Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements.
Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to synchronize to reference frequency sources.
This patch series is a prerequisite for EEC object and adds ability to enable recovered clocks in the physical layer of the netdev object. Recovered clocks can be used as one of the reference signal by the EEC.
Further work is required to add the DPLL subsystem, link it to the netdev object and create API to read the EEC DPLL state.
You missed CCing Vadim. I guess Ccing the right people may be right up there with naming things as the hardest things in SW development..
Anyway, Vadim - do you have an ETA on the first chunk of the PLL work?
Sounds about right :) thanks for adding Vadim!
Good day Vadim,
Can we help on the new PLL interfaces? I can start some works related to that, although would need a guidance from the expert. Where to place it? What in-kernel interfaces to use? Any other high level tips that could be useful? Or if you already started some work, could you please share some information?
Hi!
I'm going to publish RFC till the end of the week and we will be able to continue discussion via this mailing list. I think that netlink is a good option for in-kernel interface and is easy to implement.
Oh, that sounds great! Thank you!
Good day Vadim,
Hope you are well! I have been trying to find a new RFC on mailing list, but could not find it. I guess, it was not submitted yet? Could you please share your current schedule for this task? Or maybe we could help somehow?
