Subject: [PATCH v2] cpufreq: intel_pstate: Add Icelake servers support in no-HWP mode
Date: Thu, 13 May 2021 15:20:51 +0200 [thread overview]
Message-ID: <20210513132051.31465-1-ggherdovich@suse.cz> (raw)
In-Reply-To: <fb6c8a4e284a9b6c043f4ac382387b19bd100976.camel@linux.intel.com>
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").
