HID: multitouch: add support for trackpads * some multitouch trackpads present the touch usage. This needs to be filtered as it will conflict with mt-implementation. * trackpads send BTN_TOOL_* to notify how many fingers are present (this is used by xorg to use synaptics instead of generic evdev) * trackpads like Perixx 701 are not different from a hid point of view from a touchscreen, and we need to manually set them as touchpad.

HID: merge hid-egalax into hid-multitouch This patch merges the hid-egalax driver into hid-multitouch. There are two types of devices support by the hid-egalax driver: resistive and capacitive. Here, they are implicitly distinguished by the absence of a HID_DG_CONTACTCOUNT field in the latter, so no special code path needs to be introduced. As a side effect, this patch fixes the broken suspend/resume behavior in the old driver.

HID: hid-multitouch: migrate 3M PCT touch screens to hid-multitouch This patch merges the hid-3m-pct driver into hid-multitouch. To keep devices working the same way they used to with hid-3m-pct, we need to add two signal/noise ratios for width and height. We also need to work on width/height to send proper ABS_MT_ORIENTATION flag. Importing 3M into hid-multitouch also solved the bug in which devices handling width and height in their report descriptors did not show ABS_MT_TOUCH_MAJOR and ABS_MT_TOUCH_MINOR.

The solution is to rely on the field ContactCount, which is accurate as the correct information are packed at the begining of the frame. Unfortunately, CountactCount is most of the time at the end of the report. The solution is to pick it when we have the whole report in raw_event.

HID: multitouch: Add support for button type usage According to [1], Windows Precision Touchpad devices must supply a button type usage in the device capabilities feature report. A value of 0 indicates that the device contains a depressible button (i.e. it's a click-pad) whereas a value of 1 indicates a non-depressible button. Add support for this usage and set INPUT_PROP_BUTTONPAD on the touchpad input device whenever a depressible button is present.

HID: multitouch: remove registered devices with default behavior The default multitouch protocol class in use since the kernel v3.9 is working quite well. Since its inclusion, the only devices we had to tweak were those who really need quirks (GeneralTouch, FocalTech and Wistron, the 3 of them are Win 7 certified ones). The flow of new unhandled devices has stopped, which is great and I think it's time to reduce the list of registered device. This commit removes only the registration in the kernel of devices that use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I checked all the recordings I have, and the produced input device and events are the same before and after applying the patch. This gives two benefits: - remove a bunch of lines of codes - prevent bad handling of existing registered devices which are using a different protocol while using the same VID/PID (I got the case of a Quanta 3008 recently). I also removed the associated classes (MT_CLS*). I kept their #define in case people use the new_id sysfs node with a non standard class (their should be really few people now, but we never now). This is why there are /* reserved .... */. Last, I add a comment on top of mt_devices[] definition to remember people (and myself) not to include devices for the beauty of it. To people still trying to add devices with the default class: """ Guys, try out your device under a kernel greater or equal to v3.9. If it works, you are all set. Adding your VID/PID to the kernel only brings us overload and you won't get anything from it _because_ even a backport of this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or even 3.8.

The switch between the two is controlled by a physical switch, and the firmware sends the events on the right interface (mouse, keyboard or multitouch). This patch enables the multitouch interface of this device to work. We need to manually set the device as a trackpad (we cannot infer it from the reports descriptors as the device works under Windows, a system that does not allow multitouch touchpad). We also need to set the hid feature MAX CONTACT NUMBER to 2 or the device stops sending events once it has been pressed by two touches.

HID: multitouch: support Perixx PERIPAD 701 Perixx Peripad 701 is an hybrid device which presents a touchpad and a keyboard on the same surface. The switch between the two is controlled by a physical switch, and the firmware sends the events on the right interface (mouse, keyboard or multitouch). This patch enables the multitouch interface of this device to work. We need to manually set the device as a trackpad (we cannot infer it from the reports descriptors as the device works under Windows, a system that does not allow multitouch touchpad). We also need to set the hid feature MAX CONTACT NUMBER to 2 or the device stops sending events once it has been pressed by two touches.

Given that we did not checked if one was previously assigned, we were dealing with the ignored featured and we should never have been able to switch this panel into the multitouch mode. However, the firmware presents an other bugs which allowed 6d4f5440 to counteract the faulty report descriptor. When we request the values of the feature 5, the firmware answers "03 03 00". The fields are correct but the report id is wrong. Before 6d4f5440, we retrieved all the features and injected them in the system. So when we called report 5, we injected in the system the report 3 with the values "03 00". Setting the second input mode to 03 in this report changed it to "03 03" and the touchpad switched to the mt mode. We could have set anything in the second field because the actual value (the first 03 in this report) was given by the query of report ID 5. To sum up: 2 bugs in the firmware were hiding that we were accessing the wrong feature.

HID: multitouch: add control of the feature "Maximum Contact Number" Some devices, like Perixx Peripad 701 do not work if the feature "Maximum Contact Number" is not set to the right value. This patch allows hid-multitouch to control this feature. If the programmer fills the field maxcontacts in the mt_class, then the driver will set the feature to this value. It is safe for current drivers as the feature is read/write in the HID norm and all devices should implement the norm.

HID: multitouch: get maxcontacts also from logical_max value Win8 devices are required to present the feature "Maximum Contact Number". Fortunately all win7 devices I've seen presents this feature. If the current value is 0, then, the driver can get the actual supported contact count by refering to the logical_max. This win8 specification ensures that logical_max may not be above 250. This also allows us to detect when devices like irtouch or stantum reports an obviously wrong value of 255.

HID: multitouch: add support for Nexio 42" panel This device is the worst device I saw. It keeps TipSwitch and InRange at 1 for fingers that are not touching the panel. The solution is to rely on the field ContactCount, which is accurate as the correct information are packed at the begining of the frame. Unfortunately, CountactCount is most of the time at the end of the report. The solution is to pick it when we have the whole report in raw_event.

HID: multitouch: add support for Nexio 42" panel This device is the worst device I saw. It keeps TipSwitch and InRange at 1 for fingers that are not touching the panel. The solution is to rely on the field ContactCount, which is accurate as the correct information are packed at the begining of the frame.

Revert "HID: multitouch: decide if hid-multitouch needs to handle mt devices" This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch needs to handle mt devices"). The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

HID: multitouch: add handling for pen in dual-sensors device Dual sensors devices reports pen and touch on two different reports. Using the quirk HID_QUIRK_MULTI_INPUT allows us to create a new input device to forward pen events. The quirk HID_QUIRK_NO_EMPTY_INPUT avoids the creation of input devices for the not used mouse emulation present on Win7 certified devices. Since hid-multitouch sets the quirk HID_QUIRK_NO_INPUT_SYNC, we need to manually send SYN events for pen report too.

HID: do not init input reports for Win 8 multitouch devices Some multitouch screens do not like to be polled for input reports. However, the Win8 spec says that all touches should be sent during each report, making the initialization of reports unnecessary. The Win7 spec is less precise, so do not use this for those devices. Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to introduce a quirk for each problematic device. This quirk makes the driver behave the same way the Win 8 does. It actually retrieves the features, but not the inputs.

HID: multitouch: add control of the feature "Maximum Contact Number" Some devices, like Perixx Peripad 701 do not work if the feature "Maximum Contact Number" is not set to the right value. This patch allows hid-multitouch to control this feature. If the programmer fills the field maxcontacts in the mt_class, then the driver will set the feature to this value. It is safe for current drivers as the feature is read/write in the HID norm and all devices should implement the norm.

HID: multitouch: prevent memleak with the allocated name mt_free_input_name() was never called during .remove(): hid_hw_stop() removes the hid_input items in hdev->inputs, and so the list is therefore empty after the call. In the end, we never free the special names that has been allocated during .probe(). Restore the original name before freeing it to avoid acessing already freed pointer.

HID: multitouch: remove registered devices with default behavior The default multitouch protocol class in use since the kernel v3.9 is working quite well. Since its inclusion, the only devices we had to tweak were those who really need quirks (GeneralTouch, FocalTech and Wistron, the 3 of them are Win 7 certified ones). The flow of new unhandled devices has stopped, which is great and I think it's time to reduce the list of registered device. This commit removes only the registration in the kernel of devices that use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I checked all the recordings I have, and the produced input device and events are the same before and after applying the patch. This gives two benefits: - remove a bunch of lines of codes - prevent bad handling of existing registered devices which are using a different protocol while using the same VID/PID (I got the case of a Quanta 3008 recently). I also removed the associated classes (MT_CLS*). I kept their #define in case people use the new_id sysfs node with a non standard class (their should be really few people now, but we never now). This is why there are /* reserved .... */. Last, I add a comment on top of mt_devices[] definition to remember people (and myself) not to include devices for the beauty of it. To people still trying to add devices with the default class: """ Guys, try out your device under a kernel greater or equal to v3.9. If it works, you are all set. Adding your VID/PID to the kernel only brings us overload and you won't get anything from it _because_ even a backport of this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or even 3.8. So if it works, it works. If it does not work, then yes, submit a patch or call for help. In any cases, if you want me to do regression tests, I'd be happy to get some traces of your device. But I won't patch the kernel if it works. """ Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

HID: hid-multitouch: Only match MT interfaces All known hid-multitouch devices currently match any device group. However, some devices present interfaces belonging to different groups, resulting in a race between the hid-generic and hid-multitouch modules. This patch narrows the MT device list to match only HID_GROUP_MULTITOUCH, which solves the problem. As an exception, the USB_DEVICE_ID_CYPRESS_TRUETOUCH panel is not modified, in order to suppress the unwanted extra interfaces of the device.

The switch between the two is controlled by a physical switch, and the firmware sends the events on the right interface (mouse, keyboard or multitouch). This patch enables the multitouch interface of this device to work. We need to manually set the device as a trackpad (we cannot infer it from the reports descriptors as the device works under Windows, a system that does not allow multitouch touchpad).

HID: multitouch: make MT_CLS_ALWAYS_TRUE the new default class By running a test on all the traces of the devices I have, I noticed that the class MT_CLS_ALWAYS_TRUE could handle all the devices I've seen so far without any other quirks. I guess this is the behavior Win 7 requires in its driver. We can change the default class then and keep the existing classes for backward compatibility and performances for some of them.

HID: hid-multitouch: Switch to device groups Switch the driver over to device group handling. By adding the HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer match multitouch devices. By adding the HID_GROUP_MULTITOUCH entry to the device list, hid-multitouch will match all unknown multitouch devices, and udev will automatically load the module. Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling can be removed. Since all HID MT devices have HID_DG_CONTACTID, they can be removed from the hid_have_special_driver list. With this patch, the unknown device ids are no longer NULL, so the code is modified to check for the generic entry instead.

HID: detect Win 8 multitouch devices in core Detecting Win 8 multitouch devices in core allows us to set quirks before the device is parsed through hid_hw_start(). It also simplifies the detection of those devices in hid-multitouch and makes the handling of those devices cleaner. As Win 8 multitouch panels are in the group multitouch and rely on a special feature to be detected, this patch adds a bitfield in the parser.
