2012-10-08Input: extend the number of event (and other) devicesDmitry Torokhov4-253/+180
Extend the amount of character devices, such as eventX, mouseX and jsX, from a hard limit of 32 per input handler to about 1024 shared across all handlers. To be compatible with legacy installations input handlers will start creating char devices with minors in their legacy range, however once legacy range is exhausted they will start allocating minors from the dynamic range 256-1024.

2012-10-05Input: wacom - introduce wacom_fix_phy_from_hidJason Gerecke1-0/+71
The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine the physical size of the touch sensor since the pen and touch are on separate USB devices. The physical size is, however, provided in the HID descriptor, just scaled to a unit we don't use. This patch introduces the function wacom_fix_phy_from_hid to let us make use of the unit and exponent data provided by HID to set the [xy]_phy variables to an appropriate value. This function relies on a trimmed-down version of hidinput_calc_abs_res from the hid-input.c.

This changes how the touch packets for Intuos5 and 3rd-gen Bamboo are interpreted, so that proper values for the MAJOR and MINOR axes are reported. Instead of using the amplitude field (data[6]), we use the size field (data[5]) and do some calculation to transform it from a scaled-down area into axis lengths. Note that even though we assume a circular contact, both MAJOR and MINOR are reported since the resolution of the X and Y axes differ.

2012-09-19Input: bcm5974 - Convert to MT-BHenrik Rydberg1-45/+28
Use of the in-kernel tracking code to convert the driver to MT-B. With ten fingers on the pad, the in-kernel tracking adds approximately 25 us to the maximum irqsoff latency. Under normal workloads, however, the tracking has no measurable effect.

2012-09-19Input: bcm5974 - Drop the logical dimensionsHenrik Rydberg1-144/+111
The logical scale is used to produce special finger width values to userspace, but has become an unnecessary restriction for everything else. Also, the bcm5974 trackpads are very accurate and work well without hysteresis. This patch simplifies the driver and device data by removing the logical scale, and by moving the special synaptics code out of the main path. Also add the orientation range, needed in a subsequent patch, to the device configuration.

2012-09-19Input: bcm5974 - only setup button urb for TYPE1 devicesHenrik Rydberg1-17/+26
The early generations with this trackpad used the separate mouse interface to produce button events. With the introduction of the button pads, this information was moved to the trackpad interface, leaving the mouse interface unused. The driver is still setting up both interfaces, which has not caused any problems - until now. It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the driver may return an ENOSPC upon bt_urb submission, resulting in a failure to open the device. This happens everytime on the MacBookPro Retina (and likely on other mid-2012 models), but earlier MacBook models seem to work fine. This patch skips the bt_urb setup for TYPE2 devices, which arguably should have been done in the first place.

Most MT drivers perform the same actions on frame synchronization. Some actions, like dropping unseen contacts, are also unnecessarily complex. Collect common frame synchronization tasks in a new function, input_mt_sync_frame(). Depending on the flags set, it drops unseen contacts and performs pointer emulation.

2012-09-19Input: Send events one packet at a timeHenrik Rydberg1-53/+123
On heavy event loads, such as a multitouch driver, the irqsoff latency can be as high as 250 us. By accumulating a frame worth of data before passing it on, the latency can be dramatically reduced. As a side effect, the special EV_SYN handling can be removed, since the frame is now atomic. This patch adds the events() handler callback and uses it if it exists. The latency is improved by 50 us even without the callback.

The events-per-packet estimate has so far been used by MT devices only. This patch adjusts the packet buffer size to also accomodate the KEY and MSC events. Keyboards normally send one or two keys at a time. MT devices normally send a number of button keys along with the MT information. The buffer size chosen here covers those cases, and matches the default buffer size in evdev. Since the input estimate is now preferred, remove the special input-mt estimate.
