The latency from software responding to the timer and then firing an event
on a gpio would be eliminated.
No, the latency increases when using PHC. That is the whole point.
In the scenario I am describing, a hardware event is fired immediately
when the PHC timer expires in hardware. That ha

The kernel documentation states the ability to use POSIX timers with the PTP
hardware clocks. This does not appear to be implemented in the ptp
subsystem drivers. What is preventing this timer interface from being
implemented?
Previous discussions[1] indicate the PHC timer functionality was
