Detailed information about KGDB is available on the pageUsing kgdb, kdb and the kernel debugger internalsin theLinux Kernel Archives. Using KGDB requires a host system with a serial connection to the target device to be debugged. This allows live source-level debugging of kernel operati...
NVIDIA® Jetson™ Linux lets you generate a kernel crash dump, which is a portion of the system’s volatile memory (RAM) saved to disk when the execution of the kernel is disrupted. The following events can cause such a disruption:Kernel...

Linux Kernel Debugging Overview This page gives an overview of Linux debugging process used by VisualKernel and explains different methods that can be used to debug your kernel. Debugging a Linux kernel always involves two machines: one machine running the kernel itself (Target machine) and another...
This tutorial shows how to use the Live Trace feature of VisualKernel 4.0 to easily record the kernel debugging sessions without having to stop the target. We will create a basic character device, record the calls to itsread()handler, and will also show how to set tracepoints in arbitrary ...
