PTP Offloading on Intel NIC 810

I am trying to enable PTP offloading on NIC but I need some guidance as the commands I find online doesn't work, I am trying to set one NIC as master.

 

I have used the command and got below output, but when i try ptp4l to enable PTP it uses the kernel by default and I am not able to find any option to change it to hardware 

 

 

Command: ethtool -T ens192

 

Time stamping parameters for ens192:
Capabilities:
hardware-transmit
software-transmit
hardware-receive
software-receive
software-system-clock
hardware-raw-clock
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes:
off
on
Hardware Receive Filter Modes:
none
all

Hi Faisal,


I believe you're using old beta drivers. Please try the latest drivers

https://www.intel.com/content/www/us/en/download/19630/intel-network-adapter-driver-for-e810-series-devices-under-linux.html

 

And also let us to run this command for us to get the NVM version info:

ethtool -i <device>

Hi Faisal,


The driver is the latest version, but the NVM is quite old. I would first suggest to update the NVM to latest (4.20).

Please use the latest ptp4l, at least 3.1.1, as that solved some problems for another customer recently.

 

Here are the commands for setting master and slave.

 

Master clock:

sudo ptp4l -i <device> -m –H

 

Slave clock:

sudo ptp4l -i <device> -m -H -s

 

Also here are links to related information:

• https://github.com/richardcochran/linuxptp/blob/master/phc2sys.8

• https://github.com/richardcochran/linuxptp/blob/master/ptp4l.8

• https://github.com/richardcochran/linuxptp/blob/master/ts2phc.8

• https://www.mankier.com/8/ts2phc

• https://www.mankier.com/8/ptp4l

• https://www.mankier.com/8/phc2sys 

 

We will be waiting for your response.

Hi Team,

 

Below solution worked

 

1. Edit Chrony.conf file to move from NTP to PTP and add reference to hardware clock (refclock PHC /dev/ptp0) in the config file then restart the chrony services. 

2. After that I followed above steps provided above to install linux PTP and use ptp4l

 

Master clock: sudo ptp4l -i <device> -m –H

Slave clock: sudo ptp4l -i <device> -m -H -s

 

Thanks,

Faisal.

Hi Team,

 

I have noticed that whenever I update the kernel to perform some PTP testing, after a while the kernel firmware rolls back to older version. I have noticed this all the time and had to update the kernel frequently.

 

Can you let me know if this is a known problem of you need any details from me to investigate.

 

Thanks,

Faisal
