Acpi Genuineintel---intel64-family-6-model-58 May 2026

The string "ACPI GenuineIntel Family 6 Model 58" looks like a cryptic line of code, but it is actually the digital "birth certificate" for a specific generation of Intel processors. This identifier points to the Ivy Bridge

• Candidates may assume access to common tooling: cpuid, lscpu, dmidecode, iasl, acpidump, dmesg, journalctl, Linux sysfs at /sys/devices/system/cpu, msr tools, i7z, turbostat, powertop.
• Use current ACPI spec excerpts where required (cite section numbers if needed).
• When exact microarchitecture details are required, assume Model 58 belongs to Intel Family 6 Haswell microarchitecture unless candidate justifies alternative mapping.

Part 6: The Future – Will You Still See This String?

As of 2025, Ivy Bridge (Family 6 Model 58) is over a decade old. However, millions of legacy servers, industrial PCs, and embedded systems still run this hardware. Linux kernel maintainers have not removed the debug print because it costs nothing and helps diagnose power regression for old platforms. acpi genuineintel---intel64-family-6-model-58

Newer CPUs (Skylake, Family 6 Model 94; Cascade Lake, Model 85; Alder Lake, Model 151) produce similar strings, e.g.: The string "ACPI GenuineIntel Family 6 Model 58"

1. Core Identifier Breakdown

When an ACPI-compliant OS (like Linux, Windows, or BSD) parses the DSDT/SSDT tables, it reads the _HID (Hardware ID) or _CID (Compatible ID) for the CPU device. The string ACPI0007 is standard, but OEM firmware sometimes uses raw vendor strings. Candidates may assume access to common tooling: cpuid,

• Examples:

  While "Family 6 Model 58" sounds complex, it’s just technical shorthand for a 3rd Gen Intel "Ivy Bridge"
