eBPF Performance Boost: Unveiling the Trampoline Mechanism
2025-08-11
This blog post delves into the eBPF trampoline mechanism, a key performance optimization. With eBPF's increasing use in system monitoring and other areas, efficient program execution is critical. The trampoline avoids the overhead of exception handling in traditional kprobe methods by directly calling eBPF programs. The article details the trampoline's inner workings, covering advanced use cases like handling function entry and exit points, multi-argument passing, and implementation optimizations on ARM64.
