2018-01-23HID: wacom: Fix reporting of touch toggle (WACOM_HID_WD_MUTE_DEVICE) eventsJason Gerecke1-8/+8
Touch toggle softkeys send a '1' while pressed and a '0' while released, requring the kernel to keep track of wether touch should be enabled or disabled. The code does not handle the state transitions properly, however. If the key is pressed repeatedly, the following four states of states are cycled through (assuming touch starts out enabled): Press: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Release: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Press: shared->is_touch_on => 1, SW_MUTE_DEVICE => 0 Release: shared->is_touch_on => 1, SW_MUTE_DEVICE => 1 The hardware always properly enables/disables touch when the key is pressed but applications that listen for SW_MUTE_DEVICE events to provide feedback about the state will only ever show touch as being enabled while the key is held, and only every-other time. This sequence occurs because the fallthrough WACOM_HID_WD_TOUCHONOFF case is always handled, and it uses the value of the *local* is_touch_on variable as the value to report to userspace. The local value is equal to the shared value when the button is pressed, but equal to zero when the button is released. Reporting the shared value to userspace fixes this problem, but the fallthrough case needs to update the shared value in an incompatible way (which is why the local variable was introduced in the first place). To work around this, we just handle both cases in a single block of code and update the shared variable as appropriate.

2017-11-21HID: wacom: Queue events with missing type/serial data for later processingJason Gerecke1-0/+1
Userspace expects to receive tool type and serial number information for the active pen in the very first kernel report, if such data is supported by the hardware. While this expectation is not an issue for EMR devices, AES sensors will often send several packets worth of in- range data before relaying type/serial data to the kernel. Sending this data "late" can result in proximity-tracking issues by xf86-input-wacom, or an inability to distinguish different pens by input-wacom. Options for dealing with this situation include ignoring reports from the tablet until we get the necessary data, or using the information from the last-seen pen instead of the (eventual) real data. Neither option is particularly attractive: the former results in truncated strokes and the latter causes issues with switching between pens. This commit instead opts to queue up events with missing information until we receive a report which contains it. At that point, we can update the driver's state variables (id[0] and serial[0]) and replay the queued events.

2017-11-21HID: wacom: Properly handle AES serial number and tool typeJason Gerecke1-9/+33
Current AES sensors relay tool type and serial number information with a different set of usages than those prescribed by the modern (i.e. MobileStudio Pro and newer) EMR tablet standard. To ensure the driver properly understands these usages, we modify them to be compatible. The identifying information is split across three consecutive fields: a 16-bit WACOM_HID_WT_SERIALNUMBER (which is more accurately described as WACOM_HID_WD_TOOLTYPE), a 32-bit HID_DG_TOOLSERIALNUMBER, and an 8-bit 0xFF000000 (which should be WACOM_HID_WD_SERIALHI). While we're at it, we also define proper min/max values since may may be undefined on some devices.

2017-11-09HID: wacom: generic: Send BTN_STYLUS3 when both barrel switches are setJason Gerecke1-2/+16
The Wacom Pro Pen 3D includes a third barrel switch which is intended to be particularly useful in applications where one frequency uses pan, zoom, and rotate to navigate around a scene or model. The pen is compatible with the MobileStudio Pro, 2nd-gen Intuos Pro, and Cintiq Pro. When the third button is pressed, these devices set both the HID_DG_BARRELSWITCH and HID_DG_BARRELSWITCH2 usages since their HID descriptors do not include a usage specific to the button. Rather than send both BTN_STYLUS and BTN_STYLUS2 when the third button is pressed, userspace (libinput) has requested that we detect this condition and report a newly-defined BTN_STYLUS3 event instead. We could define a quirk specific to devices compatible with the Pro Pen 3D, but the liklihood of seeing both barrel switch bits set with other pens/devices is low enough to not worry about (pens mechanically prevent accidental activation of multiple switches).

2017-10-11Revert "HID: wacom: generic: Send BTN_TOOL_PEN in prox once the pen enters ↵Jason Gerecke1-11/+0
range" This reverts commit 3e70969e44ee52d72053145dab2cbad74109c685. This commit causes a few problems for userspace. The most noteworthy are problems related to the distinguishing of different pens and pointer jumps when entering proximity. Userspace is written with the expectation that a pen will provide its tool ID and serial number (if available) in the very first in-prox report. By sending BTN_TOOL_PEN when the tablet starts communicating rather than waiting until a tool ID/serial number is available, userspace ends up treating all pens as being the same and lacking a serial number. Similarly, userspace assumes that the first report will contain X/Y data, but by marking the pen as being in-prox without an X/Y coordinate, userspace ends up warping the pen to the last- known X/Y location. As of commit 5b40104edfb0 ("HID: wacom: generic: Reset events back to zero when pen leaves") this means warping to (0,0).

When a pen is first able to to be sensed by the tablet, we would like to inform userspace that a tool is nearby so that it can attempt to perform palm rejection. Unfortunately, we don't know any information about the tool that is nearby, so the best we can do is send a prox event for a generic BTN_TOOL_PEN. If the pen later comes closer and enters proximity, we can determine the actual tool type and send BTN_TOOL_PEN out of prox if necessary.

2017-09-13HID: wacom: generic: Leave tool in prox until it completely leaves senseJason Gerecke1-5/+5
The legacy Intuos codepath and tablet behavior (e.g. the 1st-gen Intuos Pro, Cintiq 27, etc.) would result in a BTN_TOOL_* event not being cleared to zero until the tool had completely left the sensing range of the tablet. Before the final "out of prox" packet would be sent, zero or more "in range" packets could be sent to indicate that a pen was still detectable but not within a useful distance. These "in range" packets were used by the driver to keep touch input disabled at greater pen distances. In addition to keeping the `stylus_in_proximity` flag set, the driver would leave the current BTN_TOOL_* marked as being in proximity as well. The new HID codepath also sets `stylus_in_proximity` based on the "sense" flag, but does not leave the current BTN_TOOL_* marked as being in prox. This information is potentially useful to for a future userspace-based palm rejection, so this patch modifies the driver to continue sending it.

The tool ID information sent in ABS_MISC is expected to be reset to 0 when a tool leaves proximity. Not doing this can cause problems if a tool is removed and then re-introduced. Kernel event filtering will prevent the (identical) ABS_MISC event from being sent when the tool re-enters proxmity. This can cause userspace to not properly set the tool ID.

2017-09-13HID: wacom: generic: Send MSC_SERIAL and ABS_MISC when leaving proxJason Gerecke1-11/+16
The latest generation of pro devices (MobileStudio Pro, 2nd-gen Intuos Pro, Cintiq Pro) send a serial number of '0' whenever the pen is too far away for reliable communication. Userspace defines that a serial number of '0' is invalid, so we need to be careful not to actually forward this value. Additionally, since EMR ISDv4 devices do not support serial numbers or tool IDs, we'd like to not send these events if they aren't necessary. The existing code achieves these goals by adding a check for a non-zero serial number within the wacom_wac_pen_report function. The MSC_SERIAL and ABS_MISC events are only sent if the serial number is non-zero. This code fails, however when the pen for a pro device leaves proximity. When the pen leaves prox and the tablet sends a serial of 0, wacom_wac_pen_event dutifully clears the serial number. When wacom_wac_pen_report is called, it does not send either the MSC_SERIAL of the exiting tool nor an ABS_MISC event. This patch prevents the wacom_wac_pen_event function from clearing an already-set serial number. This ensures that we have the serial number handy when exiting proximity, but requires us to manually clear it afterwards to ensure the driver does not send stale data (e.g. when switching between AES pens that report a serial nubmer of 0 for the first few fully in-proximity packets).

2017-09-06HID: wacom: Correct coordinate system of touchring and pen twistJason Gerecke1-5/+68
The MobileStudio Pro, Cintiq Pro, and 2nd-gen Intuos Pro devices use a different coordinate system for their touchring and pen twist than prior devices. Prior devices had zero aligned to the tablet's left and would increase clockwise. Userspace expects data from the kernel to be in this old coordinate space, so adjustments are necessary. While the coordinate system for pen twist is formally defined by the HID standard, no such definition existed for the touchring at the time these tablets were introduced. Future tablets are expected to report touchring data using the same "zero-up clockwise-increasing" coordinate system defined for twist.

The WACOM_HID_WD_TOUCHRINGSTATUS usage is a single bit which tells us whether the touchring is currently in use or not. Because we need to reset the axis value to 0 when the finger is removed, we call 'wacom_map_usage' to ensure that the required type/code values are associated with the usage. The 'wacom_map_usage' also sets up the axis range and resolution, however, which is not desired in this particular case. Although xf86-input-wacom doesn't do really do anything with the ring's range or resolution, the libinput driver (for Wayland environments) uses these values to provide proper angle indications to userspace.

2017-05-05HID: wacom: generic: Refactor generic battery handlingJason Gerecke1-71/+91
Generic battery handling code is spread between the pen and pad codepaths since battery usages may appear in reports for either. This makes it difficult to concisely see the logic involved. Since battery data is not treated like other data (i.e., we report it through the power_supply subsystem rather than through the input subsystem), it makes reasonable sense to split the functionality out into its own functions. This commit has the generic battery handling duplicate the same pattern that is used by the pen, pad, and touch interfaces. A "mapping" function is provided to set up the battery, an "event" function is provided to update the battery data, and a "report" function is provided to notify the power_supply subsystem after all the data has been read. We look at the usage itself rather than its collection to determine if one of the battery functions should handle it. Additionally, we unconditionally call the "report" function since there is no particularly good way to know if a report contained a battery usage; 'wacom_notify_battery()' will filter out any duplicate updates, however.

This commit adds the ability to provide it with explict state information if desired.

2017-04-20HID: wacom: Override incorrect logical maximum contact identifierJason Gerecke1-0/+10
It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue 8 Pro 5855, etc.) suffer from a common issue in their HID descriptors. The logical maximum is not updated for the "Contact Identifier" usage, leaving it as just "1" despite these devices being capable of tracking far more touches. Commit 60a221869803 began ignoring usages with out-of-range values, causing problems for devices based on this chipset. Touches after the first will have an out-of-range Contact Identifier, and ignoring that usage will cause the kernel to incorrectly slot each finger's events (along with all the knock-on userspace effects that entails). This commit checks for these buggy descriptors and updates the maximum where required. Prior chipsets have used "255" as the maximum (and the G11, at least, doesn't seem to actually use IDs outside the range of 1..CONTACTMAX) so continue using this value.

2017-04-19HID: wacom: Treat HID_DG_TOOLSERIALNUMBER as unsignedJason Gerecke1-1/+1
Because HID_DG_TOOLSERIALNUMBER doesn't first cast the value recieved from HID to an unsigned type, sign-extension rules can cause the value of wacom_wac->serial[0] to inadvertently wind up with all 32 of its highest bits set if the highest bit of "value" was set. This can cause problems for Tablet PC devices which use AES sensors and the xf86-input-wacom userspace driver. It is not uncommon for AES sensors to send a serial number of '0' while the pen is entering or leaving proximity. The xf86-input-wacom driver ignores events with a serial number of '0' since it cannot match them up to an in-use tool. To ensure the xf86-input-wacom driver does not ignore the final out-of-proximity event, the kernel does not send MSC_SERIAL events when the value of wacom_wac->serial[0] is '0'. If the highest bit of HID_DG_TOOLSERIALNUMBER is set by an in-prox pen which later leaves proximity and sends a '0' for HID_DG_TOOLSERIALNUMBER, then only the lowest 32 bits of wacom_wac->serial[0] are actually cleared, causing the kernel to send an MSC_SERIAL event. Since the 'input_event' function takes an 'int' as argument, only those lowest (now-cleared) 32 bits of wacom_wac->serial[0] are sent to userspace, causing xf86-input-wacom to ignore the event. If the event was the final out-of-prox event, then xf86-input-wacom may remain in a state where it believes the pen is in proximity and refuses to allow other devices under its control (e.g. the touchscreen) to move the cursor. It should be noted that EMR devices and devices which use both the HID_DG_TOOLSERIALNUMBER and WACOM_HID_WD_SERIALHI usages (in that order) would be immune to this issue. It appears only AES devices are affected.

Wacom Cintiq Pro has a softkey to turn touch on/off. Since it is a softkey, hardware/firmware still reports touch events no matter what state the softkey is.

2017-02-14HID: wacom: Bluetooth IRQ for Intuos Pro should handle prox/rangeJason Gerecke1-10/+15
The prox/range bits included in the Bluetooth reports from the Intuos Pro were being ignored, leading to two issues. Firstly, the pen would never announce a BTN_TOOL_PEN event with value 0, leaving userspace to believe the pen was always active. Secondly, the driver would continue to send events for data while the packet's "prox" bit was clear. This can lead to sudden incorrect pointer jumps if the pen is slowly moved away from the tablet surface.

2017-02-03HID: wacom: don't apply generic settings to old devicesPing Cheng1-2/+3
Non-generic devices have numbered_buttons set for both pen and touch interfaces by default. The actual number of buttons on the interface is normally manually decided later, which is different from what those HID generic devices are processed, where number of buttons are directly retrieved from HID descriptors. This patch adds the missed HID_GENERIC check and moves the statement to wacom_setup_pad_input_capabilities since it's not a quirk anymore.

2017-01-26HID: wacom: Fix poor prox handling in 'wacom_pl_irq'Jason Gerecke1-13/+15
Commit 025bcc1 performed cleanup work on the 'wacom_pl_irq' function, making it follow the standards used in the rest of the codebase. The change unintiontionally allowed the function to send input events from reports that are not marked as being in prox. This can cause problems as the report values for X, Y, etc. are not guaranteed to be correct. In particular, occasionally the tablet will send a report with these values set to zero. If such a report is received it can caus an unexpected jump in the XY position. This patch surrounds more of the processing code with a proximity check, preventing these zeroed reports from overwriting the current state. To be safe, only the tool type and ABS_MISC events should be reported when the pen is marked as being out of prox.

2017-01-26HID: wacom: Support 2nd-gen Intuos Pro's Bluetooth classic interfaceJason Gerecke1-0/+197
In addition to its USB interface, the second-generation Intuos Pro includes a Bluetooth radio that offers two pairing interfaces: classic and low-energy. The classic interface functions just like the earlier Bluetooth-enabled Intuos4 and Graphire4 tablets, appearing as a HID device that our driver can work with. The low-energy interface is intented to be used by userspace applications that make use of its paper-to-digital capabilities. Despite the USB interface using Wacom's new vendor-defined HID usages, the Bluetooth interface provides us with useless black-box "blob" report descriptors like past devices. We thus have to explicitly add support for the PIDs and reports used. These devices pack a /lot/ of information into a single Bluetooth input report. Each report contains up to seven snapshots of the pen state, four snapshots of the touch state (of five touches each), pad state, and battery data. Thankfully this isn't too hard for the driver to report -- it just takes a fair amount of code to extract!

2017-01-19HID: wacom: Fix sibling detection regressionJason Gerecke1-0/+10
Commit 345857b ("HID: wacom: generic: Add support for sensor offsets") included a change to the operation and location of the call to 'wacom_add_shared_data' in 'wacom_parse_and_register'. The modifications included moving it higher up so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This was done to prevent a crash that would have occured when the report containing tablet offsets was fed into the driver with 'wacom_hid_report_raw_event' (specifically: the various 'wacom_wac_*_report' functions were written with the assumption that they would only be called once tablet setup had completed; 'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet allocated). Moving the call to 'wacom_add_shared_data' effectively prevented the crash but also broke the sibiling detection code which assumes that the HID descriptor has been read and the various device_type flags set. To fix this situation, we restore the original 'wacom_add_shared_data' operation and location and instead implement an alternative change that can also prevent the crash. Specifically, we notice that the report functions mentioned above expect to be called only for input reports. By adding a check, we can prevent feature reports (such as the offset report) from causing trouble.
