Subject: [Qemu-devel] [PATCH] hw/i386: add legacy cpu hotplug for pc-lite
Date: Tue, 2 Oct 2018 09:20:53 +0800 [thread overview]
Message-ID: <1538443253-6480-1-git-send-email-wei.guo.simon@linux.alibaba.com> (raw)
From: Simon Guo <wei.guo.simon@linux.alibaba.com>
Currently pc-lite cpu hot plug will leads to error like:
"acpi: device plug request for not supported device type: host-x86_64-cpu"
. However pc_lite_machine_options() didn't setup flag legacy_cpu_hotplug
correctly, which will leads to a later mess state, and causes the error
above.
This patch corrects this by initialize legacy_cpu_hotplug flag
correctly at pc_lite_machine_options().
