Hi SJ, Thanks for the roadmap update. This direction makes sense to me. I plan to align the Arm SPE extension with the common damon_report_access()/data-attribute infrastructure and coordinate it with the AMD IBS work, rather than developing a separate interface. I will follow the upcoming patches and would be happy to help review and test the common infrastructure and the IBS series. I will also track the remaining work needed to bring the SPE support upstream. I would also be happy to take on some related implementation work. For my earlier DAMOS_SPLIT work, I am now preparing v4 with this direction in mind. We are designing representative workloads, collecting data, and exploring a few design options before deciding the exact shape of the next revision. Thanks, Lian
