Kernel driver aquacomputer-d5next¶
- Aquacomputer D5 Next watercooling pump
Author: Aleksa Savic
This driver exposes hardware sensors of the Aquacomputer D5 Next watercooling pump, which communicates through a proprietary USB HID protocol.
Available sensors are pump and fan speed, power, voltage and current, as well as coolant temperature. Also available through debugfs are the serial number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using temperature curves directly from the pump. If it’s not connected, the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical interface. Configuring the pump through this driver is not implemented, as it seems to require sending it a complete configuration. That includes addressable RGB LEDs, for which there is no standard sysfs interface. Thus, that task is better suited for userspace tools.
The pump communicates via HID reports. The driver is loaded automatically by the kernel and supports hotswapping.
