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.
