Linux Plumbers Conference 2014 Refereed Talks

Proposals for this user

* Ftrace kernel hooks, more than just tracing (Confirmed)

The audience is aimed at developers. You do not need to be a kernel developer to enjoy this talk. Just someone that enjoys the art of programming and the crazy ideas that are performed to overcome such obstacles. Live code modification is not trivial, and now the new features of allocating code on the fly makes it even more radical. This is not a trivial task; it requires understanding how the CPU pipeline works as well as all states that the kernel can be in. (slides)
