Subject: [PATCH v5 5/8] mips/cps: Use start-powered-off CPUState property
Date: Tue, 18 Aug 2020 23:42:17 -0300	[thread overview]
Message-ID: <20200819024220.587612-6-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20200819024220.587612-1-bauerman@linux.ibm.com>

Instead of setting CPUState::halted to 1 in main_cpu_reset(), use the
start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.

Also change creation of CPU object from cpu_create() to object_new() and
qdev_realize_and_unref() because cpu_create() realizes the CPU and it's not
possible to set a property after the object is realized.
