AMD Brings Ryzen Overclocking Driver to Linux

AMD has published Linux kernel patches for an official Ryzen overclocking driver that allows users to adjust CPU power and current limits through a firmware interface exposed via sysfs. Phoronix reports: AMD engineer Shyam Sundar S K posted the patches for the AMD Overclocking "AOD" WMI driver as an interface to the platform firmware for managing overclocking and power/current limits of modern…

AMD has officially published new patches for the Linux kernel that bring Ryzen overclocking to the Linux operating system. This development allows Linux users to adjust CPU tuning without having to delve into the opaque firmware settings typically used on Windows. The new kernel driver, known as AOD (AMD Overclocking Driver), provides a direct pipeline to AMD's platform adjustments, exposing core tuning capabilities through the standard sysfs interface.

This means that users can now easily toggle Simultaneous Multithreading (SMT), monitor memory clocks, and control power settings through clean kernel sysfs nodes. While AMD is following its open-source amdgpu graphics driver playbook and leaving the user-space presentation layer to the community, the new patches are currently being reviewed for mainstream kernel integration.

This marks a significant milestone for Linux enthusiasts who want to optimize their Ryzen processors while maintaining a fully open-source software stack.

  • Modify wp-config.php to define DISABLEWPCRON as true
  • Use WP Crontrol plugin to verify tasks are running on time

I re-verified 30 disclosed Supabase keys. 20% were still live. The uncomfortable finding: developers who thank you for reporting a leaked key — and swear they rotated it — often don't.

  • Cenk Kurtoglu disclosed 30 Supabase servicerole keys
  • 20% of keys were still live after initial disclosure
  • Kurtoglu offers key rotation verification service
