Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The software shutdown method of the VxWorks operating system is applicable to the application scene shown in FIG. 1a, and comprises an application layer shutdown module 102, an operating system layer shutdown module 104 and a bottom hardware shutdown module 106, wherein the application layer shutdown module 102 is a software shutdown inlet and provides a shutdown operation interface for a user to realize a shutdown command, the operating system layer shutdown module 104 provides a function interface to realize application program shutdown notification, and the functions of closing an active peripheral device through a peripheral device driver, stopping system services and components and the like are realized, the bottom hardware shutdown module 106 provides a core interface related to ACPI and shutdown, and operates a related hardware register to enable hardware to enter an S3 state. When the user executes the shutdown operation, the function provided by the application layer shutdown module 102 is called, the function enters the operating system layer shutdown module 104, and finally the shutdown of the motherboard is completed through the bottom layer hardware shutdown module 106. The application data and the system level cache data can be stored in time, and the damage probability of hardware peripherals is reduced.
Referring to fig. 1b, the software shutdown method for the VxWorks operating system provided by the present invention is applicable to a computer, and the computer includes a motherboard 101, an I/O device 103, and a hard disk 105, where the motherboard 101 runs the application layer shutdown module, the operating system layer shutdown module, and the bottom layer hardware shutdown module, where the I/O device 103 may specifically be a keyboard, a mouse, a scanner, a display, and the like, and the hard disk 105 may specifically be a Solid State Disk (SSD), a mechanical hard disk (HDD), a hybrid hard disk, and the like. The I/O device 103 is connected to the bus via an interface, the I/O device 103 receiving address information from the address bus, deriving control signals from the control bus, and connecting to other components via a data bus. The bus is an internal structure of computer, it is a public channel for transferring information by CPU, internal memory, input and output devices, all the components of computer are connected by means of bus, and the external device is connected with bus by means of correspondent interface circuit to make data interaction. When shutdown operation is performed on the I/O device 103, the I/O device 103 is connected to the motherboard 101 through a data bus, enters an application layer shutdown module, which is a software shutdown entry to provide a shutdown operation interface for the user, then enters an operating system layer shutdown module, shuts down the active hard disk 105 through a peripheral driver, stops functions such as system services and components, and finally jumps to a bottom layer hardware shutdown module, operates a related hardware register, causes the hardware to enter an S3 state, and finally completes shutdown of the motherboard 101. Therefore, the application data and the system level cache data can be stored in time, and the damage probability of the hardware peripheral is reduced.
As shown in fig. 2, an embodiment of the present invention provides a software shutdown method for a VxWorks operating system, including:
The shutdown registration command is used to trigger the application layer shutdown module to execute a shutdown operation, and may be a code segment such as a character string written by a user or a shutdown registration command formed by a trigger peripheral, for example, the shutdown registration command may be issued by continuously pressing a power key for 1 minute.
When the computer is shut down, a user sends a shutdown registration command to the VxWorks operating system, and then the shutdown registration command is executed by a VxWorks shell (VxWorks kernel) to enter an operating system layer shutdown module.
In some embodiments, the VxWorks operating system may provide a user with a friendly UI interface so that the user enters a shutdown registration command on the UI interface, which the VxWorks operating system then obtains.
As shown in fig. 3, when entering the shutdown module of the operating system layer, the VxWorks operating system restarts the system according to the shutdown registration command, for example, the VxWorks operating system notifies the system service and the application program to execute a restart operation, where the restart operation includes: resetting the network, shutting down the peripheral, refreshing the cache, and notifying the system that a reset is to occur.
In the traditional technology, when shutdown operation needs to be performed on the VxWorks operating system, the traditional VxWorks operating system does not support software shutdown, so that the traditional VxWorks operating system can only be powered off through hardware, namely, a user directly unplugs a main board power supply in the VxWorks operating system to achieve power-off shutdown. For example, upon power failure, the cached data in the memory is immediately lost and cannot be timely saved to an external storage device (e.g., a hard disk), which results in data loss. Moreover, if the mechanical hard disk is in a working state, the power is suddenly cut off, which causes the damage of the mechanical hard disk and the like, and the stable and reliable operation of the system is seriously influenced.
Therefore, the conventional techniques have at least the following problems:
1. the application program cannot perceive that the VxWorks operating system is about to be shut down and loses application level data.
Many applications cannot know that the system is going to be shut down and cannot perform relevant processing, such as saving application data, issuing an alarm, logging, and the like.
2. System level cache data is lost.
The VxWorks operating system needs to cache data in the memory, and by adopting the simple rough shutdown mode, a CPU of the VxWorks operating system cannot refresh the data in the memory to an external storage device (such as a hard disk) in time.
3. The probability of damaging the hardware peripheral is increased.
For example, such a shutdown mode may cause damage to the mechanical hard disk while the mechanical hard disk is in operation.
In this embodiment, before shutdown, some application programs or system services in the system can save the application data and the system level cache data in time by restarting the system, so that safe shutdown is realized.
In some embodiments, when restarting the system, the VxWorks operating system executes a reboot function according to the shutdown registration command to notify the system service and the application program to execute a restart operation. The reboot function can ensure that the restarting function of the operating system level is normal, then reset the system network, namely, the VxWorks operating system returns to the initial state, then close the peripheral equipment, namely close the active peripheral equipment through the peripheral equipment driving program, then refresh the cache, secondly inform that the VxWorks operating system is about to be reset, through resetting the specific functional unit, the network function is ensured to normally stop working from the system level, the system cache is reliably refreshed, the system service and the application program can sense that the operating system is about to be restarted and correspondingly process the VxWorks operating system, for example, the application program can timely store important data in a hard disk after receiving the notice that the VxWorks operating system is about to be restarted.
When the VxWorks operating system is restarted, the VxWorks operating system generates a system shutdown instruction, and the system shutdown instruction is used for indicating that bottom hardware works in a shutdown state.
In some embodiments, the system shutdown instruction may be an instruction for calling another function in the process of executing the reboot function, and the other function is used for assisting the reboot function to reliably and stably shutdown the VxWorks operating system. For example, the other function is the sysToMonitor function, which is a function highly related to specific hardware and located in the board-level support package, and the user can modify the function according to the actual hardware, and the specific function of the function is to close the interrupt and jump to the entry of the VxWorks operating system.
And step 206, controlling the bottom layer hardware to work in a shutdown state according to the system shutdown instruction.
After jumping to the entrance of the VxWorks operating system, the VxWorks operating system polls the working state of each bottom hardware according to a system shutdown instruction, and if the working state of the bottom hardware is 'working', the VxWorks operating system sends a hardware shutdown instruction to the bottom hardware to indicate the bottom hardware to be shut down. And if the working state of the bottom hardware is 'shutdown', the VxWorks operating system does not send a hardware shutdown instruction to the bottom hardware, and the current shutdown state of the bottom hardware is maintained.
In some embodiments, the VxWorks operating system may directly send a hardware shutdown instruction to all bottom-layer hardware without polling the operating states of the bottom-layer hardware one by one, so that the corresponding bottom-layer hardware is shutdown.
In some embodiments, in the process of controlling the bottom-layer hardware to work in the shutdown state, the VxWorks operating system closes the interrupt service according to the generated system shutdown instruction. And after the interrupt service is closed, sending a hardware shutdown instruction to the bottom layer hardware so as to enable the bottom layer hardware to work in a shutdown state. Therefore, before jumping to the bottom hardware shutdown module, the VxWorks operating system firstly closes the interrupt service, so that the subsequent shutdown of the bottom hardware can be indicated more stably and reliably, and the shutdown low working efficiency caused by the disturbance of other high-priority interrupts is avoided.
In some embodiments, the VxWorks operating system executes the systomultitor function according to a system shutdown instruction to close the interrupt service. Since the sysToMonitor function can be modified according to the actual hardware, in this embodiment, the sysToMonitor function is modified to have the function of closing the interrupt and jumping to the bottom hardware shutdown module.
As shown in fig. 4, specifically, a reboot function is executed first, which can ensure that the restart function of the operating system is normal, the system network is reset, that is, the system returns to an initial state, then the peripheral device is closed, that is, the active peripheral device is closed by the peripheral device driver, then the cache is refreshed, next the system is notified to be reset, after the systonometer function is closed and interrupted, the system jumps to a bottom hardware shutdown module, and a hardware shutdown instruction is sent to the bottom hardware, so that the bottom hardware works in a shutdown state. The bottom hardware shutdown module provides an ACPI (advanced peripheral interface) and shutdown related core interface, operates related hardware registers, enables the hardware to enter an S3 state, suspends the hardware into a memory in an S3 state, and stores working data of the system before the system enters the S3 state into the memory.
In some embodiments, the underlying hardware includes various types of peripherals, such as power supplies, hard disks, memory, displays, power amplifiers, and so forth.
Generally speaking, by acquiring a shutdown registration command, restarting the system and generating a system shutdown command according to the shutdown registration command, and controlling the bottom layer hardware to work in a shutdown state according to the system shutdown command, on one hand, the shutdown reliability can be improved, and the damage probability of the hardware peripheral equipment can be reduced. On the other hand, before shutdown, the system can be restarted, so that some application programs or system services in the system can store application data and system level cache data in time, and safe shutdown is realized.
In an embodiment, in the software shutdown method of the VxWorks operating system, as shown in fig. 5, bottom-layer hardware includes a power supply, and when the power supply is controlled to operate in a shutdown state, the VxWorks operating system sends a power supply shutdown instruction to the power supply, so that the power supply is shut down according to the power supply shutdown instruction. In some embodiments, the power shutdown instruction may be an instruction that follows a power shutdown protocol.
In some embodiments, the power supply is an ATX power supply, which functions to convert 220V AC power to 5V, 12V, 3.3V DC power for use inside the computer. The ATX power is controlled by the PSON signal, and when the PSON signal is low, i.e. the power shutdown command is the PSON signal of low level, the ATX power stops supplying power to the X86 motherboard, and the X86 motherboard is powered off and shutdown accordingly. The south bridge SLP _ S3 is set on the X86 mainboard, the pin of SLP _ S3 is connected to the PSON pin of ATX power supply, the south bridge of the X86 CPU is set with relevant register to control the signal of SLP _ S3 pin, as long as the corresponding level is output on SLP _ S3 pin to make PSON low, the ATX power supply will stop supplying power to the X86 mainboard, and the X86 mainboard will be powered off and shut down. In other embodiments, the pin on the X86 motherboard may be GPIO0, the pin of GPIO0 is connected to the PSON pin of the ATX power supply, and the south bridge of the X86 cpu is provided with a related register to control the signal of the GPIO0 pin, so that as long as the corresponding level is output on the GPIO0 pin to make the PSON low, the ATX power supply will stop supplying power to the X86 motherboard, and the X86 motherboard will be powered off and shut down accordingly.
