Subject: [PATCH v2 1/2] target/i386: Remove split lock detect in Snowridge CPU model
Date: Fri, 27 Aug 2021 14:48:17 +0800 [thread overview]
Message-ID: <20210827064818.4698-2-chenyi.qiang@intel.com> (raw)
In-Reply-To: <20210827064818.4698-1-chenyi.qiang@intel.com>
At present, there's no mechanism intelligent enough to virtualize split
lock detection correctly. Remove it in Snowridge CPU model to avoid the
feature exposure.
