Description
Technical Field
The invention relates to the technical field of computers, in particular to a low-temperature power-on self-starting method, a system, a device and a medium of an edge server.
Background
At present, a method for powering on and automatically starting up a server commonly adopted by an Intel X86 platform is as follows: the State of the option "State After G3" is modified under BIOS SETUP. And G3 represents that the power supply state of the server is a state that the power supply is cut off and the server is completely powered off. There are three options for this option, S0: after the representative server is electrified, the representative server is started by itself, and the CPU runs to the S0 state to load the BIOS code and is guided to enter the system; the second state is S5: after the representative server is powered on, keeping the state of the CPU as S5, namely a shutdown state; the third option is, last state: after the representative server is powered on, the server is kept in a state before the server is powered off, that is, before the server enters the G3 state, for example, if the server before the server is powered on is in a power-on state, the server is automatically powered on to enter the S0 state when the server is powered on again, and if the server is in a power-off state before the server is powered off, the server is powered off to maintain the S5 state when the server is powered on again.
However, the current solutions have the following drawbacks:
1. the implementation of this scheme relies on a RTC powered register to record the value of the option "State After G3" and to record the on and off State of the machine before power up. After the server is powered on, the PCH is powered on, and the ME in the PCH can determine whether to send a starting signal to the CPU by judging the state of the register, so that whether to start the server when the server is powered on next time is controlled. If the battery voltage is too low, the state of the register cannot be maintained, and the server cannot be powered on or powered off as required according to the requirements of customers.
2. If the server is in a low-temperature environment, for example, in an edge server scene, the low temperature of the machine may reach minus 40 ℃, generally, in order to solve the problem of the low-temperature environment, the current MCU may detect the ambient temperature after receiving a power-on key signal and before sending an instruction to the CPU to notify the power-on, if the temperature is too low, the heating sheet is enabled to heat the server, and after the temperature reaches the standard, a signal is sent to enable the CPU to power on. At this time, if the power-on automatic start is set, power is supplied to the PCH, and after the ME code is loaded internally, the CPU is controlled to start up and enters the S0 state, and other devices of the server cannot normally start up due to low temperature, so that the server is down or has abnormal functions.

Detailed Description
The core of the invention is to provide a low-temperature power-on self-starting method of an edge server, in the prior art, because the register state can not be maintained due to the too low RTC voltage, the ME in the PCH can not send out a correct control signal, and the normal power-on self-starting function can not be realized. In addition, if the server is in a low-temperature environment, other devices of the server cannot be normally started due to low temperature, and a downtime or abnormal function occurs.
The low-temperature power-on self-starting method of the edge server provided by the invention realizes three requirements of automatic power-on starting, power-on shutdown and power-on power-off state maintenance through the communication of the BIOS, the BMC and the MCU and the storage of the state mark by the EEPROM. The invention uses EEPROM to store the status flag, and MCU monitors the status flag to execute the control logic, thus avoiding the failure of maintaining the register status due to too low RTC voltage, failure of ME in PCH to send out correct control signal and failure of normal function realization. Meanwhile, in a low-temperature scene, the action of controlling the heating of the heating sheet and the action of controlling the server State after G3 are controlled and executed by the MCU, so that the condition that the server is electrified and automatically started under the condition that the temperature of peripheral IO equipment and the like does not reach the standard is avoided.
In order that those skilled in the art will better understand the disclosure, reference will now be made in detail to the embodiments of the disclosure as illustrated in the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1, the embodiment provides a low-temperature power-on self-starting method for an edge server, including the following steps:
s1: after the power is on, the temperature of the server is monitored through the MCU, and the temperature of the server is ensured to meet the starting condition.
Specifically, after the power is on, the MCU executes a temperature control program by loading a code, acquires a temperature value by a built-in temperature sensor of the server, and compares the temperature value with a preset value. If the temperature value is greater than or equal to the preset value, the starting condition is met, and the next step is directly executed; if the temperature value is smaller than the preset value, the starting condition is not met, the heating action of the heating sheet is continuously executed, and the temperature is continuously monitored until the starting condition is met.
S2: acquiring a flag MCUFlag0 and a flag MCUFlag1 through the MCU, and judging whether to send a starting signal to the CPU according to the flag; if yes, executing step S3; otherwise, the current state is maintained until power is turned off.
Specifically, the MCU obtains the flag bits MCUFlag0 and MCUFlag1 from the built-in EEPROM, and performs an and calculation on the MCUFlag0 and MCUFlag1 to generate a calculation result. At the moment, whether a starting signal is sent to the CPU is judged according to the calculation result, if the calculation result is 1, the starting signal is sent to the CPU, and the subsequent CPU enters an S0 state; if the calculation result is 0, the state is maintained, and the CPU is in an S5 state and is maintained to be powered down.
S3: and sending a starting signal to the CPU through the MCU to enable the CPU to enter an S0 state.
S4: and loading and initializing IPMI through BIOS, and setting MCUFlag1 to be 1.
Firstly, the CPU memory and the IO equipment are initialized through the BIOS, and a boot system is loaded and started. Then, initializing the IPMI service of the BIOS through the BIOS for interacting with the BMC, and after the IPMI initialization is completed, setting the current MCUFlag1 to be 1 by the BIOS to indicate that the current server is in a starting state.
S5: and the BIOS sends the MCUFlag1 to the MCU through the BMC and stores the MCUFlag 1.
The method specifically comprises the following steps: the BIOS sends the MCUFlag1 to the BMC through an IPMI command; after receiving the MCUFlag1, the BMC establishes communication with the MCU through the I2C, sends the MCUFlag1 to the MCU, and stores the MCUFlag1 in an EEPROM built in the MCU for next judgment and use.
S6: and the BIOS acquires the value of the current SetUp option State After G3, sets MCUFlag0 according to the acquired value, and stores the value.
Firstly, the BIOS acquires the value of the current SetUp option State After G3; if the obtained value is S0 or Last Status, setting MCUFlag0 to 1; if the acquired value is S5, MCUFlag0 is set to 0; after the MCUFlag0 is set, the BIOS sends the MCUFlag0 to the MCU through the BMC and stores the MCUFlag0 in the EEPROM built in the MCU.
The following are specifically mentioned:
if the power is abnormally powered off, when the power is powered on again, the Last State of the server is S0, namely the power-on State.
If the set "State After G3" is "S0" or "Last Status", the MCU should send a power-on signal to make the CPU enter S0, and actually the values of MCUFlag0 and 1 are both 1, and the flag bit and the calculation result are 1, referring to step S2, the CPU will execute the power-on action and enter S0 State, which is in accordance with expectations.
If the set "State After G3" is "S5", the MCU should not send a power-on signal to keep the CPU in the S5 State, actually, the MCUFlag0 value is 0, the MCUFlag1 value is 1, the flag bit is 0 After the and calculation, referring to step S2, the power-on action is not performed, and the CPU will keep the S5 State, which is expected.
S7: judging whether a shutdown action occurs at present; if yes, step S8 is executed, otherwise, the current state is maintained until power is off.
S8: executing an S5CallBack function through the BIOS, and judging whether the value of the State After G3 is the Last Status; if yes, step S9 is executed, otherwise, the current state is maintained until power is off.
S9: setting MCUFlag1 to 0 through BIOS, and storing.
Firstly, setting MCUFlag1 to be 0 in an S5CallBack function through a BIOS; then, the BIOS sends the MCUFlag1 to the MCU through the BMC and stores the MCUFlag in an EEPROM built in the MCU.
It should be noted that if a normal shutdown operation occurs in the power-on state, the S5CallBack function of the BIOS is triggered. At this time, the server is going to enter the S5 State, and if "State After G3" is selected as "Last Status", the server should be in the power-off State After being powered on again (S5). The Intel X86 architecture CPU is realized by writing a fixed numerical value into a fixed IO address to trigger an interrupt, and the BIOS associates the interrupt with a self-defined S5CallBack function in the form of registering an interrupt processing function. Registering an interrupt handling function is a routine action of the BIOS. In the S5CallBack function, the value of the current SetUp option "State After G3" is obtained, and if the value is "S0" or "Last Status", MCUFlag1 is set to 0. If the value is S5, BIOS does not act, i.e., MCUFlag1 remains at 1.
At this time, the CPU enters the S5 State after shutdown, and if the power is abnormally turned off, the Last State of the server is S5 when the power is turned on again, namely the power-off State.
If the set "State After G3" is "S0", the MCU should send a power-on signal to make the CPU enter S0, and actually the values of MCUFlag0 and 1 are both 1, and the flag bit and the calculation result are 1, referring to step S2, the power-on action is executed, and the CPU enters S0, which is in line with expectations.
If the set "State After G3" is "S5", the MCU should not send a power-on signal to keep the CPU on S5, and actually the MCUFlag0 value is 0, the MCUFlag1 value is 0, the flag bit is summed with the calculated flag bit result is 0, and referring to step S2, the power-on operation is not executed, and the CPU maintains the S5 State, which is expected.
If the set "State After G3" is "Last Status", the MCU should not send a power-on signal to keep the CPU in S5, and actually the value of MCUFlag0 is 1, the value of MCUFlag1 is 0, the flag bit is 0 After the and calculation, the power-on action is not executed in reference to step S2, and the CPU maintains the State of S5, which is in accordance with expectations.
S10: and powering off the server.
Therefore, the method essentially provides a starting process that the edge server is powered on after abnormal power-off and is powered off again. Under a low-temperature scene, after the abnormal power failure is re-electrified, the edge server realizes the execution flow of the function of 'State After G3'. The MCU has two states to be judged, MCUFlag0: state After G3, MCUFlag1: last State. The values of the two flags are determined by the BIOS and are sent to the BMC through the IPMI, and the BMC and the MCU are communicated through an I2C link and are stored in the EEPROM by the MCU.
The embodiment provides a low-temperature power-on self-starting method of an edge server, which realizes three requirements of automatic power-on starting, power-on shutdown and power-on power-off before maintenance by communicating a BIOS (basic input/output system) with a BMC (baseboard management controller) and an MCU (micro control unit) and storing a state mark by an EEPROM (electrically erasable programmable read-only memory). The method uses the EEPROM to store the state mark, and the MCU monitors the state mark and executes the control logic, thereby avoiding that the register state can not be maintained due to too low RTC voltage, the ME in the PCH can not send out correct control signals, and the function can not be normally realized. Meanwhile, in a low-temperature scene, the action of controlling the heating of the heating sheet and the action of controlling the server State after G3 are controlled and executed by the MCU, so that the condition that the server is electrified and automatically started under the condition that the temperature of peripheral IO equipment and the like does not reach the standard is avoided.

And the starting unit 3 is used for sending a starting signal to the CPU through the MCU so as to enable the CPU to enter an S0 state.
And the flag bit setting unit 4 is used for setting the values of the flag bits MCUFlag0 and MCUFlag1 through the BIOS.

And the flag bit storage unit 5 is used for controlling the BIOS to send the MCUFlag0 and the MCUFlag1 to the MCU through the BMC and store the MCUFlag0 and the MCUFlag 1. The flag bit storage unit 5 is specifically configured to: the BIOS sends the MCUFlag0 and the MCUFlag1 to the BMC through an IPMI command; after receiving the MCUFlag0 and the MCUFlag1, the BMC establishes communication with the MCU through the I2C, sends the MCUFlag0 and the MCUFlag1 to the MCU, and stores the MCUFlag0 and the MCUFlag1 in an EEPROM built in the MCU.
