[v4,2/7] ethdev: add telemetry cmd for registers
Checks
Commit Message
This patch adds a telemetry command for registers dump,
and supports get registers with specified names.
The length of the string exported by telemetry is limited
by MAX_OUTPUT_LEN. Therefore, the filter should be more
precise.
An example usage is shown below:
--> /ethdev/regs,0,INTR
{
"/ethdev/regs": {
"registers_length": 318,
"registers_width": 4,
"register_offset": "0x0",
"version": "0x1140011",
"group_0": {
"HNS3_CMDQ_INTR_STS_REG": "0x0",
"HNS3_CMDQ_INTR_EN_REG": "0x2",
"HNS3_CMDQ_INTR_GEN_REG": "0x0",
"queue_0_HNS3_TQP_INTR_CTRL_REG": "0x0",
"queue_0_HNS3_TQP_INTR_GL0_REG": "0xa",
"queue_0_HNS3_TQP_INTR_GL1_REG": "0xa",
"queue_0_HNS3_TQP_INTR_GL2_REG": "0x0",
...
},
"group_1": {
...
},
...
}
or as below if the number of registers not exceed the
RTE_TEL_MAX_DICT_ENTRIES:
--> /ethdev/regs,0,ppp
{
"/ethdev/regs": {
"registers_length": 156,
"registers_width": 4,
"register_offset": "0x0",
"version": "0x1140011",
"ppp_key_drop_num": "0x0",
"ppp_rlt_drop_num": "0x0",
"ssu_ppp_mac_key_num_l": "0x1",
"ssu_ppp_mac_key_num_h": "0x0",
"ssu_ppp_host_key_num_l": "0x1",
"ssu_ppp_host_key_num_h": "0x0",
"ppp_ssu_mac_rlt_num_l": "0x1",
...
}
}

The above format is OK for reg_info->width==4.
There maybe reg_info->width == 8, pls support it.

grp_num + 1 ?

how about add more descrip: stop format!

this group's memory was leak.
How about move the extream case before for loop:
uint32_t length = reg_info->lenght;
if (length > RTE_TEL_MAX_DICT_ENTRIES * RTE_TEL_MAX_DICT_ENTRIES) {
LOG(xxx);
length = RTE_TEL_MAX_DICT_ENTRIES * RTE_TEL_MAX_DICT_ENTRIES;
}

how about move all add dict in here.
for (i = 0; i < grp_num; i++) {
snprintf(group_name, xxx);
rte_tel_data_add_dict_container(d, group_name, group[i], 0);
