Subject: [PATCH v2 0/3] hw/arm/virt: Fix CPU's default NUMA node ID
Date: Thu, 3 Mar 2022 11:11:49 +0800 [thread overview]
Message-ID: <20220303031152.145960-1-gshan@redhat.com> (raw)
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[1/3]: 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)
