Introduction

This plugin reads the sysfs attributes associated with CPU microcode. It displays a read-only value of the CPU microcode version loaded onto the physical CPU at fwupd startup.

GUID Generation

These devices add extra instance IDs from the CPUID values, e.g.

  • CPUID\PRO_0&FAM_06
  • CPUID\PRO_0&FAM_06&MOD_0E
  • CPUID\PRO_0&FAM_06&MOD_0E&STP_3

External Interface Access

This plugin requires no extra access.
