Ivy Bridge uses separate power wells managed via ACPI:
Let’s dissect the keyword into its semantic tokens: acpi genuineintel---intel64-family-6-model-58
In Linux kernel source code (specifically in arch/x86/kernel/cpu/intel.c and drivers/acpi/processor_driver.c), this string is generated when the ACPI processor driver matches a detected CPU against its internal tables. It is not an error; it is a debug or identification token used to apply model-specific quirks and power management policies. Ivy Bridge uses separate power wells managed via
