microcode_ctl - CPU microcode updates for Intel x86 processors
- Description:
This package provides microcode update files for Intel x86 and x86_64 CPUs.
The microcode update is volatile and needs to be uploaded on each system
boot i.e. it isn't stored on a CPU permanently; reboot and it reverts
back to the old microcode.
Package name "microcode_ctl" is historical, as the binary with the same name
is no longer used for microcode upload and, as a result, no longer provided.
