Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

According to the related art, when a server performs some specific functions, the function keys corresponding to the processor are connected to a baseboard management controller, and when the server detects the triggering of the function keys, the baseboard management controller processes the triggering signals of the function keys and then sends the signals to a Complex Programmable Logic Device (CPLD). Therefore, the prior art relies on the baseboard management controller to realize the functions, and when the baseboard management controller fails, the functions cannot be completed normally, so that a certain limitation is caused to the use of the server.
For example, when the startup function or the shutdown function is executed, the startup function and the shutdown function need to be executed under the BMC Active condition, and if the baseboard management controller cannot be started normally, the server cannot be started or shut down normally.
As another example, in some special situations, where the server cannot use the baseboard management controller (not because of the failure of the baseboard management controller), the prior art cannot cover such scenarios.
As an example, for some processor architectures servers that are not capable of executing a Power Button (pwr_btn) signal, a Reset Button (reset_btn, rst_btn) signal, and a Power control signal (Sleep s5#, slp_s5#), a baseboard management controller is typically employed to implement the relevant functions. For example, referring to fig. 2, fig. 2 is a timing topology diagram of power control of a server without a switch related signal architecture processor. The method specifically comprises the following steps:
the baseboard management controller is connected with the central processing unit through an eSPI bus, and the bus is used for command interaction between the baseboard management controller and the central processing unit.
The baseboard management controller is provided with an input of a switch-on button (PWR_BTN) for a switch operation, and an input of a reset button (RST_BTN) for a reset operation.
The baseboard management controller is connected with the complex programmable logic device through a system_pwr_on signal, and the signal is used for informing the complex programmable logic device to start or stop power supply; when the baseboard management controller receives a command and needs to start, the signal is set high, and the voltage regulation module is controlled by the complex programmable logic device to start power supply; when the baseboard management controller receives the shutdown signal, the signal needs to be set low, and the voltage regulation module is controlled by the complex programmable logic device to stop supplying power.
The complex programmable logic device is connected with the central processing unit through a system_pwr_ok signal, and the signal is used for informing the central processing unit that all power supplies on the main board of the central processing unit reach the working standard and can perform initialization work.
A cpu_reset signal is provided between the complex programmable logic device and the central processing unit, and is used for resetting the central processing unit.
A Power Enable signal (abbreviated as EN) is arranged between the complex programmable logic device and the voltage regulation module and is used for enabling or stopping the output of the voltage regulation module; there are multiple voltage regulation modules within a server system, each with an independent EN signal.
A Power Good signal (PGD for short) is arranged between the complex programmable logic device and the voltage regulation module, and is used for obtaining the output state of the voltage regulation module; there are multiple voltage regulation modules within a system, each with an independent PGD signal.
Referring to fig. 1 or fig. 3, fig. 1 is a schematic diagram illustrating a control method of a server according to an embodiment of the present invention. The server comprises a baseboard management controller and a complex programmable logic device; the output signal of the first interface of the baseboard management controller and the trigger signal of the function key of the first function to be executed are input into the first interface of the complex programmable logic device after first logic AND processing.
The control method comprises a step S1 and a step S2; wherein,
step S1, when the triggering of the processing result of the first logic AND processing is detected, simulating the control pulse corresponding to the first function to be executed.
And step S2, the control pulse is sent to a first interface of the complex programmable logic device so as to execute the first function to be executed.
Further, referring to fig. 4, fig. 4 is a schematic diagram of a timing control topology of a server according to an embodiment of the present disclosure.
Wherein,
the baseboard management controller is connected with the central processing unit through an eSPI bus, and the bus is used for command interaction between the baseboard management controller and the central processing unit.
The baseboard management controller performs first logic and processing through BMC-GPIO2 and PWR_BTN and then sends the processed result to CPLD-GPIO5 to input a system on-off signal. When the PWR_BTN key is pressed or the baseboard management controller receives a startup and shutdown command, a key action is simulated through the BMC-GPIO1 to generate a low pulse (namely, a control pulse corresponding to the first function to be executed is simulated), and the system is triggered to execute startup or shutdown time sequence.
On the other hand, the embodiment may further have a second function to be executed. The output signal of the second interface of the baseboard management controller and the trigger signal of the function key of the second function to be executed are input into the second interface of the complex programmable logic device after the second logic AND processing is carried out; whereby the control method further comprises: simulating a control pulse corresponding to the second function to be executed when the trigger of the second logic and the processing result is detected; and sending the control pulse to a second interface of the complex programmable logic device to execute the second function to be executed.
For example, the baseboard management controller performs second logic and post-processing through BMC-GPIO1 and RST_BTN, and sends the second logic and post-processing to CPLD-GPIO6 for inputting a system RST signal. When RST_BTN is pressed or RST command is received by the baseboard management controller, a key action is simulated through BMC-GPIO1 to generate a low pulse (namely, a control pulse corresponding to the second function to be executed is simulated), and system reset is triggered. It should be noted that, in the foregoing preferred embodiment, in the actual application process, the first function to be executed may be a power-on function, a power-off function or a reset function, and the second function to be executed may be a power-on function, a power-off function or a reset function, which may be specifically set according to the actual application scenario requirement of the server. The startup function, the shutdown function and the reset function can be triggered by corresponding function keys without a baseboard management controller, so that the limitation of the baseboard management controller on the server can be relieved.
In addition, the complex programmable logic device is connected with the central processing unit through a system_pwr_ok signal, and the signal is used for informing the central processing unit that all power supplies on the main board of the central processing unit reach the working standard, so that the initialization work can be performed.
A cpu_reset signal is provided between the complex programmable logic device and the central processing unit, and is used for resetting the central processing unit.
A Power Enable signal (abbreviated as EN) is arranged between the complex programmable logic device and the voltage regulation module and is used for enabling or stopping the output of the voltage regulation module; and there are multiple voltage regulation modules in a server system, each voltage regulation module having an independent EN signal.
A Power Good signal (abbreviated PGD) is arranged between the complex programmable logic device and the voltage regulation modules, and is used for obtaining the output state of the voltage regulation modules, and each voltage regulation module has an independent PGD signal.
A poweroff_req signal (Power off Request, shutdown request signal) is provided between the complex programmable logic device and the central processing unit. In the starting-up state, when the complex programmable logic device detects that the PWR_BTN key is pressed or a Power Off signal sent by the baseboard management controller is detected, the CPU is notified through the Power off_req signal, and shutdown is requested; after receiving the signal, the CPU informs the operation system to stop the operation of the related application until the CPU is allowed to be powered off. The signal defaults to high level after power-on, and a low level pulse is sent to the central processing unit when a power-off request occurs.
After the central processing unit receives an instruction that the operating system can be powered Off, the central processing unit informs the complex programmable logic device through a Poweroff_Act signal (Poweroff_Act, executing a shutdown signal), and the Poweroff_Act signal is pulled down until the central processing unit is powered Off; the complex programmable logic device detects that this signal changes from high to low, and then performs the associated shutdown sequence, such as pulling down the level of the cpu_reset signal, the system_pwr_ok signal, and so on.
For the implementation of the embodiment of the present application, for the step S1, the detection of the triggering of the processing result of the first logical and processing means that the pwr_btn is pressed or the baseboard management controller receives an instruction, and at this time, a pwr_btn button action (corresponding control pulse) is simulated through the BMC-GPIO 2. Thus, the operation corresponding to the power-on function or the power-off function in step S2 can be further performed.
As an example of the present embodiment, the first function to be executed may be a power-on function or a power-off function. The server further includes a central processing unit, when the first function to be executed is a power-on function of the server, please refer to fig. 5, the sending the control pulse to the first interface of the complex programmable logic device to execute the first function to be executed includes:
Transmitting the control pulse to a first interface CPLD-GPIO5 of the complex programmable logic device; then judging the current running state of the server, and starting to execute a starting action when the running state is a shutdown state, namely starting the voltage regulation modules in sequence according to a first preset time sequence; and when the preset voltage regulation condition is met, the central processing unit is controlled to initialize so as to realize the starting-up function.
Further, when the preset voltage regulation condition is met, the central processing unit is controlled to initialize, including: when the last opened voltage regulation module reaches a preset output standard, a System ready instruction (system_pwr_ok signal) is sent to the central processing unit through the complex programmable logic device, and an initialization instruction is sent to the central processing unit after a preset time period, namely, the CPU_reset signal is released, so that the central processing unit responds to the initialization instruction to execute initialization operation, and the starting-up flow is ended at the moment. The implementation of the application takes the voltage regulating module as the preset voltage regulating condition for judging the initialization time of the central processing unit, and can ensure that all the voltage regulating modules reach the ready state when the server is started, so as to ensure the normal and stable operation of each module after the server is started.
When the first function to be executed is a shutdown function of the server, referring to fig. 6, the sending the control pulse to the first interface of the complex programmable logic device to execute the first function to be executed includes:
transmitting the control pulse to a first interface CPLD-GPIO5 of the complex programmable logic device; judging the current running state of the server, and when the running state is a starting state, sending a shutdown request signal to the central processing unit through the complex programmable logic device so that the central processing unit responds to the shutdown request signal to control an operating system of the server to execute shutdown actions; when the central processing unit accords with a preset change condition, sending an execution shutdown signal Poweroff_Act to the complex programmable logic device through the central processing unit so that the complex programmable logic device responds to the execution shutdown signal to execute power-down operation, wherein the complex programmable logic device detects that the execution shutdown signal Poweroff_Act is set low, and the levels of a CPU_reset signal and a system_pwr_ok signal are pulled down; and sequentially closing the voltage regulation module according to a preset time sequence, and pulling down the level of the CPU_reset signal and the level of the system_pwr_ok signal so as to realize the shutdown function of the server.
Preferably, the shutdown action is performed in an operating system controlling the server, which sets the relevant registers of the central processing unit. And when the central processing unit meets the preset change condition, sending an execution shutdown signal to the complex programmable logic device through the central processing unit, wherein the execution shutdown signal comprises the following steps: and when detecting that the state of the register of the central processing unit changes, sending an execution shutdown signal to the complex programmable logic device through the central processing unit.
By implementing the embodiment of the application, as the output signal of the first interface of the baseboard management controller and the trigger signal of the function key of the first function to be executed are subjected to the first logic AND processing and then input into the first interface of the complex programmable logic device, the first interface can be realized through the triggering of the corresponding function key without depending on the baseboard management controller, and the first interface is not powered on or powered off. For example, before the server is started, the baseboard control manager needs to be started first, the starting time of the baseboard control manager needs 2 minutes, the starting time of the baseboard control manager needs tens of milliseconds, and if the baseboard control manager is triggered through the function keys, the baseboard control manager does not need to be started, so that the waiting time of a user is shortened. Similarly, when the power-off is needed, the running state of the substrate control manager can be determined without spending time, starting of the substrate control manager is not needed to be waited, and the like, so that the user experience can be effectively improved; in addition, considering that the complex programmable logic device itself is more stable than the baseboard control manager, the reliability of the server system can be improved while reducing the dependency on the baseboard control manager.
It should be noted that, when the shutdown function is aimed at, in addition to the detection of the triggering of the processing result of the first logic and the processing in step S1, a shutdown command may be directly issued in the operating system, if the shutdown command is issued in the operating system, after the operating system completes the shutdown process, the operating system also sets a register of the central processing unit, and then the state of the register of the central processing unit may be detected to change, and a second shutdown command is sent to the complex programmable logic device through the central processing unit, so as to implement shutdown of the server.
For example, the set register of the central processing unit may be a cpu_status_reg, with a default value of 4' b 0000, where the specific meanings of the different values respectively include: 0000: sleep_s5, 0001: sleep_s3, 0010: sleep_s0. Upon detecting that the cpu_status_reg is changed from 0010 to 0000, a power-down operation is performed. The state change of the related register of the central processing unit is detected as a preset change condition, and whether the operating system completely executes the shutdown process can be determined, so that the shutdown process of the server is prevented from being damaged because the operating system does not execute the complete shutdown process.
Correspondingly, referring to fig. 7, the embodiment of the invention also provides a control device of a server, wherein the server comprises a baseboard management controller and a complex programmable logic device; the output signal of the first interface of the baseboard management controller and the trigger signal of the function key of the first function to be executed are input into the first interface of the complex programmable logic device after first logic AND processing is carried out;

the control module 102 is configured to send the control pulse to a first interface of the complex programmable logic device to execute the first function to be executed.
