Phoronix: AMD P-State Preferred Core Submitted For Linux 6.9 While Intel Meteor Lake Gets Tuned

The in-development Linux 6.9 kernel is finally landing support for AMD Preferred Core as part of the power management updates for this mid-2024 kernel release...

I hope this version of P-State doesn't intensify stuttering in poorly optimized games like previous patchsets did.

Had this issue with Dead Island 2 (and Halo Infinite prior to Mesa 24 + Proton 9)

Hello,

I've noticed that, at least on Linux 6.5.13-5 (Proxmox), my Ryzen 3700X-based system defaults to using the acpi driver, even with the amd-pstate driver enabled in the kernel. I can manually override it via the boot command line, and actually turned on the AMD Pstate driver to see if it would work. It did, both in active and passive mode, but enough of the output and behavior was wonky in active mode that I decided to revert to default and went back to acpi.

By contrast, the same OS installed on an Intel 12500T board had no issue auto-selecting Intel's custom power driver.

Does this patch make it more likely that the AMD pstate driver will be auto-selected in new versions of Linux going forward?
