These instruction are made with a Nintendo Pro controller and Joy-Cons. While the overall process will be the same the motion axis may not match those found on a Sony DualShock 4.
Dolphin supports the motion [https://en.wikipedia.org/wiki/Evdev evdev] devices but setting it up is a bit awkward. Nintendo Switch controllers (Joy-Con and Pro controller) are supported through the hid-nintendo driver. Sony DualShock 4 and DualSense through hid-sony/hid-playstation.


* Recent dolphin version (do not use 5.0 stable!)
The HID kernel driver exposes 2 (or more) evdev devices, one for the buttons and another for the accelerators/gyroscopes. The hid-nintendo driver exposes the motion axis on an "IMU" device while hid-playstation named it "Wireless Controller Motion Sensors". Do note that Nintendo Joy-Cons will have 2 devices each (4 in total).
* HID Nintendo kernel driver (dkms https://github.com/nicman23/dkms-hid-nintendo)
* Switch pro or Joy-Con.

You may need to add the users to a specific group to be allowed access. On Arch Linux this group is ''input''.
 
It took me a bit of time figuring out which axis corresponds with the right motion control in dolphin.


It took me a bit of time figuring out which axis corresponds with the right motion control in Dolphin. '''These axis might change in the future when evdev standardizes them.

Select the corresponding Accel or Gyro axis, select it and click ok. For example for "Accel Up" in dolphin you need to select "Accel Z+". The end result should look like below.
