This commit adds a rules file to extract the properties from hwdb
to set on i2c IIO devices. This is used to set the ACCEL_MOUNT_MATRIX
property on IIO devices, to be consumed by iio-sensor-proxy or
equivalent daemon.
The hwdb file contains documentation on how to write quirks. Note
however that mount information is usually exported in:
- the device-tree for ARM devices
- the ACPI DSDT for Intel-compatible devices
but currently not extracted by the kernel.
Also note that some devices have the framebuffer rotation that changes
between the bootloader and the main system, which might mean that the
accelerometer is then wrongly oriented. This is a missing feature in the
i915 kernel driver: https://bugs.freedesktop.org/show_bug.cgi?id=94894
which needs to be fixed, and won't require quirks.

The main purpose of this hwdb was to tag touchpads that have the physical
trackstick buttons wired to the touchpad (Lenovo Carbon X1 3rd, Lenovo *50
series). This hwdb is not required on kernels 4.0 and above, the kernel now
re-routes button presses through the trackstick's device node. Userspace does
not need to do anything.
See kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c.
This reverts commit 001a247324b44c0e0b8fdba41a6fc66e7465b8b6.

It is not udev's task to apply any of these setting that way, or
from udev rules files. Things need to be sortet out in the kernel,
or explicit whitelist can possibly be added to the hardware database.
Until that is sorted out, and general agreement, udev is not
willing to maintain any such lists or power management settings
in general.
"Thanks for digging this out! I thought my Kinesis keyboard got broken
and ordered a new one, only to find out that the new one doesn't work
as well. I'm not sure whether we should start collecting a blacklist
of keyboards which don't work with USB autosuspend, or rather a
whitelist? Or revert this wholesale?"

Parse properties in the form
EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>"
and apply them to the kernel device. Future processes that open that device
will see the updated EV_ABS range.
This is particularly useful for touchpads that don't provide a resolution in
the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974).
All values in the property are optional, e.g. a string of "::45" is valid to
set the resolution to 45.
The order intentionally orders resolution before fuzz and flat despite it
being the last element in the absinfo struct. The use-case for setting
fuzz/flat is almost non-existent, resolution is probably the most common case
we'll need.
To avoid multiple hwdb invocations for the same device, replace the
hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules
file. The new 60-evdev.rules is called for all event nodes
anyway, we don't need a separate rules file and second callout to the hwdb
builtin.

Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon
3rd. These laptops re-introduced the physical trackpoint buttons that were
missing from the *40 series but those buttons are now wired up to the
touchpad.
The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same
button codes were used in older touchpads that had dedicated scroll up/down
buttons. Input drivers need to work around this and thus know what they're
dealing with.
For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but
the resulting mess showed that these per-device quirks should really live in
userspace.
The list currently includes the X1 Carbon 3rd PNPID, others will be added as
get to know which PNPID they have.

Pointer acceleration for relative input devices (mice, trackballs, etc.)
applies to the deltas of the device. Alas, those deltas have no physical
reference point - a delta of 10 may be caused by a large movement of a
low-dpi mouse or by a minute movement of a high-dpi mouse.
Which makes pointer acceleration a bit useless and high-dpi devices
essentially unusable.
In an ideal world, we could read the DPI from the device directly and work
with that. In the world we actually live in, we need to compile this list
manually. This patch introduces the database, with the usual match formats
and a single property to be set on a device: MOUSE_DPI
That is either a single value for most mice, or a list of values for mice
that can change resolution at runtime. The exact format is detailed in the
hwdb file.
Note that we're explicitly overshooting the requirements we have for
libinput atm. Frequency could be detected in software and we don't
actually use the list of multiple resolutions (because we can't detect
when they change anyway). However, we might as well collect those values
from the get-go, adding/modifying what will eventually amount to hundreds
of entries is a bit cumbersome.
Note: we rely on the input_id builtin to tag us as mouse first, ordering
of the rules is important.
(David: fixed up typos and moved hwdb file into ./hwdb/)

This commit imports the new internal keyboard handling from upstream.
This is a combination of many upstream commits, including those
that added code, removed old code, and updated the hwdb.
Some commits (hwdb ones specifically) were unrelated but brought
in anyways to keep the whole hwdb consistent. Each upstream
commit included is as follows:

ce39bb6909578017aa10031638e724e038f0b859 - hwdb: data update, upstream
884c86812c51479496edd50b278383d7bb67baf0 - rules: keyboard - use builtin command
All code from each of the above commits is attributed to the original
authors.
There were some adjustments made in order to support the code differences
between upstream and eudev, which was done by myself.
Also of note is that the code can still be disabled via the --disable-keymaps
configure option, which was removed from upstream.

This sets the permissions on null, zero, full, random and urandom
to 666 which is needed for older kernels. This is part of Gentoo's
40-gentoo.rules which can now be dropped from Gentoo's ebuild.

We move the test-udev.c and test-libudev.c from src/test to test.
This corrects the a problem with hard coded relative paths finding
the test/test/sys directory created by test/udev-test.pl.

The configuration of the installation paths for various components
was scattered between the main configure.ac file and the various
Makefile.am's. These components are: udev config file, hwdb, keymaps
and force-release keymaps and the rules. This commit consolidates
them all into one point in configure.ac and anticipates the inclusion
of new AM_CPPFLAGS of the form -DHWDB_BIN=@udevhwdbdir@ as upstream
has done, so it is easier to address issues like:

${rootlibdir}/udev instead of ${root}/lib/udev
|
|
|
|
The structure of the source tree is basically correct and this is
about as far as we can go without hacking at the C code.
|
|
The original Makefile.am was drawn to the top level. This commit
breaks it out into the various directories with SUBDIRS connecting
them. This makes each directory easier to maintain.
