Up until now, there was no way to let the user select the hardware
PTP provider at which time stamping occurs. The stack assumed that PHY time
stamping is always preferred, but some MAC/PHY combinations were buggy.
This series updates the default MAC/PHY default timestamping and aims to
allow the user to select the desired hwtstamp provider administratively.
Changes in v8:
- Drop the 6 first patch as they are now merged.
- Change the full implementation to not be based on the hwtstamp layer
(MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a
phc qualifier.
- Made some patch to prepare the new implementation.
- Expand netlink tsinfo instead of a new ts command for new hwtstamp
configuration uAPI and for dumping tsinfo of specific hwtstamp provider.
- Link to v7: https://lore.kernel.org/r/20231114-feature_ptp_netnext-v7-0-472e77951e40@bootlin.com
Changes in v7:
- Fix a temporary build error.
- Link to v6: https://lore.kernel.org/r/20231019-feature_ptp_netnext-v6-0-71affc27b0e5@bootlin.com
Changes in v6:
- Few fixes from the reviews.
- Replace the allowlist to default_timestamp flag to know which phy is
using old API behavior.
- Rename the timestamping layer enum values.
- Move to a simple enum instead of the mix between enum and bitfield.
- Update ts_info and ts-set in software timestamping case.
Changes in v5:
- Update to ndo_hwstamp_get/set. This bring several new patches.
- Add few patches to make the glue.
- Convert macb to ndo_hwstamp_get/set.
- Add netlink specs description of new ethtool commands.
- Removed netdev notifier.
- Split the patches that expose the timestamping to userspace to separate
the core and ethtool development.
- Add description of software timestamping.
- Convert PHYs hwtstamp callback to use kernel_hwtstamp_config.
Changes in v4:
- Move on to ethtool netlink instead of ioctl.
- Add a netdev notifier to allow packet trapping by the MAC in case of PHY
time stamping.
- Add a PHY whitelist to not break the old PHY default time-stamping
preference API.
Changes in v3:
- Expose the PTP choice to ethtool instead of sysfs.
You can test it with the ethtool source on branch feature_ptp of:
https://github.com/kmaincent/ethtool
- Added a devicetree binding to select the preferred timestamp.
Changes in v2:
- Move selected_timestamping_layer variable of the concerned patch.
- Use sysfs_streq instead of strmcmp.
- Use the PHY timestamp only if available.

Timestamping software or hardware flags are often used as a group,
therefore adding these masks will easier future use.
I did not use SOF_TIMESTAMPING_SYS_HARDWARE flag as it is deprecated and
not use at all.

Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.

---
Changes in v5:
- Extract the API change in this patch.
- Rename whitelist to allowlist.
- Set NETDEV_TIMESTAMPING in register_netdevice function.
- Add software timestamping case description in ts_info.
Change in v6:
- Replace the allowlist phy with a default_timestamp flag to know which
phy is using old API behavior.
- Fix dereferenced of a possible null pointer.
- Follow timestamping layer naming update.
- Update timestamp default set between MAC and software.
- Update ts_info returned in case of software timestamping.
Change in v8:
- Reform the implementation to use a simple phy_is_default_hwtstamp helper
instead of saving the hwtstamp in the net_device struct.

Prepare for future support of saving hwtstamp source in PTP xarray by
introducing HWTSTAMP_SOURCE_UNSPEC to hwtstamp_source enum, setting it
to 0 to match old behavior of no source defined.

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Move from simple ida to xarray for storing and loading the ptp_clock
pointer. This prepares support for future hardware timestamp selection by
being able to link the ptp clock index to its pointer.

Prepare for future hardware timestamp selection by adding source and
corresponding pointers to ptp_clock structure. Additionally, introduce
helpers for registering specific phydev or netdev PTP clocks, retrieving
PTP clock information such as hwtstamp source or phydev/netdev pointers,
and obtaining the ptp_clock structure from the phc index.

Introduce the description of a hwtstamp provider which is define with a
ptp_clock pointer and a qualifier value.
Add a hwtstamp provider description within the netdev structure to be able
to select the hwtstamp we want too use. By default we use the old API that
does not support hwtstamp selectability which mean the hwtstamp ptp_clock
pointer is unset.

The hardware registration clock for net device is now using
netdev_ptp_clock_register to save the net_device pointer within the PTP
clock xarray. netdevsim is registering its ptp through the mock driver.
It is the only driver using the mock driver to register a ptp clock.
Convert the mock driver to the new API.
Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>

Shouldn't we move the mock driver in the netdevsim directory as it is only
used by netdevsim driver?

Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a
network topology and read current hwtstamp configuration.
Introduce support for ETHTOOL_MSG_TSINFO_SET ethtool netlink socket to
configure hwtstamp of a PHC provider. Note that simultaneous hwtstamp
isn't supported; configuring a new one disables the previous setting.
Also, add support for a specific dump command to retrieve all hwtstamp
providers within the network topology, with added functionality for
filtered dump to target a single interface.

Pointer attached_dev is used to know if the phy is on the net topology.
This might not be enough and might need Maxime Chevallier link topology

Add new attributed to tsinfo allowing to get the tsinfo and the hwtstamp
from a phc provider (composed by a phc index and a phc qualifier) on a
netdevice's link.
Add simultaneously a set command to be able to set hwtstamp configuration
for a specified phc provider.

Overall, I agree with the motivation and reasoning behind the patch. It
takes dedicated effort to build a good phy timestamping mechanism, so
this approach is good. I do have a question though. In this patch if we
set the phy as the default timestamp mechanism, does that mean for even
non-PTP applications, the phy will be used for timestamping when
hardware timestamping is enabled? If so, I think this might need some
thought because there are timing applications in general when a
timestamp closest to the MAC layer would be best.

I might just be terrible at reading code, but isn't this what
tx_reserved in ethtool_ts_info is for? I feel like using one of the
reserved memspaces for this enum removes the need to make
kernel_ethtool_ts_info? I might be missing something obvious however.

This probably does not matter too much given that the mii_ts is not
visible until we fully probed the PHY, though for consistency and to be
on the safe side, it would be more prudent to set default_timestamp
before finishing the mii_ts assignment, in case we ever become more
aggressive at exposing objects to user-space/kernel-space. Probably over
thinking this.

Was not obvious that we could remove the phydev NULL check, but it's
fine because phy_is_default_hwtstamp() calls phy_has_hwtstamp() first,
and that function has that check. Seems a bit brittle, but fair enough.

This gets interesting. I think the reason it live under drivers/ptp
rather than drivers/net/netdevsim is because a bunch of reference/simple
phc implementations live under drivers/ptp already. In the case of mlx5,
it lives under the mlx5 driver directory to avoid needing to export
symbols between some mlx5_ptp driver and the netdev driver. I think
since the mock-up driver makes for a good reference for developers
wanting to know what it would take to implement the functionality for a
phc, it is fine living under drivers/ptp. That is just my opinion
though.

Could you give some examples? It seems odd to me, the application
wants a less accurate timestamp?
Is it more about overheads? A MAC timestamp might be less costly than
a PHY timestamp?
Or is the application not actually doing PTP, it does not care about
the time of the packet on the wire, but it is more about media access
control? Maybe the applications you are talking about are misusing the
PTP API for something its not intended?

It's a combination of both though I think primarily about line rate.
This point is somewhat carried over from the previous discussions on
this patch series in the last revision. I assume the device in question
here cannot timestamp at the PHY at a high rate.

So hardware timestamping is not a PTP specific API or application right?
It's purely a socket option that is not tied to PTP (unless I am missing
something here).
https://docs.kernel.org/networking/timestamping.html#timestamp-generation
So you could use this information for other applications like congestion
control where you do not want to limit the line rate using the PHY
timestamping mechanism.
In mlx5, we only steering PTP traffic to our PHY timestamping mechanism
through a traffic matching logic.
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/tree/drivers/net/ethernet/mellanox/mlx5/core/en/ptp.h?id=a6e0cb150c514efba4aaba4069927de43d80bb59#n71
This is because we do not want to PHY/port timestamp timing related
applications such as congestion control. I think it makes sense for
specialized timestamping applications to instead use the ethtool ioctl
to reconfigure using the PHY timestamps if the device is capable of PHY
timestamping. (So have the change be in userspace application tools like
linuxptp where precise but low <relative> rate timestamp information is
ideal).

Well, we have drivers/ptp. The IOCTL numbers are all PTP_XXXX. It
seems like the subsystem started life in order to support PTP. It is
not unusual for a subsystem to gain extra capabilities, and maybe PTP
timestamps can be used in a more general way than the PTP
protocol.

I think the key API point here is, you need to separate PTP stamping
from other sorts of stamping. PTP stamping generally works better at
the lowest point. So PTP stamping could be PHY stamping. If the PHY
does not support PTP, or its implementation is poor, PTP stamping can
be performed at the MAC. There are plenty of MACs which support that.
So we need an API to configure where PTP stamping is performed.
I expect the socket option is more generic. It is more about, give me
a time stamp at a specific point in the stack. It is probably not
being used by PTP, it could be used for flow control, etc. We probably
need an API to configure that SOF_TIMESTAMPING_RX_HARDWARE actually
means. It could be the PHY time stamp, maybe the MAC timestamp. Same
for SOF_TIMESTAMPING_TX_HARDWARE, it could be the MAC, could be the
PHY. But whatever they mean, i expect they are separate PTP.

I would expect linuxptp is only interested in the PTP timestamp. It
might be interested where the stamp is coming from, PHY or MAC, but it
probably does not care too much, it just assumes the time stamp is
good for PTP. But i would expect linuxptp has no interest in what the
generic socket options are doing.

I did it to prepare the introduction phc_qualifier in patch 12. I am not sure it
would be wise to put it under tx/rx_reserved field. IMHO create a new kernel
structure is cleaner for that than the hack of using one of the tx/rx_reserved
field.

This patch comes from a request from Russell due to incompatibility between MAC
and PHY timestamping when both were supported.
https://lore.kernel.org/netdev/Y%2F4DZIDm1d74MuFJ@shell.armlinux.org.uk/
His point was adding PTP support to a PHY driver would select timestamp from it
by default even if we had a better timestamp with the MAC which is often the
case. This is an unwanted behavior.
https://lore.kernel.org/netdev/Y%2F6Cxf6EAAg22GOL@shell.armlinux.org.uk/
In fact, with the new support of NDOs hwtstamp and the
dev_get/set_hwtstamp_phylib functions, alongside this series which make
timestamp selectable, changing the default timestamp may be not necessary
anymore.
Russell any thought about it?

My position remains: in the case of Marvell PP2 network driver with a
Marvell PHY, when we add PTP support for the Marvell PHYs (I have
patches for it for years) then we must _not_ regress the existing
setup where the PP2 timestamps are the default.

Yes, that's what I thought.
About the Marvell PHYs PTP support I have a few fixes on it, but we will
talk about it when this series gets merged.

No worries. I could also be off here. I am mostly using mlx5 for my
perspective here and I think Kory and Russell sent some feedback that
likely confirms that this patch makes sense. Will reply to that in a
bit.

This is a great point to bring up. I think the PTP related ioctls can be
confusing. Rather than calling them PTP ioctls, I think it would be best
to call them PHC ioctls, where PHC stands for PTP hardware clock. These
ioctls are more about controlling the local PTP clock devices rather
than handling timestamps sent/received via the PTP protocol.
https://docs.kernel.org/driver-api/ptp.html
We can look at the ptp4l source code and see that PTP does indeed depend
on the more generic PTP hardware timestamping socket options.
https://github.com/richardcochran/linuxptp/blob/f271257b799d390d9ec09d5c7dafb7f10a3bd99b/sk.c#L559
Again, I do know the ioctls can be confusing. The ioctls tend to be more
about adjusting the PHCs rather than controlling the timestamping flow
if that makes sense.

I actually agree with this to a degree. However, I do think it is
sensible for applications that understand their properties to explicitly
select the timestamping layer in the application initialization as well.
I think because of the impact on line rate, the MAC/DMA layer makes
sense as the default.

As I linked above, the socket options are being utilized by the linuxptp

For timestamping events and being able to generate and receive them for
the userspace perspective, there is no special interface just for ptp.
That said, maybe it makes sense versus having the userspace stack just
make use of the generic timestamping options. I am slightly against
doing something special for the ptp implementation since I do think it
is a typically timestamping application with different configuration
parameters (like which timestamping layer to select).

Thanks for providing the additional context. This was helpful. Btw, I
absolutely agree that all PHYs should not be defaulted to for
timestamping applications. At best, a driver implementer can select that
the PHY will primarily be used in timestamping applications that benefit
from it doing the timestamp work (which is what this patch does).

I agree 100% that the previous default of the PP2 (DMA) timestamps for
the Marvell PP2 network driver should not break from this work. We
similarly would not want the same in mlx5 in general (today the default
is DMA timestamping except for PTP traffic which we have selection rules
based on the packet). This patch is essentially to avoid all PHYs
starting to default to being the timestamping source which I agree with.
I guess Kory explicitly defaulted PHYs that were used primarily for PTP
applications/timestamping applications that primarily benefit from the
PHY timestamp. With this, I think it's safe to say that I agree with
this patch personally.
