| D | sysfs-timecard | 17 Description: (RO) The list of available time sources that the PHC
58 PHC output PPS is from the PHC clock
62 IRIG output is from the PHC, in IRIG-B format
63 DCF output is from the PHC, in DCF format
76 the PHC. May be changed by writing one of the listed
246 Description: (RW) When retrieving the PHC with the PTP SYS_OFFSET_EXTENDED
247 ioctl, a system timestamp is made before and after the PHC
250 with the PHC time. This estimate may be wrong, as it depends
251 on PCI latencies, and when the PHC time was latched
255 retrieved PHC time.

| D | timestamping.rst | 597 There are situations when there may be more than one PHC (PTP Hardware Clock)
599 user to select which PHC to use for timestamping Ethernet frames. Instead, the
600 assumption is that the outermost PHC is always the most preferable, and that
622 I/O, they do have their own PHC). It is typical, but not mandatory, for all
623 interfaces of a DSA switch to share the same PHC.
743 But a MAC driver that is unaware of PHC stacking might get tripped up by
754 described above, in the case of a stacked PHC system, this condition should
755 never trigger, as this MAC is certainly not the outermost PHC. But this is
762 PHC system, this is incorrect because this MAC driver is not the only entity
770 that PTP timestamping is not enabled for anything other than the outermost PHC,
