# Pointingstick const-accel configuration, to make different brand / model
# laptop pointingsticks have the same speed / feel, and per model adjustment
# of the IBM TrackPoint driver's sensitivity setting
#
# The lookup keys are composed in:
#   60-evdev.rules
#
# Note: The format of the "evdev:" prefix match key is a contract between the
# rules file and the hardware data, it might change in later revisions to
# support more or better matches, it is not necessarily a stable ABI.
#
# Supported hardware matches are:
#  - Generic input devices match:
#      evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV
#    This matches on the kernel modalias of the input-device, mainly:
#    ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and
#    WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV
#    is an arbitrary length input-modalias describing the device capabilities.
#
#  - Input driver device name and DMI data match:
#      evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn*
#    <input device name> is the name device specified by the driver,
#    <vendor> is the firmware-provided string from the kernel DMI modalias.
#
# To add local entries, create a new file
#   /etc/udev/hwdb.d/71-pointingstick-local.hwdb
# and add your rules there. To load the new rules execute (as root):
#   udevadm hwdb --update
#   udevadm trigger /dev/input/eventXX
# where /dev/input/eventXX is the pointingstick in question. If in
# doubt, simply use /dev/input/event* to reload all input rules.
#
# If your changes are generally applicable, preferably send them as a pull
# request to
#   https://github.com/systemd/systemd
# or create a bug report on https://github.com/systemd/systemd/issues and
# include your new rules, a description of the device, and the output of
#   udevadm info /dev/input/eventXX
# (or /dev/input/event*).
#
# Allowed properties are:
#   POINTINGSTICK_CONST_ACCEL
#   POINTINGSTICK_SENSITIVITY
#
# Entries should be sorted with growing _SENSITIVITY and _CONST_ACCEL.

#
# Trackpoint const accel settings are specified as
#    POINTINGSTICK_CONST_ACCEL=<accel>
#
# Where <accel> is a floating point number, using a '.' seperator, specifying
# by how much to multiply deltas generated by the pointingstick to get
# normalized deltas.
