Hello DAMON community, Already the first quater of 2024 has passed. Meanwhile, there were some exciting news on DAMON community. Let me share my humble summary of those. Januarry 2024 ============= Memory management subsystem pull request[1] for Linux v6.8-rc1 that contains aim-oriented user-feedback driven DAMOS aggressiveness auto-tuning has merged. SK Hynix shared[2] their DAMOS-based tiered memory management test results showing 4-17% performance slowdown reduction, with patches for that. LSF/MM/BPF 2024 topic proposal for DAMON has posted[3]. February 2024 ============= DAMON in Amazon Linux 5.10.y kernel[4] has updated to that of v6.7 Linux kernel. DAMON talk for OSSummit NA 2024 has been accepted and scheduled[5]. DAMO v2.2.2 is released with a new command, 'replay'[6]. It is aimed to help reproducing the real-world memory access pattern for analysis and benchmarks. Yet another academic paper[7] exploring DAMON for tiered memory management will be presented at EuroSys 2024[8]. March 2024 ========== DAMO v2.2.4 is released with a new feature for access pattern-based profiling[9]. Users can know which code is making their program's memory usage unexpectedly high, or which code is intensively accessing memory, and optimize. DAMON maintainer received the invitation for LSF/MM/BPF 2024. Memory management subsystem pull request[10] for Linux 6.9-rc1 that contains aim-oriented self-feedback driven DAMOS aggressiveness auto-tuning has merged.

More people from the academy and the industry explored and contributed on DAMON. DAMON user-space tool got more useful features. We will have yet another DAMON presentation and discussion at OSSummit NA and LSF/MM/BPF. It was a grateful quarter. Looking forward to next news of the second quarter. Happy second quarter and hacking, community! Thanks, SJ
