[RFC][PATCH 0/4] x86/cpu: Remove duplicate microcode version matching infrastructure
From: Dave Hansen
Date: Wed Nov 20 2024 - 15:24:18 EST
x86 has generic CPU matching infrastructure. This lets you build
tables of CPUs with some property. It's mostly used for enumerating
model-specific features, but it is quite a bit more flexible than
that. In includes a facility to match steppings and microcode
versions. This generic infrastructure is built around 'struct
x86_cpu_id'.
There is a less generic, parallel CPU matching facility built around
'struct x86_cpu_desc'. It is used only for matching specific microcode
revisions. All of the 'struct x86_cpu_desc' users can be converted to
'struct x86_cpu_id'.
Do that conversion then remove the 'struct x86_cpu_desc'
infrastructure.
Testing or acks would be much appreciated!
