[v3,0/4] hw/arm/virt: Fix CPU's default NUMA node ID

Message

Gavin Shan March 23, 2022, 7:24 a.m. UTC

When the CPU-to-NUMA association isn't provided by user, the default NUMA
node ID for the specific CPU is returned from virt_get_default_cpu_node_id().
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)
