Specifically, it resolves problems related to calculating the highest performance and frequency on the latest CPUs with preferred cores. Additionally, the patchset includes documentation improvements in amd-pstate.rst, offering a comprehensive guide covering topics such as recommended reboot requirements during driver switching, debugging procedures for driver loading failures. Your feedback and suggestions for improvement are highly appreciated. Please review the patches and provide your valuable input. Thank you. Best regards, Perry.
