Hello,

I'd just like to confirm something before possibly embarking on writing a custom PHC driver... (apologies if this has been asked before, I did scan the archives, but may have missed it)

Is it possible to do PTP on multiple domains, at the same time, using ptp4l?

I assume I'd run a separate instance for each domain, both using the same interface, and explicitly tell each instance which PHC to synchronise to/from?


So as long as I have enough PHC's exposed in user space (/dev/ptpN), I can happily run as many ptp domains over the same interface as I'd like? And phc2sys can happily synchronise any of these with any linux clocks (e.g. CLOCK_REALTIME?), or even with each other?


Thanks very much,

JP
