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. Signed-off-by:

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. Signed-off-by:

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. Tested-by:

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. Tested-by:

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. Tested-by:

With the INPUT_MT_TRACK flag set, the function input_mt_assign_slots() can be used to match a new set of contacts against the currently used slots. The algorithm used is based on Lagrange relaxation, and performs very well in practice; slower than mtdev for a few corner cases, but faster in most commonly occuring cases. Tested-by:

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. With init flags and frame synchronization in place, most MT drivers can be simplified. First out are the bcm5974 and hid-multitouch drivers, following this patch. Reviewed-and-tested-by:

By sending a full frame of events at the same time, the irqsoff latency at heavy load is brought down from 200 us to 100 us. Cc: Daniel Kurtz <djkurtz@chromium.org> Tested-by:

Henrik Rydberg authored
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. Cc: Daniel Kurtz <djkurtz@chromium.org> Tested-by:

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. Reviewed-and-tested-by:

A formal check of the two affected ioctls in drivers/char/vt_ioctl.c (introduced in 04c71976 ) and a test using x86 kbd 1.15.1 on a so patched x86_64 kernel both confirm that KD[GS]KBDIACRUC are ioctl32() compatible.

Andreas Bombe reported that the added ktime_t overflow checking added to timespec_valid in commit 4e8b1452 ("time: Improve sanity checking of timekeeping inputs") was causing problems with X.org because it caused timeouts larger then KTIME_T to be invalid. Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid. This patch splits the ktime_t overflow checking into a new timespec_valid_strict function, and converts the timekeeping codes internal checking to use this more strict function.
