Hello all,
We had a small catch-up meeting with three participants. There weren't
any major action items or pressing topics to discuss, but here are some
notes:
* As mentioned, LPC is coming up. Remote attendance is an option too.
I'm not sure whether the MC is accepted or just "proposed" - it's
possible that talk submissions will be folded into Toolchains if we
don't have enough to fill a full track for a day.
* Philip mentioned some open questions he's been thinking about: Rust
support for Linux debugging tools, especially crash (and Drgn will
need to think about this as well).
* Jay mentioned that the C++ support work for Drgn has laid a lot of
groundwork that should hopefully make this easier, specifically with
a few DWARF tags which weren't implemented.
* As a novice with DWARF, I asked about resources for learning more
about it. Jay mentioned that the DWARF spec is the best resource, but
doesn't recommend it for learning -- he suggested playing with
"dwarfdump" on a simple program to get my feet wet.
* I shared a demo of Drgn running on a live kernel with CTF data, and no
DWARF info. As of now, CTF debuginfo is not a feature in the upstream
build system, so I'm demonstrating Oracle UEK, which carries CTF as a
distribution patch.
* Relating back to Rust for Linux, it will be interesting to see how
CTF can adjust to the Rust type system. Similarly, BTF will have to
start considering this as well.
Thanks for the folks who showed up! It was good to see everyone, and
I'll be looking forward to the June meeting, when we should be back to
normal with Omar hosting.
Thanks,
Stephen
