touchpad: always call into the the tap state machine

the tap state machine, leaving it in its current state. The touch generating
that event however may have triggered state changes.

For some tap/click combinations this gives us either double press/release
events or an inconsistent order of events. Those issues include:
* a really short physical click causes a click + tap-click
* a really short physical click on the right software button causes a right
  click + left tap-click
* tap + click causes double button left press events

To avoid these, notify the tap code that a button event has occured and
process that accordingly. Depending on the state this may either continue to
the DEAD state or release the current tap button and then go to the DEAD

actually perform a slight curve, not a straight line.

Hence - drop the direction lock, but increase the threshold a little. It

Add support for the top softbutton area found on some laptops.

For details of how this works, see the updated
doc/touchpad-softbutton-state-machine.svg diagram.

Basically this mirrors the state-machine for the bottom softbutton area, with
one exception, if a finger stays at least inner timeout milliseconds in the
top button area and then moves out of it, it will be ignored rather then
become the pointer. This is done so that people using the top buttons together
with a trackstick and accidentally move their finger out of the upper area
don't get spurious pointer movements from the finger on the trackpad.

This behavior is indentical to xf86-input-synaptics, which also ignores
movements from touches which start in the top button area.

Change internal timestamps to uint64_t to properly deal with wrapping

We store timestamps in ms since system boot (CLOCK_MONOTONIC). This will wrap

I've considered making our code wrapping safe, but that won't work. We also
use our internal timestamps to program timer-fds for timeouts. And we store
ms in a single integer but the kernel uses 2 integers, one for seconds and
one for usec/nanosec. So at 32 bits our ms containing integer will wrap
in 50 days, while the kernels seconds storing integer lasts a lot longer.
So when we wrap our ms timestamps, we will be programming the timer-fds
with a seconds value in the past.

So change all our internal timestamps to uint64_t to avoid the wrapping
when programming the timer-fds. Note that we move from 64-bit timestamps to
32-bit timestamps when calling the foo_notify_bar functions from
libinput-private.h. Having 64 bit timestamps has no use past this point,
since the wayland input protocol uses 32 bit timestamps (and clients will
have to deal with wrapping).

10 years agotouchpad: Rework is_pointer handling
Hans de Goede [Fri, 4 Apr 2014 15:22:02 +0000 (17:22 +0200)]
touchpad: Rework is_pointer handling

We don't want touches in the button area to cause the pointer to move. So
instead of making a touch the pointer when it moves to TOUCH_BEGIN, wait
with making it the pointer until its buttons state moves to BUTTON_STATE_AREA.

Note that a touch in the main area of the touchpad will move to
BUTTON_STATE_AREA immediately. If software-buttons are not enabled, any finger
is in the BUTTON_STATE_AREA.

While at it also refactor the is_pointer setting in general, removing
code duplicition wrt checking that another touch is not already
the pointer on unpinning a finger, and add safeguards that unpinning
does not make a finger which is not in button state BUTTON_STATE_AREA the
pointer, nor that the button code makes a pinned finger the pointer.

All these sanity checks are combined into a new tp_button_active function,
since they should be taken into account for 2 finger scrolling, etc. too.

10 years agotouchpad: Add clickpad-style software buttons
Peter Hutterer [Thu, 27 Mar 2014 23:44:11 +0000 (09:44 +1000)]
touchpad: Add clickpad-style software buttons

Almost all non Apple touchpads have visible markings for software button areas,
so limit clickfinger behavior to Apple clickpads, and implement software button
areas for others.

This is a slightly fancier implementation than the simplest model and ported
over from libtouchpad. It implements a state machine for the software buttons
with left and right buttons currently implemented. Buttons are oriented
left-to-right, in a horizontal bar. No random button placement allowed.

In general, the procedure is:
- if a finger sets down in the left button area, a click is a left click
- if a finger sets down in the right button area, a click is a right click
- if a finger leaves the button area, a click is a left click
- if a finger starts outside the button area, a click is a left click

Two timeouts are used to handle buttons more smoothly:
- if a finger sets down in a button area but "immediately" moves over
  to a different area, that area takes effect on a click.
- if a finger leaves a button area and "immediately" clicks or moves back into
  the area, the button still takes effect on a click.
- if a finger changes between areas and stays there for a timeout, that area
  takes effect on a click.

Note the button area states are named BOTTOM_foo to make it easier to later
add support for a top button area such as can be found on the Thinkpad [2-5]40
series.
