DAMOS quota auto-tuning asks users to assess the current tuned quota and provide the feedback in a manual and repeated way. It allows users generate the feedback from a source that the kernel cannot access, and writing a script or a function for doing the manual and repeated feeding is not a big deal. However, additional works are additional works, and it could be more efficient if DAMOS could do the fetch itself, especially in case of DAMON sysfs interface use case, since it can avoid the context switches between the user-space and the kernel-space, though the overhead would be only trivial in most cases. Also in many cases, feedbacks could be made from kernel-accessible sources, such as PSI, CPU usage, etc. Make the quota goal to support multiple types of metrics including such ones.
