Embodiment one

FIG. 1 is a flow chart of a method for starting a central control panel of an automobile provided by Embodiment 1 of the present invention.

With the development of automobile technology, most cars will be equipped with car central control screens. Drivers can easily control the car through the car central control screen and obtain driving assistance. The central control screen of the car has become the focus of the intelligent development of the entire car control. With the continuous integration of functions on the central control screen, the display content of various applications can be displayed on the central control screen. The display content of the display is not very helpful to the driver. According to the general driving habits of driving a car, only some functions, such as displaying images around the body to achieve safe and convenient driving, are the stage of preparing to start the car. necessary.

The embodiment of the present application realizes the acceleration of the start-up speed of the central control panel of the car through the characteristics that a large number of functions in the central control panel are not required during the start-up phase of the car, so that the driver can use the central control panel in the shortest time to assist in driving the car .

The method can be executed by a starting device for a central control panel of a car, and the starting device for the central control panel of a car can be implemented in the form of hardware and/or software.

As shown in Figure 1, this embodiment may include the following steps:

S110, during the process of starting the central control panel of the car, load the compressed kernel image, and decompress the compressed kernel image to obtain the kernel image;

S120 starts the kernel of the central control panel based on the kernel image, and includes one or more necessary drivers in the kernel.

Optionally, starting the kernel of the central control panel based on the kernel image includes the following steps:

If there are multiple necessary drivers, multiple CPUs are used to load the necessary drivers in parallel.

Optionally, after starting the kernel of the central control screen based on the kernel image, the method further includes the following steps:

mount the root file system;

Running the startup script, wherein, if there are multiple startup scripts independent of each other in the startup script, multiple CPUs are used to run the startup script in parallel.

Optionally, after running the startup script in the background, the method further includes the following steps:

Load one or more driver units, which are generated after compiling non-essential drivers.

Optionally, starting the kernel of the central control panel based on the kernel image includes the following steps:

When starting the kernel, identify critical log data;

Delete other log data except critical log data.

In this embodiment, in the process of starting the central control panel of the car, one can refer to the flow chart of starting the central control panel of the car in Figure 2, step S210, power on and start the central control The central control panel is started. After power-on and startup, it is necessary to start the CPU of the central control panel according to step S220. Then, the kernel image can be loaded according to step S230. Specifically, the kernel image can be pulled from the warehouse of the remote mirror warehouse service. Wherein, a mirror warehouse can contain multiple images, and the kernel image to be pulled can be determined in advance. The name and/or label of the kernel image that needs to be loaded can be located in the warehouse through the name and/or label.

After pulling the kernel image, in order to reduce the size of the kernel image, the kernel image obtained by pulling can be compressed by compressing the image, and then the compressed kernel image is generated, as shown in step S240 in Figure 2. The image is compressed to obtain a compressed kernel image. Compared with the uncompressed kernel image, the space occupied by the compressed kernel image will be reduced, specifically, it can be reduced by about 40%. The time spent on subsequent reading will also be greatly reduced, so as to speed up the opening of the central control screen.

During implementation, when compressing the kernel image, the compressed kernel image obtained after compression can be burned onto the memory of the device. Specifically, it can be stored in the EMMC (EMMC, Embedded MultiMedia Card, Embedded MultiMedia Card) on the circuit board. multimedia controller).

The compressed kernel image may be loaded from the memory storing the compressed kernel image, and then the compressed kernel image may be decompressed according to step S250 in FIG. 2 to obtain the kernel image.

When decompressing the compressed kernel image, the compressed kernel image can be input to the hardware decompression unit, and the compressed kernel image is decompressed by the hardware decompression unit. Utilizing the hardware decompression unit can reduce the decompression time compared with the CPU software decompression. In this embodiment, a compression and decompression algorithm that supports hardware acceleration can be used. After the acceleration of the hardware decompression unit is enabled, the time for decompressing the compressed kernel image will be greatly reduced. Specifically, the decompression time can be reduced by 50%.

In addition, the hardware decompression unit can also be equivalent to a set of multi-level registers. When decompressing, the storage capacity of the first-level registers will be smaller in order to improve the access speed, and the compressed kernel image can be divided into several parts. , the size of each divided compressed kernel image is the same as the size of the register storage capacity of the first level, or the size of each divided compressed kernel image is slightly smaller than the size of the first level register storage capacity.

When one of the compressed kernel images is input to the first-level register, the first-level register can start decompression to obtain the kernel image corresponding to the compressed kernel image, and then transfer the obtained kernel image to the next-level Store in the memory, and the first-level memory is empty at this time, and you can continue to receive another compressed kernel image and continue to decompress it. After the first-level memory decompresses all the split compressed kernel images, the complete decompressed kernel image can be read from the lower-level memory corresponding to the first-level memory.

In this embodiment, the CPU of the central control panel is activated for step S220 in FIG. 2 , where there may be multiple CPUs. Specifically, the processor on the central control panel has multiple CPU cores, and when the processor of the central control panel is started, the multiple CPU cores on it will start to run together correspondingly. Since the kernel of the central control screen includes one or more necessary drivers, the necessary drivers correspond to the content and functions that the driver needs to cooperate with the central control screen to display when starting the car, such as displaying images around the car, To cooperate with the driver to drive the car out of the parking space, for example, to show the distance between the car and obstacles, to avoid the car from scratching in the process of driving the car out of the parking space, etc.

For step S260 in Figure 2 to start the kernel of the central control panel, when there are multiple necessary driver programs, multiple CPUs can be used to load the necessary driver programs in parallel, and each different CPU corresponds to a different necessary driver program to realize loading , and memory management, etc. Using multiple CPUs to load the necessary drivers in parallel can make full use of the advantages of the central control panel using multi-core CPUs. Exemplarily, there are currently three necessary driver programs A, B, and C that are not related to each other, and the loading of A, B, and C can be performed by different CPUs at the same time. In the currently adopted method, although most processors are multi-core, only one CPU core is always used when starting the kernel, that is, A needs to be processed first, then B is processed, and finally C is processed. Compared with the method of using only one CPU core, the parallel processing method of multiple CPUs proposed in this embodiment can reduce the startup time. Specifically, the simultaneous operation of multiple CPU cores can shorten the kernel startup time by 2-3 seconds.

After starting the kernel of the central control panel based on the kernel image, step S270 in FIG. 2 needs to be performed to load the root file system. The root file system is a file system and is the first file system mounted when the kernel is started. The system boot program will load some basic initialization scripts and services into the memory to run after the root file system is mounted, including the boot script, that is, step S280 in Figure 2 runs the boot script, Wherein, if there are multiple boot scripts independent of each other in the boot script, multiple CPUs are used to run the boot scripts in parallel.

Specifically, when there are multiple boot scripts that are independent of each other, when running the boot script, the script can be run in the background, and multiple CPUs can be used to implement multiple boot scripts to run in parallel. Since the processor is multi-core processing servers, running in parallel can reduce startup time. Compared with the way of running the startup scripts one by one, the way of running in parallel in this embodiment can enable multiple processors to run several scripts at the same time, reducing the time for running the startup scripts.

After running the startup script in the background, step S290 in FIG. 2 can be executed to start the first application program, and load one or more driver units. The driver unit is a unit generated after compiling non-essential driver programs. The driver unit It is pre-compiled based on predetermined non-essential drivers.

For some functions other than the auxiliary functions that the driver must obtain through the central control screen when the car is just started, it can correspond to non-essential drivers, such as Ethernet, USB, etc. By compiling the non-essential driver as a driver unit, the driver unit corresponding to the non-essential driver can be loaded after the first application program is started. Compared with the current method, all the driver units are initialized during the process of loading the kernel, and some driver units, such as the Ethernet PHY chip driver, take a long time to load, and there are functions provided by some drivers that are not the first application Therefore, the method provided by this embodiment can compile non-essential drivers into drive units, and delay loading of these drive units can speed up the startup speed.

The driver unit is pre-compiled. Compared with compiling into the image, it takes longer to start the kernel. Compiling it as a driver unit does not consume the startup time of starting the kernel. You can load the driver unit after the kernel is started, which is quite Because of the shortened kernel startup time, the first application can be started faster.

In one embodiment, when starting the kernel of the central control screen based on the kernel image, the key log data can be identified when starting the kernel, wherein, when the key log data is identified, it can be identified that can indicate the cause of the system startup failure log data, because the log data is only useful when analyzing failures, therefore, other logs are redundant except for the reasons for system startup failures, so delete other log data except key log data, Startup time can be reduced. Compared with enabling the kernel log function without deleting redundant log data, the method proposed in this embodiment can shorten the kernel startup time, specifically, the kernel startup time can be shortened by about 3-5 seconds.

This embodiment provides a method for starting the central control panel of a car. During the process of starting the central control panel of the car, the compressed kernel image is loaded to reduce the occupation of the image space, and the compressed kernel image is decompressed to obtain Kernel image, based on the kernel image to start the kernel of the central control panel, including one or more necessary drivers in the kernel, only the necessary drivers are started, reducing the startup time required for the startup of non-essential drivers, and realizing the car's central control The start-up time of the screen is significantly reduced, which can better meet the driver's demand for the use of the car's central control screen.
