Product : Fedora 31
Version : 2.1
Release : 39.fc31
URL : https://pagure.io/microcode_ctl
Summary : Tool to transform and deploy CPU microcode update for x86
Description :
The microcode_ctl utility is a companion to the microcode driver written
by Tigran Aivazian <tigran@aivazian.fsnet.co.uk>.

The microcode update is volatile and needs to be uploaded on each system
boot i.e. it doesn't reflash your cpu permanently, reboot and it reverts
back to the old microcode.
