yuazhe commented 4 months ago

This issue happens once again, although CONFIG_INTEL_PMC_CORE=m had been set, the kernel doesn't load intel_pmc_core_pltdrv.ko, and the initstate file is missed as expected. https://www.kernelconfig.io/config_intel_pmc_core?arch=x86&kernelversion=6.9.3 the kernel documentation indicates this config may or may not load intel_pmc_core_pltdrv.ko
