Embodiment Construction

[0029] The present invention proposes a new debugging architecture in order to overcome the shortcoming that ordinary debuggers cannot debug and run programs in the operating system kernel state. As shown in Figure 1, the debugging system architecture specifically includes: designing a kernel debugging pile 11, and the debugging pile 11 runs in kernel mode. The foreground debugging agent 12 communicates with the debugging stub 11 , and the debugging stub 11 controls the operation of the kernel thread 13 . The kernel thread 13 feeds back the abnormal information to the debugging stub 11 when encountering an abnormal event, and the debugging stub 11 returns the information to the foreground debugging agent 12 after receiving the abnormal information, and the foreground debugging agent 12 receives the message and returns it to the debugger 14. Therefore, the common user mode debugger 14 can be used to debug the program in the kernel mode, which facilitates the development of the...

Abstract

A method for debugging kernel state of operation system includes making foreground debug agent module communicate with debug picket module by setting debug picket module in kernel state and said agent module in user state, receiving debug information by debug picket module to control kernel linear program operation and to obtain abnormal information of kernel linear program, sending abnormal information to debug picket module then sending it to foreground agent module furthermore returning it back to debugger for carrying out debugging on kernel state program.

Description

technical field [0001] The invention relates to a method and a device for debugging an operating system kernel state program, in particular to a method and a device for debugging a kernel state program by using an ordinary debugger. Background technique [0002] For security reasons, the operating system has designed two running states for the program: user state and kernel state. Ordinary applications run in user mode, and some special programs and the operating system itself run in kernel mode. The current debugger is designed to debug user-mode programs. For kernel-mode programs, only printing or dedicated chip debugging interfaces can be used for debugging. The disadvantages are: [0003] 1) Using the printing method actually has no debugging function, and the printing statement is completely imitated based on experience, and must be recompiled every time, resulting in low debugging efficiency. [0004] 2) The method of using the dedicated chip debugging interface is r...
