Subject: [PATCH] cpufreq: intel_pstate: Add Icelake servers support in no-HWP
mode
Git-commit: fbdc21e9b038d00d0d56fa4e0f7701d42ae08f00
Patch-mainline: v5.14-rc1
References: bsc#1185758
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").
