But that new update only applies to valuator maps < 2, i.e. x/y only. Other valuators are now ignored and remain on 0 forever.

* Restore wheel emulation for absolute devicesPeter Hutterer2016-01-20
| | | | | | | | | | | | | | | Wheel emulation relies on oldVals, which stopped updating in 3dcf6f123c5. Since wheel emulation may filter the abs event, store the event before we do anything with it. If we really want the abs_event, abs_queued will be set to 1, otherwise the value will be ignored. And now that we know abs_value is always valied, we can copy its value into old_vals, so that wheel emulation can calculate the delta correctly. https://bugs.freedesktop.org/show_bug.cgi?id=93617 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
* Only map x and y to axes 0 and 1Peter Hutterer2015-11-13
| | | | | | | | | | | | | | | | The Logitech G600 has one device with all axes north of ABS_MISC. The current code assigns ABS_MISC as first axis to map to axis 0, i.e. x. On button press, one node sends the BTN_LEFT but the other node sends an ABS_MISC with a 1 0 value. ABS_MISC is mapped to axis 0, this moves the pointer to (0, y) on every button click. Avoid this by simply mapping any axis other than x/y to at least axis 3, and make sure we only override the MT 0/1 axes when we actually have MT axes. https://bugs.freedesktop.org/show_bug.cgi?id=92856 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Keith Packard <keithp@keithp.com>

* Move EVDEV_RELATIVE_MODE logic earlierÉric Brunet2014-12-17
| | | | | | | | | | | | | | | When in EVDEV_RELATIVE_MODE, after converting the absolute valuators, the code unsets pEvdev->abs_queued. This is wrong if there are some absolute valuators which are not positions, such as a pressure valuators, because events on these valuators would be lost. This patch fixes the problem by doing the absolute->relative translation early. This way, abs_queued is not set and then unset when receiving absolute valuators representing positions. Other absolute events now set abs_queued and will be processed. Signed-off-by: Éric Brunet <Eric.Brunet@lps.ens.fr> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
* Don't update old_vals when not in EVDEV_RELATIVE_MODEÉric Brunet2014-12-17
| | | | | | | | | | When not in EVDEV_RELATIVE_MODE, absolute position is stored in old_vals. This serves no purpose except that old_vals is ready when the device is switched to EVDEV_RELATIVE_MODE. It is however better to make the copy between old_vals and abs_vals at the time of the switch rather than all the time.

* Change the logic concerning EVDEV_RELATIVE_MODE and in_proximityÉric Brunet2014-12-17
| | | | | | | | | | | | | | When not in_proximity, we don't really trust data, even though a valuator sent just before a in_proximity event might actually be important. The present code for EVDEV_RELATIVE_MODE throws away all data if not in_proximity, which is a little bit too much. This patch allows for relative values to be calculated and old_vals to be updated even if not in_proximity, but will prevent evdev to sending (presumably) wrong information to the X server. But at least, old_vals will be correctly filled when the device comes into proximity again.

* If only IgnoreRelativeAxes is set, init like a normal relative devicePeter Hutterer2014-08-18
| | | | | | | | | | | | In the current code, if only IgnoreRelativeAxes is set, the code would go on and force absolute axes to initialize even if the relative axes were successfully initialized. Evdev gives precedence to relative axes anyway, initializing absolute axes if the relative axes failed. Thus, if we explicitely want relative axes but leave the abs axes as-is, proceed as normal.

* Fix axis initialization for devices with abs x/y and rel scrollwheelsPeter Hutterer2014-08-18
| | | | | | | | | | | | | | The Xen Virtual Pointer device has ABS_X, ABS_Y and REL_WHEEL. If smooth scrolling is detected, the current code would first initialize relative axes for scrolling and immediately overwrite those axes when the abs valuators are written out. This patch fixes the default case only, in the case of a device setting the two Ignore*Axis options both to "off", the axes are still overwritten. The wheels will work, other axes only if the same number of abs axes exists. And it keeps the current memory leak too, but it's marked with a FIXME now.

* Make the slot-state per slotPeter Hutterer2014-08-18
| | | | | | | | | | | | | | | | | The previous approach only had the slot state for the current slot. If we changed slots, that means we lost the information if the slot was ever initialized. If the ABS_MT_TRACKING_ID was never received, the slot would still update and try to send events (which the server refused with a warning). Avoid this by having a per-slot state and a dirty bit that tells us if the current slot updated at all. If we don't get the tracking ID, leave the slot empty and refuse any further events from that touch. This quashes the various "unable to find touch point 0" warnings caused if a touchpoint starts before the device is enabled.

* Use the server's device list for duplicate detection (#78309)Peter Hutterer2014-05-07
| | | | | | | | | | | | | | | | | | | EvdevAddDevice/EvdevRemoveDevice keep a reference to the device to detect duplicate devices based on the dev_t. EvdevAddDevices was called during PreInit, EvdevRemoveDevice was called during DEVICE_CLOSE. That makes it imbalanced if the device succeeds PreInit but the server skips everything else because MAX_DEVICES is exceeded. So for all devices after MAX_DEVICES, we'd add a reference but never remove it, eventually reading/writing past evdev_devices. The server keeps the list of devices for us anyway, so remove the copy of all the pointers and instead run through the device list the server gives us.
