Presented by Jiong Wang

This webinar will focus on eBPF JIT compilation infrastructure and how it plays an important role in the entire eBPF life cycle inside the Linux kernel. First, it does quite a number of control flow checks to reject vulnerable programs and then JIT compiles the eBPF program to either host or offloading target instructions which boost performance. However, there is little documentation about this topic which this webinar will dive into.

1. eBPF loader and ELF
2. eBPF verifier, control flow checks and security concerns
3. eBPF JIT compiler, code generation and performance
4. NFP-specific code generation and performance tuning
5. Emerging eBPF features to release more programming liabilities
6. Summary

Three common questions will be answered during the webinar:
Question 1: What's eBPF and why do we need a JIT compiler for it?
Question 2: Why it is critical to know the eBPF JIT compiler internals?
Question 3: How are Netronome's NFP and Agilio SmartNICs effectively supported by the eBPF JIT compiler?
