Embodiment Construction

[0021] The following will be combined with figure 1 The method of the present invention is further described in detail.

[0022] The test method invented by the present application mainly utilizes python scripts for automatic error annotation and automatic analysis of results.

[0023] First install the ITP tool on the server;

[0024] Set the server memory RAS function;

[0025] Continuous error injection test is carried out on the server memory subsystem. The specific implementation method is to use ITP tool to simulate memory continuous

[0026] An ECC error occurred;

[0027] Judging whether the annotation error exceeds the threshold;

[0028] If the threshold is not exceeded, the error injection test is repeated until the set threshold is exceeded;

[0029] If it exceeds the threshold, check whether the information of the register corresponding to the memory has changed. If so, it proves that the RAS function of the server memory is working normally; if there is no c...

Abstract

The invention relates to the field of server testing, in particular to a method for automatically testing RAS characteristics of a memory in an X86 platform. The method comprises the steps of performing continuous fault injection testing on a memory subsystem by using an ITP testing tool of an Intel platform, until a threshold is exceeded; and then according to function item settings of RAS, checking whether corresponding register information is changed or not, thereby judging whether the RAS characteristics take effect or not. The method for testing the RAS of the memory is convenient in useand simple in operation, and can effectively shorten product development time of a test link and reduce a probability of misoperation of test personnel.

Description

technical field [0001] The invention relates to the field of server testing, in particular to a method for automatically testing memory RAS characteristics on an X86 platform. This method uses the ITP test tool of the Intel platform to continuously test the memory subsystem until the threshold is exceeded. After the error exceeds the threshold, the log generated by the error is redirected to a file. According to the function item setting of RAS, Check whether the corresponding register information changes, so as to judge whether the RAS feature takes effect. The method for testing memory RAS is easy to use and simple to operate, can effectively save product development time in the testing process, and reduce the probability of misoperation by testers. Background technique [0002] X86 is a complex instruction set introduced by Intel, which is used to control the operation of the chip. Now X86 has been widely used in the field of home PCs. The X86 architecture first appeare...
