| | | | | | | | | | | | | | | | | Guitar-Hero comes with a drums extension. Use the newly introduced input drums-bits to report this back to user-space. This is a usual extension like any other device. Nothing special to take care of. We report this to user-space as "Nintendo Wii Remote Drums". There are other drums (like "RockBand" drums) which we currently do not support and maybe will at some point. However, it is quite likely that we can report these via the same interface. This allows user-space to work with them without knowing the exact branding. I couldn't find anyone who owns a "RockBand" device, though.

* HID: wiimote: work around broken DRM_KAI on GEN10David Herrmann2013-08-051-4/+6
| | | | | | | | | | | | | | | | | | | | | GEN10 and earlier devices seem to not support DRM_KAI if we run in basic IR mode. Use DRM_KAIE instead. This might increases overhead slightly as the extension port is read and streamed but we stream accelerometer data constantly, too, so this is negligible. Note that our parsers are hardcoded on IR-formats, so we cannot actually use 96-bit IR DRMs for basic IR data. We would have to adjust the parsers. But as only GEN20 and newer support this, we simply avoid mixed DRMs. This fixes a bug where GEN10 devices didn't provide IR data if accelerometer and IR are enabled simultaneously. As a workaround, you can enable DRM_KAIE without this patch via (disables device power-management): echo "37" >/sys/kernel/debug/hid/<dev>/drm Cc: stable@vger.kernel.org Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reported-by: Nicolas Adenis-Lamarre <nicolas.adenis.lamarre@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: support Nintendo Wii U Pro ControllerDavid Herrmann2013-06-271-0/+23
| | | | | | | | | | | | | | | | | | | | | | The Wii U Pro Controller is a new Nintendo remote device that looks very similar to the XBox controller. It has nearly the same features and uses the same protocol as the Wii Remote. We add a new wiimote extension device so the Pro Controller is properly detected and supported. The device reports MP support, which is odd and I couldn't get it working, yet. Hence, we disable MP registers for now. Further investigation is needed to see what extra capabilities are provided. There are some other unknown bits in the extension reports that I couldn't figure out what they do. You can use hidraw to access these if you're interested. We might want to hook up the "charging" and "USB" bits to the battery device so user-space can query whether it is currently charged via USB. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: discard invalid EXT data reportsDavid Herrmann2013-06-031-1/+9
| | | | | | | | | | | If an extension device isn't initialized properly, or during hardware initialization, a device might send extension data which is all 0xff. This is ambigious because this is also a valid normal data report. But it is impossible, under normal conditions, to trigger valid reports with all 0xff. Hence, we can safely ignore them.

* HID: wiimote: init EXT/MP during device detectionDavid Herrmann2013-06-031-1/+1
| | | | | | | | | | | | | | | | We normally get EXT hotplug events or poll for MP hotplugging so we don't need to force extension port initialization during device setup. But for gen20 devices, we disable MP polling because MP is always present. However, this prevents MP initialization during device setup and users need to plug another extension to trigger EXT/MP detection. Therefore, we now trigger EXT/MP detection during device setup automatically. This also avoids slightly delayed extension detection and provides sysfs child-devices prior to the "changed"-uevent during device setup.

* HID: wiimote: add MP quirksDavid Herrmann2013-06-031-5/+20
| | | | | | | | | | | | | | Devices which have built-in motion plus ports don't need MP detection logic. The new WIIMOD_BUILTIN_MP modules sets the WIIPROTO_FLAG_BUILTIN_MP flag which disables polling for MP. Some other devices erroneously report that they support motion-plus. For these devices and all devices without extension ports, we load WIIMOD_NO_MP which sets WIIPROTO_FLAG_NO_MP. This effectively disables all MP detection logic.

* HID: wiimote: add sysfs extension/device-type attrsDavid Herrmann2013-06-031-1/+105
| | | | | | | | | | | | | Two new attributes, "extension" and "devtype" now allow user-space to read the extension type and device type. As device detection is asynchronous, we send a CHANGED event after it is done. This also allows user-space to wait for a device to settle before opening its input event devices. The "extension" device is compatible with the old "extension" sysfs field (which was registered by the static extension support code).

* HID: wiimote: add extension hotplug supportDavid Herrmann2013-06-031-25/+644
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Wii Remote has several extension ports. The first port (EXT) provides hotplug events whenever an extension is plugged. The second port (MP) does not provide hotplug events by default. Instead, we have to map MP into EXT to get events for it. This patch introduces hotplug support for extensions. It is fairly complicated to get this right because the Wii Remote sends a lot of noise-hotplug events while activating extension ports. We need to filter the events and only handle the events that are real hotplug events. Mapping MP into EXT is easy. But if we want both, MP _and_ EXT at the same time, we need to map MP into EXT and enable a passthrough-mode. This will then send real EXT events through the mapped MP interleaved with real MP events. But once MP is mapped, we no longer have access to the real EXT registers so we need to perform setup _before_ mapping MP. Furthermore, we no longer can read EXT IDs so we cannot verify if EXT is still the same extension that we expect it to be. We deal with this by unmapping MP whenever we got into a situation where EXT might have changed. We then re-read EXT and MP and remap everything. The real Wii Console takes a fairly easy approach: It simply reconnects to the device on hotplug events that it didn't expect. So if a program wants MP events, but MP is disconnected, it fails and reconnects so it can wait for MP hotplug events again. This simplifies hotplugging a lot because we just react on PLUG events and ignore UNPLUG events. The more sophisticated Wii applications avoid reconnection (well, they still reconnect during many weird events, but at least not during UNPLUG) but they start polling the device. This allows them to disable the device, poll for the extension ports to settle and then initialize them again. Unfortunately, this approach fails whenever an extension is replugged while it is initialized. We would loose UNPLUG events and polling the device later will give unreliable results because the extension port might be in some weird state, even though it's actually unplugged. Our approach is a real HOTPLUG approch. We keep track of the EXT and mapped MP hotplug events whenever they occur. We then re-evaluate the device state and initialize any possible new extension or deinitialize any gone extension. Only during initialization, we set an extension port ACTIVE. However, during an unplug event we mark them as INACTIVE. This guarantess that a fast UNPLUG -> PLUG event sequence doesn't keep them marked as PLUGGED+ACTIVE but only PLUGGED. To deal with annoying noise-hotplug events during extension mapping, we simply rescan the device before performing any mapping. This allows us to ignore all the noise events as long as the device is in the correct state. Long story short: EXT and MP registers are sparsely known and we need to jump through hoops to get reliable HOTPLUG working. But while Nintendo needs *FOUR* Bluetooth reconnections for the shortest imaginable boot->menu->game->menu->shutdown sequence, we now need *ZERO*. As always, 3rd party devices tend to break whenever we behave differently than the original Wii. So there are also devices which _expect_ a disconnect after UNPLUG. Obviously, these devices won't benefit from this patch. But all official devices were tested extensively and work great during any hotplug sequence. Yay!

| | | | | | | | | | | | | | | | | | | To avoid loading all sub-device drivers for every Wii Remote, even though the required hardware might not be available, we introduce a module layer. The module layer specifies which sub-devices are available on each device-type. After device detection, we only load the modules for the detected device. If module loading fails, we unload everything and mark the device as WIIMOTE_DEV_UNKNOWN. As long as a device is marked as "unknown", no sub-devices will be used and the device is considered unsupported. All the different sub-devices, including KEYS, RUMBLE, BATTERY, LEDS, ACCELEROMETER, IR and more will be ported in follow-up patches to the new module layer.

| | | | | | | | | | | | | | | Our output queue is asynchronous but synchronous reports may wait for a response to their request. Therefore, wake them up unconditionally if an output report couldn't be sent. But keep the report ID intact so we don't incorrectly assume our request succeeded. Note that the underlying connection is required to be reliable and does retransmission itself. So it is safe to assume that if the transmission fails, the device is in inconsistent state. Hence, we abort every request if any output report fails. No need to verify which report failed. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: use cached battery values on I/O failureDavid Herrmann2013-06-031-7/+7
| | | | | | | | | | | | | | | | Battery reports are sent along every status report of the Wii Remote. So chances are pretty high that we have an up-to-date battery cache at any time. Therefore, initialize the battery-cache to 100% and then return battery values from the cache if the query fails. This works around a power_supply limitation in that it requires us to be able to query the device during power_supply registration and removal. Otherwise, "add" or "remove" udev events are not sent. If we answer these requests from our cache instead, we avoid dropping these events and no longer cause warnings printed.

* HID: wiimote: add device detectionDavid Herrmann2013-06-031-1/+152
| | | | | | | | | | | | | | | | | | | | | | | | | Nintendo produced many different devices that are internally based on the Wii Remote protocol but provide different peripherals. To support these devices, we need to schedule a device detection during initialization. Device detection includes requesting a status report, reading extension information and then evaluating which device we may be dealing with. We currently detect gen1 and gen2 Wii Remote devices. All other devices are marked as generic devices. More detections will be added later. In followup patches we will be using these device IDs to control which peripherals to initialize. For instance if a device is known to have no IR camera, there is no need to provide the IR input device nor trying to access IR registers. In fact, there are 3rd party devices that break if we try things like this (hurray!). The init_worker will be scheduled whenever we get hotplug events. This isn't implemented, yet and will be added later. However, we need to make sure that this worker can be called multiple times.

| | | | | | | | Keep track of current drm and add new debugfs file which reads or writes the current DRM. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Allow direct eeprom accessDavid Herrmann2011-11-221-8/+2
| | | | | | | | | | | | | The wiimote provides direct access to parts of its eeprom. This implements read support for small chunks of the eeprom. This isn't very fast but prevents the reader from blocking the wiimote stream for too long. Write support is not yet supported as the wiimote breaks if we overwrite its memory. Use hidraw to reverse-engineer the eeprom before implementing write support here. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Add debugfs support stubsDavid Herrmann2011-11-221-0/+5
| | | | | | | | | Add initializer and deinitializer for debugfs support. This will later allow raw eeprom access and direct DRM modifications to debug wiimote behaviour and further protocol reverse-engineerings.

* HID: wiimote: Add extension handler stubsDavid Herrmann2011-11-221-0/+6
| | | | | | | | | | | | | All supported extensions report data as 6 byte block. All DRMs with extension data provide at least 6 extension bytes. Hence a generic handler for all extension bytes is sufficient and can be called on all DRMs. The handler distinguishes the input and passes it to the right handler. Motion+ passes data interleaved so we can have Motion+ and a regular extension enabled simultaneously.

* HID: wiimote: Add extension support stubDavid Herrmann2011-11-221-4/+19
| | | | | | | | | | | | | | | | | | | | | The wiimote supports several extensions. This adds a separate source file which handles all extensions and can be disabled at compile-time. The driver reacts on "plug"-events on the extension port and starts a worker which initializes or deinitializes the extensions. Currently, the initialization logic is not fully understood and we can only detect and enable all extensions when all extensions are deactivated. Therefore, we need to disable all extensions, then detect and activate them again to react on "plug"-events. However, deactivating extensions will generate a new "plug"-event and we will never leave that loop. Hence, we only support extensions if they are plugged before the wiimote is connected (or before the ext-input device is opened). In the future we may support full extension hotplug support, but reverse-engineering this may take a while.

* HID: wiimote: Move common symbols into headerDavid Herrmann2011-11-221-131/+3
| | | | | | | | Wiimote extension and sound support need access to several symbols so move them into a new header. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Rename driver to allow multiple source filesDavid Herrmann2011-11-221-0/+1346
Extension and sound support for the wiimote are quite complex and will be implemented in separate source files. Hence rename the current driver to "-core" suffix so multiple files can be linked into this module.
