Subject: [PATCH 0/2] x86/microcode/intel: Extend BDW late-loading with platform id and LLC check
Date: Mon, 15 Jan 2018 13:43:21 +0800 [thread overview]
Message-ID: <1515995003-113069-1-git-send-email-zhang.jia@linux.alibaba.com> (raw)
The fix further reduces the impact for the BDW model which has to launch
a machine reset in order to run microcode update in BIOS. This point is
important for some vendors without the concern about machine reboot in
order to fix up Spectre v2.
