Kdump is a fundamental component for debugging Linux kernel panics. And by design, it requires to pre-reserve a chunk of continues physical memory. It's been a long time issue to keep the balance between minimizing the memory usage and avoiding OOM during kdump. In this session, the speaker will share some techniques and new tools that were used to analyze and minimize the memory usage in kdump, which will also be useful for other tighten environment like embedded systems. And also, the speaker will share about current ongoing works in this area.
