Embodiment Construction
[0020] The specific implementation manners of the present invention will be described in further detail below with reference to the accompanying drawings.
[0021] figure 1 According to an embodiment of the present invention, an overall architecture diagram of a computer system with a detection system unrecoverable error indication signal is shown. For example, a computer system herein may be a server. refer to figure 1 , the computer system with detection system unrecoverable error indication signal includes central processor units (CPU, Central Processor Unit) 101 and 103 , complex programmable logic device 109 , south bridge 111 and baseboard management controller 113 . When an unrecoverable error occurs in the computer system, the CPU unit 101 or the CPU unit 103 outputs an unrecoverable error indication signal. The complex programmable logic device 109 is electrically coupled to the CPU units 101 and 103 , and receives system unrecoverable error indication signals from...

The invention discloses a computer system for detecting unrecoverable error indication signal, and comprises a plurality of central process units (CPU), a complex programmable logic apparatus, a south bridge and a substrate management controller, wherein when the computer system is in unrecoverable error, at least one CPU outputs an unrecoverable error indication signal; the complex programmable logic apparatus is electrically coupled to the CPU; the south bridge is electrically coupled to the complex programmable logic apparatus; and the substrate management controller is electrically coupled to the complex programmable apparatus. When the unrecoverable error indication signal is divided into a signal pulse signal and a plurality of continuous pulse signals, the complex programmable logic apparatus correspondingly transmits the pulse signals to the south bridge or the substrate management controller so as to restart the computer system. By using the detection circuit provided by the invention, the indication signal can be transmitted to the south bridge or the substrate management controller according to the classes of the indication signals so as to output a restart command through the south bridge or the substrate management controller to restart the system.
Description
technical field [0001] The invention relates to a computer system, in particular to a computer system with a detection system unrecoverable error indication signal. Background technique [0002] At present, when the server system is running normally, some system errors in the running process may sometimes be encountered, which are classified according to whether these errors are recoverable, and generally include recoverable errors and unrecoverable errors. When recoverable errors occur, in order to improve the reliability of the server system, it is usually configured to capture these recoverable or correctable errors and write them to the error log when recoverable errors occur, using capture and log processing The program gives the user of the server system an opportunity to replace the defective memory unit and return the system to normal operation before the entire system crashes. However, when an unrecoverable error occurs, it indicates that the server system cannot c...
