Beyond traces per cpu, uftrace expect to find some specific files. - info: contains information about machine/program run those values are not impacting uftrace behaviour (only reported by uftrace info), and we simply added empty strings. - memory mapping: how every binary is mapped in memory. For system mode, we generate an empty mapping (uftrace_symbols.py, coming in future commit, will take care of that). For user mode, we copy current /proc/self/maps. We don't need to do any special filtering, as reported addresses will necessarily concern guest program, and not QEMU and its libraries. - task: list of tasks. We present every vcpu/privilege level as a separate process, as it's the best view we can have when generating a (visual) chrome trace. Using threads is less convenient in terms of UI.
