[patch net-next RFC 00/12] devlink: introduce port flavours and common phys_port_name generation

[Jiri Pirko]

From: Jiri Pirko <jiri@mellanox.com>

This patchset resolves 2 issues we have right now:
1) There are many netdevices / ports in the system, for port, pf, vf
   represenatation but the user has no way to see which is which
2) The ndo_get_phys_port_name is implemented in each driver separatelly,
   which may lead to inconsistent names between drivers.

This patchset introduces port flavours which should address the first
problem. I'm testing this with Netronome nfp hardware. When the user
has 2 physical ports, 1 pf, and 4 vfs, he should see something like this:
# devlink port
pci/0000:05:00.0/0: type eth netdev enp5s0np0 flavour physical number 0
pci/0000:05:00.0/268435456: type eth netdev eth0 flavour physical number 0
pci/0000:05:00.0/268435460: type eth netdev enp5s0np1 flavour physical number 1
pci/0000:05:00.0/536875008: type eth netdev eth2 flavour pf_rep number 536875008
pci/0000:05:00.0/536870912: type eth netdev eth1 flavour vf_rep number 0
pci/0000:05:00.0/536870976: type eth netdev eth3 flavour vf_rep number 1
pci/0000:05:00.0/536871040: type eth netdev eth4 flavour vf_rep number 2
pci/0000:05:00.0/536871104: type eth netdev eth5 flavour vf_rep number 3

The indexes are weird numbers now. That needs to be fixed. Also, netdev
renaming does not work correctly for me now for some reason.
Also, there is one extra port that I don't understand what
is the purpose for it - something nfp specific perhaps.

The desired output should look like this:
# devlink port
pci/0000:05:00.0/0: type eth netdev enp5s0np0 flavour physical number 0
pci/0000:05:00.0/1: type eth netdev enp5s0np1 flavour physical number 1
pci/0000:05:00.0/2: type eth netdev enp5s0npf0 flavour pf_rep number 0
pci/0000:05:00.0/3: type eth netdev enp5s0nvf0 flavour vf_rep number 0
pci/0000:05:00.0/4: type eth netdev enp5s0nvf1 flavour vf_rep number 1
pci/0000:05:00.0/5: type eth netdev enp5s0nvf2 flavour vf_rep number 2
pci/0000:05:00.0/6: type eth netdev enp5s0nvf3 flavour vf_rep number 3

As you can see, the netdev names are generated according to the flavour
and port number. In case the port is split, the split subnumber is also
included.

I tested this for mlxsw and nfp. I have no way to test this on DSA hw,
I would really appretiate DSA guys to test this. Thanks!

[patch net-next RFC 01/12] devlink: introduce devlink_port_attrs_set

[Jiri Pirko]

From: Jiri Pirko <jiri@mellanox.com>

Change existing setter for split port information into more generic
attrs setter. Alongside with that, allow to set port number and subport
number for split ports.

[patch net-next RFC 02/12] devlink: extend attrs_set for setting port flavours

[Jiri Pirko]

From: Jiri Pirko <jiri@mellanox.com>

Devlink ports can have specific flavour according to the purpose of use.
This patch extend attrs_set so the driver can say which flavour port
has. Initial flavours are:
physical, pf_rep, vf_rep, cpu, dsa
User can query this to see right away what is the purpose of each port.

Well, I added the next 2 in previous the patch.

[patch net-next RFC 03/12] devlink: introduce a helper to generate physical port names

[Jiri Pirko]

From: Jiri Pirko <jiri@mellanox.com>

Each driver implements physical port name generation by itself. However
as devlink has all needed info, it can easily do the job for all its
users. So implement this helper in devlink.

Hi Jiri

Please could you explain what you are trying to achieve with this call to 
dsa_port_link_register_of(dp);

Thanks

Ah, i get it. These used to be two case statements with one code
block. But you split them apart, so needed to duplicate the
dsa_port_link_register.

Unfortunately, you forgot to add a 'break;', so it still falls
through, and overwrites the port flavour to DSA.

You don't need hardware, there is drivers/net/dsa/dsa_loop.c which will
emulate a DSA switch. It won't create interconnect ports, since only one
switch can be created with the method chosen, but this would have helped
you catch the missing break since the "CPU" port would have been
displayed as "DSA" anyway.

If you need hardware, I am sure this can be somehow arranged. By that, I
mean something on which you can run upstream Linux on without out of
tree patches.

Hmm, trying to use dsa_loop. Doing:
modprobe dsa_loop
modprobe fixed_phy

I don't see the netdevs. Any idea what am I doing wrong? Thanks!

Yes, modprobe dsa-loop-bdinfo first, which will create the
mdio_board_info and then modprobe dsa-loop.

That is compiled inside "fixed_phy", isn't it?
In my case, "Module fixed_phy is builtin"
So it should be enough just to "modprobe dsa_loop", right? That does not
work :/

Nope.

It follows a pattern seen with I2C and SPI subsystem. A bus driver
provides a bus to Linux. But i2c and SPI, unlike PCI or USB, you
cannot enumerate the devices on the bus, you need to know what devices
are there. So the board file registers an info structure, listing what
devices are on the bus. When the bus pops into existence, the core
links the bus to the info structure about devices on the bus and then
probes the devices.

The same is happening here. The fixed_phy driver provides an MDIO bus.

The info structure in dsa-loop-bdinfo says there is an dsa-loop device
at address 31 on that bus.

Combine the two causes the dsa-loop device to actually probe.

I understand. Yet I have no dsa_loop_bdinfo.ko module. In my .config I
have:
CONFIG_FIXED_PHY=y
CONFIG_NET_DSA_LOOP=m

I had to do this:

diff --git a/drivers/net/dsa/Makefile b/drivers/net/dsa/Makefile
index 15c2a831edf1..2d773d3a7d49 100644

Now dsa_loop_bdinfo.ko gets compiled. I have no clue why it does not
work without the patch :O "obj-$(CONFIG_FIXED_PHY)" doesn't work.

It matches what CONFIG_FIXED_PHY is, so if it's built-in it also becomes
built-in, if is modular, it is also modular, this was fixed with
40013ff20b1beed31184935fc0aea6a859d4d4ef ("net: dsa: Fix functional
dsa-loop dependency on FIXED_PHY")

There is a caveat that if you have everything modular, if you loaded
fixed_phy first, and forgot to load dsa-loop-bdinfo, then nothing will
happen because the MDIO bus was created and there were no matching devices.

Send me your .config and I will take a look. Attached is mine (64Bit x86

Now I have it compiled as module, and after modprobe dsa_loop I see:
[ 1168.129202] libphy: Fixed MDIO Bus: probed
[ 1168.222716] dsa-loop fixed-0:1f: DSA mockup driver: 0x1f

This messages I did not see when I had fixed_phy compiled as buildin.

But I still see no netdevs :/

The platform data assumes there is a network device named "eth0" as the
parent device, yes I know this is terrible, but unfortunately we don't
have anything better at this point, though that could certainly change
that to take a proper struct device reference in the future.

I am assuming that you don't have such a network device named "eth0" in
your system? You can also look at the less than 360 LOCs of the driver
and find out where your problem is, this is not mlxsw :)

That is something we need to solve. With DT, it is easy, we have a
phandle to a device, and the name does not matter. systemd can rename
eth0 to enp0s25 and we will still find it, because we don't look for
the name, we look for the OF node associated to the device.

For platform data driven devices, we don't have this luxury. I have an
intel board with a Marvell switch. I have Debian running on it, so
systemd renames the interface. Builtin vs modules then becomes an
issue. Does the switch driver probe before or after systemd renames
the interface?

For embedded systems like this, we probably need a way to find an
interface based on its bus location, not its name. Not as good, but
maybe sufficient, a function which gives us the first physical
interface the machine has.

Oups, I missed, I created dummy device and modprobed again. Now I see:

$ sudo devlink port
mdio_bus/fixed-0:1f/0: type eth netdev lan1
mdio_bus/fixed-0:1f/1: type eth netdev lan2
mdio_bus/fixed-0:1f/2: type eth netdev lan3

mdio_bus/fixed-0:1f/9: type notset
mdio_bus/fixed-0:1f/10: type notset
mdio_bus/fixed-0:1f/11: type notset

I wonder why there are ports 4-11

Yeah, I'm a bit lost in the embedded/dsa world :)

Hi Jiri

        ds = dsa_switch_alloc(&mdiodev->dev, DSA_MAX_PORTS);

It is allocating a switch with 12 ports. However only 4 of them have
names. So the core only creates slave devices for those 4.

This is a useful test. Real hardware often has unused ports. A WiFi AP
with a 7 port switch which only uses 6 ports is often seen.

Hi Florian, Jiri

Maybe it is better to add a devlink port type unused?

The port does not exist on the switch, so it should not even be
registered IMHO.

Hi Florian

The ports do exist, when you called dsa_switch_alloc() you said the
switch has 12 ports.

What benefit does it have to register unused ports? What is a usecase
for them. Like Florian, I also think they should not be registered.

Hi Jiri

They physically exist, so we are accurately describing the hardware by
registering them.

You are right that the driver is advertising a number of ports that does
not match what is being expected. We unfortunately do not have a good
API for specifying e.g: a sparse port allocation.

[patch net-next RFC 07/12] nfp: flower: fix error path during representor creation

[Jiri Pirko]

From: Jiri Pirko <jiri@mellanox.com>

Don't store repr pointer to reprs array until the representor is
successfully created. This avoids message about "representor
destruction" even when it was never created. Also it cleans-up the flow.
Also, check return value after port alloc.

This will associate the PF netdev with physical port, incl. all ethtool
information.  Im not sure we want to do that.  phy_repr carries this
functionality.

I was not sure originally what this port is. Okay, what I would like to
see is another port flavour for "pf" and "vf". I guess that since the pf
has the same pci address, it would fall under the same devlink instance.
For vfs, which have each separate pci address, I would like to create
devlink instance for each and associate with one devlink port flavour
"vf".

Why do we need a devlink instance and phys port name for vfs?  Just
wondering..  It seems they should be covered by having different bus
address.  For full coverage of all netdevs?

It is a matter of identification I believe. Pfs are under the same pci
address for nfp right? I think that user has to see then and
distinguish. For VFs and nfp, I agree this is probably not necessary, as
the pci address is different and there is also a different driver name.
But for mlx5 for example, the same driver name is shown for all netdevs
including VFs.

Since devlink knows the info needed to generate the physical port name
in a generic way for all devlink users, use the helper to do the job.

Yeah, it is really needed. I would like to fix this jungle so all
drivers behave the same. Started with nfp as they are leading with what
they have implemented. But I expect others to join in (please).

Many drivers just create devlink instance without any ports. Odd. I will
write some Documentation file as a part of this patchset. Also, I'm
thinking about adding some warnings in care driver does some crippled
implementation.

Similar to ndo_get_phys_port_{name,id}, devlink requires drivers to opt
in with an implementation right, so you can't really force a solution to
the consistent naming.

How about 'kind' instead of flavo{u}r?

'kind' is good too...but to not confuse it with logical device
rtnetlink 'kind', maybe 'physical_kind' or 'port_kind' or 'phys_kind'
or any-other-better--prefix-to-kind would be preferable

Yeah, drivers would still have free choice to implemen the ndo
themselves. But most of them, like all sriov switch drivers should use
the devlink helper to have consistent naming. In other words, devlink
helper should be the standard way, in weird cases (like rocker), driver
implements it himself.

Yeah, kind is often used in kernel already with different meaning
git grep kind net/core

That's an assumption that somehow the devlink API will be better
supported than ndo_get_phys_port_{name,id}. Don't get me wrong -- an API
to show the kind of device is needed, but I do not think this enforces
any kind of consistency in naming.

Roopa's amendment works as well; I just think flavor / flavour is the
wrong word. Make me thinks of food ... ice cream vs netdevices.

Naming it a 'subtype' could also work.  It's a bit longer than 'kind'
(no longer than 'flavour') and accurately describes the characteristic
of this port.  It also avoids the namespace collision of 'kind' that
Jiri points out.

It also fits with the names used in the PCI world with vendor:device and
subsystem vendor:subsystem device naming used there for further
granularity.

Problem with "subtype" is that it indicates some relation with type.
We have type:
enum devlink_port_type {
        DEVLINK_PORT_TYPE_NOTSET,
        DEVLINK_PORT_TYPE_AUTO,
        DEVLINK_PORT_TYPE_ETH,
        DEVLINK_PORT_TYPE_IB,
};

Does not feel correct to have subtypes VF/PF/VFREP/etc, which really has
no relation to ETH/IB

What about "role"? Also does not sound good to me, as the "role"
indicates that the port can "act" like something.

For me the "flavour/flavor" is still a favourite. Tells how the port tastes
like, in a semi-fun way :)
Also, there is a precedence to this in particle physics:
https://en.wikipedia.org/wiki/Color%E2%80%93flavor_locking
I guess they also had troubles to find the right name :)

This naming is something we won't want with DSA. We get the port names
from device tree, and they are supposed to reflect the name of the
port printed on the label on the case. So this is often wan, lan0,
lan1, lan2, lan3, etc. That is much more intuitive than enp5s0.

Do you mean the PF netdev?  There can be multiple of those on
multi-host cards.  There is one pf_repr from ASIC's perspective and a
full-blown PF netdev which should be used by applications.  pf_repr is
only for switch config.

Hi Jiri

With the missing break added, i get:

This is on a board with a DSA cluster of three switches. Some of the
switch ports are not connected to anything, so are plain 'notset'.

What is the "number X" meant to mean?

Okay. That looks fine. I wonder if it would make sense to have another
flavour for "unused" ports.


>
>What is the "number X" meant to mean?

That is basically front panel number for physical ports. It is used for
generating phys_port_name. It should have separate numbering for cpu
ports and dsa ports most probably. Although, since they have no
netdevice associated, the number is not used and only shown here.

In case of mlxsw switch port 1, the netdev name is then
for example: "enp3s0np1".

You cannot make that assumption. As you can see here, we have 3 ports
with the number 0.

Look at clearfog, armada-388-clearfog.dts. port 0=lan5, port 1=lan4
port 2=lan3, port 3=lan2, port 4=lan1, port 5=cpu, port 6=lan6.

The hardware and mechanical engineer is free to wire switch ports to
the front panel however they want. That is why we put the netdev name
in device tree.

Got it. Hmm, so I think that the port number can be made optional and
when it is present, it would be used to generate phys_port_name. If
not, perhaps devlink port index could be used instead.

So iiuc, you don't really need phys_port_name in dsa, as it provides
misleading names, right? Why is it implemented then?

We do need phys_port_name because there are switch configuration operations, e.g: ethtool::rxnfc which take a port number and queue number as part of the action to redirect a packet for instance. There is no way to obtain this physical port number other than either knowing it and hard coding it (not great) or scanning the device tree and look for the "reg" property value. phys_port_name gets you that and it is easy for an application to scan /sys/class/net/ on startup to get to know that (and other stuff as well).

There is no way to obtain this physical port number other than either knowing it and hard coding it (not great) or scanning the device tree and look for the "reg" property value. phys_port_name gets you that and it is easy for an application to scan /sys/class/net/ on startup to get to know that (and other stuff as well).

Hmm. That sounds like misuse of phys_port_name. The original purpose was
to provide names as they are actually written on the front panel.

Ok, if we look back at the history of the changes I had implemented ndo_phys_port_id() to return the port number initially, but this was wrong and reverted based on your feedback, and then ndo_phys_port_name() was implemented with your reviewed-by tag:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/dsa/slave.c?id=3a543ef479868e36c95935de320608a7e41466ca
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/dsa/slave.c?id=592050b2541407d033da18226d3644644832d082

Now that this is reported through sysfs it unfortunately becomes ABI and we should not be breaking user applications relying on that and there is at least one I know of...

What is an appropriate attribute to use to return the physical port number within a given switch?

Florian, do you need it to be unique per switch, or DSA cluster. The
current solution is clearly not unique across a cluster.

It needs to be unique per switch, we have the switch identifier through
phys_switch_id for higher level "uniqueness".

Hi Jiri

Isn't the same true for all devices? It is not just DSA devices where
the hardware engineer is free to wire up the front panel however they
want, it can happen for any device.

In mlxsw, driver queries the FW to get this info.

There already are a lot of attributes, adding more doesn't necessarily
help make things clearer.

Why not address that problem. My concern is that your new attribute
will have the same problem.

Also adding pf and vfNNN on the name will make the already tightly squeezed
interface name length a real problem. I have had arguments with people
trying use VLAN 4000 and standard naming policy.  Which means you really
can't go that long.

Understood. However, I just do what is already done in nfp for example.

re "2 physical ports, 1 pf, and 4 vfs" --- does NFP exposes one PF for
both physical ports?

FWIW note that in mlx5 and AFAIK any other device except for mlx4 (...)
folks have FPP (Function Per Port) scheme.

What is the purpose/role in getting dev link ports here? is it such
that @ the end
of the day the driver would do a devlink_port_get_phys_port_name() call in their
get phys port name ndo? or we buy more advantages out of doing so?

Or.

Yes there are multiple PCIe PFs on the card, but the basic CX card just
uses one for all uplinks (like mlx4).

IMHO having way to get all netdevs and the netdev type from devlink is
quite user friendly.  As of today we also use the devlink ports for port
splitting on 40/100G parts.  Hopefully more functionality migrates over
from ethtool over time.
