It appears that the #Intel #I219V e1000e driver for #Linux now supports #IEEE #1588 #PTPv2 precision timing with hardware #timestamping on the #ThinkPad P14S. I'm still qualifying it against an #I226V based master clock on my #LAN across an #FS #S3900 (non-retiming, no boundary clock) in P2P mode. The master is hosted on #Proxmox 9.1, and has a PCIe serial card ready for a GPSDO. There is also a #SiRFStar IV based USB GPS for it to fix to #utc but sadly it doesn't emit# PPS pulses on DCD.
