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[1/3]: Fixes the broken CPU topology by considering the socket boundary when the default NUMA node ID is calculated. PATCH[2/3]: Use the existing CPU topology to build PPTT table. However, the cluster ID has to be calculated dynamically because there is no corresponding information in CPU instance properties. PATCH[3/3]: Take thread ID as the ACPI processor ID in MDAT and SRAT tables. Changelog ========= 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 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 (3): 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 | 106 ++++++++++++++++++++++++++++++--------- hw/arm/virt-acpi-build.c | 12 +++-- hw/arm/virt.c | 17 ++++++- 3 files changed, 107 insertions(+), 28 deletions(-)
