Linux Kernel Debugging Tools Monthly Meeting on Wednesday, February 18th

The next Linux Kernel Debugging Tools meeting is this Wednesday, February 18th at 11:30 AM Pacific time. This meeting is a forum to discuss development of Linux kernel debugging tools like drgn, crash, and more.

Here is the agenda so far:

- drgn release this week.

Reminder: I will be out of the office from February 23-March 27.

Please reply with anything else you'd like to add. As always, if you would like to attend, please email me offlist.

If content is light, I'd be happy to share progress on the BTF implementation, which is working quite nicely. Upstream kernels are still missing type entries for global variables, but that's actually pretty easily sidestepped for a lot of cases, so it can be practically useful even with that limitation. It could be interesting to discuss ideas about how to properly test it in vmtest.

If we can get something useful with BTF merged even with the current state of kernel BTF, that would be a major factor to share upstream with the BPF community to motivate adding global variable support in one way or another.
