The ethdev library now registers a telemetry command for
dump regs.
An example usage is shown below:
--> /ethdev/regs,test
{
"/ethdev/regs": {
"regs_offset": 0,
"regs_length": 3192,
"regs_width": 4,
"device_version": "0x1080f00",
"regs_file": "port_0_regs_test"
}
}

Above code writes register data to a file.
I am not sure about this kind of usage of telemetry command, that it
cause data to be written to a file.
My understanding is, telemetry usage is based on what telemetry client
receives.
What do you think just keep the 'reg_info' fields excluding data to the
file?

I tried to write all register information to telemetry data,
but gave up because some drivers had too many registers (eg.ixgbe)
to carry. Therefore, the writing data to file approach is selected.
When we query a register, the register content is the key.
The information such as the width and length is only auxiliary
information. If the register data cannot be obtained, the auxiliary
information is optional. So I don't think register data should be removed.
In my opinion, writing a file is a more appropriate way to do it.
I wonder if there's a better way.
Best regards,
Thanks

Sorry, correct it. It is i40e who has the most registers.

Is there a usecase to get register information from telemetry interface?

Among the available tools:
1, ethtool/proc-info: should use multi-process mechanism to connect to the main process
2, telemetry: easier, lighter load, and it don't need re-probe the ethdev in the secondary process,
and also cost more resource, like hugepage, cores.
From our users, they prefer use the second 'telemetry', so I think we should move
more status-query-points to telemetry.
As for this question, I think it's okay to get register info from telemetry.
Another question, we have some internal registers, which:
1. Is not suitable expose by xstats, because they may includes configuration
2. Is not suitable expose by dumps, because this dumps is hard to understand (because it only has value).
So we plan to add some telemetry points in the driver itself, so we could display them like xstats:
"xxxx" : 0x1234
"yyyy" : 0x100
Will the community accept this kind of telemetry points which limit one driver ?
Thanks.

Hi Chengwen,
I see there is a usecase/requirement.
With this patch, even using file, only register values are dumped and
isn't it hard to find value of specific register?
("xxxx" : 0x1234) approach looks better, but instead of making this
telemetry support for specific driver, what about making it in two steps.
First add new dev_ops, (or update existing one), to get registers with
"name: value" format, (in a way to allow empty name), or even perhaps
"name: offset, value" format.
And in second stage add telemetry support around it.
(Name being optional lets us wrap exiting 'get_reg' dev_ops with new one)
When adding dev_ops, it may get an additional 'filter' parameter, to get
only subset of regs, like "mac*" to get regs name staring with "mac",
this may help for the cases there are too many registers you mentioned.
Anyway, we can discuss more about its design, but what do you think
about first having a dev_ops for this?

I'm OK to add an API for dumping registers, and guess what?
We already have it: rte_eth_dev_get_reg_info().
We may extend it to query a subset of registers.

This patch already using 'rte_eth_dev_get_reg_info()', but issue is how
it is used, it gets filename from telemetry and dumps registers to that
file.

Reading some registers can be debugging or monitoring, I believe it is
in the gray area.

I prefer extend struct rte_dev_reg_info, like this:
struct rte_eth_reg_name {
char name[RTE_ETH_REG_NAME_SIZE];
};
struct rte_dev_reg_info {
void *data; /**< Buffer for return registers */
uint32_t offset; /**< Start register table location for access */
uint32_t length; /**< Number of registers to fetch */
uint32_t width; /**< Size of device register */
uint32_t version; /**< Device version */
/* Note: below two fields are new added. */
char *filter; /**< Filter for target subset of registers. This field could affects register selection for data/length/name. */
struct rte_eth_reg_name *names; /**< Registers name saver. */
};
For driver which don't identify the new filter and names fields:
1. .get_reg return the all registers value.
2. and driver will not touch the name fields.
3. rte_eth_dev_get_reg_info() could detect name fileds not filled, and then it fill with default names, e.g. offset-1/offset-2/...
For driver which identify the new filter and names fields:
1. rte_eth_dev_get_reg_info() will return filtered register's value and also their names.
So that those which invoke rte_eth_dev_get_reg_info() could extra prepare names, and it call the same API will get data and name.
Add one new .get_reg_name ops and corresponding API like: rte_eth_dev_get_reg_name() could also feasible.
But I think the rte_eth_dev_get_reg_info()'s name is too broad, the info could includes value and also it's name.
So I prefer not add one new ops.
Another question? what are the supported values of filters ?
I prefer report by dev_info ops, something like a string array end with NULL.
Use could query from rte_eth_dev_info_get API.
Thanks.

Is there a benefit to provide default names? API can clear the 'names'
buffer, and driver may or may not fill it. If names not filled, API
behaves like existing one, it will just provide register values.

I don't think there is a need to populate predefined filter list, it can
be free text with simple '*' and '.' wildcard support and ',' to support
list of text.
User may get full list first, later can filter the ones they are interested.
Like: "*mac*,*rss*" can match all register names that has 'mac' and
'rss' in it.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient
for users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext
is added to support the capability of exporting the name of the
corresponding register and filtering by names.
The hns3 driver and telemetry are examples for that.
--
v2:
1. fix compile error.
2. add new API to support it instead of the old one.
3. split patches on hns3 driver.

ethdev: support report register names and filter
ethdev: add telemetry cmd for registers
net/hns3: fix dump counter of registers
net/hns3: remove dump format of registers
net/hns3: add names for registers

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their names.
For compatibility, the original API rte_eth_dev_get_reg_info()
does not use the name and filter fields. The new API
rte_eth_dev_get_reg_info_ext() is added to support reporting
names and filtering by names. If the drivers does not report
the names, set them to "offset_XXX".

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",
...
}

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between diffent register modules.

To: dev; +Cc: lihuisong, fengchengwen, liuyonglong, huangdengdui, ferruh.yigit
This patch adds names for all registers to be dumped.
For those who can be directly accessed by their addresses,
a new structure containing both name and address is added
and the related arrays is refactored and renamed.
For the remaining modules, there may be different meanings
on different platforms for the same field. Therefore, two
name fields are provided.
There are some 64-bit registers, dump them as two 32-bit
registers.

This will break the ABI.
Think about a case, an application compiled with an old version of DPDK,
later same application started to use this version without re-compile,
application will send old version of 'struct rte_dev_reg_info', but new
version of DPDK will try to access or update new fields of the 'struct
rte_dev_reg_info'
One option is:
- to add a new 'struct rte_dev_reg_info_ext',
- 'rte_eth_dev_get_reg_info()' still uses old 'struct rte_dev_reg_info'
- 'get_reg()' dev_ops will use this new 'struct rte_dev_reg_info_ext'
- Add deprecation notice to update 'rte_eth_dev_get_reg_info()' to use
new struct in next LTS release

May be good to mention if info->names is not NULL, but driver doesn't
support names, ehtdev fills the names automatically.
As both 'rte_eth_dev_get_reg_info()' & 'rte_eth_dev_get_reg_info_ext()'
use same dev_ops ('get_reg()'), it is possible that driver doesn't
support filtering, so if the user provides info->filter but driver
doesn't support it, I think API should return error, what do you think?
And can you please make it clear above, if filtering is provided with
info->data = NULL, are the returned width and length fields for filtered
number of registers or all registers?

Can you please make the new API as experimental. That is the requirement
for new APIs.
Also need to add the API to version.map

Actually, we use a local variable "struct rte_dev_reg_info reg_info" in
'rte_eth_dev_get_reg_info()' to pass to the driver, and the new fields
are set to zero. The old drivers do not visit the new fields.
We make constrains that if filter is NULL, do not filter and get info of
all registers.
For an old version APP and new version ethdev, driver will not visit the
new fields. so it does not break the ABI.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient
for users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext
is added to support the capability of exporting the name of the
corresponding register and filtering by names.
The hns3 driver and telemetry are examples for that.
--
v3:
1. fix mispellings.
2. use snprintf instead of sprintf.
3. add more comment on rte_eth_dev_get_reg_info_ext.
4. add __rte_experimental.
5. add version map.
v2:
1. fix compile error.
2. add new API to support it instead of the old one.
3. split patches on hns3 driver.

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by names. And the original API
rte_eth_dev_get_reg_info() does not use the name and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "offset_XXX".

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",
...
}

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between different register modules.

This patch adds names for all registers to be dumped.
For those who can be directly accessed by their addresses,
a new structure containing both name and address is added
and the related arrays is refactored and renamed.
For the remaining modules, there may be different meanings
on different platforms for the same field. Therefore, two
name fields are provided.
There are some 64-bit registers, dump them as two 32-bit
registers.

filter and names should be const, i.e won't get modified by call.

Those NULL assignments are unnecessary, already initialized structure.

For a dict in telemetry, the total num of elements is
RTE_TEL_MAX_DICT_ENTRIES which is 256.
The number of registers may be greater than that.
One option is to seperate the registers in different groups,
each group can be stored in a dict A and can be an entry of another dict B.
RTE_TEL_MAX_DICT_ENTRIES is used so that B has as less as possible
elements and to make full use of the memory allocated.

Hi, Stephen,
Thanks for your review.
The app proc-info and ethtool already support dump registers with
the rte_eth_dev_get_reg_info API. For the use of the new API,
I think it's better to discuss whether to add or replace the
API of the two apps after the API of the new version is applied.
Best Regards,
Jie Hai

The "filter" can be a pointer to a const string. It's OK to add const.
The "names" could be modified. The APPs are free to assign space for
regisger names and "names" point to the first element.
And the ethdev and drivers are free to modifiy each element.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient
for users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext
is added to support the capability of exporting the name of the
corresponding register and filtering by names.
The hns3 driver and telemetry are examples for that.

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by names. And the original API
rte_eth_dev_get_reg_info() does not use the name and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "offset_XXX".

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",

"ppp_ssu_mac_rlt_num_l": "0x1",

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between different register modules.

This patch adds names for all registers to be dumped.
For those who can be directly accessed by their addresses,
a new structure containing both name and address is added
and the related arrays is refactored and renamed.
For the remaining modules, there may be different meanings
on different platforms for the same field. Therefore, two
name fields are provided.
There are some 64-bit registers, dump them as two 32-bit
registers.

%x has no prefix "0x", may lead to confused.
How about use %u ?
Another question, if app don't zero names' memory, then its value is random, so it will not enter this logic.
Suggest memset item[0]'s name memory before invoke PMD ops.

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

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.

snprintf(group_name, xxx);

Isn't it possible to implement filtering in the original function?
What would it break?

If we implement filtering in the original function
rte_eth_dev_get_reg_info(), ABI would be broken and
old app cannot run with linked to the new library.
Existing binary applications will have backwards compatibility with our
current patch.
Although the ABI is modified, the old app can still behave normally in
the case of dynamic linking with the new library.
And the new APP using rte_eth_dev_get_reg_info() works well with the
old library.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient
for users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext
is added to support the capability of exporting the name of the
corresponding register and filtering by names.
The hns3 driver and telemetry are examples for that.
--
v5:
1. fix version map.
2. fix comment on rte_eth_dev_get_reg_info_ext.
3. set RTE_ETH_REG_NAME_SIZE to 64.
4. fix default register name.
5. add support for reg_info->width == 8 in telemetry.
6. add memeory allocate fail log.
7. fix memory access for telemetry to store extra registers.
v4:
1. fix mispellings.
2. add const to 'filter'.
3. remove redundant assigning.
v3:
1. fix mispellings.
2. use snprintf instead of sprintf.
3. add more comment on rte_eth_dev_get_reg_info_ext.
4. add __rte_experimental.
5. add version map.
v2:
1. fix compile error.
2. add new API to support it instead of the old one.
3. split patches on hns3 driver.
Jie Hai (7):

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by names. And the original API
rte_eth_dev_get_reg_info() does not use the names and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "offset_XXX".

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",
...
}
}

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between different register modules.

To: dev, Yisen Zhuang; +Cc: lihuisong, fengchengwen, haijie1
This patch adds names for all registers to be dumped.
For those who can be directly accessed by their addresses,
a new structure containing both name and address is added
and the related arrays is refactored and renamed.
For the remaining modules, there may be different meanings
on different platforms for the same field. Therefore, two
name fields are provided.
There are some 64-bit registers, dump them as two 32-bit
registers.

Here adding u32_hex or u64_hex should depend on the reg_info->width, right?
Even though it is ok now due to the validity check in
eth_dev_add_u32_hex and eth_dev_add_u64_hex.
Using the validity check to control the code flow is ok.
But u32 and u64 interface are parallel.
It's obvious that one of them will be selected for execution here.
So suggest that modify it as following logic:
"
if (reg_info->width == sizeof(uint32_t))
eth_dev_add_u32_hex(d, reg_info->names[i].name, &data0)
else
eth_dev_add_u64_hex(d, reg_info->names[i].name, &data1);

If there are different names for these register,
how about use a common name like ppp_func_reg1、ppp_func_reg2?
or do not show the new register name on latter platform and only use the
original name, "ppp_rsv5/6".
Because we don't know if this register name will be changed on the new
plaform in furture.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient for
users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext is added
to support the capability of exporting the name of the corresponding
register and filtering by module names.
The hns3 driver and telemetry are examples for that.
Jie Hai (8):
ethdev: support report register names and filter
ethdev: add telemetry cmd for registers
net/hns3: remove some basic address dump
net/hns3: fix dump counter of registers
net/hns3: remove separators between register module
net/hns3: refactor register dump
net/hns3: support report names of registers
net/hns3: support filter registers by module names

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their module names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by modules. And the original API
rte_eth_dev_get_reg_info() does not use the names and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "index_XXX", which means the location in the register table.

This patch adds a telemetry command for registers dump,
and supports obtaining the registers of a specified module.
In one way, the number of registers that can be exported
is limited by the number of elements carried by dict and
container. In another way, the length of the string
exported by telemetry is limited by MAX_OUTPUT_LEN.
Therefore, when the number of registers to be exported
exceeds, some information will be lost. Warn on the former
case.
An example usage is shown below:
--> /ethdev/regs,0,ring
{
"/ethdev/regs": {
"registers_length": 318,
"registers_width": 4,
"register_offset": "0x0",
"version": "0x1140011",
"group_0": {
"Q0_ring_rx_bd_num": "0x0",
"Q0_ring_rx_bd_len": "0x0",
...
},
"group_1": {
...
},
...
}

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

all registers, remove the counter and insert of separators

To: dev, Yisen Zhuang; +Cc: lihuisong, fengchengwen, thomas, ferruh.yigit
This patch support dumping registers which name contains the
`filter` string. The module names are in lower case and so is
the `filter`. Available module names are cmdq, common_pf,
common_vf, ring, tqp_intr, 32_bit_dfx, 64_bit_dfx, bios, igu_egu,
ssu, ppp, rpu, ncsi, rtc, rcb, etc.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient for
users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext is added
to support the capability of exporting the name of the corresponding
register and filtering by module names.
The hns3 driver and telemetry are examples for that.
Jie Hai (8):
ethdev: support report register names and filter
ethdev: add telemetry cmd for registers
net/hns3: remove some basic address dump
net/hns3: fix dump counter of registers
net/hns3: remove separators between register module
net/hns3: refactor register dump
net/hns3: support report names of registers

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their module names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by modules. And the original API
rte_eth_dev_get_reg_info() does not use the names and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "index_XXX", which means the location in the register table.

This patch adds a telemetry command for registers dump,
and supports obtaining the registers of a specified module.
In one way, the number of registers that can be exported
is limited by the number of elements carried by dict and
container. In another way, the length of the string
exported by telemetry is limited by MAX_OUTPUT_LEN.
Therefore, when the number of registers to be exported
exceeds, some information will be lost. Warn on the former
case.
An example usage is shown below:
--> /ethdev/regs,0,ring
{
"/ethdev/regs": {
"registers_length": 318,
"registers_width": 4,
"register_offset": "0x0",
"version": "0x1140011",
"group_0": {
"Q0_ring_rx_bd_num": "0x0",
"Q0_ring_rx_bd_len": "0x0",
...
},
"group_1": {
...
},
...
}

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.
Fixes: acb3260fac5c ("net/hns3: fix dump register out of range")
Fixes: 936eda25e8da ("net/hns3: support dump register")

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between different register modules.

names of registers. Some registers has different names on
different platform, use names of HIP08 as default names.

This patch support dumping registers which name contains the
`filter` string. The module names are in lower case and so is
the `filter`. Available module names are cmdq, common_pf,
common_vf, ring, tqp_intr, 32_bit_dfx, 64_bit_dfx, bios, igu_egu,
ssu, ppp, rpu, ncsi, rtc, rcb, etc.

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient for
users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext is added
to support the capability of exporting the name of the corresponding
register and filtering by module names.

This patch adds "filter" and "names" fields to "rte_dev_reg_info"
structure. Names of registers in data fields can be reported and
the registers can be filtered by their module names.
The new API rte_eth_dev_get_reg_info_ext() is added to support
reporting names and filtering by modules. And the original API
rte_eth_dev_get_reg_info() does not use the names and filter fields.
A local variable is used in rte_eth_dev_get_reg_info for
compatibility. If the drivers does not report the names, set them
to "index_XXX", which means the location in the register table.

This patch adds a telemetry command for registers dump,
and supports obtaining the registers of a specified module.
In one way, the number of registers that can be exported
is limited by the number of elements carried by dict and
container. In another way, the length of the string
exported by telemetry is limited by MAX_OUTPUT_LEN.
Therefore, when the number of registers to be exported
exceeds, some information will be lost. Warn on the former
case.
An example usage is shown below:
--> /ethdev/regs,0,ring
{
"/ethdev/regs": {
"registers_length": 318,
"registers_width": 4,
"register_offset": "0x0",
"version": "0x1140011",
"group_0": {
"Q0_ring_rx_bd_num": "0x0",
"Q0_ring_rx_bd_len": "0x0",
...
},
"group_1": {
...
},
...
}

For security reasons, some address registers are not suitable
to be exposed, remove them.

Since the driver dumps the queue interrupt registers according
to the intr_tqps_num, the counter should be the same.

Since the driver is going to support reporting names of
all registers, remove the counter and insert of separators
between different register modules.

This patch adds names for register lists, and support report
names of registers. Some registers has different names on
different platform, use names of HIP08 as default names.

This patch support dumping registers which name contains the
`filter` string. The module names are in lower case and so is
the `filter`. Available module names are cmdq, common_pf,
common_vf, ring, tqp_intr, 32_bit_dfx, 64_bit_dfx, bios, igu_egu,
ssu, ppp, rpu, ncsi, rtc, rcb, etc.

Although the probability is very small, the groups array may overflow if the length is very large.
Suggest add judgement at the begin of this function:
uint32_t max_cap = (RTE_TEL_MAX_DICT_ENTRIES - 4) * RTE_TEL_MAX_DICT_ENTRIES; // it will be 65000+ register
if (reg_info->length > max_cap) {
// just output error and exit
}

It may lead to memory leak when break. If we add such judgement before, there is no need to add such judgement here.
