The drgn Python-based kernel
debugger was developed by Omar Sandoval for use in his job on the kernel
team at Meta. He now spends most of his time working on drgn, both in
developing new features for the tool and in using
it to debug production problems at Meta, which gives him a view of both
ends of that feedback loop. At the 2023
Linux Plumbers
Conference (LPC), he led a session on drgn in the kernel debugging
microconference, where he wanted to brainstorm on how to add some new
features to the debugger and, in particular, how to allow them to work on
production kernels.
