2013-10-07HID: wiimote: fix FF deadlockDavid Herrmann
The input core has an internal spinlock that is acquired during event injection via input_event() and friends but also held during FF callbacks. That means, there is no way to share a lock between event-injection and FF handling. Unfortunately, this is what is required for wiimote state tracking and what we do with state.lock and input->lock. This deadlock can be triggered when using continuous data reporting and FF on a wiimote device at the same time. I takes me at least 30m of stress-testing to trigger it but users reported considerably shorter times (http://bpaste.net/show/132504/) when using some gaming-console emulators. The real problem is that we have two copies of internal state, one in the wiimote objects and the other in the input device. As the input-lock is not supposed to be accessed from outside of input-core, we have no other chance than offloading FF handling into a worker. This actually works pretty nice and also allows to implictly merge fast rumble changes into a single request. Due to the 3-layered workers (rumble+queue+l2cap) this might reduce FF responsiveness. Initial tests were fine so lets fix the race first and if it turns out to be too slow we can always handle FF out-of-band and skip the queue-worker.

2013-09-26HID: uhid: allocate static minorDavid Herrmann
udev has this nice feature of creating "dead" /dev/<node> device-nodes if it finds a devnode:<node> modalias. Once the node is accessed, the kernel automatically loads the module that provides the node. However, this requires udev to know the major:minor code to use for the node. This feature was introduced by: commit 578454ff7eab61d13a26b568f99a89a2c9edc881 Author: Kay Sievers <kay.sievers@vrfy.org> Date: Thu May 20 18:07:20 2010 +0200 driver core: add devname module aliases to allow module on-demand auto-loading However, uhid uses dynamic minor numbers so this doesn't actually work. We need to load uhid to know which minor it's going to use. Hence, allocate a static minor (just like uinput does) and we're good to go.

2013-09-04HID: wiimote: add support for Guitar-Hero guitarsNicolas Adenis-Lamarre
Apart from drums, Guitar-Hero also ships with guitars. Use the recently introduced input ABS/BTN-bits to report this to user-space. Devices are reported as "Nintendo Wii Remote Guitar". If I ever get my hands on "RockBand" guitars, I will try to report them via the same interface so user-space does not have to bother which device it deals with.

2013-09-04HID: wiimote: add support for Guitar-Hero drumsDavid Herrmann
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.
