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] Add cluster-id to CPU instance property
PATCH[2/4] Uses SMP configuration to populate CPU topology
PATCH[3/4] Fixes the broken CPU topology by considering the socket boundary
when the default NUMA node ID is given
PATCH[4/4] Uses the populated CPU topology to build PPTT table, instead of
calculate it again
Changelog
=========
v4/v5:
* Split PATCH[v3 1/3] to PATCH[v5 1/4] and PATCH[v5 2/4].
Verify or dump 'clsuter-id' in various spots (Yanan)
* s/within cluster/within cluster\/die/ for 'core-id' in
qapi/machine.json (Igor)
* Apply '% ms->smp.{sockets, clusters, cores, threads} in
virt_possible_cpu_arch_ids() as x86 does (Igor)
* Use [0 - possible_cpus->len] as ACPI processor UID to
build PPTT table and PATCH[v3 4/4] is dropped (Igor)
* Simplified build_pptt() to add all entries in one loop
on ms->possible_cpus (Igor)
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)
