Description

Technical Field

[0001] The present application relates to the field of computer management technology, for example, to a notebook out-of-band management method, device, equipment and storage medium based on a domestic single-chip microcomputer. Background Art

[0002] Laptop platforms generally use EC (Embedded Controller) to manage low-speed peripherals of laptops. EC is connected to the CPU through the LPC bus. EC mainly connects various peripherals such as keyboards, batteries, temperature sensors, touchpads, buttons, LED lights, fans, etc., and realizes basic functions such as timing control, battery charge and discharge management, button scanning, LED control, etc., enriching the use characteristics of laptops. It is generally implemented using dedicated chips.

[0003] Domestic MCU is basically the same as EC peripherals, and can realize the management of laptop peripherals. However, domestic MCU has no LPC interface and cannot communicate directly with CPU. Domestic MCU can convert the data sent to the host into I2C data and send it to CPLD. CPLD forwards it to CPU through LPC, that is, CPLD realizes LPC to I2C interface.

[0004] Out-of-band management technology is generally used in server products. It refers to monitoring, configuring and controlling the server through a dedicated management channel when the server is operating normally, without relying on the server's main operating system. Out-of-band management can monitor the status of networked devices through the network. This technology is also applicable to notebook products, but notebooks have high requirements for power consumption. The use of BMC management chip solutions will increase the power consumption of the entire machine and the shutdown standby power consumption. Similarly, when the adapter is not connected, the lithium battery will be quickly depleted. In addition, existing EC chips do not have network controllers. When the computer is turned off, the outside world cannot obtain notebook-related information through the network, and thus out-of-band management cannot be achieved.

[0005] 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

[0067] The LPC data is parsed through CPLD, and the communication with the microcontroller is achieved through I2C to realize the LPC-I2C bridge, which is compatible with the EC software and hardware system.

A switching chip is added to the MCU network and the CPU network to enable external hosts to access the two internal networks based on IP addresses. The switching function is implemented by the switching chip.

[0078] Figure 2 It is an overall functional block diagram of a traditional EC function implementation provided by an embodiment of the present disclosure, wherein NC is a network controller; Figure 3 This is a functional block diagram of an MCU and a CPLD implementing EC provided by an embodiment of the present disclosure; Figure 4 This is a schematic diagram of an MCU configuration Ethernet process provided by an embodiment of the present disclosure, combined with Figure 2 , Figure 3 as well as Figure 4 ,right Figure 1 The out-of-band management method for laptops based on domestic microcontrollers is further described in the article.

[0079] In a specific example, the out-of-band management method for a laptop based on a domestic single-chip microcomputer provided in the embodiment of the present disclosure can specifically use a domestic single-chip microcomputer and a CPLD to implement basic EC functions, such as power-on control, keyboard scanning, lithium battery management, fan control, etc.

[0080] The network interface is realized by using the network control and PHY chip of the domestic single-chip microcomputer.

[0081] The network interface brought out by the domestic single-chip microcomputer and the network interface brought out by the CPU are connected to the external interface of the whole machine through the switching chip, so that the management network port and the data network port share one physical network port.

[0082] After the laptop is turned on, the domestic single-chip microcomputer completes the initialization of its own network control and loads the corresponding network application services, such as data transmission and reception based on the SNMP protocol.

[0083] Domestic single-chip microcomputers communicate with the remote management terminal in real time through the network to report basic equipment information, operating status, fault alarm information, etc.

[0084] The basic information of the device can be sent to the MCU through the LPC interface under the system, and the MCU forwards it through the network.

[0085] After the laptop is turned off, if there is always power supply from the adapter, the microcontroller and the switching chip can be powered all the time, and the out-of-band management service is not interrupted, providing business continuity.

[0086] After the laptop is turned off, if the adapter is not in place, the microcontroller can disconnect the power supply of the switching chip to further reduce the power consumption of the laptop, and the network service will be disconnected; after the adapter is connected, the switching chip will be powered again to restore the network service.

[0087] Based on this method, out-of-band management of laptop devices can be achieved without significantly increasing the power consumption of the entire device.

[0088] Moreover, the embodiment of the present invention is mainly divided into three parts. First, MCU plus CPLD realizes EC function. Second, the network provided by the single-chip microcomputer is used to realize out-of-band management. Third, a switching chip is used to realize the sharing of physical interfaces of data network and management network.

[0089] The microcontroller is a low-power microcontroller independent of the CPU. It has independent internal flash memory and is responsible for computer power on / off timing control, battery management, keyboard scanning, system temperature and fan speed monitoring, etc. It will continue to run as long as the power is connected.

[0090] The MCU does not have an LPC controller and cannot parse the LPC bus data. It is necessary to parse the LPC data through CPLD and communicate with the MCU through I2C, that is, to realize the LPC-I2C transfer bridge. This can achieve compatibility with the existing EC software and hardware system without changing the operating system. The original EC basic functions are realized by adding MCU and CPLD, and the low power consumption requirements of the notebook platform are met.

[0091] The MCU will run as soon as the laptop is powered on. The MCU will first complete the initialization of its peripheral interfaces, including I2C interface, serial port, GPIO, network, etc. In this patent, the MCU has one more network interface than the EC for out-of-band management, so the MCU needs to initialize and configure its own network controller. The configuration process is as follows.

[0092] Enable the Ethernet clock and configure the MCU clock module to enable the MCU clock and Ethernet transmit / receive clock.

[0093] Configure the communication interface, select the interface mode (MII or RMII), and map the corresponding function pins to the multiplexed functions.

[0094] Wait for the network control reset to complete.

[0095] Get and configure PHY register parameters, and configure the MCU registers to be consistent with the PHY register information according to the mode supported by the external PHY.

[0096] Initialize the Ethernet DMA module for data transmission, reducing the CPU usage of network data transmission and reception.

[0097] Initialize the physical memory space used to store descriptor lists and data cache.

[0098] Enable MAC and DMA modules and start sending and receiving.

[0099] After completing the network configuration, the MCU can perform basic data transmission and reception. At the same time, the MCU can encapsulate the data into protocols to support application layer protocols such as SNMP, and send the data collected by the MCU to an external management host through the network.

[0100] In order to support the management network port and the data network port sharing one physical network port, a switching chip is added behind the MCU network and the CPU network to enable the external host to access the two internal networks based on the IP address. The switching function is realized by the switching chip.

[0101] Compared with the BMC solution used in the server platform, this solution has further reduced power consumption and is suitable for out-of-band management on the notebook platform. When only the lithium battery is powered and the computer is turned off, the power supply of the external port of the switch chip microcontroller can be turned off to achieve the same power consumption as EC. After AC is connected, it will automatically wake up and re-power the switch chip and the external port of the microcontroller to meet the needs of out-of-band management.

[0102] and Figure 1 Corresponding to the out-of-band management method for a notebook based on a domestic single-chip microcomputer, the present disclosure also provides an out-of-band management device for a notebook based on a domestic single-chip microcomputer, such as Figure 5 As shown, the device may specifically include:

[0104] The network interface realization module 502 is used to realize the network interface based on the network control and PHY chip of the single-chip microcomputer;

[0105] The external interface realization module 503 is used to connect the network interface of the single-chip microcomputer and the network interface of the CPU, and to bring out the external interface of the whole machine through the switching chip, so that the management network port and the data network port share one physical network port.

[0106] In some embodiments, after the notebook is turned on, the single-chip microcomputer completes the initialization of its own network control and loads the corresponding network application service.

[0107] In some embodiments, the single-chip microcomputer communicates with the remote management terminal in real time through the network to report basic device information, operating status and fault alarm information, wherein the basic device information is sent to the single-chip microcomputer through the LPC interface in the system, and the single-chip microcomputer forwards it through the network.

[0108] In some embodiments, after the laptop is turned off, if the adapter is always powered, the microcontroller and the switch chip are always powered, and the out-of-band management service is not interrupted to ensure business continuity.

[0109] In some embodiments, after the laptop is turned off, if the adapter is not in place, the microcontroller disconnects the power supply of the switching chip to further reduce the power consumption of the laptop, and the network service is disconnected; after the access adapter is connected, the switching chip is powered again and the network service is restored.

[0110] In some embodiments, the EC functions including power-on control, keyboard scanning, lithium battery management, and fan control based on the single-chip microcomputer and CPLD include:

[0111] The LPC data is parsed through CPLD, and the communication with the microcontroller is achieved through I2C to realize the LPC-I2C bridge, which is compatible with the EC software and hardware system. Without changing the operating system, EC functions including power-on control, keyboard scanning, lithium battery management and fan control can be executed.

[0112] In some embodiments, the single-chip microcomputer can also initialize and configure its own network controller;

[0113] The initialization configuration includes: enabling the Ethernet clock, configuring the MCU clock module to enable the MCU clock and the Ethernet transmit / receive clock;

[0114] Configure the communication interface, select the interface mode MII or RMII, and map the corresponding functions to the multiplexed functions;

[0115] Wait for the network control reset to complete;

[0118] Initialize the physical memory space used to store the descriptor list and data cache;

[0119] Enable MAC and DMA modules and start sending and receiving;

[0120] After completing the network configuration, the MCU performs basic data transmission and reception, and at the same time performs protocol encapsulation on the data to support the SNMP application layer protocol, and sends the data collected by the MCU to the external management host through the network;

[0121] The management network port and the data network port share a physical network port. A switching chip is added to the MCU network and the CPU network to enable external hosts to access the two internal networks based on IP addresses. The switching function is implemented by the switching chip.
