The kernel fuzz handling is buggy, especially when we want to rely on the fuzz value for our hysteresis. But since this is a hw property and (at least sometimes) set by the driver, we can't make this a pure libinput hwdb set either. So our workaround is: * extract the (non-zero) fuzz into a udev property so we don't lose it * set the fuzz to 0 to disable the in-kernel hysteresis * overwrite our internal absinfo with the property fuzz This way we get to use the hw-specified fuzz without having the kernel muck around with it. We also get to use the EVDEV_ABS_ values in 60-evdev.hwdb to override a driver-set fuzz. Two drawbacks: - we're resetting the kernel fuzz to 0, this affects any other users of the device node. That's probably a minor impact only. - we can only save this in a udev property there's a risk of this information getting lost when playing around with udev rules. That too should be a minor issue. https://bugs.freedesktop.org/show_bug.cgi?id=105303 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> |
