Acpi Genuineintel---intel64-family-6-model-58 Online

ACPI: Processor [CPU0] (supports 8 throttling states, 8 performance states, 2 C-states) acpi genuineintel---intel64-family-6-model-58 This is a (not error or warning). It tells the developer that the ACPI subsystem has successfully mapped the generic "Processor" object to a real Intel CPU with known behavior. Part 4: Common Scenarios Where You See This Keyword 1. Kernel Boot Logs (dmesg) Run dmesg | grep -i "acpi genuineintel" and you might see it during CPU enumeration. It is normal and harmless. 2. Building Custom Kernels If you compile your own kernel and enable CONFIG_ACPI_PROCESSOR and CONFIG_X86_CPU_DEBUG , these verbose strings will appear. Some distribution kernels (like Arch or Gentoo) leave these debug prints enabled by default. 3. Virtualization (KVM/QEMU) When a VM is configured with -cpu host or -cpu IvyBridge , the hypervisor passes the CPUID information to the guest. The guest kernel will see "GenuineIntel, Family 6, Model 58" if the host or emulated CPU is Ivy Bridge. ACPI in the guest then prints the same string. 4. Error or Mismatch Warnings Sometimes users see this string adjacent to an error like:

acpi genuineintel---intel64-family-6-model-151 Thus, the pattern is permanent. If you are writing scripts or log parsers that match this string, like: acpi genuineintel---intel64-family-6-model-58

For the average user, ignore it. For the system tuner or kernel developer, it is a valuable breadcrumb. It reminds us that under every sleek user interface, a silent conversation happens between firmware and kernel – one that speaks in families, models, and ACPI states. ACPI: Processor [CPU0] (supports 8 throttling states, 8

Newer CPUs (Skylake, Family 6 Model 94; Cascade Lake, Model 85; Alder Lake, Model 151) produce similar strings, e.g.: Kernel Boot Logs (dmesg) Run dmesg | grep
