This solves Debian Bug report 1008760:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1008760.
Solution was inspired by this kernel bug report message:
https://bugzilla.kernel.org/show_bug.cgi?id=204967#c15.
My measured pad dimensions with a ruler were 85x44mm.
But I decided to take the 2x size reported by the current kernel
when invoking the touchpad-edge-detector command from the
libdev-tools package. Because this comment claims that the old
vs new kernel reportings differ by factor 2:
https://bugzilla.kernel.org/show_bug.cgi?id=204967#c3 .
Therefore I have used this command to get the new entry to 60-evdev.hwdb:
"root@pb:~# touchpad-edge-detector 80x34 /dev/input/event2
Touchpad ETPS/2 Elantech Touchpad on /dev/input/event2
Move one finger around the touchpad to detect the actual edges
Kernel says: x [0..1254], y [0..528]
Touchpad sends: x [0..2472], y [-524..528] -^C
Touchpad size as listed by the kernel: 40x17mm
User-specified touchpad size: 80x34mm
Calculated ranges: 2472/1052
Suggested udev rule:

This fixes the discrepancies in the coordinate ranges for the touchpad, touchpad in this device(NS13A2) is generic and the same one is used in most models.
We've had this text since the beginning, but in fact the patterns must be
stable in order for people to create local hwdb entries. And we support that
and can't change the match patterns without being very careful. So let's just
drop the text.
The Pinebook Pro touchpad returns a resolution data that is 2 times of
the real value, which makes libinput think the touchpad is only 1/4 the
real size.
Add a resolution override value for it, to allow libinput to calculate
the distance moved on it correctly.

This reverts commit c0443b97b7.
I got various cases wrong:
"usb:v04F3p2B7Cd5912dc00dsc00dp00ic03isc00ip00in00"
"usb:v0627p0001:QEMU USB Tablet"
"input:b0003v0627p0001e0001-e0,1,2,4,k110,111,112,r0,1,8,B,am4,lsfw"
OTOH:
-evdev:name:ETPS/2 Elantech Touchpad:dmi:*svnASUSTeKComputerInc.:pnN53SV:*
+evdev:name:ETPS/2 Elantech Touchpad:dmi:*svnASUSTeKComputerInc.:pnN53SV*
is OK. Other parts follow after 'pn'.
-mouse:*:name:*Trackball*:*
-mouse:*:name:*trackball*:*
-mouse:*:name:*TrackBall*:*
+mouse:*:name:*Trackball*:
+mouse:*:name:*trackball*:
+mouse:*:name:*TrackBall*:
... and anything else with :name should be OK too, because our imports always
include ":" at the end:
IMPORT{builtin}="hwdb 'joystick:$env{ID_BUS}:v$attr{id/vendor}p$attr{id/product}:name:$attr{name}:'"
Including '*' at the end makes the pattern work even if we decide to add
something to the match string later.
Fixes#17499.
No functional change is intended.
The general pattern of changes:
-usb:v04F3p2B7C*
+usb:v04F3p2B7C:*
This is mostly a clarification, to make the part that makes the usb vXXXXpYYYY
part visually separated. It would only make a difference if we added further
keys with a different number of digits, which is unlikely.
-usb:v0627p0001:*QEMU USB Keyboard*
-usb:v0627p0001:*QEMU USB Mouse*
-usb:v0627p0001:*QEMU USB Tablet*
+usb:v0627p0001:*QEMU USB Keyboard*:*
+usb:v0627p0001:*QEMU USB Mouse*:*
+usb:v0627p0001:*QEMU USB Tablet*:*
Again, only a clarification. We know that ":" will appear somewhere later in
the match key, so anything that matches "…Keyboard*" will also match "…Keyboard*:*".
-evdev:name:ETPS/2 Elantech Touchpad:dmi:*svnASUSTeKComputerInc.:pnN53SV*
+evdev:name:ETPS/2 Elantech Touchpad:dmi:*svnASUSTeKComputerInc.:pnN53SV:*
This makes the match narrower. Previously we would match product "N53SV"
and "N53SV2", "N53SV3", and others. Here we are saying that the ':pn' part must
match exactly. Most of the changes in this patch match this pattern. I made a few
judgement calls and used "pn…*:*" when I wasn't sure if the full pn is included:
-evdev:name:Dell WMI hotkeys:dmi:bvn*:bvr*:bd*:svnDell*:pnPrecision*
+evdev:name:Dell WMI hotkeys:dmi:bvn*:bvr*:bd*:svnDell*:pnPrecision*:*
-evdev:name:Cypress APA Trackpad ?cyapa?:dmi:*:svnHewlett-Packard*:pnFalco*:
+evdev:name:Cypress APA Trackpad ?cyapa?:dmi:*:svnHewlett-Packard*:pnFalco*:*
This more like the "QEMU" example above, since all dmi strings end in ":", so
anything which matches the old version will also match the new version.
-evdev:atkbd:dmi:bvn*:bvr*:bd*:svnGateway*:pnA0A1*:pvr*
+evdev:atkbd:dmi:bvn*:bvr*:bd*:svnGateway*:pnA0A1*:*
I replaced trailing ":pvr*" by ":*". This makes no functional difference because
we expect "pvr" to always appear in the dmi string. This makes patterns shorter.
-evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn*
+evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn*:*
OTOH, ":pn*" is kept. This is because almost patterns include ":pn*", and if we
skip it, we should make it clear that this is on purpose, that we really want to
match any product name.
The python script to generate autosuspend rules is updated to use ":*" too.

As discussed in https://gitlab.freedesktop.org/libinput/libinput/-/issues/521, it adds a narrower
match that only applies to X240. Other laptops that match `pvrThinkPad??40` are not affected:
$ systemd-hwdb query 'evdev:name:SynPS/2 Synaptics TouchPad:dmi:*svnLENOVO*:pvrThinkPadX240:*'
EVDEV_ABS_00=1232:5711:51
EVDEV_ABS_01=1159:4700:53
EVDEV_ABS_35=1232:5711:51
EVDEV_ABS_36=1159:4700:53
$ systemd-hwdb query 'evdev:name:SynPS/2 Synaptics TouchPad:dmi:*svnLENOVO*:pvrThinkPadX140:*'
EVDEV_ABS_00=::41
EVDEV_ABS_01=::37
EVDEV_ABS_35=::41
EVDEV_ABS_36=::37
The original source of these dimensions had swapped the x y dimension
arguments to touchpad-edge-detector. The correct dimensions are
x = 100 mm, y = 68 mm
Add the resolution and range information for Lenovo Ideapad 310S-14ISK Alps touchpad. It provides information for the test case of libinput for Alps devices.
The Synaptics Touchpad that comes with the T490 doesn't explicitly set
its resolution, so these lines are needed to provide that, in order to
help the libinput code detect overly large jumps. Since this device
contains buttons under the lower section of the touchpad, large jumps
are common, so having the resolution helps libinput greatly reduce
the number of occurances of pointer jump.
