2010-05-25HID: roccat: propagate special events of roccat hardware to userspaceStefan Achatz6-0/+526
Module roccat is a char device used to report special events of roccat hardware to userland. These events include requests for on-screen-display of profile or dpi settings or requests for execution of macro sequences that are not stored in device. The information in these events depends on hid device implementation and contains data that is not available in a single hid event or else hidraw could have been used. It is inspired by hidraw, but uses only one circular buffer for all readers. The device is as generic as possible so that the functionality is usable by all (kone and upcomming) roccat device drivers.

2010-05-21HID: fix up 'EMBEDDED' mess in KconfigJiri Kosina1-31/+16
The whole point of making some of the drivers automatically selected unless 'EMBEDDED' was to handle quirks transparently after their separation from the generic core. Over time, some of the later-added quirks grew into more standalone drivers, implementing non-trivial features a being larger than a few bytes of code. In addition to that, some of the standalone drivers don't make sense for 99.9% of the users, as they are very specific to rare devices. Therefore build by default in only those drivers which - we historically used to support even before quirk separation from the core code - are isolated enough and likely to hit quite large portion of the users anyway (Microsoft, Logitech) Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-05-20USB: remove uses of URB_NO_SETUP_DMA_MAPAlan Stern3-11/+6
This patch (as1350) removes all usages of coherent buffers for USB control-request setup-packet buffers. There's no good reason to reserve coherent memory for these things; control requests are hardly ever used in large quantity (the major exception is firmware transfers, and they aren't time-critical). Furthermore, only seven drivers used it. We might as well always use streaming DMA mappings for setup-packet buffers, and remove some extra complexity from usbcore. The DMA-mapping portion of hcd.c is currently in flux. A separate patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP after everything else settles down. The removal should go smoothly, as by then nobody will be using it. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-05-18HID: hidraw: Use Interrupt Endpoint for OUT Transfers if AvailableAlan Ott1-10/+30
This patch makes the hidraw driver use the first Interrupt OUT endpoint for HID transfers to the device if such an endpoint exists. This is consistent with the behavior of the hiddev driver, and the logic is similar. From the USB HID specification: The Interrupt Out pipe is optional. If a device declares an Interrupt Out endpoint then Output reports are transmitted by the host to the device through the Interrupt Out endpoint. If no Interrupt Out endpoint is declared then Output reports are transmitted to a device through the Control endpoint, using Set_Report(Output) requests.

2010-05-12HID: magicmouse: fix input registrationJiri Kosina1-1/+4
When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has claimed the magicmouse device, and probe routine bails out. Which is not what we want. This happens because magicmouse driver is instantiating the connection to Input subsystem itself, and since commit 28918c211d86b ("HID: magicmouse: fix oops after device removal") the HID core is not registering input device itself. Fix this by letting HID core register the input device (so that hid_hw_start() succeeds, as the device is claimed by at least one subsystem) and de-register it again later before proceeding with proper input setup.

2010-05-11HID: ntrig: add sensitivity and responsiveness supportRafi Rubin1-9/+211
The old rejection size thresholds were too high for the 12" devices. Larger surfaces like the Dell Studio17 exacerbated the problem since contact size is reported on the same logical scale, making a contact look smaller to the larger screen. Since we have observed erroneous ghost events from these devices we still need to filter the incoming stream. The prior size threshold filter is still in place, though with defaults set to leave it off. This patch adds the two new classes of filters, those that reject live frames before activation, and those that reject empty frames until deactivation. These filters are expressed in terms of a simple state machine for clarity (I hope). The activation filter has two components, slack and size, events are discarded until either is satisfied. Slack is defined as the number of seemingly good contacts to read before accepting the stream as valid (if the threshold is reached in the middle of a frame the remainder of that frame is still discarded). The deactivation filter discards empty frames until hitting a deactivate slack. This time measured in frames. N-Trig devices emit 5-8 (observed so far) empty frames at the end of multitouch activity. Ignoring the first few enables us to safely and gracefully handle erroneous empty frames, thus preventing a change in the tool state which would otherwise result in things like broken lines or dragged objects being dropped in bad places. Also, now that devices with different logical densities have been observed, the aforementioned sizes are scaled from physical to logical scales once those scales are identified. Hopefully this should mean that a given threshold value means the same thing across differing devices. Signed-off-by: Rafi Rubin <rafi@seas.upenn.edu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-05-07HID: fix suspend crash by moving initializations earlierAlan Stern1-7/+6
Although the usbhid driver allocates its usbhid structure in the probe routine, several critical fields in that structure don't get initialized until usbhid_start(). However if report descriptor parsing fails then usbhid_start() is never called. This leads to problems during system suspend -- the system will freeze.
