[Linuxptp-devel] [PATCH RFC 0/6] calculate PI constants for different sync intervals

[Richard Cochran]

Here is what I came up with after the recent discussion about adapting
the servo to the sync interval. I gave this some light testing,
including changing the sync on the fly. Comments are welcome.

Thanks,
Richard

Richard Cochran (6):
Use a consistent frequency estimation interval in the PI controller.
Let the clock servo know the expected sync interval.
Add a table of PI constants, with one entry per sync interval.
Provide a method to install a user constant into the table.
Add a configuration option for changing the table of PI constants.
Remove the legacy PI constant configuration options.
