Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

At present, the default of the power key functions of most servers in a data center is to realize the power-on and power-off actions of the servers through a GPD3_ PWRBTN _ N signal of a PCH, when the power supply of the servers needs to be powered off, the power key is pressed for a short time to trigger the power-off action, the SCI interrupt triggers a system kernel to perform a soft power-off action, and the power key is pressed for a long time to trigger a hardware power-off action. When the server is in a non-operating System, a power key is pressed for a short time to trigger a System Management interrupt mechanism (SMI) in the BIOS according to a GPD3_ PWRBTN _ N signal, the SMI interrupt mechanism adopts a hardware interrupt mechanism principle, namely a System Management Mode (System Management Mode) that the power key generates hardware interrupt to trigger SMI interrupt in the BIOS when being pressed for a short time, the CPU is required to enter the System Management Mode in advance when an SMM program is executed, a specific operation flow is that the CPU needs a memory area SMRAM, the value of the register is stored in the SMRAM before the CPU enters an SMM, the program is transferred to SMINTRY POINT to be executed, the SMM instruction is used for jumping back to the original SMM to continue to be executed after the SMM program is processed, and the value of the CPU register is restored. And after the server power supply key is pressed for a short time, the SMM program writes a shutdown value to the CPU internal register through the IO port to perform shutdown action.

Currently, an X86 processor or an ARM (Advanced RISC Machine) processor is generally adopted in a server, wherein the X86 processor refers to an instruction set architecture of a central processing unit based on an Intel8086 and backward compatible, and supports the above-mentioned SMI interrupt mechanism. Compared with an X86 processor, the ARM processor has the advantages of multiple cores, small size, low power consumption, low cost, high performance and the like, the business can be processed more efficiently and more quickly, and based on the advantages, the server based on the ARM processor is more and more widely applied. However, due to the small size of the ARM processor, its startup and operation needs to be tied to external SCP firmware. In order to ensure the safe startup of the ARM server, the SCP firmware of the ARM processor needs to be checked safely when the ARM server is started. For the ARM server, the ARM server does not have BIOS firmware and does not support the SMI interrupt type, so the ARM server cannot be powered off by pressing a power key for a short time at present, which causes inconvenience in operation of the ARM server.

In order to solve the problem that the ARM server cannot be powered off by pressing a power key for a short time at present, fig. 1 is a flowchart illustrating steps of a server power supply power-down control method according to an embodiment of the present invention, where the method is applied to an advanced reduced instruction set ARM server, the ARM server includes a microprocessor and a power key, and the method includes the following steps:

Specifically, the ARM server may be provided with a signal acquisition circuit, and the signal acquisition circuit is connected to the power key and is configured to acquire a level signal output by the power key. In the embodiment of the present invention, the signal acquisition circuit may adopt an ADC acquisition circuit, and for example, the model of the ADC acquisition circuit may be LTC2440.

In the using process, the microprocessor is connected with the signal acquisition circuit and used for analyzing the voltage signals acquired by the signal acquisition circuit and judging the using state of the power supply key. The power key may have a high state and a low state, and the monitoring event that the power key is in the pressed state may include: after the power supply key is converted from a high level to a low level, the low level is converted into a high level; or the power supply key is converted from the low level to the high level and then converted from the high level to the low level.

Still be provided with the timer on the ARM server, after confirming that the power button is in the state of pressing, this timer is used for counting the power button and is in the accumulative duration of pressing the state, and the process of calculating the power button and be in the accumulative duration of pressing the state can include: when the power supply key is converted from a high level to a low level, recording the first time when the timer starts to time; after the timer starts to time, when the power supply key is converted from the low level to the high level, the timer finishes timing and records the second time when the timer finishes timing; and calculating the accumulated time length between the first time and the second time. In this embodiment, the preset time threshold may be 3 seconds, when the accumulated duration of the power key being in the pressed state is less than 3 seconds, the power key is considered to be in the short-press state, and when the accumulated duration of the power key being in the pressed state is greater than or equal to 3 seconds, the power key is considered to be in the long-press state. It should be noted that, generally, the default power key high level is the normal state, and the power key low level is the pressed state, and of course, the user may also set the default power key low level to the normal state, and the power key high level to the pressed state. Meanwhile, a user can set the preset time threshold according to the power supply control requirement of the user, and the specific numerical value of the preset time threshold is not specifically limited.

102, monitoring whether the monitoring event occurs or not through the input and output system when the microprocessor is in a working state;

when the microprocessor is in a working state, the level signal of the power supply key can be switched between a high level signal and a low level signal, and the input and output system judges whether a monitoring event occurs or not in the process of monitoring and recording the level use state of the power supply key.

103, when the monitoring event is monitored to occur, determining that the power key is in a short-press state, and calling a shutdown control function through an extensible firmware interface UEFI on the microprocessor to send a first control instruction based on a power state coordination interface protocol PSCI to the microprocessor;

after the power key is determined to be in the short-press state, a shutdown control function is called through UEFI (unified extensible firmware interface), the shutdown control function can be an SMC (sheet molding compound) function, a power management protocol can be a Power State coordination interface Protocol (PSCI), the PSCI is a power management interaction protocol between Linux and ATF (auto-configuration framework) and can be used for power management, and an extensible firmware interface on the microprocessor calls the SMC function so as to send a first control instruction based on the PSCI to the microprocessor through the SMC function.

And 104, converting the first control instruction into a second control instruction based on a system control management protocol SCMI (Single chip computer interface), and executing shutdown operation of the power supply of the server according to the second control instruction by the microprocessor.

The microprocessor converts the first control instruction into a System Control and Management Interface (SCMI) based System Control and Management Interface (SCMI), so that the server power supply executes shutdown operation of the server power supply according to the second control instruction. An application processor (application processor) on the ARM server includes an Operating System (OSPM) and a PSCI power management component (psciccpupperdomain), wherein the OSPM includes a processor power supply (CPUPOWER), a device performance (devicecpupperform), a device power domain (devicepowerdomain), and a sensor (Sensors), the CPUPOWER is connected with the SCMI through the psccpupperdomain, and the deviceupower, the devicepowerdomain, and the Sensors are connected with the SCMI and interact with the system processor through an SCMI protocol.

It should be noted that, the SMC function may transmit a shutdown instruction of the PSCI protocol, that is, PSCI _ SYSTEM _ OFF, to the microprocessor, and the microprocessor executes the PSCI _ SYSTEM _ OFF instruction and controls the server power supply through the SCMI protocol, where the SCMI protocol includes a protocol layer and a transport layer, the protocol layer is used to describe a command that can be supported, and the transport layer defines what way the command is transmitted through to implement a shutdown operation on the server power supply, thereby implementing a setup interface of the input and output SYSTEM and a shutdown function under the Shell.

The embodiment of the invention discloses a power-down control method for a server power supply, which is applied to an ARM server, wherein the ARM server comprises a microprocessor and a power supply key, a monitoring event is set in an input and output system of the ARM server, whether the power supply key is in a pressing state or not is judged through the monitoring event, a power-down control function is called through an extensible firmware interface on the microprocessor after the power supply key is determined to be in a short-pressing state, a first control instruction based on a power supply state coordination interface protocol PSCI is sent to the microprocessor, and the first control instruction is converted into a second control instruction based on a system control management protocol SCMI, so that the server power supply executes power-down operation according to the second control instruction. By adopting the technical scheme, the ARM server can realize the power-off function of short-time pressing of the power key through monitoring the event, the real-time power-off requirement of the ARM server on equipment in the research, development, operation and maintenance processes is facilitated, the time for a user to control the server to be powered off is saved, and the use of the user is facilitated.

At present, the server is very commonly applied in life, and has wide application in education industry, financial industry, telecommunication industry, military administration industry and the like, and the server in the network era plays an increasingly important role. In the process of daily use, the server generally operates autonomously, but when the server fails to operate, the server needs to be managed and maintained. In order to reduce the loss of the server and prolong the service life of the server, the power key functions of most servers are defaulted to realize the startup and shutdown actions of the server through power signals, and the power-on or power-off of alternating current is controlled through a fatigue machine or a power distribution unit by default, so that the cyclic power-on and power-off are realized. In the process of managing and maintaining the server, if the user is in the field, a great deal of time cost and traffic cost are consumed. When the number of servers is large, such as servers in a data center, the number of the servers may be as high as hundreds to thousands, and it takes a lot of time to manually implement the startup and shutdown actions of the servers.

In some embodiments, the real-time and long-distance transmission functions of the Internet provide a good platform for people to transmit control signals to all over the world based on the TCP/IP protocol through the Internet, and if the information of a computer can be transmitted to a remote control end in real time through a device, the remote management server can manage the remote servers as if each server is controlled on site locally. In order to solve the problem that the server power management consumes time, the embodiment of the application remotely controls the controlled terminal through the application and control terminal. The controlled terminal is arranged on the ARM server, the control program is arranged on the controlled terminal and is solidified in an embedded system of the ARM server of the application and control terminal, and when the ARM embedded system is controlled through the application and control terminal, the WEB-based control platform of the ARM embedded system can be accessed through a network without complex operation. Illustratively, the ARM server comprises at least one group of main boards and a bottom board, the main boards and the bottom board are both connected with a power supply of the server, a microprocessor is arranged on the main boards, a bottom board controller is arranged on the bottom board, and the bottom board controller is connected with power supply keys. When a user needs to execute remote power-down control, the control terminal establishes a control link with the controlled terminal through an IP address of a control device connected with the controlled terminal, the control terminal sends control instructions of a mouse and a keyboard to the bottom board controller, and a network card module of the bottom board controller acquires the control instructions and sends the control instructions to the processor for processing. And sending a power supply power-down instruction to a bottom plate controller in the ARM server through the application and control terminal, and starting a power supply key by the bottom plate controller after the bottom plate controller receives the power supply power-down instruction of the server so that the power supply key is in a pressed state. It should be noted that, the embodiment of the present invention has no special requirement on the application and control terminal, and only needs to have a browser and be capable of performing remote connection with the controlled terminal, so that remote control can be performed through any networked computer at any time and any place. According to the embodiment of the invention, the external power supply supplies power to the bottom board controller, so that the bottom board controller can operate independently of the state of the controlled terminal, an ARM embedded system on the bottom board controller can operate no matter whether the power supply of the controlled terminal works, and even if the controlled terminal cannot be automatically restarted due to abnormal power failure, the controlled terminal can be subjected to cold start starting and starting through the remote application and control terminal. The embodiment of the invention is characterized in that a BMC module is arranged on the control device, the control device is connected with the controlled terminal through the IPMB interface, and the operation information of the ARM server mainboard is fed back to the administrator of the control terminal. By adopting the technical scheme, the user can remotely control the power supply of the ARM server at the application and control terminal, and the power supply of the server is manually controlled on site, so that the time of managers is saved, and the control efficiency is improved.

In some embodiments, the ARM server is quite simple to maintain when running and supported by a control system, the management of the server can be realized through remote management software, the management of the server cannot only stay at the level of an operating system, and high-level software of the ARM server can be allowed to communicate with a hardware layer through a certain standard from a bottom layer, so that the management of the server is more complete and transparent. An Intelligent Platform Management Interface (IPMI) is originated from the field of servers, and aims to provide functions of equipment management, sensor event management, user management, remote maintenance and the like for the servers. The IPMI has the characteristics of standardization, separation of a management channel and a service channel, rich command set, high safety and the like. The IPMI has high applicability due to the characteristic that the management channel and the service channel of the IPMI are separated, the power supply of an IPMI subsystem is independent, the IPMI is independent from the service management system and still has operability even when the service system fails, the IPMI is an intelligent management platform interface based on the Internet, the core of the IPMI is a server processor or a Baseboard Management Controller (BMC) which does not depend on the processor, the BIOS or an operating system of the server to work, the baseboard management controller can independently run in the system without an agent management subsystem, the IPMI can start to work as long as BMC and IPMI firmware are available, and a BMC chip can be arranged on a mainboard of an ARM server to provide IPMI support for the server mainboard through the BMC. The good autonomy of IPMI overcomes the limitation of the management mode based on the operating system in the past, for example, the operating system can still perform the operations of startup and shutdown, information extraction and the like under the condition that the operating system does not respond or is not loaded.

In some embodiments, the server power input is typically 220V AC, and the 220V AC is coupled to the server power input via a power cord. The 220V alternating current is converted into two direct currents of P12V _ main and P12V _ STBY in the server power supply. The two kinds of power are 12V voltage, and the difference is that the current provided by P12V _ main is larger, and in addition, the P12V _ main needs to receive a power supply enabling signal to be converted into the output voltage of the system mian power for other chips or components. And the current provided by the P12V _ STBY is smaller, the P12V _ STBY automatically outputs voltage after being inserted into an AC line, and the control of a power supply enable signal is not carried out.
