Kernel driver asus_rog_ryujin
=============================

Supported devices:

* ASUS ROG RYUJIN II 360

Author: Aleksa Savic

Description
-----------

This driver enables hardware monitoring support for the listed ASUS ROG RYUJIN
all-in-one CPU liquid coolers. 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.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
