Dear all, I have found an issue with the patchset when applying on 6.7, leading to a large degradation in performance. On my 7840HS on *STOCK* 6.7 highest_perf is reported as 196, not 166 as assumed in the patchset. Applying the patchset causes highest_perf to be misreported and hence a misrepo

[PATCH V14 0/7] amd-pstate preferred core

2024-01-19 Thread Meng Li
Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach
