Hi Gwendal,
Despite the silence I haven't yet forgotten about this. I'm working on
an update to the Counter subsystem code that should help develop a
real time timestamp functionality for counter drivers. It's not yet
complete right now, but I'm hoping to release it later this month. I'll
CC you when the time comes to keep you updated and make sure it fits for
use cases. :-)
I'll review your current EC patch for a counter driver in the coming
days -- I have some IRL work I'm taking care of this week but I should
be able to take a look this weekend or soon after.
Thanks,
William Breathitt Gray
