AMD Enhances Linux Drivers for Anticipated Zen 5 Ryzen 9000 CPUs

Summary:

  • Improved power management capabilities for Ryzen APUs
  • Efficient handling of S2Idle transactions for popular models like Renoir, Cezanne, Rembrandt, and Phoenix
  • Continued commitment to the Linux community and optimization of drivers for upcoming processors


AMD has recently made an exciting development for Linux users and enthusiasts. The company has enhanced its Linux PMC driver to include initial support for the highly anticipated Ryzen 9000 “Zen 5” processors. This update is a significant step forward in preparing for the release of the Zen 5 family, also known as Family 26 (1Ah) processors.

The AMD PMC driver, which is part of the SoC power management controller driver, is now equipped to handle the power management controller on Ryzen APUs. This includes popular models like Renoir, Cezanne, Rembrandt, and Phoenix. The driver manages S2Idle transactions initiated by the platform firmware on the SMU, ensuring efficient power management for these processors.

It’s worth noting that this update primarily focuses on mobility and embedded processors, meaning that desktop CPUs remain unaffected. While AMD hasn’t explicitly confirmed that Family 1Ah refers to Zen 5, tech publication Phoronix has expressed confidence in its reporting.

What’s particularly impressive about this development is that it required only six patches, affecting just two dozen lines of code. Despite this minimal impact, the enhanced Linux PMC driver now supports the upcoming Zen 5 processors without revealing any additional information about them.

This news is undoubtedly exciting for Linux users who are eagerly awaiting the release of the Ryzen 9000 series. With AMD’s continued commitment to improving their Linux drivers, it’s clear that they value their Linux user base and want to ensure a seamless experience for them.

As we approach the New Year, it’s expected that more details about the Zen 5 processors will emerge. Until then, Linux enthusiasts can take solace in knowing that AMD is diligently working to optimize their drivers for these highly anticipated CPUs.

In conclusion, AMD’s recent enhancement of its Linux PMC driver to support the upcoming Zen 5 processors is a promising development for Linux users. With improved power management capabilities and continued commitment to the Linux community, AMD is solidifying its position as a leading choice for enthusiasts and professionals alike. As we eagerly await the release of the Ryzen 9000 series, it’s clear that AMD is dedicated to delivering exceptional performance and compatibility for Linux users.
