I checked and this hasn't hit mainstream, is it already merged on a tree where this is slated to be submitted in the next window? If so please let me know which one so that I can merge it on perf/core. - Arnaldo > L2 - local L2 > L2 | REMOTE | HOPS_0 - remote core, same node L2 > L2 | REMOTE | HOPS_1 - remote node, same socket L2 > L2 | REMOTE | HOPS_2 - remote socket, same board L2 > L2 | REMOTE | HOPS_3 - remote board L2 > > Patch 1 & 2 adds tool and kernel side changes to add new macros for > mem_hops field > > Patch 3 add data source encodings for power10 and older platforms > to represent data based on newer composite PERF_MEM_LVLNUM* fields > > Patch 4 add data source encodings with proper sub_index used to > represent memory/cache level data for power10 platform. > > Kajol Jain (4): > perf: Add new macros for mem_hops field > tools/perf: Add new macros for mem_hops field > powerpc/perf: Add encodings to represent data based on newer composite > PERF_MEM_LVLNUM* fields > powerpc/perf: Add data source encodings for power10 platform > > arch/powerpc/perf/isa207-common.c | 60 ++++++++++++++++++++------- > include/uapi/linux/perf_event.h | 5 ++- > tools/include/uapi/linux/perf_event.h | 5 ++- > tools/perf/util/mem-events.c | 29 ++++++++----- > 4 files changed, 71 insertions(+), 28 deletions(-) > > -- > 2.27.0 -- - Arnaldo
