[PATCH v2] cpufreq: intel_pstate: Add Icelake servers support in no-HWP mode
From: Giovanni Gherdovich <hidden>
Date: 2021-05-13 13:21:39
Also in:
lkml
Subsystem:
cpu frequency scaling framework, intel pstate driver, the rest · Maintainers:
"Rafael J. Wysocki", Viresh Kumar, Srinivas Pandruvada, Len Brown, Linus Torvalds
Users may disable HWP in firmware, in which case intel_pstate wouldn't load
unless the CPU model is explicitly supported.
Add ICELAKE_X to the list of CPUs that can register intel_pstate while not
advertising the HWP capability. Without this change, an ICELAKE_X in no-HWP
mode could only use the acpi_cpufreq frequency scaling driver.
See also commit d8de7a44e11f ("cpufreq: intel_pstate: Add Skylake servers
support").
