I'm working on a touch panel device driver, which is built in VR41xx CPU.
I'd like to make it work as the wsmouse device. But it seems that the
wsmouse does not support a device which handles absolute corrdinates.
Is there any other touch panel or tablet device support on the NetBSD?
If no one is working about it, I propose that:
1. Add an argument to wsmouse_input(). The new argument is flag, which
indicate whether the cordinates are absulute or relative. If the
coordinates are absolute, the wsmouse_input produce an
WSCONS_EVENT_MOUSE_ABSOLUTE_X event instead of ..._DELTA_X.
(WSCONS_EVENT_MOUSE_ABSOLUTE_X is alredy defined in wsconsio.h.)
2. Define new mouse type WSMOUSE_TYPE_VRPIU or WSMOUSE_TYPE_TPANEL
(The former means VR41xx built-in touch panel controller, and the
latter means a general touch panel. Which is better?)
3. Introduce a new I/O controll command WSMOUSEIO_SPARAMS, with which we
can put sample coordinates retrieved with calibration.
WSMOUSEIO_GPARAMS is also needed.
