I implemented this patch against releng/10.3 so that I could use it on my
laptop. It seems to work without incident.
I don't know how to make a unified diff, so I will link the github repo where I
stored the changes.

Patch updated to apply cleanly against 11-current (r301929)
Hi Raphael, thank you very much for your work on this!
I have gone through this patch line by line and modified it to apply cleanly to
11-current as of r301929.
I will rebuild my kernel+world now and do some testing.

Attachment #164815|Combined back-port from |Patch to add Elantech
description|11-CURRENT psm + Elantech |support to 10-STABLE
|support patch |(r292841)
bugzilla...@freebsd.org
--- Comment #3 from Ben Woods <wood...@freebsd.org> ---
I can confirm that this patch against 11-current compiles and allows my
Elantech trackpad to work if I add the following line to /boot/loader.conf and
reboot:
hw.psm.elantech_support="1"
Two-finger scrolling works perfectly by default.
One interesting behaviour is click+drag does not work as expected. If I click
in the bottom left of the trackpad with one finger, and use a different finger
to drag on the track pad, I expect it to select the text from the start to
finish of the drag motion. Instead the cursor remains still on the screen and
it enables scroll action as I drag. I can still click+drag successfully using
another technique: double tap (touch) and drag with the one finger.

The only differences to Vladimir's original patch are those required to make it
apply cleanly to 11-current (r301929).

Hi, all
Here is up to date version of patch from my private repository. It is
simplified version of previous patch as I changed direction of development and
now use evdev interface for direct reporting of absolute fingers position to
libinput or xf86-synaptics driver (evdev part is not included here). So for
most people this patch will not make life better as compared with previous
version :-(
Most notable changes are:
1. Dirty "Multitouch" hack has been removed. For now only first finger position
is accounted for 2 finger scroll
2. (Unested) Ver 2. Hardware initialization sequence changed to match OpenBSD
not Linux (linux guys did not commit that part for unknown reason)
3. HW Ver 3 2finger touch is processed as single 12-byte packet not as 2
6-bytes packets. (Libinput wants this)
4. diff size has been reduced
5. Something else that I cant remember.
Not all of these changes has been tested due to lack of hardware so
regressions are possible.

Hi Vladimir,
Thanks for the update. I have tested it and confirm that it still allows me to
have working two-finger scrolling, even without the evdev work. I do still have
a problem with click-and-drag.
Thanks for your work on this.

Thanks for testing, Ben!
Click and drag is not supported. It is a restriction of single-touch gesture
processor dated back to 2008 and r183888. Single-double-triple tap and drag
only.
It`s possible to add a hack to simulate this but i think it is a wrong way. IMO
the right way is to move gesture processing to one of already existing userland
library and leave current code path in its current state to vt & sc mouses
only.
bugzilla...@freebsd.org
--- Comment #9 from Ben Woods <wood...@freebsd.org> ---
Hi Vladimir,
I am not convinced that click and drag only needs support in X, and therefore
doesn't need to be in the psm(4) driver. In fact, if I disable the elantech
support with this patch, click and drag is support with the moused generic 3
button mouse support. Enabling the elantech support breaks click and drag, but
it would be handy to use in both the console and in X (for copying).

(In reply to Vladimir Kondratyev from comment #11)
Thanks for that - it works very nicely! It works as long as I click before
touching my other finger to the touchpad. However, if I happen to have my other
finger already resting on the touchpad then it still doesn't work, and
sometimes tries to scroll. Is it possible to make the click take precedence and
cancel any current multitouch action?
bugzilla...@freebsd.org
--- Comment #14 from Vladimir Kondratyev <wu...@cicgroup.ru> ---
(In reply to Ben Woods from comment #13)
This behaviour is expected. Gesture processor is single-touch only, so driver
tries to predict which finger will move and sometimes does it wrong.
I tried to split current code on separate movement smoother and gesture
processor parts to be able to use 2 instances of smoother and track both
fingers at one time but some regressions appeared. I will post updated patch
here if I fix them but can say nothing about timeframe

Adrian / Vladimir: what are your thoughts about whether this could make it into
FreeBSD 11? Is it too late now that we are in code/ABI freeze?
bugzilla...@freebsd.org
--- Comment #18 from Ben Woods <wood...@freebsd.org> ---
Not sure if it helps to say that the majority of this code only take effect if
the following sysctl is set at boot time:

This patch requires regression testing on synaptics touchpads and I do not have
such hardware.

I've been running an early version of this patch on my laptop with a Synaptics
touchpad with no problem; I'll try the latest version.
Does the multitouch functionality extend to the Synaptics variant of psm(4)?

with a synaptics touchpad for regression testing purposes?
Maybe we could now land this driver in 12-current?
Adrian: would you be willing to have a look, as previously mentioned?

I have tested the patch on two Lenovo laptops which have Synaptics (ThinkPad
S440) and Elantech (S20-30) trackpads. I already had Synaptics support with the
psm(4) driver and the patch doesn’t seem to introduce regressions.
What I have tested, both on console and X:
- Select / Copy / Paste with tap, drag and three-finger tap.
- Two-finger scroll.
- Normal button operation.
Hope it helps,
Juan

HW version 3 can be considered as basicaly working. Thanks

Here is harmless bug in driver. HWv3 is multitouch TP not semi-multitouch. I
will fix that
Could you do following gestures and post results here:
Gest 1.
1. Put first finger on e.g. left bottom corner of TP
2. Do a short move so cursor moves too
3. Put second finger on opposite corner
4. Move both fingers to trigger 2finger scroll
5. Release first (left) finger but leave second on TP
6. Move second finger across TP
Gest 2.
1 - 4 is the same
5. Release second (right) finger but leave first on TP
6. Move first finger across TP
Does cursor jump on p.5?
What is happening on p.6? Cursor moving or scrolling?
Could you post synaptics "dmesg" and "sysctl hw.psm." output here too?
