The new field can be used to find out reasons that prevent the CPU model from running in the current host. This will return information based on the current machine and accelerator only. In the future we may extend these mechanisms to allow querying other machines and other accelerators without restarting QEMU, but it will require some reorganization of QEMU's main code. This series is based on my 'x86-next' branch, at: git://github.com/ehabkost/qemu.git x86-next Changes v1 -> v2: * Fixed documentation to say "(since 2.7)" * Removed @runnable field, improved documentation Example command output: { "return": [ { "unavailable-features": [ "kvm" ], "name": "host" }, { "unavailable-features": [], "name": "qemu64" }, { "unavailable-features": [], "name": "qemu32" }, { "unavailable-features": ["npt", "fxsr-opt", "vme"], "name": "phenom" }, { "unavailable-features": ["vme"], "name": "pentium3" }, { "unavailable-features": ["vme"], "name": "pentium2" }, { "unavailable-features": ["vme"], "name": "pentium" }, { "unavailable-features": ["vme"], "name": "n270" }, { "unavailable-features": ["vme"], "name": "kvm64" }, { "unavailable-features": ["vme"], "name": "kvm32" }, { "unavailable-features": ["vme"], "name": "coreduo" }, { "unavailable-features": ["vme"], "name": "core2duo" }, { "unavailable-features": ["vme"], "name": "athlon" }, { "unavailable-features": ["vme"], "name": "Westmere" }, { "unavailable-features": ["xsavec", "3dnowprefetch", "rdseed", "rt= m", "invpcid", "erms", "avx2", "hle", "rdrand", "f16c", "avx", "tsc-deadl= ine", "x2apic", "pcid", "fma", "vme"], "name": "Skylake-Client" }, { "unavailable-features": ["avx", "tsc-deadline", "x2apic", "vme"], "name": "SandyBridge" }, { "unavailable-features": ["vme"], "name": "Penryn" }, { "unavailable-features": ["tbm", "fma4", "xop", "3dnowprefetch", "= misalignsse", "f16c", "avx", "fma", "vme"], "name": "Opteron_G5" }, { "unavailable-features": ["fma4", "xop", "3dnowprefetch", "misalig= nsse", "avx", "vme"], "name": "Opteron_G4" }, { "unavailable-features": ["misalignsse", "vme"], "name": "Opteron_G3" }, { "unavailable-features": ["vme"], "name": "Opteron_G2" }, { "unavailable-features": ["vme"], "name": "Opteron_G1" }, { "unavailable-features": ["vme"], "name": "Nehalem" }, { "unavailable-features": ["erms", "rdrand", "f16c", "avx", "tsc-de= adline", "x2apic", "vme"], "name": "IvyBridge" }, { "unavailable-features": ["rtm", "invpcid", "erms", "avx2", "hle",= "rdrand", "f16c", "avx", "tsc-deadline", "x2apic", "pcid", "fma", "vme"]= , "name": "Haswell" }, { "unavailable-features": ["invpcid", "erms", "avx2", "rdrand", "f1= 6c", "avx", "tsc-deadline", "x2apic", "pcid", "fma", "vme"], "name": "Haswell-noTSX" }, { "unavailable-features": ["vme"], "name": "Conroe" }, { "unavailable-features": ["3dnowprefetch", "rdseed", "rtm", "invpc= id", "erms", "avx2", "hle", "rdrand", "f16c", "avx", "tsc-deadline", "x2a= pic", "pcid", "fma", "vme"], "name": "Broadwell" }, { "unavailable-features": ["3dnowprefetch", "rdseed", "invpcid", "e= rms", "avx2", "rdrand", "f16c", "avx", "tsc-deadline", "x2apic", "pcid", = "fma", "vme"], "name": "Broadwell-noTSX" }, { "unavailable-features": ["vme"], "name": "486" } ]} Cc: David Hildenbrand Cc: Michael Mueller Cc: Christian Borntraeger Cc: Cornelia Huck Cc: Jiri Denemark Cc: libvir-list@redhat.com Eduardo Habkost (6): target-i386: List CPU models using subclass list target-i386: Move warning code outside x86_cpu_filter_features() target-i386: Define CPUID filtering functions before x86_cpu_list() qmp: Add runnability information to query-cpu-definitions target-i386: Use "-" instead of "_" on all feature names target-i386: Return runnability information on query-cpu-definitions qapi-schema.json | 23 ++++- target-i386/cpu-qom.h | 4 + target-i386/cpu.c | 262 +++++++++++++++++++++++++++++++++++---------= ------ 3 files changed, 209 insertions(+), 80 deletions(-) --=20 2.5.5
