Description
Technical Field
The invention relates to the field of system program control and data access, in particular to a method for recording system logs during system startup.
Background
The system log records the information of all the states and problems in the hardware, software and system, and also monitors the events occurred in the system. The user can check the cause of the error occurrence through it, or find the trace left by the attacker when the System is under attack, in the System startup process, when the Basic Input/Output System (BMC) needs to start Power-On Self-Test (POST) by the Basic Input/Output System (BIOS), a System Event Log (SEL) is recorded, but when the System is started, the BIOS will perform the related setting of the fast channel Interconnect (QPI) soon (within about four seconds and five seconds) after the POST is started, so that the reset of the Low Pin Count Interface (LPC) is generated, so the Basic Input/Output System needs to be powered On again for Self-Test to make the above setting effective, so far, since the substrate Management Controller performs the Self-Test twice during the System, therefore, the system will record the system log (Start Of POST event log) Of the Start Of two power-on self-tests, which is easy to cause trouble when the user checks the log record afterwards.
For the above reasons, it is necessary to overcome the above disadvantages and provide a method for recording system logs during system startup, so that only one system log at which power-on self-test starts is recorded during system startup, which is convenient for a user to check after the system log is started, and is not easy to cause troubles.
Disclosure of Invention
Therefore, in view of the above situation, an object of the present invention is to provide a method for recording system logs during system startup, so that a baseboard management controller only records a system log at the beginning of a power-on self-test during system startup, which is convenient for a user to view.
In order to achieve the above object, the present invention provides a method for recording a system log when a system is powered on, the method comprising:
after a starting button of the system is pressed and the power-on is completed, setting initial values of a recording flag and an ignoring flag respectively;
when a base plate management controller Of the system monitors that the voltage state Of the Start Of POST GPIO is changed from high level to low level, recording a system log at the beginning Of the first power-on self-test according to the initial values Of the recording flag and the neglecting flag, and resetting the modified values Of the recording flag and the neglecting flag;
the basic input/output system carries out a second power-on self-test, the voltage state Of a general purpose output/input interface (Start Of POST GPIO) representing the Start Of the power-on self-test is set to be low level from high level, when a baseboard management controller Of the system monitors that the voltage state Of the Start Of POST GPIO is changed from high level to low level, the baseboard management controller does not record the system log Of the Start Of the second power-on self-test according to the modified values Of the recording flag and the neglecting flag.
Specifically, the initial values of the record flag and the ignore flag are 1 and 0, respectively, when the bmc determines that the value of the record flag is 1, a system log at which the power-on self-test starts is recorded, and when the bmc determines that the value of the ignore flag is 0, the system log is not ignored.
Specifically, the modified values of the record flag and the ignore flag are 0 and 1, respectively, when the bmc determines that the value of the record flag is 0, a system log of the start of power-on self-test is not recorded, and when the bmc determines that the value of the ignore flag is 1, the system log is ignored.
In particular, after the basic input and output system of the system performs the first power-on self-test, the system performs the setting of the fast channel interconnection, and generates the reset of the low pin count interface, and the basic input and output system performs the second power-on self-test.
Specifically, after the system is powered on, the baseboard management controller receives the PSGood signal generated by the system.
Compared with the prior art, the method for recording the system log when the system is started in the invention only records a system event log at the start of the power-on self-test in the starting process of the system by changing the high/low level state of a General Purpose Input/Output (GPIO) representing the power-on self-test state and matching with the setting of the ignore flag and the recording flag, thereby being convenient for a user to check the system event log after the system is started and not easy to cause trouble.
[ description of the drawings ]
FIG. 1 is a flowchart of a method for logging system logs when the system is powered on.
[ detailed description ] embodiments
The method for recording the system log when the system is started ensures that only one system event log at the beginning of the power-on self-test is recorded in the starting process of the system by changing the high/low level state of the general output/input interface of the power-on self-test and matching with the setting of the ignore flag and the recording flag, thereby being convenient for a user to check the system event log after the system is started and not easy to cause troubles.
Referring to fig. 1, a flow chart of a method for recording system logs when the system of the present invention is powered on is shown,
step 11: judging whether a starting button of the system is pressed (the substrate management controller receives a PSgood signal sent by the system), if so, turning to the step 12, otherwise, ending the process;
step 12: setting the initial value of the record flag as 1, ignoring the initial value of the flag as 0, and proceeding to step 13;
step 13: the basic input and output system of the system is electrified and self-checked, and then the step 14 is carried out;
step 14: the BIOS sets the voltage state Of a general purpose output/input interface (Start Of POST GPIO) representing the Start Of the power-on self-test from a high level to a low level, the substrate management controller monitors the general purpose output/input interface and goes to the step 15;
step 15: judging whether the value of the ignore flag is constantly equal to 1, if yes, going to step 16, if no, going to step 17;
step 16: setting the ignore flag to recover its initial value to 0 and ending the process;
and step 17: judging whether the value of the recording flag is constantly equal to 1, if yes, going to step 18, if no, going to step 19;
step 18: setting the modified value of the record flag to 0, ignoring the modified value of the flag to 1, and proceeding to step 19;
step 19: recording a system log of the start of the power-on self-test, and turning to the step 20;
step 20: setting a fast channel interconnection for a basic input and output system of the system, and turning to step 21;
step 21: the BIOS of the system resets the low pin count interface, and goes to step 13, the BIOS of the system performs a second power-on self-test, and further continues to determine whether the value of the ignore flag is equal to 1, and goes to step 16 to set the ignore flag to return to its initial value of 0 and end the process because the ignore flag is a modified value of 0.
In this embodiment, the present invention is a method of firmware executed by a Baseboard Management Controller (BMC), and in the above steps, except that the steps 14, 20, and 21 are executed by a basic input/output system of a system, the other steps are executed by the BMC.
In this embodiment, when the bmc determines that the value of the record flag is 1, a system log at the start of the power-on self-test is recorded, and when the bmc determines that the value of the ignore flag is 0, the system log is not ignored.
In this embodiment, when the bmc determines that the value of the record flag is 0, a system log at the start of power-on self-test is not recorded, and when the bmc determines that the value of the ignore flag is 1, the system log is ignored.
In this embodiment, after the bios of the system performs the first power-on self-test, the bios performs the fast channel interconnect setting, and generates the reset of the low pin count interface, and then performs the second power-on self-test.
In this embodiment, after the system is powered on, the bmc receives the PSGood signal generated by the system, that is, when the system is powered on when the system power-on button is pressed, the system generates a PSGood signal (power supplied power good signal), that is, the BIOS can start the POST process only after the system is powered on, and thus the bmc must receive the PSGood signal (indicating that the system is powered on).
It can be seen from the above flowchart that, since the initial values of the record flag and the ignore flag are set, and the modified values of the record flag and the ignore flag are reset after the system log at the beginning of the power-on self-test is recorded for the first time, the step of recording the system log at the beginning of the power-on self-test is not executed any more after the basic input/output system of the system performs the second power-on self-test, and therefore, only the system log at the first power-on self-test is recorded in the whole startup process of the system, which is convenient for the user to check and is not easy to cause trouble.
The embodiments and examples of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments and examples, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
