2017-11-21HID: wacom: Queue events with missing type/serial data for later processingJason Gerecke1-0/+3
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 Gerecke1-0/+3
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 Gerecke1-0/+2
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).

2017-10-19HID: wacom: generic: Recognize WACOM_HID_WD_PEN as a type of pen collectionJason Gerecke1-0/+1
The WACOM_PEN_FIELD macro is used to determine if a given HID field should be associated with pen input. This field includes several known collection types that Wacom pen data is contained in, but the WACOM_HID_WD_PEN application collection type is notably missing. This can result in fields within this kind of collection being completely ignored by the `wacom_usage_mapping` function, preventing the later '*_event' functions from being notified about changes to their value.

2017-05-05HID: wacom: generic: Refactor generic battery handlingJason Gerecke1-0/+4
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.

2017-05-05HID: wacom: Add ability to provide explicit battery status infoJason Gerecke1-0/+3
At the moment, our driver relies on 'wacom_battery_get_property()' to determine the most likely battery state (e.g charging, discharging, or full) based on the information available. It is not always possible for the function to properly determine this, however. For instance, whenever an AES pen leaves proximity the battery state becomes indeterminite. This commit adds the ability to provide it with explict state information if desired. Whenever explicit state is not required (the majority of circumstances), WACOM_POWER_SUPPLY_STATUS_AUTO can be used in its place. Three uses of explicit battery status are added: two wireless disconnect paths and the AES case mentioned above.

2017-01-26HID: wacom: Support 2nd-gen Intuos Pro's Bluetooth classic interfaceJason Gerecke1-2/+4
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!

2016-10-20HID: wacom: Fix sensor outbounds and redefine as offsets from each edgeJason Gerecke1-2/+4
Many of Wacom's display tablets include an "outbound" area where pen digitizing is possible but outside of the display area. To ensure that pen coordinates are mapped to the correct on-screen location, the driver sets the minimum and maximum axis values of X and Y to those coordinates which coincide with the screen edge. These values are simply the hardware minimum/maximum plus/minus the outbound size for a particular edge. When outbound support was added/updated in ac414da, fa77034, and ecd618d, we decided to have the wacom_features structs store the desired minimum and maximum values directly. In hindsight, this was perhaps not the best choice since it has allowed minor errors to crop up unnoticed. Some tablets have had their coordinates over-corrected (e.g. most of the devices "fixed" in ecd618d were already adjusted in ac414da), while others never had a correction applied (e.g. the ISDv5 325, whose declared maximum the hardware maximum instead of the outbound maximum). A less error-prone method of handling the outbound is to let the driver calculate the correct minimum/maximum values by providing it with both the actual hardware maximums and the size of the outbound on each edge. These values are more easy to verify as correct since the values can be trivially compared against specifications. This patch reverts the declared maximum values to the actual hardware maximums, e.g. as declared prior to ac414da (values for these and other display tablets that were subsuquently introduced have been verified against specs). Per-edge outbound sizes are stored in the wacom_features struct as offset_{left,right,top,bottom} and used in combination with the hardware ranges to calculate effective axis ranges for ABS_X and ABS_Y.

2016-10-20HID: wacom: generic: Add support for vendor-defined "Sense" usageJason Gerecke1-0/+3
Wacom's professional tablets beginning with the Intuos4 are capable of reporting an intermediate degree of proximity where the pen is no longer close enough to communicate with ("in prox"), but still close enough to be sensed ("in range"). This additional state is particularly useful for performing palm rejection as it allows the driver to disable the touch sensor while the pen is a greater distance from the tablet. Like other professional tablets, the new MobileStudio Pro also reports this intermeidate "in range" proximity state. Its descriptor assigns usage 0xff0d0036 to this bit. Normally 'wacom_equivalent_usage' would translate this to the standard HID "Quality" usage, but since this has a different meaning we have it explicitly ignore the usage and define it ourselves as "Sense" (since "In Range" is already defined by the HID standard and interpreted by our driver as meaning "in prox").

Wacom's new "MobileStudio Pro" tablets are the first devices in their branded product line-up to include a usable HID descriptor for the pen interface. Like prior branded products, the device can operate in one of two modes: 'Standard HID', and 'Wacom Custom HID'. Although the first mode is usable by the HID_GENERIC codepath as-is (huzzah!), it is subject to some restrictions -- most notably pressure being limited to 2048 levels instead of 8192. To ensure tablets that include support for Custom HID mode work optimally, we add support for its usages and switch the device to Custom HID mode if possible. The usages defined for Custom HID mode are often numerically similar to their standard HID equivalents, allowing us to write a simple translation function that takes arbitrary HID usages as input and which returns the corresponding standard HID usage as output (if one exists). Switching on this translated usage instead of the actual usage allows the existing cases to apply to both modes of operation without having to explicitly define every Custom HID usage.

2015-12-02HID: wacom: Rename wacom ID report ID macrosJason Gerecke1-2/+2
"INTUOSREAD" and "INTUOSWRITE" are poorly named. These are report IDs for pen ID (proximity) packets. It should be noted that the latter is only used on Intuos/Intuos2 for a second stylus when DualTrack is in use.

2015-11-02HID: wacom: fix Intuos wireless report id issuePing Cheng1-1/+1
Intuos Pen in wireless mode does not have the same report id (2) as when it is in USB mode (17). This patch also moves WIRELESS next to REMOTE in type enum so we can group devices with similar features easily.

2015-10-21HID: wacom: Tie cached HID_DG_CONTACTCOUNT indices to report IDJason Gerecke1-0/+1
The cached indicies 'cc_index' and 'cc_value_index' introduced in 1b5d514 are only valid for a single report ID. If a touchscreen has multiple reports with a HID_DG_CONTACTCOUNT usage, its possible that the values will not be correct for the report we're handling, resulting in an incorrect value for 'num_expected'. This has been observed with the Cintiq Companion 2. To address this, we store the ID of the report those indicies are valid for in a new 'cc_report' variable. Before using them to get the expected contact count, we first check if the ID of the report we're processing matches 'cc_report'. If it doesn't, we update the indicies to point to the HID_DG_CONTACTCOUNT usage of the current report (if it has one).

Adds support for the EMR (pen+pad) and touchscreen devices used by the Wacom Cintiq Companion 2. This applies both to using the device as a standalone system, as well as when operating in "Cintiq mode" (where the EMR/touchscreen are simply exposed as USB devices to the system its connected to).

Prior to this commit, numbered button bit setting was done separately for each device type in wacom_setup_pad_capabilities(). Here we add a numbered_buttons property to the wacom_features struct and extract the repeated bit setting code to a new function: wacom_settup_numbered_buttons().
