Hi All,
I have a question regarding offset filters. I saw that there
are 2 type of filters for the delay that helps correcting it to.
Is there a reason not to do so also to offset?
Thank you

Well, the PI servo (or the linear regression servo) does "filter" the
inputs based on the weights. Also, take a look at the tsproc module.
If you can't find what you need
Thx Richard,
For some reason, I see spikes at clients, which are unreasonable. Most
of the time the offset is around +- 200ns, but from time to time it jumps to
more than 20 micro second.
This tells the client it needs to adjust its clock, but the adjustment
is not corr

You shouldn't have such spikes.

Hello,
Does LinuxPTP 1.6 implement Acceptable Master Table? If not, how does a PTP
slave select a master when there are multiple masters in the network? And I
would appreciate pointers to where in the code to look at for adding this
functionality if unavailable.
Thanks,
Daniel
