Accompanying drawing explanation
Fig. 1 is the method flow diagram of a kind of multisystem changing method for mobile terminal of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
First, please refer to Fig. 1, Fig. 1 is the method flow diagram of a kind of multisystem changing method for mobile terminal of the present invention, and described changing method comprises the following steps:
Step 101: perform high I/O operation task by nucleus module in advance;
Step 102: after scheduler module receives systematic evaluation order, clones nucleus module subprocess by the nucleus module performing too high I/O operation task;
Step 103: the nucleus module subprocess cloned starts the target of switching from system;
Wherein, in main partition, comprise three modules, i.e. scheduler module, nucleus module and nucleus module subprocess.
Particularly, in described changing method, the mode of operation of described scheduler module has two kinds: power on mode and handover module.
Mobile terminal is in power on mode, and described changing method comprises: after mobile terminal-opening, the main partition startup that main system is corresponding; Main partition starts its scheduler module; Scheduler module starts nucleus module; Perform high I/O operation task by nucleus module in advance, nucleus module enters wait command state after executing described high I/O operation task; Scheduler module sends to nucleus module and clones order for the first time; Nucleus module is in wait command state, and when receiving scheduler module to the first time clone order that nucleus module sends, nucleus module clones nucleus module subprocess, and the process number of the nucleus module subprocess cloned is sent to scheduler module; The nucleus module subprocess cloned starts first from system.
Mobile terminal is in switch mode, described changing method comprises: running of mobile terminal current from system time, scheduler module surveillance switching command, current core module subprocess is then terminated when receiving systematic evaluation order, exit corresponding current from system of current core module subprocess, and again send clone's order to nucleus module, nucleus module subprocess is again cloned with control core module, the process number of the nucleus module subprocess again cloned is sent to scheduler module, the nucleus module subprocess again cloned starts the target of switching from system, wherein, when scheduler module exits corresponding current of current core module subprocess from system and again do not send clone's order to nucleus module after, nucleus module enters wait command state again.
Wherein, nucleus module subprocess start comprise from system: load from the configuration information from subregion corresponding to system, start from system corresponding from subregion.
Wherein, systematic evaluation order can be clicked switched system button to trigger by user; Can comprise users personal data in subregion, described users personal data can comprise third-party application, wallpaper, theme, user file and user picture; Described loading, from the configuration information from subregion corresponding to system, starts from corresponding can the comprising from subregion of system: load from the users personal data from subregion corresponding to system; Described loading can comprise from the users personal data from subregion that system is corresponding: load and start from the corresponding third-party application from subregion, wallpaper and the theme of system; Scheduler module starts nucleus module and can comprise: scheduler module performs fork operation and namely creates process operation startup nucleus module; Scheduler module performs execute operation and executive process file operation, starts and performs high I/O operation task by nucleus module in advance; Clone's order that scheduler module adopts socket or property communication mode to send to nucleus module; Scheduler module performs kill operation and namely terminates process operation to terminate current core module subprocess.
In addition, the English original meaning of socket is " hole " or " socket ".As the Interprocess Communication Mechanism of BSD UNIX, get the rear one meaning.Usually also referred to as " socket ", for describing IP address and port, being the handle of a communication chain, can being used for realizing the communication between different virtual machine or different computer.Main frame on internet has generally run multiple service software, provides several service simultaneously.A socket is all opened in often kind of service, and is tied on a port, and different ports corresponds to different services.Socket as its English original meaning, as a porous socket.A main frame is just as being covered with the room of various socket, and each socket has a numbering, and some sockets provide 220 volts of alternating currents, and what have provides 110 volts of alternating currents, and what have then provides cable television program.Plug is inserted into the socket of different numbering by client software, just can obtain different services.
The present invention in order to avoid in net system switching process due to long delay problem that high I/O operation causes, high I/O operation is placed in nucleus module process before handover and is processed by employing prestrain technology in advance, thus construct the switch mode being specifically designed to the mobile terminal with multisystem, improve based on multi partition design multisystem between switch speed, be particularly suitable for customize Android system.
Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; to enable those skilled in the art better understand this patent content; should not be understood as the restriction to this patent protection range; as long as according to this patent disclose any equivalent change done of spirit or modification, all fall into this patent protection range.
