Explore the development of an eBPF profiler for polyglot cloud-native applications in this 32-minute conference talk from the Linux Plumbers Conference. Dive into the intricacies of profilers, stack traces, and the challenges of disabling frame pointers. Gain insights into kernel debugging, return address analysis, and working without frame pointers. Examine the architecture of the profiler, including unwind rows, data parsing, and BBF programs. Learn about binary search techniques and the WBF unwinder. Conclude with a discussion on future plans for this innovative profiling solution.
