3 Kernel driver aquacomputer-d5next
4 =================================
8 * Aquacomputer D5 Next watercooling pump
9 * Aquacomputer Farbwerk RGB controller
10 * Aquacomputer Farbwerk 360 RGB controller
11 * Aquacomputer Octo fan controller
12 * Aquacomputer Quadro fan controller
19 This driver exposes hardware sensors of listed Aquacomputer devices, which
20 communicate through proprietary USB HID protocols.
22 For the D5 Next pump, available sensors are pump and fan speed, power, voltage
23 and current, as well as coolant temperature. Also available through debugfs are
24 the serial number, firmware version and power-on count. Attaching a fan to it is
25 optional and allows it to be controlled using temperature curves directly from the
26 pump. If it's not connected, the fan-related sensors will report zeroes.
28 The pump can be configured either through software or via its physical
29 interface. Configuring the pump through this driver is not implemented, as it
30 seems to require sending it a complete configuration. That includes addressable
31 RGB LEDs, for which there is no standard sysfs interface. Thus, that task is
32 better suited for userspace tools.
34 The Octo exposes four temperature sensors and eight PWM controllable fans, along
35 with their speed (in RPM), power, voltage and current.
37 The Quadro exposes four temperature sensors, a flow sensor and four PWM controllable
38 fans, along with their speed (in RPM), power, voltage and current.
40 The Farbwerk and Farbwerk 360 expose four temperature sensors. Depending on the device,
41 not all sysfs and debugfs entries will be available.
46 The devices communicate via HID reports. The driver is loaded automatically by
47 the kernel and supports hotswapping.
