To compliance with the coding standard, make the pointer variable
explicitly comparing to 'NULL' and the integer variable explicitly
comparing to '0'.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Unify the type of integer variable to the DPDK prefer style.
Also change the return type of 'nfp_eth_speed2rate()' to the
corresponding enum, which make it more readable.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Add log statement to the important control logic, which means
more strict check of the return value of function call.
Also remove some verbose info log statement.

Add the nfp_dev module to simplify the logic.
The data structure we import can gather and replace several macro
which scatter everywhere. Which also make the logic of choose value
for different devices unnecessary and so eliminate such logic.

Modify the comment and standard the coding style.
Move the definition of data structure into the implement file to make
the API small.
Also sync the logic from kernel driver and remove the unneeded header
file include statements.

From: Chaoyong He @ 2023-08-24 11:09 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Sync the logic from kernel driver, adjust the definition of structure,
and extend the usage of nfp BAR from 8 to 24.
This will greatly enhance the scalability of nfp PMD.

Each parameter of function should occupy one line, and indent two TAB
character.
All the statement which span multi line should indent two TAB character.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Unify the type of integer variable to the DPDK prefer style.
Also change the return type of 'nfp_eth_speed2rate()' to the
corresponding enum, which make it more readable.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Add log statement to the important control logic, which means
more strict check of the return value of function call.
Also remove some verbose info log statement.

- * When the target type can not be used to fully describe the location of a
- * symbol the domain field is used to further specify the location (i.e., the

- * of "sram" symbols for backward compatibility, which are viewed as global.

Add the nfp_dev module to simplify the logic.
The data structure we import can gather and replace several macro
which scatter everywhere. Which also make the logic of choose value
for different devices unnecessary and so eliminate such logic.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Modify the comment and standard the coding style.
Move the definition of data structure into the implement file to make
the API small.
Also sync the logic from kernel driver and remove the unneeded header
file include statements.

To: dev; +Cc: oss-drivers, niklas.soderlund, Chaoyong He
Sync the logic from kernel driver, adjust the definition of structure,
and extend the usage of nfp BAR from 8 to 24.
This will greatly enhance the scalability of nfp PMD.

To: dev; +Cc: oss-drivers, Chaoyong He, Niklas Söderlund
Unify the type of integer variable to the DPDK prefer style.
Also change the return type of 'nfp_eth_speed2rate()' to the
corresponding enum, which make it more readable.

From: Chaoyong He @ 2023-09-15 9:15 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, Chaoyong He, Niklas Söderlund
Add log statement to the important control logic, which means
more strict check of the return value of function call.
Also remove some verbose info log statement.

The data structure we import can gather and replace several macro
which scatter everywhere. Which also make the logic of choose value
for different devices unnecessary and so eliminate such logic.

To: dev; +Cc: oss-drivers, Chaoyong He, Niklas Söderlund
Modify the comment and standard the coding style.
Move the definition of data structure into the implement file to make
the API small.
Also sync the logic from kernel driver and remove the unneeded header
file include statements.

To: dev; +Cc: oss-drivers, Chaoyong He, Niklas Söderlund
Sync the logic from kernel driver, adjust the definition of structure,
and extend the usage of nfp BAR from 8 to 24.
This will greatly enhance the scalability of nfp PMD.

No objection to it, but "Each parameter of function should occupy one
line" is NOT coming from DPDK coding convention, right?
If this is for driver code consistancey, that is OK.

'%lx' is not portable between 32bits and 64bits architectures,
when using fixed size variables, like 'uint64_t', better to use 'PRIx64'
macro,
although I know driver is only compiled for 64bits.

As I see some comments are removed in this patch, there is no enforced
comment style for internal functions, for API doxygen comments must
provided.
Of course consistency matters, but if comments are removed because of
the syntax, I think better option to keep them with their own syntax.

DPDK memory management APIs are required for datapath, where it matters
from which socket it is allocated, it is accessed a lot (datapath), or
it is shared between primary & seconday processes.
But memory for the control path come from regular heap, and perhaps that
is even better as it doesn't fragment the DPDK memory space, @Anatoly
can comment better on it.
Briefly, if there is no reason to the otherwise, I suggest keep using
malloc()/free().

What is the motivation for this move, I can see same is done in multiple
other patches?
Header file is still included by .c file, what is the benefit of moving
from header to .c file?

Hi Chaoyong, Niklas,
I put some comments on patches, mostly minor comments, only critical one
is the decision to use rte memory management widely or not, please check
comments.

Yes, it's our own coding style, a little stricter than the DPDK coding convention.

Sorry for that, we may be missing some when rebase the code, we will check and add them.
Thanks.

We try to make the interface between modules as small as possible.
We meet some problem when we add new features, too much content in the header files make it difficult to form a identify dependencies among modules.
When we try to add a new data field in a structure or add a new data type in one header file, we had to modify many unrelated files just because it includes this header file, it's not good.
This is the direct motivation for this move, this will make the development easier.

Oh, I understand what you mean now.
We are not removing it, we just keep the comment of functions in the place where it was defined (the implement file).
I will make it clear in the commit message in the next version, thanks.

I wish DPDK had a uniform style and use one of the styles describable
by the clang-format settings.

v4:
* Drop the commit 'using the DPDK memory management API'.
* Modify the commit message of 'standard the comment style'.
* Revise some comment logic as the advice of reviewer.
v3:
* Fix one bug in the BAR find logic.
* Modify more coding style.
v2:
* Fix the compile error in Fodora 37 environment.

To compliance with the coding standard, make the pointer variable
explicitly comparing to 'NULL' and the integer variable explicitly
comparing to '0'.

To: dev; +Cc: Chaoyong He, Niklas Söderlund
Unify the type of integer variable to the DPDK prefer style.
Also change the return type of 'nfp_eth_speed2rate()' to the
corresponding enum, which make it more readable.

From: Chaoyong He @ 2023-09-18 2:45 UTC (permalink / raw)
To: dev; +Cc: Chaoyong He, Niklas Söderlund
Add log statement to the important control logic, which means
more strict check of the return value of function call.
Also remove some verbose info log statement.

The data structure we import can gather and replace several macro
which scatter everywhere. Which also make the logic of choose value
for different devices unnecessary and so eliminate such logic.

From: Chaoyong He @ 2023-09-18 2:46 UTC (permalink / raw)
To: dev; +Cc: Chaoyong He, Niklas Söderlund
Modify the comment and standard the coding style.
Move the definition of data structure into the implement file to make
the API small.
Also sync the logic from kernel driver and remove the unneeded header
file include statements.

To: dev; +Cc: Chaoyong He, Niklas Söderlund
Sync the logic from kernel driver, adjust the definition of structure,
and extend the usage of nfp BAR from 8 to 24.
This will greatly enhance the scalability of nfp PMD.

If you can move a struct or data type to .c file, it means it is not
shared so updating it should not cause change anyway.
I am not against it, but I didn't get your reasoning.
When there are 'nfp_hwinfo.c' and 'nfp_hwinfo.h' files, I think that is
reasonable to have "nfp_hwinfo*" macros and structs in the .h file, it
looks like you want to separate data structures that are shared and ones
that are only used by 'nfp_hwinfo.c' but I am not sure how it helps.
Anyway if you know what you are doing, it is OK, I just want to double
check if this is done on purpose.

I have not reviewed this rebase, I'm sure it's fine, but I have not
reviewed it. Please drop my R-b from any future postings.

One of the previous patches, patch 3/27, updates variable type
'unsigned int max_size;' -> 'size_t max_size;'
Now it is updated again to 'uint32_t max_size;', I assume by mistake
that previous patch updated by this one didn't.
If it is by mistake can you please check all patches that moves code, if
they are aligned with previous cleanups.
Or if this is intentional, can you please update the first patch to set
the variable correct at first place?

This patch series aims to:
- Make the coding style satisfy with DPDK.
- Sync the logic with kernel driver.
- Make the sub-module more modular.
- Extend the nfp configure BAR from 8 to 24.

v5:
* Fix one bug in the logic of VF using dev module.
* Remove the R-b tag as the requirement of Niklas.
* Revise logic follow the advice of reviewer.
v4:
* Drop the commit 'using the DPDK memory management API'.
* Modify the commit message of 'standard the comment style'.
* Revise some comment logic as the advice of reviewer.
v3:
* Fix one bug in the BAR find logic.
* Modify more coding style.
v2:
* Fix the compile error in Fodora 37 environment.

Each parameter of function should occupy one line, and indent two TAB
character.
All the statement which span multi line should indent two TAB character.

To: dev; +Cc: oss-drivers, Chaoyong He
Unify the type of integer variable to the DPDK prefer style.
Also change the return type of 'nfp_eth_speed2rate()' to the
corresponding enum, which make it more readable.

From: Chaoyong He @ 2023-09-19 9:54 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, Chaoyong He
Add log statement to the important control logic, which means
more strict check of the return value of function call.
Also remove some verbose info log statement.

From: Chaoyong He @ 2023-09-19 9:54 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, Chaoyong He
Add the nfp_dev module to simplify the logic.
The data structure we import can gather and replace several macro
which scatter everywhere. Which also make the logic of choose value
for different devices unnecessary and so eliminate such logic.

Modify the comment and standard the coding style.
Move the definition of data structure into the implement file to make
the API small.
Also sync the logic from kernel driver and remove the unneeded header
file include statements.

From: Chaoyong He @ 2023-09-20 1:29 UTC (permalink / raw)
To: dev; +Cc: oss-drivers, Chaoyong He
Sync the logic from kernel driver, adjust the definition of structure,
and extend the usage of nfp BAR from 8 to 24.
This will greatly enhance the scalability of nfp PMD.

Sorry, the send email command failed after the 24/26 patch has send out, and I'm not found that.
$ git send-email --to dev@dpdk.org --cc oss-drivers@corigine.com --in-reply-to 20230918024612.1600536-1-chaoyong.he@corigine.com ./*.patch

...propagated at /usr/libexec/git-core/git-send-email line 1694.
This is the first time I meet this problem, and it's my fault did not notice it, and I still not sure what cause it.
I re-send the 25/26 and 26/26 patch with the same command (except the './*.patch' part), but seems they are not recognized as the same series in the patchwork:
Untitled series #29559
Untitled series #29560
How to fix that or should I send a v6 version for the whole series?

Same here, error is not familiar and not sure about root cause.

That is OK, I will get missing patches manually.
