[Linuxptp-users] tx_timestamp_timeout and i210

[Axel H. <aho...@gm...>]

Hi Richard et al,

on Ubuntu 14.04 with all updates and latest Intel i210 igb driver I
regularly get tx_timestamp_timeout error messages with the default timeout
of 1ms. I then changed to 5ms and since then I don't see any more errors.

Does anybody see similar problems? Might this be a problem of the PC (some
years old HP xw workstation) or might this be a i210 problem?

Any hint appreciated.

Regards
Axel

Hi,

Make sure you have disabled EEE support. If EEE is on, then the i210 device can take a very long time to return timestamps if the only traffic running is ptp. (since the link will go to sleep inbetween the frames).

That should be the issue here. If you still see the issue please let me know.

Regards,
Jake

[Axel H. <aho...@gm...>]

Hi Jake,

thanks for this rast reply.

I searched the web and finally did this:

sudo modprobe igb EEE=0

Does this suffice or how can I read the igb parameters?

Thanks a lot
Axel

Re: [Linuxptp-users] tx_timestamp_timeout and i210

[Keller, J. E <jac...@in...>]

Use ethtool.

$ethtool --set-eee <device>  off

Don't bother with module parameters. On modern kernels all the module parameters have other ways of configuring the same behavior.

Re: [Linuxptp-users] tx_timestamp_timeout and i210

[Axel H. <aho...@gm...>]

Got it. Thank you.

I modified /etc/network/interfaces and added the last line
ethtool --set-eee eth0 eee off

Now even after a reboot EEE is switched off on eth0.

Cheers
Axel

Re: [Linuxptp-users] tx_timestamp_timeout and i210

[Keller, J. E <jac...@in...>]

If the increase in the polling time is enough to fix this, then it's
likely just a delay that can be worked around. If you see drops above a
a few milliseconds (try setting poll timer to 100? Too long and ptp4l
will delay more significantly as it spins waiting.)

Jake

Re: [Linuxptp-users] tx_timestamp_timeout and i210

Hi Jake et al,

unfortunately the error message "timed out while polling for tx timestamp"
still occurs, even with EEE disabled (checked with "ethtool --show-eee
eth0".

Re: [Linuxptp-users] tx_timestamp_timeout and i210

[Axel H. <aho...@gm...>]

Hi Jake,

please forgive me my ignorance. With poll timer you mean tx_timestamp_retries, right? I always left it to its default 100.

With tx_timestamp_timeout set to 5 (milliseconds) I didn't observe the issue.

Cheers
Axel

Re: [Linuxptp-users] tx_timestamp_timeout and i210

[Keller, J. E <jac...@in...>]

Tx_timestamp_timeout value. If you set this to 5 it polls for up to 5 milliseconds instead of 1.

If that resolves your issue it's just a quirk of the particular hardware not being able to respond with a timestamp fast enough.

Jake
