eBPF Documentary

   dtrace for linux - kernel driver and userland tools (by dtrace4linux)

   > I'm referring to the fact the eBPF will be available across Microsoft, Apple, and Linux, and there is no other technology that will be able to offer that.

   I don’t know if there’s some qualification im missing in your statement, but does this not count?

3. bcc

   2 79 20,904 9.0 C

   BCC - Tools for BPF-based Linux IO analysis, networking, monitoring, and more

   

   One of the big wins is not so much “build and run your own stuff” but there are very nice low-cost (in terms of compute) performance utilities built on eBPF

   https://github.com/iovisor/bcc

   There are so many utilities in that list; there’s a diagram midway down the readme which tries to help show their uses. bcc-tools should be available in any distro.

   Also, Brendan Gregg does a ton of performance stuff that is worth knowing about if you check out his other work. Not eBPF only. Flame graphs are useful.

4. illumos-gate

   3 36 1,693 9.6 C

   An open-source Unix operating system

   

   It may become a footnote on Linux, but Linux isn't the only system out there -- and DTrace remains alive and well in many systems (not least in its reference implementation in illumos[0]).

5. genode

   4 22 8 0.0 C

   Genode OS Framework

   

6. gobpf

   5 2 2,151 0.0 C

   Go bindings for creating BPF programs.

   

   This [1] makes me think gobpf uses C bindings to bcc, so golang does not compile to eBPF, bcc does.

7. ebpf

   6 9 6,560 9.4 Go

   ebpf-go is a pure-Go library to read, modify and load eBPF programs and attach them to various hooks in the Linux kernel.

   

   Oh, no I don't mean that arbitrary Go compiles to eBPF. Apologies if I gave that impression. I meant that there are libraries that let you compose eBPF programs in other languages. But you're still putting together an eBPF program, just like you can assemble JSON with Go but you can't compile an arbitrary Go program to JSON.

   Cilium's eBPF library is the Go one I had in mind: https://github.com/cilium/ebpf

   Here's an example from that repo: https://github.com/cilium/ebpf/tree/main/examples/ringbuffer
