[Bug 659126] [NEW] RFE: Way to calibrate /dev/input/eventX joysticks

[Dave Ahlswede]

Public bug reported:

As games on Linux increasingly transition to using /dev/input/eventX
devices instead of /dev/input/jsX devices (SDL uses event devices by
default now, and libois can only use event devices), users of older
joysticks are faced with the problem of not being able to calibrate them
--with newer ones, this tends not to be a problem, but with older
joysticks (in my case, a Gravis XTerminator Digital gamepad, which has
issues with center drifting and less-than-full range of motion
reporting), it can be critical.

There's one userspace alternative, evmapd (
http://users.softlab.ntua.gr/~thkala/projects/evmapd/evmapd.html ), but
it's limited in what it can do (imperfect auto-calibration only), and
leaves extraneous device nodes that some programs can't intelligently
deal with.


It would be extremely nice if there was a calibration/remapping API similar to what js devices support, that worked on event devices (and even better if both synchronized their data)
