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

[Giovanni Gherdovich]

v1 at https://lore.kernel.org/lkml/20201110083936.31994-1-ggherdovich@xxxxxxx/

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
