====Improving tracing in perf events / ftrace====
===(an idea from a student)===

Using trace events under perf events is still a young feature and needs various improvements.

  * Syscall events can carry only raw values and addresses. We need to make them "aware" of strings and structure contents from userspace.
  * Make function / function graph tracers usable by perf.
  * Optimize tracing fast-path.
  * Improve perf tools to better handle trace events scalability.
  * Provide new perf tools that exploit trace events (scheduler\\ 
    migration analysis, etc...).
  * Implement a per context excluding (eg: exclude irqs, exclude functions, etc...).

Of course, each of these elements can require a lot of work; probably the whole task list cannot be completed during the GSOC period, so for a single student it will be enough to complete only some of the items.\\ \\ \\ \\ \\ \\ \\ \\
