Adding Inter-event Capabilities to Linux Kernel Trace Events

Explore the intricacies of enhancing Linux kernel trace events with inter-event capabilities in this informative conference talk. Delve into the Linux kernel trace event subsystem and its extensive array of tracepoints, learning how to extract inter-event quantities such as latencies without relying on external logic. Discover a general-purpose mechanism for deriving inter-event values from arbitrary event sets, and see how it can be applied to create one-off experiments and advanced tools like latency histograms. Gain insights into enabling and triggering events, understanding latency issues, and working with synthetic events. Follow along as the speaker covers topics including variables, recursive events, and arithmetic operations within the context of kernel tracing. Enhance your knowledge of Linux kernel development and tracing techniques to improve system performance and debugging capabilities.
