Description
DAMON is a kernel subsystem for efficient data access/attributes monitoring and memory operations. It received many updates last year. Many more updates are in progress. Multiple ideas for future works are flooding. In this session, multiple people who work on DAMON will present and discuss what changes have recently been made, what changes are ongoing, and what should be the next work.

Authors (Alphanetically sorted)
Akinobu Mita
Software engineer at Fixstars Corporation.
Asier Gutierrez
Senior Software Engineer at Huawei. Experienced Senior Software Developer specializing in Linux development, kernel-level debugging, and high-load, high-availability systems. I currently work for Huawei. I have worked for Intel, IBM and Yandex in the past.
Krishna Iyer
Krishna Iyer is a Software Engineer at Crusoe specializing in low-level systems, driver development, and Linux build systems. Previously at Cisco-Meraki, he now focuses on researching memory access patterns using DAMON for AI workloads on GPU infrastructure.
Kunwu Chan
Kunwu Chan works on the Linux kernel, with a focus on DAMON, huge pages, swap, and RCU.
Lian Wang
Lian Wang is a Software Engineer at Process Mission (Shanghai) Technology Co., Ltd. He works on Linux kernel memory management, with a focus on DAMON, huge pages, and memory management for virtualized and large-memory Systems.
Ravi Jonnalagadda
Ravi Jonnalagadda is a Sr Manager at Micron working on Linux kernel memory management for CXL and tiered-memory systems. He co-developed the weighted interleaving memory policy and added the node_eligible_mem_bp DAMOS quota goal. His current work lets DAMON take access samples from hardware sampling units.
SJ Park
SJ is a kernel programmer with a strong focus on memory management. He develops and maintains DAMON, a Linux kernel subsystem designed for efficient data access monitoring and access-aware system operations.
