# CPU Microcode

## 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.
