BPF Performance Tools: Linux System and Application Observability (book)
Sorry, I usually do but missed it this time. However, it's been discussed recently that we are making BPF a technology name and not an acronym, because the acronym is misleading to new users. As a new user yourself, would you be satisfied with "BPF is a technology name and not an acronym" without ever expanding it? (Because the instant we do, we've confused you further.) I get that expanding acronyms gives you a 3-word summary of a technology, so in that case, it should expand to: Generic Kernel Runtime (but that's not BPF! I know, that's the whole problem!) Historically, BPF stands for Berkeley Packet Filter, but none of those words help you understand what it does. It's a generic kernel runtime, just like the JVM or v8.
