[LinuxPPS] 5 May 16:00 - PPS: low level IRQ timestamps recording.

[Cirilo Bernardo]

That's excellent, Rodolfo.

That will really reduce the latency of the time stamping.  Is there
any way to know if the interrupt was from an assert or clear, or is
the spacing of the assert/clear large enough that it doesn't matter?
