Subject[PATCH v2] cpufreq: intel_pstate: Add Icelake servers support in no-HWP mode
Date
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").
