Available sensors are pump, internal and external +(controller) fan speed in RPM, their duties in PWM, as well as coolant temperature. + +Attaching external fans to the controller is optional and allows them to be +controlled from the device. If not connected, the fan-related sensors will +report zeroes. The controller is a separate hardware unit that comes bundled +with the AIO and connects to it to allow fan control. + +The addressable LCD screen is not supported in this driver and should +be controlled through userspace tools. + +Usage notes +----------- + +As these are USB HIDs, the driver can be loaded automatically by the kernel and +supports hot swapping. + +Sysfs entries +------------- + +=========== ============================================= +fan1_input Pump speed (in rpm) +fan2_input Internal fan speed (in rpm) +fan3_input External (controller) fan 1 speed (in rpm) +fan4_input External (controller) fan 2 speed (in rpm) +fan5_input External (controller) fan 3 speed (in rpm) +fan6_input External (controller) fan 4 speed (in rpm) +temp1_input Coolant temperature (in millidegrees Celsius) +pwm1 Pump duty +pwm2 Internal fan duty +pwm3 External (controller) fan duty +=========== ============================================= diff --git a/Documentation/hwmon/index.rst b/Documentation/hwmon/index.rst index 6f8a4a7524e8..c19f53d9b3ab 100644 --- a/Documentation/hwmon/index.rst +++ b/Documentation/hwmon/index.rst @@ -46,6 +46,7 @@ Hardware Monitoring Kernel Drivers asc7621 aspeed-pwm-tacho asus_ec_sensors + asus_rog_ryujin asus_wmi_sensors bcm54140 bel-pfe diff --git a/MAINTAINERS b/MAINTAINERS index b9906f88c1b7..8fc0ca8e881c 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3181,6 +3181,12 @@ S: Maintained T: git git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git F: drivers/platform/x86/asus-tf103c-dock.c +ASUS ROG RYUJIN AIO HARDWARE MONITOR DRIVER +M: Aleksa Savic <savicaleksa83@gmail.com> +L: linux-hwmon@vger.kernel.org +S: Maintained +F: drivers/hwmon/asus_rog_ryujin.c + ASUS WIRELESS RADIO CONTROL DRIVER M: João Paulo Rechi Vita <jprvita@gmail.com> L: platform-driver-x86@vger.kernel.org diff --git a/drivers/hwmon/Kconfig b/drivers/hwmon/Kconfig index 3904bb297d61..e4b24ad93961 100644 --- a/drivers/hwmon/Kconfig +++ b/drivers/hwmon/Kconfig @@ -301,6 +301,16 @@ config SENSORS_ASC7621 This driver can also be built as a module.
