Description

Dynamic setting method, system, terminal and storage medium for voltage regulator set value
Technical Field
The invention relates to the technical field of servers, in particular to a method, a system, a terminal and a storage medium for dynamically setting a set value of a voltage regulator.
Background
In the existing server, there are some VR (voltage regulator) devices on each motherboard to automatically maintain a constant voltage and ensure the range and stability of voltage operation. The voltage regulator compares the measured value of the production process parameter with a set value, and after obtaining deviation, the voltage regulator generates an output signal according to a certain regulation rule to push the actuator to eliminate the deviation value, so that the parameter is kept near the set value or is changed according to a preset rule. However, during the development and system operation, it may be necessary to change the setting value, such as OCP, etc., and the protection setting value of the voltage regulator VR is fixed after the VR firmware is burned, and the VR firmware is usually burned again or the setting value is dynamically reset through the BMC.
The method for burning the VR Firmware again includes remotely logging in a machine to be refreshed through an IP address of a BMC management network port, and executing a compiled driving program under a system to achieve remote refreshing and upgrading of a CPU or a memory VR Firmware on a fault server mainboard in a machine room. Because the VR can be erased only a few times, usually about 30 times, the method has the disadvantage that if the VR is changed for a plurality of times, the VR cannot be burned, and the function is invalid.
The BMC dynamically resets the setting value, but when the BMC is restarted (for about at least 30 seconds) or the power supply is powered up again, the BMC cannot operate due to the reloading of the program, and cannot provide a prompt change.

IPMI is known as Intelligent Platform Management Interface. IPMI is a specific specification definition of the concept of "platform management", which defines the software and hardware architecture, interaction instructions, event formats, data records, capability sets, etc. of "platform management".
The CPLD adopts programming technologies such as CMOS EPROM, EEPROM, flash memory, SRAM and the like, thereby forming a programmable logic device with high density, high speed and low power consumption. The CPLD is mainly composed of a logic block, a programmable interconnection channel and an I/O block.
The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus to transfer data and to generate a clock to open up the devices that are transferring, when any addressed device is considered a slave device. If the host wants to send data to the slave device, the host addresses the slave device first, then actively sends the data to the slave device, and finally the host terminates the data transmission; the master device addresses the slave device first if the master device is to receive data from the slave device. The host is responsible for generating the timing clock and terminating the data transfer.
OCP overcurrent Protection (Over Current Protection) is a Protection method for operating a Protection device when a Current exceeds a predetermined maximum value. When the current flowing through the protected original exceeds a preset value, the protection device is started, and the selectivity of action is ensured by time limit, so that the circuit breaker trips or gives an alarm signal.

and receiving voltage regulator setting parameters written into the BMC by a user through an IPMI (intelligent platform management interface) interface command through an integrated circuit bus, wherein the setting parameters comprise an integrated circuit bus address of the voltage regulator, an integrated circuit bus channel, a register command position, a command length and a setting value.
3. The method of claim 2, wherein sending voltage regulator setting parameters to the voltage regulator after monitoring the server restart, and updating the voltage regulator setting values with the setting parameters comprises:
powering on again after the server operating system is powered off, and sending a set value to a target voltage regulator according to an integrated circuit bus address and an integrated circuit bus channel of the voltage regulator in the set parameters;
and calling a setting command of the voltage regulator according to the command position and the command length of the register, and executing the setting command to set the set value as the actual set value of the voltage regulator.
4. The method of claim 1, further comprising:
and monitoring the on-site state of the CPLD in real time by mutually losing the dog feeding signal with the BMC.
5. A system for dynamically setting a voltage regulator setpoint, comprising:
the parameter receiving unit is used for receiving the voltage regulator setting parameters sent by the BMC by the CPLD and storing the voltage regulator setting parameters to the local CPLD;

the parameter receiving module is used for receiving voltage regulator setting parameters written into the BMC by a user through an IPMI interface command through an integrated circuit bus, and the setting parameters comprise an integrated circuit bus address of the voltage regulator, an integrated circuit bus channel, a register command position, a command length and a setting value.
7. The system according to claim 6, wherein the parameter setting unit comprises:
the data sending module is used for powering up the server operating system again after powering down, and sending a set value to the target voltage regulator according to the integrated circuit bus address and the integrated circuit bus channel of the voltage regulator in the set parameters;
and the data updating module is used for calling a setting command of the voltage regulator according to the register command position and the command length, executing the setting command and setting the setting value as the actual setting value of the voltage regulator.
8. The system of claim 5, further comprising:
and monitoring the on-site state of the CPLD in real time by mutually losing the dog feeding signal with the BMC.
9. A terminal, comprising:
a processor;
a memory for storing instructions for execution by the processor;
wherein the processor is configured to perform the method of any one of claims 1-4.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the method according to any one of claims 1-4.
