Tags: linux kgdb debuggingby Pingbo Wen of tinylab.org2013/08/11Brief introductionThis document records the entire process of debugging the Linux kernel with KGDB, which is a summary of the predecessors ' work. The following actions are based on a specific board, but most of them can be applied to other platforms. To d

Linux Kernel analysis uses GDB and QEMU for debugging-Linux general technology-Linux programming and kernel information. The following is a detailed description. During Linux

The kernel header file Include/linux/kernel.h describes the prototype of the tool functions provided by ftrace, including TRACE_PRINTK, Tracing_on/tracing_off, and so on. This article shows readers how to use these tool functions in code through the sample module program.Print trace information using TRACE_PRINTKFtrace provides a tool function for outputting trace information to the Ftrace trace buffer, cal

module, at the terminal casually knock a few commands to trigger the process to create, the kernel print out the above message, you can see the do_fork of the entry is very easy to obtain, and other functions of the probe is similar, no longer described in detail.2, Jprobe realization AnalysisThe implementation of Jpeobe is based on kprobe, so this will be in the previous post "Linux

In order to grasp how a custom kernel function is executed, some debugging methods are required. In fact, a tracing method is required, which is not very complex in theory, however, there are too many debugging interfaces in the Linux kernel, and it cannot be found easily un
