Tanel Poder @tanelpoder.com · Aug 21 This is what I'm currently playing with: *Passive sampling* of hardware interrupt stacks with eBPF. With xintr, you'll soon be able to see inside your interrupt activity even on cloud VMs without hardware performance counters and without kernel probe & tracepoint overhead! Demo link in replies.

- A small demo asciicast is here: asciinema.org/a/734843 - xintr is already available in the 0x.tools repo (xstack/xintr.*) but it's an early prototype that I plan to rewrite, once everything makes sense to me :-)
