Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.

[0039] like figure 1 As shown, the hardware device error detection method of the present invention includes the steps of: S1: detecting the error that the hardware device continues to interrupt; S2: detecting the error that the hardware device does not generate an interruption.

[0040] like figure 2 As shown, it is a flowchart of error detection of continuous interruption in an embodiment of the present invention, including the following steps:

[0041] Step S101, setting the global variable count in the device driver code, initializing the global variable count to 0 in the device driver initialization subroutine, and initializing and setting a timer in the device driver initializatio...

Abstract

The invention relates to a hardware equipment error detection method, which comprises the following steps of detecting continuously interrupted errors of hardware equipment; and detecting errors without occurrence of interruption of the hardware equipment. The continuously interrupted errors and the errors without occurrence of interruption of the hardware equipment are detected through the hardware equipment error detection method, and driving reliability of the equipment can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of computers and electronic information, in particular to a hardware device error detection method. Background technique [0002] Reliability is an important goal of an operating system. 85% of Windows XP operating system failures are caused by device drivers. The failure frequency of Linux operating system device drivers is more than 3-7 times that of other parts. Research shows that device failure is the leading cause of operating system failure. A study of Windows servers found that 8 percent of system storage devices or network adapters would fail. 9% of servers were forced to reboot due to hard disk or network adapter failures. Therefore, it is of great significance to check the error of the device in the device driver to improve the reliability of the operating system. Sustained interrupts and no interrupts are typical device errors. Sustained interruption means that the hardware device keeps tri...
