Actually printing once is acceptable but sometimes it will print again and again, it looks very annoying. It is better to change these detail messages to debugging only. cfg80211: World regulatory domain updated: cfg80211: DFS Master region: unset cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (N/A, 2000 mBm), (N/A) cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (N/A) cfg80211: (5250000 KHz - 5330000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (0 s) cfg80211: (5490000 KHz - 5730000 KHz @ 160000 KHz), (N/A, 2000 mBm), (0 s) cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) cfg80211: (57240000 KHz - 63720000 KHz @ 2160000 KHz), (N/A, 0 mBm), (N/A) The changes in this patch is to replace pr_info with pr_debug in function print_rd_rules and print_regdomain_info Signed-off-by: Dave Young --- net/wireless/reg.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) --- linux.orig/net/wireless/reg.c +++ linux/net/wireless/reg.c @@ -2763,7 +2763,7 @@ static void print_rd_rules(const struct const struct ieee80211_power_rule *power_rule = NULL; char bw[32], cac_time[32]; - pr_info(" (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time)\n"); + pr_debug(" (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time)\n"); for (i = 0; i < rd->n_reg_rules; i++) { reg_rule = &rd->reg_rules[i]; @@ -2790,7 +2790,7 @@ static void print_rd_rules(const struct * in certain regions */ if (power_rule->max_antenna_gain) - pr_info(" (%d KHz - %d KHz @ %s), (%d mBi, %d mBm), (%s)\n", + pr_debug(" (%d KHz - %d KHz @ %s), (%d mBi, %d mBm), (%s)\n", freq_range->start_freq_khz, freq_range->end_freq_khz, bw, @@ -2798,7 +2798,7 @@ static void print_rd_rules(const struct power_rule->max_eirp, cac_time); else - pr_info(" (%d KHz - %d KHz @ %s), (N/A, %d mBm), (%s)\n", + pr_debug(" (%d KHz - %d KHz @ %s), (N/A, %d mBm), (%s)\n", freq_range->start_freq_khz, freq_range->end_freq_khz, bw, @@ -2831,35 +2831,35 @@ static void print_regdomain(const struct struct cfg80211_registered_device *rdev; rdev = cfg80211_rdev_by_wiphy_idx(lr->wiphy_idx); if (rdev) { - pr_info("Current regulatory domain updated by AP to: %c%c\n", + pr_debug("Current regulatory domain updated by AP to: %c%c\n", rdev->country_ie_alpha2[0], rdev->country_ie_alpha2[1]); } else - pr_info("Current regulatory domain intersected:\n"); + pr_debug("Current regulatory domain intersected:\n"); } else - pr_info("Current regulatory domain intersected:\n"); + pr_debug("Current regulatory domain intersected:\n"); } else if (is_world_regdom(rd->alpha2)) { - pr_info("World regulatory domain updated:\n"); + pr_debug("World regulatory domain updated:\n"); } else { if (is_unknown_alpha2(rd->alpha2)) - pr_info("Regulatory domain changed to driver built-in settings (unknown country)\n"); + pr_debug("Regulatory domain changed to driver built-in settings (unknown country)\n"); else { if (reg_request_cell_base(lr)) - pr_info("Regulatory domain changed to country: %c%c by Cell Station\n", + pr_debug("Regulatory domain changed to country: %c%c by Cell Station\n", rd->alpha2[0], rd->alpha2[1]); else - pr_info("Regulatory domain changed to country: %c%c\n", + pr_debug("Regulatory domain changed to country: %c%c\n", rd->alpha2[0], rd->alpha2[1]); } } - pr_info(" DFS Master region: %s", reg_dfs_region_str(rd->dfs_region)); + pr_debug(" DFS Master region: %s", reg_dfs_region_str(rd->dfs_region)); print_rd_rules(rd); } static void print_regdomain_info(const struct ieee80211_regdomain *rd) { - pr_info("Regulatory domain: %c%c\n", rd->alpha2[0], rd->alpha2[1]); + pr_debug("Regulatory domain: %c%c\n", rd->alpha2[0], rd->alpha2[1]); print_rd_rules(rd); } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
