AI Technical Summary

Problems solved by technology

Otherwise, if the requested resources are not recovered in time, it will not be conducive to the system to provide subsequent services, and may cause memory resource leakage, system deadlock or even crash.
[0004] To sum up, regardless of the resource release when unloading the driver device or the resource release during error handling, after the resource is released, due to the incompleteness of the artificial resource release and the unfixed time, it will lead to pending release. Resources cannot be completely released, which in turn causes system resources not to be recovered in a timely manner, which is not conducive to the provision of follow-up services of the system

Abstract

The invention discloses a drive resource recycle analyzing method. The method comprises the following steps of obtaining trigger instructions for releasing resources, releasing corresponding resources in a resource list according to the trigger instructions for releasing the resources, determining whether omitted resources of the released resources exist in the resource list or not after the corresponding resources in the resource list are released, and reporting the information of the omitted resources if the omitted resources of the released resources exist in the resource list. According to the drive resource recycle analyzing method, a system detects resources used in drive equipment periodically, recycling of the resources is achieved, and leakage of internal storage resources is further avoided.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for recovering and analyzing drive resources. Background technique [0002] In the existing operating system, the driver device needs to call a large number of kernel interfaces to complete the operation and management of resources, but errors and exceptions will also occur during the operation of the driver device, so it is necessary to unload the loaded driver. It is necessary to release the resources requested by the drive device and roll back the successful operation. For example, release the requested memory and close the open device. [0003] In the existing technology, the resources used by the driving device can be directly located through the kernel interface function. For the handling of errors and exceptions, it specifically includes: manually analyzing the functions called during the process from loading the drive device to sending errors or exceptions, and analyzi...
