Hi, Im writing a driver for buttons permanently located on touchscreen surfaces outside of the main display area sutch as seen on most android devices designed for android <2.3 (google an image of a motorola atrix 4g for an example). This works by attaching to a input touchscreen device and sending a EV_KEY event if a touch lands on a button by matching simultaneous ABS_X ABS_Y and BTN_TOUCHSCREEN events to an arbitrarily defind map of rectangels with assigned keycodes, the WIP module can be examined here: https://github.com/IMbackK/droid4-linux/blob/virtual-buttons/drivers/input/misc/touchscreen-buttons.c I would also like to filter the events which land on a button, so that userspace dose not react to touch events on these buttons. However an input_handler filter handler is not sufficant for this purpose beacause i have no way of knowing if a touch event belongs to a defind button until the touchsreen driver has sent SYN_REPORT. I have tried to filter all events, while saving them and then reemmiting them by calling input_event() on the input_device of the touchscreen driver, this however crashes the ts driver. This also seams like a very hacky solution even if it where to work. 1. Is there some method to filter an entire sieries events enclosed by a SYN_REPORT? 2. Is there a good way to inject events to a input_device owned by another dirver? 3. Is there any other recommended method to satisfy the above requierments? -- Dev Null
