title: Plugin: 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.
