Thus, define CPU topology enumeration in qapi/machine.json to make it generic for all architectures. To match the general topology naming style, rename CPU_TOPO_LEVEL_* to CPU_TOPOLOGY_LEVEL_*, and rename SMT and package levels to thread and socket. Also, enumerate additional topology levels for non-i386 arches, and add a CPU_TOPOLOGY_LEVEL_DEFAULT to help future smp-cache object to work with compatibility requirement of arch-specific cache topology models. Signed-off-by: Zhao Liu Tested-by: Yongwei Ma --- Changes since Patch v1: * Dropped prefix of CpuTopologyLevel enumeration. (Markus) * Rename CPU_TOPO_LEVEL_* to CPU_TOPOLOGY_LEVEL_* to match the QAPI's generated code. (Markus) Changes since RFC v2: * Dropped cpu-topology.h and cpu-topology.c since QAPI has the helper (CpuTopologyLevel_str) to convert enum to string. (Markus) * Fixed text format in machine.json (CpuTopologyLevel naming, 2 spaces between sentences). (Markus) * Added a new level "default" to de-compatibilize some arch-specific topo settings. (Daniel) * Moved CpuTopologyLevel to qapi/machine-common.json, at where the cache enumeration and smp-cache object would be added. - If smp-cache object is defined in qapi/machine.json, storage-daemon will complain about the qmp cmds in qapi/machine.json during compiling. Changes since RFC v1: * Used QAPI to enumerate CPU topology levels. * Dropped string_to_cpu_topo() since QAPI will help to parse the topo levels. --- hw/i386/x86-common.c | 4 +- include/hw/i386/topology.h | 22 +----- qapi/machine-common.json | 46 +++++++++++- target/i386/cpu.c | 144 ++++++++++++++++++------------------- target/i386/cpu.h | 4 +- 5 files changed, 124 insertions(+), 96 deletions(-) diff --git a/hw/i386/x86-common.c b/hw/i386/x86-common.c index 992ea1f25e94..b21d2ab97349 100644 --- a/hw/i386/x86-common.c +++ b/hw/i386/x86-common.c @@ -273,12 +273,12 @@ void x86_cpu_pre_plug(HotplugHandler *hotplug_dev, if (ms->smp.modules > 1) { env->nr_modules = ms->smp.modules; - set_bit(CPU_TOPO_LEVEL_MODULE, env->avail_cpu_topo); + set_bit(CPU_TOPOLOGY_LEVEL_MODULE, env->avail_cpu_topo); } if (ms->smp.dies > 1) { env->nr_dies = ms->smp.dies; - set_bit(CPU_TOPO_LEVEL_DIE, env->avail_cpu_topo); + set_bit(CPU_TOPOLOGY_LEVEL_DIE, env->avail_cpu_topo); } /* diff --git a/include/hw/i386/topology.h b/include/hw/i386/topology.h index dff49fce1154..bf740383038b 100644 --- a/include/hw/i386/topology.h +++ b/include/hw/i386/topology.h @@ -39,7 +39,7 @@ * CPUID Fn8000_0008_ECX[ApicIdCoreIdSize[3:0]] is set to apicid_core_width(). */ - +#include "qapi/qapi-types-machine-common.h" #include "qemu/bitops.h" /* @@ -62,22 +62,6 @@ typedef struct X86CPUTopoInfo { unsigned threads_per_core; } X86CPUTopoInfo; -/* - * CPUTopoLevel is the general i386 topology hierarchical representation, - * ordered by increasing hierarchical relationship. - * Its enumeration value is not bound to the type value of Intel (CPUID[0x1F]) - * or AMD (CPUID[0x80000026]). - */ -enum CPUTopoLevel { - CPU_TOPO_LEVEL_INVALID, - CPU_TOPO_LEVEL_SMT, - CPU_TOPO_LEVEL_CORE, - CPU_TOPO_LEVEL_MODULE, - CPU_TOPO_LEVEL_DIE, - CPU_TOPO_LEVEL_PACKAGE, - CPU_TOPO_LEVEL_MAX, -}; - /* Return the bit width needed for 'count' IDs */ static unsigned apicid_bitwidth_for_count(unsigned count) { @@ -212,8 +196,8 @@ static inline apic_id_t x86_apicid_from_cpu_idx(X86CPUTopoInfo *topo_info, */ static inline bool x86_has_extended_topo(unsigned long *topo_bitmap) { - return test_bit(CPU_TOPO_LEVEL_MODULE, topo_bitmap) || - test_bit(CPU_TOPO_LEVEL_DIE, topo_bitmap); + return test_bit(CPU_TOPOLOGY_LEVEL_MODULE, topo_bitmap) || + test_bit(CPU_TOPOLOGY_LEVEL_DIE, topo_bitmap); } #endif /* HW_I386_TOPOLOGY_H */ diff --git a/qapi/machine-common.json b/qapi/machine-common.json index fa6bd71d1280..148a2c8dccca 100644 --- a/qapi/machine-common.json +++ b/qapi/machine-common.json @@ -5,7 +5,7 @@ # See the COPYING file in the top-level directory. ## -# = Machines S390 data types +# = Common machine types ## ## @@ -19,3 +19,47 @@ { 'enum': 'CpuS390Entitlement', 'prefix': 'S390_CPU_ENTITLEMENT', 'data': [ 'auto', 'low', 'medium', 'high' ] } + +## +# @CpuTopologyLevel: +# +# An enumeration of CPU topology levels. +# +# @invalid: Invalid topology level. +# +# @thread: thread level, which would also be called SMT level or +# logical processor level.
