2011-07-27[media] rc-core support for Microsoft IR keyboard/mouseJarod Wilson
This is a custom IR protocol decoder, for the RC-6-ish protocol used by the Microsoft Remote Keyboard, apparently developed internally at Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and transceiver requirements and specifications document, which also touches on this IR keyboard/mouse device. Its a standard keyboard with embedded thumb stick mouse pointer and mouse buttons, along with a number of media keys. The media keys are standard RC-6, identical to the signals from the stock MCE remotes, and will be handled as such. The keyboard and mouse signals will be decoded and delivered to the system by an input device registered specifically by this driver. Successfully tested with multiple mceusb-driven transceivers, as well as with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware with enough sampling resolution should be able to use this decoder, nothing about it is at all receiver-hardware-specific. This work is inspired by lirc_mod_mce: The documentation there and code aided in understanding and decoding the protocol, but the bulk of the code is actually borrowed more from the existing in-kernel decoders than anything. I did recycle the keyboard keycode table, a few defines, and some of the keyboard and mouse data parsing bits from lirc_mod_mce though. Special thanks to James Meyer for providing the hardware, and being patient with me as I took forever to get around to writing this. callback routine to ensure we don't get any stuck keys, and used symbolic names for the keytable. Also cc'ing Florian this time, who I believe is the original mod-mce author...

2011-07-27[media] v4l2-ctrls: improve discovery of controls of the same clusterHans Verkuil
The implementation of VIDIOC_G/S/TRY_EXT_CTRLS in the control framework has to figure out which controls in the control list belong to the same cluster. Since controls belonging to the same cluster need to be handled as a unit, this is important information. It did that by going over the controls in the list and for each control that belonged to a multi-control cluster it would walk the remainder of the list to try and find controls that belong to that same cluster. This approach has two disadvantages: 1) it was a potentially quadratic algorithm (although highly unlikely that it would ever be that bad in practice). 2) it took place with the control handler's lock held. Since we want to make it possible in the future to change control values from interrupt context, doing a lot of work while holding a lock is not a good idea. In the new code the algorithm is no longer quadratic but linear in the number of controls in the list. Also, it now can be done beforehand. Another change that was made was to so the try and set at the same time. Before when S_TRY_EXT_CTRLS was called it would 'try' the controls first, and then it would 'set' them. The idea was that any 'try' errors would prevent the 'set' from happening, thus avoiding having partially set control lists. However, this caused more problems than it solved because between the 'try' and the 'set' changes might have happened, so it had to try a second time, and since actual controls with a try_ctrl op are very rare (and those that we have just adjust values and do not return an error), I've decided to drop that two-stage approach and just combine try and set.

2011-07-27[media] v4l2-event: add optional merge and replace callbacksHans Verkuil
When the event queue for a subscribed event is full, then the oldest event is dropped. It would be nice if the contents of that oldest event could be merged with the next-oldest. That way no information is lost, only intermediate steps are lost. This patch adds optional replace() (called when only one kevent was allocated) and merge() (called when more than one kevent was allocated) callbacks that will be called to do this job. These two callbacks are implemented for the V4L2_EVENT_CTRL event. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of ↵Hans Verkuil
just per-fh The driver had to decide how many events to allocate when the v4l2_fh struct was created. It was possible to add more events afterwards, but there was no way to ensure that you wouldn't miss important events if the event queue would fill up for that filehandle. In addition, once there were no more free events, any new events were simply dropped on the floor. For the control event in particular this made life very difficult since control status/value changes could just be missed if the number of allocated events and the speed at which the application read events was too low to keep up with the number of generated events. The application would have no idea what the latest state was for a control since it could have missed the latest control change. So this patch makes some major changes in how events are allocated. Instead of allocating events per-filehandle they are now allocated when subscribing an event. So for that particular event type N events (determined by the driver) are allocated. Those events are reserved for that particular event type. This ensures that you will not miss events for a particular type altogether. In addition, if there are N events in use and a new event is raised, then the oldest event is dropped and the new one is added. So the latest event is always available. This can be further improved by adding the ability to merge the state of two events together, ensuring that no data is lost at all. This will be added in the next patch. This also makes it possible to allow the user to determine the number of events that will be allocated. This is not implemented at the moment, but would be trivial.

2011-07-27[media] v4l2-ctrls/event: remove struct v4l2_ctrl_fh, instead use ↵Hans Verkuil
v4l2_subscribed_event The v4l2_ctrl_fh struct connected v4l2_ctrl with v4l2_fh so the control would know which filehandles subscribed to it. However, it is much easier to use struct v4l2_subscribed_event directly for that and get rid of that intermediate struct.

2011-07-27[media] v4l2-events/fh: merge v4l2_events into v4l2_fhHans Verkuil
Drivers that supported events used to be rare, but now that controls can also raise events this will become much more common since almost all drivers have controls. This means that keeping struct v4l2_events as a separate struct make no more sense. Merging it into struct v4l2_fh simplifies things substantially as it is now an integral part of the filehandle struct.
