Subject: [PATCH v3 0/5] x86/xen-ucode: Introduce --force option
Date: Tue, 30 Apr 2024 13:47:04 +0100 [thread overview]
Message-ID: <20240430124709.865183-1-fouad.hilly@cloud.com> (raw)
Refactor and introduce --force option to xen-ucode, which skips microcode
version check when updating x86 CPU micocode. A new hypercall introduced
with flags field to facilitate the new option and allow for future flags
as needed.
This change is required to enable developers to load ucode that is the same version as the
one already loaded for testing. On top of that Intel is introducing "min rev", which will
require a mechanism to override version checks
Fouad Hilly (5):
x86: Update x86 low level version check of microcode
x86: Refactor microcode_update() hypercall with flags
x86: Add usage() to print out usage message
x86: Use getopt to handle command line args
Add --force option to xen-ucode to override microcode version check
