Description
Technical field
The present invention relates to a kind of monitoring system and method for smi signal overtime, espespecially a kind of BMC computational loads that reduce
The monitoring system and method for smi signal overtime.
Background technology
The current state of BMC meetings monitoring system, and the event of generation is write down, wherein, SMI Timeout sensor, it is
BMC monitoring BIOS SMI (System Management Interface) utilizes either with or without an abnormal sensor occurs
From the point of view of GPIO signal, normal transmission signal can high-low voltage interaction bounce, if signal maintains low-voltage always, and when
Between continue too long, then to represent SMI work and stop, occurring abnormal, BMC will record this event.Judge signal either with or without always
The mode of low-voltage is maintained, is generally only done using the interruption for receiving hardware, is skipped to when receiving high voltage in low-voltage
During disconnected A, BMC writes down the time started, and when receiving low-voltage and skipping to high voltage and interrupt B, BMC writes down the end time, and calculates A.B points
Time difference, if having occur timeout phenomenon, but SMI signals bounce it is very frequent, it is per second in have more than once, if
In this way, as long as having an interruption every time, BMC, which just needs to interrupt current work, to be gone to note down and calculate the time, causes BMC's
Load can be very heavy.
The content of the invention
It is a primary object of the present invention to provide a kind of monitoring system for the smi signal overtime for reducing BMC computational loads
And method.
The present invention provides a kind of monitoring system of smi signal overtime, monitors BIOS's by way of poll by BMC
The smi signal that GPIO pin pin are transmitted, it includes:
For setting the setup module of polling cycle and default overtime standard, and the end points of polling cycle is poll point；
Monitor the detecting voltage module of the voltage levels of smi signal at poll point;
The flag detecting module of GPIO status information in polling cycle is monitored, the status information includes and is relevant to the SMI
One state flags value of signal whether be one indicate in the polling cycle exist an at least voltage decline the first flag
It is worth or indicates the acquiescence flag value declined in the polling cycle without any voltage;
For recording the initial time of smi signal brown（Ta）And the recording module of current time (Tb);For calculating
The computing module of time duration between current time and initial time;
For judging whether time duration reaches the judge module of default overtime standard;
After reaching default overtime standard in judged result, the notification module of overtime notice is sent；
For removing the record of first flag value and or initial time, imply that first flag in poll point previous cycle
Value be reduced to default flag value and or the dump block that resets initial time；
And there is first flag value and the dump block in first in the previous polling cycle of one first poll point
After poll point removes first flag value, the first poll point and the second poll point of detecting voltage module monitors are low electricity
Position, and flag detecting module monitors the status information of its previous polling cycle in the second poll point, acquirement are indicated the
During the default flag value declined in the previous polling cycles of 2 poll points without any voltage, recording module records described second
Time corresponding to poll point records the initial time of smi signal brown for the recording module.
Especially, when high voltage occur in detecting voltage module monitors to poll point or flag detecting module monitors poll point
Previous polling cycle in when there is first flag value, dump block by first flag value in poll point previous cycle also
Originally it was to preset flag value and reset initial time.
Especially, the poll point that dump block is reset is the end poll point for judging time duration, tired after clearing
Timing length will recalculate, if not occurring initial time before the poll point reset, terminate at poll point, when not producing accumulative
It is long；If having there is initial time before the poll point reset, terminate at poll point, the not up to default overtime standard of time duration.
The present invention also provides a kind of monitoring method of smi signal overtime, and BIOS is monitored by way of poll by BMC
The smi signal that is transmitted of GPIO pin pin perform, it comprises the following steps:
Step S10:Polling cycle and default overtime standard are set, and the end points of polling cycle is poll point；
Step S20:Receive and start monitoring signal and monitored according to poll point；
Step S30:Whether the voltage for monitoring smi signal at current poll point is low-voltage, if so, performing step S40；Otherwise,
Perform step S50；
Step S40:Monitor the flag that voltage decline whether is produced in current polling cycle；If so, perform step S50；Otherwise, hold

In the present embodiment, the default overtime standard is 2 minutes.
In the present embodiment, BMC can note down the event that overtime notice occurs in the BMC in the form of SYSTEM LOG_SEL
In corresponding NVRAM.
Refer to shown in Fig. 3-5, by poll per second once, exemplified by default overtime standard is 2 minutes, according to the side of the present invention
Method can determine the 2nd poll point（I.e. the 2nd second）For SMI be triggered start start perform SMI the estimation time.
It is low-voltage at the 3rd poll point, the 4th poll point, the poll point of the 5th poll point ... the 122nd in Fig. 3, and the
When the first flag value that voltage declines being not present in each polling cycle before 122 poll points, BMC can remember the 2nd poll point
Record as Ta, each poll point afterwards is recorded as Tb, and continuous updating Tb, before the arrival of the 122nd poll point, because of Tb-
Ta<120 seconds, it can continue to monitor next poll point after the completion of the monitoring of current poll point, up to BMC polls to the 122nd poll point
When, Tb-Ta=120 second, then the 122nd poll point is terminates poll point, now, will send overtime notice.
It is low-voltage at the 3rd poll point, the 4th poll point, the poll point of the 5th poll point ... the 50th in Fig. 4, and the 50th
The first flag value that voltage declines is not present in each polling cycle before poll point, and is high electricity at the 51st poll point
Pressure, then the 51st poll point is to terminate poll point, time duration Tb-Ta=49<120 seconds, not up to default overtime standard, Bu Huifa
Go out overtime notice.
It is low-voltage at the 3rd poll point, the 4th poll point, the poll point of the 5th poll point ... the 91st in Fig. 5, and the 90th
The first flag value that voltage declines is not present in each polling cycle before poll point, and in the previous poll of the 91st poll point
The first flag value that cycle memory drops under voltage, then the 91st poll point is to terminate poll point, time duration Tb-Ta=89<120
Second, not up to default overtime standard, overtime notice will not be sent.
The mode with poll is interrupted in combination of the invention, and BMC only when receiving interruption (high voltage to low-voltage), remembers one
Individual flag, and during the mode for poll per second of arranging in pairs or groups is removed to check whether there is smi signal in being carrying out and existed, and this is carrying out
Smi signal brown is more than polling cycle, BMC is only in being carrying out and brown exceedes
The smi signal of one polling cycle carries out the detection of overtime, that is to say, that lasting detection this performed more than one poll
Whether the smi signal in cycle occurs overtime, rather than SMI occurs every time, and BMC carries out the inspection of overtime to each smi signal
Survey, so as to reduce the load of BMC interior operation times per second.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
