[PATCH v9 0/6] hw/arm/virt: Fix CPU's default NUMA node ID |
Date: |

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 by populating full CPU toplogy on arm/virt machine.
PATCH[1/6] Add cluster-id to CPU instance property
PATCH[2/6] Fixes test failure in qtest/numa-test/aarch64_numa_cpu()
PATCH[3/6] Uses SMP configuration to populate CPU topology
PATCH[4/6] Corrects CPU/NUMA association in qtest/numa-test/aarch64_numa_cpu()
PATCH[5/6] Fixes the broken CPU topology by considering the socket boundary
when the default NUMA node ID is given
PATCH[6/6] Uses the populated CPU topology to build PPTT table, instead of
calculate it again
Changelog
=========
v9:
* Fix typo by replacing 'thrad-id' with 'thread-id' in
PATCH[v9 2/6]'s commit log (Igor)
* Added PATCH[v9 4/6] to make CPU-to-NUMA association
real (Igor)
v8:
* Separate PATCH[v8 2/5] to fix test failure in qtest/
numa-test/aarch64_numa_cpu() (Igor)
* Improvents to coding style, changelog and comments (Yanan)
v6/v7:
* Fixed description for 'cluster-id' and 'core-id' (Yanan)
* Remove '% ms->smp.sockets' in socket ID calculation (Yanan)
* Fixed tests/qtest/numa-test/aarch64_numa_cpu() (Yanan)
* Initialized offset variables in build_pptt() (Jonathan)
* Added comments about the expected and sorted layout of
cpus[n].props.*_id and assert() on the exceptional cases (Igor)
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)
