[PATCH 00/11] AMD Pstate Driver Fixes and Improvements

[Perry Yuan]

Hello everyone,

This patchset addresses critical issues and enhances performance settings for CPUs
with heterogeneous core types in the AMD pstate driver. 
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.
