Hi All, Can I on-board to this patch or do you want me to submit another? I want to add COMETLAKE (tested), as below: ... Doug On Thu, May 13, 2021 at 6:21 AM Giovanni Gherdovich [off-list ref] wrote:

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").
