Detection method and system of non response during interruption

Abstract

The invention belongs to the computer technological field and provides a detection method and a system of non response during an interruption. The method includes reading data in abnormal entry addresses, obtaining entry addresses of an excNormVec function through a system symbol table; reading the data of the entry addresses till the end of the function; and comparing data read in the abnormal entry addresses with data read in an excNormVec entry address till data of the end of the function are identical, wherein if the data are identical, an abnormal distribution function is analyzed to be capable of working normally; and if the data are not identical, the abnormal distribution function is analyzed to be not accurately placed in an abnormal entry point, an error message is output, and an error point is reported. According to the detection method and the system of non response during the interruption, development efficiency and diagnosibility can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a detection method and system for interrupt non-response. Background technique [0002] At present, there is no analysis and solution for interrupts or exceptions that cannot be responded to under the MIPS architecture CPU. [0003] The closest existing technical solution is to locate the cause of the exception in the software code. The idea is to trace back the call stack of the function where the exception occurs according to the currently generated exception information, and then trace the function call path to analyze the cause of the exception. However, the function where the exception occurred may be called by a different function. [0004] The scheme of the call stack of the backtracking function is as follows: [0005] Step 1: In the exception handler, read the EPC register of CP0 to obtain the address of the instruction that caused the exception, which is...

Problems solved by technology

[0014] The purpose of the present invention is to provide a detection method and system for interruption and non-response, aiming to solve the problem in the prior art that if the interruption or abnormality cannot enter the exception handling program, it is impossible to locate the real cause of the abnormality, even if it can Entering the exception handler also requires manual analysis of the real cause of the exception
