Is *addr CIO memory or a MMIO register?
Looking at the patch 20/22, it should be a MMIO register. Whether a barrier is required depends on preceding accesses, so advise move the barrier out.

If *addr is CIO memory, rte_cio_rmb is enough, rte_mb is overkilling.
If *addr is MMIO register, rte_rmb one-way barrier is also adequate.
Whether this barrier is required is depending on the following accesses, also advise to move out.
This API should not includes barriers inside as a common API.

Gcc/clang provides '__atomic' builtins to replace the legacy '__sync' builtins, new code should always use the '__atomic' builtins rather than the '__sync' builtins.
This function can be replaced with __atomic_fetch_or(addr, (1UL << nr), __ATOMIC_RELAXED);

addr is a shared variable address between threads, we will remove the
memory barrier, and use atomic read __atomic_load_n as below:
static inline uint64_t
hns3_atomic_test_bit(unsigned int nr, volatile uint64_t *addr)
{
uint64_t res;
res = (__atomic_load_n(addr, __ATOMIC_RELAXED) & (1UL << nr)) != 0;
return res;
}
Thanks for your suggestion.

OK, we will update and replace it with __atomic_xxx in patch V2.
Thanks for your suggestion.

Are all these headers really used at this stage? Can you please clean them and
add later patches when they are required?

I think no need to call 'rte_eth_copy_pci_info()', it is called by
'rte_eth_dev_pci_generic_probe()' before 'hns3_dev_init()' called.

There is a separate VF driver, is this field still needed?

Init should set 'RTE_ETH_DEV_CLOSE_REMOVE' flag, and '.dev_close' should free
the driver allocated resources, which there is not up until this patch:
+eth_dev->data->dev_flags |= RTE_ETH_DEV_CLOSE_REMOVE;

hns3 PMD driver includes PF and VF drivers.
In the struct hns3_adapter data, the memeber named is_vf is used to
distinguish PF from VF devices.

This definition is used by 'hns3_ethdev.h' but moved to 'hns3_cmd.h', and
'hns3_ethdev.h' doesn't include 'hns3_cmd.h', which will force whatever .c file
include 'hns3_ethdev.h' to include 'hns3_cmd.h' before it and these kind of .h
order dependencies are easy to break.
Would it work if 'hns3_ethdev.h' includes 'hns3_cmd.h'

We support reset after exception, and restore the settings to the
pre-reset by the alarm in the interrupt thread. There are two threads
setting mc_mac, so we need to lock.

If 'hns3_dev_infos_get()' sets 'min_mtu' & 'max_mtu' properly, above check will
be done by 'rte_eth_dev_set_mtu()' already.

'RTE_ETHER_MIN_MTU' is default value and can be skipped.

This patch adds support for flow directory of hns3 PMD driver.
Flow directory feature is only supported in hns3 PF driver.
It supports the network L2\L3\L4 and tunnel packet creation,
deletion, flushing, and querying hit statistics.

'hns3_dev_filter_ctrl()' is not exists up until this patch.
This is the problem of not enabling the driver yet, it is very hard to see these
kind of issues. When Makefile/meson patch moved to the begging of the patches
and start to build the driver, these issues will be visible.

This patch adds support for RSS of hns3 PMD driver.
It included the following functions in file hns3_rss.c:
1) Set/query hash key, rss_hf by .rss_hash_update/.rss_hash_conf_get ops
callback functions.
2) Set/query redirection table by .reta_update/.reta_query. ops callback
functions.
3) Set/query hash algorithm by .filter_ctrl ops callback function when
the 'filter_type' is RTE_ETH_FILTER_HASH.
And it included the following functions in file hns3_flow.c:
1) Set hash key, rss_hf, redirection table and algorithm by .create ops
callback function.
2) Disable RSS by .destroy or .flush ops callback function.
3) Check the effectiveness of the RSS's configuration by .validate ops
callback function.

Legacy filter API is deprecated, there is a recent patch from Thomas to
deprecate documenting this as feature:

Can you please update .ini file in this patch and mark following features as
supported:
RSS key update
RSS reta update
For 'RSS hash' datapath update is also required, I am not sure in which patch
that support it added.

We will remove some related feature, and send patch V2.

This patch adds support for MAC PAUSE flow control and priority flow
control of hns3 PMD driver. All user priorities(up) must be mapped to
tc0 when MAC PAUSE flow control is enabled. Ups can be mapped to other
tcs driver permit when PFC is enabled. Flow control function by default
is turned off to ensure that app startup state is the same each time.

As far as I can see the patch both enable DCB and flow control, can you please
either split the patch or update the commit log to cover both features?

Hi, Ferruh Yigit
Thanks for your comments.
We will modify the commit log in patch V2 as follows:
This patch adds support for MAC PAUSE flow control and priority flow
control(PFC).
MAC PAUSE flow control features:
All user priorities(up) are mapped to tc0. It supports settings of flow
mode and pause time.
DCB features:
Up can be mapped to other tc driver permits according to business
requirement. We can config DCB information and enable PFC by
rte_eth_dev_configure interface. Besides, enabling flow control of a
priority is supported by rte_eth_dev_priority_flow_ctrl_set interface.
we can also set flow mode and pause time by
rte_eth_dev_priority_flow_ctrl_set. we do not support manual setting of
ETS, but driver equally distributes bandwidth for each tc according to
number of used tc.
In addition, flow control function by default is turned off to ensure
that app startup state is the same each time.

Why need to include the new header if .c file is not using from the header? Same
for other .c files below.

Same comment for all .c files in the driver, above inclusion list feels like a
copy/paste, can you please include only necessary headers?

This patch adds support for hns3 VF PMD driver.
In current version, we only support VF device is bound to vfio_pci or
igb_uio and then taken over by DPDK when PF device is taken over by kernel
mode hns3 ethdev driver, VF is not supported when PF devcie is taken over
by DPDK.

I think better to say 'when PF is driven by DPDK driver' than 'when PF device is
taken over by DPDK'.
Can you please this (VF only supported when PF is driver by kernel) in your
documentation please?
And perhaps VF driver support in feature list to highlight it...

'hns3_dev_supported_ptypes_get' has been defined in previous patch, what do you
thinks defining and using in same patch?

This patch adds reset related process for hns3 PMD driver.
The following three scenarios will trigger the reset process,
and the driver settings will be restored after the reset is
successful:
1. Receive a reset interrupt
2. PF receives a hardware error interrupt
3. VF is notified by PF to reset

This patch adds multiple process support for hns3 PMD driver.
Multi-process support selection queue by configuring RSS or
flow director. The primary process supports various management
ops, and the secondary process only supports queries ops.
The primary process notifies the secondary processes to start
or stop tranceiver.

We limit the slave process to only perform query ops actions, and cannot
perform configuration ops actions to prevent the master and slave
processes from performing configuration ops at the same time, which may
cause conflicts.

When the primary process executes dev_stop, it will release the mbuf of
all rx queues. The secondary process may access the mbuf of the rx
queue, and a segmentation error will occur.So MP is used in
multi-process to solve this problem. When primary process executes
dev_stop, it informs the process to stop receiving, and then releases
the mbuf, so that the secondary process will not have a segmentation error.

+HNS3 Poll Mode Driver
+===============================
+
+The Hisilicon Network Subsystem is a long term evolution IP which is
+supposed to be used in Hisilicon ICT SoCs such as Kunpeng 920.
+
+The HNS3 PMD (librte_pmd_hns3) provides poll mode driver support
+for hns3(Hisilicon Network Subsystem 3) network engine.
+
+Features
+--------
+
+Features of the HNS3 PMD are:
+
+- Arch support: ARMv8.
+- Multiple queues for TX and RX
+- Receive Side Scaling (RSS)
+- Packet type information
+- Checksum offload
+- Promiscuous mode
+- Multicast mode
+- Port hardware statistics
+- Jumbo frames
+- Link state information
+- VLAN stripping
+- NUMA support
+
+Prerequisites
+-------------
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_HNS3_PMD`` (default ``y``)
+
+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
+---------------------------
+Build with clang is not supported yet.
+Currently, only ARMv8 architecture is supported.

Is it an integrated NIC controller? Why it is supported only on ARMv8?
The reason why I asking because, Enabling CONFIG_RTE_LIBRTE_HNS3_PMD=y
only on arm64 will create a case where build fails for arm64 and passes for
x86. I would like to avoid such disparity. If the build is passing on x86 make it
enable in the common code, not in arm64 config.

Currently this network engine is integrated in the SoCs, the SoCs can be
used
as a PCIe EP integrated NIC controllers or be used as universal cpus on
the device,
such as servers. The network engine is accessed by ARM cores in the SoCs.
We will enabling CONFIG_RTE_LIBRTE_HNS3_PMD=y in common_linux config in V2.
Thanks.

Hi, Jerin
as a PCIe EP integrated NIC controllers -> as a PCIe EP Intelligent
NIC controllers
Since it is currently only accessed by ARM cores on SoCs,
maybe it is also reasonable to compile only on ARMv8, right?

This sentence needs some editing to remove marketing speak.
It is not clear what "long term evolution IP" means when read
by a DPDK user. Why not just say that "Hisilcon Network Subsystem
(HNS) is used in System On Chip (SOC) devices such as the Kunpeng 920".
It is standard practice in technical documents to spell out
the meaning of acronyms on first use; then use the acronym
there after.

Pleas fix this. You need to add new line at end of
file. Vi does this by default, and Emacs has an option
to do this.

Just set below line in .emacs would work, Stephen told me last time :).

I can understand the architecture ones, but why clang is not supported? Can you
please add this support?

There is better way to do this in meson, please check other samples. But as the
makefile comment, does it really needed, if so can you please add the
experimental APIs used as a comment, to both meson and Makefile?

The official website link of kunpeng920 chip is not available yet,
And we will paste the link to the servers product using kunpeng920 in

There are some APIs as follows in hns3 PMD driver,
'-DALLOW_EXPERIMENTAL_API' can clear warning during compiling.

I will update it as follows:
allow_experimental_apis = true
# Experimantal APIs:
# - rte_mp_action_register

There are separate PF and VF drivers in the patchset, this is mostly represent
by to different .ini files, hns3.ini and hns3_vf.ini, and can you please reflect
the feature differences into these files?

There are some build error for 32-bit [1], I am aware that 32-bit is not in the
supported arch list, but build error are just related to the log format
identifiers, it is good practice to use 'PRIx64' and friends which will also fix
the build issue.
