From 9fd74f209c69c9157584af9cdc500af9bbc06b82 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Tue, 5 Jan 2021 11:57:51 -0800 Subject: perf report: Add support for PERF_SAMPLE_CODE_PAGE_SIZE Add a new sort dimension "code_page_size" for common sort. With this option applied, perf can sort and report by sample's code page size. For example: # perf report --stdio --sort=comm,symbol,code_page_size # To display the perf.data header info, please use # --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 3K of event 'mem-loads:uP' # Event count (approx.): 1470769 # # Overhead Command Symbol Code Page Size IPC [IPC Coverage] # ........ ....... ............................ .............. .................... # 69.56% dtlb [.] GetTickCount 4K - - 17.93% dtlb [.] Calibrate 4K - - 11.40% dtlb [.] __gettimeofday 4K - - # Signed-off-by: Stephane Eranian Acked-by: Jiri Olsa Acked-by: Namhyung Kim Cc: Andi Kleen Cc: Ingo Molnar Cc: Mark Rutland Cc: Michael Ellerman Cc: Will Deacon Link: https://lore.kernel.org/r/20210105195752.43489-6-kan.liang@linux.intel.com Signed-off-by: Kan Liang Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/hist.h | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/perf/util/hist.h') diff --git a/tools/perf/util/hist.h b/tools/perf/util/hist.h index 14f66330923d..361108533a56 100644 --- a/tools/perf/util/hist.h +++ b/tools/perf/util/hist.h @@ -53,6 +53,7 @@ enum hist_column { HISTC_DSO_TO, HISTC_LOCAL_WEIGHT, HISTC_GLOBAL_WEIGHT, + HISTC_CODE_PAGE_SIZE, HISTC_MEM_DADDR_SYMBOL, HISTC_MEM_DADDR_DSO, HISTC_MEM_PHYS_DADDR, -- cgit v1.2.3
