+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+
+Features
+--------
+
+Features of the zxdh PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+
+Prerequisites
+-------------
+
+- Learning about ZXDH NX Series Ethernet Controller NICs using
+ `<https://enterprise.zte.com.cn/sup-detail.html?id=271&suptype=1>`_.
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+X86-32, Power8, ARMv7 and BSD are not supported yet.

Hi Junlong,
It is very hard to review the driver as a single patch, it helps to
split driver into multiple patches, please check the suggestion on it:
https://patches.dpdk.org/project/dpdk/patch/20240916162856.11566-1-stephen@networkplumber.org/
Also there are errors reported by scripts, please fix them:

we will fix it and use 'RTE_ARCH_X86_64' and 'RTE_ARCH_ARM64' to check,
other comments will be modified, and split the driver into multiple patches.
Thanks!

V5:
- split driver into multiple patches,part of the zxdh driver,
later provide dev start/stop,queue_setup,mac,vlan,rss ,etc.
- fix errors reported by scripts.
- move the product link in zxdh.rst.
- fix meson check use RTE_ARCH_X86_64/RTE_ARCH_ARM64.
- modify other comments according to Ferruh's comments.
V4:
- Resolve compilation issues

+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+- Learning about ZXDH NX Series Ethernet Controller NICs using
+ `<https://enterprise.zte.com.cn/sup-detail.html?id=271&suptype=1>`_.
+
+Features
+--------
+
+Features of the zxdh PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+X86-32, Power8, ARMv7 and BSD are not supported yet.

v6:
- Resolve ci/intel compilation issues.
- fix meson.build indentation in earlier patch.
V5:
- split driver into multiple patches,part of the zxdh driver,
later provide dev start/stop,queue_setup,npsdk_init,mac,vlan,rss ,etc.
- fix errors reported by scripts.
- move the product link in zxdh.rst.
- fix meson check use RTE_ARCH_X86_64/RTE_ARCH_ARM64.
- modify other comments according to Ferruh's comments.
V4:
- Resolve compilation issues
Junlong Wang (9):
net/zxdh: add zxdh ethdev pmd driver
net/zxdh: add logging implementation
net/zxdh: add zxdh device pci init implementation
net/zxdh: add msg chan and msg hwlock init
net/zxdh: add msg chan enable implementation
net/zxdh: add zxdh get device backend infos
net/zxdh: add configure zxdh intr implementation

+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+- Learning about ZXDH NX Series Ethernet Controller NICs using
+ `<https://enterprise.zte.com.cn/sup-detail.html?id=271&suptype=1>`_.
+
+Features
+--------
+
+Features of the zxdh PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+X86-32, Power8, ARMv7 and BSD are not supported yet.

iol-unit-amd64-testing/ Debian 12 | FAIL
DPDK:fast-tests / bitops_autotest FAIL 1.72 s (exit status 255 or signal 127 SIGinvalid)
Do we need to solve this error? We haven't found the detailed reason for the error in the output log. I noticed that the patches submitted by others also have this error.
Thanks.

It was a false positive when testing your series (on top of next-net
repo at the time) and you can ignore this failure.
This is fixed in the main repo with: 899cffe059b8 ("test/bitops: fix
32-bit atomic test spurious failure").
next-net was rebased recently and contains the fix.

Hi, Maintainer
Hope you can take some time to check if there are any modifications needed for the net/zxdh driver.
Thank you very much!

Would be interesting to explain which module is receiving the message.

Why uppercase? for differenciate with vport below?

I am curious about the spinlock function below.
What is it doing exactly?

In general we avoid the pthread.h functions.

You should continue using the prefix ZXDH_
These definitions below have a high risk of namespace conflict in future.
Using a namespace prefix is a good practice.

Removing code is strange here.
Maybe it should have been placed somewhere else initially?

You could use rte_eth_speed_bitflag() instead.

v7:
- add release notes and modify zxdh.rst issues.
- avoid use pthread and use rte_spinlock_lock.
- using the prefix ZXDH_ before some definitions.
- resole issues according to thomas's comments.
v6:
- Resolve ci/intel compilation issues.
- fix meson.build indentation in earlier patch.
V5:
- split driver into multiple patches,part of the zxdh driver,
later provide dev start/stop,queue_setup,npsdk_init,mac,vlan,rss ,etc.
- fix errors reported by scripts.
- move the product link in zxdh.rst.
- fix meson check use RTE_ARCH_X86_64/RTE_ARCH_ARM64.
- modify other comments according to Ferruh's comments.

+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+- Learn about ZXDH NX Series Ethernet Controller NICs using
+ `<https://enterprise.zte.com.cn/sup-detail.html?id=271&suptype=1>`_.
+
+Features
+--------
+
+Features of the ZXDH PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+
+X86-32, Power8, ARMv7, RISC-V, Windows and BSD are not supported yet.

Hi Ferruh,
I hope this message finds you well.
I have made the revisions according to your review comments, and the final version was submitted on Oct 22th. Since then, I have not received any feedback from the community.
I would appreciate it if you could provide any suggestions for modifications. If there is no problem with the submitted driver.
Thank you for your time and assistance.
Thanks!

Again these enums are uppercased and not prefixed.
Please check all other structs which are not prefixed.

It is your driver, so you are free to name functions as appropriate.
But it would make more sense to make the hardware lock follow the pattern
of existing spinlock's etc.

In future, DPDK wants to re-enable the Gcc warning for taking
address of packed member. When I enable that (in config/meson.build)
this shows up.

I am suggesting:
static bool zxdh_try_lock(hw);
void zxdh_release_lock(hw);
also, move the loop into a new function, something like:
int zxdh_timedlock(hw, uint32_t us);

There is no need to initialize a variable like virt_addr which is set later.

v8:
- fix flexible arrays銆乄address-of-packed-member error.
- all structs銆乪num銆乨efine ,etc use zxdh/ZXDH_ prefixed.
- use zxdh_try/release_lock,and move loop into zxdh_timedlock,
make hardware lock follow spinlock pattern.
v7:
- add release notes and modify zxdh.rst issues.
- avoid use pthread and use rte_spinlock_lock.
- using the prefix ZXDH_ before some definitions.
- resole issues according to thomas's comments.
v6:
- Resolve ci/intel compilation issues.
- fix meson.build indentation in earlier patch.
V5:
- split driver into multiple patches,part of the zxdh driver,
later provide dev start/stop,queue_setup,npsdk_init,mac,vlan,rss ,etc.
- fix errors reported by scripts.
- move the product link in zxdh.rst.
- fix meson check use RTE_ARCH_X86_64/RTE_ARCH_ARM64.
- modify other comments according to Ferruh's comments.
