[PATCH 0/3] x86/ucode: Simplify/fix loading paths further

Posted by Andrew Cooper 12 months ago

collect_cpu_info() is fairly expensive and called excessively.  Rationalise
this substantially.

Except I found yet another bug when testing this.  Notes in patch 3.

Andrew Cooper (3):
  x86/ucode: Don't use microcode_update_cpu() in early_microcode_load()
  x86/ucode: Fold microcode_update_cpu() and fix error handling
  x86/ucode: Remove the collect_cpu_info() call from parse_blob()
