From e97c563f7146098119839aa146a6f25070eb7148 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Wed, 11 May 2022 18:01:02 +0800 Subject: [PATCH 01/16] qapi/machine.json: Add cluster-id RH-Author: Gavin Shan RH-MergeRequest: 86: hw/arm/virt: Fix the default CPU topology RH-Commit: [1/6] 44d7d83008c6d28485ae44f7cced792f4987b919 (gwshan/qemu-rhel-9) RH-Bugzilla: 2041823 RH-Acked-by: Eric Auger RH-Acked-by: Cornelia Huck RH-Acked-by: Andrew Jones Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2041823 This adds cluster-id in CPU instance properties, which will be used by arm/virt machine. Besides, the cluster-id is also verified or dumped in various spots: * hw/core/machine.c::machine_set_cpu_numa_node() to associate CPU with its NUMA node. * hw/core/machine.c::machine_numa_finish_cpu_init() to record CPU slots with no NUMA mapping set. * hw/core/machine-hmp-cmds.c::hmp_hotpluggable_cpus() to dump cluster-id.
