[dpdk-dev] [PATCH 00/12] net/mlx5: add bonding configuration support

[Viacheslav Ovsiienko]

Multiport Mellanox NICs may support the bonding configurations internally.
Let's suppose there is ConnectX-5 NIC with two physical ports, on the host
it presents two PCI physical functions:

- PF0, say with PCI address 0000:82:00.0 and net interface ens1f0
- PF1, say with PCI address 0000:82:00.1 and net interface ens1f1

Also, let's suppose SR-IOV feature is enabled, swithdev mode is engaged,
and there is some set virtual PCI functions and their representor interfaces.
The physical interfaces may be combined into single bond interface,
supported by NIC HW/FW means directly with standard script:

  modprobe bonding miimon=100 mode=4  # 100 ms link check interval, mode - LACP
  ip link set ens3f0 master bond0
  ip link set ens3f0 master bond1

The dedicated Infiniband devices for single ports is destroyed, the new
multiport Infiniband device is created for bond interface and all
representors for both PFs. The unified E-Switch is created either,
and all representor ports belong to the same unified switch domain.

To use the created bond interface with DPDK application both slave
PCI devices must be specified (in whitelist, if any):

  -w 82:00.0,representor=[0-4]
  -w 82:00.1,representor=[0-7]

Representor enumerations follows the VF enumerations in the same way
as for single device. The two PCI devices will be probed, but eth ports
for only one master device and for all representors will be created.
This ports may reference to different rte_pci_dev but share the
same switch domain ID.

The extra devargs specifying configurations must be compatible
(otherwise error on probing will be arisen). For example, it is not
allowed to specify different values of dv_flow_en parameter for
different PCI devices.

[dpdk-dev] [PATCH 01/12] net/mlx5: move backing PCI device to private context

[Viacheslav Ovsiienko]

Now all devices created over the same multiport IB device
have shared context containing the backing PCI device field.
For the VF LAG configurations it becomes possible the
representors might be connected to VF created over different
PFs. In this case representors have the different backing
PCI devices and mentioned field should be moved to device
private area.

[dpdk-dev] [PATCH 02/12] net/mlx5: update PCI address retrieving routine

[Viacheslav Ovsiienko]

The routine mlx5_ibv_device_to_pci_addr() takes Infiniband
device list object, takes the device sysfs path from there
and retrieves PCI address. The routine may be implemented
in more generic way by taking sysfs path directly as parameter
and can be used for getting PCI address of netdevs.

The generic routine is renamed to mlx5_dev_to_pci_addr()

[dpdk-dev] [PATCH 03/12] net/mlx5: allocate device list explicitly

[Viacheslav Ovsiienko]

At device probing the device list to spawn was allocated
as dynamic size local variable. It was no possible to have
one unified exit point from routine due to compiler warnings.
This patch allocates the spawn device list directly with
rte_zmalloc() and it is possible to goto to unified exit
label from anywhere of the routine.

[dpdk-dev] [PATCH 04/12] net/mlx5: add VF LAG mode bonding device recognition

[Viacheslav Ovsiienko]

The Mellanox NICs starting from ConnectX-5 support LAG over
NIC ports internally, implemented by the NIC firmware and hardware.
The multiport NIC presents multiple physical PCI functions (PF),
with SR-IOV multiple virtual PCI functions (VFs) might be presented.
With switchdev mode the VF representors are engaged and PFs and their
VFs are connected by internal E-Switch feature. Each PF and related VFs
have dedicated E-Switch and belong to dedicated switch domain.

If NIC ports are combined to support NIC the kernel drivers introduce
the single unified Infiniband multiport devices, and all only one
unified E-Switch with single switch domain combines master PF
all all VFs. No extra DPDK bonding device is needed.

[dpdk-dev] [PATCH 05/12] net/mlx5: generate bonding device name

[Viacheslav Ovsiienko]

If device is VF LAG bonding one the port name includes
the bonding Infiniband device name and looks like:

  82:00.0_mlx5_bond_0 - for master device port PF0
  82:00.1_mlx5_bond_0_representor_5 - for representor
                                           VF5 over PF1

where bonding Infiniband device mlx5_bond_0 controls
the 82:00.0 as PF0 and 82:00.1 as PF1 PCI functions.

If bonding Infiniband device is found the unified E-Switch

to retrieve vport indices. The patch introduces this feature

to two ones (get E-Switch port parameters by port and
by device pointer) and simplified to returning structure
containing all parameters instead of copying.

There new kernel/rdma_core [1] supports matching on metadata
register instead of vport field to provide operations over
VF LAG bonding configurations. This patch provides correct
translations for flow matchers and destination port actions
if united E-Switch (for VF LAG) is configured and/or new vport
matching mode is engaged.

[dpdk-dev] [PATCH 10/12] net/mlx5: extend switch domain searching range

[Viacheslav Ovsiienko]

With bonding configurations the switch domain may be shared
between multiple PCI devices, we should search the switch
sibling devices within the entire set of present ethernet
devices backed by the mlx5 PMD.

[dpdk-dev] [PATCH 11/12] net/mlx5: update switch port ID in bonding configuration

[Viacheslav Ovsiienko]

With bonding configuration multiple PFs may represent the
single switching device with multiple ports as representors.
To distinguish representors belonging to different PFs we
should generated unique port ID. It is proposed to use
the PF index in bonding configuration to generate this
unique port IDs.

[dpdk-dev] [PATCH 12/12] net/mlx5: check sibling device configurations mismatch

[Viacheslav Ovsiienko]

The devices backed by mlx5 PMD might share the same multiport
Infiniband device context. It regards representors and slaves
of bonding device. These ports are spawned with devargs.
These patch check whether configuration deduced from these
devargs is compatible with configurations if devices
sharing the same context. It prevents the incorrect
whitelists, like:

-w 82:00.0,representor=0,dv_flow_en=1
-w 82:00.0,representor=1,dv_flow_en=0

The representors with indices [0-1] are supposed to spawned
over the same PCi device, but there is dv_flow_en parameter
mismatch.

Hi Slava,

The ICC is failing because of the pragma [1],
- Can you please explain why it is needed, can we escape from it?
- If we can't escape can you please add compiler checks around it? [2]
- And should we enable it as 'error' by default, what about following [3]?


[1]
.../drivers/net/mlx5/mlx5.c(2301): error #2282: unrecognized GCC pragma
  #pragma GCC diagnostic ignored "-Wformat-nonliteral"
                         ^

[2]
#ifdef __GNUC__
#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 1)
#pragma GCC diagnostic ignored "-Wformat-nonliteral"
#endif
#endif


[3]
 #pragma GCC diagnostic push
 #pragma GCC diagnostic ignored "-Wformat-nonliteral"
<...>
 #pragma GCC diagnostic pop

GCC generates error/warning, depending on the settings "-Werror=format-nonliteral",
for the fscanf(file, format, ...) call,  if the "format" parameter is not literal.

> - If we can't escape can you please add compiler checks around it? [2]


Sure, I will. And I'm sorry for missing this in the patch.
BTW , there are multiple usages of "#ifdef __INTEL_COMPILER"
around the GCC pragmas. I think RTE_TOOLCHAIN_GCC is more relevant for the
in case being discussed.

> - And should we enable it as 'error' by default, what about following [3]?
Yes, it would be better, thanks for the nice clue.
