Acpi Genuineintel---intel64-family-6-model-58 Guide
Here’s a breakdown of what that string means, followed by content you can use for documentation, a blog post, a system report, or a troubleshooting guide.
5. Performance and Legacy Status
As of 2024, Family 6 Model 58 (Ivy Bridge) is considered legacy hardware. acpi genuineintel---intel64-family-6-model-58
- Capabilities: It supports PCIe 3.0, USB 3.0 (native on 7-series chipsets), and DDR3 memory.
- Windows 11 Compatibility: These CPUs are not officially supported by Windows 11. The processor model does not appear on Microsoft's compatibility list because it lacks hardware security features like TPM 2.0 (native) and specific architectural protections required by the OS, although users have found workarounds.
- Modern Usage: These CPUs are still capable of basic office work, web browsing, and serving as home servers, but they lack the efficiency and speed of modern 14nm or 10nm/Intel 4/7 architectures.
2.1 Linux kernel ACPI processor registration
When the kernel initializes ACPI, it examines each processor object (\PR_ or _SB_.PRxy). The acpi_processor_get_info() function prints or matches the CPUID against ACPI IDs. You might see similar strings in: Here’s a breakdown of what that string means,

1.2 genuineintel
This is the CPU vendor ID returned by the CPUID instruction (EAX=0). For Intel processors, EBX=0x756e6547 ("Genu"), EDX=0x49656e69 ("ineI"), ECX=0x6c65746e ("ntel"). Concatenated, they spell "GenuineIntel". Capabilities: It supports PCIe 3
The kernel uses this to apply vendor-specific errata, feature detection, and power management policies. When you see genuineintel (often lowercased in logs), it means the system has positively identified an Intel CPU.
