From 2c9db7475e5de5125b5043fe8f560284b248b0ae Mon Sep 17 00:00:00 2001 From: Athira Rajeev Date: Thu, 18 Jul 2024 14:13:58 +0530 Subject: perf annotate: Set instruction name to be used with insn-stat when using raw instruction Since the "ins.name" is not set while using raw instruction, 'perf annotate' with insn-stat gives wrong data: Result from "./perf annotate --data-type --insn-stat": Annotate Instruction stats total 615, ok 419 (68.1%), bad 196 (31.9%) Name : Good Bad ----------------------------------------------------------- : 419 196 This patch sets "dl->ins.name" in arch specific function "check_ppc_insn" while initialising "struct disasm_line". Also update "ins_find" function to pass "struct disasm_line" as a parameter so as to set its name field in arch specific call. With the patch changes: Annotate Instruction stats total 609, ok 446 (73.2%), bad 163 (26.8%) Name/opcode : Good Bad ----------------------------------------------------------- 58 : 323 80 32 : 49 43 34 : 33 11 OP_31_XOP_LDX : 8 20 40 : 23 0 OP_31_XOP_LWARX : 5 1 OP_31_XOP_LWZX : 2 3 OP_31_XOP_LDARX : 3 0 33 : 0 2 OP_31_XOP_LBZX : 0 1 OP_31_XOP_LWAX : 0 1 OP_31_XOP_LHZX : 0 1 Reviewed-by: Kajol Jain Reviewed-by: Namhyung Kim Signed-off-by: Athira Rajeev Tested-by: Kajol Jain Cc: Adrian Hunter Cc: Akanksha J N Cc: Christophe Leroy Cc: Disha Goel Cc: Hari Bathini Cc: Ian Rogers Cc: Jiri Olsa Cc: Madhavan Srinivasan Cc: Segher Boessenkool Link: https://lore.kernel.org/lkml/20240718084358.72242-16-atrajeev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/builtin-annotate.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'tools/perf/builtin-annotate.c') diff --git a/tools/perf/builtin-annotate.c b/tools/perf/builtin-annotate.c index b10b7f005658..cf60392b1c19 100644 --- a/tools/perf/builtin-annotate.c +++ b/tools/perf/builtin-annotate.c @@ -396,10 +396,10 @@ static void print_annotate_item_stat(struct list_head *head, const char *title) printf("total %d, ok %d (%.1f%%), bad %d (%.1f%%)\n\n", total, total_good, 100.0 * total_good / (total ?: 1), total_bad, 100.0 * total_bad / (total ?: 1)); - printf(" %-10s: %5s %5s\n", "Name", "Good", "Bad"); + printf(" %-20s: %5s %5s\n", "Name/opcode", "Good", "Bad"); printf("-----------------------------------------------------------\n"); list_for_each_entry(istat, head, list) - printf(" %-10s: %5d %5d\n", istat->name, istat->good, istat->bad); + printf(" %-20s: %5d %5d\n", istat->name, istat->good, istat->bad); printf("\n"); } -- cgit v1.2.3
