Subject: [PATCH v2 0/3] Add support for frequency invariance to AMD EPYC Zen2
Date: Tue, 10 Nov 2020 19:30:51 +0100 [thread overview]
Message-ID: <20201110183054.15883-1-ggherdovich@suse.cz> (raw)
v1 at https://lore.kernel.org/lkml/20201110083936.31994-1-ggherdovich@suse.cz/
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
arch/x86/include/asm/topology.h | 8 ++++
arch/x86/kernel/smpboot.c | 84 +++++++++++++++++++++++++++++++--
