Unfortunately, the default NUMA node ID breaks socket boundary and leads to the broken CPU topology warning message in Linux guest. This series intends to fix the issue. PATCH[1/4] Uses SMP configuration to populate CPU topology PATCH[2/4] Fixes the broken CPU topology by considering the socket boundary when the default NUMA node ID is given PATCH[3/4] Uses the populated CPU topology to build PPTT table, instead of calculate it again PATCH[4/4] Take thread ID as the ACPI processor ID in MDAT and SRAT tables Changelog ========= v3: * Split PATCH[v2 1/3] to PATCH[v3 1/4] and PATCH[v3 2/4] (Yanan) * Don't take account of die ID in CPU topology population and added assert(!mc->smp_props.dies_supported) (Yanan/Igor) * Assign cluster_id and use it when building PPTT table (Yanan/Igor) v2: * Populate the CPU topology in virt_possible_cpu_arch_ids() so that it can be reused in virt_get_default_cpu_node_id() (Igor) * Added PATCH[2/3] to use the existing CPU topology when the PPTT table is built (Igor) * Added PATCH[3/3] to take thread ID as ACPI processor ID in MADT and SRAT table (Gavin) Gavin Shan (4): hw/arm/virt: Consider SMP configuration in CPU topology hw/arm/virt: Fix CPU's default NUMA node ID hw/acpi/aml-build: Use existing CPU topology to build PPTT table hw/arm/virt: Unify ACPI processor ID in MADT and SRAT table hw/acpi/aml-build.c | 96 ++++++++++++++++++++++++++++++---------- hw/arm/virt-acpi-build.c | 12 +++-- hw/arm/virt.c | 15 ++++++- qapi/machine.json | 6 ++- 4 files changed, 99 insertions(+), 30 deletions(-)
