page in the page tree table of the first process form a first persistent process file in the non-volatile process file system, and the process control block of the first process is used as an identifier of the first persistent process file;
• and
• keeping normal running of the system of the electronic device;
• in a process in which the electronic device starts the system for a second time, linking, the data of the first process in the non-volatile memory to a system process linked list, wherein duration in which the electronic device completes starting the system for the second time is T2, and T2 is less than T1;
• and
• wherein the system process linked list includes a plurality of process control blocks (PCBs) corresponding to a plurality of different persistent processes run by the electronic device.
