Kernel Debugging Profiling Pdf ”everyone knows that debugging is twice as hard as writing a program in the first place. so if you’re as clever as you can be when you write it, how will you ever debug it?”. Discover valuable strategies and tools for debugging in the linux kernel environment. learn about common bug types, debugging pitfalls, and the essential support built into the kernel. Os debugging free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. This session aims to merge the work we have done up until now in the kernel space with real world use cases where we do not write kernel space code, but we look through the kernel using profiling tools, in order to debug issues that we're having when writing regular, low level, applications.
