Embodiment
The embodiment of the present invention provides a kind of starting up's method and device of mobile terminal, when liquid crystal panel LCD is carried out Refresh Data, the initialization unloading phase that MDP, MIPI DSI and LCD IC being carried out kernel, carry out liquid crystal display in start-up phase by the master cpu for the platform of developing mobile terminal, avoid unstable due to the platform that is used for the exploitation mobile terminal and the state machine between LCD IC, and then occurred surely shielding phenomenon when having avoided the startup mobile terminal.
As shown in Figure 1, the embodiment of the present invention provides a kind of starting up's method of mobile terminal, comprising:
S101, the mobile industry processor interface primary data path MIPI MDP clock of startup, and make it stay open state;
S102, when LCD is carried out Refresh Data, the initialization the unloading phase that MDP, MIPI DSI and LCD IC being carried out kernel.
When carrying out the loading of each peripherals and initialization when at kernel the unloading phase, temporarily postpone MDP, the initialization the unloading phase of MIPI DSI, the kernel of LCD IC.When LCD is carried out Refresh Data, then to MDP, the initialization the unloading phase that MIPI DSI and LCD IC carrying out kernel.Before this, main or continuity by the master cpu of the platform that is used for the exploitation mobile terminal the unloading phase demonstration work completed, MDP still continues to refresh the LOGO data from the display buffer of the OEMSBL of original device manufacturer, until when LCD is carried out Refresh Data, namely boot LOGO shows and finishes.Thereby avoided the situation for platform and the abnormal state of LCD IC when carrying out the state switching of exploitation mobile terminal, also avoided mobile terminal the problem of fixed screen to occur, wherein for the master cpu of the platform of developing mobile terminal, be mainly used to carry out the task requests of communication data inter-related task and respective application processor (AP).
Wherein, in step S102, LCD is carried out Refresh Data, can be specially the frame buffer (Framebuffer) of opening LCD.
MDP, MIPI DSI, the initialization unloading phase of the kernel of LCD IC comprises: the driver element that triggers the Execution driven program in the implementation of application program is registered MDP, MIPI DSI, LCD IC, simultaneously, load LCD and program corresponding to back light apparatus, thereby by LCD and corresponding program start LCD and the back light apparatus of back light apparatus.
Usually, driver is arranged in the kernel spacing of the operating system of mobile terminal, and application program is arranged in the user's space of the operating system of mobile terminal.
Trigger drive unit is to MDP, MIPI DSI, and LCD IC registers, and specifically comprises:
Determine to exist and be used for indicating the register node of not carrying out MDP, MIPI DSI and LCD IC registration;
Trigger described driver element to MDP, MIPI DSI, LCD IC registers.
Concrete, as shown in Figure 2, in order to realize MDP, the initialized postponement the unloading phase of MIPI DSI, the kernel of LCD IC, the step that is mainly concerned with modification is as follows:
S201, the boot (Appsboot) before kernel is started are modified, make MIPI MDP clock stay open state when kernel starts, thereby the hardware device that guarantees the display part keeps work when kernel starts, make MDP, can carry out at any time initialization unloading phase of MIPI DSI, the kernel of LCD IC;
S202, (for example late_display.c) modifies to driver, pass through to revise the hour of log-on global variable (int late_display) in kernel default configuration file (defconfig) in driver, delay MDP, MIPI DSI, the hour of log-on of LCD IC in driver, and increase register node in driver, make application program access driver when refreshing the first frame data, determine whether comprise this register node in driver, during this node in having access to driver, make again driver carry out MDP, MIPI DSI, the registration of LCD IC,
Concrete, to revise the function that shows that relevant initialization files (for example module_init) load in kernel, and according to the delay in defconfig registration option determine needs with driver to MDP, MIPI DSI, the hour of log-on of LCD IC is delayed, wherein, show that relevant initialization files can be specially mdp.c, msm_fb.c, mipi_dsi.c, mipi_lcd.c etc.;
simultaneously, also need to set up register node in driver, application program is access driver when refreshing the first frame data, determine whether comprise this register node in driver, if comprise this register node, make driver carry out MDP, MIPI DSI, the registration of LCD IC, then application program loads corresponding hardware device, realize MDP, MIPI DSI, LCD IC initialization, concrete, increase register node in driver, be specially and add this register node in internal memory virtual disk file system (ramdiskfs), the register node set up in driver can be/dev/late_display/control.
S203, application programs are modified, access driver when making application program carry out Refresh Data to LCD, and when confirmation is determined to have register node in driver, make driver carry out MDP, MIPI DSI, the registration of LCD IC;
In the system architecture of the operating system of mobile terminal, the hardware device of Kernel Driver operation is with an abstract form with library file in middle layer dedicates application access to, in order to guarantee Security of the system, the hardware device interface of application access driver need to carry out the checking of authority, thus the direct access driver of application program, therefore, realize MDP, initialized postponement unloading phase of MIPI DSI, the kernel of LCD IC also comprises:
The authority of S204, change application program makes the application program can access driver.
Wherein, the execution sequence of S201-S204 can be adjusted, and in practical application, those skilled in the art can select better order to carry out S201, S202, S203, S204, also can select to carry out simultaneously S201, S202, S203, S204.
like this, during the hour of log-on global variable of driver in moving to the defconfig configuration file, namely determine to postpone to carry out MDP, MIPI DSI, the registration of LCD IC, until application program is when carrying out Refresh Data to LCD, access driver, if determine existence/dev/late_display/control node in driver, illustrate that namely driver does not carry out MDP, MIPI DSI, the registration of LCD IC, make again driver complete MDP, MIPI DSI, the registration of LCD IC, then the application program loading of application programs to LCD and program corresponding to back light apparatus again, thereby by LCD and corresponding program start LCD and the back light apparatus of back light apparatus, realize MDP, MIPI DSI, LCD IC initialization.
