AMD brings official Ryzen overclocking to Linux with AOD driver support

While Windows overclockers have spent years lazily sliding UI controls to adjust frequency curves and tweak voltages inside Ryzen Master, Linux users have largely had to treat their CPU tuning like an archaeological dig into the opaque veil of UEFI/BIOS firmware. Well, rejoice, Linux users, as AMD has officially published a fresh set of patches for the Linux kernel introducing AOD (AMD Overclocking Driver) support for Ryzen processors, Phoronix reports.

Instead of forcing developers to reverse-engineer closed-source firmware hooks or rely on messy, machine-specific ACPI workarounds, this new kernel driver is a direct pipeline to AMD's platform adjustments. By exposing core tuning capabilities straight through the standard sysfs interface, AMD is laying down an official, upstreamed foundation for software-level CPU management.

Right out of the gate, the driver handles platform-level SMT toggling, memory clock visibility, and power tunables. That's right: you can now toggle Simultaneous Multithreading (SMT) dynamically through this driver interface. …
