Thanks Matt. That's on FreeBSD, I suppose? Would like to have this type
of service on x86 mini-PCs. :)

Hello Sulev-Madis,
What's your target platform ?
I recently discovered that GPIO interrupts are not supported in "GPIO
Bus" driver on x86 platforms because of lack of INTRNG support (simply
not implemented). I found a 6-year old diff D26407 from avg@ to add
this functionally which stuck on review because of some unsolved
issues. I renewed avg's patch so it could be applied to -current and
posted for review (D57968) again, but it did get much traction too.
So, if you are interested in getting GPIO interrupts on x86/amd64 - no
luck till gpiobus driver is "fixed". No ideas about arm and others.
Just as a reference point, I use the gpio interrupt support on rpi4
hosts to track things like water flow for feed systems in an
industrial farm environment. Seems to work quite well.
