2015-01-29HID: wacom: add support for Cintiq 27QHD and 27QHD touchPing Cheng1-14/+73
These devices have accelerometers. To report accelerometer coordinates, a new property, INPUT_PROP_ACCELEROMETER, is added. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2015-01-29HID: wacom: make sure touch arbitration is applied consistentlyPing Cheng1-2/+4
stylus_in_proximity is used to make sure no touch event is sent while pen is in proximity. touch_down is used to make sure a touch up event is sent when pen comes into proximity while touch is down. Two touch routines didn't store touch_down. One touch routine forgot to check stylus_in_proximity before sending touch events. This patch fixes those issues.

2015-01-23HID: wacom: Report ABS_MISC event for Cintiq Companion HybridJason Gerecke1-0/+6
It appears that the Cintiq Companion Hybrid does not send an ABS_MISC event to userspace when any of its ExpressKeys are pressed. This is not strictly necessary now that the pad exists on its own device, but should be fixed for consistency's sake. Traditionally both the stylus and pad shared the same device node, and xf86-input-wacom would use ABS_MISC for disambiguation. Not sending this causes the Hybrid to behave incorrectly with xf86-input-wacom beginning with its 8f44f3 commit.

2015-01-12HID: wacom: peport In Range event according to the specPing Cheng1-7/+8
Some Cintiq and Intuos tablets report In Range event. This event is sent before valid data is reported when tool enters proximity; or before out of proximity event is reported when tool exits. While entering proximity, In Range means a pen is detected. This information can be used for palm/touch rejection on both pen and touch enabled devices. While exiting, it means the tool has reached its maximum detectable distance. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2015-01-12HID: wacom: process invalid Cintiq and Intuos data in wacom_intuos_inout()Ping Cheng1-24/+26
Users may use unsupported tools on Cintiq or Intuos. When invalid tools or data are detected, they should be ignored. That is, no event from those tools should be reported. Consolidating that code in wacom_intuos_inout simplifies the logic and make it easier for future code change. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2015-01-06HID: wacom: use WACOM_*_FIELD macros in wacom_usage_mapping()Benjamin Tissoires1-8/+0
We introduced nice macros in wacom_wac.c to check whether a field is a pen or a touch one. wacom_usage_mapping() still uses it's own tests, which are not in sync with the wacom_wac tests (.application is not checked). That means that some legitimate fields might be filtered out from the usage mapping, and thus will not be used properly while receiving the events.

2014-12-11HID: wacom: Report input events for each finger on generic devicesJason Gerecke1-28/+58
The existing generic touch code only reports events after reading an entire HID report, which practically means that only data about the last contact in a report will ever be provided to userspace. This patch uses a trick from hid-multitouch.c to discover what type of field is at the end of each contact; when such a field is encountered all the stored contact data will be reported.

2014-12-10HID: wacom: Initialize MT slots for generic devices at post_parse_hidJason Gerecke1-3/+0
If a HID descriptor places HID_DG_CONTACTID before HID_DG_X and HID_DG_Y then the ABS_X and ABS_Y will not be automatically initialized by the call to input_mt_init_slots. To ensure that this is not a problem, we relocate that call to occur after HID parsing has been completed and we've initalized all the multitouch axes.

2014-11-27HID: wacom: Consult the application usage when determining field typeJason Gerecke1-2/+4
It is not necessarily sufficient to look only at the physical and logical usages when determining if a field is for the pen or touch. Some fields are not contained in a sub-collection and thus only have an application usage. Not checking the application usage in such cases causes us to ignore the field entirely, which may lead to incorrect behavior.

2014-11-21HID: wacom: Add angular resolution data to some ABS axesJason Gerecke1-0/+10
Provide the resolution of several angular axes (tilt, pen rotation, puck rotation) to userspace. Because these values are natively degree-based, we need to convert them to into units/radian as required by the input_absinfo struct. To ensure wraparound behaves properly for the rotation axes, the converted value was rounded up rather than rounded nearest. Notably, the touchring axes (ABS_WHEEL and ABS_THROTTLE) are left without a a declared resolution because the their low resolution cannot be accurately represented (the worst-case rounding-induced error would be ~16 degrees). Pre-scaling the values and range by at least 10x would reduce the error in the resolution to acceptable levels, but the xf86-input-wacom driver is not able to use pre-scaled values for these axes at this time.

Centers the ABS_TILT_{X,Y} axes so that a value of zero is reported when the pen is vertical. Combined with resolution information in the next patch, this makes it possible for userspace to calculate the pen angle without needing hardware-specific knowledge. The xf86-input-wacom driver was updated to support signed tilt values in late-2012 (2f2acec).

2014-10-01HID: wacom: implement generic HID handling for pen generic devicesBenjamin Tissoires1-0/+179
ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2014-09-12HID: wacom: make the WL connection friendly for the desktopBenjamin Tissoires1-0/+3
Currently, tablets connected to the WL receiver all share the same VID/PID. There is no way for the user space to know which one is which besides parsing the name. We can force the PID to be set to the actual hardware. This way, the input device will have the correct PID which can be match in libwacom. With only this trick, the pad input does not inherit the ID_INPUT_TABLET udev property from its parent. We can force udev to accept it by declaring a BTN_STYLUS which is never used. This way, tablets connected through WL can be used from the user point of view in the same way they are used while connected through wire.
