[0001] The present application relates to the technical field of server security control, for example, to a mobile server power button soft switch method and storage medium. Background Art

[0002] There are generally two application scenarios for servers. The first application scenario is the traditional data center, where server equipment is deployed in a computer room environment with constant temperature and humidity, and servers are generally connected to the Internet, mainly for Internet services, providing users with shopping websites, email management, database processing, game access and other services. Server equipment needs to work continuously and stably 24*7 hours a day in order to provide uninterrupted services to the outside world. Another application scenario is a mobile data center, where server equipment is installed in mobile environments such as vehicles, ships, and aircraft.

In mobile environments such as vehicles, ships, and aircraft, space is limited, and server equipment is generally not equipped with a display and keyboard and mouse, and cannot implement soft shutdown operations under the operating system.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application. Summary of the invention

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The present disclosure provides a method for soft switching a power button of a mobile server, the method comprising:

[0006] The power-on control chip is connected to the CPU through a serial port or a GPIO interface to form a shutdown command line issuing link, which notifies the shutdown monitoring service software running in the operating system. The shutdown monitoring service software executes the shutdown command and notifies the operating system to perform the shutdown operation.

[0007] After the operating system completes the shutdown operation, it sends a shutdown completion signal to the power-on control chip, and the power-on control chip performs a power-off operation.

[0008] In some embodiments, the method further comprises:

[0009] If the power-on control chip does not detect the shutdown completion signal within the first preset time period, the power-on control chip directly cuts off the power supply to perform a hard shutdown operation.

[0010] In some embodiments, the power-on control chip is connected to the CPU through a serial port or a GPIO interface to form a shutdown command line issuing link, and notifies the shutdown monitoring service software running in the operating system. The shutdown monitoring service software executes the shutdown command and notifies the operating system to perform the shutdown operation, including:

[0011] After receiving the external shutdown signal, the MCU / CPLD sends a shutdown command "0xff0x050x500xfe" to the operating system through the serial port or GPIO interface connected to the CPU. The operating system returns the "0xff0x050x500xfe" data within the second preset time period, indicating that the system is working normally, and notifies the operating system to perform the shutdown operation.

[0012] In some embodiments, after the operating system completes the shutdown operation, it sends a shutdown completion signal to the power-on control chip, and the power-on control chip performs a power-off operation; if the power-on control chip does not detect the shutdown completion signal within a first preset time period, the power-on control chip directly cuts off the power supply to perform a hard shutdown operation, including:

[0013] After the operating system completes the shutdown operation, it sends a shutdown completion signal to the MCU / CPLD. After receiving the data returned by the system, the MCU / CPLD starts a timeout. If no soft shutdown signal sent by the system is received within the first preset time period, a power-off hard shutdown is performed; if the operating system does not return the "0xff0x050x500xfe" data within the third preset time period, it indicates that the system is working abnormally and a hard shutdown is performed directly.

[0014] In some embodiments, the method further comprises:

[0015] The shutdown monitoring service software runs in the operating system. The shutdown monitoring service software monitors the serial port communication in real time. When receiving the shutdown command sent by the MCU / CPLD, the same command data is returned to the MCU / CPLD through the GPIO or serial port, and then the shutdown command is executed to perform a soft shutdown.

[0016] In some embodiments, the method further comprises:

[0017] The server device is turned on when the power button signal is pressed;

[0018] If the server device power button is not pressed, the BMC cannot be turned on.

[0019] In some embodiments, the method further comprises:

[0020] After receiving the shutdown signal from the BMC interface or the server device power button, the MCU / CPLD uploads the shutdown signal to the operating system, and the operating system monitoring script detects and executes the shutdown.

[0039] Figure 1 The present invention is a flowchart of a soft-switch method for a power button of a mobile server provided by an embodiment of the present invention.

[0040] like Figure 1 As shown, the mobile server power button soft switch method may include:

[0041] S01, the power-on control chip is connected to the CPU through the serial port or GPIO interface to form a shutdown command line issuing link, and the shutdown monitoring service software running in the operating system is notified. The shutdown monitoring service software executes the shutdown command and notifies the operating system to perform the shutdown operation;

[0042] S02, after completing the shutdown operation, the operating system sends a shutdown completion signal to the power-on control chip, and the power-on control chip performs a power-off operation.

[0043] Figure 2 is a block diagram of a soft shutdown system provided by an embodiment of the present disclosure, Figure 3 is a MCU / CPLD logic block diagram provided by an embodiment of the present disclosure, Figure 4 is a schematic diagram of a serial communication setting provided by an embodiment of the present disclosure, Figure 5 This is a schematic diagram of a code corresponding to a one-key shutdown signal provided by an embodiment of the present disclosure, combined with Figures 2 to 5 ,right Figure 1 The soft switching method of the power button of the mobile server is further described.

[0044] In some embodiments, Figure 1 The method may also include:

[0045] If the power-on control chip does not detect the shutdown completion signal within the first preset time period, the power-on control chip directly cuts off the power supply to perform a hard shutdown operation. The first preset time period may be 60 seconds, and may also be adjusted according to actual conditions.

[0046] In some embodiments, the power-on control chip is connected to the CPU through a serial port or a GPIO interface to form a shutdown command line issuing link, and notifies the shutdown monitoring service software running in the operating system. The shutdown monitoring service software executes the shutdown command and notifies the operating system to perform the shutdown operation, including:

[0047] After receiving the external shutdown signal, the MCU / CPLD sends a shutdown command "0xff0x050x500xfe" to the operating system through the serial port or GPIO interface connected to the CPU. The operating system returns "0xff0x050x500xfe" data within the second preset time period, indicating that the system is working normally, and notifies the operating system to perform the shutdown operation. The second preset time period can be specifically 5s, and can also be adjusted according to actual conditions.

[0048] In some embodiments, after the operating system completes the shutdown operation, it sends a shutdown completion signal to the power-on control chip, and the power-on control chip performs a power-off operation; if the power-on control chip does not detect the shutdown completion signal within a first preset time period, the power-on control chip directly cuts off the power supply to perform a hard shutdown operation, including:

[0049] After the operating system completes the shutdown operation, it sends a shutdown completion signal to the MCU / CPLD. After receiving the system return data, the MCU / CPLD performs a timeout. If the soft shutdown signal sent by the system is not received within the first preset time period, a power-off hard shutdown is performed; if the operating system does not return the "0xff0x050x500xfe" data within the third preset time period, it indicates that the system is working abnormally, and a hard shutdown is performed directly. The third preset time period can be specifically 10s, and can also be adjusted according to actual conditions.

[0050] In some embodiments, Figure 1 The method may also include:

[0051] The shutdown monitoring service software runs in the operating system. The shutdown monitoring service software monitors the serial port communication in real time. When receiving the shutdown command sent by the MCU / CPLD, the same command data is returned to the MCU / CPLD through the GPIO or serial port, and then the shutdown command is executed to perform a soft shutdown.

[0052] In some embodiments, Figure 1 The method may also include:

[0053] The server device is turned on when the power button signal is pressed;

[0054] If the server device power button is not pressed, the BMC cannot be turned on.

[0055] In some embodiments, Figure 1 The method may also include:

[0056] After receiving the shutdown signal from the BMC interface or the server device power button, the MCU / CPLD uploads the shutdown signal to the operating system, and the operating system monitoring script detects and executes the shutdown.

[0057] In a specific example, drawing on the experience of a project where the server equipment was forced to power off and shut down at the customer's site, and the hard disk system was damaged, in the firmware design of the server equipment, the power switch was designed and implemented with the embedded firmware and system driver to soft shut down the power button, greatly improving the reliability and flexibility of the server equipment.

[0058] The hard shutdown process is that the MCU / CPLD directly performs a power-off operation. The soft shutdown process is that the power-on control chip (CPLD or MCU, etc.) is connected to the CPU through a serial port or GPIO interface to form a shutdown command line issuance link, notifying the shutdown monitoring service software running in the operating system. The shutdown monitoring service software executes the poweroff or shutdown command, notifies the operating system to perform a shutdown operation, and at the same time, notifies the power-on control chip that the shutdown command has been received. After the operating system completes the shutdown operation, it sends a shutdown completion signal PWR_CTR0&1 to the power-on control chip, and the power-on control chip performs a power-off operation. If the power-on control chip does not detect the shutdown completion signal PWR_CTR0&1 within 60 seconds, the power-on control chip directly cuts off the power and performs a hard shutdown operation. The shutdown operating system block diagram is as follows: Figure 2 shown.

[0059] There are two types of external shutdown signals: (a) the power button signal on the front panel; (b) the shutdown signal on the BMC interface;

[0060] The soft shutdown solution is: after the MCU / CPLD receives the external shutdown signal, it sends the shutdown command "0xff0x050x500xfe" to the operating system through the serial port connected to the CPU. The operating system returns 0xff0x050x500xfe data within 5 seconds, indicating that the system is working normally. After the MCU / CPLD receives the data returned by the system, it will time out (60 seconds). If it has not received the soft shutdown signal sent by the system after the timeout, it will power off and perform a hard shutdown. If the operating system does not return 0xff0x050x500xfe data within 10 seconds, it means that the system is working abnormally and a hard shutdown is performed directly.

[0061] The shutdown monitoring service software runs in the operating system. The shutdown monitoring service software monitors the serial port communication in real time. When receiving the shutdown command sent by the MCU / CPLD, it returns the same command data to the MCU / CPLD through the GPIO or serial port, and then executes the shutdown command to perform a soft shutdown. The logic block diagram is as follows Figure 3 shown.

[0062] The shutdown signal of the server device power button: when lifted, it is high (shutdown) by default, and when pressed, it is low level.

[0063] Upload shutdown signal (serial port): Serial port communication settings are as follows Figure 4 shown.

[0064] After receiving the one-key soft shutdown signal, the serial port sends 0xff0x050x500xfe data to the operating system. The operating system returns 0xff0x050x500xfe data within 5 seconds, indicating that the system is working normally. After receiving the data, the timeout (15 seconds) begins. If the following soft shutdown signal is not received after the timeout, a hard shutdown is performed. If the operating system does not return 0xff0x050x500xfe data within 5 seconds, it means that the system is working abnormally and a hard shutdown is performed directly.

[0065] Code example:

[0066] / / Send a one-key shutdown signal

[0067] u8 uart3_buff[4]={0xFF,0x05,0x50,0xFE};

[0068] UartSendData(UART3,uart3_buff,4);

[0069] / / Receive the data returned by the operating system

[0070] The code example can be specifically as follows Figure 5 shown.

[0071] Soft shutdown signal: The soft shutdown signal PWR_CTR0&1 sent by the system.

[0072] The server can only be powered on when the power button is pressed. If the button is not pressed, the BMC cannot be powered on. After the CPLD / MCU ​​receives the shutdown signal from the BMC interface and the server power button, it uploads the shutdown signal pin to the operating system, and the monitoring script under the system detects and executes the shutdown.

[0073] In the present disclosure, the specific configuration of the server device soft shutdown resources is shown in Table 1.

[0074] Table 1

[0075]

[0076] The present invention realizes the soft shutdown of the server equipment by pressing the power button. The shutdown monitoring service software unique to the server version operating system can monitor the shutdown signal transmitted by the hardware and provide feedback. In addition, the link between the CPU and the power-on control chip for the transmission of the soft shutdown command is that the CPLD / MCU ​​communicates with the CPU through the serial port, and the transmission is fast and stable with high scalability. In addition to the serial port communication, the shutdown monitoring service software also reserves two communication modes, GPIO and I2C, and the hardware design can be selected according to the actual situation.

[0077] The present disclosure provides a mobile server power button soft switch method, in which the server device meets the application requirements of frequent shutdown of mobile server devices through power button soft shutdown, and also meets the requirements of equipment maintenance shutdown in fixed computer room environments, creating a precedent for server device power button soft shutdown. The shutdown monitoring service software and chip firmware included in the server device power button soft shutdown are all independently developed, controllable and safe; and the solution only needs to lead out an additional serial port or I2C of the CPLD / MCU, without additional hardware design and no additional cost; the server device solves the problem of frequent shutdown of mobile server devices and damages files through the power button soft shutdown function, and also saves the configuration of keyboards and monitors, saves resources, and protects the equipment.

[0078] In addition, the present disclosure has opened up a new method for soft shutdown of server devices by pressing the power button, so that the server device can smoothly trigger the operating system to perform software shutdown operations by pressing the power switch like a computer device. This avoids damage to the operating system files and hard disk of the server device. At the same time, there is no need to connect a monitor and keyboard and mouse, which greatly saves space and cost in a mobile environment.
