This commit adds complete (with the exception of LEDs and a few other
small things) support for configuring the G.Skill Ripjaws MX780. So far
this has been tested on firmware versions 19 and 21, and both of them
seem to work perfectly with this.
Changes since v1:
- Lots of style fixes
- Remove reset hook, comment out with #if 0 in case of usage in the
future
- Add ret = -EAGAIN check in the loop in gskill_general_cmd()
- Explain why we wait longer then the spec says to in
gskill_general_cmd()
- Check that buf[0] is set to GSKILL_GENERAL_CMD in gskill_general_cmd()
- Add some notes as to why we don't use gskill_general_cmd() in
gskill_select_profile()
- Cleanup return codes, change gskill_general_cmd() so it only returns
valid error codes. In places not using gskill_general_cmd(), do
return rc < 0 ? rc : -EPROTO;
- Split command for selecting the macro to read/write from into it's own
function, just like we do with the profile
- Move profile count workaround into it's own function, make explicit
note of why it's needed
- Add proper support for reading/writing profile/macro names, ensure
they aren't left blank so as to not confuse G.Skill's software
- Use HID kbd modifier codes for translating macro kbd modifier codes
- Use AS_MASK instead of (1 << foo) (apparently we already had this :)

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.
Documentation
API documentation is available here:
http://libratbag.github.io/libratbag/
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 :)
