However, the raw data that is dumped cannot be used without parsing. This patchset is to improve the "perf report" support for SPE, and further process the data. Currently, support for the three events of llc-miss, tlb-miss, branch-miss and remote-access is added. The macro definition was modified under Jeremy's suggestion, and the "event:pp" approach was used under James' suggestion to achieve the precise ip of some events on arm64. Currently, only branch-misses are implemented, and other event support will be added later. In addition, we also found that when recording large multi-threaded programs, ctrl + c could not end recording, so it was fixed and two patches were added.
