Description
Technical field
The present invention relates to computer processor overheat protector technical field, specifically a kind of excess temperature protection method based on Loongson processor.
Background technology
External processor, as Intel general processor, the internal temperature of CPU the internal temperature of CPU can be sent to monitoring management system constantly by PECI bus, also has special function PIN to send a signal to system, make system closedown power-off when temperature reaches threshold values.
But domestic server---Godson CPU does not have above-mentioned functions, very large inconvenience is brought to monitoring management, wonder the internal temperature of Godson CPU, traditional way is the value that BIOS constantly must remove the internal temperature register of poll CPU, a large amount of system resource can be wasted like this, reduce CPU work efficiency, so both affect CPU usefulness, easily cause again CPU to damage because temperature is too high
Summary of the invention
Technical assignment of the present invention solves the deficiencies in the prior art, provides the excess temperature protection method that a kind of work efficiency is high, fully can discharge Loongson processor work load.
Technical scheme of the present invention realizes in the following manner; this a kind of excess temperature protection method based on Loongson processor; comprise the server of built-in Loongson processor, this Loongson processor is connected with monitoring management unit B MC by lpc bus, and it specifically protects process to be:
1) threshold temperature of Loongson processor work is set by BMC;
2) BMC collects the external temperature of Loongson processor;
3) when this temperature reaches above-mentioned steps 1) in setting certain threshold values time; BMC sends interrupting information to Loongson processor, and Loongson processor feeds back its internal temperature information to BMC, when exceeding overheat protector temperature maximum; trigger forced shutdown instruction immediately, complete overheat protector.
Threshold values in described step 1) refers to the temperature value that Loongson processor can bear: generally sequentially arrange N number of by this temperature value, wherein N number of maximum temperature that can bear for Loongson processor.
Described step 2) in the external temperature collection process of Loongson processor be: arrange a thermistor at the back side of Loongson processor, this thermistor is connected with BMC by Smbus bus after being transformed in analog to digital converter by dividing potential drop mode.
The specific implementation process of described step 3) is: after the Loongson processor external temperature that BMC obtains, compare with N-1 threshold values of setting, if external temperature is greater than this threshold values, then BMC sends an interruption to Loongson processor, Loongson processor response is interrupted and the numerical value of its internal temperature register is sent to BMC, compares, when the temperature obtained is higher than N number of threshold values after BMC obtains this temperature value with N number of threshold values, BMC sends shutdown command immediately, forced shutdown.
The beneficial effect that the present invention is compared with prior art produced is:
A kind of excess temperature protection method based on Loongson processor of the present invention carries out analyzing and processing by monitoring management unit B MC to temperature data; if the mxm. that temperature can bear more than CPU will close whole system; can not only effectively prevent CPU from damaging because temperature is too high like this; and access by the mode of interrupting the work load that CPU fully can discharge Loongson processor; ensure that domestic server security effectively runs; neither affect CPU usefulness, can prevent again CPU from damaging because temperature is too high.
Accompanying drawing explanation
Accompanying drawing 1 is Loongson processor internal temperature of the present invention and external temperature corresponding relation figure.
Accompanying drawing 2 is one-piece construction schematic block diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing, a kind of excess temperature protection method based on Loongson processor of the present invention is described in detail below.
As shown in accompanying drawing 1, Fig. 2, this kind of excess temperature protection method based on Loongson processor, comprise the server of built-in Loongson processor, this Loongson processor is connected with monitoring management unit B MC by lpc bus, and it specifically protects process to be:
1) because the internal temperature of CPU must be higher than external temperature, so set the threshold temperature of Loongson processor work by BMC, this threshold values and CPU internal temperature one_to_one corresponding, like this by the temperature spot of CPU outside, corresponding internal temperature point can be found, as shown in Figure 1, temperature value is arranged to 5 threshold values from low toward height here: T1, T2, T3, T4, T5, wherein T5 is the maximum temperature that Godson CPU can bear.
2) BMC collects the external temperature of Loongson processor, concrete collection process is: put a thermistor NTC at the back side of Loongson processor, this thermistor NTC is connected with BMC by Smbus bus after being transformed in analog to digital converter by dividing potential drop mode, here the HWMonitor in analog to digital converter and figure, the converter that described HWMonitor can use model to be W83795, BMC by SMbus with the temperature value of the mode of poll from HWMonitor Real-time Obtaining CPU back.
3) when this temperature reaches above-mentioned steps 1) in setting certain threshold values time; BMC sends interrupting information to Loongson processor, and Loongson processor feeds back its internal temperature information to BMC, when exceeding overheat protector temperature maximum; trigger forced shutdown instruction immediately, complete overheat protector.Its specific implementation process is: after the Loongson processor external temperature that BMC obtains; compare with the T4 threshold values of setting; if external temperature is greater than T4; illustrate that now cpu temperature is higher; be necessary to obtain the inner real temperature data of CPU; and send look-at-me to CPU; Loongson processor response is interrupted and the value of now temperature register is fed back to BMC by lpc bus; if the temperature value that BMC obtains is greater than T5; illustrate that now cpu temperature can not accept; there is the risk of burning CPU, close whole system immediately, protection CPU.
Pass through the method, system the mode of obstructed overpolling can access CPU constantly, just when CPU external temperature reaches the threshold points set in advance, monitoring management unit B MC just sends interruption to CPU, CPU sends BMC temperature information to by lpc bus, monitoring management unit B MC carries out analyzing and processing to data, if the threshold values that temperature can bear more than CPU will close whole system; Can not only effectively prevent CPU from damaging because temperature is too high like this, and access by the mode of interrupting the work load that CPU fully can discharge Loongson processor, ensure that domestic server security effectively runs.
