Guys: Is there any way for an input device driver (e.g. something that calls input_report_abs() and input_sync()) to know when there is a reader of its associated /dev/input/eventX? I would love to know when something calls evdev_read() and/or evdev_poll(), so that I could then initiate a sampling operation on the hardware itself. Otherwise, I'm forced to periodically poll the hardware and that means I'm either gathering data that no application wants, or I'm gathering it before (or faster than) an application is actually asking for it. I have stared at a lot of the evdev and related code, and can't find anything that looks like what I want. Am I just not seeing it, or am I looking in the wrong place?
