Re: Linux 6.15.5

Hi,

upgrading from linux kernel 6.14.9 to 6.15.2 and also now with 6.15.5 I noticed that on my system with cpufreq scaling driver amd-pstate the frequencies cpuinfo_min_freq and cpuinfo_max_freq increased, the min from 400 to 422.334 MHz, the max from 4,673 to 4,673.823 MHz. The CPU is an AMD Ryzen 7 5700G. This in turn increases other values (scaling_min_freq, scaling_max_freq, amd_pstate_lowest_nonlinear_freq, etc.).

Bisecting this leads to

Did you notice the increase at AMD? Is it intended?

Thanks, Jörg.
