From afed5a5a7030a074a181d2a0ce8202de71a6ada4 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 10 May 2017 13:29:55 +0200 Subject: [PATCH] QMP: include CpuInstanceProperties into query_cpus output output if board supports CpuInstanceProperties, report them for each CPU thread listed. Main motivation for this is to provide these properties introspection via QMP interface for using in test cases to verify numa node to cpu mapping, which includes not only boards that support cpu hotplug and have this info in query-hotpluggable-cpus (pc/spapr) but also for boards that don't not support hotpluggable-cpus but support numa mapping (virt-arm).
