X-Received-From: 192.55.52.43 Subject: [Qemu-devel] [PATCH v2 5/5] i386: Add new CPU model Icelake-{Server, Client} X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: robert.hu@intel.com, Robert Hoo Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" New CPU models mostly inherit features from ancestor Skylake, while addin new features: UMIP, New Instructions ( PCONIFIG (server only), WBNOINVD, AVX512_VBMI2, GFNI, AVX512_VNNI, VPCLMULQDQ, VAES, AVX512_BITALG), Intel PT and 5-level paging (Server only). As well as IA32_PRED_CMD and IA32_ARCH_CAPABILITIES MSRs, SSBD support for speculative execution side channel mitigations. Note: For 5-level paging, Guest physical address width can be configured, with parameter "phys-bits". Unless explicitly specified, we still use its default value, even for Icelake-Server cpu model.
