[0036] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.
[0037] In order to solve the defects of the above-mentioned several traditional driver debugging methods, the present invention analyzes the deficiencies of the prior art, and provides a method of using GDB to debug the driver under the operating system. At present, the reasons why the GDB program cannot debug the driver include the following:
[0038] 1. GDB programs cannot debug kernel modules.
[0039] 2. The GDB program cannot debug the IO interface provided by the operating system to the driver.
[0040] 3. The GDB program cannot debug the interrupt service routine.
[0041] Therefore, if you want to use GDB to debug the driver, you need to solve the above three problems.
[0042] The solution idea of the present invention is:
[0043] Transform the kernel-mode driver ontology into user mode, and adopt the idea of intermediate thre...
