is a standard ACPI _HID for a peripheral device. Instead, it is an internal identifier generated by the OS kernel’s ACPI subsystem – specifically used to match CPU power management policies.
In Linux, x86_model = 58 matches INTEL_FAM6_IVYBRIDGE . acpi genuineintel---intel64-family-6-model-58
The OS matches this identifier against the microcode update file ( intel-ucode/06-3a-xx ).
In drivers/acpi/processor_core.c , the function acpi_processor_get_info() does something like: If you're troubleshooting an error, are you seeing
sysctl dev.acpi_cpu | grep model # Look for "dev.acpi_cpu.0.hid"
Let’s parse this identifier into its components. Instead, it is an internal identifier generated by
Let’s examine what the OS does with this ID on a real Ivy Bridge system (e.g., ThinkPad X230 with i5-3320M).
