Subject: [PATCH v2 0/3] Add support for frequency invariance to AMD EPYC Zen2

v1 at https://lore.kernel.org/lkml/[email protected]/

Changes wrt v1:

- made initialization safe under CPU hotplug.
The function init_freq_invariance_cppc now lets only the first caller
into init_freq_invariance().

Giovanni Gherdovich (2):
x86, sched: Use midpoint of max_boost and max_P for frequency
invariance on AMD EPYC
x86: Print ratio freq_max/freq_base used in frequency invariance
calculations

Nathan Fontenot (1):
x86, sched: Calculate frequency invariance for AMD systems

Hello,

I've sent a V3 at
https://lore.kernel.org/lkml/[email protected]/
which is slightly better than this V2.

Please ignore V2, the V3 submission is the most up-to-date.
Sorry for the noise.
