For This patchset just to support the basic chip init work
and user can just found the eth_dev, but can't control more.
For Now just support 2*10g nic,the chip can support
2*10g,4*10g,4*1g,8*1g,8*10g.
The Feature rx side can support rx-cksum-offload,rss,vlan-filter
flow_clow,uncast_filter,mcast_filter,1588,Jumbo-frame
The Feature tx side can supprt tx-cksum-offload,tso,vxlan-tso 
flow director base on ntuple pattern of tcp/udp/ip/ eth_hdr->type
for sriov is also support.

Because of the chip desgin defect, for multiple-port mode
one pci-bdf will have multiple-port (max can have four ports)
so this code must be care of one bdf init multiple-port.

v6:
  * fixed the doc(rst) format problem advise by Thomas Monjalon

v5:
  * fixed the symbol name require by the style documentation

v4:
  * one patch has been forgot to upload :(

v3:
  * fixed http://dpdk.org/patch/129830 FreeBSD 13 compile Issue
  * change iobar type to void suggest by Stephen Hemminger
  * add KMOD_DEP support for vfio-pci
  * change run-cmd argument parse check for invalid extra_args

v2:
  * fixed MAINTAIN maillist fullname format
  * fixed driver/net/meson the order issue of new driver to driver list
  * improve virtual point function usage suggest by Stephen Hemminger

+RNP Poll Mode driver
+====================
+
+The RNP ETHDEV PMD (**librte_net_rnp**) provides poll mode ethdev
+driver support for the inbuilt network device found in the **Mucse RNP**
+
+Prerequisites
+-------------
+More information can be found at `Mucse, Official Website
+<https://mucse.com/productDetail>`_.
+
+Supported Chipsets and NICs
+---------------------------
+
+- MUCSE Ethernet Controller N10 Series for 10GbE or 40GbE (Dual-port)
+
+Limitations or Known issues
+---------------------------
+
+Build with ICC is not supported yet.
+BSD are not supported yet.
+
+CRC stripping
+~~~~~~~~~~~~~
+
+The RNP Soc family Nic strip the CRC for every packets coming into the
+host interface irrespective of the offload configuration.
+When you want to disable CRC_OFFLOAD the operate will influence the rxCksum offload.
+
+VLAN Strip/Filter
+~~~~~~~~~~~~~~~~~
+
+For VLAN strip/filter, RNP just support vlan is CVLAN(0x8100).If the outvlan type is SVLAN(0X88a8)
+VLAN filter or strip will not effort for this packet.It will bypass filter to the host default queue,
+whatever the other filter rule is.

  To: Wenbo Cao; +Cc: dev, ferruh.yigit, thomas, andrew.rybchenko, yaojun

we must get the shape info of nic from Firmware for
reset. so the related codes is first get firmware info
and then reset the chip

Hi Wenbo,

After this patch, driver doesn't implement any of the dev_ops (struct
eth_dev_ops), so I assume it is not functional at all.

But meanwhile patchset has devargs parsing, fw_update, LSC interrupts,
implemented etc.
I think it makes testing/reviewing harder to add more code before basic
device functionality is missing.

What about implementing following main dev_ops and implement a simple
datapath, to have minimum working driver, later add features on top of it:
dev_configure
dev_start
dev_stop
dev_close
dev_infos_get
rx_queue_setup
tx_queue_setup


Also I have comment on putting 'mac_ops' on process_private, I suspect
there is a design problem there, please check details in relevant patch.


Thanks,
Ferruh

I know this is documented in other PMDs too, but at this stage ICC is
supported with best effort, and I am not sure if anybody testing with
it, so I think it is OK to drop this as limitation.

I didn't understand the second sentences, from first one I understand
'RTE_ETH_RX_OFFLOAD_KEEP_CRC' is not supported by the PMD, but can you
please clarify more?

VLAN strip/filter doesn't work for double-tag (QinQ), it only works for
single VLAN tag, is this correct? If so can you please update above
sentences to clarify this?

Is the struct needs to be cache aligned?

Why this additional secondary check is required?
'rte_eth_dev_pci_generic_probe()' should be dealing with
primary/secondary process case.

'rnp_osdep.h' not used at all in the patch, can you move it where it is
used?

All structs seems alligned to the cache, although it may not hurt, it is
better to align ones that is necessary for performance.

Please don't split the log message, instead can do:
RNP_PMD_DRV_LOG(ERR,
	"Could not allocate eth_dev for %s\n",
	name);

Same for all log messages.

This is hardcoded value, so no need the loop below but perhaps it is for
future.

Why 'When' & 'Probe' starts with uppercase, similar usage exists many
places, although that is not an issue, just catches eye, can you please
fix them if there is no specific reason.

'rnp_init_port_resource()' can't return error but perhaps this check is
for future.

This should crash, because 'port' is 'dev_private' and
'rte_eth_dev_release_port()' frees the dev_private, so can't access
'port->' here.

Also 'process_private' set to NULL in the 'rte_eth_dev_release_port()',
it should be freed in 'rnp_dev_close()', not here.

Do you really need two different log types? What about reducing it to one?

I assume mbx is mailbox, can you please use full name in the patch title
and commit log.

How the parties get notified about new messages, is the interrupt
support enabled or polling, can you please elabore the support in the
commit log?

Why there is no meson file in base folder?

Should 'rnp_mbx*' files also go under base folder? I can see they use
some 'u8' like typedef, making me think they are shared between other
platforms, if so base folder suits better.

Base code is mostly for works as HAL and you don't need to pass "struct
rte_eth_dev" in this level, but mostly adapte (struct rnp_eth_adapter)
or hw (struct rnp_hw) should be sufficient.

I assume you are passing "struct rte_eth_dev" because "struct
rnp_mac_api" is stored in 'process_private', this part I am not clear.

Why need 'mac_ops' pointers for secondary process?
Primary process should be doing all hw initialization, otherwise both
primary and secondar(y|ies) trying to configure the MAC can cause
unexpected results.

Seconday process is only for datapath, which can access to the queues
and do packet processing.

Needing "mac_ops" in the secondary can be bad design desicion, can you
please double check it?

There are lots of hardcoded values in this function, can you make them
macros?

As commented above, I am not sure why you need this, it should be
sufficient to have mac_ops in primary proccess.

Isn't 'adapter' shared betwen primary and secondary ('port' is
dev_private and 'port->adapt' is 'adapter'), so updating
"adapter->share_priv" defeats the purpose of process_private, no?

You can add this when it is needed, so in same patch we can see where it
is called and how it is implemented, right now it is not possible that
what 'special' init does.

At this stage port is NULL, probably above needs to go to other patch
that sets 'port'.

With these there are three different macros used to log in
'rnp_drv_logtype' type:

RNP_PMD_LOG
PMD_DRV_LOG
RNP_PMD_DRV_LOG

'RNP_PMD_DRV_LOG' and 'PMD_DRV_LOG' looks exact same, do you need all
these macros, why not stick to one?

If more than one required, can you please comment what is used for what,
and perhaps rename macros in a way that it is clear which one to use
where (as I assume one is specific to base files).

What is "shape info"?

Is there a specific reason to have "Chip Init" start with uppercase, if
not please make all lowercase, also ':' after domain, like "net/rnp:'.

Please document these runtime arguments in the device document.

Also please add 'RTE_PMD_REGISTER_PARAM_STRING()' macros to document
argument for pmdinfogen, please see samples in existing code.

There is already an generic eal argument that lets you select between
vector and scalar datapath implementation:
--force-max-simd-bitwidth=<val>

This patch also enables FW upgrade, can you please detail this in the
commit log? Or even you can consider to split this part into separate patch.

Should free 'dev->data->mac_addrs' here, or even better can be to
implement 'rnp_dev_close()' to free device resources.

I guess the 'port->mac_addr' got from device via 'rnp_get_mac_addr()'
above, but if 'rnp_get_mac_addr()' fails what will be the value. Should
there be check and set a random mac if required?

rte_eth_dev_probing_finish() is not required, as
'rte_eth_dev_pci_generic_probe()' calls it if dev_init() returns success.

These are mac_ops functions, normally the reason to have mac_ops is to
support different HW that behaves slightly different and this difference
managed by different function pointers per device. Is this your usecase?

And since these are mac_ops, defined in the base folder header, it suits
better to have separate .c file for them which is under base file, what
do you think? Or am I getting these mac_ops wrong?

Can you please describe why this 'rnp_special_ops_init()' is for (its
difference from rnp_common_ops_init()) ?

For N10  chip is just have two pcie-bdf, the one pcie-bdf may have multiple port(max 4)
'rte_eth_dev_pci_generic_probe' probe the pcie-pdf port(master port port 0)
the other port alloc by 'rnp_alloc_eth_port', not set 'rte_eth_dev_probing_finish()'
so the 1,2,3 port will set 'rte_eth_dev_probing_finish()'.

This is because for one pcie-bdf one port and one pcie-bdf multiple port usecase
For hareware design limit, we max can support eight port but just have two pcie-bdf.
We must use two set of api to resolve one pcie-bdf one port and
one pcie-bdf multiple port for the port Control independence feature. 
Such as vlan-filter, mac unicast/Multicast filter, promise, Multicast promise, Broadcast promise.
So that some API is common used for one-port-pcie-bdf and  multiple-port-one-pcie-bdf :(.
And some mac-api must change when known the nic is multiple-port mode.

You are right, 😊 mac_ops api need to depart from rnp.c  to a separate.c .

In 'rnp_common_ops_init' both one pcie-bdf one port and one pcie-bdf multiple port,
will  use mailbox to communicase with fireware.
'rnp_special_ops_init() is design to change the mac api when the nic is  multiple-port
mode.
For now, the code is just for one-pcie-one-port mode.

Because of one-pcie-bdf have multiple-port, the hw only manage by the adapter struct
But the adapter struct and hw struct don't have port info(0,1,2,3).
For this problem I can change 'rte_eth_dev'  to struct rnp_eth_port'

User can set api , if 'dev->dev_ops' set don’t  limit.

I refer to some exist driver, it is not special limit for SECONDARY process for 'dev->dev_ops' set.
So when I test some code fond that some api will be cause crash such as 'get_module_eeprom'
And I find this is because of function point api, the secondary process use primary function point api address.
The address for secondary is can't reach. So I try to move the mac_ops, mbx_ops to the process_prive to
resolved this problem. Primary and secondary will have it own  function point api address.

Yes just process private.
dev->process_private; this dev is alloc by 'rte_eth_dev_pci_generic_probe'
So we must record the first port dev->process_private,
when the secondary port of the same PF, alloc by rnp_alloc_eth_port 
we can use lase record info 'adapter->share_priv' turn to
'dev->process_private' (alloc by rnp_alloc_eth_port).

For now, I can remove the code for one pcie-bdf-one-port mode.

Because of multiple port mode single pcie-bdf the other port
Alloc use xx:xx.0_0, xx:xx.0_1, xx:xx.0_2, xx:xx.0_0,  use rnp_alloc_eth_port api.

Because of the chip is just have two pcie-bdf, the can have max eight port,
So rte_eth_dev_pci_generic_probe alloc the first port, the other port is a fake string
Add for x:x.0_1, x:x.0_2, x:x.0_3, so the 'primary_pci' is to mark the real pci_addr

Hi Wenbo,

What is the status of the 'rnp' driver, v7 was expected but not
received, will upstreaming continue for v24.03?

Hi Ferruh,

Thanks for your  reminder, I'm sorry for that I had been work on anothing before.
Recendly, I have been reworked on this work. It will miss on release of v24.03.

For another thing, I'm always confused for the secondary process call like hw->mac_ops this function pointer.
is this method can work normally on secondary process ?
For example,ixgbe on secondary process call ixgbe_get_module_eeprom I fond that it  will cause process core-dump.
because of secondary process use primary process function-point address.
Is dpdk plaform  allowed user call the eth_dev_ops on secondary process?
I don't find any limit and don't know wether or not to protect this function call work normally.
My driver eth_dev_ops achieve will used some function-pointer, so I'm confued about this.
Wish your kind guidance.

Regadrs Wenbo

Hi Wenbo,

"struct rte_eth_dev" is per process, not shared, so both primary and and
secondary has a copy of it.
And during driver initialization, 'eth_dev->dev_ops' is set, so both
primary and secondary processes has correct function pointers.
("struct rte_eth_dev_data" is shared, so any pointer withing that struct
should be in a shared memory between primary and secondaries.)

And there is no restriction for secondary process call 'eth_dev_ops' but
this call needs to be synchronized by application, since there is no
locking around those functions.
Common usecase is primary process runs the control path, uses
'eth_dev_ops' calls, and secondaries only does the datapath on specific
set of queues.


If you are referring to 'mac_ops', that is another layer of abstraction
some drivers use, but those should be tied to ethdev control path
functions eventually, so same rule for using ethdev control path applies
to them.
