X-Received-From: 59.151.112.132 Subject: [Qemu-devel] [PATCH v3] vl: Move the cpu_synchronize_all_post_init() after generic devices initialization X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: izumi.taku@jp.fujitsu.com, caoj.fnst@cn.fujitsu.com, fanc.fnst@cn.fujitsu.com, qemu-devel@nongnu.org, Dou Liyang Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP At the Qemu initialization, we call the cpu_synchronize_all_post_init() to synchronize All CPU states to KVM in the ./vl.c::main(). Currently, it is called before we initialize the CPUs, which is created by "-device" command and parsed by generic devices initialization, So, these CPUs may be ignored to synchronize. The patch moves the cpu_synchronize_all_post_init func after generic devices initialization to make sure that all the CPUs can be included.
