SPDX-License-Identifier: GPL-2.0-or-later + +Kernel driver aquacomputer-d5next +================================= + +Supported devices: + +* Aquacomputer D5 Next watercooling pump + +Author: Aleksa Savic + +Description +----------- + +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. + +Usage notes +----------- + +The pump communicates via HID reports. The driver is loaded automatically by +the kernel and supports hotswapping. + +Sysfs entries +------------- + +============ ============================================= +temp1_input Coolant temperature (in millidegrees Celsius) +fan1_input Pump speed (in RPM) +fan2_input Fan speed (in RPM) +power1_input Pump power (in micro Watts) +power2_input Fan power (in micro Watts) +in0_input Pump voltage (in milli Volts) +in1_input Fan voltage (in milli Volts) +in2_input +5V rail voltage (in milli Volts) +curr1_input Pump current (in milli Amperes) +curr2_input Fan current (in milli Amperes) +============ ============================================= + +Debugfs entries +--------------- + +================ =============================================== +serial_number Serial number of the pump +firmware_version Version of installed firmware +power_cycles Count of how many times the pump was powered on +================ =============================================== |
