In this case, it's impossible to provide the default CPU-to-NUMA mapping or association based on the socket ID of the given CPU. This takes account of SMP configuration when the CPU topology is populated. The die ID for the given CPU isn't assigned since it's not supported on arm/virt machine. Besides, the used SMP configuration in qtest/numa-test/aarch64_numa_cpu() is corrcted to avoid testing failure Signed-off-by: Gavin Shan Reviewed-by: Yanan Wang --- hw/arm/virt.c | 15 ++++++++++++++- tests/qtest/numa-test.c | 3 ++- 2 files changed, 16 insertions(+), 2 deletions(-) diff --git a/hw/arm/virt.c b/hw/arm/virt.c index d2e5ecd234..5443ecae92 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -2505,6 +2505,7 @@ static const CPUArchIdList *virt_possible_cpu_arch_ids(MachineState *ms) int n; unsigned int max_cpus = ms->smp.max_cpus; VirtMachineState *vms = VIRT_MACHINE(ms); + MachineClass *mc = MACHINE_GET_CLASS(vms); if (ms->possible_cpus) { assert(ms->possible_cpus->len == max_cpus); @@ -2518,8 +2519,20 @@ static const CPUArchIdList *virt_possible_cpu_arch_ids(MachineState *ms) ms->possible_cpus->cpus[n].type = ms->cpu_type; ms->possible_cpus->cpus[n].arch_id = virt_cpu_mp_affinity(vms, n); + + assert(!mc->smp_props.dies_supported); + ms->possible_cpus->cpus[n].props.has_socket_id = true; + ms->possible_cpus->cpus[n].props.socket_id = + (n / (ms->smp.clusters * ms->smp.cores * ms->smp.threads)); + ms->possible_cpus->cpus[n].props.has_cluster_id = true; + ms->possible_cpus->cpus[n].props.cluster_id = + (n / (ms->smp.cores * ms->smp.threads)) % ms->smp.clusters; + ms->possible_cpus->cpus[n].props.has_core_id = true; + ms->possible_cpus->cpus[n].props.core_id = + (n / ms->smp.threads) % ms->smp.cores; ms->possible_cpus->cpus[n].props.has_thread_id = true; - ms->possible_cpus->cpus[n].props.thread_id = n; + ms->possible_cpus->cpus[n].props.thread_id = + n % ms->smp.threads; } return ms->possible_cpus; } diff --git a/tests/qtest/numa-test.c b/tests/qtest/numa-test.c index 90bf68a5b3..aeda8c774c 100644 --- a/tests/qtest/numa-test.c +++ b/tests/qtest/numa-test.c @@ -223,7 +223,8 @@ static void aarch64_numa_cpu(const void *data) QTestState *qts; g_autofree char *cli = NULL; - cli = make_cli(data, "-machine smp.cpus=2 " + cli = make_cli(data, "-machine " + "smp.cpus=2,smp.sockets=1,smp.clusters=1,smp.cores=1,smp.threads=2 " "-numa node,nodeid=0,memdev=ram -numa node,nodeid=1 " "-numa cpu,node-id=1,thread-id=0 " "-numa cpu,node-id=0,thread-id=1");
