libratbag
|
|
=========
|
|
|
|
libratbag is a configuration library for gaming mice. It provides a generic
|
|
way to access the various features exposed by these mice and abstracts away
|
|
hardware-specific and kernel-specific quirks.
|
|
|
|
Architecture
|
|
------------
|
|
|
|
libratbag has two main components, the front-end API and wrapper code, and
|
|
the back-end HW-specific drivers:
|
|
|
|
+-----+ +-----+ +-----------+ +----------+
|
|
| app | -> | API | -> | hw-driver | -> | protocol | -> device
|
|
+-----+ +-----+ +-----------+ +----------+
|
|
|
|
The API layer is HW agnostic. Depend on the HW, the protocol may be part of
|
|
the driver implementation (e.g. etekcity) or a separate set of files
|
|
(HID++). Where the protocol is separate, the whole known protocol should be
|
|
implemented. The HW driver then only accesses the bits required for
|
|
libratbag. This allows us to optionally export the protocol as separate
|
|
library in the future, if other projects require it.
|
|
|
|
Adding Devices
|
|
--------------
|
|
|
|
As of commit 3605bede4 libratbag now uses a hwdb entry to match the device
|
|
with the drivers. To access a device through libratbag, the udev property
|
|
RATBAG_DRIVER must be set for a device's event node. Check with
|
|
|
|
sudo udevadm info /sys/class/input/eventX | grep RATBAG_DRIVER
|
|
|
|
If your device is not yet assigned the property, it is not in the hwdb. It
|
|
may however be supported by one of our existing drivers. Try enabling it by
|
|
adding the device vendor-id/product-id to the hwdb file in
|
|
`hwdb/70-libratbag-mouse.hwdb`. For example, for a HID++ 1.0 device, edit
|
|
the 70-libratbag-mouse.hwdb file and add an entry with `RATBAG_DRIVER=hidpp10`.
|
|
For the other drivers, look for the id of the driver in driver-{drivername}.c
|
|
file and do the same.
|
|
|
|
Once your device is added to the hwdb, install libratbag and trigger a hwdb
|
|
update:
|
|
|
|
sudo udevadm hwdb --update
|
|
sudo udevadm control --reload
|
|
|
|
Then unplug/replug your mouse. `RATBAG_DRIVER` should appear in the udev
|
|
properties of your device with the value you previously set. If the property
|
|
is not assigned, the hwdb entry does not correctly match your device or the
|
|
installed udev rules/hwdb entries are not picked up by udev.
|
|
|
|
If the device doesn't work, you'll have to start reverse-engineering the
|
|
device-specific protocol. Good luck :)
