Add new macros for mem_hops field which can be used to represent remote-node, socket and board level details. Currently the code had macro for HOPS_0 which, corresponds to data coming from another core but same node. Add new macros for HOPS_1 to HOPS_3 to represent remote-node, socket and board level data. Also add corresponding strings in the mem_hops array to represent mem_hop field data in perf_mem__lvl_scnprintf function Incase mem_hops field is used, PERF_MEM_LVLNUM field also need to be set inorder to represent the data source. Hence printing data source via PERF_MEM_LVL field can be skip in that scenario. For ex: Encodings for mem_hops fields with L2 cache: 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 Signed-off-by: Kajol Jain <kjain@linux.ibm.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Madhavan Srinivasan <maddy@linux.ibm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Nageswara R Sastry <rnsastry@linux.ibm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Song Liu <songliubraving@fb.com> Cc: linuxppc-dev@lists.ozlabs.org Link: http://lore.kernel.org/lkml/20211206091749.87585-3-kjain@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
