Description
Technical Field
The invention relates to the technical field of communication, in particular to an intelligent television and a system starting method thereof.
Background
In the prior art, in order to increase the ac booting speed of the terminal device, a technology of sleeping to a hard Disk (STD) is usually adopted, that is, a system running state before standby is made into an STD mirror image (i.e., a system state mirror image) and stored in an Embedded Multimedia Card (EMMC) of a nonvolatile memory, and after the terminal device is booted, the system state mirror image is read from the EMMC, and then decompressed, skipped and run.
Although the alternating current starting speed of the terminal equipment can be increased by adopting the STD technology, the system running state needs to be made into a system state mirror image and stored in the EMMC before alternating current is cut off every time, so that the shutdown speed is reduced and the service life of the EMMC is prolonged.
In order to overcome the drawback that a system state image is required to be generated before each ac power failure, a starting method using a unique system image is proposed in the industry. However, this method also has drawbacks because, after each boot-up, the file system data stored in the partition in the EMMC is read, written, and deleted by the service or process running in the system based on the synchronization mechanism. And the starting scheme of the unique system mirror image only starts the process of making the mirror image to make the unique system mirror image before the first alternating current power-off after each time of whole system upgrading or over-the-air downloading upgrading. Therefore, after the first complete machine system upgrade or the second alternating current power failure after the over-the-air upgrade, the data in the only system mirror image is not updated any more, the same mirror image data is loaded every time, but the data in the memory may be modified in the system operation process, and the modified data in the memory is synchronized to the EMMC based on the system data synchronization mechanism, so that the loaded mirror image data and the data of the same type stored in the EMMC are different when the system is restarted, the data of the two are not matched, and the partition is mounted to be read only after the device kernel detects the abnormality, thereby causing the alternating current startup failure.
Therefore, on the basis of ensuring the starting speed, a solution to the problem of failure of communication starting of the terminal equipment caused by mismatching of the file system data stored in the EMMC and the unique system mirror image data is needed.

Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present application, are given by way of illustration and explanation only, and are not intended to limit the present application.
It should be noted that the terms "first" and "second" in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
The method provided by the embodiment of the application can be executed by a corresponding device, and the device can be an application program built in a terminal. The terminal can be an intelligent television, a computer and other electrical equipment with the function of starting the system after alternating current electrification, and the type of the equipment is not limited by the application. The following description will be described, without particular mention, with reference to a smart tv, the described solution being equally applicable to other types of devices.
Fig. 1 schematically shows a structural diagram of an intelligent television suitable for the embodiment of the present application. As shown in fig. 1, the terminal includes a nonvolatile Memory 101, a central processing unit 102, and a Double Synchronous Random Access Memory (DDR) 103 (i.e., a Memory). The nonvolatile Memory 101 may be a Read Only Memory (ROM), a Flash Memory (Flash), or an EMMC or other Memory capable of storing data after power failure, which is not limited herein.
The nonvolatile memory 101 is characterized in that data can be stored after power failure, for management convenience, the operating system may divide the nonvolatile memory 101 into a plurality of partitions, and different partitions are used for storing different data, including user data and a unique system image of the operating system. For management and read-write convenience, these partitions may be formatted into a specific file system, such as an EXT4 file system that may be used by terminals based on Linux systems.
The DDR 103 has stored therein computer program instructions, including operating system program instructions. Taking the operating system program instruction as an example, the operating system program instruction is executed by taking a system process as a basic execution entity in a running state, and may include types such as a user process, a kernel process and the like.
Based on the above terminal, after the ac power-on, the cpu 102 loads the unique system image stored in the non-volatile memory into the ddr sdram 103 during the system boot process.
The unique system image stored in the non-volatile memory 101 is used to specifically describe the operating state of the system, and after the system is powered on, the system process restores the operating state of the system according to the data in the unique system image. And the data in the unique system mirror image is updated only before the AC power-off after the whole system is upgraded or the over-the-air downloading is upgraded, and specifically, a scheduling process in the kernel process sends a mirror image making instruction to update the data in the unique system mirror image.
As shown in fig. 2, a flowchart of a system startup method of an intelligent television according to an embodiment of the present application may be implemented by a system startup device of the intelligent television.
The method comprises the following steps:
s201: freezing a system process for accessing a first partition in a memory; the system process comprises a user process and a kernel process, and the user process comprises a data synchronization process.
In practical application, the method can further comprise the following steps before the steps: after the alternating current is electrified, a starting program of the system guides internal software to initialize the hardware equipment; after the hardware equipment is initialized, the kernel is started and initializes each subsystem, thereby bringing the software and hardware environment of the system to a proper state.
In S201, a system process that has a possibility of accessing the first partition in the memory may be frozen. By adopting the traditional mirror image loading method, after the only system mirror image is loaded to the memory, the set partition in the memory is a readable and writable partition, and data in the partition is possibly not matched with data in a corresponding area in the nonvolatile memory. The configured partitions in the memory may include, but are not limited to, partitions such as a user data partition (for storing user data) and a Tvconfig partition (for storing device configuration information) in a Linux system.
For convenience of description, the memory partition with data mismatch caused by unique system image loading is referred to as a first partition, and the partition on the nonvolatile memory corresponding to the first partition (i.e., the nonvolatile memory partition mounted on the first partition) is referred to as a second partition. The first partition and the second partition are both readable and writable partitions. The first partition and the second partition may be one or more partitions, respectively. For example, taking a Linux system as an example, a first partition in the memory may include a Userdata partition (for storing user data) and a Tvconfig partition (for storing device configuration information), and accordingly, a second partition in the nonvolatile memory includes the Userdata partition and the Tvconfig partition.
The states of the system process mainly include an executable state, an interruptible sleep state, an uninterruptable sleep state, a suspended state, and an exit state. In S201, a kernel process and a user process that may access the first partition in the memory, such as a scheduling process and a data synchronization process that send a unique system image making instruction, may be frozen by setting the state of the system process that may access the first partition in the memory to an uninterruptible sleep state. Because the user processes and the kernel process are frozen before the unique system image is loaded, the frozen user processes and the kernel process cannot run in the unique system image loading process, and therefore the problem that the system cannot be normally started due to the fact that the data of the memory is not matched with the data stored in the nonvolatile memory after the user processes and the kernel process find that the unique system image is loaded to the memory in the unique system image loading process can be solved.
S202: triggering the process for unique system image loading so that the process for unique system image loading reads the unique system image from the non-volatile storage and loads the unique system image to the memory.
In some embodiments, to save storage space, the unique system image is compressed and stored in the non-volatile memory, and for this case, in S202, the process for loading the unique system image reads the compressed unique system image stored in the non-volatile memory, decompresses the compressed unique system image, and loads the data of the decompressed unique system image into the memory.
S203: unfreezing the data synchronization process, so that the data synchronization process synchronizes data in a second partition corresponding to the first partition in the nonvolatile memory to the first partition.
Optionally, the data synchronization may be implemented by unloading and then re-mounting. In loading the unique system image into the memory, the partition in the non-volatile storage needs to be mounted to the corresponding partition in the memory. Such as mounting a user data partition in non-volatile storage to a user data partition in memory. For the partition of the nonvolatile memory and the corresponding memory partition with unmatched data caused by the unique system mirror image loading, the data synchronization can be realized in a mode of unloading firstly and then re-mounting.
The process of implementing data synchronization by means of first unloading and then re-mounting may include: the data synchronization process unloads the second partition of the non-volatile storage from the first partition of the memory and re-mounts the second partition of the non-volatile storage to the first partition of the memory, such that data in the second partition is synchronized to the first partition.
S204: and after the data in the nonvolatile memory is synchronized to the memory by the data synchronization process, unfreezing other frozen system processes.
Alternatively, these system processes may be unfrozen by setting the state of the frozen other user processes and the frozen kernel process to an executable state. The unfrozen kernel process comprises a scheduling process, and the scheduling process can schedule other system processes to complete the subsequent system starting process.
Since the system is started based on the unique system image, which is done under the control of the scheduling process in the kernel process, the scheduling process is first defrosted after the data in the second partition is fully synchronized to the first partition. Then the scheduling process sends instructions to the frozen other user processes and the frozen other kernel processes, so that the frozen other user processes and the frozen other kernel processes continue to process, and system starting is completed.
According to the above flow, since the user process and the kernel process which may access the first partition in the memory are frozen before the unique system image is loaded, in the unique system image loading process, the frozen user process and the kernel process cannot run, so that the problem that the system cannot be normally started due to the fact that the user process and the kernel process find that the data of the memory where the unique system image is loaded is not matched with the data stored in the nonvolatile memory in the unique system image loading process is avoided. After the unique system image is loaded to the memory, the data synchronization process in the user process is unfrozen, so that the data synchronization process synchronizes the data stored in the nonvolatile memory to the memory, and then unfreezes other frozen processes.
In order to more clearly understand the embodiment of the present application, a system starting process is described below by taking an intelligent television based on an Android system as an example.
Wherein, the subregion in the nonvolatile memory of intelligent TV set includes:
a System partition (System partition) for storing a System running state image;
a Userdata partition (user data partition) for storing user data, such as application programs installed by the storage system;
a Booting partition (boot partition) for storing a Linux kernel and a virtual memory (ramdisk) partition;
the Tvconfig partition (configuration information partition) is a partition for storing related data of the smart television, and may include volume, channel, screen parameter, power amplifier parameter, and the like.
In the above partitions, the Userdata partition and the Tvconfig partition are readable and writable partitions, and need to be synchronized during system startup; the System partition and the Booting partition are read-only partitions, and data synchronization is not needed in System starting.
It should be noted that, in the embodiment of the present application, only a part of the partitions involved in the system boot is listed for describing the system boot process, and other partitions are not listed here one by one, and the present application is not limited to this.
As shown in fig. 3, an embodiment of the application provides a flowchart of system startup of an intelligent television based on an Android system.
After the smart television is powered on by alternating current, a system starting process of the smart television can include:
s301: a Bootloader process is performed.
After the intelligent television is electrified in an alternating-current mode, a boot program bootrom in the central processing unit guides Bootloader software located on the nonvolatile memory. Bootloader software initializes hardware equipment and establishes a memory space mapping diagram, so that the software and hardware environment of the system is brought to a proper state, for example, Bootloader software initializes modules such as a necessary clock, a necessary serial port and a necessary memory. Copying the linux kernel mirror image of the nonvolatile memory into the memory, then finishing the life cycle of the Bootloader in the system starting process, jumping to the beginning of the linux kernel, and further executing the flow from S302 to S308 in FIG. 3.
S302: and initializing each subsystem by the Linux kernel.
After the hardware equipment is initialized, initializing each subsystem by the Linux kernel, wherein the subsystems comprise a memory management subsystem, a power management subsystem, a universal serial bus subsystem, an input subsystem and the like.
S303: the system process is frozen.
In the Linux system, in order to limit the access capability between different processes and prevent the processes from randomly acquiring data in a memory partition or acquiring data of peripheral equipment, the running state of one process is divided into a kernel state and a user state. When the core state is in, the central processing unit can access all data in the memory, including peripheral devices such as a nonvolatile memory and a network card, and in this state, the central processing unit can also switch one program to another program; when the CPU is in the user mode, the CPU can only access part of data in the memory in a limited way, and the CPU is not allowed to access the peripheral equipment.
In S303, at the later stage of initialization of each subsystem, the system process is in a kernel state, and the state of the system process that may access the partition of the memory where the unique STD image is decompressed is an uninterruptible sleep state by calling a freeze-process function, where the frozen system process is not scheduled. The frozen system process comprises a user process and a kernel process, the user process comprises a Histd process used for data synchronization, and the kernel process comprises an StdService process used for sending a unique STD mirror image making instruction.
S304: the process for unique STD image loading is started.
In the above steps, the process for unique STD image loading is started. And enabling the process to read the unique STD mirror image of the nonvolatile memory, load the unique STD mirror image into a Booting partition in the nonvolatile memory, decompress the compressed unique system mirror image, and copy the decompressed unique system mirror image data into the memory by taking a page (for example, the size of 4K) as a unit.
S305: unfreezing the Histd process. So that the Histd process synchronizes the data in the non-volatile memory to the memory.
Taking the user data Userdata as an example, after copying the Userdata in the unique STD mirror image into the Userdata partition of the partition in the memory where the unique STD mirror image is located by the process for loading the unique STD mirror image, the Userdata partition in the nonvolatile memory is mounted to the Userdata partition of the partition in the memory where the unique STD mirror image is located. After the Histd process is unfrozen, the Histd process unloads data in the Userdata partition of the partition where the unique STD image in the memory is located, and re-mounts the Userdata partition in the nonvolatile memory onto the Userdata partition of the partition where the unique STD image in the memory is located, namely, scanning and copying of differential data are completed through loading and unloading operations of the partitions, so that the data in the Userdata partition in the nonvolatile memory is synchronized to the Userdata partition of the partition where the unique STD image in the memory is located.
S306: and judging whether the data synchronization is finished. If the data synchronization is completed, executing step S307, and if the data synchronization is not completed, waiting for the Histd process to complete the data synchronization.
S307: and unfreezing the StdService process. After the data synchronization in the Userdata partition in the memory is completed, the StdService process is firstly unfrozen.
S308: the StdService process unfreezes the frozen other system processes. The StdService process sends an instruction to the frozen other system process, unfreezes the frozen other system process, and triggers the frozen other system process to start working.
At S309, the thawed system process recovers the running state of the Android system according to the synchronized data, thereby implementing starting of the Android system.
