From 9f8666971185b86615a074bcac67c90fdf8af8bc Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Mon, 10 Aug 2009 15:26:32 +0200 Subject: perf report: Add raw displaying of per-thread counters If --pretty=raw is given to perf report -T, it now displays one line per-thread per-counter with the raw event id added. We get: # PID TID Name Raw Count 18608 18609 cache-misses 28e 416744 18608 18609 cache-references 28f 6456792 18608 18608 cache-misses 28e 448219 18608 18608 cache-references 28f 7270244 instead of: # PID TID cache-misses cache-references 18608 18609 416744 6456792 18608 18608 448219 7270244 Signed-off-by: Brice Goglin Acked-by: Peter Zijlstra LKML-Reference: <4A802008.5050409@inria.fr> Signed-off-by: Ingo Molnar --- tools/perf/util/values.c | 62 +++++++++++++++++++++++++++++++++++++++++++++++- tools/perf/util/values.h | 3 ++- 2 files changed, 63 insertions(+), 2 deletions(-) (limited to 'tools/perf/util') diff --git a/tools/perf/util/values.c b/tools/perf/util/values.c index 8551c0b8b23..614cfaf4712 100644 --- a/tools/perf/util/values.c +++ b/tools/perf/util/values.c @@ -126,7 +126,8 @@ void perf_read_values_add_value(struct perf_read_values *values, values->value[tindex][cindex] = value; } -void perf_read_values_display(FILE *fp, struct perf_read_values *values) +static void perf_read_values__display_pretty(FILE *fp, + struct perf_read_values *values) { int i, j; int pidwidth, tidwidth; @@ -169,3 +170,62 @@ void perf_read_values_display(FILE *fp, struct perf_read_values *values) fprintf(fp, "\n"); } } + +static void perf_read_values__display_raw(FILE *fp, + struct perf_read_values *values) +{ + int width, pidwidth, tidwidth, namewidth, rawwidth, countwidth; + int i, j; + + tidwidth = 3; /* TID */ + pidwidth = 3; /* PID */ + namewidth = 4; /* "Name" */ + rawwidth = 3; /* "Raw" */ + countwidth = 5; /* "Count" */ + + for (i = 0; i < values->threads; i++) { + width = snprintf(NULL, 0, "%d", values->pid[i]); + if (width > pidwidth) + pidwidth = width; + width = snprintf(NULL, 0, "%d", values->tid[i]); + if (width > tidwidth) + tidwidth = width; + } + for (j = 0; j < values->counters; j++) { + width = strlen(values->countername[j]); + if (width > namewidth) + namewidth = width; + width = snprintf(NULL, 0, "%llx", values->counterrawid[j]); + if (width > rawwidth) + rawwidth = width; + } + for (i = 0; i < values->threads; i++) { + for (j = 0; j < values->counters; j++) { + width = snprintf(NULL, 0, "%Lu", values->value[i][j]); + if (width > countwidth) + countwidth = width; + } + } + + fprintf(fp, "# %*s %*s %*s %*s %*s\n", + pidwidth, "PID", tidwidth, "TID", + namewidth, "Name", rawwidth, "Raw", + countwidth, "Count"); + for (i = 0; i < values->threads; i++) + for (j = 0; j < values->counters; j++) + fprintf(fp, " %*d %*d %*s %*llx %*Lu\n", + pidwidth, values->pid[i], + tidwidth, values->tid[i], + namewidth, values->countername[j], + rawwidth, values->counterrawid[j], + countwidth, values->value[i][j]); +} + +void perf_read_values_display(FILE *fp, struct perf_read_values *values, + int raw) +{ + if (raw) + perf_read_values__display_raw(fp, values); + else + perf_read_values__display_pretty(fp, values); +} diff --git a/tools/perf/util/values.h b/tools/perf/util/values.h index e41be5e86e6..f8960fde054 100644 --- a/tools/perf/util/values.h +++ b/tools/perf/util/values.h @@ -21,6 +21,7 @@ void perf_read_values_add_value(struct perf_read_values *values, u32 pid, u32 tid, u64 rawid, char *name, u64 value); -void perf_read_values_display(FILE *fp, struct perf_read_values *values); +void perf_read_values_display(FILE *fp, struct perf_read_values *values, + int raw); #endif /* _PERF_VALUES_H */ -- cgit v1.2.3
