Since last August AMD Linux engineers have been working on P-State Preferred Core support for the 'amd pstate' driver so that this functionality can be leveraged under Linux for improved task placement.
While not quite as exciting as yesterday's AMD XDNA driver publishing for Ryzen AI on Linux, a notable patch series out of AMD today on the Linux front is enabling AMD Core Performance Boost controls within their P-State CPU frequency scaling driver.
For the past number of months AMD has been actively working on enabling AMD P-State Preferred Core functionality for Linux so that their modern processors can communicate 'preferred' cores to the Linux kernel scheduler for making better decisions around task placement and ultimately ensuring best performance of Ryzen and EPYC processors running on Linux
