From 0c5268bf2218144469dde3228f14898fadbbcdcd Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 4 Feb 2013 13:32:55 +0100 Subject: perf hists browser: Add support to display whole group data for raw columns Currently we don't display group members' values for raw columns like 'Samples' and 'Period' when in group report mode. Uniting '__hpp__percent_fmt' and '__hpp__raw_fmt' function under new function __hpp__fmt. It's basically '__hpp__percent_fmt' code with new 'fmt_percent' bool parameter added saying whether raw number or percentage should be printed. This way raw columns print out all the group members when in group report mode, like: $ perf record -e '{cycles,cache-misses}' ls ... $ perf report --group --show-total-period --stdio ... # Overhead Period Command Shared Object Symbol # ................ ........................ ....... ................. ................................. # 23.63% 11.24% 3331335 317 ls [kernel.kallsyms] [k] __lock_acquire 12.72% 0.00% 1793100 0 ls [kernel.kallsyms] [k] native_sched_clock 9.72% 0.00% 1369920 0 ls libc-2.14.90.so [.] _nl_find_locale 0.03% 0.07% 4476 2 ls [kernel.kallsyms] [k] intel_pmu_enable_all 0.00% 11.73% 0 331 ls ld-2.14.90.so [.] _dl_cache_libcmp 0.00% 11.06% 0 312 ls [kernel.kallsyms] [k] vma_interval_tree_insert Signed-off-by: Jiri Olsa Acked-by: Namhyung Kim Cc: Corey Ashford Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1359981185-16819-2-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/ui/hist.c | 53 ++++++++++++++++++++++++++-------------------------- 1 file changed, 26 insertions(+), 27 deletions(-) (limited to 'tools/perf') diff --git a/tools/perf/ui/hist.c b/tools/perf/ui/hist.c index a47ce98c2cb..d671e63aa35 100644 --- a/tools/perf/ui/hist.c +++ b/tools/perf/ui/hist.c @@ -9,18 +9,24 @@ typedef int (*hpp_snprint_fn)(char *buf, size_t size, const char *fmt, ...); -static int __hpp__percent_fmt(struct perf_hpp *hpp, struct hist_entry *he, - u64 (*get_field)(struct hist_entry *), - const char *fmt, hpp_snprint_fn print_fn) +static int __hpp__fmt(struct perf_hpp *hpp, struct hist_entry *he, + u64 (*get_field)(struct hist_entry *), + const char *fmt, hpp_snprint_fn print_fn, + bool fmt_percent) { int ret; - double percent = 0.0; struct hists *hists = he->hists; - if (hists->stats.total_period) - percent = 100.0 * get_field(he) / hists->stats.total_period; + if (fmt_percent) { + double percent = 0.0; + + if (hists->stats.total_period) + percent = 100.0 * get_field(he) / + hists->stats.total_period; - ret = print_fn(hpp->buf, hpp->size, fmt, percent); + ret = print_fn(hpp->buf, hpp->size, fmt, percent); + } else + ret = print_fn(hpp->buf, hpp->size, fmt, get_field(he)); if (symbol_conf.event_group) { int prev_idx, idx_delta; @@ -49,11 +55,15 @@ static int __hpp__percent_fmt(struct perf_hpp *hpp, struct hist_entry *he, * have no sample */ ret += print_fn(hpp->buf + ret, hpp->size - ret, - fmt, 0.0); + fmt, 0); } - ret += print_fn(hpp->buf + ret, hpp->size - ret, - fmt, 100.0 * period / total); + if (fmt_percent) + ret += print_fn(hpp->buf + ret, hpp->size - ret, + fmt, 100.0 * period / total); + else + ret += print_fn(hpp->buf + ret, hpp->size - ret, + fmt, period); prev_idx = perf_evsel__group_idx(evsel); } @@ -65,23 +75,12 @@ static int __hpp__percent_fmt(struct perf_hpp *hpp, struct hist_entry *he, * zero-fill group members at last which have no sample */ ret += print_fn(hpp->buf + ret, hpp->size - ret, - fmt, 0.0); + fmt, 0); } } return ret; } -static int __hpp__raw_fmt(struct perf_hpp *hpp, struct hist_entry *he, - u64 (*get_field)(struct hist_entry *), - const char *fmt, hpp_snprint_fn print_fn) -{ - int ret; - - ret = print_fn(hpp->buf, hpp->size, fmt, get_field(he)); - return ret; -} - - #define __HPP_HEADER_FN(_type, _str, _min_width, _unit_width) \ static int hpp__header_##_type(struct perf_hpp *hpp) \ { \ @@ -116,16 +115,16 @@ static u64 he_get_##_field(struct hist_entry *he) \ \ static int hpp__color_##_type(struct perf_hpp *hpp, struct hist_entry *he) \ { \ - return __hpp__percent_fmt(hpp, he, he_get_##_field, " %6.2f%%", \ - (hpp_snprint_fn)percent_color_snprintf); \ + return __hpp__fmt(hpp, he, he_get_##_field, " %6.2f%%", \ + (hpp_snprint_fn)percent_color_snprintf, true); \ } #define __HPP_ENTRY_PERCENT_FN(_type, _field) \ static int hpp__entry_##_type(struct perf_hpp *hpp, struct hist_entry *he) \ { \ const char *fmt = symbol_conf.field_sep ?
