2021-11-24net: hns3: debugfs add drop packet statistics of multicast and broadcast for iguJie Wang1-4/+4
Currently, there is no way to get drop packet number of multicast and broadcast in IGU hardware module, it is not convenient to find problem when multicast packet or broadcast packet is dropped in IGU, so this patch adds statistics for them in debugfs.

Add debugfs support for vlan configuraion. create a single file "vlan_config" for it, and query it by command "cat vlan_config", return the result to userspace. The new display style is below: $ cat vlan_config I_PORT_VLAN_FILTER: on E_PORT_VLAN_FILTER: off FUNC_ID I_VF_VLAN_FILTER E_VF_VLAN_FILTER PORT_VLAN_FILTER_BYPASS pf off on off vf0 off on off FUNC_ID PVID ACCEPT_TAG1 ACCEPT_TAG2 ACCEPT_UNTAG1 ACCEPT_UNTAG2 pf 0 on on on on vf0 0 on on on on Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Currently, the debugfs command for serv info is implemented by "echo xxxx > cmd", and record the inforamtion in dmesg. It's unnecessary and heavy. To improve it, create a single file "serv_info" for it, and query it by command "cat serv_info", return the result to userspace, rather than record in dmesg.

2021-05-20net: hns3: refactor dump tm of debugfsGuangbin Huang1-0/+2
Currently, user gets some tm info by implementing debugfs command "echo dump tm > cmd", this command will dump info in dmesg. It's unnecessary and heavy. In addition, the info of this command mixes info of qset, priority, pg and port. Qset and priority have their own command to get info of themself, so can remove info of qset and priority from this command. To optimize it, create two new files "tm_pg", "tm_port" in tm directory and use cat command to separately get info of pg and port. The display style is below: $ cat tm_pg ID PRI_MAP MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S ... 00 0x1f dwrr 1 75 9 0 31 20 ... $ cat tm_port IR_B IR_U IR_S BS_B BS_S FLAG RATE(Mbps) 75 9 0 31 20 1 200000 Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2020-12-06net: hns3: remove a misused pragma packedHuazhong Tan1-4/+0
hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings. Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry.

2020-09-23net: hns3: Constify static structsRikard Falkeborn1-13/+13
A number of static variables were not modified. Make them const to allow the compiler to put them in read-only memory. In order to do so, constify a couple of input pointers as well as some local pointers. This moves about 35Kb to read-only memory as seen by the output of the size command.

2019-08-29net: hns3: code optimization for debugfs related to "dump reg"Zhongzhu Liu1-0/+16
For making the code more readable, this patch uses a array to keep the information about the dumping register, and then uses it to parse the parameter cmd_buf which passing into hclge_dbg_dump_reg_cmd(). Also replaces parameter "base" of kstrtouint with 0 in the hclge_dbg_dump_reg_common(), which makes it more flexible.
