    GPIO setup on x86

    Howdy, I am wanting to learn GPIO's on FreeBSD and I need advice on hardware. I have 3 platforms that have advertised GPIO's for I/O use. MinnowboardMax Turbot, Advantech PCM9362 and Nexcom VTC1000. None seem to have a working GPIO found. I have searched the forum here and looked at the docs...

    GPIO Interrupts handling (ARM)

    How to handle GPIO interrupts on BeagleBoard, Raspberry Pi etc. from the user space? That's under TODO at: https://wiki.freebsd.org/FreeBSD/GPIO although the page was edited 1.5 years ago.
