Meeting notes: - We discussed whether we wanted to do another Linux kernel debugging microconference at Linux Plumbers Conference this year. The consensus was no, at least for this year -- instead, we'll do some BoFs to share debugging demos and tips. If we do decide we want some microconference discussions, we can submit them to the tracing microconference. - Neal Gompa brought up the lack of educational content about debugging. This is a problem we're all acutely aware of, but many of us who are knowledgable enough to create such content tend to be busy developing the tools instead. Help is needed here. - We discussed sframes, and particularly how to avoid distros and tooling stripping them, which tied into education. - I shared that the drgn module API is nearing completion. The two biggest missing pieces are documentation and ELF symbol support. Stephen Brennan shared that he already had code for kallsyms that could be adapted for ELF symbols. - Stephen Brennan discussed his latest drgn PR for DWARFless debugging: https://github.com/osandov/drgn/pull/388. - We discussed replacing our Slack workspace with an open source alternative. With some helpful input from Neal Gompa and Jay Kamat, we decided that Matrix would be a good fit. Given the low traffic of our workspace, we will start with a single Matrix room for everyone (developers and users), and we can split it up as needed. I'll share an update on the linux-debuggers mailing list when it's set up. See everyone next month!
