[Qemu-devel] [PATCH v5] hmp: add info iothreads command


From: Ting Wang
Subject: [Qemu-devel] [PATCH v5] hmp: add info iothreads command
Date: Fri, 26 Jun 2015 16:07:13 +0800

Make "info iothreads" available on the HMP monitor.

For example, the results are as follows when executing qemu
command with "-object iothread,id=iothread-1 -object 
iothread,id=iothread-2".
(qemu) info iothreads
iothread-1: thread_id=123
iothread-2: thread_id=456
