From c61eabb8aa86fed57c2cd5394e0e89e350c99c5e Mon Sep 17 00:00:00 2001 From: Tao Su <tao1.su@linux.intel.com> Date: Wed, 20 Mar 2024 10:10:44 +0800 Subject: [PATCH] target/i386: Add new CPU model SierraForest MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 6e82d3b6220777667968a04c87e1667f164ebe88 upstream. According to table 1-2 in Intel Architecture Instruction Set Extensions and Future Features (rev 051) [1], SierraForest has the following new features which have already been virtualized: - CMPCCXADD CPUID.(EAX=7,ECX=1):EAX[bit 7] - AVX-IFMA CPUID.(EAX=7,ECX=1):EAX[bit 23] - AVX-VNNI-INT8 CPUID.(EAX=7,ECX=1):EDX[bit 4] - AVX-NE-CONVERT CPUID.(EAX=7,ECX=1):EDX[bit 5] Add above features to new CPU model SierraForest. Comparing with GraniteRapids CPU model, SierraForest bare-metal removes the following features: - HLE CPUID.(EAX=7,ECX=0):EBX[bit 4] - RTM CPUID.(EAX=7,ECX=0):EBX[bit 11] - AVX512F CPUID.(EAX=7,ECX=0):EBX[bit 16] - AVX512DQ CPUID.(EAX=7,ECX=0):EBX[bit 17] - AVX512_IFMA CPUID.(EAX=7,ECX=0):EBX[bit 21] - AVX512CD CPUID.(EAX=7,ECX=0):EBX[bit 28] - AVX512BW CPUID.(EAX=7,ECX=0):EBX[bit 30] - AVX512VL CPUID.(EAX=7,ECX=0):EBX[bit 31] - AVX512_VBMI CPUID.(EAX=7,ECX=0):ECX[bit 1] - AVX512_VBMI2 CPUID.(EAX=7,ECX=0):ECX[bit 6] - AVX512_VNNI CPUID.(EAX=7,ECX=0):ECX[bit 11] - AVX512_BITALG CPUID.(EAX=7,ECX=0):ECX[bit 12] - AVX512_VPOPCNTDQ CPUID.(EAX=7,ECX=0):ECX[bit 14] - LA57 CPUID.(EAX=7,ECX=0):ECX[bit 16] - TSXLDTRK CPUID.(EAX=7,ECX=0):EDX[bit 16] - AMX-BF16 CPUID.(EAX=7,ECX=0):EDX[bit 22] - AVX512_FP16 CPUID.(EAX=7,ECX=0):EDX[bit 23] - AMX-TILE CPUID.(EAX=7,ECX=0):EDX[bit 24] - AMX-INT8 CPUID.(EAX=7,ECX=0):EDX[bit 25] - AVX512_BF16 CPUID.(EAX=7,ECX=1):EAX[bit 5] - fast zero-length MOVSB CPUID.(EAX=7,ECX=1):EAX[bit 10] - fast short CMPSB, SCASB CPUID.(EAX=7,ECX=1):EAX[bit 12] - AMX-FP16 CPUID.(EAX=7,ECX=1):EAX[bit 21] - PREFETCHI CPUID.(EAX=7,ECX=1):EDX[bit 14] - XFD CPUID.(EAX=0xD,ECX=1):EAX[bit 4] - EPT_PAGE_WALK_LENGTH_5 VMX_EPT_VPID_CAP(0x48c)[bit 7] Add all features of GraniteRapids CPU model except above features to SierraForest CPU model. SierraForest doesn’t support TSX and RTM but supports TAA_NO. When RTM is not enabled in host, KVM will not report TAA_NO. So, just don't include TAA_NO in SierraForest CPU model.
