DESCRIPTION:This session dives into the core mechanisms of Linux kernel tra
 cing. \nWe explore dynamic instrumentation such as exception-based kprobe 
 and code-patching ftrace\, comparing internals and performance overhead. \
 nThe talk also covers low-overhead\, statically defined tracepoints and co
 unter-based sampling via perf_event. Finally\, we introduce BPF as a progr
 ammable execution layer that reuses and enhances tracing sources for flexi
 ble and efficient kernel observation.
