It tries to address all the requirements discussed in : https://marc.info/?l=linux-kernel&m=148891934720489 -basically to monitor resctrl groups / per thread including kernel threads. -monitor thread from creation (also a child thread forked belongs to same group like its parent) -monitor subset of tasks in a resctrl group. -monitor subset of cpus in a resctrl group. -monitor different events (however the first version only shows llc_occupancy) -monitor all domains and show per domain data. I have a patch series but was thinking to send after the design document is reviewed so that its easy to review and I can make changes that are discussed here.
