The 1GHz is 1000,000,000. So it needs the least 10 position to show the GHz unit. - Before apply this patch, -sh-3.2# cat trans_stat From : To :50000000100000000133000000200000000400000000 time(ms) *50000000: 0 0 0 0 7 1817635 100000000: 4 0 0 0 4 1590 133000000: 1 4 0 0 7 975 200000000: 2 2 7 0 1 2655 400000000: 0 2 5 12 0 1860 Total transition : 58 - After apply this patch, -sh-3.2# cat trans_stat From : To : 50000000 100000000 133000000 200000000 400000000 time(ms) * 50000000: 0 0 0 0 7 14405 100000000: 4 0 0 0 3 2015 133000000: 2 3 0 0 7 1020 200000000: 1 2 7 0 0 2970 400000000: 0 2 5 10 0 1575 Total transition : 53 Signed-off-by: Chanwoo Choi --- drivers/devfreq/devfreq.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/devfreq/devfreq.c b/drivers/devfreq/devfreq.c index 761e46a95c4b..c292ceb7ff19 100644 --- a/drivers/devfreq/devfreq.c +++ b/drivers/devfreq/devfreq.c @@ -1048,10 +1048,10 @@ static ssize_t trans_stat_show(struct device *dev, devfreq_update_status(devfreq, devfreq->previous_freq)) return 0; - len = sprintf(buf, " From : To\n"); - len += sprintf(buf + len, " :"); + len = sprintf(buf, " From : To\n"); + len += sprintf(buf + len, " :"); for (i = 0; i < max_state; i++) - len += sprintf(buf + len, "%8ld", + len += sprintf(buf + len, "%10ld", devfreq->profile->freq_table[i]); len += sprintf(buf + len, " time(ms)\n"); @@ -1063,10 +1063,10 @@ static ssize_t trans_stat_show(struct device *dev, } else { len += sprintf(buf + len, " "); } - len += sprintf(buf + len, "%8ld:", + len += sprintf(buf + len, "%10ld:", devfreq->profile->freq_table[i]); for (j = 0; j < max_state; j++) - len += sprintf(buf + len, "%8u", + len += sprintf(buf + len, "%10u", devfreq->trans_table[(i * max_state) + j]); len += sprintf(buf + len, "%10u\n", jiffies_to_msecs(devfreq->time_in_state[i])); -- 1.9.1
