SK Hynix HMSDK presentation video at OSSummit Korea is now available: https://sched.co/2913n

As a part of the talk, HMSDK's CXL memory capacity expansion, which utilizes DAMON internally, is also introduced. It provides detailed explanation of design, their test setup, results, and even a multi-threads based tuning tip. Especially the evaluation using an LLM workload is impressive to me.

Also, this gives me a motivation for unifying the capacity and bandwidth expansion solutions. I may share a thought soon on the mailing list.

> this gives me a motivation for unifying the capacity and bandwidth expansion solutions. I may share a thought soon on the mailing list.

Just posted a rough and early idea about how to provide a holistic tiered memory management for both capacity (or, latency) and bandwidth: https://lore.kernel.org/all/20251114014255.72884-1-sj@kernel.org/

FYI, I got the idea from a chat with a dynamic interleaving developer at Micron, as I also noted on the mail, and HMSDK talk gave me more motivation to develop it.
