From 24f675cd3b1406f3af9f9b811bb6946d0e2e6ecf Mon Sep 17 00:00:00 2001 From: Thiago Jung Bauermann Date: Wed, 26 Aug 2020 02:55:34 -0300 Subject: [PATCH] sparc/sun4m: Use start-powered-off CPUState property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of setting CPUState::halted to 1 in secondary_cpu_reset(), use the start-powered-off property which makes cpu_common_reset() initialize it to 1 in common code. Now secondary_cpu_reset() becomes equivalent to main_cpu_reset() so rename the function to sun4m_cpu_reset(). Also remove setting of cs->halted from cpu_devinit(), which seems out of place when compared to similar code in other architectures (e.g., ppce500_init() in hw/ppc/e500.c). Finally, 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.
