While advertising three profiles, they do not change anything. See https://forums.lenovo.com/t5/Other-Linux-Discussions/T14-AMD-subpar-CPU-per= formance/m-p/5089829?page=3D1#5386521 for details. As some user space software (e.g. platform-profiles-daemon) expects them to work correctly when they are available, they should not be exported for bro= ken devices. Therefore, I suggest to stop exporting a platform_profile interface for the Lenovo T14/P14s Gen2 AMD. --=20 You may reply to this email to add a comment.
