Linux 6.5 Released With AMD P-State EPP Default, USB4 v2, MIDI 2.0 & More Hardware Bits
www.phoronix.com

Linux 6.5 has many great features from the AMD P-State EPP driver default rather than ACPI CPUFreq for Zen 2 and newer supported AMD Ryzen systems, initial USB4 v2 enablement, initial MIDI 2.0 kernel driver work, more Intel hybrid CPU tuning, and a whole lot more.

    Does anyone have a quick ELI5 for the AMD P-state or a link to some good info around it? Seems people are excited about and I’ve been out of the news cycle loop lately.

      From my understanding, the old acpi only allowed for the kernel to request three levels of voltage/frequency on zen2 based CPUs. The new P-state driver allows for finer grain control of the voltage/frequency which may lead to a lower power draw and faster clocks for a given task.
