Acpi Genuineintel---intel64-family-6-model-58 File
To understand what this identifier means, we have to break it down into its four distinct components:
However, if this identifier appears prominently in Windows Event Viewer or on a Blue Screen of Death (BSOD), it usually highlights a breakdown in communication between the operating system, the ACPI subsystem, and the processor.
The ACPI standard defines processor performance states (P-states) for active performance and C-states (C-states) for idle power savings to prolong battery life and reduce heat. The operating system uses ACPI tables to understand which C-states a CPU can enter. Your Intel CPU (Family 6, Model 58) works with the kernel's ACPI processor driver to manage these states efficiently. For example, the intel_idle driver in Linux relies on these ACPI mechanisms to manage C-states. The acpi flag present in /proc/cpuinfo indicates your kernel has ACPI power management support for this CPU. acpi genuineintel---intel64-family-6-model-58
This is the returned by the CPUID instruction (EAX=0). For Intel processors, EBX = 0x756e6547 ( "Genu" ), EDX = 0x49656e69 ( "ineI" ), ECX = 0x6c65746e ( "ntel" ). Concatenated, they spell "GenuineIntel" .
Intel categorizes its processors using a "Family," "Model," and "Stepping" system. To understand what this identifier means, we have
Press Windows Key + R , type msinfo32 , and look at the "Processor" field. 2. Troubleshooting ACPI & System Errors
Are you currently experiencing or seeing this specific text in an error message ? Solved: intel graphic update Your Intel CPU (Family 6, Model 58) works
: Refers to the microarchitecture family. Nearly all modern Intel processors since the Pentium Pro fall under "Family 6".
The ACPI _PSS object returns a table of supported P-states (frequency/voltage pairs). For Intel CPUs, the OS may supplement or override these with its own driver (e.g., intel_pstate ), but the ACPI values serve as a fallback.
