Kernel debugging with Kprobes (IBM developerWorks)
IBM developerWorks shows
how to use Kprobes to debug the Linux kernel. "The benefits of
using Kprobes are many. printk's can be inserted without rebuilding and
rebooting the kernel. Processor registers can be logged and even modified
for debugging -- without disruption to the system. Similarly, Linux kernel
data structures can also be logged and even modified non-disruptively as
well. You can even debug race conditions on SMP systems with Kprobes -- and
save yourself the trouble of all that rebuilding and rebooting. You'll find
kernel debugging is faster and easier than ever."
