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 arch/x86/include/asm/topology.h | 8 ++++ arch/x86/kernel/smpboot.c | 84 +++++++++++++++++++++++++++++++-- drivers/acpi/cppc_acpi.c | 3 ++ 3 files changed, 90 insertions(+), 5 deletions(-) -- 2.26.2
