AMD brings official Ryzen overclocking to Linux with AOD driver

AMD has published Linux kernel patches adding AOD (AMD Overclocking Driver) support for Ryzen CPUs. The driver exposes SMT toggling, memory clock monitoring and initial power controls via sysfs, leaving user-space tools to the community.

• AOD driver exposes Ryzen tuning through standard sysfs interface
• SMT can be toggled dynamically without the nosmt boot parameter
• Memory clock monitoring and initial power controls are included
• Patches are under kernel mailing list review; GUI left to community
