Tsirkin" , Boqun Feng From: Boqun Feng A new cpu model called "KnightsMill" is added to model Knights Mill processors. Compared to "Skylake-Server" cpu model, the following features are added: avx512_4vnniw avx512_4fmaps avx512pf avx512er avx512_vpopcntdq and the following features are removed: pcid invpcid clflushopt avx512dq avx512bw clwb smap rtm mpx xsavec xgetbv1 hle Signed-off-by: Boqun Feng Message-Id: <20180320000821.8337-1-boqun.feng@intel.com> Signed-off-by: Eduardo Habkost --- target/i386/cpu.c | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) diff --git a/target/i386/cpu.c b/target/i386/cpu.c index b0a1c629a3..52fd35b6a1 100644 --- a/target/i386/cpu.c +++ b/target/i386/cpu.c @@ -1839,6 +1839,48 @@ static X86CPUDefinition builtin_x86_defs[] = { .xlevel = 0x80000008, .model_id = "Intel Xeon Processor (Skylake, IBRS)", }, + { + .name = "KnightsMill", + .level = 0xd, + .vendor = CPUID_VENDOR_INTEL, + .family = 6, + .model = 133, + .stepping = 0, + .features[FEAT_1_EDX] = + CPUID_VME | CPUID_SS | CPUID_SSE2 | CPUID_SSE | CPUID_FXSR | + CPUID_MMX | CPUID_CLFLUSH | CPUID_PSE36 | CPUID_PAT | CPUID_CMOV | + CPUID_MCA | CPUID_PGE | CPUID_MTRR | CPUID_SEP | CPUID_APIC | + CPUID_CX8 | CPUID_MCE | CPUID_PAE | CPUID_MSR | CPUID_TSC | + CPUID_PSE | CPUID_DE | CPUID_FP87, + .features[FEAT_1_ECX] = + CPUID_EXT_AVX | CPUID_EXT_XSAVE | CPUID_EXT_AES | + CPUID_EXT_POPCNT | CPUID_EXT_X2APIC | CPUID_EXT_SSE42 | + CPUID_EXT_SSE41 | CPUID_EXT_CX16 | CPUID_EXT_SSSE3 | + CPUID_EXT_PCLMULQDQ | CPUID_EXT_SSE3 | + CPUID_EXT_TSC_DEADLINE_TIMER | CPUID_EXT_FMA | CPUID_EXT_MOVBE | + CPUID_EXT_F16C | CPUID_EXT_RDRAND, + .features[FEAT_8000_0001_EDX] = + CPUID_EXT2_LM | CPUID_EXT2_PDPE1GB | CPUID_EXT2_RDTSCP | + CPUID_EXT2_NX | CPUID_EXT2_SYSCALL, + .features[FEAT_8000_0001_ECX] = + CPUID_EXT3_ABM | CPUID_EXT3_LAHF_LM | CPUID_EXT3_3DNOWPREFETCH, + .features[FEAT_7_0_EBX] = + CPUID_7_0_EBX_FSGSBASE | CPUID_7_0_EBX_BMI1 | CPUID_7_0_EBX_AVX2 | + CPUID_7_0_EBX_SMEP | CPUID_7_0_EBX_BMI2 | CPUID_7_0_EBX_ERMS | + CPUID_7_0_EBX_RDSEED | CPUID_7_0_EBX_ADX | CPUID_7_0_EBX_AVX512F | + CPUID_7_0_EBX_AVX512CD | CPUID_7_0_EBX_AVX512PF | + CPUID_7_0_EBX_AVX512ER, + .features[FEAT_7_0_ECX] = + CPUID_7_0_ECX_AVX512_VPOPCNTDQ, + .features[FEAT_7_0_EDX] = + CPUID_7_0_EDX_AVX512_4VNNIW | CPUID_7_0_EDX_AVX512_4FMAPS, + .features[FEAT_XSAVE] = + CPUID_XSAVE_XSAVEOPT, + .features[FEAT_6_EAX] = + CPUID_6_EAX_ARAT, + .xlevel = 0x80000008, + .model_id = "Intel Xeon Phi Processor (Knights Mill)", + }, { .name = "Opteron_G1", .level = 5, -- 2.14.3
