Subject: [PATCH 5/7] target/i386: Add few security fix bits in ARCH_CAPABILITIES into SapphireRapids CPU model
Date: Fri, 16 Jun 2023 11:23:09 +0800 [thread overview]
Message-ID: <20230616032311.19137-6-tao1.su@linux.intel.com> (raw)
In-Reply-To: <20230616032311.19137-1-tao1.su@linux.intel.com>
From: Lei Wang <lei4.wang@intel.com>
Latest stepping (8) of SapphireRapids has bit 13, 14 and 15 of
MSR_IA32_ARCH_CAPABILITIES enabled, which are related to some security
fixes.
Add version 2 of SapphireRapids CPU model with those bits enabled also.
