It's unnecessary and heavy. To optimize it, create a single file "qos_pause_cfg" in tm directory and use cat command to get info. It will return info to userspace, rather than record in dmesg. The display style is below: $ cat qos_pause_cfg pause_trans_gap: 0x7f pause_trans_time: 0xffff Signed-off-by: Guangbin Huang Signed-off-by: Huazhong Tan --- drivers/net/ethernet/hisilicon/hns3/hnae3.h | 1 + drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c | 8 +++++- .../ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c | 30 ++++++++++++---------- 3 files changed, 25 insertions(+), 14 deletions(-) diff --git a/drivers/net/ethernet/hisilicon/hns3/hnae3.h b/drivers/net/ethernet/hisilicon/hns3/hnae3.h index dc6b8e3..dec3c77 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hnae3.h +++ b/drivers/net/ethernet/hisilicon/hns3/hnae3.h @@ -258,6 +258,7 @@ enum hnae3_dbg_cmd { HNAE3_DBG_CMD_TM_PG, HNAE3_DBG_CMD_TM_PORT, HNAE3_DBG_CMD_TC_SCH_INFO, + HNAE3_DBG_CMD_QOS_PAUSE_CFG, HNAE3_DBG_CMD_DEV_INFO, HNAE3_DBG_CMD_TX_BD, HNAE3_DBG_CMD_RX_BD, diff --git a/drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c b/drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c index 1719ff8..be2cde9c 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c +++ b/drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c @@ -93,6 +93,13 @@ static struct hns3_dbg_cmd_info hns3_dbg_cmd[] = { .init = hns3_dbg_common_file_init, }, { + .name = "qos_pause_cfg", + .cmd = HNAE3_DBG_CMD_QOS_PAUSE_CFG, + .dentry = HNS3_DBG_DENTRY_TM, + .buf_len = HNS3_DBG_READ_LEN, + .init = hns3_dbg_common_file_init, + }, + { .name = "dev_info", .cmd = HNAE3_DBG_CMD_DEV_INFO, .dentry = HNS3_DBG_DENTRY_COMMON, @@ -745,7 +752,6 @@ static void hns3_dbg_help(struct hnae3_handle *h) if (!hns3_is_phys_func(h->pdev)) return; - dev_info(&h->pdev->dev, "dump qos pause cfg\n"); dev_info(&h->pdev->dev, "dump qos pri map\n"); dev_info(&h->pdev->dev, "dump qos buf cfg\n"); dev_info(&h->pdev->dev, "dump mac tnl status\n"); diff --git a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c index bd62103..f7864f8 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c +++ b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c @@ -1028,27 +1028,29 @@ static int hclge_dbg_dump_tm_qset(struct hclge_dev *hdev, char *buf, int len) return 0; } -static void hclge_dbg_dump_qos_pause_cfg(struct hclge_dev *hdev) +static int hclge_dbg_dump_qos_pause_cfg(struct hclge_dev *hdev, char *buf, + int len) { struct hclge_cfg_pause_param_cmd *pause_param; struct hclge_desc desc; + int pos = 0; int ret; hclge_cmd_setup_basic_desc(&desc, HCLGE_OPC_CFG_MAC_PARA, true); - ret = hclge_cmd_send(&hdev->hw, &desc, 1); if (ret) { - dev_err(&hdev->pdev->dev, "dump checksum fail, ret = %d\n", - ret); - return; + dev_err(&hdev->pdev->dev, + "failed to dump qos pause, ret = %d\n", ret); + return ret; } pause_param = (struct hclge_cfg_pause_param_cmd *)desc.data; - dev_info(&hdev->pdev->dev, "dump qos pause cfg\n"); - dev_info(&hdev->pdev->dev, "pause_trans_gap: 0x%x\n", - pause_param->pause_trans_gap); - dev_info(&hdev->pdev->dev, "pause_trans_time: 0x%x\n", - le16_to_cpu(pause_param->pause_trans_time)); + + pos += scnprintf(buf + pos, len - pos, "pause_trans_gap: 0x%x\n", + pause_param->pause_trans_gap); + pos += scnprintf(buf + pos, len - pos, "pause_trans_time: 0x%x\n", + le16_to_cpu(pause_param->pause_trans_time)); + return 0; } static void hclge_dbg_dump_qos_pri_map(struct hclge_dev *hdev) @@ -1894,9 +1896,7 @@ int hclge_dbg_run_cmd(struct hnae3_handle *handle, const char *cmd_buf) struct hclge_vport *vport = hclge_get_vport(handle); struct hclge_dev *hdev = vport->back; - if (strncmp(cmd_buf, "dump qos pause cfg", 18) == 0) { - hclge_dbg_dump_qos_pause_cfg(hdev); - } else if (strncmp(cmd_buf, "dump qos pri map", 16) == 0) { + if (strncmp(cmd_buf, "dump qos pri map", 16) == 0) { hclge_dbg_dump_qos_pri_map(hdev); } else if (strncmp(cmd_buf, "dump qos buf cfg", 16) == 0) { hclge_dbg_dump_qos_buf_cfg(hdev); @@ -1945,6 +1945,10 @@ static const struct hclge_dbg_func hclge_dbg_cmd_func[] = { .dbg_dump = hclge_dbg_dump_tc, }, { + .cmd = HNAE3_DBG_CMD_QOS_PAUSE_CFG, + .dbg_dump = hclge_dbg_dump_qos_pause_cfg, + }, + { .cmd = HNAE3_DBG_CMD_MAC_UC, .dbg_dump = hclge_dbg_dump_mac_uc, },
