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.

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).

HID: wacom: Ignore attempts to overwrite the touch_max value from HID The `wacom_feature_mapping` function is careful to only set the the touch_max value a single time, but this care does not extend to the `wacom_wac_finger_event` function. In particular, if a device sends multiple HID_DG_CONTACTMAX items in a single feature report, the driver will end up retaining the value of last item. The HID descriptor for the Cintiq Companion 2 does exactly this. It incorrectly sets a "Report Count" of 2, which will cause the driver to process two HID_DG_CONTACTCOUNT items. The first item has the actual count, while the second item should have been declared as a constant zero. The constant zero is the value the driver ends up using, however, since it is the last HID_DG_CONTACTCOUNT in the report. Report ID (16), Usage (Contact Count Maximum), ; Contact count maximum (55h, static value) Report Count (2), Logical Maximum (10), Feature (Variable), To address this, we add a check that the touch_max is not already set within the `wacom_wac_finger_event` function that processes the HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore the updated value. This could potentially cause problems if there is a tablet which has a similar issue but requires the last item to be used. This is unlikely, however, since it would have to have a different non-zero value for HID_DG_CONTACTMAX earlier in the same report, which makes no sense except in the case of a firmware bug. Note that cases where the HID_DG_CONTACTMAX items are in different reports is already handled (and similarly ignored) by `wacom_feature_mapping` as mentioned above.

Revert "HID: wacom: generic: read the number of expected touches on a per collection basis" This reverts commit 15893fa40109f5e7c67eeb8da62267d0fdf0be9d. The referenced commit broke pen and touch input for a variety of devices such as the Cintiq Pro 32. Affected devices may appear to work normally for a short amount of time, but eventually loose track of actual touch state and can leave touch arbitration enabled which prevents the pen from working. The commit is not itself required for any currently-available Bluetooth device, and so we revert it to correct the behavior of broken devices. This breakage occurs due to a mismatch between the order of collections and the order of usages on some devices. This commit tries to read the contact count before processing events, but will fail if the contact count does not occur prior to the first logical finger collection. This is the case for devices like the Cintiq Pro 32 which place the contact count at the very end of the report. Without the contact count set, touches will only be partially processed. The `wacom_wac_finger_slot` function will not open any slots since the number of contacts seen is greater than the expectation of 0, but we will still end up calling `input_mt_sync_frame` for each finger anyway. This can cause problems for userspace separate from the issue currently taking place in the kernel. Only once all of the individual finger collections have been processed do we finally get to the enclosing collection which contains the contact count. The value ends up being used for the *next* report, however. This delayed use of the contact count can cause the driver to loose track of the actual touch state and believe that there are contacts down when there aren't. This leaves touch arbitration enabled and prevents the pen from working. It can also cause userspace to incorrectly treat single- finger input as gestures.

HID: wacom: Fix sibling detection regression 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.

HID: wacom: Avoid entering wacom_wac_pen_report for pad / battery It has recently been reported that the "heartbeat" report from devices like the 2nd-gen Intuos Pro (PTH-460, PTH-660, PTH-860) or the 2nd-gen Bluetooth-enabled Intuos tablets (CTL-4100WL, CTL-6100WL) can cause the driver to send a spurious BTN_TOUCH=0 once per second in the middle of drawing. This can result in broken lines while drawing on Chrome OS. The source of the issue has been traced back to a change which modified the driver to only call `wacom_wac_pad_report()` once per report instead of once per collection. As part of this change, pad-handling code was removed from `wacom_wac_collection()` under the assumption that the `WACOM_PEN_FIELD` and `WACOM_TOUCH_FIELD` checks would not be satisfied when a pad or battery collection was being processed. To be clear, the macros `WACOM_PAD_FIELD` and `WACOM_PEN_FIELD` do not currently check exclusive conditions. In fact, most "pad" fields will also appear to be "pen" fields simply due to their presence inside of a Digitizer application collection. Because of this, the removal of the check from `wacom_wac_collection()` just causes pad / battery collections to instead trigger a call to `wacom_wac_pen_report()` instead. The pen report function in turn resets the tip switch state just prior to exiting, resulting in the observed BTN_TOUCH=0 symptom. To correct this, we restore a version of the `WACOM_PAD_FIELD` check in `wacom_wac_collection()` and return early. This effectively prevents pad / battery collections from being reported until the very end of the report as originally intended.

Input: wacom - create a separate input device for pads Currently, the pad events are sent through the stylus input device for the Intuos/Cintiqs, and through the touch input device for the Bamboos. To differentiate the buttons pressed on the pad from the ones pressed on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This lead to a multiplexing of the events into one device, which are then splitted out in xf86-input-wacom. Bamboos are not using MISC events because the pad is attached to the touch interface, and only BTN_TOUCH is used for the finger (and DOUBLE_TAP, etc...). However, the user space driver still splits out the pad from the touch interface in the same way it does for the pro line devices. The other problem we can see with this fact is that some of the Intuos and Cintiq have a wheel, and the effective range of the reported values is [0..71]. Unfortunately, the airbrush stylus also sends wheel events (there is a small wheel on it), but in the range [0..1023]. From the user space point of view it is kind of difficult to understand that because the wheel on the pad are quite common, while the airbrush tool is not. A solution to fix all of these problems is to split out the pad device from the stylus/touch. This decision makes more sense because the pad is not linked to the absolute position of the finger or pen, and usually, the events from the pad are filtered out by the compositor, which then convert them into actions or keyboard shortcuts. For backward compatibility with current xf86-input-wacom, the pad devices still present the ABS_X, ABS_Y and ABS_MISC events, but they can be completely ignored in the new implementation.

Input: wacom - create a separate input device for pads Currently, the pad events are sent through the stylus input device for the Intuos/Cintiqs, and through the touch input device for the Bamboos. To differentiate the buttons pressed on the pad from the ones pressed on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This lead to a multiplexing of the events into one device, which are then splitted out in xf86-input-wacom. Bamboos are not using MISC events because the pad is attached to the touch interface, and only BTN_TOUCH is used for the finger (and DOUBLE_TAP, etc...). However, the user space driver still splits out the pad from the touch interface in the same way it does for the pro line devices. The other problem we can see with this fact is that some of the Intuos and Cintiq have a wheel, and the effective range of the reported values is [0..71]. Unfortunately, the airbrush stylus also sends wheel events (there is a small wheel on it), but in the range [0..1023]. From the user space point of view it is kind of difficult to understand that because the wheel on the pad are quite common, while the airbrush tool is not.

HID: wacom: Fix sensor outbounds and redefine as offsets from each edge 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.

Input: wacom - create a separate input device for pads Currently, the pad events are sent through the stylus input device for the Intuos/Cintiqs, and through the touch input device for the Bamboos. To differentiate the buttons pressed on the pad from the ones pressed on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This lead to a multiplexing of the events into one device, which are then splitted out in xf86-input-wacom. Bamboos are not using MISC events because the pad is attached to the touch interface, and only BTN_TOUCH is used for the finger (and DOUBLE_TAP, etc...). However, the user space driver still splits out the pad from the touch interface in the same way it does for the pro line devices. The other problem we can see with this fact is that some of the Intuos and Cintiq have a wheel, and the effective range of the reported values is [0..71]. Unfortunately, the airbrush stylus also sends wheel events (there is a small wheel on it), but in the range [0..1023]. From the user space point of view it is kind of difficult to understand that because the wheel on the pad are quite common, while the airbrush tool is not. A solution to fix all of these problems is to split out the pad device from the stylus/touch. This decision makes more sense because the pad is not linked to the absolute position of the finger or pen, and usually, the events from the pad are filtered out by the compositor, which then convert them into actions or keyboard shortcuts. For backward compatibility with current xf86-input-wacom, the pad devices still present the ABS_X, ABS_Y and ABS_MISC events, but they can be completely ignored in the new implementation.

HID: wacom: Fix sensor outbounds and redefine as offsets from each edge 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.

HID: wacom: Fix sensor outbounds and redefine as offsets from each edge 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.

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.

HID: wacom: Fix sensor outbounds and redefine as offsets from each edge 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.

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.

HID: wacom: Fix sensor outbounds and redefine as offsets from each edge 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).
