[libvirt] [PATCH 2/2] cpu: Add new EPYC CPU model

From: Brijesh Singh <brijesh.singh(a)amd.com&gt; Add a new CPU model called 'EPYC' to model processors from AMD EPYC family (which includes EPYC 76xx,75xx,74xx, 73xx and 72xx). The following features bits have been added/removed compare to Opteron_G5 Added: monitor, movbe, rdrand, mmxext, ffxsr, rdtscp, cr8legacy, osvw, fsgsbase, bmi1, avx2, smep, bmi2, rdseed, adx, smap, clfshopt, sha xsaveopt, xsavec, xgetbv1, arat Removed: xop, fma4, tbm The patch is depend on EPYC CPU model supported introduced in qemu [1] [1] https://patchwork.kernel.org/patch/9902205/ Cc: Tom Lendacky <Thomas.Lendacky(a)amd.com&gt; Signed-off-by: Brijesh Singh <brijesh.singh(a)amd.com&gt; Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/cpu/cpu_map.xml | 74 ++++++++++++++++++++++ ...x86_64-cpuid-Ryzen-7-1800X-Eight-Core-guest.xml | 26 +------- .../x86_64-cpuid-Ryzen-7-1800X-Eight-Core-host.xml | 33 +--------- .../x86_64-cpuid-Ryzen-7-1800X-Eight-Core-json.xml | 27 +------- 4 files changed, 79 insertions(+), 81 deletions(-) diff --git a/src/cpu/cpu_map.xml b/src/cpu/cpu_map.xml index 8e7ac4973d..6243fbe902 100644 --- a/src/cpu/cpu_map.xml +++ b/src/cpu/cpu_map.xml @@ -260,6 +260,9 @@ <feature name='avx512cd'> <cpuid eax_in='0x07' ecx_in='0x00' ebx='0x10000000'/> </feature> + <feature name='sha-ni'> + <cpuid eax_in='0x07' ecx_in='0x00' ebx='0x20000000'/> + </feature> <feature name='avx512bw'> <cpuid eax_in='0x07' ecx_in='0x00' ebx='0x40000000'/> </feature> @@ -1545,6 +1548,77 @@ <feature name='xop'/> <feature name='xsave'/> </model> + + <model name='EPYC'> + <signature family='23' model='1'/> + <vendor name='AMD'/> + <feature name='3dnowprefetch'/> + <feature name='abm'/> + <feature name='adx'/> + <feature name='aes'/> + <feature name='apic'/> + <feature name='arat'/> + <feature name='avx'/> + <feature name='avx2'/> + <feature name='bmi1'/> + <feature name='bmi2'/> + <feature name='clflush'/> + <feature name='clflushopt'/> + <feature name='cmov'/> + <feature name='cr8legacy'/> + <feature name='cx16'/> + <feature name='cx8'/> + <feature name='de'/> + <feature name='f16c'/> + <feature name='fma'/> + <feature name='fpu'/> + <feature name='fsgsbase'/> + <feature name='fxsr'/> + <feature name='fxsr_opt'/> + <feature name='lahf_lm'/> + <feature name='lm'/> + <feature name='mca'/> + <feature name='mce'/> + <feature name='misalignsse'/> + <feature name='mmx'/> + <feature name='mmxext'/> + <feature name='monitor'/> + <feature name='movbe'/> + <feature name='msr'/> + <feature name='mtrr'/> + <feature name='nx'/> + <feature name='osvw'/> + <feature name='pae'/> + <feature name='pat'/> + <feature name='pclmuldq'/> + <feature name='pdpe1gb'/> + <feature name='pge'/> + <feature name='pni'/> + <feature name='popcnt'/> + <feature name='pse'/> + <feature name='pse36'/> + <feature name='rdrand'/> + <feature name='rdseed'/> + <feature name='rdtscp'/> + <feature name='sep'/> + <feature name='sha-ni'/> + <feature name='smap'/> + <feature name='smep'/> + <feature name='sse'/> + <feature name='sse2'/> + <feature name='sse4.1'/> + <feature name='sse4.2'/> + <feature name='sse4a'/> + <feature name='ssse3'/> + <feature name='svm'/> + <feature name='syscall'/> + <feature name='tsc'/> + <feature name='vme'/> + <feature name='xgetbv1'/> + <feature name='xsave'/> + <feature name='xsavec'/> + <feature name='xsaveopt'/> + </model> </arch> <arch name='ppc64'> diff --git a/tests/cputestdata/x86_64-cpuid-Ryzen-7-1800X-Eight-Core-guest.xml b/tests/cputestdata/x86_64-cpuid-Ryzen-7-1800X-Eight-Core-guest.xml index fcad36e34e..18edb71bcd 100644 --- a/tests/cputestdata/x86_64-cpuid-Ryzen-7-1800X-Eight-Core-guest.xml +++ b/tests/cputestdata/x86_64-cpuid-Ryzen-7-1800X-Eight-Core-guest.xml @@ -1,32 +1,11 @@ <cpu mode='custom' match='exact'> -
