Currently there's only tracefs_tracers() which only give the top level tracers, but instances may have a limited set. - tracefs_synth_set_instance() to set the instance that does the work to make the synthetic event such that the histograms it uses does not affect the top level or other instance. - tracefs_find_cid_pid() helper used to map the main guest thread to a given vsocket CID. - tracefs_time_conversion() helper function that does a perf system call to find out what the multiplier and shift that the kernel uses to calculate nanoseconds from the CPU time stamp counter. - tracefs_kprobe_destory() used to complement tracefs_kprobe_raw() and tracefs_kretprobe_raw(), as those do not return descriptors that can be used to delete the kprobe and kretprobe. Updates: - Fixes to the tests. - Added meson build support (but it is not the default). https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/ Enjoy! -- Steve
